Description

[Technical field]

[0001] The present invention relates to a heat exchange unit for a panel. [Background technology]

[0002] Panel heat exchange units are known as components of heat exchangers used for heat exchange in panels such as distribution boards and switchboards. Panel heat exchange units are of the pipe type (one of the ventilation passages is configured in a cylindrical shape) as disclosed in Patent Document 1, and the plate type as disclosed in Patent Document 2. The choice of whether to adopt a panel heat exchange unit of the pipe type or the plate type has been made according to the required cooling capacity. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-310924 A [Patent Document 2] Japanese Patent Application Publication No. 61-175781

[0004] However, the heat exchanger components for panel heat exchange units are made for pipe type and plate type only, and no heat exchanger components that can be used for both pipe type and plate type have been developed. For this reason, there are many types of panel heat exchange units, and management is a hassle. Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors of the present invention have made extensive research into this issue and have attempted to solve the problem. The problem that the present invention aims to solve is to reduce the effort required for managing a panel heat exchange unit. [Means for solving the problem]

[0006] In order to solve the above problem, a heat exchange unit for a panel is provided which includes a plurality of rectangular heat exchange elements each having a first ventilation passage and a second ventilation passage, wherein two or more of the heat exchange elements have an opening on a first surface which is connected to the first ventilation passage and an opening on a second surface which is located opposite the first surface, an opening on a third surface which extends perpendicular to the first surface and is connected to the second ventilation passage, and an opening on a fourth surface which is located opposite the third surface which is connected to the second ventilation passage, and the openings on the first surface which are connected to the first ventilation passage and the openings on the second surface which are connected to the second ventilation passage are arranged alternately in the direction in which the fifth surface and the sixth surface are aligned, and the heat exchange unit for a panel is capable of changing the ventilation path by changing the connection mode between the heat exchange elements.

[0007] Furthermore, it is preferable that any two of the multiple heat exchange members be capable of forming an air passage that can exhibit a heat exchange function by combining the first air passage of one heat exchange member with the second air passage of the other heat exchange member and combining the second air passage of one heat exchange member with the first air passage of the other heat exchange member in a connected manner, and that a ventilation path that can exhibit a heat exchange function be formed by combining the first air passage of one heat exchange member with the first air passage of the other heat exchange member and combining the second air passage of one heat exchange member with the second air passage of the other heat exchange member in a connected manner.

[0008] In addition, it is preferable that any two of the multiple heat exchange members are connected so that the first surface of one heat exchange member faces the first surface of the other heat exchange member to form an air passage capable of performing heat exchange function.

[0009] It is also preferable that the heat exchange member is provided with a connecting engagement portion for engaging with another heat exchange member when the heat exchange member is connected to the heat exchange member.

[0010] In addition, it is preferable that any two of the multiple heat exchange members are provided with a claw portion that serves as a connecting engagement portion and an elastic member that can be elastically deformed, and that the configuration is capable of preventing the engagement between the claw portion of one heat exchange member and the claw portion of the other heat exchange member from being released due to the restoring force of the elastic member that has been elastically deformed in a connection state in which the claw portion of one heat exchange member and the claw portion of the other heat exchange member are engaged with each other.

[0011] In addition, it is preferable that any two of the multiple heat exchange members have multiple connecting engagement portions, and that when connected, the orientation in which one of the connecting engagement portions of one heat exchange member faces the connecting engagement portion of the other heat exchange member is opposite to the orientation in which at least one of the other connecting engagement portions of one heat exchange member faces the connecting engagement portion of the other heat exchange member. Effect of the Invention

[0012] The present invention makes it possible to reduce the effort required for managing the panel heat exchange unit. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. A panel heat exchange unit 1 of the embodiment includes a plurality of rectangular parallelepiped heat exchange members 2 each having a first ventilation passage 10a and a second ventilation passage 10b. In this board heat exchange unit 1, two or more of the heat exchange members 2 are provided on the first surface 11 with an opening 11a connected to the first ventilation passage 10a and an opening 11b connected to the second ventilation passage 10b, on the second surface 12 located opposite the first surface 11 with an opening 12a connected to the first ventilation passage 10a, on the third surface 13 extending perpendicularly to the first surface 11 with an opening 13b connected to the second ventilation passage 10b, on the fourth surface 14 located opposite the third surface 13 with an opening 14b connected to the second ventilation passage 10b, and the openings 11a connected to the first ventilation passage 10a and the openings 11b connected to the second ventilation passage 10b provided on the first surface 11 are alternately arranged in the direction in which the fifth surface 15 and the sixth surface 16 are aligned. In addition, the ventilation path can be changed by changing the connection mode between the heat exchange members 2. This makes it possible to reduce the effort required for managing the board heat exchange unit 1.

