[Technical field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to a heat exchange device for the human body. [Background technology]

[0002] When workers perform various tasks in a radioactive contaminated environment, they wear protective clothing to prevent internal exposure and body contamination. However, when the environment in which the workers perform their tasks while wearing protective clothing is, for example, high temperature and high humidity, the risk of exhaustion and heat stroke is very high, and depending on the type of work, the workers may only be able to perform the tasks for a short period of time. For this reason, it may be considered to wear cooling clothing equipped with a fan. For example, Patent Document 1 describes such a technology. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-113371 A Summary of the Invention [Problem to be solved by the invention]

[0004] The air conditioning unit of Patent Document 1 includes a Peltier element, a metal plate joined to the Peltier element, and a metal heat exchange plate that is joined to the metal plate and placed inside the clothing. However, the use of such air-conditioned clothing is not permitted for work in radiation-controlled areas. In other words, air circulation between the outside and inside of the clothing is not permitted, and even if a fan is attached to the clothing, air only circulates inside the clothing, making it difficult to cool the worker's body. In addition, it is possible to wear an airline suit that can be used in radiation-controlled areas, but the airline suit has an air hose connected to it, which limits the work range.

[0005] The present disclosure is intended to solve the above-mentioned problems, and aims to provide a heat exchange device for a human body that improves the working environment of a worker. [Means for solving the problem]

[0009] Preferred embodiments of the present disclosure will be described in detail below with reference to the drawings. Note that the present disclosure is not limited to these embodiments, and when there are multiple embodiments, the present disclosure also includes a configuration in which each embodiment is combined. In addition, the components in the embodiments include those that a person skilled in the art can easily imagine, those that are substantially the same, and those that are within the so-called equivalent range.

[0010] <Protective clothing> FIG. 1 is a schematic cross-sectional view showing a protective suit equipped with a heat exchanger for a human body according to the present embodiment.

[0011] In this embodiment, the protective clothing is worn by a worker when performing various tasks in a radiation controlled area to prevent internal exposure and body contamination. However, the protective clothing is not limited to being used in a radiation controlled area and is used to protect the body from hazards, and can also be used as, for example, chemical protective clothing or biohazard protective clothing.

[0012] As shown in FIG. 1, a heat exchange device for a human body 11 is attached to a protective suit 12 when in use.

[0013] The heat exchange device for a human body 11 includes a cooling / heating unit 21, a heat exchange unit 22, a power supply unit 23, and a removable unit 24. The details of the heat exchange device for a human body 11 will be described later. The protective suit 12 is interposed between the cooling / heating unit 21 and the heat exchange unit 22.

[0014] The protective clothing 12 is, for example, a radiation protection suit, which is worn when working in a place where there is a risk of contact with radioactive materials or exposure to radiation to prevent damage to the human body. The protective clothing 12 is, for example, Tyvex (registered trademark) or anorak.

[0015] As described below, the cooling / heating unit 21 is attached to a cooling / heating suit 31. The worker first wears the cooling / heating suit 31 with the cooling / heating unit 21 attached. The worker then wears the protective suit 12 over the cooling / heating suit 31. The worker then wears the heat exchange unit 22 over the cooling / heating unit 21 with the protective suit 12 interposed between them.

[0016] By wearing the protective suit 12 equipped with the human body heat exchange device 11, the worker can suppress damage to the human body caused by radiation by the protective suit 12. In addition, by wearing the protective suit 12, the worker's body can be cooled or heated by the human body heat exchange device 11 and maintained at an appropriate temperature.

[0017] <Heat exchange device for human body> FIG. 2 is a block diagram showing the electrical system of the heat exchange device for the human body.

[0018] As shown in Figs. 1 and 2, the human body heat exchange device 11 includes the cooling / heating unit 21, the heat exchange unit 22, the power supply unit 23, and the detachable unit 24, as described above.

[0019] The cooling / heating unit 21 is attached to a cooling / heating suit 31. The cooling / heating suit 31 is preferably a vest, but may be a short-sleeved or long-sleeved shirt, for example. The cooling / heating unit 21 has a housing 32, a heat transfer section 33, and a fluid circulation unit 34.

