Embodiment
Below, with reference to the description of drawings embodiments of the present invention.In the following description, to identical or similar constitutive requirements, in a plurality of accompanying drawings, annotate and add suitable suffix with same tag or on same tag and represent.
Execution mode 1
Fig. 1 (a)～(c) is the radiator of present embodiment 1, represents its integral body with 2.This radiator 2 has the plate-shaped fins 6 (6a, 6b, 6c, 6d) that tabular substrate 4 and a plurality of (being 4 in the illustrated example) are approximately perpendicular to substrate 4.Substrate 4 has tabular surface (the 1st face) 4a that mounting the heater (with the heater hot link) that do not show of figure.Plate-shaped fins 6 (6a, 6b, 6c, 6d) in parallel to each other devices spaced apart, be supported on the substrate 4 by tabular surface (the 2nd face) 4b with tabular surface 4a opposition side.In the following description, substrate 4 is positioned at the position parallel with the XY face, and as the Y direction, each fin 6 is positioned at the position parallel with the XZ face the orientation of fin 6a～6d.
Each fin 6 is lotus root (lotus rhizome) shape parts, has the roughly [8 of Y direction extension of a plurality of edges.When the action of radiator 2, cold-producing medium is flowed by hole 8 court+Y directions according to the order of fin 6a, 6b, 6c, 6d.Cold-producing medium for example can adopt the gas in the liquid of cooling water, anti-icing fluid (ethylene glycol) etc. or cold wind, fluorine Lyons etc.In order to prevent freezing medium leakage, usually, along the flow of refrigerant direction, be provided with pipe arrangement, and be provided with the top of fin 6 and the plate of side seal, so that cold-producing medium flows through in the upstream and the downstream of radiator 2.But, under the situation of air-cooled type, also can cold wind be flow through in the pipe arrangement, and fin 6 is exposed in the atmosphere.
The substrate 4 of radiator 2 and fin 6, for example be that the rectangular-shaped porous part (lotus root shape porous member) 10 (Fig. 1 (d)) that is made of metals such as copper, magnesium, aluminium, silicon is carried out cut, the groove 11 (11a, 11b, 11c) that processes with XZ parallel plane more than 1 or 1 (in the example of Fig. 1 (d) 3) forms.In addition, as previously mentioned, the tabular surface 4b of substrate 4, its part forms the bottom surface (outward appearance of radiator 2) of groove 11, and a part forms the imaginary boundary of fin 6.
In addition, radiator 2 for example is used for cooling off CPU, the MPU (following execution mode too) of computer, mainframe computer.
Below, the formation method of radiator 2 is described with reference to Fig. 2, Fig. 3.
First with following known method (among the application, be called the metal freezing method, particular content is for example disclosing in the Japanese kokai publication hei 10-88254 communique), form the metal that has a plurality of tubulose through holes.Fig. 2 forms the casting device that this porous matter metal is used.This casting device 12 has the crucible 14 of accommodating metal derby.Twining the coil 16 of heating crucible 14 usefulness at the peripheral part of crucible 14.Coil 16 is applied high-frequency current, with the metal derby fusion in the crucible 14.At the downside of crucible 14, setting the mould 20 that the base has cooling end 18, by being installed in the open and close valve 22 of crucible 14 lower ends, the metal of molten condition is injected in the mould 20.
Crucible 14 and mould 20 are configured in the closed container (figure does not show), and the gas that remains predetermined pressure in filling in container.This gas and metal, under isobaric gaseous environment, metal-gas is that state diagram has eutectic point.For example, if metal is copper, aluminium, then gas is selected hydrogen, nitrogen etc.In the metal freezing method, utilize following phenomenon, that is, if temperature than the temperature height of eutectic point, then gas atom dissolves in the metal of liquid condition; If temperature is lower than the temperature of eutectic point, then gas atom does not dissolve in the metal of solid state, exist as gas,
In this casting device 12, at first closed container is placed in the isobaric gaseous environment, and the packaged of metal 24 gone in the crucible 14 (Fig. 3 (a)).In open and close valve 22 closing state, coil 16 is applied high-frequency current, make the piece fusion of the metal 24 in the crucible 14.As a result, be melted the metal absorption of state with the gas of its concentration and the corresponding amount of pressure.Then, open open and close valve 22, make motlten metal 26 flow into mould 20 (Fig. 3 (b)).Owing to be provided with cooling end 18 in the bottom of mould 20, so, temperature gradient become from mould 20 bottom-up square.As a result, metal solidifies towards the top from the bottom of mould 20.In the process of setting of motlten metal, produced eutectic reaction, promptly from the motlten metal that is dissolving gas atom, isolate the metal of solid state and the gas of gaseous state.Because the path of gas is the hole, form towards the top from the bottom of mould 20, so, can obtain the porous matter metal (porous material) 30 (Fig. 3 (c)) that inside has formed [28.In addition, except metal, also can use semiconductor is silicon, obtains porous material with above-mentioned metal freezing method.In this case, following operation is applicable to the porous material that constitutes with silicon.
