Abstract
A processing technique for radiators changes metal welding or extrusion processing which are used consecutively into a bonded processing technique. Adopting a bonding technique, a base plate and cooling parts are bonded of the radiator by strong glue with good heat conductivity. The processing technique has exact making method that: processing a groove or a hole which is matched with cooling parts on the base plate of the radiator, leaving a certain clearance, arranging the cooling parts in the groove or the hole processed on the base plate, the bonding the cooling parts and the base plate by strong glue which is in market currency. The method can be used for processing various radiators with high power thyristor elements. The invention has the advantages of reliable working, airtightness and strength, beautiful appearance. Comparing with the soft extrusion processing technique, the invention reduces thermal resistance, improves working reliability; has lower cost than that of metal welding processing technique, increases production efficiency.

Technical field
The present invention relates to a kind of technological method for processing of mechanical part structure, refer in particular to the technological method for processing of a kind of high-power components radiator (as the radiator of high-power thyristor), mainly be useful for manufacture and the product of high-power electronic component with radiator.Also can be useful for manufacture and the product of various electronic components of high power with radiator.
Background technology
Many high-power components are in running, and often because the consumption of power can produce a large amount of heat, this heat can make the temperature of device rise, if, then can influence the performance of product because the device temperature rise is too high, even scaling loss device or cause the inefficacy of device.Too high in order to prevent that power component from heating up, often need device to be dispelled the heat with radiator.The radiator of high-power components mainly contains general radiator, heat-pipe radiator and water-filled radiator now.Heat-pipe radiator is made up of substrate, heat pipe and fin; Water-filled radiator is made up of substrate and cover plate.General radiator is made up of substrate, fin; Heat-pipe radiator is made up of substrate, heat pipe and fin; Water-filled radiator is made up of substrate and cover plate.Along with science and technology development, the power component technology content is more and more higher, uses more and more widely, and the radiator that uses that matches has with it also proposed requirements at the higher level technically.High-power components particularly, the manufacturing of radiator in the past except that Section Bar Heat Sinks all fetch processing by extruding and metal welding, and the radiating effect of extruding is not very desirable, the contact heat resistance height, and functional reliability is poor; And the cost of welding is higher, and in order to reduce production costs and guarantee the radiating effect and the functional reliability of radiator, we must seek a kind of new manufacture method and solve above problem.
Summary of the invention
The present invention aims to provide a kind of better radiator processing and fabricating method, is guaranteeing to have the reliability height under the product quality premise according to the produced radiator of this method, and cost is low, working (machining) efficiency height, good heat dissipation effect, the characteristics of the beautiful grade of outward appearance.
Purpose of the present invention is achieved by following technical proposals: a kind of radiator processing and fabricating method is characterized in that: the substrate of radiator and thermal component are with the good super glue of thermal conductivity, adopt technique for sticking to be bonded together.Concrete manufacture method is: process the groove or the hole that match with heat sink on the substrate of radiator, and leave certain clearance, heat sink is inserted in the groove or hole that processes on the substrate, again with super glue with heat sink and substrate bonding together.Described super glue is the general super glue in market.In order to strengthen the heat-conducting effect of super glue, can also increase a certain proportion of heat-conducting metal powder in super glue, to reduce contact heat resistance.The heat-conducting metal powder can be copper powder, aluminium powder, zinc powder or stainless steel powder.
The invention has the advantages that: new technology improves production efficiency of products and reduces cost when guaranteeing its radiating effect and functional reliability.Be characterized in making substrate and fin to be bonded together securely, can bear bigger outer active force, with respect to the processing technology of extruding, the reliability of work is higher; Processing technology with respect to welding has reduced cost, has improved benefit.
