Cooler

Abstract

A refrigerator based on microchannel heat recovery and heat exchange technology and coke soup effect processed by atomic diffusion fusion welding technology includes: inlet and outlet parts, heat recovery and heat exchange parts, throttling parts, and evaporation chamber. Wherein, the inlet and outlet part has an inlet and an outlet; the heat recovery part is composed of at least one high-temperature layer and at least one low-temperature layer adjacent to each other, and each layer has at least one channel, after the relatively high-temperature and high-pressure gas enters the channel of the high-temperature layer from the inlet Enter the throttling part to complete a throttling and cooling, and then flow to the evaporation chamber with a large space to throttling and cooling again. Due to the throttling and cooling, part of the gas is condensed into liquid, and the rest is low-temperature and low-pressure gas. The two are mixed together to form a low-temperature and low-pressure gas. Vapor-liquid mixture; the low-temperature and low-pressure vapor-liquid mixture keeps the evaporation chamber at a low temperature and cools the high-temperature devices connected to it, and the gas in the evaporation chamber flows back into the channel of the low-temperature layer to exchange heat with the relatively high-temperature and high-pressure gas in the channel of the adjacent high-temperature layer. Exit discharge.

Description

technical field [0001] A heat transfer technology based on microchannel heat transfer technology and processed by atomic diffusion fusion welding technology, which is used in the detection and guidance of satellites, weapons, radars, etc., low-temperature electron microscopy, low-temperature medicine, and heat dissipation of electronic components. Cooler with burnt soup effect. Background technique: [0002] In gas liquefaction and low-temperature refrigeration technology, using the Joule-Thomson throttling refrigeration effect of actual gas (hereinafter referred to as J-T effect) is the most commonly used method, and as early as 1895, a J-T effect throttling refrigeration cycle was developed. For industrial gas liquefaction [1] . The development of miniature J-T effect refrigerators began in the 1950s. It usually consists of a counterflow recuperator, a throttling element and an evaporation chamber. Generally, a stainless steel tube with a small diameter (about φ0.5-φ1mm...
