Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the description of the following embodiments. In addition, in the following description, the same component numbers are attached to the same components.

First, define the terms used in the following instructions. The so-called "metal fibers" refer to fibers with metal as the main component. For example, "copper fibers" refer to fibers with copper as the main component. Furthermore, when a metal is used as the main component, unavoidable impurities are contained, and components other than the metal may be contained in a certain amount as long as the effect of the present invention is not hindered. In addition, "thermal conductivity (W/(m·K))" is a value measured using the laser flash method (for example, laser flash thermal constant measuring device "TC7000 type" manufactured by ULVAC-RIKO Co., Ltd.). Furthermore, the so-called "average fiber diameter" refers to the cross-sectional area perpendicular to the long side direction of the metal fiber calculated based on the plurality of vertical cross-sections of the metal fiber sheet photographed by the microscope. By calculating the cross-sectional area with the same area The diameter of a perfect circle is 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 measuring the length values in the long side direction of a plurality of randomly selected fibers in a microscope image, and then calculating the arithmetic mean of these values. In addition, when the fiber is not linear, the length of the curve along the fiber is used. Here, the plural number of branches can be set to 20 branches, for example. Furthermore, the so-called "volume ratio" refers to the proportion of the fiber part in the volume of the fiber sheet. It is calculated from the basis weight and thickness of the fiber sheet and the true density of the fiber by the following formula. Here, when the fiber sheet contains multiple types of fibers, the volumetric ratio can be calculated by using the true density value that reflects the composition ratio of each fiber. (Occupancy rate (%)) = (basis weight of fiber sheet)/((fiber sheet thickness) × (real density)) × 100. Here, the so-called "sheet thickness" refers to the arithmetic mean when measuring the measurement points of a metal fiber sheet using a terminal drop-type film thickness meter using air (for example, "Digital Gauge ID-C112X" manufactured by Mitutoyo Co., Ltd.). 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. As an index of homogeneity, for example, the coefficient of variation (CV (Coefficient of Variation) value) of the basis weight specified by JIS Z8101 per 1 cm ² can be used. The so-called "void ratio" refers to the proportion of voids relative to the volume of the fiber sheet. It 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, the volumetric ratio can be calculated by using the true density value that reflects the composition ratio of each fiber. (Void ratio (%)) = (1-(basis weight of fiber sheet)/((fiber sheet thickness) × (real density))) × 100. The heating medium used in the temperature control unit of the present invention can be gas, liquid, etc., and the relevant 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 compound such as hydrofluorocarbon or hydrofluoroether.

<Embodiment 1> FIG. 1 is a partial cross-sectional view of the temperature control unit 1 of this embodiment. The temperature control unit 1 shown in FIG. 1 is equipped with a temperature control mechanism 3 through which a heating medium passes, and a heating medium inlet 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, it is preferable to provide a static mixer in the heating medium inlet in order to generate turbulent flow and diffuse the introduced heating medium. In addition, examples of the heating medium include water, air, and fluorine-based solvents.

The temperature control mechanism 3 is provided with: a metal fiber sheet 6 containing metal fibers, a storage body 5 that accommodates the metal fiber sheet 6 and is closed by a heat exchange plate 7, and a heat exchange plate 7; the heat exchange plate 7 is a main body. The main surface is exposed to the outside, and the back surface of the main surface is in contact with the metal fiber sheet 6, so that heat exchange between the metal fiber sheet 6 and the outside is performed.

The metal fiber sheet 6 may be composed of metal fibers alone or may contain components other than metal fibers. Examples of the metal component of the metal fiber include 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 rigidity and plastic deformation of copper fibers. In addition, examples of precious metals include gold, platinum, silver, palladium, rhodium, iridium, ruthenium and osmium. In addition, the components other than metal fibers contained in the metal fiber sheet 6 may be, for example, polyethylene terephthalate (PET: Poly-Ethylene Terephthalate), polyvinyl alcohol (PVA: Poly-Vinyl Alcohol), Polyolefin, polyvinyl chloride (PVC: Poly-Vinyl Chloride), polyamide, acrylic, and organic substances that impart adhesiveness and support to fibrous materials. Especially when the metal fiber sheet 6 is a non-woven fabric made of a plurality of metal fibers randomly interlaced, by containing any one or a plurality of these organic substances, the shape maintenance and functionality of the metal fiber sheet 6 can be assisted or improved during production. .