[0015] Here, the heat exchange member 2, which is a component of the board heat exchange unit 1, will be described. The heat exchange member 2 has a first air passage 10a and a second air passage 10b. The board heat exchange unit 1 is configured to adjust the temperature of the target air by utilizing the temperature difference between the air passing through the first air passage 10a and the air passing through the second air passage 10b. More specifically, the board heat exchange unit 1 is configured to adjust the temperature of the target air by utilizing heat transfer via a heat transfer member that separates the first air passage 10a and the second air passage 10b.

[0016] As can be understood from FIGS. 1 to 3, the heat exchange member 2 of the embodiment is a rectangular parallelepiped, and four of the six faces are used for air to flow in and out of the first ventilation passage 10a or the second ventilation passage 10b, but two faces are not used for air to flow in and out of the first ventilation passage 10a or the second ventilation passage 10b. The first ventilation passage 10a is configured so that air flows in and out through the first surface 11 and the second surface 12 located opposite the first surface 11 (see FIG. 4). In this example, the first ventilation passage 10a extends straight from the first surface 11 to the second surface 12, but may be configured to meander between the first surface 11 and the second surface 12. In any case, air flows in and out of the first ventilation passage 10a only through the first surface 11 and the second surface 12, and not through the third surface 13 to the sixth surface 16. More specifically, air flows in and out of first ventilation passage 10a only through opening 11a provided in first surface 11 and opening 12a provided in second surface 12.

[0017] On the other hand, air flows in and out of second ventilation passage 10b through two or more of first surface 11, third surface 13 extending perpendicular to first surface 11, and fourth surface 14 located opposite third surface 13. For this reason, first surface 11 has opening 11b connected to second ventilation passage 10b, third surface 13 has opening 13b connected to second ventilation passage 10b, and fourth surface 14 has opening 14b connected to second ventilation passage 10b.

[0018] Therefore, the first surface 11 has both the opening 11a connected to the first ventilation passage 10a and the opening 11b connected to the second surface 12. In addition, in the first surface 11 of the heat exchange member 2 shown in Figs. 3 and 4, the opening 11a connected to the first ventilation passage 10a and the opening 11b connected to the second surface 12 are arranged so as to be alternately positioned. More specifically, in the first surface 11 of the heat exchange member 2 shown in Figs. 3 and 4, the opening 11a connected to the first ventilation passage 10a and the opening 11b connected to the second ventilation passage 10b are arranged alternately in the direction in which the fifth surface 15 and the sixth surface 16 are arranged. Note that only the first surface 11 has both the opening connected to the first ventilation passage 10a and the opening connected to the second surface 12 on the same surface.

[0019] The second surface 12 has an opening 12a connected to the first ventilation passage 10a, but does not have an opening connected to the second ventilation passage 10b. The third surface 13 has an opening 13b connected to the second ventilation passage 10b, but does not have an opening connected to the first ventilation passage 10a. The fourth surface 14, like the third surface 13, has an opening 14b connected to the second ventilation passage 10b, but does not have an opening connected to the first ventilation passage 10a.

[0020] The panel heat exchange unit 1 includes a plurality of heat exchange members, and the heat exchange members 2 having the above-mentioned configuration can be used in combination, or the heat exchange member 2 having the above-mentioned configuration can be used in combination with a heat exchange member having a different configuration. In either case, in order to enable appropriate combination, it is preferable that the heat exchange member is provided with a connecting engagement portion 28 for engaging with another heat exchange member when connecting the heat exchange member to the other heat exchange member.

[0021] Here, an example of using two heat exchange members 2 having the above-mentioned configuration in combination will be described. In the example shown in FIG. 5, the first surface 11 of one heat exchange member 2 and the first surface 11 of the other heat exchange member 2 are connected to face each other (see FIG. 6), and the first ventilation passage 10a of one heat exchange member 2 and the second ventilation passage 10b of the other heat exchange member 2 are combined to be connected. Also, the second ventilation passage 10b of one heat exchange member 2 and the first ventilation passage 10a of the other heat exchange member 2 are combined to be connected. In this case, it can be used as a plate-type board heat exchange unit 1. In addition, the heat exchange member 2 has recesses and protrusions that become the connecting engagement parts 28 so that such combination can be performed appropriately.

[0022] Even when the first surface 11 of one heat exchange member 2 and the first surface 11 of the other heat exchange member 2 are connected to face each other, the combination is not limited to the example shown in FIG. 5. In the example shown in FIG. 7, the first surface 11 of one heat exchange member 2 and the first surface 11 of the other heat exchange member 2 are connected to face each other, but the first ventilation passage 10a of one heat exchange member 2 and the first ventilation passage 10a of the other heat exchange member 2 are combined to be connected. In addition, the second ventilation passage 10b of one heat exchange member 2 and the second ventilation passage 10b of the other heat exchange member 2 are also combined to be connected. In this case, it can be used as a pipe-type panel heat exchange unit 1. The heat exchange member 2 is provided with a connecting engagement portion 28 so that such a combination can be appropriately performed.

