The embodiments of the present invention are described below with reference to the drawings. However, the present invention is not limited to the interpretation by the description of the following embodiments. In addition, in the following description, the same reference numerals are used for the same configuration.

First, define the terms used in the following description. The so-called "metal fiber" refers to a fiber whose main component is metal, for example, "copper fiber" refers to a fiber whose main component is copper. Furthermore, when a metal is the main component, it contains unavoidable impurities, and it is also possible to contain a certain amount of components other than the metal before the effect of the present invention is not impaired. In addition, the "thermal conductivity (W/(m·K))" is a value measured by the laser flash method (for example, a laser flash thermal constant measuring device "TC7000" manufactured by ULVAC-RIKO Co., Ltd.). Furthermore, the so-called "average fiber diameter" refers to the calculation of the cross-sectional area perpendicular to the long side direction of the metal fiber based on the vertical cross-section of the metal fiber sheet taken by the microscope, and the calculation has the same area as the cross-sectional area The diameter of the perfect circle, and the arithmetic mean of the derived area diameter. Here, the plural number of places can be set to 20 places, for example. Furthermore, the so-called "average fiber length" refers to the measurement of the length of the fibers in the longitudinal direction of a plurality of randomly selected fibers in the microscope image, and then the arithmetic average of the values is calculated. In addition, when the fiber is not linear, the length along the curve of the fiber is set. Here, the plural branches can be set to, for example, 20 branches. Furthermore, the so-called "occupation rate" refers to the proportion of fiber part in the volume of the fiber sheet, which is calculated from the basis weight, thickness and true density of the fiber from the fiber sheet. Here, when the fiber sheet contains multiple types of fibers, by using the true density value reflecting the composition ratio of each fiber, the occupation rate can be calculated. (Accumulation rate (%))=(fiber sheet basis weight)/((fiber sheet thickness)×(true density))×100. Here, the term "sheet thickness" refers to the arithmetic average of a terminal drop-type film thickness meter (such as the "digital gauge ID-C112X" manufactured by Mitutoyo Co., Ltd.) using air to measure, for example, the measurement point of a metal fiber sheet value. The so-called "homogeneity" means that the electrical properties, physical properties, and air permeability properties of the sheet made of fibers have little variation within the sheet. The index of homogeneity can be, for example, the coefficient of variation (CV (Coefficient of Variation) value) ^{per 1 cm 2 of the basis weight prescribed by JIS Z8101.} The so-called "void ratio" refers to the proportion of the portion where the voids exist relative to the volume of the fiber sheet, which is calculated from the basis weight and thickness of the fiber sheet and the true density of the fiber by the following formula. When the fiber sheet contains multiple types of fibers, by using the true density value that reflects the composition ratio of each fiber, the occupation rate can be calculated. (Porosity (%))=(1-(basic weight of fiber sheet)/((fiber sheet thickness)×(true density)))×100. The heating medium used in the temperature control unit of the present invention may be a gas or a liquid, and the related properties are not limited. That is, the heating medium used in the temperature control unit of the present invention may be a gas such as air, a liquid such as water or alcohol, or a fluorine-based compound such as hydrofluorocarbon or hydrofluoroether.

<Embodiment 1> Fig. 1 shows a partial cross-sectional view of the temperature control unit 1 of this embodiment. The temperature control unit 1 shown in FIG. 1 is provided with a temperature control mechanism 3 through which a heating medium passes, and a heating medium introduction port and a heating medium discharge port (not shown). In the temperature control mechanism 3, the heating medium is introduced from the outside through the heating medium introduction port, and the heating medium is discharged to the outside from the heating medium discharge port. In addition, in the heating medium introduction port, it is preferable to install a static mixer in order to cause the introduced heating medium to generate turbulent flow and diffuse. In addition, examples of the heating medium system include water, air, and fluorine-based solvents.

The temperature adjustment mechanism 3 is provided with: a metal fiber sheet 6 composed of metal fibers, a housing 5 that accommodates the metal fiber sheet 6 and is enclosed by a heat exchange plate 7, and a heat exchange plate 7; the heat exchange plate 7 is a main The surface is exposed to the outside, and the back surface of the one main surface is in contact with the metal fiber sheet 6 to perform heat exchange between the metal fiber sheet 6 and the outside.