[0020] The housing 32 has a hollow rectangular parallelepiped shape, but the shape is not limited thereto. The housing 32 is fixed to the back part of the cooling and heating suit 31. The back part of the cooling and heating suit 31 is the part that is located on the back side when the worker wears the cooling and heating suit 31. A heat transfer part 33 and a fluid circulation unit 34 are arranged inside the housing 32. The heat transfer part 33 and the fluid circulation unit 34 are connected to each other.

[0021] The heat transfer section 33 has a flat plate shape and is fixed to a flat surface on one side (the left side in FIG. 1) of the housing 32. The heat transfer section 33 is not limited to a flat plate shape, and may be curved. It is preferable that the surface of the heat transfer section 33 is exposed from the housing 32, but it may be fixed to the inner surface of the housing 32 so that it is not exposed. The heat transfer section 33 is, for example, a metal plate, and has a heat dissipation function and a heat absorption function as heat transfer performance. The heat transfer section 33 and the tank 41 may be of an integral structure, in which case the heat transfer section 33 may have a mesh-like heat transfer path that increases the contact area between the fluid circulating inside the tank 41 and the heat transfer section 33.

[0022] The fluid circulation unit 34 includes a tank 41, a circulation path 42, and a pump 43. The tank 41 is fixed to the rear surface of the heat transfer unit 33 or to the inner surface of the housing 32 so as to be in contact with the heat transfer unit 33. The tank 41 stores a fluid (e.g., water) therein. The circulation path 42 is a path for circulating the fluid stored in the tank 41. The circulation path 42 is, for example, a flexible tube. One end of the circulation path 42 in the longitudinal direction is connected to the upper part of the tank 41, and the other end of the circulation path 42 is connected to the lower part of the tank 41. One end and the other end of the circulation path 42 extend to the outside of the housing 32 by penetrating the upper and lower parts of the housing 32. The circulation path 42 has an intermediate portion attached to the heating and cooling suit 31. In this case, it is preferable that the circulation path 42 has a predetermined length and is disposed in a wide area of ​​the heating and cooling suit. The pump 43 circulates the fluid in the tank 41 through the circulation path 42. The pump 43 is attached to the tank 41. When the pump 43 is operated, the fluid in the tank 41 is supplied to the circulation path 44 from the bottom, flows through the circulation path 42, and then returns to the inside of the tank 41 from the top.

[0023] The heat exchange unit 22 has a housing 51, a heat transfer section 52, a thermoelectric element 53, fins 54, a ventilation passage 55, and a fan 56. The heat transfer section 52 may be provided integrally with the housing 51, but is preferably provided separately and thermally separated from the housing 51.

[0024] The housing 51 has a hollow rectangular parallelepiped shape, but the shape is not limited thereto. The housing 51 has a heat transfer section 52, a thermoelectric element 53, fins 54, and a ventilation passage 55 disposed therein. The housing 51 has a lower opening 61 formed at its lower end and an upper opening 62 formed at its upper end.

[0025] The heat transfer section 52 has a flat plate shape and is fixed to a flat surface on one side (the right side in FIG. 1) of the housing 51. The heat transfer section 52 is not limited to a flat plate shape, and may have a curved shape. It is preferable that the surface of the heat transfer section 52 is exposed from the housing 51, but the surface may be fixed to the inner surface of the housing 51 so as not to be exposed. The thermoelectric element 53 has a flat plate shape and is fixed to the back surface of the heat transfer section 52. The thermoelectric element 53 is, for example, a Peltier element. The Peltier element is formed by joining P-type and N-type semiconductors to metal electrodes, and when a current is passed in one direction, one surface is heated and the other surface is cooled, and when the direction of the current is reversed, the heated surface and the cooled surface are reversed.

[0026] The thermoelectric element 53 has a plurality of fins 54 connected to a rear surface of the inside of the housing 51. The plurality of fins 54 are fixed to be perpendicular to the rear surface of the thermoelectric element 53, and are arranged at intervals in the vertical and horizontal directions. The ventilation passage 55 is arranged in the vertical direction inside the housing 51. That is, the ventilation passage 55 is a passage from the lower opening 61 to the upper opening 62 inside the housing 51. The thermoelectric element 53 and the fins 54 are arranged in the ventilation passage 55. The fan 56 is provided in the lower opening 61 at the bottom of the housing 51. When the fan 56 is operated, outside air is supplied from the lower opening 61 to the ventilation passage 55 and rises up the ventilation passage 55. After that, the air in the ventilation passage 55 comes into contact with the thermoelectric element 53 and the fins 54, and is discharged to the outside from the upper opening 62.