[0023] As can be understood from these descriptions, it is preferable that any two of the multiple heat exchange members 2 of the panel heat exchange unit 1 be capable of forming an air passage capable of performing heat exchange function when the first surface 11 of one heat exchange member 2 and the first surface 11 of the other heat exchange member 2 are connected so as to face each other.

[0024] Furthermore, it is preferable that any two of the multiple heat exchange members 2 of the panel heat exchange unit 1 are "capable of forming an air passage that can exhibit a heat exchange function by combining the first air passage 10a of one heat exchange member 2 with the second air passage 10b of the other heat exchange member 2, and by combining the second air passage 10b of one heat exchange member 2 with the first air passage 10a of the other heat exchange member 2 in a connected manner," and that "the first air passage 10a of one heat exchange member 2 is capable of forming an air passage that can exhibit a heat exchange function by combining the first air passage 10a of one heat exchange member 2 with the first air passage 10a of the other heat exchange member 2, and by combining the second air passage 10b of one heat exchange member 2 with the second air passage 10b of the other heat exchange member 2 in a connected manner."

[0025] In addition, an example in which the heat exchange member 2 having the above-mentioned configuration is combined with a heat exchange member having another configuration will be described. In the example shown in FIG. 8, three heat exchange members are arranged vertically (see FIG. 9). The heat exchange members 2 at both ends are the heat exchange members 2 having the above-mentioned configuration, but the heat exchange member 2A located in the middle is configured to play a role of connecting the heat exchange members 2 located above and below, and the surface located in the upper part thereof has an opening connected to the first ventilation passage 10a of the first surface 11 of the heat exchange member 2 located above, and also has an opening connected to the second ventilation passage 10b. In addition, the surface located in the lower part thereof has an opening connected to the first ventilation passage 10a of the first surface 11 of the heat exchange member 2 located below, and also has an opening connected to the second ventilation passage 10b. In this case, it can be used as a plate-type board heat exchange unit 1.

[0026] In the examples so far, the heat exchange members 2 are combined in the direction in which the first surface 11 and the second surface 12 face each other, but the heat exchange members 2 may be combined so as to be perpendicular to the direction in which the first surface 11 and the second surface 12 face each other. In the example shown in Fig. 10, only four heat exchange members 2 having the above-mentioned configuration are prepared, and each heat exchange member 2 is combined so as to be adjacent to another heat exchange member 2 in the direction in which the first surface 11 and the second surface 12 face each other and in the direction perpendicular to the direction in which the first surface 11 and the second surface 12 face each other. In this case, it can be used as a pipe-type heat exchange unit 1 for a panel.

[0027] Here, the use of the panel heat exchange unit 1 having the configuration shown in Fig. 10 will be described. For example, as shown in Fig. 11, the panel heat exchange unit 1 is placed inside the housing of the panel 8. To adjust the temperature of the air inside the housing of the panel 8, air is introduced from the outside of the housing of the panel 8 and heat exchange is performed. After heat exchange is completed, the air introduced from the outside of the housing of the panel 8 is discharged to the outside of the housing of the panel 8. The panel heat exchange unit 1 is mainly used to cool the air inside the panel 8.

[0028] 11, air inside the board 8 is passed through the heat exchange member 2 of the board heat exchange unit 1, and air is sent from outside the board 8 around the heat exchange member 2, thereby cooling the air passing through the inside of the heat exchange member 2. A blower 71 for passing air through the inside of the heat exchange member 2 and a blower 72 for sending external air toward the board heat exchange unit 1 may be operated as needed, or may be operated all the time. The air sent from the blower 72 toward the board heat exchange unit 1 is sent out of the board 8 after passing around the heat exchange member 2.

[0029] Air introduced from outside the housing of the panel 8 is introduced into the second ventilation passage 10b, and as can be seen from Figures 12 and 13, the second ventilation passages 10b of the heat exchange members 2 arranged vertically are combined so as to be connected to each other, and the second ventilation passages 10b of the heat exchange members 2 arranged horizontally are combined so as to be connected to each other. However, if left as is, the air for heat exchange brought from the outside will mix with the air inside the housing of the panel 8, so the inlet and outlet of the ventilation path using the second ventilation passage 10b in the panel heat exchange unit 1 are limited by, for example, covering a part of it with a blocking member 88 (see Figure 14).

