Description
Technical field
The utility model relates to Photospot solar technical field more particularly to a kind of Photospot solar receiver and heat dissipations
Device integral structure.
Background technique
Currently, intermediate medium generally uses when most of high concentration solar receiver is combined with thermal component
Be to apply the mode of thermal paste of scraping.Since thermal paste is originally experienced the influence of the factors such as thermal coefficient and thickness, the heat of generation is not
It can be conducted to radiator in time, solar battery chip junction temperature meeting rapid increase makes solar battery chip generating efficiency significantly
It reduces.Solar battery chip is not suitable for long-term work under more than 100 DEG C high temperature, easy to aging to make reduced performance, or even damage
Solar battery chip；Current loss excessive (electric leakage) and open-circuit voltage (Voc) is also resulted in increase and reduced with temperature
It is more, it is reduced so as to cause final power output and generated energy.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of Photospot solar receiver and heat dissipation are provided
Device integral structure.
The technical solution of the utility model is as follows: providing a kind of Photospot solar receiver and radiator integrated knot
Structure, comprising: radiator and several receivers set on the spreader surface.It is equipped between the radiator and the receiver
The first metal layer and several second metal layers, the receiver is close by welding, seamless is welded on institute
State spreader surface.
The Facing material of the radiator is one of copper, aluminum, aluminium copper or high-speed steel.
The first metal layer is one of zinc, nickel, silver, gold, chromium.
The first metal layer is generated using electrochemical method in the spreader surface.
The second metal layer is high thermal conductivity tin cream.
The second metal layer is two layers, and the second metal layer is overlying on first metal respectively by way of printing
Layer upper surface and the receiver lower surface.
Welding manner between the radiator and the receiver uses reflow soldering process.
Using the above scheme, the utility model receiver and radiator integrated structure are realized integrally by welding manner
Change, simple process and low cost.Compared to conventional coupling arrangement, face of weld can be made by increasing thermally conductive tin cream using metal protection layer
It is seamless, in conjunction with closer, bonding strength height；Tin cream thermal resistance is low simultaneously, and radiating efficiency 30% can be improved, reliable and stable；Power
Loss is few, and generating efficiency is high；Receiver service life extends.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model receiver and radiator integrated structure.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, the utility model provides a kind of Photospot solar receiver and radiator integrated structure, packet
It includes: radiator 1 and several receivers 2 set on 1 surface of radiator.The receiver logical 2 is close by welding
, seamless be welded on 1 surface of radiator.The Facing material of the radiator 1 be copper, aluminum, aluminium copper or
One of high-speed steel, the surface using the excellent metal material of heating conduction as the radiator 1, can play good
Thermal diffusivity prevents 2 temperature of receiver excessively high.Between the radiator 1 and the receiver 2 be equipped with the first metal layer and
Several second metal layers.The first metal layer is one of zinc, nickel, silver, gold, chromium.The first metal layer is using electrification
Method is created on 1 surface of radiator, this layer of metal layer can play the role of the protection spreader surface, prevent
The heat spreader metals surface oxidation, while increasing welding performance.The second metal layer is two layers, and the second metal layer is logical
The mode for crossing printing is overlying on 2 lower surface of the first metal layer upper surface and the receiver respectively, and the second metal layer is
The thermal resistance of high thermal conductivity tin cream, tin cream is low, and heating conduction is excellent, and tin cream good welding performance, two for respectively welding needs
Upper high thermal conductivity tin cream is printed in face, and can reach good welds effect improves weld strength, reliability enhancing, while reducing heat
Resistance improves heat transfer efficiency, reduces power loss, improves generating efficiency.Welding between the radiator 1 and the receiver 2
Mode use reflow soldering process, solder reflow techniques temperature is easily controllable, be avoided that in welding process welding assembly aoxidize, manufacture at
Originally it is also easier to control.
In conclusion the utility model receiver and radiator integrated structure realize integration, work by welding manner
Skill is simple, at low cost.Compared to conventional coupling arrangement, increasing thermally conductive tin cream using metal protection layer can make face of weld seamless
Gap, in conjunction with closer, bonding strength height；Tin cream thermal resistance is low simultaneously, and radiating efficiency 30% can be improved, reliable and stable；Power loss
Few, generating efficiency is high；Receiver service life extends.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
