Abstract
A composite material heat sink is composed of a substrate, and a coil pipe and a special-shaped transition connecting pipe die-cast in the substrate, wherein the substrate material is aluminum alloy, the coil pipe is composed of multiple U shaped pipes, and ports of all U shaped pipes are communicated with the special-shaped transition connecting pipe through welding, forming a communicated liquid coolant passing channel. The substrate material tightly wraps the coil pipe, heat between the coil pipe and the substrate material, and between the coil pipe and the liquid coolant is radiated through conduction and convection, the heat radiation efficiency is greatly raised; and the heat sink has the advantages of easiness in manufacturing, low manufacturing cost, stable working performance, safety and reliability, and is suitable a large-scale electronic equipment system.
Description
Technical field
The utility model relates to a kind of composite material cooling plate structure, and especially a kind of large scale electronic equipment and control system thereof are used the aluminium alloy cooling plate structure.
Background technology
Heating panel is heat conducting important a, critical component between large scale electronic equipment and control system electronic devices and components thereof.It is widely used in various large scale electronic equipments and control system thereof, with electronic devices and components operate as normal in the assurance system, ensures that whole system is safe and reliable.
The heating panel that uses in large scale electronic equipment and the control system thereof; Mostly be in basis material, to be provided with the perforation cooling holes, overall volume is bigger, and is as shown in Figure 1; The heating panel that present domestic large scale electronic equipment and control system thereof are used all adopts the monometallic material manufacture; Or through machining assembling welding or gluing forming, heat conduction efficiency is poor, influences the function of use and the working life of electronic devices and components.And, deep hole processing on the elemental metals material, or all very high through a large amount of machining assembling welding or gluing cost, and the process-cycle is very long, is unfavorable for producing in batches.Therefore at present the type heating panel of domestic production all can not satisfy performance requirement, mainly is that radiating efficiency is poor, causes the technical performance of large scale electronic equipment system low, poor reliability, life-span be short, has economy defectives such as cost is high, output is little simultaneously.
The utility model content
The purpose of the utility model is in order to overcome the deficiency of above-mentioned technology, to provide a kind of large scale electronic equipment simple in structure, that be convenient to die-casting process to use cooling plate structure, satisfies the instructions for use of domestic large scale electronic equipment system.
The said composite material heating panel of the utility model; Form by matrix and the coil pipe and the special-shaped transition tube connector of die casting in matrix; Said basis material is an aluminium alloy; Coil pipe is rearranged by a plurality of U-shaped pipes, and all U-shaped pipe ports all are communicated with through welding with special-shaped transition tube connector, the cooling fluid that the forms connection runner that stimulates the menstrual flow.
Said matrix is the XL392 pack alloy, and the material of coil pipe and special-shaped transition tube connector adopts stainless steel.Adopt certain corrosion resistance that the utlity model has of technique scheme, can in different air ambients, use.Since through the integral die-cast moulding, inlay closely contact between coil pipe and the special-shaped transition tube connector in the alloy matrix aluminum, higher more than 60% than domestic existing heat conduction efficiency through machining assembling welding or the gluing the type heating panel that forms.Therefore, the utility model compared with prior art, have make easily, manufacturing cost is lower, stable work in work, advantage such as safe and reliable.

Among the figure: 1-matrix, 2-abnormity transition tube connector, 3-coil pipe.
Embodiment
As shown in the figure; The said composite material heating panel of the utility model; Be made up of matrix 1 and die casting coil pipe 3 and special-shaped transition tube connector 2 in matrix 1, said matrix 1 material is an aluminium alloy, and coil pipe 3 is rearranged by a plurality of U-shaped pipes; All U-shaped pipe ports all are communicated with through welding with special-shaped transition tube connector 2, the cooling fluid that the forms connection runner that stimulates the menstrual flow.
Cut into the bulk material that needs size with stainless steel thick plate earlier during making; Pass through line cutting, electric spark, be machined into special-shaped transition tube connector 2; Using internal diameter again is 5 ~ 8mm; External diameter is that the U-shaped pipe that 6 ~ 10mm stainless steel tube is bent into one group of three different size is arranged in order on same plane from small to large, and coil pipe 3 ports and special-shaped transition tube connector 2 that all U-shaped pipes are formed is integrally welded.Be connected with the external refrigeration pipe for ease of special-shaped transition tube connector 2; Its two ends are processed as screwed pipe; To weld good coil pipe 3 and special-shaped transition tube connector 2 then, to be placed on the mould internal fixation good; Molten aluminium alloy is injected mold cavity through high speed and high pressure, solidify the back and form the heating panel part that is the main body with alloy matrix aluminum (1).This heating panel overall dimension is long 500 ~ 2000mm, wide 90 ~ 200mm, and thick is 10 ~ 18mm.Through shaping, heat treatment, machining, detection, finally make the said heating panel of the utility model again.
