Double-spherical solar concentrating cooker

Abstract

A double-spherical solar concentrating cooker consists of five big parts including a spherical solar concentrating cooker 1, a spherical heat collector 2, a heat superconducting pipe 3, a transparent thermal hood 4, and a superconducting heat exchanger 5. The defect in the prior art that as an irradiation angle varies with the movement of sunlight in four reasons and different periods in a day, great energy is lost during collection due to the change of the focus point of the solar cooker is overcome. Through the adoption of the inner and outer double-spherical design, sunlight irradiated from any direction and any angle can all be well focused, and generated great heat energy is accurately irradiated on the spherical heat collector. Meanwhile, through the additional arrangement of the thermal hood, the heat collection efficiency is largely increased.

Description

technical field [0001] The invention relates to a novel solar cooker, in particular to a double-spherical solar energy concentrating cooker designed as a spherical solar cooker with an inner and outer double-layer structure. Background technique [0002] Solar cookers belong to the medium and high temperature utilization field of solar thermal utilization technology, and the utilization efficiency of solar energy is relatively high. At present, most of the solar cookers widely used at home and abroad are arc-shaped and open small semicircular structures. As the angle of sunlight irradiates changes, the concentrating point will also move accordingly, which is very inconvenient to use. In the case of focusing, it is difficult to use all-weather. For this reason, people have designed a solar computer-controlled intelligent tracking solar cooker, which can track and position with the angle of sunlight irradiation, and rotate the entire solar cooker to keep the spot on the spot. ...

At present, most of the solar cookers widely used at home and abroad are arc-shaped and open small semicircular structures. As the angle of sunlight irradiates changes, the concentrating point will also move accordingly, which is very inconvenient to use. In the case of focusing, it is difficult to use all-weather. For this reason, people have designed a solar computer-controlled intelligent tracking solar cooker, which can track and position with the angle of sunlight irradiation, and rotate the entire solar cooker to keep the spot on the spot. On the energy harvester, improve the efficiency of photothermal energy collection

However, its cost of construction and long-distance travel are high, and it often breaks down, and it takes up a lot of space. This restricts the promotion and implementation of some places with limited space utilization and small environmental expansion range, and the cost of use increases greatly. , which is not conducive to the large-scale promotion and use of solar thermal technology, and restricts the development of renewable energy technology
