Abstract

The utility model relates to a cooling device for a solar cell, which is low in cost, is suitable for quickly cooling the temperature of the solar cell and can be used for utilizing heat energy. The cooling device comprises a sealed metal heat dissipating cavity, a cooling liquid inlet, a cooling liquid outlet and a plurality of cooling fins, wherein the cooling liquid inlet and the cooling liquid outlet are respectively arranged at two ends of the metal heat dissipating cavity; the cooling fins are arranged in the metal heat dissipating cavity; the solar cell is arranged on a lower side face of a bottom plate of the metal heat dissipating cavity, and the cooling fins are respectively arranged in parallel on the bottom plate at intervals; the cooling liquid inlet is arranged to be adjacent to the top ends of the cooling fins, and the cooling liquid outlet is arranged to be adjacent to the bottom ends of the cooling fins; and as the bottom parts of the cooling fins have higher temperature, liquid can flow from top to bottom to realize gradual temperature rise so as to ensure heat exchange efficiency when cooling liquid is delivered from the cooling liquid inlet to the cavity, wherein the cooling liquid inlet is higher than the cavity in position. When the cooling device is adopted, materials are saved, and heat of the cooling liquid can be utilized directly or secondarily at interval.

Description

The used for solar batteries cooling device

Technical field

The utility model relates to a kind of used for solar batteries cooling device.

Background technology

When adopting concentrator and solar cell to carry out opto-electronic conversion,, cause the solar cell temperature higher, thereby influence the useful life of photoelectric conversion efficiency and solar cell because sunray intensity is bigger.

Therefore, how to provide a kind of simple and reliable for structure, with low cost, be suitable for quick cools solar cell temperature and realize heat energy utilization, be the technical problem that this area will solve.

Summary of the invention

The technical problem that the utility model will solve provide a kind of simple and reliable for structure, with low cost, with low cost, be suitable for quick cools solar cell temperature and realize the used for solar batteries cooling device of heat energy utilization.

For solving the problems of the technologies described above; The used for solar batteries cooling device that the utility model provides comprises: the heat dissipation metal cavity of sealing, be located at cooling fluid inlet and cooling liquid outlet and a plurality of fin of being located in the heat dissipation metal cavity at heat dissipation metal cavity two ends respectively; The downside of the base plate of heat dissipation metal cavity is used to be provided with solar cell, parallel alternate being located on the said base plate of each fin, and the angle of fin (13) and said base plate (14) is an acute angle; The top of the contiguous said fin of cooling fluid inlet is provided with, and the bottom of the contiguous said fin of cooling liquid outlet is provided with; Because the fin bottom temp is higher, when the cooling fluid cooling fluid inlet higher from the position sent into cavity, liquid is flowed and progressively intensification from top to bottom, guarantee heat exchange efficiency.

Further, the projection section of adjacent fin on said base plate overlaps, so that the abundant heat exchange of fin and cooling fluid.

Further, has the gap between the top board of said fin and heat dissipation metal cavity, so that the cold and hot abundant convection current of cooling fluid and it is heated evenly.

Further, the downside of the base plate of heat dissipation metal cavity is provided with rectangular recess or the boss that is used to be provided with solar cell, to make things convenient for the installation of solar cell.

The technique effect that the utlity model has: the used for solar batteries cooling device of the utility model, to economize with material, the heat of cooling fluid can directly utilize or the gap second use.Cooling fluid can be water, oil or other medium.When utilizing water to cool off, its ambient temperature is lower than when subzero, can integral heat dissipation means vertically be provided with; Automatically close into Shui Chu, adopt the pump of being located at delivery port to extract a part of water out, reserve enough spaces to heat-dissipating cavity; Even water freezing, volumetric expansion can be with the cavity bursting by freezing yet.When the temperature fast rise, through program control, the system by programed temperature detects accelerates water velocity in the chamber, immediately with rapid heat radiation.Adopt step motor drive high temperature diaphragm pump, adopt temperature detection and control simultaneously.The control temperature can be provided with flexible operating.