[0030] On the other hand, as can be seen from Figs. 12 and 15, the first ventilation passages 10a of the heat exchange members 2 arranged vertically are combined so as to connect to each other, but the first ventilation passages 10a of the heat exchange members 2 arranged horizontally are combined so as not to connect to each other. For this reason, the air inside the housing of the board 8 moves through a ventilation path extending in the vertical direction (see Fig. 16). In the example shown in Fig. 11, the air inside the housing of the board 8 moves through the first ventilation passages 10a from bottom to top, but it may move in the opposite direction. However, in this case, it is preferable that the direction of movement through the second ventilation passages 10b is also reversed from the example shown in Fig. 11. This is because heat exchange is more likely to be performed efficiently in this way.

[0031] Not limited to the example shown in Fig. 10, but also in the example shown in Fig. 7 or other cases, if a pipe type is adopted, the same configuration may be used. However, if a plate type is adopted, the configuration will not be the same as that of the pipe type, so an example in which a plate type is adopted will be described below.

[0032] For example, as shown in FIG. 17, the board heat exchange unit 1 is disposed outside the housing of the board 8. In order to adjust the temperature of the air inside the housing of the board 8, a blower 71 is used to guide the air inside the housing of the board 8 to the outside of the housing of the board 8, and heat exchange is performed in the board heat exchange unit 1. The air introduced into the board heat exchange unit 1 from inside the housing of the board 8 is returned to the inside of the housing of the board 8 after heat exchange is completed. Meanwhile, in order to adjust the temperature of the air inside the housing of the board 8, a blower 72 is used to introduce air into the board heat exchange unit 1 from the outside of the housing of the board 8, and heat exchange is performed. The air introduced into the board heat exchange unit 1 from the outside of the housing of the board 8 is discharged from the board heat exchange unit 1 to the outside of the housing of the board 8 after heat exchange is completed.

[0033] For example, assume that the board heat exchange unit 1 shown in FIG. 5 is adopted. In the following example, air introduced from outside the housing of the board 8 is introduced from below the board heat exchange unit 1 and discharged from the upper side. In this example, the air introduced from outside the housing of the board 8 is introduced into the first ventilation passage 10a of the heat exchange member 2 on the lower side, but this first ventilation passage 10a is connected to the second ventilation passage 10b of the heat exchange member 2 located on the upper side (see FIGS. 18 and 19), so the air used for heat exchange is discharged from the second ventilation passage 10b of the heat exchange member 2 located on the upper side. However, if this is left as it is, the air for heat exchange brought from the outside will mix with the internal air of the housing of the board 8, so the inlet and outlet of the ventilation path using the second ventilation passage 10b in the board heat exchange unit 1 are limited by covering a part with a blocking member 88, for example (see FIG. 20).

[0034] Meanwhile, air inside the housing of the board 8 is introduced from the upper side of the board heat exchange unit 1 and discharged from the lower side. In this example, air inside the housing of the board 8 is introduced into the first ventilation passage 10a of the heat exchange member 2 on the upper side, but this first ventilation passage 10a is connected to the second ventilation passage 10b of the heat exchange member 2 located on the lower side (see Figs. 18 and 21), so the air that has been heat exchanged is discharged from the second ventilation passage 10b of the heat exchange member 2 located on the lower side (see Fig. 22). In this example, the ventilation direction may also be reversed.

[0035] Up to this point, an example has been described in which the heat exchange members 2 are assembled so as to be in close contact with each other, but other configurations are also possible. For example, a board heat exchange unit 1 is provided with a base 3 on which the heat exchange members 2 can be attached with a gap therebetween. In Figs. 23 and 24, a configuration is provided in which separate bases 3 are connected to both ends of one heat exchange member 2. In the example shown in Figs. 23 and 24, the bases 3 are connected to the first surface 11 and the second surface 12 of the heat exchange member 2.

[0036] Here, a schematic configuration of a board heat exchange unit 1 having a base 3 will be described. In the board heat exchange unit 1 of the embodiment, a base 3 is connected to one end side of a plurality of heat exchange members 2, and another base 3 is connected to the other end side of the heat exchange members 2. In the example shown in Fig. 23 to Fig. 25, rectangular parallelepiped heat exchange members 2 are sandwiched between two bases 3 while being lined up in a row. In this example, the shapes of the bases 3 located at both ends of the heat exchange members 2 are the same, but they do not necessarily have to be the same.

[0037] Each base 3 is provided with a through hole 31, and in the panel heat exchange unit 1, air passing through the through hole 31 provided in one base 3 flows into the heat exchange member 2, and air leaving the heat exchange member 2 flows outside the panel heat exchange unit 1 through the through hole 31 provided in the other base 3.

[0038] It is preferable that the heat exchange member 2 and the base 3 are firmly fixed, but it is also important to ensure ease of fixing the heat exchange member 2 and the base 3. In this embodiment, in order to enable the heat exchange member 2 to be inserted into the base 3 by an appropriate length, the through hole 31 of the heat exchange member 2 is configured so that the heat exchange member 2 does not penetrate the base 3. In order to achieve this configuration, the through hole 31 is configured so that the cross section cut perpendicular to the penetration direction is not uniform (see FIG. 26).

