Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1, an embodiment of the present invention includes:
an energy storage type cryogenic refrigerator comprising: the refrigerator comprises a refrigerator body 1, a metal plate liquid-tight storage tank for storing cold accumulation working media, and a refrigeration pipeline. The metal plate liquid-tight storage tank is flat and is located in the heat preservation layer 12 of the refrigerator body 1, and the metal plate liquid-tight storage tank is flatly attached to the rear wall of the inner container 11 of the refrigerator body 1 in an adhesive (or welding) mode. The refrigerator comprises a refrigerator body 1, and is characterized in that a liquid filling port and a plug used for sealing the liquid filling port are arranged on a position, corresponding to a metal plate liquid-tight storage tank, of an inner container 11 of the refrigerator body 1, and the liquid filling port and a working medium filling port of the metal plate liquid-tight storage tank are communicated into a whole. The refrigeration pipeline is a copper pipe 4 which is coiled (bent) in the heat-insulating layer 12, and the copper pipe 4 is tightly attached to the outer walls of the upper, lower, left and right sides of the inner container 11 and is connected with a refrigeration element in the refrigerator body 1; in operation, cooling energy is provided to the inner container 11 through a refrigeration cycle.
