Abstract

A heat exchange apparatus and a heat pump system provided with same are provided. 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.

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 two straight sections and a bent section between the two straight sections, and the refrigerant adjustment container is located below the bent sections of the plurality of heat exchange tubes and between the two straight sections of the plurality of heat exchange tubes, and a part of the refrigerant adjustment container is located at an upper right of the first header and an upper left of the second header;
wherein the refrigerant adjustment container comprises a first pipe section extending in an axial direction of the either header and close to the either header and a second pipe section connected between the either header and the first pipe section; and an extension direction of the second pipe section is slanted to the right at a specific angle with respect to an extension direction of the straight section on a left side of the bent section.

2 . The heat exchange apparatus according to claim 1 , wherein the refrigerant adjustment container is a refrigerant adjustment pipe.

3 . The heat exchange apparatus according to claim 2 , wherein a hydraulic diameter of the refrigerant adjustment pipe is greater than ½ of a diameter of the either header.

4 . A heat pump system, comprising: a compressor, an indoor heat exchanger, and an outdoor heat exchanger, wherein an internal volume of one of the outdoor heat exchanger and the indoor heat exchanger is larger than that of the other heat exchanger,
and wherein the other heat exchanger comprises 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 two straight sections and a bent section between the two straight sections, and the refrigerant adjustment container is located below the bent sections of the plurality of heat exchange tubes and between the two straight sections of the plurality of heat exchange tubes, and a part of the refrigerant adjustment container is located at an upper right of the first header and an upper left of the second header; wherein the refrigerant adjustment container comprises a first pipe section extending in an axial direction of the either header and close to the either header and a second pipe section connected between the either header and the first pipe section; an extension direction of the second pipe section is slanted to the right at a specific angle with respect to an extension direction of the straight section on a left side of the bent section.

5 . The heat pump system according to claim 4 , wherein a hydraulic diameter of the refrigerant adjustment container is greater than ½ of a diameter of the either header.
