Below use description to form the material of pump case 101.As mentioned above, first cap 111 is arranged between rotor 103a and the stator 103b.If first cap 111 is made the danger of the operation of the rotor 103a that then may make a difference by conductive material.If first cap 111 is by the metallic material manufacturing, pump 100 may become heavy so.Like this, according to one embodiment of present invention, at least the first cap 111 of pump case 101 preferably is formed from a resin.
The basic portion 121 of main body has relatively complicated structure.Thereby, if the basic portion of main body 121 make by metallic material, so transfer mold be pressed into this with and manufacture cost may be very high.If the basic portion of main body 121 is made by metallic material, pump 100 may become heavy so.Therefore, according to one embodiment of present invention, the basic portion 121 of main body is made by resin material equally.
In the present embodiment, at least a portion of pump case 101 (just, parts) comprising: for instance, the basic portion 121 of main body and first cap 111, be formed from a resin, this resin comprise following one of at least: metal charge, the packing of material and packing with material of the vapor transmission rate lower than resin with coefficient of linear expansion lower than resin.Make like this can obtain to be easy to make, cost is low, in light weight and can suppress by evaporation, spill or the like the pump 100 that the liquid coolant that causes reduces.Therefore, can obtain the pump 100 that can optimally cool off for a long time.
More particularly, a lot of metals not only have higher conductivity, and have lower coefficient of linear expansion and vapor transmission rate.Therefore, the basic portion 121 of main body and first cap 111 are by the resin manufacture that comprises this types of metals packing.This feasible basic portion 121 of main body and first cap 111 that can obtain comparing lower coefficient of linear expansion with situation about only being formed from a resin.Thereby, can realize reducing the difference of first cap 111 and the coefficient of linear expansion of the basic portion 121 of main body, and the difference of the basic portion 121 of main body and the coefficient of linear expansion of heat absorption plate 122.Thereby, can suppress spilling of the gap of liquid coolant by formation between the gap that forms between first cap 111 and the basic portion 121 of main body and the basic portion 121 of main body and the heat absorption plate 122, these two kinds of gaps all are that the difference owing to coefficient of linear expansion forms.
In addition, because the basic portion 121 of main body and first cap 111 made by the resin that comprises this types of metals packing, so, compare with first cap 111 with the main body substantial section 121 that only is formed from a resin and to have lower vapor transmission rate.Thereby, can suppress the evaporation of liquid coolant from pump case 101.
In addition, because the basic portion 121 of main body and first cap 111 be by the resin manufacture that comprises this types of metals packing, show higher heat-conducting effect so compare with the structure of first cap 111 with the basic portion 121 of the main body that only is formed from a resin.Thereby the heat that produces in CPU 31 can be conducted fast to the liquid freezing mixture.
In addition because the basic portion 121 of main body and first cap 111 made by the resin that comprises this types of metals packing, so with only compare by the situation of metallic material manufacturing, the weight of pump case 101 is lighter.
Go for this types of metals packing such as copper filler material, aluminium packing or aluminum alloy packing.
When the basic portion 121 of main body and first cap 111 are made by the resin that comprises the metal charge with coefficient of linear expansion lower than resin, the basic portion 121 of main body and first cap 111 will have the coefficient of linear expansion lower than resin.This can reduce the difference of coefficient of linear expansion between first cap 111 and the basic portion 121 of main body, and the difference of coefficient of linear expansion between basic portion 121 of main body and the heat absorption plate 122.Thereby, can suppress the gap of liquid coolant by formation between the gap that forms between first cap 111 and the basic portion 121 of main body and the basic portion 121 of main body and the heat absorption plate 122 and spill.
In addition, when the basic portion 121 of main body and first cap 111 are made by the resin that comprises the metal charge with vapor transmission rate lower than resin, the basic portion 121 of main body and first cap 111 will have vapor transmission rate lower when only being formed from a resin than these elements 121 and 111.Thereby, can suppress liquid coolant from pump case 101 evaporations.Thereby the heat that produces in CPU 31 can conduct to liquid coolant by for example heat absorption plate 122 apace.
In addition, when the basic portion 121 of main body and first cap 111 by comprising metal charge with coefficient of linear expansion lower than resin, or the resin with metal charge of the vapor transmission rate lower than resin is when making, only compared by the situation that metallic material is made with first cap 111 with the basic portion 121 of main body, the weight of pump case 101 can be lighter.
Be not only metal, and most of carbon and stupalith, its coefficient of linear expansion and vapor transmission rate are all lower.Thereby, any by material with coefficient of linear expansion lower than resin, or the made packing with vapor transmission rate lower than resin, such as metal charge, carbon packing, semiconductor packing or ceramic packing, all can be fit to use.The example of pottery packing includes, but are not limited to or is subject to alumina (aluminium oxide) packing or aluminium nitride.
For the resin that comprises packing, for example, can use polycarbonate (PC) or ABS resin.State in the use under the situation of resin, can keep pump chamber 101 desired intensity.
Below be various materials coefficient of linear expansion separately:
Semiconductor silicon: 3ppm/ ℃
(aluminium oxide): 7ppm/ ℃ on pottery
Carbon: 2 to 7ppm/ ℃
Copper: 17ppm/ ℃
Aluminium: 22ppm/ ℃
Polycarbonate (PC): 70ppm/ ℃
ABS resin: 74ppm/ ℃
On the other hand, in order optimally to cool off CPU 31, heat absorption plate 122 is preferably made by the metallic material with high thermal conductivity coefficient.As an embodiment, heat absorption plate 122 is become by the copper that for example has high thermal conductivity coefficient.Because in the present embodiment, when housing 110 formed by being divided into basic portion 121 of main body and heat absorption plate 122, heat absorption plate 122 can be selectively by the high thermal conductivity coefficient made.
