Description
Technical field
The present invention relates to LED road lamp cooling technical field, be specifically related to a kind of heat sinking LED street lamp module radiator.
Technical background
The fine aluminium radiator is early stage the most common radiator, and its manufacturing process is simple, and cost is low, and up to the present, the fine aluminium radiator is still in occupation of quite a few market.For increasing the area of dissipation of its fin, the most frequently used manufacturing process of fine aluminium radiator is the aluminium extrusion technology, and the leading indicator of estimating a fine aluminium radiator is the thickness and the Pin-Fin ratio of foot of radiator.Pin is meant the height of the fin of fin, and Fin is meant the distance between two pieces of adjacent fins.Pin-Fin than be height (not containing base thickness) with Pin divided by Fin, Pin-Fin means that than big more the efficiently radiates heat area of radiator is big more, represents the aluminium extrusion technology advanced more.
The coefficient of heat conduction of copper is 1.69 times of aluminium, so under the identical prerequisite of other conditions, the fine copper radiator can be taken away heat quickly from thermal source.But copper also has significant disadvantages, the cost height, and difficult processing, heatsink mass have too mostly hindered the application of full copper radiating rib.The hardness of red metal is not as aluminium alloy AL6063, and some machining (as profile groove etc.) performance is not as aluminium; The fusing point of copper is high more a lot of than aluminium, is unfavorable for extrusion molding (Extrusion) or the like problem.
Though at present the most frequently used fin material is copper and aluminium alloy, aluminium alloy is processed easily, and cost is low, is to use maximum materials, and the higher coefficient of heat conduction of copper, makes its heat absorption capacity better than aluminium alloy moment, and the speed of heat radiation is just wanted slowly than aluminium alloy.Therefore, no matter fine copper, fine aluminium, still aluminium alloy heat radiator, a fatal defective is all arranged: owing to only use a kind of material, though basic heat-sinking capability can satisfy the needs of slight heat radiation, but because can't balanced well capacity of heat transmission and the requirement of two aspects of thermal capacity ability, just some be unable to do what one wishes rather for the occasion of having relatively high expectations in heat radiation.
To this, the present invention proposes a kind of new heat dissipation technology-copper aluminium combination technology LED street lamp module radiator.
Summary of the invention
The present invention proposes a kind of heat sinking LED street lamp module radiator, mainly be to add heat conduction copper post (2) on the heat-dissipating casing (1) by the heat radiation module heat is derived, be connected on the heronsbill radiator (3), to cause the heat on the LED lamp pearl to be transmitted on the heronsbill radiator (3) at a high speed, distribute then by heat conduction copper post (2).
In order to realize the object of the invention, the technical scheme of employing is: a kind of heat sinking LED street lamp module radiator comprises heat radiation aluminium shell (1), heat conduction copper post (2), heronsbill radiator (3); Described heat radiation aluminium shell (1) becomes interference fit with heat conduction copper post (2); Described heronsbill radiator (3) passes through threaded engagement with heat conduction copper post (2); Described heat radiation aluminium shell (1), heat conduction copper post (2), heronsbill radiator (3) are to contact by heat-conducting silicone grease.
Further, described heat radiation aluminium shell (1) back side is designed to column type, and cylindrical center is provided with counterbore.Described heat conduction copper post (2) is designed to the filled circles column type, heat conduction copper post (2) one ends are the light face, height equates with the counterbore height of heat radiation aluminium shell (1), and this light face diameter design also be designed to dispel the heat aperture of aluminium shell (1) back needle-like cylinder is equal, and light face diameter is done plus tolerance.Guarantee that heat radiation aluminium shell (1) becomes interference fit with heat conduction copper post (2), and on mating surface, be coated with and be added with heat-conducting silicone grease that heat conduction copper post (2) other end surface is provided with outer pitch thread.
Further, described heat conduction copper post (2) is the filled circles column type, cylinder one end is the light face, height is identical with the counterbore height of heat radiation aluminium shell (1), light face diameter is identical with the aperture of heat radiation aluminium shell (1) back side needle-like cylinder, light face diameter is done plus tolerance, and cylinder other end surface is provided with outer pitch thread.。
Further, described heronsbill radiator (3) is an extrudate, is with the heat radiation scale outside the heronsbill radiator (3), and middle one-tenth perforation is provided with screw thread in the hole, and tooth is apart from identical with the outer sound of baby talk distance of heat conduction copper post (2).
Beneficial effect of the present invention is:
1, can effectively the heat from LED lamp pearl be transmitted to radiator, and be dispersed in the air and go, prolong the service life of lamp.
2,, can prevent that mosquito, moth and dust etc. from falling into alluvial and reducing radiating effect owing to be needle-like heat radiation.
3,, can reduce the maintenance cost of street lamp and increase the heat radiation convection effects because street lamp is to be made up of a plurality of modules.
