A phase change cold storage device capable of releasing cold quickly

Abstract

The utility model solves the problem that the equipment of adopting temperature difference cold storage mode currently occupies larger space, relates to cold storage device technical field, especially relates to a phase change cold storage device of quick release cold, including first coil, a plurality of second coil and the fin group of expansion joint in first coil, second coil, both sides of fin group are equipped with end plate no. 1, and first coil, second coil all pass through end plate no. 1, box, its sleeve set in the outside of cold storage device and is combined with fin group, and its inner wall and end plate no. 1 are sealedly connected, and phase change heat transfer medium is injected between the inner wall of box to fin group, first coil and second coil, and the upper portion of box is left with phase change expansion space. The device is provided with refrigeration flow path and cold flow path. The utility model adopts phase change heat transfer medium, and combines the compact ice storage heat exchanger of refrigeration flow path and cold loop of space interval arrangement, and heat transfer coefficient is very high, and ice melting speed is very fast.
