Description

[Detailed Description of the Invention] The present invention has a heat flow directionality and a temperature sieving function that allows heat to flow only in one direction and transfers heat only when the temperature exceeds a predetermined temperature. The present invention relates to a unidirectional heat exchanger and building components that effectively utilize heat exchanger plates.

In the field of heat handling, how to efficiently achieve heat transfer between different fluids is an important issue, but it may be advantageous to be able to selectively extract only the desired heat during heat transfer. . For example, when heat is transferred from one fluid to another, if the temperature of one fluid changes over time, the amount of heat transferred to the other fluid also changes over time, which may affect the efficiency of the thermal equipment. Losing the ability to drive properly,
In some cases, if the temperature of one fluid becomes lower than that of the other, a backflow of heat may occur and the function of the thermal device itself may collapse. This applies not only when the temperature of one of the fluids changes over time, but also when there are temperature differences depending on the location within the heat transfer area. That is, when heat is extracted from such a heat source that has temperature differences depending on the location, even if heat can be extracted from the high-temperature portion, heat may be radiated from the low-temperature portion. Therefore, when we intend to transfer heat from one side to the other, no matter what the situation is on one side, it is possible to select and transfer only the necessary heat to the other side. It would be very convenient if a hot surface could be formed.

The present invention has been made to meet this need.

As a heat transfer plate that satisfies this requirement, the present invention provides a hollow box with a plate-like outer shape, both wide sides of which are made of a thermally conductive material, and which extends in the lateral direction when the box is oriented vertically. By partitioning into multiple stages with a large number of partition walls made of heat insulating material that slope unidirectionally from one side to the other wide side, a large number of mutually independent cells extending in the lateral direction are formed, and an actuator is activated within each cell. A unidirectional heat transfer plate filled with fluid is used. As a heat exchanger that effectively utilizes the characteristics of these heat exchanger plates, a plurality of these heat exchanger plates can be used.
Adjacent heat exchange plates are arranged side by side with a predetermined interval and the slopes of the partition walls are opposite to each other. We have devised a heat exchanger with unidirectional heat flow that allows a heat exchange fluid to flow through the heat exchanger. Furthermore, the characteristics of this heat exchanger plate are utilized from another aspect, such that the heat exchanger plate is configured such that the partition wall has an inclination that rises toward the indoor side in the winter, and By attaching the roof to the building so that it has a slope that rises toward the outside, indoor heat is not radiated to the outside in the winter, but can be transferred indoors only when the outdoor temperature rises. On the other hand, in the summer, high-temperature outdoor heat does not transfer indoors, and only when the indoor temperature becomes higher can the heat be radiated outdoors, such as shutters and building exterior wall structures. It was devised.

The present invention will be specifically described below with reference to the drawings.

FIG. 1 shows the heat exchanger plate of the present invention, which has a plate-like outer shape, in a vertical position. The heat transfer surfaces are the wide sides 1a and 1b (1b is on the back of the figure and not shown in Figure 1), and the narrow sides 2a and 2b (2b is not shown in Figure 1) are insulating. It is composed of Reference numerals 3a and 3b are installation auxiliary plates attached above and below this heat transfer plate, and these are not used for heat transfer.

FIG. 2 is a cross-sectional view taken along the - line in FIG. 1, and shows the internal structure of the heat exchanger plate. As shown in the figure, a large number of partition walls 4 made of a heat insulating material extend horizontally when the heat exchanger plate is vertically oriented and slope unidirectionally from one wide side to the other wide side. By partitioning into two, a large number of mutually independent cells 5 extending in the lateral direction are formed, and a working fluid 6 is sealed in each cell 5.

Figure 3 is an enlarged illustration of one cell.As shown in the figure, each cell forms an airtight container that is elongated in the horizontal direction, and the side walls are the heat transfer surfaces of the wide sides 1a and 1b. , is formed of a partition wall 4 whose upper and lower surfaces are unidirectionally inclined.

To explain each member in more detail in the configuration example shown in FIGS. 1 to 3, the wide side 1a and 1b are made of a metal plate having good thermal conductivity, and the narrow side 2a and 2 are made of a metal plate having good thermal conductivity.
b uses a material with low thermal conductivity such as resin,
Forms a hollow box with a plate-like outer shape. The partition wall 4 for forming the cell 5 is made of a plate made of a heat insulating material such as plastic, and the plate is stretched from one wide side to the other wide side with an inclination in the same direction. In the illustrated state (the vertical state in which the auxiliary plate 3a is located above), the plate is inclined upward from the wide side 1b toward the wide side 1a.
When this is turned upside down (vertical state with the auxiliary plate 3b facing up), from the wide side 1a to the wide side 1b
The slope rises toward the plane of This heat exchanger plate is used in a state where the wide sides 1a and 1b are substantially perpendicular, and therefore, in each cell 5, the partition walls 4 forming the top and bottom surfaces are always in the same direction. It will be tilted. Each cell 5 is independent of each other, and each cell 5 contains a working fluid 6.
is selected from the group of water, alcohols, and organic or inorganic substances that condense and evaporate at the operating temperature of the heat exchanger plate. As mentioned above, since the lower surface of each cell 5 is unidirectionally inclined, the liquid portion of the working fluid 6 is always collected on one wide surface side by gravity. In the example shown in FIGS. 2 and 3, the liquid portion of the working liquid 6 is collected on the wide side 1b. In this heat exchanger plate, the liquid portion of the working fluid 6 sealed in each cell 5 is collected by contacting one wide surface side, and the collected liquid does not come into contact with the other wide surface side. It is important that the partition wall 4 be configured to have an inclination and be installed in such a way that this state is maintained (installed substantially vertically).

