Abstract

The invention provides a heating head heat exchanger of a solar Stirling engine and relates to a transduction component applied to a solar optothermal Stirling engine. The heating head heat exchanger is characterized by being composed of four heating head assemblies arranged in circular array, wherein the heating head assembly comprises a piston cavity, a back heating cavity, heating tubes and temperature sensors; each piston cavity and each back heating cavity are mounted on the engine by a relative phase angle of 90 degrees; N heating tubes are mounted between the piston cavity and the back heating cavity of each pair so that a solar light receiving curved surface formed by use of the N heating tubes arranged together can be formed; a plurality of temperature sensors are arranged in each piston cavity and on the heating tubes, respectively. The heating head heat exchanger of the solar Stirling engine has the characteristics of novel and simple structure, simple and convenient manufacturing, reduction of manufacturing difficulty, increase of yield, reduction of manufacturing cost and the like, and is a novel heating head heat exchanger integrated with economic efficiency and practicability.

Description

technical field [0001] The heating head heat exchanger of a solar Stirling engine according to the invention relates to an energy conversion component applied to a solar photothermal Stirling engine. Background technique [0002] The Stirling engine is a closed-cycle external combustion engine that is heated by external energy. It has the characteristics of a wide range of energy use, high conversion efficiency, stable operation, low or no pollution, and is the core technology and equipment for the development of green new energy. . In the development and utilization of solar energy and heat, the Stirling engine uses the high-temperature light and heat source generated by the large-scale butterfly-type spotlight tracking device to work, and converts it into mechanical energy to drive the generator through engine heat exchanger components, heat recovery and cooling energy conversion components, and piston mechanism Work. Stirling solar thermal power system has no combustion...
