PURPOSE:To permit the control of the transfer of heat and the insulation of heat to make living environment comfortable by a method wherein a loop, whose vertical parts are connected thermally to an outer wall and an inner wall while a control valve is provided in the horizontal part of the lower side of the loop, is provided between the outer wall and the inner wall. CONSTITUTION:A wall body is constituted of a looped heat pipe 5, whose vertical parts contains wicks are connected thermally to an outer wall body 6 and an inner wall body 7 utilized as a heat absorbing section and a heat dissipating section, and a space 8 between both wall bodies while heat insulating material 9 is inserted into the space 8 if necessary and a solenoid valve 10, controlling the flow of heating medium 3, is provided in the lower horizontal part of the loop. The solenoid valve 10 is controlled by a controller 14 inputting a temperature signal from an indoor temperature sensor 12 and an outdoor temperature sensor 13. The transfer of heat is controlled by comparing the temperature shown by an outdoor temperature sensor 13 provided in the outer wall body 6 with a temperature shown by an indoor temperature sensor 12 provided in the inner wall body by a controller 14. When heat is desired to be transferred from a wall having higher temperature to another wall having a lower temperature, the control valve is opened by the controller to transfer heat and make the indoor side or an indoor environment comfortable but when the transfer of heat is not desired, the control valve is closed to prevent the invasion of heat and keep the indoor environment comfortable.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wall of a building, and particularly to a wall suitable for controlling heat transfer between a building and the outside air.

[Prior Art] In general, the temperature difference between the indoor temperature and the outside temperature of a house differs greatly between winter and summer, and between day and night. During the daytime in winter, sunlight hits the exterior walls, so it is desirable to transfer that heat indoors to raise the indoor temperature. On the other hand, at night, the outer wall temperature drops, so it is desirable to stop the transfer of heat. During the daytime in summer, the temperature of the outside walls is high and it is desirable to stop the transfer of heat.On the other hand, at night, the temperature of the outside walls is lower, so it is desirable to transfer indoor heat to the outside walls and lower the indoor temperature.

In the conventional wall body, a typical conventional heat pipe 4 is thermally coupled between the inside of the outer wall 6 and the inside of the inner wall 7, as shown in FIG. The lower end of the heat pipe 4 becomes the heating side due to heat input from the outer wall 6, and the second end becomes the heat radiation side and radiates heat to the inner wall 7. When the heat pipe 4 is used in a nearly vertical state like this, the internal liquid evaporates and rises, so the heat also moves from below, and heat can only be transferred when the temperature of the outer wall 6 is higher than the inner wall 7. Therefore, when the temperature of the inner wall 7 is higher than that of the outer wall 6, heat transfer becomes impossible.

[Challenges to be Solved by the Invention] The above-mentioned prior art can only transfer heat in one direction. However, if two heat pipes are used, heat can be transferred in both directions, but they cannot be shut down when heat transfer is not necessary.

In addition, heat transfer can be stopped when heat transfer is not needed, and consideration must be given to the direction of heat transfer and stagnancy.If the design is designed to bring in heat indoors in the winter, the temperature of the outer wall will be high in the summer. In this case, there is a problem that heat transfers indoors, worsening the indoor living environment.

The purpose of the present invention is to determine the direction of heat transfer between walls and the direction of heat transfer/
The second step is to control insulation and create a comfortable living environment.

(Means for solving the problem P9:1 The above purpose is to control the vertical joint between the outer wall and the inner wall, form a loop, and thermally connect the vertical part to the outer wall and the inner wall, and the lower horizontal joint. This is achieved by having a R Ken (Sta Beat Vibe).

1. The object is to provide an outer wall temperature sensor provided on the wall surface of the outer wall opposite to the heat pipe, an inner wall temperature sensor provided on the inner wall surface opposite to the heat pipe, the outer wall temperature sensor and the A control device that compares the temperatures detected by the outer wall temperature sensor and opens the control valve when the heat is transferred from the higher temperature to the lower temperature, and closes the control valve when the heat is not transferred. achieved.

The above object is achieved by providing a wick inside the vertical part of the heat pipe.

[Function] According to the above configuration, the heat pipe is located between the outer wall and the inner wall, forming a loop, and the vertical portion is thermally connected to the outer wall and the inner wall, so that the heat pipe can be heated from either direction of the outer wall or the inner wall. It's too hot to move. Heat transfer/insulation can be controlled by opening and closing a control valve provided at the lower horizontal portion of the neat pipe.

and an outer wall temperature sensor provided on the outer wall surface of the outer wall,
Compare the temperatures detected by an inner wall temperature sensor installed on the outer wall of the inner wall, and if it is desirable to transfer heat from the higher temperature to the lower temperature, the control device opens the control valve to transfer the heat to the inner wall. By making the environment on the side more comfortable and closing the control valve when it is not desired, unnecessary heat input can be prevented and the environment on the inner wall side can be made more comfortable.

Furthermore, the wick of the heat pipe is filled with a liquid phase heating medium, and when heat is input from an external heat source, the heating medium evaporates, and the liquid level on the evaporation surface is depressed below the wick surface, generating capillary pressure. This capillary pressure acts as a pump to supply a liquid phase heat medium to the evaporation surface, and evaporation is actively carried out, increasing the heat transport capacity.

Since the vertical part of the heat pipe is thermally coupled to the outer and inner walls, providing a wick on the vertical part of the heat pipe increases the ability to transport heat from the outer wall to the inner wall via the heat pipe, or from the inner wall to the outer wall. increases.

[Example] Embodiments of the present invention will be described with reference to the drawings.

The configuration of this embodiment will be explained with reference to FIG.

An outer wall 6, an inner wall 7, and a space 8 sandwiched between the two walls are thermally coupled to the vertical portion of the loop-shaped heat pipe 5 provided with the wick to become a heat absorption section or a heat dissipation section. can be,

As shown in FIG. 3, at night in winter, the electromagnetic valve 10 is closed to prevent heat from escaping, stopping the transfer of heat, and causing the entire wall to function as a heat insulating wall.

As shown in Figure 4, at night in summer, when the outside temperature is cooler than the indoor temperature, when the solenoid valve] 0 is opened, the heat pipe 5
The internal heat medium 3 circulates from the inner wall 7 to the outer wall 6, radiating indoor heat to the outside air. During the daytime in summer, when the temperature of the outer wall is high and you do not want to let heat into the room, close the solenoid valve O to stop the transfer of heat and make the entire wall function as a heat insulating wall.

By providing a wick only in the vertical portion of the loop-shaped heat pipe 5 that is thermally connected to the outer wall 6 and inner wall 7, heat transport ability from the outer wall to the inner wall via the heat pipe or from the inner wall to the outer wall is improved. increases.