[0027] Although the housing 51 is hollow and has the heat transfer section 52, the thermoelectric element 53, the fins 54, and the ventilation passages 55 disposed therein, the present invention is not limited to this shape. For example, the housing 51 may be shaped like a mesh box and have the heat transfer section 52, the thermoelectric element 53, and the fins 54 disposed therein. Furthermore, the housing 51 may be shaped like a plate and at least the thermoelectric element 53 and the heat transfer section 52 disposed on the flat surface.

[0028] The power supply unit 23 is provided in the housing 51 of the heat exchange unit 22. The power supply unit 23 can supply power to the electric components on the cooling / heating unit 21 side and the electric components on the heat exchange unit 22 side. The heat exchange unit 22 has a control device 71 and an operation device 72 provided in the housing 51. The operation device 72 is connected to the control device 71, which is connected to the power supply unit 23 and is also connected to the thermoelectric element 53 and the fan 56. Therefore, the power supply unit 23 can supply power to the control device 71, and can also supply power to the operation device 72, the thermoelectric element 53, and the fan 56 via the control device 71.

[0029] The cooling / heating unit 21 and the heat exchange unit 22 are provided with a non-contact power supply device 73. The non-contact power supply device 73 is a remote system that wirelessly transmits power and signals at the same time. That is, the non-contact power supply device 73 can supply power from the power supply unit 23 provided on the heat exchange unit 22 side and a command signal from the control device 71 to the cooling / heating unit 21 side. The non-contact power supply device 73 has a transmission unit 74 provided on the cooling / heating unit 21 and a transmission unit 75 provided on the heat exchange unit 22. The transmission unit 74 is connected to the control device 71, and the transmission unit 75 is connected to the pump 43. The non-contact power supply device 73 can transmit power and signals between the transmission unit 74 of the cooling / heating unit 21 and the transmission unit 75 of the heat exchange unit 22. Therefore, the power supply unit 23 can supply power from the control device 71 to the pump 43 via the non-contact power supply device 73 (transmission units 74, 75).

[0030] Moreover, the worker can transmit various command signals to the control device 71 by operating the operation device 72. Upon receiving a command signal from the operation device 72, the control device 71 can control the activation and stop of the thermoelectric element 53, the activation and stop of the fan 56, and the activation and stop of the pump 43. Furthermore, the control device 71 can switch between cooling and heating by the thermoelectric element 53 by controlling the direction of the current to the thermoelectric element 53 in response to the command signal from the operation device 72.

[0031] In this embodiment, the power supply unit 23 and the control device 71 are provided on the heat exchange unit 22 side, but the power supply unit 23 and the control device 71 may be provided on the cooling / heating unit 21 side, and the non-contact power supply device 73 may transmit power and signals to the heat exchange unit 22. Also, the power supply unit 23 and the control device 71 may be provided on the cooling / heating unit 21 side and the heat exchange unit 22 side, and the non-contact power supply device 73 may be eliminated.

[0032] The detachable unit 24 is capable of attaching and detaching the cooling / heating unit 21 and the heat exchange unit 22 such that the heat transfer unit 33 of the cooling / heating unit 21 and the heat transfer unit 52 of the heat exchange unit 22 face each other. Specifically, the detachable unit 24 is capable of attaching and detaching the cooling / heating unit 21 and the heat exchange unit 22 such that the heat transfer unit 33 and the heat transfer unit 52 face each other across the protective suit 12. Note that the heat transfer unit 52 may be eliminated by providing the thermoelectric element 53 with a heat transfer function, and the detachable unit 24 may be capable of attaching and detaching the cooling / heating unit 21 and the heat exchange unit 22 such that the heat transfer unit 33 and the thermoelectric element 53 face each other across the protective suit 12.

[0033] The detachable portion 24 has adsorption portions 81 and 82. The adsorption portions 81 and 82 connect the cooling / heating unit 21 and the heat exchange unit 22 at a position where the heat transfer portion 33 and the heat transfer portion 52 face each other. The adsorption portions 81 and 82 are permanent magnets. However, the adsorption portions 81 and 82 may be electromagnets operated by a control device.

[0034] <Modifications of the heat exchange device for the human body> 3 is a schematic cross-sectional view showing a modified example of a protective suit to which a heat exchanger for a human body is attached. Note that members having the same functions as those in the above-mentioned embodiment are given the same reference numerals and detailed description thereof is omitted.

