Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a Stirling refrigerator compressor for a HOT device. Background Art

[0002] A Stirling refrigerator is a refrigeration system based on the Stirling cycle principle. It usually uses a piston compressor to achieve the refrigeration effect. The Stirling refrigerator achieves refrigeration by alternately expanding and compressing gas without the use of an evaporator and condenser, so it can be used in some special application scenarios.

[0003] After searching, a Stirling refrigerator compressor for HOT devices with announcement number CN219119395U includes a base, a linear drive unit, a piston and an elastic member, a piston cavity matched with the piston is arranged in the base, and the linear drive unit is used to drive the piston to move; it also includes an assembly seat, the first end of the two ends of the elastic member is connected to the assembly seat, and the second end of the two ends of the elastic member is connected to the piston; a take-out opening that enables the elastic member to be taken out is provided at the end of the base, and the assembly seat blocks the take-out opening. A take-out opening is provided at the end of the base, and a corresponding assembly connection is provided between the assembly seat and the base, so that during the assembly process, the elastic member can be tested, so that when the parameters such as the length and / or stiffness of the elastic member do not meet the requirements, a more suitable elastic member can be replaced, so that the final operating frequency of the Stirling refrigerator compressor is consistent with the vibration frequency of the linear drive unit, so as to better achieve resonance, reduce power consumption, and thus facilitate adjustment.

[0004] The above patent mentioned that "the final operating frequency of the Stirling refrigerator compressor is consistent with the vibration frequency of the linear drive unit to better achieve resonance, reduce power consumption, and facilitate adjustment." However, in the actual use process, although the power consumption of the compressor can be reduced, the compressor cannot be protected from collision. If the Stirling refrigerator compressor collides or is impacted by external force during operation, it may cause damage to mechanical parts such as the piston, crank connecting rod, cylinder body, etc., which will affect the normal operation of the compressor and may even cause the failure of the entire refrigeration system. Therefore, in response to the above problems, a Stirling refrigerator compressor for a HOT device is proposed. Utility Model Content

[0026] like Figure 2 , Figure 4As shown, the bottom inner wall of the connecting plate 3 is fixedly connected with a motor 16, and the driving end of the motor 16 is fixedly connected with a gear 17.
