By improving the combustion air introduction path, the working gas consisting of horns or a mixture thereof is passed between the expansion chamber, which is a high temperature section, and the compression chamber, which is a low temperature section, via a heater, a heat storage device, and a cooler 2. It moves back and forth to extract mechanical work to the outside. Maintaining the temperatures of the high temperature section and the low temperature section at predetermined values is important for stabilizing the output of the Stirling engine. For example, heat leakage from the high-temperature section to the low-temperature section through the walls of the cylinder that forms the expansion and compression chambers lowers the temperature of the high-temperature section and increases the temperature of the low-temperature section, causing a reduction in the output of the Stirling engine. It becomes. Furthermore, the leaked heat is released to the atmosphere through the radiator, reducing the thermal efficiency of the engine.

A cooler block 6 is arranged around the compression chamber 5. Cooling water 1 is caused to flow into cooler block 6. The good heat collected in the cooling water 7 is

It has an air preheater 9 around it and a fuel atomizer 10 in the center of the top. A heat insulator 11 is provided at the bottom of the combustor 8, and a heater 14 communicating with the expansion chamber 4 and the heat storage device 13 is arranged within the combustion chamber 12. The heater 14 receives the combustion heat, heats up the working gas therein, supplies it to the expansion chamber 4 , and also functions to recover the working gas from the expansion chamber 4 to the heat storage device 13 . The heat accumulator 13 is communicated via a cooler 215 with cooling water 7 to the compression chamber 5 of the adjacent cylinder.

とができる。In the above-described configuration, combustion air is introduced from below into the cooler block 6, enters the combustion air introduction passage 16 through the central inlet 18 of the cooler block 6, and flows uniformly outward in the radial direction p1. At this time, since a part of the cylinder 2 is exposed to the air introduction passage 16, even if the high temperature of the combustion chamber 12 is transmitted through the wall of the cylinder 2, this heat is
The combustion air in the air introduction passage 16 is recovered and the cylinder 2
Heat transfer to the compression chamber 5, which is on the low temperature side, is minimized. Furthermore, this heat recovery by air reduces the burden on the air preheater 9 around the combustion chamber 12, and also reduces heat transfer to the cooling water 7, making it possible to downsize the heat dissipation section of the cooler 15. 4 From the perspective of practical soil, since an air layer with a high heat insulation effect is formed between the combustor 8 and the cooler block 6, heat transfer due to radiation from the combustor 8 side to the cooler block 6 is reduced. , the temperature rise of the cooler block 6 can be suppressed to a minimum.

使える。As is clear from the above, according to the present invention, a combustion air introduction path is formed between the heat insulator at the bottom of the combustor and the cooler block facing it, and the combustion air is introduced from the center of the cooler block. The heat that leaks from the hot section to the cold section through the cylinder wall is absorbed by the air inlet, flows radially outward, and then into the air preheater around the combustor. It can be recovered by combustion air on the road. This improves the output and thermal efficiency of the Stirling engine, reduces the burden on the air preheater, and contributes to downsizing of the heat dissipation section of the cooler. Furthermore, since the air from the air introduction passage uniformly enters the preheater, the entire heat transfer area of the preheater can be used effectively.
