Embodiment 1

[0034] Such as figure 2 As shown, the structure of Embodiment 1 of the regenerative heat engine performance testing device of the present invention mainly includes a compression motor (only its compression piston 1 is drawn in the figure), a regenerative heat engine (including the main radiator 2 connected in sequence, the regenerative 3, non-room temperature heat exchanger 4, heat buffer pipe 5 and secondary radiator 6), expansion motor (only its expansion piston 7 and expansion surface 8 and compression surface 9 are shown in the figure), dissipation mechanism and phase-locking power supply13. The expansion motor is different from the traditional motor: the traditional motor piston has only one end face to participate in the process of absorbing or outputting sound work. The compressor motor piston in the present embodiment has only that end face adjacent to the main radiator 2 to participate in the output process of the sound work, and the other end face has no practical ...

Embodiment 2

[0038] Such as image 3 As shown, in this embodiment, the core components of the regenerative heat engine only include the main radiator 2 , the regenerator 3 and the non-room temperature heat exchanger 4 . The expansion surface 8 of the expansion piston 7 is adjacent to the non-room temperature heat exchanger 4, and works under non-room temperature conditions, while the compression surface 9 of the expansion piston 7 works under room temperature conditions. The dissipation mechanism is an inertia tube 14, and the inertia tube 14 It is connected to the outer side of one end surface of the cylinder where the expansion motor is set. The sound work consumed by the inertia tube 14 is greater than the sound work absorbed by the expansion surface 8 of the expansion piston 7, so the expansion motor needs to input electric work and convert the electric work into mechanical energy in the form of sound waves. Therefore, this system can also adjust the phase relationship between the inp...

Embodiment 3

[0041] Such as Figure 4 As shown, the structure of the regenerative heat engine performance test device in this embodiment is the same as that of the traditional regenerative heat engine performance test device ( figure 1 ) similarly, the regenerative heat engine includes a main radiator 2, a regenerator 3, a non-room temperature heat exchanger 4, a thermal buffer pipe 5 and a secondary radiator 6 connected in sequence, but between the regenerative heat engine and the expansion motor piston A dissipating mechanism is installed, and the dissipating mechanism here is an inertia tube 14, and the inertia tube 14 is connected to the outer position of the cylinder block part between the regenerative heat engine and the expansion surface 8 of the expansion motor. Only one end surface of the expansion motor participates in the work, and the expansion surface 8 is opposite to the secondary radiator 6 and outputs sound work. The sound work consumed by the inertia tube 14 is greater th...

Abstract

The invention relates to the technical field of mechanical performance testing, in particular to a regenerative heat engine performance testing device. The regenerative heat engine performance testing device includes a compression motor, an expansion motor, a dissipating mechanism and a phase-locked power supply; the dissipating mechanism is connected on the cylinder body near the piston surface of the expansion motor to dissipate the sound output from the piston surface of the expansion motor. Because the sound work consumed by the dissipation mechanism is greater than the sound work absorbed by the expansion motor, the electric work is input into the expansion motor, and the expansion motor converts electrical energy into mechanical energy. Both the expansion motor and the compression motor need to consume electric work, and the expansion motor and the compression motor Both are connected to the phase-locked power supply, so the phase relationship between the two input currents can be adjusted through the phase-locked power supply, so that the movement of the compression piston and the expansion piston can reach a specific phase relationship, and realize the required sound field inside the regenerative heat engine.

Description

technical field [0001] The invention relates to the technical field of mechanical performance testing, in particular to a regenerative heat engine performance testing device. Background technique [0002] Generally, regenerative heat engines include Stirling heat engines (including engines, refrigerators and heat pumps), thermoacoustic heat engines (including engines, refrigerators and heat pumps), pulse tube refrigerators, etc., which use the reciprocating motion of gas and the compression and expansion process , realizing the conversion between thermal energy and mechanical energy is a very important way of thermal work conversion. In recent years, it has very important application prospects in solar power generation, superconducting cooling, and industrial waste heat utilization. [0003] Although there are many types of regenerative heat engines, they are only different in the way of phase modulation or the form of pressure wave generation, while the principle of heat po...
