Abstract

The utility model relates to a combination structure of heat radiating board, wherein, the bottom of a heat radiating board is arranged with a containing groove and a heat conductive block with regular or irregular concave-convex surfaces of four sides and top. The heat-conductive block is provided with a plurality of taper through holes. When in installment, first heats and softens the heat radiating board, using forging press method to press the heat-conductive block into the containing groove, and the concave-convex surfaces on the heat-conductive block improves the contact area with the containing groove, to press part walls of the containing groove into the taper through holes, while air can be discharged from the taper through holes to obtain ventilate function, and the pressed walls can draw downwards and contract after being cooled to combine the heat-conductive block and the heat radiating board tightly, thereby improving the heat radiating efficiency of the whole heat radiating board.

Description

The heating panel combined structure

Technical field

The utility model relates to a kind of heating panel combined structure, particularly relate to a kind of one side the high heat-conducting block of heat transfer efficiency is installed at heating panel, and heat-conducting block can be combined with heating panel more closely, with the heating panel combined structure of the radiating efficiency that improves the entire heat dissipation plate.

Background technology

Tradition is used the heating panel 6 on CPU, as shown in Figure 1 and Figure 2, this heating panel 6 is to be an aluminium extruded type, heating panel 6 is provided with integrated multi-disc radiating fin 61, above these radiating fins 61, radiator fan 62 is installed, and, for the radiating efficiency that makes entire heat dissipation plate 6 can be higher, one heat-conducting block 63 can be installed in the bottom of heating panel 6, this heat-conducting block 63 is the good copper material of heat-conducting effect, its mounting means is to be provided with a containing groove 64 in the bottom of heating panel 6, this heat-conducting block 63 is fixedly installed in the containing groove 64 again; So, this heating panel 6 can be installed in CPU 71 tops of printed circuit board (PCB) 7, and its heat-conducting block 63 is just to fit on the CPU 71, so the heat energy that is produced when by heat-conducting block 63 CPU 71 being turned round brings to heating panel 6, by radiator fan 62 heat energy is inhaled or blown to the external world again, and reach radiating effect.

And traditional heat-conducting block 63 is on being installed on heating panel 6 time, it mostly is to utilize the mode of gummed to make heat-conducting block 63 in conjunction with being fixed in the containing groove 64 of heating panel 6, because be to use the gummed mode, even being fixed in the containing groove 64, heat-conducting block 63 still can produce a little gap between it, make the not good situation of bonding tightness takes place between heat-conducting block 63 and the heating panel 6, so, can have influence on the radiating efficiency of entire heat dissipation plate 6 on the contrary, and lose the purpose that it increases dress heat-conducting block 63.

Summary of the invention

Main purpose of the present utility model is to provide a kind of heating panel combined structure, comprise a heating panel and a heat-conducting block, its heat-conducting block encloses and the end face place is provided with respectively to arrange and is rule or irregular male and fomale(M﹠F) all round at it, to increase the contact area between heat-conducting block and containing groove, have several taper perforation on the heat-conducting block, thereby the effect by the taper perforation can combine this heat-conducting block more closely with heating panel, so that improve the radiating efficiency of entire heat dissipation plate.

The utility model can be realized by following measures:

This heating panel bottom of the present utility model is formed with a containing groove, one heat-conducting block is installed in containing groove, this heat-conducting block encloses and the end face place is provided with respectively to arrange and is rule or irregular male and fomale(M﹠F) all round at it, its heat-conducting block is to use the high copper material of heat transfer efficiency, and has several taper perforation on heat-conducting block; During assembling, make the heating panel thermoplastic earlier, in the forging and pressing mode heat-conducting block is squeezed in the containing groove again, because, be male and fomale(M﹠F) on this heat-conducting block and increase and containing groove between contact area, and then the part wall body of containing groove is extruded in several tapers perforation, after cooling, it is extruded into the outer wall body of taper perforation and has the effect of leaving behind and tightening, and in contract to the taper perforation, and then heat-conducting block and heating panel are combined closely.

The perforation of described taper be this heat-conducting block to should heating panel the end at the back side be a loudspeaker reducing.

The heating-up temperature of described heating panel is about about 400 degree.

The utlity model has following advantage:

Heating panel combined structure provided by the utility model, the male and fomale(M﹠F) of its heat-conducting block increased and containing groove between contact area.Have several taper perforation on the heat-conducting block, in the time of in heat-conducting block is squeezed into containing groove, air can be discharged from the taper perforation, and heat-conducting block more can be fixed on the heating panel closely; It is extruded into the outer wall body of taper perforation and has the effect of leaving behind and tightening when cooling, and in contract to taper perforation, and then heat-conducting block and heating panel are combined closely, thereby the heat energy that this heat-conducting block is produced in the time of more completely CPU being turned round brings on the heating panel, has improved the radiating efficiency of entire heat dissipation plate.

The present invention also will be described in further detail specific embodiment in conjunction with the accompanying drawings.
