Problems solved by technology

Its advantage is that it integrates a generator, has a compact structure, and can burn solid fuels. However, the heat engine with this structure still has the following disadvantages: it basically adopts the traditional heat engine structure, and its structure is still relatively complicated and bulky. Such as two cylinders, regenerators, etc., the product is difficult to realize, and the production cost is high, it is not suitable for low power applications below 100W

Embodiment Construction

[0018] As shown in Figures 1, 2 and 3, it is an embodiment of the present invention. A cylindrical heater 1, a baffle plate 13, a cooler 4, a fuselage 11 and a bottom plate 10 are arranged on the outside in sequence from top to bottom, and a gas distribution piston is arranged in sequence from top to bottom inside the closed space formed by the above components. 2. Piston rod 3, power piston 5, connecting rods 6, 7, 8 and crankshaft 9 and other components. The heater 1 is a thin-walled cylindrical structure with a closed top, which is processed by heat-resistant metal, and is used to transfer the heat generated by the heating device of the heater to the working medium in the inner cavity, and push the piston to do work. The inner cavity of the heater 1 is adapted to the structure of the piston top 210 of the gas distributing piston 2 of the heater, and forms the gas distribution cylinder of the heater together with the cooler 4 inner cavity at the lower end. The heater 1 is s...

Abstract

This invention discloses one micro hot air engine, which comprises heater, regenerator, cooling device, curve shaft, machine shell, dynamic piston and pneumatic piston and one sealed curve shaft, wherein, the said pneumatic piston and dynamic piston are set by upper and down axis; down end of pneumatic piston is connected with piston bar through central hole of dynamic piston; cooling device is of ring cylinder structure with its top end connected to heater and down end connected to shell and with matching piston; the cooling hole and heater inner chamber form pneumatic cylinder with certain match gap.

Description

technical field [0001] The invention relates to a low-power heat engine, in particular to a small external combustion type heat engine. Background technique [0002] The heat engine, also known as the Stirling engine, is an external combustion engine heated by an external heat source. It is mainly composed of a heating system, a working medium circulation system, and a transmission system. Components and gas distribution piston components are the key parts that constitute the circulation system of the heat engine. The heat generated by the heating system is transferred to the internal working medium of the heat engine through the heater, and through the Stirling cycle, the piston is pushed to do work, and the heat is passed through the crankshaft of the transmission system. Or the output shaft is output externally. The regenerator is equivalent to an accumulator, which is used to absorb or release the heat of the working fluid in the Stirling cycle; the heater is used to he...