Then, for example, the porous matter metal 30 that obtains with the metal freezing method is formed cuboid, finished porous part 10 (Fig. 1 (d)) with slotting cutter etc.Use for example discharge lines processing method again, on this porous part 10, form groove.Specifically, shown in Fig. 1 (d), to porous part 10, in the imaginary area 32a corresponding (being roughly with the bearing of trend in hole 8 that 90 degree intersect) top, the discharge lines that configuration is extended along directions X (scheming not show) with the groove 11a that will form.Then, this discharge lines court-Z direction is moved, arrive apart from the distance of following (4a is corresponding with tabular surface) is the upper side position of substrate 4 thickness of radiator 2 usefulness always.Then, the pull-up of court+Z direction like this, has formed groove 11a.The thickness of groove 11a (Y direction length) is the line footpath of line at least.Remaining 2 imaginary area 32b, 32c are carried out above-mentioned action repeatedly, formed groove 11b, 11c.Like this, obtained having the radiator 2 (from the character of metal freezing method, not only can form the hole 8 of perforation on fin 6, also can form the hole (seeing Fig. 1 (c)) that does not connect, it is circular that the section shape of through hole does not limit yet) of lotus root shape fin 6a～6d.
Usually, the value of long-pending Sp * hp of the contact area of hole and cold-producing medium (heat transfer area) Sp and the convective heat transfer rate hp from the hole inner face to cold-producing medium is big more, and the cooling capacity of porous part is high more.For the fin 6 that adopts in the present embodiment, in order to improve its cooling capacity, the method for taking is, the number in hole 8 increased and Sp is increased, and in addition, thereby reduces the diameter in hole 8 and flow velocity by the cold-producing medium in the hole increased hp is increased.
In addition, according to Japanese kokai publication hei 10-88254 communique disclosed method, can make the aperture is the scope of tens of μ m～number μ m, the lotus root shape porous metals that voidage is set arbitrarily.According to this manufacture method, can be easily and lotus root shape porous metals are provided at low cost.
In addition, as porous part, adopting through hole is not the structure of the foaming material (foaming metals such as aluminium for example foam) of tubulose, is also contained in the scope of the invention.But, the porous part 10 of lotus root shape, promptly adopt the parts of lotus root shape fin 6, the cold-producing medium of adjacent holes does not collaborate or the cold-producing medium that flows through certain hole is not shunted owing to flow through, so, not because of the pressure loss of collaborating, shunting produces, the low radiator of the pressure loss generally can be provided, and is more satisfactory from this point.
Especially, in the porous part 10 of lotus root shape, the length in Y direction hole is about 10mm among Fig. 1 (c), and the thickness of Y direction fin 6 is below the 10mm, and like this, the number in the hole 8 of perforation fin 6 is many, improves the cooling capacity of fin 6.
As mentioned above, in the present embodiment, on porous part 10, cut out groove 11, formed substrate 4 and fin 6, so, different with above-mentioned structure before, do not need operation that substrate and a plurality of fins are engaged one by one, the result can boost productivity.
In addition, when bonding to fin on the substrate with bonding agent like that before, the heat conduction rate variance of connecting portion is not easy to improve heat dissipation characteristics.And in the radiator 2 of present embodiment, because fin 6 and substrate 4 are integrally formed, so can improve heat dissipation characteristics.
In addition, the radiator of 2 fins is arranged, be also contained in the scope of the present invention for a groove.In addition, the method for the shape of each fin, the shape of substrate (shape that comprises the 1st and the 2nd 4a, 4b), cut groove does not limit the present invention.
Fig. 4 (a) and (b) are with the porous part cutting, obtain the other method of present embodiment radiator.In this method, be ready to the above-mentioned rectangular-shaped porous part 10 that similarly forms '.Then, make discharge lines along porous part 10 ' imaginary plane 34, with respect to porous part 10 ' move, thereby make roughly the same radiator 2 ', 2 ".The line footpath of employed line is different with above-mentioned cutting process, and is more much smaller than the width (Y direction length) of the groove that will form.Specifically,, discharge lines is placed on the lower position that is equivalent to the substrate 4 ' thickness of radiator 2 ' usefulness apart from the top, 1 from a side of Y direction) make line court+Y direction move preset distance (for example more than the 1mm, preferably about 10mm).Then, 2) discharge lines court-Z direction is moved, arrive apart from following distance is the upper side position of radiator 2 " substrate 4 of usefulness " thickness always.Make discharge lines court+Y direction move the distance that is equivalent to groove width again.Then, 3) discharge lines court+Z direction is moved, arrive apart from top distance is the lower position of the substrate 4 ' thickness of radiator 2 ' usefulness always.Repeatedly 2 times 1 again)～3) action after, discharge lines court+Y direction is moved, like this, from porous part 10 ' obtained radiator 2 ', 2 ".
According to this cutting method, can form 2 radiators simultaneously, therefore, compare with the method for above-mentioned cutting slot, boost productivity more.