[0039] 26, when the heat exchange member 2 is inserted, the end face 22 of the heat exchange member 2 comes into contact with the base 3, thereby restricting the heat exchange member 2 from being inserted any deeper (see FIGS. 26 and 27). In other words, the through hole 31 is configured to include a restriction portion 32 that restricts the insertion depth of the heat exchange member 2.

[0040] 26 is configured by forming a surface extending in a direction perpendicular to the penetration direction of the through hole 31, but other configurations may be adopted for the restriction portion 32, such as forming the restriction portion 32 by a surface extending obliquely to the penetration direction. However, if the surface extending in a direction perpendicular to the penetration direction of the through hole 31 is configured to be the restriction portion 32, the insertion depth of the heat exchange member 2 can be restricted by the restriction portion 32 abutting against the end face 22 of the heat exchange member 2, so that the insertion depth of the heat exchange member 2 can be determined without being affected by the thickness of the heat exchange member 2.

[0041] 26 to 28 include a restricting portion 32 that contacts the end face 22 of the heat exchange member 2. In this example, the restricting portion 32 is configured so as to be able to contact the end face 22 over the entire circumference of the heat exchange member 2. The restricting portion 32 does not have to be configured so as to be able to contact the end face 22 of the heat exchange member 2 over the entire circumference. In the example shown in Fig. 29, the restricting portion 32 is configured so as to contact the end face 22 of the heat exchange member 2 discontinuously.

[0042] One method of regulating the insertion depth of the heat exchange member 2 may be to provide a protrusion or the like on the heat exchange member 2 that can be hooked onto the base 3. However, taking safety into consideration, it is preferable to provide a regulating portion 32 in the through hole 31 rather than providing a protrusion or the like on the heat exchange member 2.

[0043] Furthermore, by making the cross section of a portion of the through hole 31 similar to the cross section of the heat exchange member 2, it is possible to fix the heat exchange member 2 to the base 3 simply by inserting the heat exchange member 2 into the through hole 31. Even without the above configuration, it is possible to configure the base 3 so that it can come into contact with the heat exchange member 2 at multiple points, so that the heat exchange member 2 and the base 3 can be fixed simply by inserting the heat exchange member 2 into the through hole 31. However, since it is not always possible to manufacture all of the heat exchange member 2 and the base 3 with the expected dimensions, it is preferable to bond the heat exchange member 2 to the base 3 using an adhesive 91 or the like (see FIG. 27).

[0044] In the embodiment, a recess 51 is provided on the outer periphery of the heat exchange member 2 when the heat exchange member 2 is inserted into the through hole 31. This recess 51 can be used as a reservoir that can store the adhesive 91 while in contact with both the heat exchange member 2 and the base 3, so that the adhesive 91 can be prevented from diffusing when bonding the heat exchange member 2 and the base 3. This makes the bonding process easier. Also, it is easier to ensure the adhesive strength.

[0045] Any type of reservoir may be used to store the adhesive 91 that bonds the heat exchange member 2 and the base 3. However, if multiple reservoirs for storing the adhesive 91 are provided, the area in which the adhesive 91 is stored can be reduced. This is expected to reduce the amount of adhesive 91 used. It is more preferable to provide a configuration in which the number of reservoirs is equal to the number of through holes 31 into which the heat exchange members 2 are inserted.

[0046] As can be understood from these descriptions, it is preferable to have a configuration including a plurality of reservoirs capable of storing the adhesive 91 for bonding the heat exchange member 2 and the base 3 together.

[0047] Moreover, in order to prevent air or liquid from flowing in through a gap that may occur between the heat exchange member 2 and the base 3, it is preferable that the adhesive 91 is provided around the entire circumference of the heat exchange member 2. For this reason, it is preferable that a reservoir portion such as the recessed portion 51 is provided around the entire circumference of the heat exchange member 2. When the adhesive 91 is provided around the entire circumference of the heat exchange member 2, the adhesive 91 becomes annular.

[0048] As can be understood from these descriptions, it is preferable that the adhesive 91 stored in the annular reservoir provided along the outer periphery of the heat exchange element 2 be positioned over the entire periphery of the heat exchange element 2 .

[0049] Incidentally, it is preferable that the panel heat exchange units 1 are configured so that they can be connected. If multiple panel heat exchange units 1 are combined, the capacity can be adjusted. For example, if the panel heat exchange units 1 are connected in a direction perpendicular to the penetration direction of the through holes 31, the number of air inlets can be increased (see Figures 30 and 31).

