Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated trucks, and more specifically, to a defrosting device for refrigerated trucks. Background Art

[0002] A refrigerated truck is an enclosed van used to transport frozen or fresh goods, and is a special transport vehicle equipped with a refrigeration unit, which is commonly used for frozen foods, dairy products, fruits and vegetables, vaccines, drugs, etc. At present, during the use of refrigerated trucks, since frost will form on the inner wall of the compartment during the refrigeration process, affecting the refrigeration heat transfer effect, a defrosting device needs to be set up. However, in the existing devices, it is necessary to heat up to melt the frost ice for defrosting. During the defrosting process, the refrigeration function of the refrigerated truck is not stopped, which easily leads to a slower defrosting effect and a low defrosting efficiency. In the case of one cold and one hot, it is also easy to damage the refrigeration function of the refrigerated truck. To solve the above problems, we propose the following device.
