[0059]Referring to FIGS. 1-3, 5 and 17-21, in the embodiments of the present invention, the heat exchanger 100 includes two first heat exchanger units 1, which are oppositely arranged in a first direction D1 of the heat exchanger 100 to form a V-shaped or inverted V-shaped shape.

In the first direction D1 of the heat exchanger 100, each of the second heat exchanger core segments 12 of the two first heat exchanger units 1 may be positioned on the inner or outer side of the first heat exchanger core segments 11 of the two first heat exchanger units 1, or in the first direction D1 of the heat exchanger 100, the second heat exchanger core segments 12 of the two first heat exchanger units 1 may be positioned on the inner or outer side of the first heat exchanger core segments 11 of the two first heat exchanger units 1. In the first direction D1 of the heat exchanger 100, the second heat exchanger core segments 12 of the two first heat exchanger units 1 may be positioned on the outer side of the first heat exchanger core segments 11 of the two first heat exchanger units 1.

[0060]Referring to FIGS. 17-18, in the embodiments of the present invention, the heat exchanger core connection segments 13 of the two first heat exchanger units 1 are positioned on a side of the heat exchanger 100 in a third direction D3, thereby the second heat exchanger core segment 12 of the first heat exchanger unit 1 is positioned on a side of the heat exchanger 100 in the third direction D3. The third direction D3 of the heat exchanger 100 is perpendicular to the first direction D1 of the heat exchanger 100 and the second direction D2 of the heat exchanger 100, the second direction D2 of the heat exchanger 100 being perpendicular to the first direction D1 of the heat exchanger 100 and being the up and down direction of the heat exchanger 100. The third direction D3 may be substantially horizontal direction.

[0061]Referring to FIGS. 1-6, 9-13, 17 and 19-21, in the embodiments of the present invention, the first heat exchanger unit 1 further includes: two first headers 16, one of which is connected and in fluid communication with the first heat exchange pipe 18 of the first heat exchanger core segment 11 of the first heat exchanger unit 1 on a side of the first heat exchanger core segment 11 of the first heat exchanger unit 1 away from the heat exchanger core connection segment 13 of the first heat exchanger unit 1 in the third direction D13 of the first heat exchanger unit 1, and the other of which is connected and in fluid communication with the first heat exchange pipe 18 of the second heat exchanger core segment 12 of the first heat exchanger unit 1 on a side of the second heat exchanger core segment 12 of the first heat exchanger unit 1 away from the heat exchanger core connection segment 13 of the first heat exchanger unit 1 in the third direction D13 of the first heat exchanger unit 1. The two first headers 16 include: a first header 16 for heat exchange medium to flow into the first heat exchanger unit 1, and a first header 16 for the heat exchange medium to flow out of the first heat exchanger unit 1. The two first headers 16 may be substantially parallel to each other or not parallel to each other.

[0062]Referring to FIGS. 1-3 and 5, in the embodiments of the present invention, the two first heat exchanger units 1 form an inverted V-shaped shape, the heat exchanger core connection segments 13 of the two first heat exchanger units 1 are positioned on the lower side of the heat exchanger 100, one first header 16, which is connected with the first heat exchanger core segment 11 of the first heat exchanger unit 1, of each of the two first heat exchanger units 1 is used for the heat exchange medium to flow out of the first heat exchanger unit 1, and the other first header 16, which is connected with the second heat exchanger core segment 12 of the first heat exchanger unit 1, of each of the two first heat exchanger units 1 is used for the heat exchange medium to flow into the first heat exchanger unit 1. According to the embodiments of the present invention, the second heat exchanger core segment 12 and a portion of the first heat exchanger core segment 11 of the first heat exchanger unit 1 overlapped with the second heat exchanger core segment 12 form a double row heat exchanger core region, and a region of the first heat exchanger core segment 11 of the first heat exchanger unit 1, which is not overlapped with the second heat exchanger core segment 12, forms a single row heat exchanger core region. When the heat exchanger 100 is used as an evaporator, a refrigerant flows into the heat exchanger from the first header 16 connected with the second heat exchanger core segment 12 of the first heat exchanger unit 1, and flows out of the heat exchanger from the first header 16 connected with the first heat exchanger core segment 11 of the first heat exchanger unit 1. Air is blown from a windward side of the heat exchanger 100 (a side being away from a region between the two first heat exchanger units 1 in the first direction D1) towards the heat exchanger. In the double row heat exchanger core region at the bottom of the heat exchanger, the air first passes through the second heat exchanger core segment 12. Since the second heat exchanger core segment 12 is a refrigerant inlet segment, heat exchange will be more active, so that water vapor in the air is condensed in advance. Thereby, a moisture content of the air passing through the first heat exchanger core segment 11 at a leeward side (a side facing the region between the two first heat exchanger units 1 in the first direction D1) is decreased, and there is less condensed water at the first heat exchanger core segment 11. In addition, due to addition of the second heat exchanger core segment 12, the air resistance at the bottom of the heat exchanger (the double row heat exchanger core region) is increased, resulting in a decrease in the air flow velocity on the leeward side at the bottom. With the above two factors, the condensed water at the bottom of the heat exchanger will not be blown out by the air. At the same time, with provision of the second heat exchanger core segment 12, the heat exchange area of the heat exchanger is also increased, and thus the heat exchange capacity is improved.