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 to physically fix the plurality of metal fibers and form a bonding portion between the plurality of metal fibers. The metal fiber sheet 6 can have a plurality of metal fibers directly fixed using an adhesive portion, or can be fixed indirectly. It is preferable that at least a part of the metal fibers constituting the metal fiber sheet 6 form a gap. The reason for this is that if such a gap is formed in the metal fiber sheet 6 , the heating medium described later can be introduced into the metal fiber sheet 6 more easily. Furthermore, it is preferable if the plurality of metal fibers are sintered in the bonded portion because the thermal conductivity and homogeneity of the metal fiber sheet 6 will be stable. The gaps formed between the plurality of metal fibers can also be formed by the intersection of metal fibers. In addition, the porosity of the metal fiber sheet 6 is preferably 5% or more and 99% or less, and 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, on the premise that the metal fiber sheet 6 is a sheet-like structure, it may be a non-woven fabric composed of a plurality of metal fibers that are randomly intertwined, or it may be a regular woven fabric or mesh material. Furthermore, the surface of the metal fiber sheet 6 may be flat or may have a corrugated surface.

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 10g/m2 ^or more, the cooling or heating effect can be improved; if the basis weight of the metal fiber sheet 6 is set to less than 1000g/ ^m2 , the weight of the metal fiber sheet 6 can be reduced. .

However, if the average fiber diameter of the metal fibers of the metal fiber sheet 6 is less than 1 μm, the rigidity of the metal fibers will be reduced, and agglomeration will easily occur when manufacturing the metal fiber sheet 6, resulting in a loss of thermal conductivity and homogeneity of the metal fiber sheet 6. for instability. 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 will be too high, making it difficult to intertwine. 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, and more preferably 2 μm or more and 20 μm or less. Furthermore, when the metal fiber sheet 6 is a non-woven fabric composed of a plurality of metal fibers that 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 fibers of the metal fiber sheet 6 is preferably 1 mm. Above and below 10mm.

Furthermore, if the aspect ratio of the metal fibers in the metal fiber sheet 6 is less than 33, it is difficult for the metal fibers to intertwine. On the other hand, if the aspect ratio of the metal fibers of the metal fiber sheet 6 exceeds 10,000, the homogeneity of the metal fiber sheet 6 decreases. Therefore, the aspect ratio of the metal fiber is preferably 33 or more and 10,000 or less.

Furthermore, if the volume ratio of the metal fiber sheets 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 area ratio of the metal fiber sheets 6 exceeds 65%, the pressure loss when the heating medium is introduced increases. Therefore, the area ratio of the metal fiber sheets 6 is preferably more than 2%, more preferably more than 4%, and more preferably more than 5%; preferably less than 65%, more preferably less than 60%.

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 specified by JIS Z8101 per 1 cm ² of the metal fiber sheet 6 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 fabric, can use a plain weaving with metal wires crossing each other, or can also use a metal wire arranged longitudinally and a metal wire arranged transversely, each with 2 metal wires at a time. The upper branches are woven in a crossing manner. Alternatively, overlay, flat or damask weaving can be used. Alternatively, when the metal fiber sheet 6 is a mesh material, the metal wires can also be welded in a warp-crossing state without braiding. When the metal fiber sheet 6 is a nonwoven fabric, the manufacturing method may be, for example, papermaking using a wet papermaking method. In the wet papermaking method, a slurry made of metal fibers dispersed in an aqueous medium is used, and a paper machine is used to wet papermaking. Here, the slurry may also contain additives such as fillers, dispersants, tackifiers, defoaming agents, paper strength enhancers, sizing agents, coagulants, colorants, and fixing agents. Furthermore, the wet sheet obtained by the wet sheet-making method may also be subjected to a fiber entanglement process in which a plurality of metal fibers are entangled with each other. The fiber entanglement treatment step may be, for example, a method of spraying high-pressure jet water towards 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 sheet undergoes a fiber entanglement treatment step, it then goes through a dryer step using hot air drying. This drying step is preferably carried out in an inert gas environment using a reduced pressure sintering furnace. After the dryer step, the sheet is cooled to normal temperature and then rolled up.

The sheet obtained through the fiber interlacing treatment step and the dryer step may also undergo a stamping step before bonding the plurality of metal fibers. According to the stamping step, excessive gaps existing between the plurality of metal fibers can be reduced, so the homogeneity can be improved. Furthermore, by adjusting the pressure during the stamping step, the thickness of the metal fiber sheet 6 can also be adjusted.

In addition, as mentioned above, it is preferable that the bonded portions between the plurality of metal fibers are sintered by a 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 can be stabilized, and the homogeneity and thermal conductivity of the metal fiber sheet 6 can be stabilized.

Furthermore, the metal fiber sheet 6 after the sintering step is preferably further subjected to a stamping step. Here, if a stamping 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 made thinner. Furthermore, according to the stamping step after the sintering step, the metal fibers move not only in the thickness direction of the metal fiber sheet 6 but also in the surface direction. In this way, metal fibers are arranged even in places where there are gaps during sintering, which can improve the homogeneity of the metal fiber sheet 6 and maintain this state by utilizing the plastic deformation of the metal fibers.

