Description

The stationary installation of heat radiator

Technical field

The utility model relates to the stationary installation of heat radiator, especially refer to that a kind of impact style that utilizes comes the pressure section upper surface of punching press in holding block, make it support the distortion of groove both sides, reach to be fixed in and reach the elastomeric horizontal base of clamping between adjacent two fins in it, collude in order to the buckling parts of pulling elastic body two side cantilevered distal end and to close on circuit board in the default holding part, save cost, difficult drop-off and effect easy to use to reach.

Background technology

Now, more and more higher for the arithmetic capability and the rate request of electronic chip, break through usual standard especially for bulk shape and structure.More because the wafer of a new generation has arithmetic capability more fast, make that also the temperature that is produced is higher when handling various operational order, and the main frame of general computer or notebook computer also develops towards light, thin, short, little direction, and utilize good cooling system, can make wafer operate as normal under the temperature of its permission, be considered as very important problem by industry, so, therefore relevant dealer just designs has and can heat radiator can be used for activity orientation on wafer for the heat radiator device of wafer use.

Consult Fig. 5, be the three-dimensional exploded view of commonly using radiating fin fixing device.Mainly extend a base portion A1 at two diagonal angles of heat radiator A, and establish a fastening hole A11 in base portion, pass the button hole C1 of fastening hole A11 and circuit board C by plastic cement fastener B, heat radiator A is fixed on the circuit board C, make the surface of contact A2 of heat radiator A bottom surface support the upper surface that is attached to wafer D, in order to the effect that reaches heat radiation, yet the above-mentioned locator meams of commonly using derives numerous disappearances also, now because of computer in handling process, having the situation of rocking and colliding unavoidably takes place, as with the above-mentioned locator meams of commonly using, for preventing that heat radiator A is because of rocking or colliding and cause the come off situation of skew of heat radiator A to take place, the tolerance of this plastic cement fastener B needs very accurate, just unlikelyly heat radiator A is produced rock and causes the location uncertain, and the elasticity of this kind plastic cement fastener B compresses also weak, so how to design fastener more of new generation, make in conjunction with after integral body have concurrently and stable do not rock and can effectively save cost, be the very crux that this journey dealer desires most ardently improvement, real still have can be to be improved the space person of existence.

So, the creator thinks hard the definite value mode of its heat radiator of research and wafer in view of the above-mentioned disappearance of commonly using article, and at the disappearance that is subjected to very easily to come off after external force collision or the vibrations, again through constantly test and design, and design the stationary installation of a with low cost and heat radiator that fixing is firm.

Summary of the invention

The purpose of this utility model is: provide a kind of and can make supporting groove both sides distortion and being positioned between the fin of heat radiator of holding block by impact style, and can fix elastomeric horizontal base simultaneously and its terminal buckling parts is colluded close in the holding part default on circuit board and locate, to reach the stationary installation of saving cost, difficult drop-off and being difficult for the heat radiator of skew.

Secondary objective of the present utility model is: provide the cantilever that bends on a kind of elastic body two side direction outwards to be the state of inclination, two cantilevers have an angle, when colluding the holding part that closes on circuit board in order to its terminal buckling parts, can make cantilever have an elasticity and pull and support power, make the upper surface that is fitted in wafer that the surface of contact of heat radiator can be more smooth, and the cushion effect when being subjected to external force collision or vibrations is provided simultaneously.

The utility model is achieved through the following technical solutions: a kind of stationary installation of heat radiator, comprise heat radiator, elastic body and holding block, this holding block is fixed on elastic body on the heat radiator, make the surface of contact of heat radiator can support the upper surface that is affixed on wafer, this elastic body forms the binding location with heat radiator and wafer below circuit board, it is characterized in that: the top of this heat radiator convexes with plural fin, and between the adjacent fin of appropriate location, be formed with dovetail type passage, and the bottom of heat radiator is provided with the surface of contact that can supply wafer to fit;

This elastic body is provided with a horizontal base in central authorities, and extends the cantilever by last outward-dipping bending in the horizontal base both sides, and this cantilevered distal end has extended a buckling parts;

This holding block has extended a pressure section in the top, the bottom central authorities of holding block cut open and are provided with one and support groove.Wherein:

Groove two sidewalls that support of described holding block form distortion and then are engaged between adjacent fin in the formed dovetail type passage, elastomeric horizontal base are positioned at support groove to become one.

Central authorities are provided with groove in the dovetail type passage of described heat radiator, but a horizontal base of these groove ammunition feed gonosome central authorities location.

The utility model is positioned between the fin of heat radiator owing to supporting the distortion of groove both sides, the buckling parts of elastomeric horizontal base colludes to close on circuit board and locatees, elastic body has an elasticity and pulls and supports power in addition, so can make more smooth being fitted on the wafer of surface of contact of heat radiator, even when external force collision or vibrations, because of combination firmly, the effect of cushion effect, and the phenomenon that can not come off, be offset, and simple in structure, cost is low.
