This application is based on Japanese Patent Application No. 2016-245478 filed on December 19, 2016 and Japanese Patent Application No. 2017-186657 filed on September 27, 2017. The description is incorporated.

This disclosure relates to a heat conduction device that conducts heat from a heat source.

Conventionally, heat conduction devices that use metal piping or Peltier elements through which a temperature-controlled heat medium flows as a heat source (heat source or cold source) and take heat away from the human body by heat conduction or give heat to the human body are known. It has been.

In such a heat conduction device, when a contact surface with a human body or clothes is directly formed on the surface of the heat source, the device tends to be large or rigid. For this reason, there is a case where a temperature control surface that comes into contact with the human body is formed by a heat conduction (heat transfer) member connected to the heat source, but the heat source increases due to the increase in heat resistance with the distance from the heat source and the heat entering and exiting from the middle. It is difficult to adjust the temperature of the portion far from the portion closer to the center, and it may be difficult to adjust the temperature uniformly over the entire temperature control surface.

Therefore, for the purpose of uniform temperature adjustment over the entire temperature control surface, in Patent Document 1, a pipe through which a heat medium circulates is arranged along the periphery of the contact surface, and a plurality of heat conduction members are connected to the pipe. A device has been proposed. Furthermore, in the heat conduction device of Patent Document 1, a metal plate such as an aluminum plate is inserted between the temperature control surface of the human body and the heat conduction material as a soaking plate in order to more uniformly adjust the temperature of the entire temperature control surface. is doing.

JP 2013-19645 A

According to the study of the inventors of the present disclosure, in the heat conduction device of Patent Document 1, in the length direction of each heat conduction material, the thermal resistance may increase with an increase in the distance from the heat source. In addition, the heat flowing into the heat conducting material in the portion close to the heat source may affect the heat transport with the portion far from the heat source. Therefore, a temperature gradient is generated between the end near the heat source of the heat conducting material and the other end, and there is a possibility that uniform temperature adjustment over the entire temperature control surface cannot be performed sufficiently. In addition, even if a metal plate is installed as a soaking plate between the contact surface and the heat conducting material, a certain thickness or more is necessary to fully develop the soaking property on the contact surface, and the heat from the heat source is reduced. In some cases, heat transfer to the human body is insufficient.

In view of the above points, an object of the present disclosure is to provide a heat conduction device that enables uniform temperature adjustment in the entire temperature control surface.

The heat conduction device according to an aspect of the present disclosure includes a heat source unit, a temperature control surface, and a heat conduction unit. The heat source unit generates at least one of hot and cold. The temperature control surface is partitioned into a plurality of temperature control units, and at least a part of the plurality of temperature control units is arranged away from the heat source unit. A plurality of heat conduction parts connect between a heat source part and a plurality of temperature control parts so that heat conduction is possible.

This makes it possible to directly heat or cool the temperature control section divided into a plurality by the heat of the heat source section. For this reason, even in the temperature control unit arranged far from the heat source unit, it can be heated or cooled in the same manner as the temperature control unit arranged near the heat source unit, and the entire temperature control surface is adjusted to a uniform temperature. can do.

Not only combinations of parts that clearly show that combinations are possible in each embodiment, but also combinations of the embodiments even if they are not explicitly stated unless there is a problem with the combination. Is also possible.

(First embodiment)
Hereinafter, a first embodiment of the present disclosure will be described with reference to the drawings. The heat conduction device 1 of the present embodiment is a panel-shaped air conditioning device, and can be applied to, for example, a vehicle temperature control sheet.

As shown in FIG. 1, the heat conduction device 1 of the present embodiment includes a heat source unit 10. The heat source unit 10 functions as at least one of a hot heat source for supplying hot heat and a cold heat source for supplying cold heat.

The heat source unit 10 of the present embodiment is configured as a cooling water passage through which the temperature-controlled cooling water flows. In the example shown in FIG. 1, the cooling water flows through the inside of the heat source unit 10 in the depth direction of the drawing sheet.

Cooling water is a heat medium that receives the heat of a heating device (not shown) or the cooling heat of a cooling device (not shown). The heat generating device is a device that generates heat during operation, and examples thereof include an internal combustion engine, a water-cooled intercooler, and an inverter. The cooling device is a device that generates cold during operation, and examples thereof include a chiller of a refrigeration cycle.

The heat conduction device 1 includes a temperature control surface 11. The temperature control surface 11 is arranged so that at least a part thereof is separated from the heat source unit 10. The temperature control surface 11 constitutes a contact surface that comes into contact with the human body.

