Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an indoor temperature equalizing system capable of eliminating a vertical temperature unevenness in a heated room and ensuring a comfortable indoor environment.

[0002]

[Prior Art]

 In the room where heating is being performed, the warmed and lightened air rises and moves to the upper part of the room. Instead, cold air descends and accumulates near the floor. Therefore, in such a case, the temperature near the floor becomes low and does not warm up easily, which makes the indoor environment uncomfortable and, in some cases, warms up only the face and head. That was the opposite of the condition of head cold foot fever, which is suitable for human working environment. Therefore, in the past, for example, by rotating the ceiling fan or blowing air from the air outlet on the wall, the air in the room is stirred, or the air in the room is forced to circulate vertically by a circulator or the like. Then, the warmed air was moved downward to make the room temperature uniform.

[0003]

[Problems to be solved by the device]

 However, as described above, in the case of the conventional uniform room temperature, which is performed by sending warm air from the wall surface or using a means such as a ceiling fan or a circulator, the running cost is reduced because power is required. In addition to this, there is a problem in that when the air is blown from the wall surface, the noise or wind hits the person and causes discomfort to the person near the blower opening.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an indoor temperature equalizing system that does not require running costs, is maintenance-free, and does not cause discomfort to surrounding people. Has a purpose.

[0005]

[Means for Solving the Problems] As a means for solving the above problems, an indoor temperature equalizing system of the present invention is configured such that a plurality of wick-type heat pipes are attached to a heat absorption / radiation panel at predetermined intervals. It is characterized in that the wick type heat pipes are installed substantially vertically in a room where the lower ends of the wick type heat pipes are located near the floor and the upper ends thereof are located near the ceiling.

Further, each of the wick type heat pipes may be formed by connecting a plurality of short wick type heat pipes so that heat can be transferred in the axial direction. Further, the inner wall surface of the room may be constituted by the heat radiation panel. Further, the heat absorption / dissipation panel can be used as a partition for partitioning the interior of the room.

[0007]

[Action]

 As described above, the heat radiation panel with a plurality of wick type heat pipes installed in a room where heating is performed has the lower end of each wick type heat pipe near the floor and its upper end near the ceiling. The wick-type heat pipe placed near the floor with a low temperature serves as a condensing part by being installed almost vertically so that the heat absorbed from the evaporating part on the upper end side encloses the operation inside the pipe. The liquid is heated and evaporated, becoming a vapor-phase working liquid (vapor) that descends to a low-temperature condensing part, where heat is taken away from the condensing part to condense and become a liquid-phase working liquid in the pipe. Forms a puddle at the bottom of the. Then, the working liquid in the liquid pool rises to the upper evaporation portion by the capillary force of the wick provided on the inner peripheral surface of the pipe, and is heated again and evaporated. The heat taken from the vapor of the working fluid in the condensation section is dissipated from the outer peripheral surface of the condensation section to heat the surrounding low temperature air. Therefore, heat is transferred from the upper part of the room, which is hot, to the lower part of the room, and the temperature distribution in the room in the vertical direction is made uniform.

Further, as the wick type heat pipe, if a plurality of short wick type heat pipes having a length within the capillary limit are connected so as to be capable of heat transfer in the length direction to form one wick type heat pipe, The heat transfer distance by the heat pipe can be extended without lowering the efficiency. Further, if the inner wall surface of the room is configured by the heat radiation panel, the room temperature can be made uniform without narrowing the indoor space. Furthermore, if the heat radiation panel is used as a partition for partitioning the interior of the room, the room temperature can be made uniform efficiently.

【Example】

 An embodiment of an indoor temperature equalizing system according to the present invention will be described below with reference to FIGS.

FIG. 1 and FIG. 2 show a first embodiment of the present invention. A heat absorbing / releasing panel 1 includes a plurality of heat pipes while two metal thin plates such as aluminum plates having high thermal conductivity are put together. The two heat pipes 2 are held substantially vertically at a predetermined interval, and each heat pipe 2 is in contact with the thin metal plate at the heating portion 2a on the upper end side and the heat radiating portion 2b on the lower end side so as to be able to transfer heat. Is installed in. The height of the heat absorbing / releasing panel 1 is such that when the heat radiating portion 2b on the lower end side of each heat pipe 2 provided in the panel is arranged near the floor surface, the heating portion 2a on the upper end side is near the ceiling. It is located almost vertically from the wall of the room.

