Background technique

Heat dissipation is an important issue in current refrigeration equipment. For example, ice making machine is a device used to make ice cubes or cooling liquids in industrial and household applications. Ice machines achieve refrigeration effects through compression refrigeration technology and are widely used in the catering industry, medical treatment, food processing and other fields. However, the ice machine will generate heat during operation. In order to ensure the normal operation of the ice machine, this heat needs to be Effectively dissipate.

Existing ice machines usually use fans to dissipate heat from the condenser of the ice machine, and have multiple vents on the side walls of the ice machine body for air convection heat dissipation. The vents are in contact with the outside air and utilize the principle of heat conduction. The heat inside the ice machine is discharged through convection.

However, in actual use, there are still certain shortcomings:

1. The traditional vents are not equipped with guide air ducts. The air near the condenser is heated and expands to generate thrust, making it difficult for the air to flow to the condenser in a concentrated manner, affecting the heat dissipation effect;

2. The traditional vents are located on the side walls of the ice machine. Dust in the air will accumulate at the vents due to the influence of gravity, and the inside of the ice machine will be in direct contact with the air, which may cause the ice machine to malfunction.