The temperature control surface 11 is partitioned into a plurality of temperature control units 11 a, and the heat source unit 10 and the individual temperature control units 11 a are thermally connected by the heat conductive sheet 12 via the heat resistance adjustment unit 14. . The other end side of the heat conductive sheet 12 is connected to the temperature control part 11a mentioned above. In addition, the heat conductive sheet 12 respond | corresponds to the heat conductive part of this indication. Since each temperature control unit 11a is connected to the heat source unit 10, the heat of the heat source unit 10 can be directly conducted in any temperature control unit 11a, so that uniform temperature adjustment is possible. The plurality of temperature control units 11a are partitioned according to the distance from the heat source unit 10, thereby enabling more uniform temperature adjustment. Here, uniform temperature adjustment is to adjust to a temperature at which warmth or coldness can be sensed without feeling uncomfortable or uncomfortable when the human body comes into contact. By the uniform temperature adjustment, the temperature distribution on the temperature control surface 11 is set so that the difference between the high compartment temperature and the low compartment temperature is within 20 ° C., more desirably within 10 ° C., and even within 5 ° C. Can feel comfortable without feeling uncomfortable.

In this embodiment, the heat conductive sheet 12 and the temperature control part 11a are integrated, and a part of the heat conductive sheet 12 constitutes the temperature control part 11a. For this reason, although the heat conductive sheet 12 and the temperature control part 11a are comprised from the same material, the material which comprises the heat conductive sheet 12 and the temperature control part 11a does not necessarily need to be the same. In addition, when exchanging the heat of the temperature control surface 11 with the human body, if a sufficient amount of heat or a thermal sensation felt by the human body can be ensured, the human body touches the temperature control surface 11 by covering it with a cloth or the like. Comfort can be improved. Moreover, you may coat | cover the surface of the temperature control surface 11 with the sheet | seat member for protection.

The plurality of temperature control units 11a are partitioned according to the distance from the heat source unit 10, thereby enabling more uniform temperature adjustment. In the example illustrated in FIG. 1, the plurality of temperature control units 11 a are partitioned into five along directions in which the distance from the heat source unit 10 is different (that is, the left-right direction in FIG. 1). The heat conductive sheet 12 is provided corresponding to a plurality of temperature control units 11 a divided according to the distance from the heat source unit 10. As the distance from the heat source unit 10 increases, the length of the heat conductive sheet 12 increases, the thermal resistance due to the heat conductive sheet 12 increases, and heat is less likely to be transmitted to the temperature control unit 11a. By dividing the plurality of temperature control units 11a according to the distance from the heat source unit 10, to the near temperature control unit 11a where heat is easily transmitted from the heat source unit 10, and to the far temperature control unit 11a where heat is not easily transmitted from the heat source unit 10 Therefore, the temperature can be adjusted uniformly over the entire temperature control surface 11. In addition, in the example shown in FIG. 1, the temperature control part 11a divided along the direction from which the distance from the heat source part 10 differs further in the direction orthogonal to the direction from which the distance from the heat source part 10 differs (that is, in FIG. Although it is divided into three along the (depth direction), the plurality of temperature control parts 11a are not necessarily divided in the direction orthogonal to the direction in which the distance from the heat source part 10 is different.

The plurality of heat conductive sheets 12 have different lengths depending on the distance between the temperature control unit 11a and the heat source unit 10. In the example shown in FIG. 1, the heat conductive sheet 12 provided above is short, and the heat conductive sheet 12 provided below is long. Therefore, when the same material, width, and thickness are used as the heat conductive sheet 12 for each temperature control unit 11a, the thermal resistance up to the heat source unit 10 is derived from the difference in the length of the heat conductive sheet 12. A difference arises between the temperature control parts 11a. By adjusting the difference in thermal resistance caused by the heat conductive sheet 12 and making the thermal resistance up to the heat source unit 10 the same, more uniform temperature control is possible on the entire temperature control surface 11.

In this embodiment, a thermal resistance adjusting unit 14 is provided between the heat source unit 10 and the thermal conductive sheet 12 in order to adjust the thermal resistance derived from the difference in length of the thermal conductive sheet 12. The thermal resistance adjusting unit 14 has a function of adjusting the thermal resistance between the heat source unit 10 and the plurality of temperature adjusting units 11a.