[0035] 3, the heat exchange device for a human body 11A is used by being attached to a protective suit 12. The heat exchange device for a human body 11A includes a cooling / heating unit 21A, a heat exchange unit 22A, a power supply section 23, and a detachable section 24A.

[0036] The cooling / heating unit 21A is attached to a cooling / heating suit 31. The cooling / heating unit 21A has a housing 32, a heat transfer section 33A, and a fluid circulation unit 34. It is preferable that the surface of the heat transfer section 33A is exposed from the housing 32, but the heat transfer section 33 may be fixed to the inner surface of the housing 32 so as not to be exposed. The heat transfer section 33 is, for example, a metal plate, and has a heat dissipation function and a heat absorption function as heat transfer performance.

[0037] The heat exchange unit 22A has a housing 51, a heat transfer section 52A, a thermoelectric element 53, fins 54, a ventilation passage 55, and a fan 56. It is preferable that the front surface of the heat transfer section 52A and the thermoelectric element 53 are exposed from the housing 51, but they may be fixed to the inner surface of the housing 51 so as not to be exposed. The thermoelectric element 53 is fixed to the back surface of the heat transfer section 52A. The thermoelectric element 53 is, for example, a Peltier element.

[0038] The detachable part 24A is capable of attaching and detaching the cooling / heating unit 21 and the heat exchange unit 22A such that the heat transfer part 33 of the cooling / heating unit 21 and the heat transfer part 52A of the heat exchange unit 22A face each other. Specifically, the detachable part 24 is capable of attaching and detaching the cooling / heating unit 21 and the heat exchange unit 22A such that the heat transfer part 33 and the heat transfer part 52A face each other with the protective suit 12 interposed therebetween.

[0039] The detachable part 24 has a fitting part 91. The fitting part 91 connects the cooling / heating unit 21A and the heat exchange unit 22A at a position where the heat transfer part 33A and the heat transfer part 52A face each other. The fitting part 91 preferably has an uneven shape for positioning, but is not limited to this shape. The cooling / heating unit 21A and the heat exchange unit 22A are connected by fitting the heat transfer part 33A and the heat transfer part 52A to each other via the protective suit 12 by the fitting part 91.

[0040] Further, the attachment / detachment section 24 has a locking device 92. The locking device 92 has a plurality of locking claws 93. The plurality of locking claws 93 are provided around the heat transfer section 52A. The plurality of locking claws 93 connect the cooling / heating unit 21A and the heat exchange unit 22A at a position where the heat transfer section 33A and the heat transfer section 52A face each other. The cooling / heating unit 21A and the heat exchange unit 22A are connected by the heat transfer section 33A and the heat transfer section 52A being locked with each other via the protective suit 12 by the plurality of locking claws 93.

[0041] Although the fitting portion 91 and the locking device 92 are provided as the detachable portion 24, it is sufficient to provide at least one of them.

[0042] <How to wear protective clothing> Figure 4 is a schematic diagram showing a worker wearing the cooling and heating suit, Figure 5 is a schematic diagram showing a worker wearing a radiation protection suit over the cooling and heating suit, and Figure 6 is a schematic diagram showing a worker wearing a heat exchange unit on the radiation protection suit.

[0043] As shown in FIG. 4, the cooling / heating unit 21 is attached to the back side of the cooling / heating suit 31. The worker wears the cooling / heating suit 31 with the cooling / heating unit 21 attached. At this time, the cooling / heating unit 21 is exposed to the back side of the cooling / heating suit 31 worn by the worker. As shown in FIG. 5, the worker wears protective clothing 12 over the cooling / heating suit 31. At this time, the cooling / heating unit 21 of the cooling / heating suit 31 worn by the worker is covered by the protective clothing 12. As shown in FIG. 6, the worker attaches the heat exchange unit 22A to the cooling / heating unit 21 over the protective clothing 12. In this case, it is preferable to have another worker attach the heat exchange unit 22A. The heat exchange unit 22A is attached to the cooling / heating unit 21 of the cooling / heating suit 31 with the protective clothing 12 sandwiched therebetween. The protective clothing 12 prevents the worker from being exposed to radiation.

