Abstract

The invention discloses a solar cell panel temperature adjusting and controlling device, belonging to the field of photovoltaic cell panel temperature control. The solar cell panel temperature adjusting and controlling device is characterized in that a phase change material box body is welded and connected with a device shell, and a tempered glass plate is placed at the upper port of the device shell; two long side faces of the device shell are welded with outside radiating ribs; and a solar cell panel base plate is welded with the phase change material box body, an inside needle rib is welded on the solar cell panel base plate, and a phase change material and a thermal diode material are respectively injected into the temperature adjusting and controlling device by forming a heat storage material injection hole and a thermal diode material injection hole. The solar cell panel temperature adjusting and controlling device disclosed by the invention has the advantages that the heat transfer characteristic of a phase change heat storage material is strengthened, and the overall heat conducting property of the device is enhanced, so that the heat dissipation effect of a solar cell panel working under a high temperature condition is achieved, the normal working temperature of the solar cell panel is maintained, the service life of the solar cell panel is prevented from being shortened due to over temperature and heat, the generating efficiency can not be lowered, the influence of a low-temperature environment on the solar cell panel and the tempered glass plate is weakened, and the frost crack is prevented.

Description

technical field [0001] The invention belongs to the field of temperature control of photovoltaic panels, in particular to a temperature control device for solar panels. Background technique [0002] In recent years, with the reduction of fossil energy reserves and the increasingly serious environmental pollution caused by fossil energy, clean and sustainable renewable energy has been developed on a large scale. Among renewable energy, solar photovoltaic power generation is also in the energy structure. will occupy an increasing proportion. At present, the industry's most concerned issues about solar photovoltaic power generation are power generation efficiency and equipment life. The service life and power generation efficiency of solar panels are related to the working temperature. Excessively high temperature will seriously reduce the service life and power generation efficiency of solar panels. This effect is more significant in concentrating photovoltaic technology. Th...
