Description
Technical field
The utility model relates to the radiator of tool heat pipe, refers to that especially a kind of moulding is quick, non-environmental-pollution, has the heat pipe of preferable heat conduction efficiency and the riveted structure of radiating fin.
Background technology
The heat radiation type of general central processing unit or electronic component generally is divided into two kinds: one, the radiator that will be made up of a plurality of fin, on-line equipment are equipped with fan again and dry and make its heat radiation on central processing unit; Its two, the heat pipe of interior dress working fluid is connected in central processing unit or electronic component, the heat pipe other end is received the radiator of being made up of a plurality of fin; Second kind of radiating mode, mainly idle because of being subject to installing, radiator and fan can't directly be set, or because of central processing unit, electronic component have higher heat radiation requirement, so the radiator that needs the employing heat pipe to receive, to reach rapidly effectively heat radiation; Commonly use the combination of heat pipe and fin, mainly on heat pipe and faying face that fin is connected, be coated with one deck scolder, insert the vacuum furnace heating, scolder is melted in heating process, and infiltrate the faying face of heat pipe and fin by capillarity, through cooling off the two is welded as a whole; Though this kind processing procedure can reach certain effect, but must cooperate special production equipment (as vacuum furnace), simultaneously, processing procedure is long and control model is quite careful, complicated, make production efficiency low, yield poorly, therefore, time-consuming, the manufacturing cost height, in addition, adopt in the processing procedure that heats the solder fusing joint filling and can produce harmful human body, the waste gas of contaminated environment, waste water, and the high concentration that contains in the solder component is plumbous and other heavy metal, also can encroach on human body, the harm biological environment, therefore, adopting scolder with the mode that heat pipe combines with fin, is a kind of high pollution, the industrial process of high harm.
Referring to shown in Figure 1, in view of commonly using the shortcoming that the heat pipe radiator exists, having the dealer to use friction tight mode instead combines heat pipe with fin, wherein, each fin 10 punch forming has and heat pipe 11 corresponding axis holes 12, heat pipe 11 is fixed on the smelting tool (not shown), adopt each fin 10 of automation facility moulding, simultaneously moulding fin 10 is set on the heat pipe 11, again with mould punching press one by one in regular turn (promptly a punching press one fin) each time, make each fin 10 be the suit riveting status with heat pipe 11: however the shortcoming of this kind operation procedure is that each moulding fin 10 must be set in heat pipe 11 punching press one by one in regular turn.Therefore, make a finished product, must repeatedly repeat to wear and to finish with the punching press program, owing to the error of facility punching press vibrations or moulding fin 10, all can influence the location and the packing degree of heat pipe 11 and fin 10 in addition, produce clearance C 1 (as shown in Figure 2) at heat pipe 11 and 12 of each fin 10 axis holes, except that the suitable height of finished product disqualification rate, and improve its thermal resistance, have a strong impact on heat pipe 11 heat is conducted to the heat conduction efficiency of fin 10, cause radiating effect not good; Can with heat pipe 11 rivetings knots, remove whole punching press processing procedure and expend the long duration, reduce outside the production efficiency, the punching press fin constantly many times of mould can cause the consume aggravation simultaneously, influences the accuracy of punching press, shortens its useful life; Because each fin 10 is by the punch forming of automation facility; to be set on the heat pipe 11 immediately after the moulding; again by mould punching press one by one; riveting is tied on heat pipe 11; but; in the punching press program of fin 10; must make fin 10 be full of lubricant grease,, and be convenient to punch forming and blanking with protection punching press facility and mould; therefore; each moulding fin 10 contains suitable oil stain, and when heat pipe 11 was set in each moulding fin 10 punching press, the oil stain on it can infiltrate faying face because of capillarity; thereby cause the oxidation of heat pipe 11; the result of heat pipe 11 oxidations directly makes the thermal resistance of its faying face increase, and reduces the heat conduction efficiency of heat pipe 11; so the practicality and the durability of this processing procedure are not good, be necessary to be improved in fact.
