For the photovoltaic radiator be applied in solar cell, existing radiator can be provided with radiating fin with increasing heat radiation area on base plate of radiator, but existing radiator is array distribution, and heat is suitably dissipation still, and radiating effect is still not good.The radiator simultaneously also had, its be by welding manner by radiating fin and radiating bottom plate seam, the solder side between radiating fin and radiating bottom plate also can increase and decrease thermal-conduction resistance like this, also is difficult to meet high heat conducting demand.How further improving heat dispersion and the radiating efficiency of radiator, is problem to be solved in the utility model.
The utility model content
The purpose of this utility model is to provide a kind of photovoltaic heat spreader structures, and it can improve the heat dispersion of radiator greatly, and cost-saved.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of photovoltaic heat spreader structures, it includes base plate, radiating core and multi-disc radiating fin, be distributed with screwed hole on radiating bottom plate, radiating core is positioned at the lower surface center of base plate, radiating fin is radiation and is distributed on the surface of radiating core, and the outer surface of radiating fin and the lower surface of base plate all form has the male and fomale(M&F) structure that increases external surface area.
The outer surface of described radiating fin and the lower surface of base plate form zigzag, and the sawtooth straight line is evenly distributed on the outer surface of radiating fin.
The outer surface of described radiating fin and the lower surface of base plate are scalariform or undulate curved-surface structure.
Described base plate lower surface is certain gradient, and forms boss on both sides, and screwed hole is arranged on boss.
Described radiating core is arcuation or semicircle shape.
Described radiating fin one-shot forming, on radiating core, forms circular arc at root between adjacent radiating fin.
After adopting said structure, radiator of the present utility model, one-body moldedly on the radiating core of base plate of radiator go out radiating fin, and the radial distribution of radiating fin is more conducive to hot-air and flows to increase heat-dissipating space.Further, the outer surface of radiating fin forms has the long-pending male and fomale(M&F) structure of the outer face surface of increase, thereby can greatly increase area of dissipation and convection current performance, and its processing technology is simple, by the extrusion die one-shot forming, can realize, compared to traditional fin slices radiator, its area of dissipation, much larger than the radiator outer surface not being made the radiator of any processing, also can improve preferably heat dispersion in the cost situation

Embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Photovoltaic radiator of the present utility model mainly is applied in the heat radiation of solar cell, it is arranged on the concentration photovoltaic system base plate, being used for is electric energy by the transform light energy of solar energy, concentrator cell in solar receiver is converted to direct current by solar energy, the heat energy that the part sunlight is converted to dispels the heat to air by radiator, thereby effectively reduce battery temperature, the lower end of radiator is exposed in the environment of concentration photovoltaic system outside, thus the work calories that solar cell produces via heat sink radiates to external environment condition.
In conjunction with shown in Fig. 1 to Fig. 4, photovoltaic radiator of the present utility model includes base plate 1, radiating core 2 and multi-disc radiating fin 3, wherein, base plate 1 is plane, be distributed with the screwed hole 11 that connects location use on base plate, thereby radiator can be connected on the assembly of solar modules, as be connected to solar modules casing below, be fixed with solar cell on base plate plane.Radiating core 2 is positioned at the lower surface center of base plate 1, and radiating core 2 is arcuation, or is semicircle shape, radiating fin 3 evenly extends and stretches out on the surface of radiating core 2, radially distributes, and radiating fin 3 can be by the extrusion die one-shot forming on radiating core 2, without being installed separately, technique is simple.Heat conducts on radiating fin 3 by radiating core 2, radiator fins 3 is the aerofoil profile certain angle and evenly opens, below radiating core 2, launch to extend, the gapped distribution of radiating fin 3 when increasing the area of dissipation of radiating fin, also increase heat-dissipating space when increasing radiating fin 3 area of dissipation, be more conducive to hot-air and flow.Form circular arc at root between simultaneously adjacent radiating fin 3, can increase the arc radius 31 of radiating fin 3 at root, to increase the heat dissipation region of radiating core 2, slightly improve heat dispersion.Further, can make base plate 1 lower surface be certain gradient, thereby the thickness at the dual-side place thickens some and forms two boss 12, screwed hole 11 can be arranged on boss 12, thereby increase screwed hole 11 place's degree of depth, boss 12, to forming an interior concave space between radiating core 2, can reduce material usage, saves material cost.
Important improvement part of the present utility model is, in the utility model, the outer surface of radiating fin 3 forms has concavo-convex nonplanar structure, thereby increase the exterior surface area of heat radiation, as shown, can be spiculation 32 in the outer surface setting of radiating fin 3 and arrange, and the sawtooth straight line is evenly distributed on the surface of radiating fin, the surface of radiating fin 3 forms the concavo-convex surface of indentation, thereby has greatly increased the external surface area of radiating fin 3.Certainly, the outer surface of radiating fin 3 also can be ladder-shaper structure, or waveform curved-surface structure, or directly being set to male and fomale(M&F) etc. can increase the nonplanar structure of surface area, thereby can increase area of dissipation and convection current performance, and its processing technology is simple, by the extrusion die one-shot forming, can realize, compared to traditional fin slices radiator, its area of dissipation, much larger than the radiator outer surface not being made the radiator of any processing, also can improve preferably heat dispersion in the cost situation.The lower surface of base plate of radiator 1 also is set to nonplanar structure simultaneously, synchronously to increase the radiator heat-dissipation performance, as shown in Figure 4, between radiating core 2 and boss 12, together with the surface to boss 12, also is set to hackly surface.