The metal fiber sheet 6 may be composed of metal fibers alone, or may contain components other than metal fibers. The metal component of the metal fiber can be exemplified by copper, stainless steel, iron, aluminum, nickel, chromium, and precious metals. Among them, copper, stainless steel, and aluminum are preferred, and copper is more preferred. This is due to the excellent balance between the rigidity and plastic deformability of the copper fiber. In addition, the noble metal series can be exemplified by gold, platinum, silver, palladium, rhodium, iridium, ruthenium, and osmium. Furthermore, the components other than the metal fiber contained in the metal fiber sheet 6 may be exemplified such as: Poly-Ethylene Terephthalate (PET: Poly-Ethylene Terephthalate), Polyvinyl Alcohol (PVA: Poly-Vinyl Alcohol), Polyolefin, polyvinyl chloride (PVC: Poly-Vinyl Chloride), polyamide and acrylic, and organic substances that impart adhesion and support to fibrous materials. Especially when the metal fiber sheet 6 is a non-woven fabric in which a plurality of metal fibers are randomly intertwined, by containing any one or more of these organic substances, the shape maintenance and function performance of the metal fiber sheet 6 can be assisted or improved. .

In the metal fiber sheet 6, a plurality of adjacent metal fibers are preferably bonded. That is, in the metal fiber sheet 6, it is preferable that a plurality of metal fibers are physically fixed, and a bonding portion is formed between the plurality of metal fibers. The metal fiber sheet 6 can directly fix a plurality of metal fibers using the bonding portion, or can be fixed indirectly, and it is preferable to form a gap between at least a part of the plurality of metal fibers constituting the metal fiber sheet 6. The reason is that if such voids are formed in the metal fiber sheet 6, the introduction of the heating medium into the metal fiber sheet 6 described later is easier to implement. Furthermore, in the bonding part, if a plurality of metal fibers are sintered, the thermal conductivity and homogeneity of the metal fiber sheet 6 are stable, which is preferable. The voids formed between the plurality of metal fibers can also be formed by the intertwining of the metal fibers. In addition, the porosity of the metal fiber sheet 6 is preferably 5% or more and 99% or less, more preferably 10% or more and 98% or less. Furthermore, the thermal conductivity of the metal fiber sheet 6 is preferably 5 W/(m·K) or more.

Furthermore, the metal fiber sheet 6 is pulled down before the sheet-like structure, and may be a non-woven fabric in which a plurality of metal fibers are randomly intertwined, or a regular woven fabric or mesh material. Furthermore, the surface of the metal fiber sheet 6 may be flat or may be corrugated.

The basis weight of the metal fiber sheet 6 is preferably 10 g/m ² or more and 1000 g/m ² or less. If the basis weight of the metal fiber sheet 6 is set to 10 g/m ² or more, the cooling or heating effect can be improved; if the basis weight of the metal fiber sheet 6 is set below 1000 g/m ² , the weight of the metal fiber sheet 6 can be reduced .

However, if the average fiber diameter of the metal fiber of the metal fiber sheet 6 is less than 1 μm, the rigidity of the metal fiber is reduced, and agglomeration is likely to occur when the metal fiber sheet 6 is manufactured, which causes the thermal conductivity and homogeneity of the metal fiber sheet 6 to change. Is unstable. On the other hand, if the average fiber diameter of the metal fibers of the metal fiber sheet 6 exceeds 30 μm, the rigidity of the metal fibers is too high, and entanglement is difficult. Therefore, the average fiber diameter of the metal fibers of the metal fiber sheet 6 is preferably 1 μm or more and 30 μm or less, more preferably 2 μm or more and 20 μm or less. Furthermore, when the metal fiber sheet 6 is a non-woven fabric in which a plurality of metal fibers are randomly intertwined, in order to stabilize the thermal conductivity and homogeneity of the metal fiber sheet 6, the average fiber length of the metal fiber of the metal fiber sheet 6 is preferably 1 mm Above and below 10mm.

Furthermore, if the aspect ratio of the metal fibers of the metal fiber sheet 6 is less than 33, the metal fibers are not easily intertwined. On the other hand, if the aspect ratio of the metal fiber of the metal fiber sheet 6 exceeds 10,000, the homogeneity of the metal fiber sheet 6 decreases. Therefore, the length and width of the metal fiber is preferably 33 or more and 10,000 or less.

Furthermore, if the occupation rate of the metal fiber sheet 6 is less than 2%, the pressure loss when the heating medium is introduced is suppressed. On the other hand, the cooling or heating effect is reduced due to insufficient fiber amount. On the other hand, if the occupation ratio of the metal fiber sheet 6 exceeds 65%, the pressure loss when the heating medium is introduced increases. Therefore, the proportion of the metal fiber sheet 6 is preferably 2% or more, more preferably 4% or more, and more preferably 5% or more; preferably 65% or less, and more preferably 60% or less.

