1. A heat exchange apparatus, comprising:
a heat exchanger comprising a first pipe, a second pipe, and a plurality of heat exchange tubes, the first pipe and the second pipe being arranged spaced apart from each other, the plurality of heat exchange tubes being arranged spaced apart along a length direction of the first pipe,
wherein one end of the plurality of heat exchange tubes is inserted into the first pipe to be communicated with the first pipe, and another end of the plurality of heat exchange tubes is inserted into the second pipe to be communicated with the second pipe,
wherein the plurality of heat exchange tubes comprises a channel, the channel communicating the first pipe and the second pipe,
wherein each of the plurality of heat exchange tubes comprise a first straight section, a second straight section, and a connecting section, an angle between a length direction of the first straight section and a length direction of the second straight section is greater than or equal to 0° and less than 180°,
wherein the heat exchanger further comprises edge plates, each of the edge plates being disposed on an outer side of the plurality of heat exchange tubes in the length direction of the first pipe;
a refrigerant adjustment component,
wherein at least part of the refrigerant adjustment component is disposed on an outer side of the edge plates in the length direction of the first pipe,
wherein the refrigerant adjustment component comprises a cavity configured to accommodate refrigerant and an outer wall enclosing the cavity,
wherein the outer wall of the refrigerant adjustment component has an opening for refrigerant flow, and
wherein an angle between an axis in a length direction of at least part of the outer wall of the refrigerant adjustment component and an axis in the length direction of the first pipe is greater than 0° and less than or equal to 90°;
a first connecting member,
wherein the first connecting member communicates the opening of the refrigerant adjustment component and the first pipe, and in a direction of gravity, the opening of the refrigerant adjustment component is disposed higher than a communication position between the first connecting member and the first pipe; and
a mounting member, the mounting member being disposed on the outer side of the edge plates in the length direction of the first pipe, and the refrigerant adjustment component is fixedly connected to the mounting member,
wherein the mounting member comprises a first side surface and a second side surface arranged spaced apart in the length direction of the first pipe, and the refrigerant adjustment component is connected to at least one of the first side surface and the second side surface of the mounting member.