The thermal resistance adjusting unit 14 is a heat source between the heat source unit 10 and the temperature control unit 11a according to the distance between the heat source unit 10 and the temperature control unit 11a. The resistance is adjusted. The longer the heat conductive sheet 12, the greater the heat resistance based on the heat conductive sheet 12, and the shorter the heat conductive sheet 12, the smaller the heat resistance based on the heat conductive sheet 12. For this reason, the heat resistance adjusting unit 14 prevents the heat source unit 10 and the short heat conductive sheet 12 from increasing while preventing the heat resistance between the heat source unit 10 and the temperature control unit 11a to which the long heat conductive sheet 12 is connected as much as possible. It adjusts so that the thermal resistance between the temperature control part 11a to connect becomes large. Specifically, the thermal resistance between the heat source unit 10 and each heat conductive sheet 12 can be adjusted by changing the length of the thermal resistance adjusting unit 14 between the heat source unit 10 and the heat conductive sheet 12. ing. Here, the longer the heat conductive sheet 12, the shorter the length in the left-right direction between the heat conductive sheet 12 and the heat source unit 10 in the heat resistance adjusting unit 14, and the shorter the heat conductive sheet 12, the heat resistance adjusting unit 14 is. The length in the left-right direction between the heat conductive sheet 12 and the heat source unit 10 is increased.

Thereby, the thermal resistance between the heat source unit 10 and each temperature control unit 11a can be made uniform, and the temperature distribution generated on the temperature control surface 11 can be reduced.

Moreover, in this embodiment, although the thermal resistance adjustment part 14 is installed between the heat-source part 10 and the heat conductive sheet 12, the temperature control part 11a which is a contact part with the intermediate part of a heat conductive sheet 12, or a human body. It is also possible to install in.

The heat resistance adjusting unit 14 can accurately adjust the thermal resistance between the heat source unit 10 and the temperature adjusting unit 11a by being configured with a low heat resistance member. When adjusting the thermal resistance with a high thermal resistance member, the thermal resistance tends to increase even if the thermal resistance is arranged with a small size, and processing with very high dimensional accuracy is required. On the other hand, when a low thermal resistance member is used, it can be arranged with a large size when correcting the same amount of thermal resistance, and the required processing accuracy can be suppressed. Examples of the low thermal resistance member include high thermal conductivity materials such as graphite or various metal materials such as aluminum, copper, silver, gold, and titanium. Moreover, it is also possible to improve corrosion resistance by using titanium. On the other hand, even if it is a low thermal conductivity material such as a resin, it is also possible to use a film or tape whose thickness and other dimensions are controlled with high accuracy as the low thermal resistance member. In this case, it is possible to give the thermal resistance adjusting portion 14 a function as a joining member by using an adhesive or sticky one.

As a method of adjusting the thermal resistance between the heat source unit 10 and each temperature control unit 11a, not only the above-described method of installing the thermal resistance adjustment unit 14, but also adjusting the thickness, shape, and thermal conductivity of the thermal conductive sheet. This is possible. Specifically, in order to adjust the thermal resistance between the heat conductive sheet 12 and the heat source unit 10 connecting the temperature control unit 11a close to the heat source unit 10, a material having a low thermal conductivity of the heat conductive sheet is used. It is possible to adjust the thermal resistance by reducing the thickness of the heat conductive sheet, narrowing the width, or giving a two-dimensional or three-dimensional shape.

Since the heat conductive sheet 12 is laminated, it can be formed into a compact shape and can be installed in a narrow place.

The heat conductive sheet 12 is made of a sheet-like high heat conductive material. As the high thermal conductivity material, a carbon material or a metal material can be used. As the carbon material, a sheet using carbon fiber, carbon nanotube, graphene, diamond or the like can be used in addition to the graphite sheet. As the metal, it is possible to use simple metals such as gold, silver, aluminum, copper, and alloys of these metals.

Furthermore, the heat conductive sheet 12 is more anisotropic heat that easily conducts heat in a direction parallel to the sheet surface (left and right direction and depth direction in the figure) than in a direction orthogonal to the sheet surface (up and down direction in the figure). By using a conductive material, it is possible to reduce the influence from the vertical direction and to conduct heat conduction between the temperature control surface 11a and the heat source 10 more favorably. As the degree of anisotropy of the thermal conductivity, the thermal conductivity in the direction parallel to the sheet surface is 10 times or more, more preferably 100 times or more, compared with the thermal conductivity in the direction perpendicular to the sheet surface. In addition, the heat conductivity of the heat conductive sheet 12 in the direction parallel to the sheet surface, that is, the direction connecting the heat source unit 10 and the temperature control unit 11a is higher than the heat conductivity in at least one other direction. Just do it.

