Integral combined-type heat absorber of solar thermomotor

Abstract

The invention discloses an integral combined-type heat absorber of a solar thermomotor, wherein the heat absorber is provided with a plurality of fluid channels, fluid inlets and fluid outlets; the plurality of fluid channels are formed in a heat absorber body; the fluid inlets and the fluid outlets are formed on the surface of the heat absorber body and are respectively and correspondingly communicated with ports of two ends of each fluid channel in the heat absorber body; the fluid inlets are connected with an air cylinder through a connecting pipeline; the fluid outlets are connected with a heat regenerator through a connecting pipeline; the outer surface of the heat absorber body is a plane or a corrugated plane; the plurality of fluid channels in the heat absorber body and the heat absorber body are formed by integral casting; the heat absorber body is formed by the welding of two symmetrical plate bodies up and down; and the plurality of fluid channels are formed by the butt joint of symmetrical semi-round channel grooves on opposite surfaces of the two plate bodies which are symmetrical up and down. According to the invention, the heat absorber of the thermomotor is designed into a round integral combined-type heat absorber, or a circle is spliced by four fan-shaped objects of 90 degrees, thus solar condensation radiation heat is absorbed, the appearance is simple, the processing technology is reliable, mass production is convenient, and the cost is low.

Description

technical field [0001] The invention relates to a heat absorbing device for a solar heat machine. In particular, it relates to an integral combined heat absorber of a solar heat engine capable of effectively absorbing the concentrated radiant heat of the sun. Background technique [0002] The heat absorber is one of the important components of the solar heat engine (also known as the solar Stirling engine). Its heat transfer effect and ability to withstand high temperature and high pressure have a direct and significant impact on energy conversion efficiency, overall machine output and work reliability. Generally, for the consideration of high temperature and high pressure resistance, the heat absorber of a solar heat generator is mostly composed of densely arranged small-diameter pipes. Due to the limitation of pipe layout, the heat absorber of this structure has to design a round hole in the center, which is used to place a heat protection cone that does not directly abs...

AI Technical Summary

Problems solved by technology

Due to the limitation of pipe layout, the heat absorber of this structure has to design a round hole in the center, which is used to place a heat protection cone that does not directly absorb heat, which directly brings disadvantages to the heat absorption effect. influences

At the same time, since the circumference of the outer ring of the circular heater becomes larger, the distance between the tubes is closer at the center of the circle, and there will be a certain distance away from the center of the circle, so there will inevitably be gaps, which will definitely have a negative impact on the absorption of solar radiation energy. certain loss

In addition, the complex shape of many thin tubes of various shapes brings high technical difficulty to the processing technology, as well as problems such as more processing man-hours and higher mold costs.
