Abstract

The invention relates to the field of heat exchangers, in particular to a micro-channel heat exchanger. The micro-channel heat exchanger comprises a body internally provided a plurality of heat exchange units, each heat exchange unit comprises a first flow channel and a second flow channel which are coaxially arranged in a sleeved manner and are independent of each other, the two ends of the firstflow channel in each of the multiple heat exchange units are connected to two first volume chambers, the two ends of the second flow channel in each of the multiple heat exchange units are connectedto two second volume chambers, the first volume chambers and the second volume chambers are arranged in the body and are independent of each other. The micro-channel heat exchanger is easy to processand has the better heat exchange effect.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a microchannel heat exchanger. Background technique [0002] With the rapid development of micro-chemical mechanical systems and micro-electromechanical systems, the integration of electronic devices is getting higher and higher, and the power consumption and heat generation per unit volume are also increasing, while the physical size is getting smaller and smaller. In order to solve Due to the high demand for heat exchange caused by heat concentration in tiny spaces, microchannel heat exchangers are used in the prior art. [0003] The microchannel heat exchangers in the prior art are all processed on the basis of thin metal sheets, which require precise cutting technologies such as photolithography, directional etching, and micro tools. At the same time, separate processing is required, and the forming process is complicated. The heat exchanger The complex structure and high proc...