Examples of such a high thermal conductive material include graphite sheets such as GRAPHINITY (manufactured by Kaneka), PGS graphite sheet (manufactured by Panasonic), and GD-AGS (manufactured by Guardneck). In the present embodiment, Kaneka's graphicity (thickness: 40 μm) is used as the high thermal conductivity material. Kaneka's GRAPHINITY used in this embodiment has a thermal conductivity of 1500 W / mK in a direction parallel to the sheet surface and a thermal conductivity of 5 W / mK in a direction perpendicular to the sheet surface. The thermal conductivity is 300 times the thermal conductivity in the orthogonal direction.

A single graphite sheet may be used as one heat conductive sheet 12, or a plurality of graphite sheets may be stacked and used as one heat conductive sheet 12. When a plurality of graphite sheets are overlapped and used as one heat conductive sheet 12, the heat conductivity of the heat conductive sheet 12 can be improved.

The plurality of heat conductive sheets 12 are laminated. Between the heat conductive sheets 12 adjacent to each other, the heat insulating sheets 13 are arranged and laminated alternately. The heat insulating sheet 13 covers the heat conductive sheet 12. The heat insulating sheet 13 is a sheet-like heat insulating material, and for example, a foamed resin such as foamed urethane, foamed olefin, and foamed acrylic, or ceramic fibers such as glass wool or silica wool can be used. In this embodiment, as the heat insulating sheet 13, a marine tex cloth (thickness: 0.18 mm) manufactured by NICHIAS or LZ-2000 (thickness: 0.9 mm) manufactured by INOAC is used. The heat insulating sheet 13 corresponds to the heat insulating portion of the present disclosure.

The heat insulating sheet 13 makes it difficult for heat to be transmitted between the heat conductive sheets 12. For this reason, not only the effect of being able to directly conduct the heat or cold of the heat source unit 10 to the temperature control unit 11a by the heat conductive sheet 12 as described above, but also the temperature of an object (for example, a human body) in contact with each temperature. Even in the case where the adjustment section 11a is different, it is difficult to be influenced by the temperature change of the other temperature adjustment section 11a, and a desired temperature adjustment is possible.

As shown in FIGS. 1 and 2, the heat conductive sheet 12 and the heat insulating sheet 13 are bent at one or a plurality of locations corresponding to these thicknesses. Thereby, in this embodiment, the some temperature control part 11a is located on the same plane.

By using a flexible material as a constituent material of the heat conductive sheet 12 and the heat insulating sheet 13, it can be bent or twisted and a curved surface can be formed. As a material of the flexible heat conductive sheet 12, in addition to a carbon material such as a graphite sheet, a metal plate can be used in a thin state. Moreover, as a material of the flexible heat insulating sheet 13, the above-described foamed resin, glass wool, ceramic fibers such as silica wool, or the like can be used.

The heat source unit 10 and the thermal resistance adjusting unit 14 are accommodated in a housing 15. The periphery of the housing 15 is covered with a heat source heat insulating portion 16. The housing 15 can be made of the same material as that of the thermal resistance adjusting unit 14, for example. When the casing 15 and the thermal resistance adjusting unit 14 are made of the same material, the casing 15 and the thermal resistance adjusting unit 14 may be integrally formed.

The same material as the heat insulating sheet 13 can be used for the heat source heat insulating portion 16. The heat source heat insulation part 16 can suppress the release of heat to the outside from the heat source part 10 and the thermal resistance adjustment part 14, and can increase the amount of heat that can be transported from the heat source part 10 to the temperature adjustment part 11a. This heat source heat insulation part 16 is not necessarily required when the heat of the heat source part 10 can be sufficiently transported to the temperature control part 11.

When the plurality of heat conductive sheets 12 and the plurality of heat insulating sheets 13 are laminated, the sheets 12 and 13 can be bonded to each other with an adhesive or the like. In this case, the sheets 12 and 13 may be bonded over the entire surface, or the sheets 12 and 13 may be bonded in part.

When the sheets 12 and 13 are bonded together in part, for example, the portions of the sheets 12 and 13 accommodated inside the casing 15 are bonded, and the sheets 12 and 13 exist outside the casing 15. What is necessary is just not to adhere | attach a part. When the sheets 12 and 13 are partially bonded, the laminated body composed of the plurality of heat conductive sheets 12 and the plurality of heat insulating sheets 13 is more flexible than the case where the sheets 12 and 13 are bonded over the entire surface. Can be given.

