High-pressure fluid capillary heat exchanger and preparation method thereof

The high-pressure fluid capillary tube heat exchanger comprises an upper sealing plate and a lower sealing plate, a plurality of runner layers are arranged between the upper sealing plate and the lower sealing plate, each runner layer comprises a gasket, a plurality of capillary tubes are laid on the gasket, and a partition plate is arranged between every two adjacent upper and lower layers of runners; and the capillary tubes on the upper and lower adjacent layers are staggered. The heat exchanger has the advantages of being compact in size, high in power density, high in pressure bearing capacity, resistant to high temperature, even in heat exchange, long in service life and the like, an etching process is omitted in the machining process, hole-to-hole pipe penetrating is not needed, the manufacturing technological process is reduced, and the production period is shortened. The manufactured heat exchanger integrates all the advantages of a PCHE printed circuit board type heat exchanger and a capillary tube b