[0050] In the embodiment, the base 3 is provided with a base engaging portion 34 so that the board heat exchange units 1 can be connected to each other in a direction perpendicular to the penetration direction of the through holes 31. In the example shown in Fig. 23 and Fig. 24, the base engaging portion 34 is configured to extend in a direction perpendicular to the penetration direction of the through holes 31. Also, in the example shown in Fig. 23 and Fig. 24, the base engaging portion 34 is provided on four faces of the base 3 configured in a roughly rectangular parallelepiped shape, and other board heat exchange units 1 can be connected to the four sides of the board heat exchange unit 1.

[0051] Even if the board heat exchange unit 1 can be connected in a direction perpendicular to the through-hole 31, it is not necessary to connect the board heat exchange unit 1 to other board heat exchange units 1 from all four sides. Therefore, the board heat exchange unit 1 does not have to be configured to have the base engagement portion 34 on all four sides. For example, the board heat exchange unit 1 may be configured to have the base engagement portion 34 only on one side, or may be configured to have the base engagement portion 34 only on two sides or only on three sides. In any case, it is preferable to configure the board heat exchange unit 1 so that it can be connected in a state where the base engagement portion 34 provided on the outer periphery of one base 3 and the base engagement portion 34 provided on the outer periphery of the other base 3 are engaged with each other.

[0052] As can be understood from these descriptions, it is preferable to have a configuration in which the outer periphery of the base 3 is provided with a base engaging portion 34 that enables the bases 3 to be connected to each other in a direction perpendicular to the penetrating direction of the through hole 31.

[0053] In the examples shown in Figures 23, 30 to 33, the board heat exchange units 1 arranged next to each other are engaged with two base engagement parts 34 extending from one board heat exchange unit 1 and two base engagement parts 34 extending from the other board heat exchange unit 1. The two base engagement parts 34 extending from one board heat exchange unit 1 are configured to abut in opposite directions against the base engagement parts 34 extending from the other board heat exchange unit 1. This makes it possible to prevent the board heat exchange units 1 from being separated from each other.

[0054] In addition, in the examples shown in Figures 23 and 30 to 33, when the two bases 3 are connected, the "orientation in which one of the base engagement portions 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction" and the "orientation in which the other base engagement portion 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction" are reversed.

[0055] If this configuration is expressed using the relationships of up, down, front, back, left and right shown in FIG. 23, the "penetration direction" is the up and down direction, but the "direction in which one of the base engaging parts 34 of one base 3 faces the base engaging part 34 of the other base 3 in the penetration direction" and the "direction in which the other base engaging part 34 of one base 3 faces the base engaging part 34 of the other base 3 in the penetration direction" are the up and down directions. In other words, one of the two base engaging parts 34 engages so as to be located on the lower side of the combined board heat exchange unit 1, and the other engages so as to be located on the upper side of the combined board heat exchange unit 1. Therefore, it is possible to prevent the board heat exchange units 1 from being separated from each other. Even when adopting such a mode, the number of base engaging parts 34 that contact the adjacent board heat exchange unit 1 does not need to be limited to two, and may be three or more.

[0056] As can be understood from these descriptions, it is preferable that each of the bases 3 is provided with a plurality of base engagement portions 34, and that when the two bases 3 are connected, the orientation in which one of the base engagement portions 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction is opposite to the orientation in which at least one of the other base engagement portions 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction.

[0057] Furthermore, when the panel heat exchange unit 1 shown in Figure 23 is connected in the left-right or front-to-back directions using the base engagement portion 34, in either case, the "orientation in which one of the base engagement portions 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction" and the "orientation in which the other base engagement portion 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction" are reversed upside down.

[0058] In addition, the base 3 is provided with an elastic member 41, which can prevent the base engagement parts 34 from being separated when the panel heat exchange units 1 are connected to each other. This is because the restoring force of the elastically deformed elastic member 41 attempts to restore its original shape, preventing the base engagement part 34 of one base 3 from being disengaged from the base engagement part 34 of the other base 3.

[0059] In the examples shown in Figures 32 and 33, the base engaging portion 34 provided on one base 3 and the base engaging portion 34 provided on the other base 3 each have a protruding portion 34a that protrudes in opposite directions up and down, and the protruding portions 34a engage with each other so as to mesh with each other. In other words, they form claw portions that can hook onto each other. The elastic member 41 is configured to apply a force in the horizontal direction to the base engaging portion 34 in order to maintain the protruding portions 34a in the meshed state.

[0060] As can be understood from these descriptions, it is preferable to have an elastically deformable elastic member 41, and to have a configuration capable of preventing the disengagement of the base engaging portion 34 of one base 3 and the base engaging portion 34 of the other base 3 due to a restoring force of the elastically deformed elastic member 41 attempting to restore its original shape in a connected state in which the base engaging portion 34 of one base 3 is engaged with the base engaging portion 34 of the other base 3. It is preferable to use a packing as the elastic member 41.