FIG. 2 shows the flow of heat when cooling is supplied from the heat source unit 10 and cooling is performed when the human body contacts the temperature control surface 11. In the example shown in FIG. 2, an example in which the temperature adjustment surface 11 is divided into three temperature adjustment portions 11 a according to the distance from the heat source portion 10 is shown. As shown in FIG. 2, the heat of the human body moves from the temperature adjustment unit 11 a to the heat source unit 10 through the heat conductive sheet 12. Thereby, the human body which contacts the temperature control part 11a is cooled by the cold heat of the heat source part 10.

　図３および表１は、温調面１１の表面温度と、温調面１１の熱源部１０からの距離との関係を示している。図３および表１に示す例は、熱源部１０の温度を５℃、外気温を２６℃としている。図３および表１では、温調面１１が複数に分割されていない構成を比較例として示している。図３、４では、２６℃を点線で示している。

FIG. 3 and Table 1 show the relationship between the surface temperature of the temperature control surface 11 and the distance from the heat source unit 10 of the temperature control surface 11. In the example shown in FIG. 3 and Table 1, the temperature of the heat source unit 10 is 5 ° C., and the outside air temperature is 26 ° C. In FIG. 3 and Table 1, the structure which the temperature control surface 11 is not divided | segmented into plurality is shown as a comparative example. 3 and 4, 26 ° C. is indicated by a dotted line.

As shown in FIG. 3 and Table 1, in the comparative example in which the temperature control surface 11 is configured integrally, the degree of increase in the surface temperature of the temperature control surface 11 is high, and the temperature is rapidly changed from a portion close to the heat source unit 11 to the outside air temperature. It is approaching. On the other hand, in the present embodiment in which the temperature control surface 11 is divided into a plurality of temperature control portions 11a, the surface temperature of the temperature control surface 11 gradually increases. For this reason, in this embodiment, the state where the surface temperature of the temperature control surface 11 is low is maintained even at a part away from the heat source unit 11 to some extent. That is, in the present embodiment, it is possible to effectively transport the cold heat of the heat source unit 10 to a place away from the heat source unit 10.

　図４および表２は、温調面１１の途中で人体が接触した場合において、温調面１１の表面温度と、温調面１１の熱源部１０からの距離との関係を示している。図４および表２に示す例では、熱源部１０から３ｃｍ離れた位置で人体が温調面１１に接触しているものとする。図４および表２に示す例においても、熱源部１０の温度を５℃、外気温を２６℃とし、温調面１１が複数に分割されていない構成を比較例として示している。

4 and Table 2 show the relationship between the surface temperature of the temperature control surface 11 and the distance of the temperature control surface 11 from the heat source unit 10 when a human body comes in contact with the temperature control surface 11. In the example shown in FIG. 4 and Table 2, it is assumed that the human body is in contact with the temperature control surface 11 at a position 3 cm away from the heat source unit 10. Also in the examples shown in FIG. 4 and Table 2, a configuration in which the temperature of the heat source unit 10 is 5 ° C., the outside air temperature is 26 ° C., and the temperature control surface 11 is not divided into a plurality is shown as a comparative example.

As shown in FIG. 4 and Table 2, in the comparative example in which the temperature control surface 11 is integrally configured, the surface temperature of the temperature control surface 11 rapidly increases at a portion farther from the heat source unit 10 than the contact portion of the human body. is doing. That is, in the comparative example, although the cold heat of the heat source unit 10 can be transmitted to the human body that is in contact with the temperature control surface 11, the influence of the heat of the human body is exerted at a part farther than the part touched by the human body from the heat source part 10. The cold heat of the heat source unit 10 is difficult to be transported. Therefore, when a human body having a certain area or more is in contact with the temperature control surface 11 at the same time, the human body part that is in contact with the temperature control surface 11 near the heat source can feel the heat or cold, but the heat in the heat control surface 11 can be felt. The human body part that is in contact with the temperature control surface 11 away from the heat source may not be able to fully feel the heat or the cold due to going in and out.

