Description

Vertical combined type heat transfer radiating device manufacturing method

Technical field

The present invention is about a kind of vertical combined type heat transfer radiating device manufacturing method, especially a kind of assembly that sees through of finger is tightly tied technology with combination making tool open zone, exposed parts heat pipe direct heat is engaged in electronic building brick, to form the heat abstractor preparation method of thermal energy transfer configuration, can improve the assembly tightly property tied, heat transference efficiency and reduce cost.

Background technology

Known, the heat abstractor of the present electronic building brick that is applied to, especially require the heat abstractor 1 of better cooling efficiency, all be to see through heat pipe 11 to form with radiating fin 12, see through heat-conducting base 13 and electronic building brick 2 formation area formula thermal bondings that heat pipe 11 extends the combination of end institute again, heat energy with quick transmission electronic building brick 2 generations, be passed to several dissipation fins 12 via heat pipe 11 and do large-area thermal transpiration, in other words, heat pipe 11 and heat-conducting base 13 combine design and adaptation etc., all will directly react and the thermal source transmission efficiency of 2 of electronic building bricks, its making and assembly cost are higher certainly.

Again, shown in Figure 1A, " the punching press locking structure that includes the heat abstractor of heat pipe is made " novel patent case for Taiwan patent gazette M268112 number, the emphasis of this patent case institute demand is that the end face at base 14 has at least one chase 15, differ from the axial moulding multiple tracks groove 16 of chase 15, heat pipe 17 is preset in the chase 15, and the fin 18 corresponding grooves 16 that insert of radiator, pressing heat pipe 17 simultaneously is positioned on the base 14, base 14 surfaces of mat mould punching press fin 18 both sides, make its pressurized produce and extend out deformation, make fin 18 must with base 14 riveteds, and heat pipe 17 tight knots are positioned 14 of fin 18 and bases.

But above-mentioned patent case still need see through base and electronic building brick thermal, in other words, still has tight knot adaptation and heat transference efficiency problem between heat pipe and base.

Summary of the invention

Main purpose of the present invention, be to solve above-mentioned tradition disappearance, the method for tightening redesign of heat abstractor of the present invention and inter-module thereof, the simple tool framework of arranging in pairs or groups, the technology of exerting pressure and assembly are tightly tied, exempt from the heat-conducting base combination with formation, and the heat pipe that is directly exposed by heat abstractor one open zone of making combines transferring heat energy with the electronic building brick direct heat and disperses, assembly method for tightening and manufactured goods thereof to heat abstractor, improve the tightly property tied of assembly, heat transference efficiency and reducing cost is to provide the user cheaper but high heat transfer efficient and the urgent practical heat abstractor that combines.

For reaching above-mentioned purpose, vertical combined type heat transfer radiating device manufacturing method of the present invention, this method step comprises: a fin integrating step, first radiating fin of the upper and lower combined hole of most tools is provided, and second radiating fin of combined hole and underlying groove on most tools, utilize set fastener button collection to form spacing and arrange and have a fins group in an indent open zone; One heat pipe integrating step is placed through the upper and lower combined hole of above-mentioned fins group and underlying groove with at least one heat pipe and part exposes to the open zone; Then, a urgent integrating step utilizes the most stamping parts of a die set and its to cooperate stamping technologies, each radiating fin and heat pipe corresponding preset is tightly tied the position impose the punching press brute force, integrally combines to form default distortion packing of tightly tying position and heat pipe; Finish the tool open zone is engaged electronic building brick heat transmission heat radiation with direct heat by heat pipe heat abstractor manufactured goods.

The present invention can directly use the heat pipe direct heat that exposes in this open zone and be engaged in electronic building brick and transfer heat energy to fins group with high efficiency and disperse, and to improve and tight knot property of the heat of heat-conducting base and heat transference efficiency problem, also can reduce and assemble and the assembly cost.