Fig. 5 is the radiator of present embodiment 2, represents its integral body with 2A.In the radiator 2A of present embodiment, on the 1st 4a of the opposition side of support fin 6 sides of substrate 4, also engaged the good plate (the 2nd substrate) 40 of heat conductivity.Heater is positioned on the substrate 40 (the 1st 4a of substrate 4 and heater hot link).
When the base material of making radiator 2A was porous part, hole 8 was not a tubulose sometimes, but the 1st 4a of the path of cold-producing medium and substrate 4 is communicated with by hole 8.At this moment, go up, make the radiator action as if the 1st 4a that heater is positioned in substrate 4, then cold-producing medium leaks from the 1st 4a.For this reason, in the present embodiment,, can guarantee the sealing of radiator 2A by substrate 40 is set.As a result, can improve the rate of finished products of porous part.
Execution mode 3
Fig. 6 represents the execution mode 3 of radiator of the present invention.In the radiator 2B of present embodiment, the through hole 8B of fin 6B is not parallel to Y direction (orientation of fin 6B), but extends obliquely.Therefore, fin 6B compares with the fin 6 of the execution mode 1 with same thickness, and heat transfer area S increases, and the result can improve the cooling capacity of radiator 2B.
The fin 6B of radiator 2B, be on porous part, along obtaining with the non-orthogonal in fact imaginary area of the bearing of trend of [(the parallel plane imaginary area of XZ of the angle (acute angle) following) formation groove with become about 90 degree with respect to this bearing of trend.
In addition, among Fig. 6, be that the situation that bearing of trend to [has departed from the Y direction is described, still, as the Y direction, the situation of the formation deviation in driction XZ face of groove is also contained in the present embodiment.
Fig. 7 (a) and (b) are radiators of present embodiment 4, represent its integral body with 2C.In the above-described embodiment, be on porous part, the grooving of retention substrate thickness landform, therefore, each fin is to interconnect by substrate.And in the radiator 2C of present embodiment, be above the Z direction of porous part 10 to following formation through slot 41, a plurality of fin 6C are being supported by the sidewall 42 that is formed on a side at directions X.That is, fin 6C and sidewall 42 are integrally formed with porous material.Below the Z of fin 6C direction, engaging the good plate of heat conductivity (substrate) 40.Heater is positioned on the substrate 40.During radiator 2C action, under the situation about being communicated with below by hole 8 of refrigerant passage and fin 6C, substrate 40 also has the sealing function that prevents freezing medium leakage.In addition, sidewall 42 also has the function of the wall that constitutes refrigerant flow path, so, when manufacturing has the cooling device of radiator 2C, have the advantage that can dispense the work of making pipe arrangement.
The manufacture method of radiator 2C is identical with the manufacture method of the radiator 2 of Fig. 1.That is, on rectangular-shaped porous part 10, in the directions X left side of the imaginary area 32C corresponding, the discharge lines that configuration is extended along the Z direction with the groove that will form.This discharge lines court+directions X is moved, and arrive apart from the distance on the directions X right side is the leftward position of sidewall 42 thickness of radiator 2C always.Then, court-directions X moves, and forms a through slot 41.After having formed a plurality of through slots, this porous part 10 is joined on the substrate 40.
The orientation of fin 6C, can with execution mode 1 similarly, be parallel to the bearing of trend of tubulose through hole 8 in fact, also can with execution mode 3 similarly, acutangulate with above-mentioned bearing of trend.Under latter instance, the heat transfer area S of through hole and cold-producing medium increases, and can improve the cooling capacity of radiator 2C.
In the present embodiment, a plurality of fin 6C are connecting by sidewall 42 that (in other words, a plurality of fin 6C are by the side adjacent with the composition surface of substrate 40, supporting by sidewall 42), therefore, can once a plurality of fin 6C be bonded on the substrate 40, can boost productivity.
Fin 6C and sidewall 42 are being installed in the pipe arrangement that constitutes cooling flowing path, when the wall of pipe arrangement constitutes substrate 40 (heater is positioned on the pipe arrangement wall), are being also contained in the scope of the present invention.This structure also has the above-mentioned effect of present embodiment.
Sidewall (directions X) needn't only be located at a side, and sidewall 42R, 42L also can be as the radiator 2D of Fig. 8 be set in both sides.Through slot 41D with adjacent fins 6D separates forms with for example slotting cutter.In addition, in order to obtain the above-mentioned effect of present embodiment, as long as sidewall is connected to the adjacent fin of looking younger, sidewall also not necessarily will be formed on the whole side (side's side of directions X).For example, also can as the radiator 2E of Fig. 9 (a), sidewall 42a, 42b, 42c (at this moment, the through slot 41E that adjacent fins 6E is separated forms staggered) alternately be set in the right side and the left side of directions X.
As Fig. 7, shown in Figure 8, when being provided with the sidewall that supports whole fins, the heater on being positioned in substrate 40, all right other heater of mounting on sidewall can provide the radiator that can corresponding come from the heat of side.In order to ensure the sealing of radiator, the substrate of also can on sidewall, rejoining.
