Abstract

The invention relates to a heat dissipation system applied to a light-concentrating solar panel. A low-temperature Stirling engine distributing cylinder is directly contacted with a back side of a solar panel; a gas moving piston is arranged in the distributing cylinder; a power cylinder is arranged on the distributing cylinder; a power piston is arranged in the power cylinder; and the gas moving piston is connected with the power piston through a crank connecting rod. The tail end of the crank connecting rod is connected with a bull gear of a conical gear and thus a pinion of the conical gear is driven to make rotations, so that a fan is driven. And the conical pinion is connected on a tracking support of a photovoltaic array through one end of a rotating shaft support; and the other end is connected with a rotating shaft of the fan. According to the invention, heat of a solar panel is used to drive a piston to make movements and the movements are converted into power to drive a fan to make rotations to carry out heat dissipation on the solar panel. The heat dissipation system has characteristics of reasonable design structure, fast heat conduction diffusion, good uniform heat dissipation and compact structure. And the system is especially suitable for heat dissipation of a solar panel in a light-concentrating photovoltaic system.

Description

technical field [0001] The invention relates to a solar energy utilization technology, in particular to a heat dissipation system of a Stirling engine applied to a solar battery panel of a concentrated photovoltaic system. Background technique [0002] With the increasing publicity of energy conservation and emission reduction in our country at this stage, solar energy, as a clean and renewable energy source, has been vigorously promoted and widely used in different regions and fields in our country. [0003] At present, the research on improving solar energy efficiency mainly focuses on optimizing the structure of equipment and developing new materials. Although the conversion efficiency of photovoltaic light and heat has been improved to a certain extent, the benefit effect is not obvious due to the huge amount of investment. The impact of high solar panel temperature on system efficiency, as the most direct factor, severely limits the performance of solar energy and indir...