[0061] The base engaging portion 34 does not have to have such a configuration. For example, the base engaging portion 34 may be provided with a base engaging portion 34 that protrudes laterally and a base engaging portion 34 that is formed by a recess (see Figs. 34 and 35). In this example, the base engaging portion 34 that extends laterally can be accommodated in the recessed base engaging portion 34 (see Figs. 36 and 37), so that when the board heat exchange units 1 are connected to each other, the overall size can be reduced. In the example shown in Figs. 34 and 35, the base engaging portions 34 are provided on only two sides, and it is possible to connect the board heat exchange units 1 in a direction perpendicular to the penetration direction of the through-hole 31 using the base engaging portions 34 only from two sides.

[0062] In the example shown in Figure 36, when connected, the protrusion 34b catches in the front-to-rear direction, thereby preventing movement in the front-to-rear direction, and the laterally extending base engaging portion 34 is contained in the concave base engaging portion 34, thereby preventing movement in the left-to-right direction.

[0063] In this example, the upper base 3 and the lower base 3 shown in FIG. 34 have the base engagement parts 34 aligned in the left-right direction on the front side, but when the base engagement parts 34 are used to connect with other board heat exchange units 1, the base engagement part 34 on the left side of the upper base 3 is a part that will be located below the base engagement part 34 of the other board heat exchange unit 1 to be engaged, and the base engagement part 34 on the left side of the lower base 3 is also a part that will be located below the base engagement part 34 of the other board heat exchange unit 1 to be engaged. In addition, the base engagement part 34 on the right side of the upper base 3 is a part that will be located above the base engagement part 34 of the other board heat exchange unit 1 to be engaged, and the base engagement part 34 on the right side of the lower base 3 is a part that will be located above the base engagement part 34 of the other board heat exchange unit 1 to be engaged. For this reason, it is difficult to separate the connected board heat exchange units 1 by moving them vertically.

[0064] However, if the panel heat exchange units 1 are moved in a rotating manner, the panel heat exchange units 1 can be separated relatively easily. In other words, in the configuration shown in Fig. 34, the connected state of the panel heat exchange units 1 cannot be released by moving the panel heat exchange units 1 linearly, but can be released by moving the panel heat exchange units 1 in a rotating manner.

[0065] In the example shown in FIG. 23 , the two base engaging portions 34 provided on one surface of the base 3 are aligned in a direction perpendicular to the penetration direction, and the orientation of the base engaging portion 34 is such that, in a state in which the base engaging portion 34 provided on the base 3 connected to one end side of the heat exchange member 2 (e.g., the base 3 located on the lower side) is connected to the base engaging portion 34 of the other base 3, “one of the base engaging portions 34 of one base 3 faces the base engaging portion 34 of the other base 3 in the penetration direction” and “the other base engaging portion 34 of one base 3 faces the base engaging portion 34 of the other base 3 in the penetration direction” is “the other base engaging portion 34 of the one base 3 faces the base engaging portion 34 of the other base 3 in the penetration direction”. The arrangement of "the orientation in which one of the base engaging portions 34 of one base 3 faces the base engaging portion 34 of the other base 3 in the penetration direction" is similar to the arrangement of "the orientation in which one of the base engaging portions 34 of one base 3 faces the base engaging portion 34 of the other base 3 in the penetration direction" and "the orientation in which the other base engaging portion 34 of one base 3 faces the base engaging portion 34 of the other base 3 in the penetration direction" when the base engaging portion 34 of the base 3 (e.g. the upper base 3) connected to the other end side of the heat exchange member 2 is connected to the base engaging portion 34 of the other base 3. Therefore, the board heat exchange units 1 can be easily separated from each other by rotating them.

[0066] Since the above-mentioned "arrangement" may be difficult to understand, a further explanation will be given with reference to the drawings. In FIG. 38, the "direction in which one of the base engagement parts 34 faces the base engagement part 34 of the other base 3 in the penetration direction" is indicated by a thick arrow. In FIG. 38, the base engagement part 34 located on the left front side of the base 3 located below the heat exchange member 2 engages with the base engagement part 34 of the other base 3 so that it is located on the upper side, and the base engagement part 34 located on the right front side of the base 3 located below the heat exchange member 2 engages with the base engagement part 34 of the other base 3 so that it is located on the lower side. In other words, in the lower base 3, the "direction in which one of the base engagement parts 34 faces the base engagement part 34 of the other base 3 in the penetration direction" is arranged in the order of "up, down" from left to right.

