Description
The present invention relates to a kind of Radiator and its preparation method, be meant that especially a kind of radiating effect is good and make easy Radiator and its preparation method.
Along with developing rapidly of computerized information industry, the various electrical equipments of the inner installing of computer are also increasing, for example: wafer, power supply unit, magnetic disc driver, CD drive etc.Because these electrical equipments in running, all can produce suitable heat,, will have influence on the normal operation of electrical equipment if untimely with these heats discharges.So, how to solve the heat dissipation problem of these electrical equipments, to guarantee the stability and the quality of computer signal transmission, become the problem that needs to be resolved hurrily.
The method of existing solution related electric element radiating problem generally all is installing one radiator on electrical equipment, discharging heat timely and effectively, and guarantees electrical equipment normally operation under suitable temperature.But the quality of radiator heat-dissipation effect is all closely related with its material, structure, manufacture method and manufacturing technology etc.
With regard to general common radiator, the ratio (h/d) of its fin height h and fin pitch d is big more, and then radiating effect is good more.The manufacture method of this class radiator is to extrude earlier (extruding) on a certain direction, along perpendicular to profile groove (sawing) on the other direction of this direction, protrudes out the fin of arrangement in order to the formation array way again.The radiator that adopts this class mode to make except the program of back segment machining is loaded down with trivial details, further because mould, extrude the restriction on technology and the material, can't obtain the ratio of gratifying fin height h and fin pitch d, so radiating effect is limited.
For solving the problem that above-mentioned radiator exists, produced separate type radiator as shown in Figure 1, this radiator 10 is made up of an aluminium matrix 20 and the some fins 30 that are plugged on the matrix 20.This matrix 20 is flat and has specific thickness, and it top also offers the accepting hole 201 that several are arranged with array way.This fin 30 slightly is palisade, and its below one is extended several heat-conducting parts 301, in order to being plugged in the accepting hole 201 on the matrix 20, and fin 30 is installed on the matrix 20.After this fin 30 is plugged on the matrix 20, utilize suitable tool to impact the upper surface 303 of fin 30 connecting portions 302, the lower surface of connecting portion 302 and the end face of matrix 20 are fitted tightly, and the space of reducing fin 30 and 20 of matrixes produce the integral heat sink effect of enhancement radiator 10.
Because the matrix 20 of this radiator 10 and fin 30 all are to be made by punching press,, and on the ratio of fin height and fin pitch, also be better than existing radiator so relevant more existing the extruding of manufacturing procedure adds that profile groove is easy.Yet, consider radiating effect, this matrix 20 must have suitable thickness, therefore at punching press matrix 20 when forming relevant accepting hole 201, the size of this accepting hole 201, and the distance of 201 of accepting holes etc., must suitably strengthen, to avoid matrix 20 torsional deformations.Restriction on these radiating effects and the punching press processing procedure, obviously to the thickness of the fin 30 that cooperates with accepting hole 201, and the ratio of fin height and fin pitch etc. designs unfavorablely, further influences the integral heat sink effect of radiator 10.In addition, though 20 of the fin 30 of this radiator 10 and matrixes further utilize suitable tool to impact, produce in order to the space of reducing between the two, actual radiating effect is still desirable not to the utmost.
In addition, in Fig. 2, the below one of the fin 130 of radiator 110 is extended several heat-conducting parts 1301, and this heat-conducting part 1301 and palisade radiating part 1303 are crisscross arranged.Utilize suitable tool to impact the upper surface 1304 of fin 130 connecting portions 1302, just can make the lower surface of connecting portion 1302 and the end face of matrix 120, and 1201 of the accepting holes of heat-conducting part 1301 and matrix 120 all fit tightly, and the space of reducing fin 130 and 120 of matrixes produces the integral heat sink effect of enhancement radiator 110.Yet this class radiator still exists same defect, and actual radiating effect still is not inconsistent user demand.
It is good and make easy Radiator and its preparation method to the purpose of this invention is to provide a kind of radiating effect.
The present invention is about a kind of Radiator and its preparation method, and wherein this radiator comprises one first matrix, one second matrix and some fins.Offer first accepting hole that several extend through the bottom surface and arrange with array way from end face on first matrix, second matrix is superimposed on the bottom surface of first matrix, and it is in the position of corresponding first matrix, first accepting hole, correspondingly offers several extend through the bottom surface from end face second accepting hole.This first matrix is identical with the dimensions of second matrix, so can adopt identical materials and mould punching press to make.This fin slightly is palisade, its top is several radiating parts, the heat-conducting part of several corresponding settings with radiating part is extended in below then one, be used for being plugged on first accepting hole of first matrix and second accepting hole of second matrix, linked with a junction between this radiating part and heat-conducting part.The length of this heat-conducting part is the integral thickness after superimposed greater than first matrix and second matrix, so its tip end projects goes out outside the bottom surface of second matrix.
Owing to adopted technique scheme, the present invention can optimize the radiating effect of radiator greatly, and its manufacture method is also simplified.