In addition, second cap 112 is preferably made by metallic material, with spilling and influence of evaporation that relevant second cap 112 of reinforcement inhibition liquid coolant is taken place.According to an embodiment, second cap 112 is made by for example aluminum or aluminum alloy material.
By adopting following assemble mechanism, pump 100 is mounted to the diapire 11a of first shell 10, cover CPU 31 with top from CPU 31.Recess 141 is arranged in pump case 101 four bights separately.The diapire (bight of heat absorption plate 122) that limits recess 141 has through hole 142, is used to allow cylindrical insert 143 to pass.Each cylindrical insert 143 all has the protuberance 143a that edge substantially horizontal along the circumferential direction on top is projected into the outside.In addition, cylindrical insert 143 has the slot part 143b that forms along circumferencial direction.
Conduction grease (not shown) is imposed on the upper surface of IC chip 33, and the heat absorption surface 122a of pump case 101 is arranged on the position relative with IC chip 33.The screw 146 that passes cylindrical insert 143 is screwed in the protuberance 17 that forms on printed circuit board (PCB) 30.Thereby cylindrical insert 143 is fixed to protuberance 17, pump 100 by the elastic compression of helical spring 144 on IC chip 33.Thereby IC chip 33 is thermally coupled to the heat absorption surface 122a of pump case 101 by the conduction grease.
In portable computer 1, pump 100 is fixed on the printed circuit board (PCB) 30, thereby makes the center of center (center of the surperficial 122a that absorbs heat) the aligning IC chip 33 of pump case 101.Yet, the misalignment of the center of impeller 102 (running shaft 102a) and pump case 101.Therefore, the misalignment of the center of IC chip 33 and the impeller 102 relative with it, and pump case 101 is between between them.This arrangement makes liquid coolant can absorb the heat as much as possible of IC chip 33.That is, according to one embodiment of present invention, IC chip 33 is relative with the position that liquid coolant flows through fast, simultaneously pump case 101 is inserted between them, so that liquid coolant absorbs heat as much as possible.What known is, being flowing in from impeller 102 centers of the liquid coolant that rotation produced by rotor 103a will become fast more when far away more.Therefore, use said structure, the more heat of IC chip 33 has been absorbed into liquid coolant.
As shown in Figure 3, thermal radiation portion 50 have thermal radiation portion main body 51 and with a plurality of thermal radiation plates 57 of thermal radiation portion main body 51 thermal couplings.Thermal radiation portion main body 51 is made of pipeline (piping), and liquid coolant flows by this pipeline.Thermal radiation portion main body 51 has coolant entrance 54 and coolant outlet (when the paper that passes Fig. 3 is seen, being set at the depth side of coolant entrance, although it is not illustrated), and surface current is moving inwards thereby make freezing mixture.
According to one embodiment of present invention, thermal radiation portion main body 51 is made by the pipeline of U-shaped basically.An opening end of pipeline is as coolant entrance 54, and another opening end of pipeline is as coolant outlet.Therefore, the pipeline of thermal radiation portion 50 (thermal radiation portion main body 51) has constituted the part of peripheral passage 60 (following will being explained in more detail it).
The pipeline (thermal radiation portion main body 51) that peripheral passage 60 has first pipeline 61, second pipeline 62 and belongs to thermal radiation portion 50.That is, thermal radiation portion main body 51 is simultaneously as thermal radiation portion 50 and peripheral passage 60.First pipeline 61 is connected to the outer pipe 132 of pump 100 coolant entrance 54 of thermal radiation portion 50.Second pipeline 62 is connected the inlet duct 131 of pump 100 and the coolant outlet of thermal radiation portion 50.Thereby liquid coolant is through first and second pipeline 61 and 62, and circulation between pump 100 and thermal radiation portion 50.
The work of cooler 40 below will be described.
In the process of using portable computer 1, the IC chip 33 of CPU 31 produces heat.The heat that IC chip 33 produces is sent to pump case 101 by the heat absorption surface 122a of pump 100.The recess 113 of pump case 101 (pump chamber 118 and hopper 119) is filled with liquid coolant, so that liquid coolant absorbs the heat that much is sent to pump case 101.
When portable computer 1 start, electric current is delivered to the stator 103b of motor 103.Thereby, between stator 103b and rotor 103a, produce torque, thereby rotor 103a impeller 102 is rotated.Follow the rotation of impeller 102, the liquid coolant in pump chamber 118 is applied in pressure, and is extracted out from outer pipe 132, simultaneously, imports thermal radiation portion 50 by first pipeline 61 from coolant entrance 54.Flow to the coolant outlet side by heat exchange heated liquid freezing mixture from coolant entrance 54 in pump case 101, in this process, the heat of IC chip 33 is absorbed by liquid coolant and is sent to thermal radiation plate 57.
In the process of using portable computer 1, rely on the rotation of the impeller 72 of electric fan 70, cool air flows to thermal radiation portion 50 from the outlet 71a of fan hub 71.Cool air 57 passes between contiguous mutually thermal radiation plate 57.Thereby, be cooled such as the parts of thermal radiation plate 57 and thermal radiation portion main body 51.Then, when cool air flowed like this, the most of heat that is sent to thermal radiation plate 57 and thermal radiation portion main body 51 was discharged into the outside of first housing 10 from relief opening 15.
The liquid coolant of cooling imports the inlet duct 131 of pump case 101 by second pipeline 62 in thermal radiation portion 50.Liquid coolant is got back to hopper 119 from inlet duct 131.When being inhaled into pump chamber 118, the liquid coolant that returns hopper 119 like this absorbs the heat of IC chip 33 once more.
