Description

Non-fan chip heat radiator
One technical field
The present invention relates to a kind of chip heat radiator, particularly a kind of non-fan chip heat radiator of the occasion that is applicable to the industry spot of dust, pollution or serious vibration and needs peace and quiet especially.
Two background technologies
Often pollute with particles such as serious dust, oil smoke at the industrial production scene.Therefore; the computer of fast turn-around work under this environment; not only to bear the influence of self heat; also to suffer the serious erosion of dust, oil smoke; at present; the normal fan that adopts is to each device of the computer especially heat dissipating method of process chip; also only solve heat dissipation problem, and because fan belongs to engineering goods, the life-span is limited; noise is also bigger; therefore can often cause the puzzlement of shutdown and fan noise, add insurmountable dust, oil smoke, not only make computer to dissipate heat not good; also can frequently crash, even cause the corrosion of circuit and components and parts.Patent of invention 200510026459.X, a kind of heat radiator without fan is disclosed, it mainly is to use semiconductor refrigeration chip to add the heat dissipation metal plate cooling, though avoided the noise of fan, but the heat that the refrigerating chip hot junction produces is quite big, and it is unfavorable to the heat radiation of other chips directly to be discharged in the cabinet, and whole device is bigger simultaneously, can only be a CPU heat radiation, and to require mainboard be passive mainboard.Patent of invention number 200510087127.2 disclosed a kind of heat radiator without fan, it mainly is the radiating effect that has further improved computer by the compressing structure that adopts heat carrier and finned radiator and thermal source assembly, pollution not explanation in open file for dust and oil smoke, but analyze according to this construction for heat radiating device, if this device also need be added a cover casing, control dust and oil smoke that then can be to a certain degree, but heat radiation can be affected again, if do not add casing, then can't solve dust and fume pollution problem, in addition, this device is complicated with the cabinet syndeton, also can cause whole electronic installation work under bad environment in the time of heat radiation with heat discharge to cabinet inside.
Three summary of the invention
The object of the present invention is to provide a kind ofly can not only stop entering of dust and oil smoke, and good heat dissipation effect, can accurately control the temperature that needs heat radiation chip, can also play reinforcement effect to chip, non-fan chip heat radiator simple in structure, reliable and stable.
The objective of the invention is to be achieved through the following technical solutions, non-fan chip heat radiator, it contains heat carrier and finned radiator, it is characterized in that it is to adopt cabinet as radiator, the outer surface setting of cooling cabinet has equally spaced metal fins, have the groove guide rail in cooling cabinet inside with the chip correspondence position, heat carrier is that the cross section is I-shaped heat conductive rubber, the hot junction of heat conductive rubber is inserted in the interior groove guide rail of cooling cabinet, and can move along the groove guide rail, between heat conductive rubber and the cabinet groove guide rail is interference fit, the cold junction face of heat conductive rubber has the groove suitable with die size, the bottom surface of groove is provided with refrigerating chip, and the cold junction of refrigerating chip closely contacts with chip under the pressure of cooling cabinet and heat conductive rubber.
Non-fan chip heat radiator of the present invention, be directly to add after the metal fins as radiator with the cabinet appearance, with with the chip of needs heat radiations one to one the heat conductive rubber piece as heat carrier, and the cold junction of heat conductive rubber piece closely contacts with the chip that will dispel the heat by a refrigerating chip, the heat that chip is given out is taken out of by the hot junction of refrigerating chip, directly promptly pass to cabinet by heat conductive rubber, by the metal fins on the cabinet heat is distributed to outside the case again.Heat imports cabinet inside in heat conduction and the heat radiation process, and the present invention has added heat-barrier material on cooling cabinet other inwall except that the groove guide rail; Except that cold and hot end face, also all added heat-barrier material at heat conductive rubber.In addition, cooperating between heat conductive rubber and the cabinet groove is interference fit, after chip position is determined, the hot junction of heat conductive rubber just can move to the chip top along the groove guide rail, frictional force by the interference fit generation, the hot junction that makes heat conductive rubber in the groove guide rail with the casing secure fixation, the total length of heat conductive rubber just is in the scope that the cold junction face that is positioned at its cold junction groove refrigerating chip and the upper surface of chip are closely contacted, like this, this device can also play the effect that compresses, fixes to chip when taking away heat.
The present invention compared with prior art its significant advantage is: the cabinet that directly adopts the band metal fins is as radiator, and be that heat conductive rubber is connected and fixed by groove guide rail in the cabinet and heat carrier, not needing to change cabinet just can adjust the heat radiation position on demand, realize simultaneously more than one chip being dispelled the heat, the contaminated environment of isolating dust and oil smoke fully, also have the effect that is fixed simultaneously concurrently to chip, the present invention is simple in structure, freedom from vibration is better, noiselessness disturbs, can be widely used in various electronic and electrical equipment and product, be specially adapted to dust, the electronic and electrical equipment and the product of the industry spot of pollution or serious vibration and the occasion that needs peace and quiet especially.