As an example, the plurality of heat pipes 2 provided in the heat absorption / dissipation panel 1 have a wick type heat pipe 12 (see FIG. 2) having an inner diameter of about 25 mm and a length L of about 290 mm. , 10 pieces are connected in the axial direction to form a predetermined length. Each wick-type heat pipe 12 is provided with a wick 13 on the entire inner peripheral surface thereof, and a small-diameter cylindrical projection 12c having a narrowed outer diameter is formed on each evaporation portion 12a on the upper end side. Further, each condensing part 12b on the lower end side is provided with a recess 12d at the center of its end face, into which a protruding part 12c formed at the upper end of another wick type heat pipe 12 is fitted in a close contact state. Then, in the condensing part 12b at the lower end, a liquid pool 14 of the working liquid sealed in the wick type heat pipe 12 is formed, and the projections 12c at the upper end of the wick type heat pipe 12 on the lower side are formed. By fitting in the recess 12d at the lower end of the upper wick-type heat pipe 12, a wide area is brought into contact and connected.

Next, the operation of this embodiment configured as described above will be explained. By providing the heat-radiating / dissipating panel 1 in which a plurality of heat pipes 2 are incorporated in a room, the temperature of the upper part of the room can be controlled during heating. The heat absorbed from the high air through the heat absorption / dissipation panel 1 becomes the heating portion 2a of the plurality of wick type heat pipes 12 forming each heat pipe 2, and the upper end of the uppermost wick type heat pipe 12 It is transmitted to the evaporation unit 12a. In the uppermost wick type heat pipe 12 to which the heat is transferred, the working fluid contained in the wick 13 on the inner peripheral surface of the evaporating portion 12a is heated and vaporized to become vapor of the working fluid, and the lower temperature is Move to lower condenser 12b. Then, after the heat is taken away in the condensing part 12b to condense and return to the liquid-phase working liquid and collected in the liquid pool 14, the working liquid is moved upward by the capillary force of the wick 13 on the inner circumference. The cycle of moving to 12a, heating again, and evaporating is repeated. At this time, since the entire length of each wick type heat pipe 12 is set to be within the capillary limit of the wick type heat pipe in the top heat mode, a high heat transport capacity in the heat pipe in the top heat mode can be secured.

Then, when the temperature of the evaporation section 12a rises due to the heat transferred through the pipe material, the working fluid is heated and evaporated, and heat is transferred to the condensation section 12b as in the case of the uppermost wick type heat pipe 12. The heat is transferred to the wick type heat pipes 12 which are sequentially connected downward. At this time, since the projection 12c on the vaporizing part 12a side of each wick type heat pipe 12 is closely fitted and connected to the concave part 12d on the condensing part 12b side, a wide heat transfer area can be obtained and the axis line The heat transfer between the wick type heat pipes 12 connected in the direction can be efficiently performed.

When heat is transferred to the lowermost wick type heat pipe 12 which becomes the heat radiating portion 2b of the heat pipe 2, the temperature of the evaporation portion 12a similarly rises, the working fluid is heated and evaporated, and The heat that is released when the vapor moves downward and condenses in the condensing part 12b is transferred to the portion near the floor surface of the heat radiation panel 1 that is in contact with the condensing part 12b, and the heat in the surrounding air is reduced. Is radiated to.

As a result, the heat absorbed by the high temperature air in the upper part of the room is transferred to the low temperature part in the lower part of the room by the plurality of heat pipes 2 assembled in the heat radiation panel 1 and released. , It is possible to eliminate vertical temperature unevenness in the room.

The lower end on the side of the portion 22b is in contact with the floor surface, and the heating portion 22a on the upper end thereof is provided substantially vertically so as to be located near the ceiling.

Further, each heat pipe 22 is formed by connecting a plurality of wick type heat pipes having a short length in the axial direction to have a predetermined length, as in the first embodiment. The same operation as in the first embodiment is performed in the top heat mode.

During heating, the heating portion 22a at the upper end of the exposed portion of the heat pipe 22 on the indoor side absorbs heat from the hot air in the vicinity of the ceiling, and this heat is released below the heat releasing portion 22b. The heat can be transported to the inside of the room and the heat can be dissipated into the low temperature air near the floor surface, and the temperature distribution in the vertical direction in the room can be made uniform. Further, by embedding a part of the heat pipe 22 in the wall so as to be exposed, it can be provided without narrowing the indoor space, and it can be used as a decorative surface of the wall surface, making the room uncomfortable. Can be installed without.
