Description
Technical field
The utility model relates to lighting field, is specifically related to a kind of cooling plate structure of LED street lamp.
Background technology
Street lamp is the important component part of city illumination, because the advantage such as that high-power LED street lamp has is energy-efficient, life-span length, environmental protection, so, be used in the street lighting of different kinds of roads.But the great power LED street lamp is after heating, and the brightness meeting obviously descends, and temperature is to also having a significant impact its service life, so the radiating effect of high-power LED street lamp has directly affected the extensive use of LED street lamp.Adopting maximum radiating modes at present is the conducting strip radiating mode, but the arrangement mode of common heat-conducting plate only has a direction, and radiating efficiency is not high, and mass ratio is larger, has increased lamp holder weight, has increased the danger coefficient of street lamp.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of cooling plate structure is provided, can improve radiating efficiency, also can reduce own wt simultaneously.
Technical solution adopted in the utility model is:
A kind of LED road lamp cooling plate structure, comprise heat-radiating substrate, also comprise vertical heat-conducting plate or horizontal heat-conducting plate that the heat-radiating substrate upper surface is provided with, described heat-radiating substrate upper surface is provided with vertical heat-conducting plate and the horizontal heat-conducting plate that intersects in length and breadth, and the surrounding section of heat-radiating substrate is provided with leaking hole.
The further improvement project of the utility model is, described leaking hole be located in the interval of vertical heat-conducting plate and horizontal heat-conducting plate.
The utility model further improvement project is that described leaking hole is located at vertical heat-conducting plate and is positioned at heat-radiating substrate periphery 2 to 4 row intervals with horizontal heat-conducting plate.
The utility model further improvement project is that described heat-radiating substrate upper surface is inverted V-shape.
The utility model further improvement project is that described V-shape angle spends 175 to the degree scope 170.
The utility model further improvement project is, on the heat-radiating substrate of the leaking hole middle part of surrounding section, except the horizontal heat-conducting plate C that is positioned at the inverted V-shape summit, all the other horizontal heat-conducting plates intersect with vertical heat-conducting plate compartment of terrain.
The utility model further improvement project is, the setting of staggering of adjacent transverse heat-conducting plate and vertical heat-conducting plate crossover location.
The beneficial effects of the utility model are:
When dispelling the heat with the utility model radiator structure, the heat-radiating substrate upper surface be provided with cross one another horizontal heat-conducting plate and vertically heat-conducting plate both increased area of dissipation, how heat-conducting plate can carry out the efficiently radiates heat heat radiation no matter to guarantee again wind direction; Upper surface of base plate has certain gradient, simultaneously is provided with leaking hole in heat-radiating substrate surrounding section, when having alleviated own wt, again can be when sleety weather, and make sleet dirty and take away heat fast.From the above-mentioned course of work as can be known, when dispelling the heat with the utility model, both improve radiating efficiency, and can alleviate again the own wt of heat sink.