With this configuration, in the state shown in FIGS. 2 and 3, heat flows unidirectionally from the wide side 1b toward the wide side 1a. Specifically, when the wide side 1b reaches a temperature sufficient to evaporate the working fluid 6 in the cell 5, and the wide side 1a reaches a temperature sufficient to evaporate the working fluid 6 in the cell 5,
In a situation where the temperature is such that the working fluid inside is condensed, the liquid of the working fluid that is in contact with it on the wide side 1b evaporates, and this vapor condenses and liquefies on the wide side 1a. The liquid flows along the inclined lower surface (partition wall 4) and collects the liquid again toward the wide surface side 1b. Therefore, for example, in order to extract heat from the heat medium A existing outside the wide side 1b of the heat exchanger plate to the heat medium B existing outside the wide side 1a, the heat exchanger plate is used as shown in Fig. 2. When used in a state where the partition wall 4 has an upward slope toward the wide side 1a, the heat medium A
When the temperature reaches a predetermined temperature or higher, a heat flow flows into the heat medium B, and when the temperature of the heat medium A is lower than the temperature of the heat medium B, the heat flow does not substantially flow upstream.
Therefore, even if the temperature of the heat medium A varies greatly up and down, only heat above a predetermined temperature can be selected and transferred to the heat medium B. In other words, depending on the situation, heat medium B may be better than heat medium A.
Even if the temperature becomes higher, or if there is a large temperature difference between heat medium A or heat medium B between the top and bottom of the heat transfer plate, or if the temperature fluctuates due to changes over time, there will be no change in temperature from heat medium A to heat medium B. A directional heat flow is generated in which only heat having a predetermined temperature or higher is screened.

FIG. 4 shows an example of constructing a unidirectional heat flow heat exchanger by effectively utilizing the characteristics of the heat exchanger plate of the present invention. That is, the first
~ A plurality of heat transfer plates (the number does not matter as long as they are two or more) as explained in Figure 3 are installed vertically with a predetermined gap between them. Installed with the front and back reversed, the partition walls 4 of adjacent heat exchanger plates are arranged so that the slopes are opposite to each other,
A unidirectional heat exchanger is shown in which one heat exchange fluid A is allowed to flow in a certain gap among the gaps between the heat transfer plates, and the other heat exchange fluid B is made to flow in a gap adjacent to the gap. In the example shown, heat exchanger plates A, C, and E are placed in the state shown in Figure 2 (from wide side 1b to wide side 1b).
The partition wall 4 is inclined upward to the right as it faces toward a), and the adjacent heat transfer plates B and N are installed inside out from the state shown in Fig. 2 (i.e., the wide side 1b is The partition wall 4 is inclined upward to the left when facing toward the wide side 1a), and the heat medium on the high temperature side is installed in the gap between heat exchanger plates B and C, and between the heat exchanger plates D and E. A, these gaps are the gap between adjacent heat exchanger plates A and B, and the gap between heat exchanger plates C and D so that the heat medium B on the low temperature side flows.

In the heat exchanger of the present invention having this configuration, only the heat above a predetermined temperature is screened out, and the heat flows only in the direction from the heat medium A to the heat medium B, so that the temperature of the heat medium changes over time and the heat Even if medium B becomes hotter than heat medium A, only the necessary warm heat is transferred to heat medium B (or only the necessary cold heat is transferred to heat medium A).
) can be taken out.

FIGS. 5 and 6 show building components that effectively utilize the characteristics of the heat exchanger plate of the present invention explained in FIGS. 1 to 3.
For example, external wall structural members of buildings and window materials such as storm shutters are shown, and FIG. 5 shows how they are installed in the winter, and FIG. 6 shows how they are installed in the summer. That is, in FIG. 5, the partition wall 4 of the heat exchanger plate is located outside the room 8.
It is attached to the building so that it slopes upward from the side toward the room 7. With this mounting structure, outdoor heat flows unidirectionally indoors, so in winter, indoor heat is prevented from flowing outdoors, but only when the outdoor temperature becomes hotter due to sunlight etc. can be supplied indoors. On the other hand, in the summer, if the heat exchanger plate is installed in a building so that the partition wall 4 slopes upward from the indoor side 7 toward the outdoor area 8, as shown in Figure 6, While preventing heat from flowing indoors, the heat inside the room is released outdoors when the temperature inside the room becomes high or when the outdoor temperature drops, such as in the early morning.

Figure 7 shows an example of a mounting structure in which the front and back sides are reversed in winter and summer, and the heat exchanger plate 9 is mounted on the vertical axis 1.
It is designed to be attached to a building so that it can rotate around 0.

FIG. 8 shows a structure in which the heat exchanger plate 9 itself is constructed as a shutter, which can be opened and closed by turning it inside out in summer and winter.

As explained above, the heat exchanger plate of the present invention can be used in a unique way by turning it inside out and selectively unidirectionally extracting only the heat above the required temperature. , it exhibits a very unique effect as a component element of thermal equipment.
