Abstract

The invention discloses a plate-fin type cold storage apparatus. The plate-fin type cold storage apparatus comprises a shell, wherein a flowing medium inlet and a flowing medium outlet are formed in the shell; a shunt device and multiple layers of micro-channel cold plates are arranged in the shell; flowing medium channels are formed in the micro-channel cold plates; the front end of the shunt device is connected with the flowing medium inlet in a sealing manner; the two ends of the each layer of micro-channel cold plates are connected with the tail end of the shunt device and the flowing medium outlet in a sealing manner respectively; fins are arranged between adjacent two layers of micro-channel cold plates in a tilted manner; the fins are provided with shutter structures; and the spaces between the fins are filled with phase-changing materials. The plate-fin type cold storage apparatus adopts a plate-fin type heat exchanger core structure, and is compact in structure and small in size.

Description

technical field [0001] The invention mainly relates to the field of cold storage devices, in particular to a plate-fin type cold storage device. Background technique [0002] For the cooling equipment of intermittent and violent exothermic equipment such as high-power lasers, in order to solve the problem of unequal demand time for cooling water, the cooling capacity of the refrigeration unit is stored in the cold storage medium through the cold storage device, and it is released quickly when the cold peak is used. , in order to achieve the purpose of meeting the actual cooling demand of production, achieve the purpose of shifting peaks and filling valleys, thereby reducing the assembly capacity and operating costs of refrigerators, etc. It can be seen that cold storage technology can play a role in shifting peaks and filling valleys for cooling demand , Fully improve energy utilization efficiency. [0003] The main structure of the existing cold storage device is a tube-fi...