Furthermore, in order to improve the homogeneity of the metal fiber sheet 6, the CV value of the coefficient of variation of the basis weight ^{per 1 cm 2 of the metal fiber sheet 6 specified by JIS Z8101 is preferably 10% or less.}

The manufacturing method of the metal fiber sheet 6 is not limited to a specific method. The manufacturing method when the metal fiber sheet 6 is a mesh material or a woven cloth can be a plain weave made of metal wires crossing each other, or a metal wire arranged in a vertical direction and a metal wire arranged in a horizontal direction can be used. Above the branch is a woven weave that crosses across. Alternatively, weaving, flat weaving, or damask weaving can also be used. Alternatively, when the metal fiber sheet 6 is a mesh material, the metal wires may be welded in a warp-crossing state without weaving. The metal fiber sheet 6 is a manufacturing method when a non-woven fabric is used, and examples thereof include a method of papermaking by a wet papermaking method. In the wet papermaking method, a slurry made of metal fibers or the like dispersed in an aqueous medium is used, and then wet papermaking is performed using a paper machine. Here, the slurry may also contain additives such as fillers, dispersants, tackifiers, defoamers, paper strength enhancers, sizing agents, flocculants, colorants, and fixing agents. Furthermore, the wet body sheet obtained by the wet papermaking method may be subjected to a fiber entanglement treatment step in which a plurality of metal fibers are entangled with each other. The fiber entanglement treatment step can be exemplified by a method of spraying a high-pressure jet of water toward one main surface of the wet body sheet. According to this method, metal fibers or fibers containing metal fibers can be entangled across the entire wet body sheet. After the wet body sheet undergoes the fiber entanglement treatment step, it then passes through a dryer step using hot air drying. The drying step is preferably implemented in an inert gas environment using a reduced pressure sintering furnace. The sheet after the drier step is cooled to normal temperature and then wound up.

The sheet material obtained through the fiber entanglement treatment step and the dryer step may be subjected to a stamping step before bonding the plurality of metal fibers. According to the stamping step, the excessively large voids existing between the plurality of metal fibers can be reduced, so the homogeneity can be improved. Furthermore, by adjusting the pressure during the punching step, the thickness of the metal fiber sheet 6 can also be adjusted.

In addition, as described above, it is preferable to sinter the bonding portion between the plurality of metal fibers by using the sintering step. According to the sintering step, the bonding between the plurality of metal fibers can be reliably implemented, and the plurality of metal fibers can be fixed, so that the CV value of the basis weight of the metal fiber sheet 6 is stabilized, and the homogeneity and thermal conductivity of the metal fiber sheet 6 are stabilized.

Furthermore, the metal fiber sheet 6 after the sintering step is preferably further subjected to a stamping step. Here, if the punching step is further performed after the sintering step, the homogeneity of the metal fiber sheet 6 can be further improved, and the metal fiber sheet 6 can be thinned. Furthermore, according to the pressing step after the sintering step, the metal fiber moves not only in the thickness direction of the metal fiber sheet 6 but also in the surface direction. Thereby, even if the metal fiber is placed in the void during sintering, the homogeneity of the metal fiber sheet 6 can be improved, and this state can be maintained by the plastic deformability of the metal fiber.

In addition, as the manufacturing method when the metal fiber sheet 6 is a nonwoven fabric, a dry method in which a sheet is subjected to compression molding may also be used. The dry method uses the carding method and the airlaid method to produce a fiber web with metal fibers as the main body, and then compress the fiber web. During compression molding, the bonding agent can also be impregnated in a plurality of metal fibers to bond the plurality of metal fibers. Here, the binder system can be exemplified by organic binders such as acrylic adhesives and inorganic binders such as colloidal silica.

The container 5 is a structure that houses the metal fiber sheet 6. The material of the container 5 can be exemplified by metal and ceramics. Here, examples of metal materials include stainless steel, copper, and aluminum. Furthermore, ceramic materials can be exemplified by alumina, zirconium, barium titanate, silicon carbide, silicon nitride, and aluminum nitride.

