Embodiment
Fig. 1 is the schematic diagram of the electronic installation of one embodiment of the invention.Fig. 2 be Fig. 1 the second radiator in rotate time schematic diagram.Fig. 3 is the stereogram of the heat abstractor of Fig. 2.Please refer to Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, electronic installation 1 is for example a server, and it comprises that one has circuit board 10 and a heat abstractor 100 of thermal source 12.It should be noted that, for making view succinct, Fig. 1, Fig. 2 and Fig. 3 omit cabinet and the inner electronic component thereof of electronic installation 1.
In addition, the circuit board 10 of the present embodiment can be the motherboard being assembled in server, and thermal source 12 is for example central processing unit (CPU) or image processor (GPU) on motherboard.After heat abstractor 100 is arranged on thermal source 12, heat abstractor 100 first adsorbs the heat of thermal source 12 with heat exchange pattern, and cooling blast f brings to the external world in thermal convection mode by the heat of being adsorbed of heat abstractor 100 more rapidly.It should be noted that, for making view clear, the heat abstractor 100 clipped elements of Fig. 3.
Hold above-mentionedly, heat abstractor 100 comprises that one first radiator 110, one second radiator 120, wear part 130, at least one air inlet 142, an air outlet 144 and the gas channel 146 between air inlet 142 and air outlet 144.The first radiator 110 is fixed on thermal source 12, and thermal source 12 is positioned at gas channel 146.The second radiator 120 has the multi-disc radiating fin 122 being arranged in parallel, and multiple passage 122a is between these radiating fins 122.The second radiator 120 is arranged on the first radiator 110 and with the first radiator 110 and contacts.The heat that thermal source 12 produces can be passed on the radiating fin 122 of the second radiator 120 by the first radiator 110.Wear part 130 and wear between the first radiator 110 and the second radiator 120, wherein the second radiator 120 can be pivoted via wearing part 130, and the second radiator 120 can be rotated with respect to the first radiator 110.
Particularly, the air inlet 142 of the present embodiment, air outlet 144 can be installed on the scope surrounding on circuit board 10 and be formed by a wind scooper 20 with gas channel 146, but the present invention is not as limit.Accordingly, air inlet 142 can be guided cooling blast f and be entered to gas channel 146 and flow to air outlet 144 along a flow direction d1, and wherein cooling blast f can be by fan (not illustrating) or outside air and produced.In the time that the second radiator 110 turns to a service position, the bearing of trend d2 of radiating fin 122 is consistent with the flow direction d1 of cooling blast f that is positioned at gas channel 146.
Say further, the part 130 that wears of the present embodiment is for example a screw (screw) or a pin (pin), and wears part 130 and be embedded in the second radiator 120 and be fixed on the first radiator 110.Therefore, wear and penetrate part 130 and there is a tightening state or and separate solid state.When wearing while penetrating part 130 in tightening state, the relative position locking (as shown in Figure 1) of the first radiator 110 and the second radiator 120.Otherwise, penetrate part 130 in the time separating solid state when wearing, the second radiator 120 can rotate (as shown in Figure 2) with respect to the first radiator 110.In other words, the second radiator 120 can be rotated as rotating shaft using the central shaft that wears part 130.
In the time that the heat of thermal source 12 is conducted and is passed to radiating fin 122 by the first radiator 110 and the second radiator 120, because the second radiator 120 can rotate with respect to the first radiator 110, therefore the angle of the bearing of trend d2 of these radiating fins 122 of capable of regulating and the flow direction d1 of cooling blast f, so that the bearing of trend d2 of these radiating fins 122 can be parallel to the flow direction d1 of cooling blast f.In other words, these passages 122a can be parallel with the flow direction d1 of cooling blast f.By this, the heat energy on the second radiator 120 is pulled away rapidly, to improve the radiating efficiency of thermal source 12.Therefore, heat abstractor 100 has preferably radiating effect.In addition,, because the second radiator 120 can be rotated by wearing part 130, therefore can be applicable to the electronic installation of different type of machines.Configuration, can make heat abstractor 100 have the advantage of sharing part by this, and then can reduce the production cost of the electronic installation 1 of this heat abstractor 100 of application.
In addition, first radiator 110 of the present embodiment and the second radiator 120 cover thermal source 12 in the orthographic projection of circuit board 10.Therefore, can make the thermal source 12 of circuit board 10 there is larger heat transfer area, contribute to accelerate the radiating rate of thermal source 12.
In addition, wear part 130 also can move apart in the first radiator 110 and the second radiator 120.In detail, wear and penetrate part 130 and more can there is a disassembly status.When wearing while penetrating part 130 in disassembly status, the second radiator 120 can separate with the first radiator 110, and unloading from electronic installation 1.Therefore, after wearing and penetrating part 130 and separate on the second radiator 120, and the second radiator 120 is separated with the first radiator 110.By this, can be convenient to maintenance personal detects or changes.
Please refer to Fig. 3, heat abstractor 100 more comprises a flexible heat-conducting layer 150, and it is for example heat-conducting cream, thermal grease or cooling pad.Flexible heat-conducting layer 150 is configured between the first radiator 110 and the second radiator 120 and is full of the space between the first radiator 110 and the second radiator 120.Adsorb after the heat of thermal source 12 at the first radiator 110, flexible heat-conducting layer 150 can conduct to heat the second radiator 120 fast.By this, also can improve the radiating effect of heat abstractor 100.
In sum, the second radiator of the present invention can rotate with respect to the first radiator by wearing part.By this, can make the bearing of trend of radiating fin of the second radiator and the flow direction of cooling blast consistent, so that heat abstractor has preferably radiating effect.In addition, heat abstractor can be applicable in the electronic installation of different type of machines, can make heat abstractor have the advantage of sharing part, and then can reduce the production cost of electronic installation.In addition, heat abstractor more can comprise flexible heat-conducting layer, also contributes to improve radiating efficiency.
Although the present invention discloses as above with embodiment; so it is not in order to limit the present invention; under any, in technical field, have and conventionally know the knowledgeable; without departing from the spirit and scope of the present invention; when doing a little change and retouching, therefore protection scope of the present invention is when being as the criterion of defining depending on accompanying claim.
