Description

The conductive structure of embedded system low thermal resistance

Technical field

The utility model provides a kind of conductive structure of embedded system low thermal resistance, especially refer to utilize plural elasticity spacer elasticity stay bolt on heat-conducting block, make heat-conducting block elasticity support the lip-deep pressure stability equilibrium of pyrotoxin that is affixed on circuit board and fit tightly more with its thermal resistance of effective minimizing, improve the integral heat sink effect.

Background technology

Press, electronics technology is grown up with the speed of making rapid progress now, make the computer development trend also, speed fast direction strong towards calculation function stride forward, and along with the application of server, embedded system or other system host of computer, industrial computer trends towards high speed development, the temperature that produces during runnings such as its central processing unit, image processor also improves relatively, so will how to utilize radiator structure to guarantee operate as normal under the temperature that allows, be considered as the problem of the solution of desiring most ardently by industry.

Moreover, the present general practice of industry, be radiator to be supported form the radiator structure of optimizing on the pyrotoxin surface that is affixed on circuit board, and on using the pyrotoxin of differing heights the time, usually need to use thicker conducting strip to contain multiple pyrotoxin height dimension, or the radiator that must design the different structure size comes indivedual corresponding different pyrotoxin height, if consider the sharing of radiating seat, namely need use thicker conducting strip, certainly will will cause the raising of thermal resistance, and consider low thermal resistance, then need use the radiator of multiple different size.

Yet, radiator is considered the too high problem of thermal resistance, general big city uses certain thickness heat-conducting medium, and this heat-conducting medium can have influence on the increase and decrease of thermal resistance value because of the increase and decrease of thickness, in order to there is the dealer to develop the radiating module that pyrotoxin and radiator are more pressed close to, thickness with effective minimizing heat-conducting medium use, thereby thermal resistance value is reduced, as shown in Figure 9, the pedestal A1 of known radiating module A institute tool goes up to being concaved with can support the caulking groove A11 that pastes the location for plural heat pipe A2, and all be provided with hollow hole A12 in caulking groove A11 one side place, and the end A21 at heat pipe A2 one side place is for being welded in caulking groove A11, the heat pipe A2 end A21 at side place in addition then is inserted into hollow hole A12 place, and on A21 surface, end, be welded with metal derby A3, and be positioned at A21 two side corners in end on the metal derby A3 and be provided with the plurality of through holes A31 that can supply screw A32 to wear, can be earlier will be placed in respectively after the spring A33 compression between metal derby A3 and the pedestal A1 in the formed gap, and after passing among the spring A33 by screw A32, lock the lockhole A13 internal lock access node that is positioned at hollow hole A12 two side place correspondences in pedestal A1 again and synthesize one.

Only the metal derby A3 of this known radiating module A utilizes plural spring A33 to cushion, though its metal derby A3 can support the pyrotoxin that is contacted with circuit board and highly move up and down, and make heat pipe A2 reach the elastic force effect by the strong point by the hollow hole A12 of pedestal A1, metal derby A3 is contacted with pyrotoxin more closely to reduce its thermal resistance, but because the perforation A31 of metal derby A3 cooperates spring A33 assembling will take the contact area of heat pipe A2 part, thereby influence heat pipe A2 with the thermal energy conduction of metal derby pyrotoxin that A3 the absorbs radiating efficiency to the pedestal A1, though and this spring A33 elasticity supports to arrive in four corners of metal derby A3 and can reach the average effect of strength, but if wherein one side is bigger with the pressure that heat pipe A2 welding back forms for metal derby A3, to cause making metal derby A3 to be easy to generate tilting and build-up of pressure is inconsistent, make the heat conduction only be confined to specific one side simultaneously, can make also that metal derby A3 pressure is excessive to cause the structural damage of specific one side or destruction, influence integrally-built stability; Plural spring A33 is when assembling in addition, system will can be placed in after the spring A33 compression between metal derby A3 and perforation A31 and the pedestal A1 earlier smoothly, it is very inconvenient not only to cause in the spring A33 operation, and the degree of difficulty that screw A32 is passed when locking among the spring A33 in contraposition increases, and be unfavorable for quick assembling, then remain to be engaged in this journey dealer and redesign effectively and solved.