The heat exchange plate 7 is a member that includes a temperature adjustment target surface on one main surface, and the metal fiber sheet 6 is adjacent to the back surface of the temperature adjustment target surface, and heat exchange between the temperature adjustment target surface and the metal fiber sheet 6 is performed. The material of the heat exchange plate 7 is preferably a material with higher thermal conductivity, and the material with higher thermal conductivity can be exemplified by stainless steel, copper, and aluminum. Furthermore, if the metal fiber sheet 6 is adjacent to the heat exchange plate 7 through the sintering step, the metal fiber sheet 6 and the heat exchange plate 7 can be bonded, which is preferable. The reason is that if the metal fiber sheet 6 and the heat exchange plate 7 are bonded together, the heat conduction between the metal fiber sheet 6 and the heat exchange plate 7 is easier. The sintering step is best to use a reduced pressure sintering furnace, which is carried out in an inert gas environment.

In addition, between the container 5 and the heat exchange plate 7, a sealing member, which is a member formed by joining these joining materials, is arranged. For such a bonding material, a metal bonding material or an organic bonding material can be used. Examples of metal bonding materials include silver wax, phosphor copper wax, solder, and copper foil. The metal bonding material preferably has a thermal conductivity of 50 W/(m·K) or more and a thickness of 100 μm or less. Examples of organic bonding materials include thermosetting epoxy, urethane, and silicone. Since the thermal conductivity of the organic bonding material is as low as less than 1 W/(m·K), it is preferably thinner from the viewpoint of thermal conductivity, and its thickness is preferably 20 μm or less. The sealing member is preferably, for example, a member in which the metal fiber sheet 6 and the heat exchange plate 7 are bonded together, with the housing body 5 placed thereon, and the heat exchange plate 7 and the housing body 5 are joined by sintering or thermosetting reaction.

In the temperature control unit 1 shown in Fig. 1, if the pressure of the introduced heating medium is increased, the amount of heat transferred by the heating medium is increased to increase the cooling effect or the temperature control effect of the heating effect, but if the heating medium in the housing 5 is increased Pressure, there is a risk of deformation of the temperature control unit. Here, a reinforcing member is provided in the temperature control unit of this embodiment.

In the temperature control unit 1 shown in FIG. 1, the reinforcing member 10 is superposedly arranged on the upper surface of the housing body 5 belonging to one main surface of the temperature control mechanism 3. The material of the reinforcing member 10 can be exemplified by aluminum, copper, alumite, stainless steel, and resin. Here, if the material of the reinforcing member 10 is a material with high thermal conductivity such as aluminum, copper, anticorrosive aluminum, or stainless steel, when the temperature control unit of the present invention is used for cooling purposes, the temperature control unit covered by the reinforcing member 10 The unit 1 as a whole dissipates heat, so it is preferable.

Furthermore, a gap may also be formed between the temperature control unit 1 and the reinforcing member 10, and it is preferable to arrange an organic film. In the temperature control unit 1 shown in FIG. 1, the reinforcement member 10 that is overlapped and arranged on the outer side of the container 5 can mainly suppress the deformation of the upper surface.

However, in the temperature control unit of this embodiment, as shown in FIG. 1, the reinforcement member is not limited to the form which overlaps and arrange|positions on one main surface. Fig. 2 shows a partial cross-sectional view of a first modification of the temperature control unit of this embodiment. In the temperature control unit 1a shown in FIG. 2, the only difference is that it replaces the reinforcing member 10 of the temperature control unit 1 shown in FIG.

In the temperature control unit 1a shown in FIG. 2, the reinforcement member 10a is arrange|positioned so that it may cover at least the side part of the cube-shaped temperature control mechanism 3 which is substantially perpendicular to one main surface. Furthermore, the reinforcing member 10a also covers a part of a main surface of the temperature regulating mechanism 3. The reinforcing member 10a and the reinforcing member 10 differ only in shape. The temperature control unit 1a shown in FIG. 2 has a side surface fixed by a reinforcing member 10a, so that deformation of the entire temperature control unit 1a can be suppressed.

In addition, in the temperature control unit 1a shown in FIG. 2, the thickness of the temperature control unit 1a after the reinforcement member 10a is provided can also be made uniform by reducing the thickness of the temperature control mechanism 3 in the portion covered by the reinforcing member 10a.

However, the temperature control unit of this embodiment is not limited to the form shown in FIGS. 1 and 2. Fig. 3 shows a partial cross-sectional view of a second modification of the temperature control unit of this embodiment. In the temperature control unit 1b shown in FIG. 3, the only difference is that it replaces the reinforcing member 10 of the temperature control unit 1 shown in FIG.

