Utility model content
The purpose of this utility model 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 purpose of this utility model is achieved in that 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.
Improve as one of the present utility model, flat heat pipe radiator size at least is in one direction greater than the size of described radiating surface in this direction.
As further improvement of the utility model, 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 utility model, the quantity of the flat heat pipe radiator of described elongate in shape is plural number again.
Improve further again as of the present utility model, 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 utility model, 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 utility model 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.
