Abstract
A heat exchanger includes a first header pipe, a second header pipe, a third header pipe, a fourth header pipe and a plurality of flat tubes, the first header pipe is provided with a first space and a second space and a communicating passage for communicating the first space with the second space; when refrigerant flows from the first space of the first header pipe to the second header pipe along the flat tubes, a part of the refrigerant passes through the communicating passage and directly enters into the second space of the first header pipe, thus an overall flow resistance of the heat exchanger may be decreased to some extent. Besides, the flow quantity of the refrigerant in the third flow path is constant, however fluid state parameters may change, which may greatly improve the heat exchange capacity of the third flow path, thereby improving the heat exchange performance of the heat exchanger on the whole.
