Problems solved by technology
But the main problem of this kind of portable power supply is that it is noisy, and its noise index is 60 decibels (7 meters away), which is higher than the index of about 50 decibels that can be tolerated in normal work and life; the maintenance cycle is short, and the maintenance cost is high. It takes tens of hours to maintain spark plugs, fuel tanks, and fuel filters; the maintenance work is complex, including the need to clean and adjust spark plugs, fuel tanks, fuel filters, and valves, etc., which seriously restricts the application of portable power supplies

A portable silence power supply comprises a free piston Sterling power generator system, a burner system and a suspension system. The power generator system comprises a free piston Sterling engine, a linear motor, a damping device and a water circulation loop. External heat is absorbed by the heat end external heat exchanger of the engine and transmitted to working medium through a heat end internal heat exchanger, the heat is converted into acoustic work in a heat regenerator through the expansion heat absorption and compression heat discharge process of the working medium, the acoustic work is transmitted to a power piston through a discharger, and the power piston drives the rotor of the linear motor to cut a magnetic line so as to convert into electric energy output. The damping device is connected to the back cavity of the motor. The water circulation loop is connected to a room temperature end heat exchanger shell. The suspension system is columnar spring or a bow-shaped spring which is in suspension connection with the free piston Sterling power generator. The portable silence power supply is compact in structure, high in specific power, high in reliability, and the like.
Description
technical field [0001] The present invention relates to the field of power supply, in particular to a portable silent power generation system, which uses a free piston Stirling generator to convert the heat generated by a burner into stable power output, and makes the power supply have high reliability. Background technique [0002] Portable power supplies have a wide application base in outdoor sports, camping, field operations, islands and military, providing reliable and stable power for production and living equipment. Most of the current commercial portable power supplies use internal combustion engines to convert the heat generated by the combustion of gasoline or diesel into electrical energy. Compared with portable power sources such as batteries, this type of portable power source has the advantages of high energy density and convenient battery life. But the main problem of this kind of portable power supply is that it is noisy, and its noise index is 60 decibels ...
