Description

Technical Field

[0001] This utility model relates to the field of compressor controller technology, and in particular to a high-sealing automotive air conditioning compressor controller. Background Technology

[0002] The automotive air conditioning compressor is the core component of the automotive air conditioning system. Its function is to compress low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas, providing power for the refrigeration cycle. The compressor controller (or compressor control unit, electromagnetic clutch controller) is a key electronic device that controls the operation of the compressor. Based on various sensor signals such as the vehicle interior temperature setting, ambient temperature, and engine load, it controls the engagement and disengagement of the compressor's electromagnetic clutch (or, for variable displacement compressors, its displacement regulating valve) to precisely regulate the cooling capacity, ensuring driving comfort while also considering engine energy consumption. The engine compartment generates a large amount of heat during operation, and the ambient temperature in summer can easily exceed 80°C or even higher, placing stringent requirements on the controller's heat dissipation and the high-temperature resistance of its electronic components. Therefore, we redesigned a highly sealed automotive air conditioning compressor controller. Utility Model Content