In addition, when the metal fiber sheet 6 is a nonwoven fabric, the dry method of compressing the sheet may also be used. The dry method uses carding method, air-laying method, etc. to produce a fiber mesh with metal fibers as the main body, and then compresses the fiber mesh. During compression molding, the binder can also be impregnated into a plurality of metal fibers to bond the plurality of metal fibers. Here, examples of the binder include organic binders such as acrylic adhesives and inorganic binders such as colloidal silica.

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

The heat exchange plate 7 has a temperature adjustment target surface on one main surface and is adjacent to the metal fiber sheet 6 on the back side of the temperature adjustment target surface to perform heat exchange between the temperature adjustment target surface and the metal fiber sheet 6 . The heat exchange plate 7 is preferably made of a material with high thermal conductivity, and examples of materials with high thermal conductivity include stainless steel, copper, and aluminum. Furthermore, it is preferable if the sintering step is carried out in a state where the metal fiber sheet 6 is adjacent to the heat exchange plate 7, so that the metal fiber sheet 6 and the heat exchange plate 7 can be bonded. The reason is that if the metal fiber sheet 6 and the heat exchange plate 7 are bonded, the heat conduction between the metal fiber sheet 6 and the heat exchange plate 7 will be easier. The sintering step is preferably performed in a reduced pressure sintering furnace under an inert gas environment.

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

As shown in Figure 1 , if the pressure of the heating medium introduced into the temperature regulating unit 1 is increased, the heat transferred by the heating medium increases, thereby improving the cooling effect or the temperature regulating effect of the heating effect. However, if the heating medium in the container 5 is increased If the pressure is too high, there is a risk of deformation of the temperature control unit. Here, the temperature control unit of this embodiment is provided with a reinforcing member.

In the temperature control unit 1 shown in FIG. 1 , the reinforcing member 10 is overlapped and arranged on the receiving body 5 which is a main surface of the temperature control mechanism 3 . Examples of the material of the reinforcing member 10 include aluminum, copper, anti-corrosion aluminum, stainless steel and resin. Here, if the material of the reinforcing member 10 is a material with high thermal conductivity such as aluminum, copper, anti-corrosion aluminum or stainless steel, then when the temperature control unit of the present invention is used for cooling purposes, the temperature control unit covered by the reinforcing member 10 Unit 1 dissipates heat as a whole, so it is preferable.

Furthermore, a gap may be formed between the temperature control unit 1 and the reinforcing member 10, and an organic film is preferably disposed. In the temperature control unit 1 shown in FIG. 1 , the reinforcing member 10 overlapped on the outside of the housing 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 reinforcing members are not limited to the form in which they are overlapped and arranged on one main surface. FIG. 2 is a partially cross-sectional view showing a first modification example of the temperature control unit of this embodiment. In the temperature control unit 1a shown in Figure 2, the only difference is that the reinforcing member 10 of the temperature control unit 1 shown in Figure 1 is replaced with a reinforcing member 10a, and the other parts are the same.

In the temperature control unit 1a shown in FIG. 2, the reinforcing member 10a is arranged to cover at least the side portion of the cube-shaped temperature control mechanism 3 that is substantially perpendicular to a main surface. Furthermore, the reinforcing member 10a also covers part of a main surface of the temperature regulating mechanism 3. The reinforcing member 10a and the reinforcing member 10 are different only in shape. The temperature control unit 1a shown in FIG. 2 is fixed on the side by a reinforcing member 10a, which can suppress the deformation of the entire temperature control unit 1a.

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

However, the temperature control unit of this embodiment is not limited to the form shown in FIGS. 1 and 2 . FIG. 3 is a partially cross-sectional view of a second modification example of the temperature control unit of this embodiment. In the temperature control unit 1b shown in Figure 3, the only difference is that the reinforcing member 10 of the temperature control unit 1 shown in Figure 1 is replaced with a reinforcing member 10b, and the other parts are the same.

In the temperature control unit 1b shown in FIG. 3, the reinforcing member 10b is disposed so as to cover the entire surface of the temperature control mechanism 3. The reinforcing member 10b is different from the reinforcing member 10 only in shape. The temperature control unit 1b shown in FIG. 3 uses the 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 made 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 entire unit dissipates heat to improve heat dissipation efficiency. Examples of materials with higher thermal conductivity include metals.

The difference between the temperature control unit 1e shown in Fig. 6 is that the nut 12 and the reinforcing member 10e are added to the temperature control unit 1d shown in Fig. 5, and the other parts are the same. The material of the reinforcing member 10e may be, for example, a metal material. Furthermore, the screw 11 and the nut 12 are screw-locked. In the temperature control unit 1e shown in FIG. 6, like the temperature control unit 1d shown in FIG. 5, the reinforcing member 10e is used to insulate the remaining surfaces other than the surface where the heat exchange plate 7 is arranged, and to suppress deformation, thereby more reliably suppressing the storage.