[0067] 38, the base engaging portion 34 located on the left front side of the base 3 located on the upper side of the heat exchange member 2 engages with the base engaging portion 34 of the other base 3 so that it is located on the upper side, and the base engaging portion 34 located on the right front side of the base 3 located on the upper side of the heat exchange member 2 engages with the base engaging portion 34 of the other base 3 so that it is located on the lower side. In other words, in the upper base 3, the "direction in which one of the base engaging portions 34 faces the base engaging portion 34 of the other base 3 in the penetration direction" is arranged in the order of "up, down" from left to right. Therefore, the base engaging portion 34 of the upper base 3 and the base engaging portion 34 of the lower base 3 are both arranged in the order of "up, down" from left to right in the "direction in which one of the base engaging portions 34 faces the base engaging portion 34 of the other base 3 in the penetration direction."

[0068] On the other hand, to make it difficult for the connector to come off even when it is rotated, the arrangement can be reversed. In other words, the two base engagement portions 34 provided on one surface of the base 3 are arranged in a direction perpendicular to the penetration direction, and the arrangement of "the orientation in which one of the base engagement portions 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction when the base engagement portion 34 provided on the base 3 connected to one end side of the heat exchange member 2 is connected to the base engagement portion 34 of the other base 3" and "the orientation in which the other base engagement portion 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction" is reversed to the arrangement of "the orientation in which one of the base engagement portions 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction when the base engagement portion 34 provided on the base 3 connected to the other end side of the heat exchange member 2 is connected to the base engagement portion 34 of the other base 3" and "the orientation in which the other base engagement portion 34 of one base 3 faces the base engagement portion 34 of the other base 3 in the penetration direction"." Even in this case, if the panel heat exchange unit 1 is configured to tolerate some deformation, it is possible to attach and detach the panel heat exchange units 1. For example, if the heat exchange member 2 and the base 3 are made of resin, it is possible to configure the panel heat exchange unit 1 to tolerate some deformation.

[0069] For example, if the base engagement portions 34 of the upper base 3 are arranged in the order of "up, down" from left to right in terms of "the direction in which one of the base engagement portions 34 faces the base engagement portion 34 of the other base 3 in the penetration direction," then the base engagement portions 34 of the lower base 3 can be arranged in the order of "down, up" from left to right in terms of "the direction in which one of the base engagement portions 34 faces the base engagement portion 34 of the other base 3 in the penetration direction."

[0070] A configuration such as the base engagement portion 34 can also be used for the connecting engagement portion 28. For example, any two of the multiple heat exchange members 2 can be configured to include claw portions that serve as the connecting engagement portion 28 and an elastically deformable elastic member 41, and can be configured to suppress the release of the engagement between the claw portions of one heat exchange member 2 and the claw portions of the other heat exchange member 2 due to a restoring force of the elastically deformed elastic member 41 attempting to restore in a connected state in which the claw portions of one heat exchange member 2 and the claw portions of the other heat exchange member 2 are engaged. In this case, it is possible to make the connection between the heat exchange members 2 difficult to come off.

[0071] Furthermore, any two of the multiple heat exchange members 2 may be provided with multiple connecting engagement portions 28, and may be configured such that, in a connected state, the orientation in which one of the connecting engagement portions 28 of one heat exchange member 2 faces the connecting engagement portion 28 of the other heat exchange member 2 is opposite to the orientation in which at least one of the other connecting engagement portions 28 of one heat exchange member 2 faces the connecting engagement portion 28 of the other heat exchange member 2.

[0072] The board heat exchange unit 1 with the base 3 described above has a configuration in which the base 3 is in contact with both ends of one heat exchange member 2, but this configuration is not necessarily required. For example, the board heat exchange unit 1 as understood from the figures 39 and 40 has the base 3 in contact with only one end of one heat exchange member 2. In addition, the heat exchange members 2 are not arranged so that their end faces 22 face each other. The heat exchange members 2 in contact with one base 3 and the heat exchange members 2 in contact with the other base 3 are arranged alternately to form a unit. In order to make it possible to use the board heat exchange unit 1 appropriately, it is necessary to cover the surroundings with a plate material so that the air circulating inside the board 8 and the air sent in large quantities from outside the board 8 for heat exchange do not mix.

[0073] In this example, a connecting member 61 is attached so that the heat exchange members 2 come into contact with each other, and the heat exchange members 2 abutting against one base 3 and the heat exchange members 2 abutting against the other base 3 are appropriately positioned. In the example shown in Fig. 41, the connecting member 61 has a plurality of first fitting portions 62 that are inserted between the heat exchange members 2 abutting against one base 3, and has a plurality of second fitting portions 63 that are inserted between the heat exchange members 2 abutting against the other base 3. In addition, the first fitting portions 62 and the second fitting portions 63 are each configured to be able to come into contact with the end faces 22 of the heat exchange members 2, so that the spacing of the bases 3 can be appropriately secured.
