Description

Technical Field

[0001] This utility model belongs to the field of refrigeration technology, and specifically relates to an overheat protection device for refrigeration equipment. Background Technology

[0002] Refrigeration equipment is primarily used in the marine industry for refrigerating food for crew members, preserving cargo, and regulating cabin air temperature during hot seasons. The core components of this equipment include compressors, expansion valves, evaporators, condensers, and related accessories and piping systems. The working principle of refrigeration equipment is to transfer heat from the object being cooled to the surrounding environment using refrigerant, thereby achieving a cooling effect. During operation, overheat protection devices are required to prevent damage from overheating.

[0003] Chinese patent document CN220417790U discloses an overheat protection device specifically for the heat dissipation mechanism of refrigeration equipment. This device mainly consists of a protective shell, a water tank, a water pump, a protective cover, a storage tank, and nozzles. The water tank, containing the water pump, is located at the bottom of the protective shell. The protective cover is bolted to the top of the protective shell, and the storage tank is fixed above the cover. Evenly distributed nozzles are located at the bottom of the storage tank. An outlet connected to the nozzles is located at the bottom of the storage tank, and the water pump's outlet is connected to the inside of the storage tank via a water pipe. This device aims to cool the heat dissipation mechanism inside the protective shell, preventing damage due to overheating and ensuring effective cooling.

[0004] However, in practical applications, the overheat protection device described in CN220417790U has certain limitations. Although the device can protect refrigeration equipment from overheating, its cooling method of spraying water has the following shortcomings: after absorbing heat, the water cannot cool down again, resulting in the circulating water temperature being the same as the temperature of the refrigeration equipment, thus failing to continue its cooling effect. This defect makes it difficult for the refrigeration equipment to return to normal operation under overheating conditions, affecting the stability and ease of use of the equipment.
