In the first direction D1of the heat exchanger100, the second heat exchanger core segments12of the two first heat exchanger units1may be positioned on the outer side of the first heat exchanger core segments11of the two first heat exchanger units1.

Referring toFIGS.17-18, in the embodiments of the present invention, the heat exchanger core connection segments13of the two first heat exchanger units1are positioned on a side of the heat exchanger100in a third direction D3, thereby the second heat exchanger core segment12of the first heat exchanger unit1is positioned on a side of the heat exchanger100in the third direction D3. The third direction D3of the heat exchanger100is perpendicular to the first direction D1of the heat exchanger100and the second direction D2of the heat exchanger100, the second direction D2of the heat exchanger100being perpendicular to the first direction D1of the heat exchanger100and being the up and down direction of the heat exchanger100. The third direction D3may be substantially horizontal direction.

Referring toFIGS.1-6,9-13,17and19-21, in the embodiments of the present invention, the first heat exchanger unit1further includes: two first headers16, one of which is connected and in fluid communication with the first heat exchange pipe18of the first heat exchanger core segment11of the first heat exchanger unit1on a side of the first heat exchanger core segment11of the first heat exchanger unit1away from the heat exchanger core connection segment13of the first heat exchanger unit1in the third direction D13of the first heat exchanger unit1, and the other of which is connected and in fluid communication with the first heat exchange pipe18of the second heat exchanger core segment12of the first heat exchanger unit1on a side of the second heat exchanger core segment12of the first heat exchanger unit1away from the heat exchanger core connection segment13of the first heat exchanger unit1in the third direction D13of the first heat exchanger unit1. The two first headers16include: a first header16for heat exchange medium to flow into the first heat exchanger unit1, and a first header16for the heat exchange medium to flow out of the first heat exchanger unit1. The two first headers16may be substantially parallel to each other or not parallel to each other.

Referring toFIGS.1-3and5, in the embodiments of the present invention, the two first heat exchanger units1form an inverted V-shaped shape, the heat exchanger core connection segments13of the two first heat exchanger units1are positioned on the lower side of the heat exchanger100, one first header16, which is connected with the first heat exchanger core segment11of the first heat exchanger unit1, of each of the two first heat exchanger units1is used for the heat exchange medium to flow out of the first heat exchanger unit1, and the other first header16, which is connected with the second heat exchanger core segment12of the first heat exchanger unit1, of each of the two first heat exchanger units1is used for the heat exchange medium to flow into the first heat exchanger unit1. According to the embodiments of the present invention, the second heat exchanger core segment12and a portion of the first heat exchanger core segment11of the first heat exchanger unit1overlapped with the second heat exchanger core segment12form a double row heat exchanger core region, and a region of the first heat exchanger core segment11of the first heat exchanger unit1, which is not overlapped with the second heat exchanger core segment12, forms a single row heat exchanger core region. When the heat exchanger100is used as an evaporator, a refrigerant flows into the heat exchanger from the first header16connected with the second heat exchanger core segment12of the first heat exchanger unit1, and flows out of the heat exchanger from the first header16connected with the first heat exchanger core segment11of the first heat exchanger unit1. Air is blown from a windward side of the heat exchanger100(a side being away from a region between the two first heat exchanger units1in 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 segment12. Since the second heat exchanger core segment12is 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 segment11at a leeward side (a side facing the region between the two first heat exchanger units1in the first direction D1) is decreased, and there is less condensed water at the first heat exchanger core segment11. In addition, due to addition of the second heat exchanger core segment12, 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 segment12, the heat exchange area of the heat exchanger is also increased, and thus the heat exchange capacity is improved.

Referring toFIG.21, in the embodiments of the present invention, the two first heat exchanger units1form a V-shaped shape, the heat exchanger core connection segments13of the two first heat exchanger units1are positioned on the lower side of the heat exchanger100, and one first header16, which is connected with the first heat exchanger core segment11of the first heat exchanger unit1, of each of the two first heat exchanger units1is used for the heat exchange medium to flow into the first heat exchanger unit1, and the other first header16, which is connected with the second heat exchanger core segment12of the first heat exchanger unit1, of each of the two first heat exchanger units1is used for the heat exchange medium to flow out of the first heat exchanger unit1. 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 segment12, the heat exchange area is increased and thus the heat exchange capacity is improved.

Referring toFIGS.3,5and20, in the embodiments of the present invention, the heat exchanger100further includes a heat exchanger connection segment5connecting the first heat exchanger core segments11of the two first heat exchanger units1. The heat exchanger core connection segment13of each of the two first heat exchanger units1is positioned on a side of the first heat exchanger core segment11of the first heat exchanger unit1away from the heat exchanger connection segment5in the third direction D13of the first heat exchanger unit1. The two first heat exchanger units1and the heat exchanger connection segment5can be formed by bending a flat heat exchanger. In addition, the heat exchanger100shown inFIGS.3,5and20can be formed by bending the second heat exchanger unit2shown inFIGS.14-16. Each of the two first heat exchanger units1further includes: a first header16, which is connected and in fluid communication with the first heat exchange tube18of the second heat exchanger core segment12of the first heat exchanger unit1.

Referring toFIGS.3and5, in the embodiments of the present invention, the two first heat exchanger units1form an inverted V-shaped shape, and the heat exchanger core connection segments13of the two first heat exchanger units1are positioned on the lower side of the heat exchanger100. Thereby, the second heat exchanger core segments12of the two first heat exchanger units1are positioned on the lower side of the heat exchanger100. The first header16of one of the two first heat exchanger units1is used for the heat exchange medium to flow into the two first heat exchanger units1, and the first header16of the other of the two first heat exchanger units1is used for the heat exchange medium to flow out of the two first heat exchanger units1.

Referring toFIG.3, in the embodiments of the present invention, the second heat exchanger core segment12and a portion of the first heat exchanger core segment11of the first heat exchanger unit1overlapped with the second heat exchanger core segment12form a double row heat exchanger core region, and a region of the first heat exchanger core segment11of the first heat exchanger unit1, which is not overlapped with the second heat exchanger core segment12, forms a single row heat exchanger core region. When the heat exchanger100is used as an evaporator, the refrigerant flows into the heat exchanger from the first header16connected with the second heat exchanger core segment12of the one first heat exchanger unit1, and flows out of the heat exchanger from the first header16connected with the second heat exchanger core segment12of the other first heat exchanger unit1. Air is blown from a windward side of the heat exchanger100(a side being away from the region between the two first heat exchanger units1in 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 segment12. Since the second heat exchanger core segment12is 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 segment11at a leeward side (a side facing the region between the two first heat exchanger units1in the first direction D1) is decreased, and there is less condensed water at the first heat exchanger core segment11. In addition, due to addition of the second heat exchanger core segment12, 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 segment12, the heat exchange area of the heat exchanger is also increased, and thus the heat exchange capacity is improved.

Referring toFIGS.4and6, in the embodiments of the present invention, the heat exchanger100includes one first heat exchanger unit1, and the heat exchanger100further includes one third heat exchanger unit3and a heat exchanger connection segment5. The third heat exchanger unit3has a flat shape, and the third heat exchanger unit3has a heat exchanger core30. The heat exchanger connection segment5connects the first heat exchanger core segment11of the one first heat exchanger unit1and the heat exchanger core30of the one third heat exchanger unit3, wherein the one first heat exchanger unit1and the one third heat exchanger unit3are oppositely arranged in the first direction D1of the heat exchanger100to form a V-shaped or inverted V-shaped shape.
