The invention discloses a thermal insulation pneumatic piston of a Stirling motor. The thermal insulation pneumatic piston comprises an outer shell, multiple thermal insulation sheets, an aluminum support, an aluminum bar and a movable connecting rod. The thermal insulation pneumatic piston of the Stirling motor is characterized in that the aluminum bar is inserted into a hole of the aluminum support, the movable connecting rod penetrates through the aluminum bar and is connected with the aluminum support, the outer side of the aluminum support is further wrapped with a resign layer, the multiple thermal insulation sheets are overlapped as a whole to form a thermal insulation sheet set, the thermal insulation sheet set is arranged in the outer shell, each thermal insulation sheet is provided with a hole, and a hole is formed in the top of the outer shell. By the adoption of the thermal insulation pneumatic piston of the Stirling motor, the six thermal insulation sheets are adopted, vacuumizing is carried out through the holes, and vacuumized portions are filled with helium, influences of external air on the inner portion of the Stirling motor can be isolated better, the heat insulation effect of the Stirling motor can be more ideal, and the refrigeration effect of a Stirling refrigerator can be further improved.
Description
technical field [0001] The invention relates to a heat insulation device, in particular to a heat insulation pneumatic piston of a Stirling motor. Background technique [0002] The Stirling motor is a type that can directly convert the thermal energy generated by solar energy into electrical energy, and can directly integrate the converted electrical energy into the grid to realize the rapid grid integration of solar power generation. In recent years, due to the continuous maturity of Stirling motor technology, the solar power generation industry using Stirling motors has also gradually heated up, making solar thermal power generation gradually warming up. However, because the Stirling motor works at high temperature for a long time and relies on the temperature difference between the high and low temperature ends of the motor, the current Stirling motor is not very mature in heat insulation technology, which affects the overall efficiency of the Stirling motor. . Therefor...
