Micro-channel plate heat exchanger with triangular corrugated flowing channel

Abstract

The invention discloses a micro-channel plate heat exchanger with a triangular corrugated flowing channel. The micro-channel plate heat exchanger comprises a channel plate, partition layer plates, clamping plates, hot fluid inlet-outlets, cold fluid inlet-outlets and liquid collecting hole channels. The partition layer plates are arranged on two sides of the channel plate, the channel plate and the partition layer plates are alternatively stacked and pressed to form a cold and hot fluid heat exchange channel, fluid distribution channels are formed in the partition layer plates, the cold and hot fluid heat exchange channel is communicated with the fluid distribution channels, and the liquid collecting hole channels are formed in four corners of the channel plate. The clamping plates are arranged on the outer sides of the channel plate and the partition layer plates, and the hot fluid inlet-outlets and the cold fluid inlet-outlets are formed in the clamping plates and are respectively connected with the liquid collecting hole channels. The micro-channel plate heat exchanger is small in size, compact in structure, large in heat transfer area per unit size, high in heat exchange efficiency, low in heat loss, convenient to install and clean, long in service life and free of welding heat resistance and is suitable for high-precision electronic devices, cooling heat-dispassion parts of precise instruments and micro-electronic mechanical systems.

Description

【Technical field】 [0001] The invention relates to the technical field of microchannel heat exchangers, in particular to the technical field of microchannel plate heat exchangers with triangular corrugated flow channels. 【Background technique】 [0002] Compared with traditional heat exchangers, microchannel heat exchangers have many advantages such as compact structure, light weight, high heat exchange efficiency, safe operation, and high reliability. They can meet the requirements of small space and compact structure, and are widely used in various occasions. . The rapid development of micro-products at this stage has also brought about the problem of micro-scale heat transfer. For example, in the rapid development of the microelectronics industry, the improvement of the heat dissipation performance of electronic components has become an urgent problem that hinders its performance development. Micro-channel heat exchangers can be divided into micro-micro-channel heat exchan...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art, and propose a microchannel plate heat exchanger with a triangular corrugated flow channel. There are no welded joints inside the heat exchanger, which solves a series of thermal resistance and flow resistance problems caused by welding. The design of micro-channels increases the heat transfer area of ​​the heat exchanger, thereby improving the heat transfer efficiency.
