Abstract

The present application discloses a heat exchange apparatus and a heat pump system provided with same. The heat exchange apparatus includes a heat exchanger and a refrigerant adjustment container with an opening, the heat exchanger includes a first header, a second header and a plurality of heat exchange tubes, two ends of each heat exchange tube are respectively connected to the first header and the second header so as to connect the first header and the second header, and the opening of the refrigerant adjustment container is either of the first header and the second header. The heat exchange apparatus in the present application has the refrigerant adjustment container for adjusting refrigerant in the system, so as to improve system effectiveness.

First claim

The invention claimed is:

1. A heat exchange apparatus, comprising: a heat exchanger and a refrigerant adjustment container with an opening, wherein the heat exchanger comprises a first header, a second header and a plurality of heat exchange tubes, two ends of each heat exchange tube are respectively connected to the first header and the second header so as to connect the first header and the second header, and the opening of the refrigerant adjustment container is connected to either of the first header and the second header;
wherein each heat exchange tube comprises straight sections and a bent section between the straight sections; wherein the refrigerant adjustment container comprises a first pipe section extending in an axial direction of the either header and a second pipe section connected between the either header and the first pipe section;
wherein the refrigerant adjustment container is located on the left side of a straight section on the left side of the bent section and is arranged close to the first header, and an extension direction of the first pipe section is the same as that of the first header and the first pipe section is located at the upper left of the first header; and an extension direction of the second pipe section is slanted to the left at a specific angle with respect to an extension direction of the straight section on the left side of the bent section.

2. The heat exchange apparatus according to claim 1 , wherein the refrigerant adjustment container is located outside the heat exchanger and close to the either header.

3. The heat exchange apparatus according to claim 2 , wherein the refrigerant adjustment container is a refrigerant adjustment pipe, and the refrigerant adjustment pipe comprises a first pipe section extending in an axial direction of the either header and a second pipe section connected between the either header and the first pipe section.

4. The heat exchange apparatus according to claim 1 , wherein the refrigerant adjustment container comprises a refrigerant adjustment tank.

5. The heat exchange apparatus according to claim 1 , wherein refrigerant adjustment container is higher than the either header in an up-down direction.
