Flat-plate-type water sublimation cold plate for aerospace radiation

Abstract

The invention provides a flat-type-type water sublimation cold plate for aerospace radiation. The flat-type-type water sublimation cold plate is composed of a cover plate, a teflon cushion block, a sealing ring, a perforated plate, a metal foam or micropore fin, a base body, a water supply channel sealing pressing plate, a water supply pipeline, a connecting bolt and a lock nut. A water supply channel is formed in the bottom face of the base body in the circumferential direction. The installation space matched with the metal foam or micropore fin, the perforated plate and the sealing ring is reserved in the upper surface of the base body. The metal foam or micropore fin is located inside the installation space, the perforated plate is located above the metal foam or micropore fin, and the metal foam or micropore fin is compressed onto the base body through welding of the perforated plate and the base body. A plurality of through holes are formed in the contact face of the base body and the metal foam or micropore fin in the thickness direction. The through holes are communicated with the water supply channel. A reinforcing rib and an air outlet channel are arranged on the cover plate. According to the flat-type-type water sublimation cold plate for aerospace radiation, the triple-point characteristics of water working media are utilized for sublimating the water working media through the structural design, and therefore the radiating function is achieved.
