Background technology
The cooling technology of current LED has four kinds: naturally cool, the cooling of air-cooled, heat pipe and compulsory circulative cooling.Naturally cooling is only limitted to small-power or the very low situation of unit are power; Air-cooled employing casting radiating fin (fin) mode is outwards conducted heat, and its consumptive material is many, and weight is large, and efficiency is low, and cost is high; Heat pipe-type cooling is due to cooling medium skewness on heating face, and cause inhomogeneous cooling even, efficiency is low, and in whole LED group, each monomer life-span differs, and luminous power differs; Forced cyclic type is forced distinguished and admirable or is forced liquid stream all to need power consumption, and mandatory component waits causing trouble rate high owing to using wearing and tearing simultaneously, and the life-span is short.So, all there are some major defects in the above type of cooling, and there are great correlation in the intensity of illumination of LED and life-span with heat radiation, the performance of thermal component determines the development space of LED even to a certain extent, special in high-power, high reliability request, non-maintaining application, is cooled to the barrier in order to LED application.
Device of the present utility model takes condensing cooling technology, with the cooling effectiveness that it is higher, high reliability, non-maintaining by the special application field expansion greater room for LED.
Utility model content
The purpose of this utility model: the utility model object is the cooling for LED, proposes a kind of cooling device of low-cost high-efficiency.
The technical solution of the utility model: a kind of LED cooling device, comprise heat-conducting plate 1, cooling chamber wall 2, radiating tube 3 and cooling medium 4, it is characterized in that, heat-conducting plate 1 and cooling chamber wall 2 form the cooling chamber of the held cooling medium 4 closed, heat-conducting plate 1 contacts with the substrate forming surface of LED5 or directly as LED-baseplate, cooling medium 4 directly contacts in cooling chamber with heat-conducting plate 1, cooling chamber wall 2 is provided with several radiating tubes 3, radiating tube 3 one end open one end seals, openend communicates with cooling chamber and is tightly connected, it is outside that sealed end is positioned at cooling chamber wall 2, increase and extraneous contact area.
The boiling point of described cooling medium 4 is-40 DEG C---100 DEG C.
Described radiating tube 3 can adopt various geometry to adjust its heat-sinking capability.
The non-ferrous metal that described heat-conducting plate 1 adopts heat conduction good.
Described cooling chamber wall 2 adopt metal or nonmetal by mold pressing, casting make, adopt with the connection of heat-conducting plate 1 and weld or other modes that are tightly connected.
Described radiating tube 3 adopt with the connection of cooling chamber weld, mold pressing, casting, expanded joint means realize.Also comprise some stiffeners 6, stiffener 6 is arranged on cooling chamber inside.
Advantage of the present utility model: the utility model has heat absorption evenly, heat transfer efficiency is high, do not need the outside supply energy, anti-pollution, non-maintaining, the advantages such as the life-span is long, can well solve the four problems that LED cools field: 1. have the temperature conditions that qualified when ensureing a large amount of light-emitting component of cluster arrangement on limited areal; 2. when arranging a large amount of LED illuminating part on certain area, the operating ambient temperature of each is basically identical, thus reaches that brightness is consistent, the life-span is consistent; 3. ensure the occasion reliability service of LED at unmanned or not easily repair and maintenance; 4. under realizing the prerequisite of above-mentioned target, cost does not rise or declines to some extent.
Accompanying drawing illustrates:
Fig. 1 is the utility model structure and connection diagram;
Fig. 2 is another embodiment schematic diagram of the utility model;
Wherein, 1 is heat-conducting plate, and 2 is cooling chamber wall, and 3 is radiating tube, and 4 is cooling medium, and 5 is LED, and 6 is stiffener.
Detailed description of the invention: the utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, the utility model structure comprises heat-conducting plate 1, cooling chamber wall 2, radiating tube 3 and cooling medium 4, it is characterized in that, heat-conducting plate 1 and cooling chamber wall 2 form the cooling chamber of the held cooling medium 4 closed, heat-conducting plate 1 contacts with the substrate forming surface of LED5 or directly as LED-baseplate, cooling medium 4 directly contacts in cooling chamber with heat-conducting plate 1, cooling chamber wall 2 is provided with several radiating tubes 3, radiating tube 3 one end open one end seals, openend communicates with cooling chamber and is tightly connected, it is outside that sealed end is positioned at cooling chamber wall 2, increase and extraneous contact area.Described cooling medium 4 boiling point is-40 DEG C---100 DEG C.Described radiating tube 3 can adopt various geometry, as structures such as cylindricality, profile of tooth, taper, rhombuses, to adjust its heat-sinking capability.The non-ferrous metal that described heat-conducting plate 1 adopts heat conduction good or the good material of other heat conduction.Described cooling chamber wall 2 is adopted metal or nonmetally to be made by mold pressing, casting etc., adopts weld or other modes that are tightly connected with the connection of heat-conducting plate 1.Described radiating tube 3 adopt with the connection of cooling chamber weld, mold pressing, casting, the means such as expanded joint realize, best mode, also comprises some stiffeners 6, and stiffener 6 is arranged on cooling chamber inside, and stiffener plays the effect from internal reinforcement cooling device.
