Abstract
The invention discloses a heat dissipation device for a liquid-immersed solar cell. The heat dissipation device comprises a transparent cover plate, two side walls, a solar cell, a metal substrate and insulating liquid, wherein the transparent cover plate, the two side walls and the metal substrate form an insulating liquid flow passage, in which the insulating liquid is contained; the solar cell is fixedly arranged on a light receiving surface of the metal substrate; and fins are arranged on the back of the metal substrate. The heat dissipation device can effectively cool the front and the back of the solar cell at the same time and immediately carry away the heat produced during the work of the solar cell so as to maintain high-efficiency work of the solar cell, prolong the life of the cell and reduce the cost.
Description
Technical field
The present invention relates to a kind of heat abstractor of liquid-immersed solar cell, belong to the concentrating photovoltaic power generation technical field.
Background technology
In the light gathering photovoltaic power generating system, owing to adopted than common solar cell more high efficiency concentrator solar cell being arranged, therefore is one of effective way that reduces the solar photovoltaic generating cost.Yet solar cell is operated under the high light intensity condition, and the rising of battery operated temperature can cause the decline of efficient, therefore needs reliable cooling system and in time the heat that battery surface produces is taken away, and keeps the efficiency operation of solar cell.Existing cooling technology mainly contains passive type cooling and active cooling dual mode, yet the radiator that these two kinds of types of cooling all can only be by being arranged on cell backside falls the heat dissipation of solar cell, can't be simultaneously the front and back of battery component be effectively cooled off, solar cell is operated under the very high temperature, has reduced the efficient of light gathering photovoltaic power generating system.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of heat abstractor of liquid-immersed solar cell is provided.
Technical scheme of the present invention is summarized as follows:
A kind of heat abstractor of liquid-immersed solar cell, comprise transparent cover plate, two sidewalls, solar cell, metal substrate and iknsulating liquids, transparent cover plate, two sidewalls and metal substrate are formed the iknsulating liquid runner, be provided with iknsulating liquid in the iknsulating liquid runner, solar cell is fixedly installed on the sensitive surface of metal substrate, and the back side of metal substrate is provided with fin.
The shape of metal substrate can select rectangle also can select shape geometric similarity with concentrator.
The height of iknsulating liquid runner is 1mm～50mm.
The heat abstractor of a kind of liquid-immersed solar cell of the present invention, the front of solar cell directly contacts with the iknsulating liquid that flows, and the back side of solar cell is fixed on the metal substrate that has fin, therefore can be simultaneously the front and back of solar cell be effectively cooled off, the heat that solar cell work produces in time is pulled away, keep the efficiency operation of solar cell, extend the life of a cell, reduced cost.

Fig. 1 is the vertical view of first kind of structure of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The cutaway view of second kind of execution mode of Fig. 3 the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
A kind of heat abstractor of liquid-immersed solar cell, comprise transparent cover plate 1, two sidewalls 2, solar cell 3, metal substrate 5 and iknsulating liquids 4, transparent cover plate, two sidewalls and metal substrate are formed iknsulating liquid runner 7, be provided with iknsulating liquid in the iknsulating liquid runner, solar cell is fixedly installed on the sensitive surface of metal substrate, and the back side of metal substrate is provided with fin 6.
The shape of metal substrate can select rectangle also can select shape geometric similarity with concentrator, for example when concentrator is slot-type optical collector, the shape of metal substrate can be rectangle, it also can be groove type paraboloid, when concentrator is dish formula concentrator, the shape of metal substrate can be rectangle, also can be dish formula parabola.
The height h of iknsulating liquid runner can select between 1mm～50mm.
Transparent cover plate can be the plane, also can be curved surface.
Two sidewalls can be made by transparent material and also can select opaque material to make.
Solar cell can by glued, welding or mechanical connection manner be fixed to metal substrate sensitive surface.
Being arranged on the fin at the metal substrate back side, can be one with metal substrate, also can be the back side that is fixed to metal substrate by gluing, welding or mechanical connection manner.
