The invention discloses a heat exchanger and an air conditioner. The heat exchanger comprises at least one heat exchange unit; the heat exchange unit comprises a micro-channel core body and heat dissipation fins; the micro-channel core body is provided with a plurality of medium channels for heat exchange media to flow; the heat dissipation fins are arranged on two opposite sides of the micro-channel core body in the thickness direction; and the micro-channel core body and the heat dissipation fins are formed in an integrated mode. According to the heat exchanger provided by the embodiment ofthe invention, the heat exchange unit of the heat exchanger comprises the heat dissipation fins and the micro-channel core body, and the micro-channel core body and the heat dissipation fins are formed in the integrated mode, so that zero contact thermal resistance is realized between the heat dissipation fins and the micro-channel core body, the heat exchange efficiency and the heat exchange effect of the heat dissipation fins and the micro-channel core body can be improved, the heat exchanger is enabled to have higher heat exchange efficiency and good heat exchange effect, and the heating efficiency and / or the refrigerating efficiency of a complete machine can be improved. When the heat exchanger is applied to the complete machine, the heat exchanger may not be equipped with a fan, suchthat no wind or zero wind is realized, and the comfort is greatly improved.
Description
technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchanger and an air conditioner. Background technique [0002] In the related technology, mass-produced finned tube heat exchangers, the tubes and fins of the finned tube heat exchanger are combined through expansion tubes, the contact thermal resistance between the tubes and the fins is relatively large, and the distance between the fins and the tubes is relatively large. The low heat exchange efficiency leads to low heat exchange efficiency and poor heat exchange effect of the entire heat exchanger, which is not conducive to the improvement of the heating efficiency and / or cooling efficiency of the whole machine. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is to propose a kind of heat exchanger, the heat dissipation fi...
