Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a cold exhaust pipe for refrigeration of a cold storage. Background Art

[0002] The radiator pipe is used in cold storage to ensure that there is more water and ice in the storage. Once the power is off, the temperature can be maintained for a period of time, which is suitable for vegetables, fruits, ice cream, cold drinks, fresh meat, etc. It also has the advantage of saving electricity.

[0003] The radiator pipe is prone to frost, which affects the refrigeration efficiency. The traditional solution is to wrap a heating wire around the surface of the radiator pipe. When frost forms, the heating wire is powered on to defrost. However, the heating wire is prone to breakage in an alternating hot and cold environment and requires frequent maintenance. At the same time, the heating wire covers the surface of the radiator pipe, reducing the heat exchange area of ​​the radiator pipe. To this end, we provide radiator pipes for cold storage refrigeration to solve the above problems. Utility Model Content
