Description

Technical Field

[0001] The utility model relates to the field of compressor controllers, in particular to a carbon dioxide heat pump type compressor controller. Background Art

[0002] In the prior art, a compressor controller generally includes a housing and a control board arranged in the housing. An opening connected to the external environment is provided on the rear side wall of the housing, and the connection line of the control board extends from the opening to the external environment. However, since the compressor controller is generally installed outdoors and the housing is directly connected to the external environment through this opening, dust in the external environment can easily enter the housing, thereby aggravating the aging of the control board and the connection line, and eventually causing damage to the internal control board of the compressor controller and failure to work normally.

[0003] For example, the patented compressor controller (Announcement No.: CN207340373U) solves the problem of compressor controllers in the prior art being generally dustproof and having poor heat dissipation. The compressor controller in this case includes a housing and a control board arranged in the housing. The housing includes a front cover with multiple heat dissipation ribs and a rear cover embedded in the front cover. In this case, a thermal pad is affixed to the inner surface of the front cover, and the thermal pad is in thermal contact with the control board to enhance the heat dissipation of the housing. A cable hole is provided at a corner of the mounting slot of the rear cover to improve the sealing of the entire housing. Compared with the prior art, the compressor controller in this case has the advantages of being dustproof and having good heat dissipation.

[0004] The aforementioned patent utilizes a thermal pad and housing to achieve dustproof and heat dissipation for the compressor controller. However, in daily use, the sealed housing prevents heat from dissipating quickly, weakening the device's heat dissipation. Therefore, the invention of a CO2 heat pump compressor controller to address this issue is crucial. Utility Model Content
