Abstract
The utility model discloses a high power electronic device radiator which is composed of radiating flanges, a fixed pipe and a heat radiation bottom board. Grooves are arranged on the heat radiation bottom board, the ends of each two radiating flanges are installed into one groove of the heat radiation bottom board in pair, the fixed pipe is installed between the ends of two radiating flanges which are installed in the groove of the heat radiation bottom board, the fixed pipe is pressed in through the apparent force and is squeezed due to the size limitation of two sides of the groove, bounce impact force deformation is generated, which enables the end side surfaces of the two radiating flanges to be closely pressed on the groove wall of the heat radiation bottom board, which are in parallel. The groove of the heat radiation bottom board, which is formed through the structure, can be made wider, the bottom board manufacture is simple, and the heat radiation efficiency is high.
Description
Affiliated technical field
The utility model relates to the power electronics heat abstractor, especially the radiator of high-power electronic device.
Background technology
High-power electronic device radiator is in the past mostly used the cast aluminium casting forming.Because the mould structure and the restriction in life-span, thus between the radiator fin of Gou Chenging apart from broad, total cooling surface area of integral body is also less, the effect of heat radiation is relatively poor.In addition, also have a kind of the heat radiation aluminium flake to be contained in the narrow groove of radiating bottom plate, with the rolling process heat spreader structures that aluminium flake and radiating bottom plate compress that will dispel the heat.Though inter fin space is from narrower, fin surface is long-pending also bigger, is not apt to do the not only narrow but also dark groove that embeds the heat radiation aluminium flake.Therefore, this kind radiator processing difficulties, thermal resistance also are difficult for reducing.
Summary of the invention
In order to overcome above-mentioned defective, realize that a kind of inter fin space is little, total cooling surface area is big, again the radiator of handling ease.The utility model is made up of fin, radiating bottom plate and stationary pipes; Rectangular channel parallel to each other is arranged on the radiating bottom plate, packs in the same groove of radiating bottom plate in pairs in the end of per two fin, and stationary pipes is installed between two fin ends in the radiating bottom plate groove of packing into; Stationary pipes is pressed into by external force, and groove both sides size is placed restrictions on and is extruded, and produces the resilience force distortion, and the end sides of two fin tightly is pressed against on the radiating bottom plate cell wall parallel to each other.
Because the utility model has adopted by external force and has been pressed into stationary pipes, stationary pipes is out of shape compresses fin, reaches the thermal resistance minimum between fin and the radiating bottom plate.Therefore, the groove on this radiator heat-dissipation base plate can do broad, make simple, the radiating efficiency height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail
Fig. 1 is a cross section of the present utility model schematic diagram.
Fig. 2 is to use the cross section of the present utility model schematic diagram of two stationary pipes.
Among the figure: 1, fin, 2, stationary pipes, 3, radiating bottom plate, 4, the radiating bottom plate groove.
Embodiment
As shown in Figure 1, the utility model is made up of aluminum alloy heat sink 1, aluminium alloy radiating bottom plate 3 and stainless steel stationary pipes 2; Radiating bottom plate groove 4 is arranged on the radiating bottom plate 3, packs in the same radiating bottom plate groove 4 of radiating bottom plate 3 in pairs in the end of per two fin 1, and stainless steel stationary pipes 2 is pressed between two fin 1 ends in the radiating bottom plate groove 4 of packing into; Stainless steel stationary pipes 2 is pressurizeed between two fin 1 ends by board-like instrument, is subjected to radiating bottom plate groove 4 both sides sizes to place restrictions on and be extruded, and produces the resilience force distortion, and the end sides of two fin 1 tightly is pressed against on the cell wall of radiating bottom plate groove 4.Radiating bottom plate groove 4 is rectangular channels parallel to each other, and two fin 1 are pressed against can be parallel to each other behind the radiating bottom plate groove 4, produces better heat radiating effect.In addition,, can do radiating bottom plate groove 4 darker, adopt 2 distortion of two stainless steel stationary pipes to compress the end of fin 1, increase heat transfer area, as shown in Figure 2 in order to realize more powerful heat radiation needs.
Claims (2)
1, a kind of radiator, this radiator is made up of fin and radiating bottom plate; It is characterized in that: it also has stationary pipes; On the described radiating bottom plate groove being arranged, packs in the same groove of radiating bottom plate in pairs in the end of per two fin, and stationary pipes is installed between two fin ends in the radiating bottom plate groove of packing into; Stationary pipes is pressed into by external force, and groove both sides size is placed restrictions on and is extruded, and produces the resilience force distortion, and the end sides of two fin tightly is pressed against on the cell wall of radiating bottom plate.
2, radiator according to claim 1 is characterized in that: the groove of described radiating bottom plate is a rectangular channel parallel to each other.
