Abstract

The invention relates to a Vuilleumier refrigeration device driven by using fishing boat engine tail gas afterheat. A cold discharger and a heat discharger are arranged in a cylinder, and divide the total volume of the cylinder into three parts: a heat cavity, a cold cavity and middle two room-temperature cavities; a round plate with a small hole is arranged in the room-temperature cavity A; a shaft of the heat discharger is connected with a coil of a movable ring linear motor; the heat discharger is connected with the round plate through a spring B; the round plate is connected with the cold discharger through a spring A; the two room-temperature cavities are communicated through a connecting pipe; the connecting pipe is connected with a pipe in a water cooling radiator; and the water cooling radiator is communicated with the heat cavity through a heat regenerator and an afterheat recovery heat exchanger, and is communicated with the cold cavity through a cold regenerator and a cold end heat exchanger. The Vuilleumier refrigeration device adopts the movable ring linear motor to enable the output frequency of the motor to approach the vibration frequency of a vibration system generated by two dischargers, so that the system can keep a stable working condition, the higher refrigeration capacity is maintained, and the stability and the reliability of the refrigeration system are improved.

Description

technical field [0001] The invention relates to a Villemuir refrigeration device driven by exhaust heat of a fishing boat engine, in particular to a free-piston Villemuir refrigeration device. Background technique [0002] In recent years, my country's deep-water fishing industry has developed rapidly, and the internal combustion engine or engine of a fishing boat is one of the largest energy consumers as a means of marine transportation. Waste heat is directly discharged into the environment, causing huge energy waste. And for the pelagic fishing industry, fishing boats have to bring fuel, fresh water, ice, etc. when going out to sea, which is time-consuming and laborious, which reduces the effective utilization rate of the ship and makes it difficult to go out to sea. Therefore, effective measures must be taken to rationally utilize these waste heat in order to achieve the purpose of saving energy. [0003] The Villemier refrigerator uses the Stirling heat engine cycle an...
