Background technology
Along with people are to the growth of clean energy resource demand, solar energy generation technology is more and more subject to people's attention.The conventional means of solar power generation be utilize such as crystalline silicon solar cell piece generating main body be electric energy by light energy conversion, and then by circuit by power delivery to electrical network or storage battery, i.e. so-called photovoltaic solar generation technology.In foregoing circuit, terminal box is very crucial parts.Existing photovoltaic solar terminal box is easily-consumed products, usually uses and will scrap for about 1 year, and in box, electronic component can produce a large amount of heat under operating state to cause the main cause of scrapping to be, thus causes the life-span greatly to shorten.In order to improve the radiating efficiency of photovoltaic solar terminal box, thus improve its useful life, some manufacturers have employed terminal block housings prepared by aluminum alloy materials, although the heat dispersion of this way butted line box makes moderate progress, but be electronic component due to what install in photovoltaic solar terminal box, need during production to do it insulate, heat insulation process, therefore the actual radiating effect of this solution still can not meet the demands far away, also can raise because of temperature in box in work, reduce the life-span of terminal box.
Summary of the invention
Object of the present invention is exactly the photovoltaic solar terminal box that will provide a kind of improvement, it can effectively solve existing photovoltaic solar terminal box in working order in box heat be not easy the problem left, useful life is short.
The object of the present invention is achieved like this: a kind of photovoltaic solar terminal box, comprise radiating surface, described radiating surface is fitted with flat heat pipe radiator, the part that flat heat pipe radiator contacts with the radiating surface of photovoltaic solar terminal box is the heat absorbing part of flat heat pipe radiator, and remainder is radiator portion.
As a modification of the present invention, flat heat pipe radiator size at least is in one direction greater than the size of described radiating surface in this direction.
As a further improvement on the present invention, described flat heat pipe radiator is elongate in shape, and the size of flat heat pipe radiator length direction is greater than the size of described radiating surface in this direction.
Improve further as of the present invention, the quantity of the flat heat pipe radiator of described elongate in shape is plural number again.
Improve further again as of the present invention, described flat heat pipe radiator is the radiator that inside is arranged side by side multiple independent heat pipe.
Described flat heat pipe radiator at least exceeds radiating surface size on radiating surface direction.
Improve as another kind of the present invention, fin is set in the outer end side surface of the flat heat pipe radiator exceeding radiating surface size.
Described flat heat pipe radiator covers whole radiating surface, and at least on a direction of radiating surface, exceeds radiating surface size, and flat heat pipe radiator 2 and terminal box 1 connection jaws correspondence position have corresponding aperture 4 below, and corresponding aperture 4 periphery arranges insulating case.
The present invention owing to being provided with flat heat pipe radiator on the radiating surface of photovoltaic solar terminal box; flat-plate heat pipe utilizes phase-change heat principle; there is the radiating efficiency higher than aluminum alloy materials; add that itself and heating surface fit tightly; thus the heat on photovoltaic solar terminal box radiating surface can be taken away rapidly; greatly can reduce the temperature of photovoltaic solar terminal box radiating surface, thus prevent that terminal box is overheated, electronic component in protection box, extend terminal box useful life.
