Abstract

The utility model provides a welding processing mould for radiator fin and base plate, which is mainly composed of a first die holder and a second die holder, wherein, the first die holder for supporting the base plate is arranged under the base plate of the radiator; the second die holder is arranged above the U-shaped radiator fin. The second die holder is provided with a pressing part and a junction part. The pressing part is at least extended with a pressure bar relative to the bending position of the U-shaped radiator fin, while the junction part which provides energy and generates high heat is arranged at the bottom of the pressure bar. When the pressing part gives pressure to the pressure bar, the U-shaped radiator is pressed at the top of the base plate. By the high heat generated by the junction part, the U-shaped radiator can be welded with the base plate quickly.

Description

The welding processing mould of radiator fins and base plate

The utility model has provided the welding processing mould of a kind of radiator fins and base plate, it is fixing to be intended to make the U type fin of radiator and base plate to be utilized welding processing to finish, with the radiating efficiency of increase radiator, and has the effect that the welding processing of making is finished fast.

Because aluminium has characteristics such as heat transfer efficiency height and lower cost for material, therefore existing radiator all adopts aluminium to make.Its structure comprises base plate 1 and is located at the multi-disc radiating fin 2 of base plate 1 end face as shown in Figure 1; Wherein, base plate 1 bottom surface is superimposed in the end face for the treatment of heat-dissipating thing 3, treat the high heat that heat-dissipating thing 3 produces in order to absorption, 2 of radiating fins are located at base plate 1 top, the high heat that base plate 1 is absorbed is transmitted to each sheet radiating fin 2 rapidly, and, the high heat for the treatment of heat-dissipating thing 3 generations is lowered the temperature by this by radiating fin 2 and cold air convection heat exchange.

Because aluminium has high ductibility and low-melting characteristic, therefore aforesaid radiator all utilizes the technology that extrudes one-body molded during fabrication.The radiator of this extrusion forming of thought, radiating fin can not be too thin when extruding for its shortcoming, distance between fin and fin can not be too near, otherwise fin has interrupted situation appearance when extruding, just cause the restriction of radiating fin quantity thus, therefore area of dissipation dwindles, and thicker fin material cost is higher, weight is also heavier, is unfavorable for the fast development of matching computer.

In view of the above-mentioned shortcoming that extrudes the radiator of technology moulding, develop again at present and a kind of radiator shown in Fig. 2,3, the structure of this radiator mainly is radiating fin 20 to be designed to the U type bend continuously, and the bottom surface of bending is a flat shape, base plate 10 then is a tabular, the bottom that radiating fin 20 is straight is superimposed adhere to base plate 10 end faces after, can finish assembling.

This base plate 10 separates the radiator of making the back recombinant with radiating fin 20, mainly be to utilize radiating fin to be the U type structure of bending continuously, make radiating fin thickness be able to thin, heat conduction and radiating effect is able to preferable advantage, overcome the not good shortcoming of radiating effect of aforementioned one-body molded radiator.But because this combined radiator, there is no suitable equipment or instrument and produce during with base plate 10 at processing assembling radiating fin 20, it is bonding to be coated with colloid in base plate and radiating fin junction in advance, so causes the inconvenience in the automated production; Especially scribble colloid between base plate and the radiating fin, harmful effect is obviously arranged for the heat-conducting effect between the two.

This creator in view of this, it is the practical experience that obtains the professional knowledge of U.S. state university manufacturing engineering doctorate and research and develop like product for many years according to it, structure at this kind combined radiator comes research and design in addition, after through continuous experiment and test, can create out the welding processing mould of a kind of radiator fins and base plate eventually, by this can solve the variety of issue of radiator on combination is made.