In the temperature control unit 1b shown in FIG. 3, the reinforcing member 10b is arranged so as to cover the entire surface of the temperature control mechanism 3. The reinforcing member 10b and the reinforcing member 10 differ only in shape. The temperature control unit 1b shown in Fig. 3 uses a reinforcing member 10b to suppress the overall deformation.

Furthermore, in the temperature control unit 1b shown in FIG. 3, if the reinforcing member 10b is formed of a material with high thermal conductivity, when the temperature control unit of the present invention is used for cooling purposes, it can be removed from the surface of the temperature control unit 1b. The whole heat dissipation can improve the heat dissipation efficiency. Examples of materials with higher thermal conductivity are metals.

As described above, according to this embodiment, it is possible to obtain a temperature control unit that suppresses deformation due to the pressure of the heating medium in the housing and has a high temperature control effect.

The metal fiber sheet 6c is different from the metal fiber sheet 6 only at the point where the end portion is thinner than the metal fiber sheet 6. The receiving body 5c is different from the receiving body 5 only at the point where the end portion deforms along the shape of the metal fiber sheet 6c.

The reinforcing member 10c is a structure that reinforces the heating unit 1c and can insulate heat. The material system of the reinforcing member 10c can be exemplified by resin. Furthermore, the resin material system can be exemplified as: polyacrylic resin, polyvinylpyrrolidone resin, polyester resin, polypropylene resin, fluororesin such as polytetrafluoroethylene; polyimide resin, polyimide resin, and polymer Phenyl benzobisazole resin.

Fig. 5 shows a partial cross-sectional view of a first modification of the temperature control unit of this embodiment. The difference between the temperature control unit 1d shown in FIG. 5 is that the screw 11 belonging to a rod-shaped member is added to the temperature control unit 1c shown in FIG. 4, and the rest are the same. In addition, examples of rod-shaped members include screws, pins, and welding materials.

The temperature control unit 1d shown in FIG. 5 is inserted into at least a part of the housing 5c, the metal fiber sheet 6c, and the heat exchange plate 7 by screws 11 at the position of the thinner end of the metal fiber sheet 6c. In the temperature control unit 1d shown in FIG. 5, like the temperature control unit 1c shown in FIG. 4, the reinforcing member 10c is used to insulate the rest of the heat exchange plate 7 from the surface where the heat exchange plate 7 is arranged, and suppress deformation, thereby suppressing the housing The peeling between 5c and the metal fiber sheet 6c, and between the metal fiber sheet 6c and the heat exchange plate 7.

However, the temperature control unit of this embodiment is not limited to the form shown in FIGS. 4 and 5. Fig. 6 shows a partial cross-sectional view of a second modification of the temperature control unit of this embodiment. The difference of the temperature control unit 1e shown in FIG. 6 lies in the addition of a nut 12 and the addition of a reinforcing member 10e to the temperature control unit 1d shown in FIG. 5, and the rest are the same. The material system of the reinforcing member 10e can be exemplified by a metal material. Furthermore, the screw 11 and the nut 12 are screw-locked. The temperature control unit 1e shown in FIG. 6 is similar to the temperature control unit 1d shown in FIG.

The difference of the temperature adjustment unit 1f shown in FIG. 7 is that the reinforcing member 13 is provided to the temperature adjustment mechanism 3 of the temperature adjustment unit 1 shown in FIG. 1, and the rest are the same. The reinforcing member 13 is inserted into the temperature control mechanism 3, for example. The reinforcing member 13 is a plate-shaped or rod-shaped member that functions as a column or a beam in the temperature control unit 1f. The material of the reinforcing member 13 can be exemplified by a metal material. In the temperature control unit 1f shown in FIG. 7, the reinforcement member 13 is used to suppress deformation caused by the pressure of the heating medium in the housing, and to improve the mechanical strength inside the temperature control unit 1f.

Fig. 8 shows a partial cross-sectional view of a modified example of the temperature control unit of this embodiment. The difference between the temperature control unit 1g shown in FIG. 8 is that the reinforcing member 14 is provided to the temperature control mechanism 3 of the temperature control unit 1 shown in FIG. 1, and the rest are the same. The reinforcing member 14 is inserted into the temperature control mechanism 3, for example.

The reinforcing member 14 is a member that functions as a column or a beam in the temperature control unit 1g. The reinforcing member 14 is different from the reinforcing member 13 and also extends to the outside of the receiving body 5, which can improve the mechanical strength of the surface on which the receiving body 5 is arranged.
