る。2. Description of the Related Art In a building such as a general house, when heating or cooling an indoor space, it is necessary to prevent heat energy or cold energy in the room from escaping to the outside as much as possible. Therefore, a so-called wall structure such as a wall or a floor or a ceiling that separates the room from the outdoors should have a structure with good heat insulation. That is, the heat radiation from the high temperature space to the low temperature space between the indoor space and the outdoor space is kept as small as possible.

In this case, the wall structure is desired to have a structure with good heat dissipation. In addition, when trying to warm the room with solar heat, it is preferable to enhance the heat dissipation of the wall structure so that heat can be efficiently supplied from the outdoor space to the indoor space. Become.

ようにしておくことが要求される。As described above, in the wall structure of a building, high heat dissipation is required depending on the situation, or conversely,
There are cases where low heat dissipation is required. for that reason,
If the wall structure is simply made of a heat insulating material or a highly heat radiating material, it is not possible to sufficiently cope with the case where the opposite property is required as described above. Therefore, it is required to control the heat radiation property of the same wall structure according to the situation.

シャッターなどもある。Conventionally, as a method of controlling the heat dissipation of the wall structure, for example, there is a method of attaching a curtain to a window. When the curtain is closed, the air layer existing between the curtain and the window glass functions as a good heat insulating material, so that the wall structure has a high heat insulating property, that is, a low heat radiating property. However, when the curtain is opened, the indoor space and the outdoor space are separated from each other only by the window glass, so that the heat dissipation is enhanced. As a structure having the same function as the curtain, there are shoji screens and shutters.

由に制御することが要求される場合がある。It is not only the wall structure of the building that is required to control the heat dissipation as described above. For example, in recent years, the use of various heat storage devices has been increasing for the purpose of energy saving or leveling of electric power. In such heat storage devices, it is possible to freely control the amount of heat released from the heat source to the external space. I need to leave. That is, at the stage of storing heat, it is necessary to block the heat radiation from the heat source to the external space, and at the stage of utilizing the stored heat for heating etc., it is necessary to make the heat radiation from the heat source to the external space good. .. In addition, in various mechanical devices, between the high temperature space and the low temperature space,
In some cases, it is required to freely control the transfer of heat, that is, the heat dissipation property, by increasing or decreasing it.

対流と自然対流との状態変更、あるいは、熱リークの有
無などで行っていることになる。Generally, as a method of controlling heat dissipation, for example, the heat transfer property, that is, heat dissipation is obtained by forcibly disturbing the temperature boundary layer existing between the high temperature space and the low temperature space by an air flow or a water flow. It is conceivable that the heat dissipation is controlled by increasing the strength and adjusting the strength of the air flow or water flow. In addition, a material with high thermal conductivity such as metal is brought into contact with a heat source or a cold heat source to forcibly leak heat or cold heat to enhance heat radiation, and the contact or non-contact of this metal is operated to release heat. It is also considered to control sex. In these methods, the heat dissipation is controlled by changing the state of forced convection and natural convection, or by the presence or absence of heat leak.

スの間に空気層が存在するだけでは、完全な断熱性は望
めない。However, the conventional heat dissipation control method described above has a problem that the heat dissipation cannot be efficiently controlled. That is, for example, in the method of attaching the curtain to the window of the building described above, the heat dissipation is good when the curtain is open, but even when the curtain is closed, an air layer is present between the curtain and the window glass. It is not possible to expect perfect heat insulation if it exists.

不可能であった。Further, in order to enhance the heat insulating property, various known heat insulating materials may be used, but since the heat transfer characteristics of the heat insulating material itself are constant, the above-mentioned air flow and water flow are supplied on the surface of this heat insulating material. However, it is impossible to greatly change the overall heat dissipation even if the heat conductive material is brought into contact. in this way,
In the conventional method, although it is possible to control the heat radiation property with a certain amount of heat radiation property, there is a very low heat radiation property, that is, an almost completely adiabatic state, and a good heat radiation property. It was impossible to control the heat dissipation in a wide range.

It is preferable to use a highly safe gas that has no When the heat dissipation control body is often used in an adiabatic state having relatively low heat dissipation, it is preferable to use a gas having a low thermal conductivity as the gas.

性を示すことになる。When the heat dissipation controller is arranged between the high temperature space and the low temperature space, the heat transferability or heat dissipation between the two spaces is determined by the heat dissipation of the heat dissipation controller. If the gas in the airtight space is exhausted in a state where the airtight space of the heat dissipation control body is filled with the porous body having continuous pores, the continuous pores of the porous body become a vacuum state. Since no heat is transferred in the vacuum portion and the heat transfer property of the porous body itself is low, the heat release property of the heat dissipation control body is extremely low. In other words, it shows a high degree of heat insulation.

で変化させることが可能になる。When a gas is introduced into the airtight space of the heat dissipation control body, the degree of vacuum in the airtight space is lowered. If the degree of vacuum changes even slightly, the thermal conductivity changes extremely sensitively, so the thermal conductivity of the heat dissipation control body also changes significantly. That is,
By adjusting the degree of vacuum in the airtight space, that is, adjusting the amount of gas sent into the airtight space, the same heat dissipation control body can freely control heat dissipation from a state with extremely low heat dissipation to a state with better heat dissipation. You can do it. Intake and exhaust of gas can be controlled quickly and precisely with a vacuum pump, etc.