On the other hand, in this embodiment, since the several temperature control part 11a and the heat-source part 10 which comprise the temperature control surface 11 are each independently connected by the heat conductive sheet 12, some temperature control surfaces 11 are included. Even when the human body comes into contact with other parts, the other portions of the temperature control surface 11 are not easily affected. For this reason, in this embodiment, the state where the surface temperature of the temperature control surface 11 is low is maintained also in the part far from the heat source part 10 rather than the contact part of a human body. That is, in the present embodiment, cold heat can be transmitted to the human body that is in contact with the temperature control surface 11, and the cold heat of the heat source unit 10 is also effective in a place farther than the part touched by the human body from the heat source unit 10. Be transported to. As a result, it is possible to uniformly adjust the temperature of the temperature control surface 11 without being affected by disturbance factors generated in the middle of the temperature control surface 11.

According to the present embodiment described above, the temperature adjustment surface 11 is divided into a plurality of temperature adjustment portions 11 a according to the distance from the heat source portion 10, and each temperature adjustment portion 11 a and the heat source portion 10 are separated by the heat conductive sheet 12. Connected. Thereby, irrespective of the distance from the heat source part 10, the temperature control part 11a can be directly heated or cooled by the heat of the heat source part 10. For this reason, also in the temperature control part 11a arrange | positioned far from the heat source part 10, it can be heated or cooled similarly to the temperature control part 11a arrange | positioned near the heat source part 10, and the whole temperature control surface 11 is made. It can be adjusted to a uniform temperature.

Further, according to the configuration of the present embodiment, for example, when a human body comes into contact with the temperature control surface 11 and a thermal disturbance occurs such that heat is transferred between the temperature control surface 11 and the outside. However, it is possible to suppress the influence of disturbance and to adjust the temperature of the temperature control surface 11 uniformly.

Further, in the present embodiment, as described above, since a material having flexibility is used for the heat conductive sheet 12, an appropriate curved surface can be formed even when coming into contact with the human body, thereby impairing comfort. There is no.

(Second Embodiment)
Next, a second embodiment of the present disclosure will be described. In the said 1st Embodiment, although it comprised so that the thermal resistance between the heat-source part 10 and the temperature control part 11a might be adjusted with the thermal resistance adjustment part 14, in this 2nd Embodiment, the several heat conductive sheet 12 is comprised. The thermal resistance between the heat source unit 10 and the temperature control unit 11a is adjusted by changing the shape and material.

FIG. 5 shows an example in which the thicknesses of the plurality of heat conductive sheets 12 are varied. As shown in FIG. 5, when the thicknesses of the plurality of heat conductive sheets 12 are made different, the heat resistance can be reduced by increasing the thickness of the heat conductive sheet 12, and the heat resistance can be decreased by reducing the thickness of the heat conductive sheet 12. Can be big.

Although not shown, the widths of the plurality of heat conductive sheets 12 may be different, or the materials of the plurality of heat conductive sheets 12 may be different. When making the widths of the plurality of heat conductive sheets 12 different, it is possible to reduce the thermal resistance by increasing the width of the heat conductive sheet 12, and it is possible to increase the thermal resistance by reducing the width of the heat conductive sheet 12. Further, when different materials are used for the plurality of heat conductive sheets 12, the thermal resistance can be reduced by using a material having a high thermal conductivity, and the thermal resistance can be increased by using a material having a high thermal conductivity.

In the second embodiment, since the thermal resistance between the heat source unit 10 and the temperature adjustment unit 11a is uniformly adjusted by the heat conductive sheet 12 itself, adjustment of the thermal resistance by the thermal resistance adjustment unit 14 is not necessary, It is not necessary to install the thermal resistance adjusting unit 14. For this reason, it is possible to directly exchange heat between the heat source unit 10 and the heat conductive sheet 12.

When the thermal resistance between the heat source unit 10 and the temperature control unit 11a is uniformly adjusted by the thermal conductive sheet 12 itself as in the second embodiment, the thermal conductive sheet 12 is the same as the thermal resistance adjustment unit 14. Plays a function. Of course, the adjustment of the thermal resistance by the thermal conductive sheet 12 and the adjustment of the thermal resistance by the thermal resistance adjustment unit 14 may be used together to complement each other with the function of adjusting the temperature control surface 11 to a uniform temperature.

(Third embodiment)
Next, a third embodiment of the present disclosure will be described. In the said 1st Embodiment, although it comprised so that the heat resistance between the heat source part 10 and the temperature control part 11a might be adjusted with the heat resistance adjustment part 14, in this 3rd Embodiment, the heat source part 10 and the temperature control part The temperature control unit 11a is adjusted according to the thermal resistance between it and 11a. For example, what is necessary is just to adjust the area of the temperature control part 11a according to the thermal resistance between the heat source part 10 and the temperature control part 11a.
