Abstract

The invention discloses a heat exchanger. The heat exchanger comprises a first flow collecting piece, a second flow collecting piece, a heat exchange core body, a shell and a partition plate, the shell, the first flow collecting piece and the second flow collecting piece act in a matched mode and are used for wrapping the heat exchange core body in a surrounding mode so as to seal an inner cavity of the shell, and the partition plate and the shell form a first cavity and a second cavity; and the first cavity and the second cavity communicate with each other at the end, away from a first opening and a second opening of the shell, of the partition plate, the first opening and the second opening are formed in the two opposite side walls of the shell, at least part of a first heat exchange pipe is located in the first cavity, and at least part of a second heat exchange pipe is located in the second cavity. According to the heat exchanger, the first fluid in the first heat exchange pipe exchanges heat with the second fluid in the first cavity, the first fluid in the second heat exchange pipe exchanges heat with the second fluid in the second cavity, the circulation path of the second fluid is approximately in a U shape, the heat exchange path of the second fluid can be increased, the heat exchange effect of the first fluid and the second fluid can be improved, and thus the heat exchange performance of the heat exchanger is improved.

Description

technical field [0001] The present application relates to the technical field of heat exchange, in particular to a heat exchanger. Background technique [0002] Heat exchangers, also known as heat exchangers, are widely used in heat exchange systems (such as air conditioning systems). The heat exchanger can be used for heat exchange between the refrigerant and the external air, and can also be used for heat exchange between the refrigerant and the cooling liquid. In the related art, the inner cavity of the shell of the heat exchanger is a cavity, and the heat exchange medium in the inner cavity of the shell is basically at the same temperature, and the heat exchange medium in the inner cavity of the shell and the inner cavity of the heat exchange tube The heat exchange between the heat exchange media in the cavity is not sufficient, and the heat exchange performance of the heat exchanger is not good. The inventors believe that there is a need for improvement in the heat ex...
