Description

Technical Field

[0001] This application relates to the technical field of refrigeration equipment, and in particular to a spray device for the condenser tube of a refrigeration equipment. Background Technology

[0002] A refrigeration machine is a machine that transfers heat from a cooled object at a lower temperature to the surrounding environment, thereby obtaining cooling. The heat transferred from the lower-temperature object is conventionally called cooling capacity. The working fluid that participates in the thermodynamic processes (energy conversion and heat transfer) within the refrigeration machine is called a refrigerant. The temperature range for refrigeration is typically above 120K, with temperatures below 120K falling into the category of cryogenic technology. Refrigeration machines are widely used in industrial and agricultural production and daily life.

[0003] A condenser spray system is an auxiliary system used to enhance the heat exchange efficiency of a condenser. It primarily enhances heat transfer by spraying water (or other cooling media) to form a liquid film on the condenser surface or directly cooling the tube bundle. Its main function is to utilize the evaporation of sprayed water on the condenser surface to absorb heat from the refrigerant or vapor inside the tubes, thus lowering its temperature. The sprayed water forms a uniform liquid film, increasing the contact area with the hot surface and improving heat exchange efficiency. Under high-temperature or high-load conditions, spraying can rapidly reduce the condenser surface temperature, preventing efficiency degradation.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: Existing technologies do not allow for easy adjustment of the spray direction of the nozzles, resulting in uneven spraying and affecting cooling efficiency. To address the problem of uneven spraying in existing technologies, this application utilizes a transmission wheel and transmission bar to drive the driven wheel and nozzle to rotate reciprocally, thereby achieving more uniform spraying onto the condenser tubes and improving cooling efficiency.