[0063]Referring to FIG. 21, in the embodiments of the present invention, the two first heat exchanger units 1 form a V-shaped shape, the heat exchanger core connection segments 13 of the two first heat exchanger units 1 are positioned on the lower side of the heat exchanger 100, and one first header 16, which is connected with the first heat exchanger core segment 11 of the first heat exchanger unit 1, of each of the two first heat exchanger units 1 is used for the heat exchange medium to flow into the first heat exchanger unit 1, and the other first header 16, which is connected with the second heat exchanger core segment 12 of the first heat exchanger unit 1, of each of the two first heat exchanger units 1 is used for the heat exchange medium to flow out of the first heat exchanger unit 1. According to the embodiments of the present invention, when the heat exchanger is used as a condenser, with provision of the second heat exchanger core segment 12, the heat exchange area is increased and thus the heat exchange capacity is improved.

[0064]Referring to FIGS. 3, 5 and 20, in the embodiments of the present invention, the heat exchanger 100 further includes a heat exchanger connection segment 5 connecting the first heat exchanger core segments 11 of the two first heat exchanger units 1. The heat exchanger core connection segment 13 of each of the two first heat exchanger units 1 is positioned on a side of the first heat exchanger core segment 11 of the first heat exchanger unit 1 away from the heat exchanger connection segment 5 in the third direction D13 of the first heat exchanger unit 1. The two first heat exchanger units 1 and the heat exchanger connection segment 5 can be formed by bending a flat heat exchanger. In addition, the heat exchanger 100 shown in FIGS. 3, 5 and 20 can be formed by bending the second heat exchanger unit 2 shown in FIGS. 14-16. Each of the two first heat exchanger units 1 further includes: a first header 16, which is connected and in fluid communication with the first heat exchange tube 18 of the second heat exchanger core segment 12 of the first heat exchanger unit 1.

[0065]Referring to FIGS. 3 and 5, in the embodiments of the present invention, the two first heat exchanger units 1 form an inverted V-shaped shape, and the heat exchanger core connection segments 13 of the two first heat exchanger units 1 are positioned on the lower side of the heat exchanger 100. Thereby, the second heat exchanger core segments 12 of the two first heat exchanger units 1 are positioned on the lower side of the heat exchanger 100. The first header 16 of one of the two first heat exchanger units 1 is used for the heat exchange medium to flow into the two first heat exchanger units 1, and the first header 16 of the other of the two first heat exchanger units 1 is used for the heat exchange medium to flow out of the two first heat exchanger units 1.

[0066]Referring to FIG. 3, in the embodiments of the present invention, the second heat exchanger core segment 12 and a portion of the first heat exchanger core segment 11 of the first heat exchanger unit 1 overlapped with the second heat exchanger core segment 12 form a double row heat exchanger core region, and a region of the first heat exchanger core segment 11 of the first heat exchanger unit 1, which is not overlapped with the second heat exchanger core segment 12, forms a single row heat exchanger core region. When the heat exchanger 100 is used as an evaporator, the refrigerant flows into the heat exchanger from the first header 16 connected with the second heat exchanger core segment 12 of the one first heat exchanger unit 1, and flows out of the heat exchanger from the first header 16 connected with the second heat exchanger core segment 12 of the other first heat exchanger unit 1. Air is blown from a windward side of the heat exchanger 100 (a side being away from the region between the two first heat exchanger units 1 in the first direction D1) towards the heat exchanger. In the double row heat exchanger core region at the bottom of the heat exchanger, the air first passes through the second heat exchanger core segment 12. Since the second heat exchanger core segment 12 is a refrigerant inlet segment, heat exchange will be more active, so that water vapor in the air is condensed in advance. Thereby, a moisture content of the air passing through the first heat exchanger core segment 11 at a leeward side (a side facing the region between the two first heat exchanger units 1 in the first direction D1) is decreased, and there is less condensed water at the first heat exchanger core segment 11. In addition, due to addition of the second heat exchanger core segment 12, the air resistance at the bottom of the heat exchanger (the double row heat exchanger core region) is increased, resulting in a decrease in the air flow velocity on the leeward side at the bottom. With the above two factors, the condensed water at the bottom of the heat exchanger will not be blown out by the air. At the same time, with provision of the second heat exchanger core segment 12, the heat exchange area of the heat exchanger is also increased, and thus the heat exchange capacity is improved.

The second heat exchange tube 28 can be a flat tube.

[0070]Referring to FIGS. 9, 10 and 11, in the embodiments of the present invention, the heat exchanger 100 includes one first heat exchanger unit 1 and one second heat exchanger unit 2, wherein the one first heat exchanger unit 1 and the one second heat exchanger unit 2 are oppositely arranged in the first direction D1 of the heat exchanger 100 to form a V-shaped or inverted V-shaped shape.