[0044] The heat exchanger 11 for human body is operated by a worker wearing the protective suit 12 to which the heat exchanger 11 for human body is attached, or by another worker operating the operating device 72. That is, when the worker wears the protective suit 12 and works in a high-temperature environment, the worker operates the operating device 72 to operate the heat exchanger 11 for human body in a cold mode. That is, as shown in FIG. 1, the flat surface of the heat transfer section 52 of the thermoelectric element 53 on the heat transfer section 33 side is set as a cooling surface, and the fin 54 side is set as a heating surface. Then, the cooling surface of the thermoelectric element 53 contacts the heat transfer section 33 through the heat transfer section 52, so that the cold heat of the thermoelectric element 53 is transferred to the fluid in the tank 41 through the heat transfer sections 52 and 33, and the temperature of the fluid is reduced. Here, by operating the fluid circulation unit 34, the cooled fluid in the tank 41 circulates through the circulation path 42, and cools the body of the worker wearing the cooling and heating suit 31 through the circulation path 42. Furthermore, by operating the fan 56, outside air is supplied to the ventilation passage 55 and cools the heated thermoelectric element 53 via the fins 54.

[0045] On the other hand, the operator operates the operating device 72 to operate the human body heat exchange device 11 in a heating mode. That is, the flat surface of the thermoelectric element 53 on the heat transfer section 33 side is set as a heating surface, and the fin 54 side is set as a cooling surface. Then, the heating surface of the thermoelectric element 53 comes into contact with the heat transfer section 33 via the heat transfer section 52, so that the heat of the thermoelectric element 53 is transferred to the fluid in the tank 41 via the heat transfer sections 52 and 33, and the temperature of the fluid increases. Here, by operating the fluid circulation unit 34, the heated fluid in the tank 41 circulates through the circulation path 42, and the body of the operator wearing the cooling and heating suit 31 is heated via the circulation path 42. Also, by operating the fan 56, outside air is supplied to the ventilation passage 55, and the thermoelectric element 53, whose temperature has been reduced, is heated via the fin 54.

[0046] The worker puts on the protective clothing 12 and activates the human body heat exchanger 11, switching between a cooling mode or a heating mode according to the working environment. Therefore, the worker is cooled or heated according to the working environment, and the body can be maintained at an appropriate temperature.

[0047] [Effects of this embodiment] The heat exchange device for the human body in the first embodiment comprises a cooling / heating unit 21, 21A having a heat transfer section 33, 33A and a fluid circulation unit 34 connected to the heat transfer section 33, 33A, a heat exchange unit 22, 22A having a thermoelectric element 53, a power supply section 23 capable of supplying power to the fluid circulation unit 34 and the thermoelectric element 53, and a detachable section 24, 24A capable of attaching and detaching the cooling / heating unit 21, 21A and the heat exchange unit 22, 22A so that the heat transfer section 33, 33A and the thermoelectric element 53 face each other.

[0048] According to the first embodiment of the human body heat exchange device, when an electric current is applied to the thermoelectric element 53 of the heat exchange unit 22, 22A, the heat (cold heat) of the thermoelectric element 53 is transferred from the heat transfer section 52, 52A through the heat transfer section 33, 33A of the cooling / heating unit 21, 21A to the fluid of the fluid circulation unit 34, thereby cooling or heating the human body. By circulating the fluid through the fluid circulation unit 34, cold water or hot water is circulated, and the human body can be cooled or heated. This can improve the working environment of the worker.

[0049] Furthermore, because the heat exchange units 22, 22A can be freely attached and detached to the cooling / heating units 21, 21A by the attachment / detachment parts 24, 24A, the worker can put on the cooling / heating units 21, 21A, then put on the protective suit 12, and attach the heat exchange units 22, 22A to the cooling / heating units 21, 21A over the protective suit 12.

By providing the power supply unit 23 in the heat exchange unit 22, 22A, the cooling and heating unit 21, 21A can be made lighter. In addition, when the charge level of the battery serving as the power supply unit 23 decreases, the power supply unit 23 or the heat exchange unit 22, 22A can be easily replaced, and there is no need to take off the protective suit 12, improving workability.

[0054] The heat exchange device for a human body according to the sixth aspect is the heat exchange device for a human body according to any one of the first to fifth aspects, and further, the detachable part 24 has adsorption parts 81, 82 that connect the cooling / heating unit 21 and the heat exchange unit 22 at a position where the heat transfer part 33 and the thermoelectric element 53 face each other.
