Heat sink of concentrated photovoltaic power generation system based on chimney effect

Abstract

The invention discloses a chimney effect based radiator with a concentrating photovoltaic power generation system. The radiator comprises a chimney, a bottom plate, the concentrating photovoltaic power generation system and a radiating apparatus, wherein the bottom of the chimney is connected with the bottom plate through an L-shaped connecting part; the lower end of the connecting part is connected with the bottom plate while the upper end of the connecting part is connected with the chimney; the radiating apparatus comprises a hexahedral structure formed by fin structures in a fixed connection manner; the radiating apparatus is mounted in the chimney through a connecting part and positioned at the upper part of the chimney; the concentrating photovoltaic power generation system comprises a three-dimensional black body cavity and a solar cell panel; the three-dimensional black body cavity comprises a cylinder in the middle and conical bodies at the two ends; the solar cell panel is plated on the inner surface of the three-dimensional black body cavity; and the three-dimensional black body cavity is arranged in the hexahedral structure formed by the fin structures. By adoption of the chimney effect based radiator provided by the invention, the problems of bad circulation cooling effect, system electric energy consumption by forceful circulation cooling, relatively high initial investment for novel cooling technologies, high cost, and the like existing in the prior art can be solved.

Description

technical field [0001] The invention relates to a heat sink, in particular to a solar cell heat sink. Background technique [0002] As an inexhaustible energy source, solar energy has the advantages of cleanliness and environmental protection. It is estimated that the annual solar radiation energy received by the land surface is about 58×1019KJ, which is equivalent to the calorific value of 170 billion tons of standard coal. my country has very rich solar energy resources. The total annual solar radiation across the country reaches 3340-8400MJ / m2·a, the national annual average sunshine hours are 2200 hours, and the average solar power is 1700TW·h. The total amount of solar radiation in my country's northwest region, southwest region, southern Guangdong Province, Hainan Province and coastal islands is very large, and it has unique and superior resource conditions for the development and utilization of solar energy. Solar energy, as a renewable new energy source, has attract...
