Technical Field

The utility model relates to the technical field of refrigerators, in particular to a frequency conversion controller for a refrigerator compressor.

Background technique

Refrigerators are devices that preserve food and other items at low temperatures. They are divided into household and commercial types. Commercial freezers are used in restaurants, bars, food processing and supermarkets. With the rapid development of science and technology, household refrigerators are also divided into fixed-frequency refrigerators and variable-frequency refrigerators. Among them, variable-frequency refrigerators have more advanced technology, lower energy consumption and longer preservation time, making them more widely used.

The prior art has the following problems:

The existing frequency conversion refrigerators have a frequency conversion controller as a core component inside. However, since refrigerators are generally used 24 hours a day, the temperature of the frequency conversion controller will continue to rise due to long-term use. When the temperature is too high, it will cause damage to the frequency conversion controller, resulting in a reduction in the service life of the refrigerator.
