Description

[Technical field]

[0001] The present invention relates to a heat exchange member for a board. [Background technology]

[0002] As described in Patent Document 1, a heat exchange member for a panel having a pipe is known as a component of a heat exchanger used for heat exchange in a panel such as a distribution board or switchboard. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-310924 A

[0004] However, such board heat exchange components require pipes of a size according to the heat exchange capacity. Meanwhile, because the structure was such that both ends of multiple pipes were supported by being incorporated into a housing-like member, the size of the housing-like member was changed according to the heat exchange capacity. In other words, if the length of the pipes changes, the size of the housing-like member supporting the pipes also changes. For this reason, there were many types of housing-like members supporting the pipes, and management was a hassle. Summary of the Invention [Problem to be solved by the invention]

[0005] The inventor of the present invention has studied this point diligently and attempted to solve the problem. The problem to be solved by the present invention is to make it possible to avoid the need to change the size of the member supporting the pipe even if the length of the pipe used for heat exchange is changed. [Means for solving the problem]

[0006] In order to solve the above problems, a heat exchange component for a panel is provided which comprises a pipe configured to serve as an air passage and a base to which a plurality of pipes are fixed, wherein the base has a plurality of through holes into which the pipes can be inserted, and each through hole has a regulating portion which regulates the insertion depth of the pipe, and the base is disposed on both one end side and the other end side of the pipe.

[0007] It is also preferable to provide a configuration including a plurality of reservoirs capable of storing adhesive for bonding the pipe and the base.

[0008] It is also preferable that the adhesive stored in an annular reservoir provided along the outer periphery of the pipe be positioned around the entire circumference of the pipe.

[0009] It is also preferable that the bases are provided with engagement portions on their outer peripheries that enable the bases to be connected to each other in a direction perpendicular to the penetrating direction of the through holes.

[0010] It is also preferable that each of the bases is provided with a plurality of engaging portions, and that when the two bases are connected, the orientation in which one of the engaging portions of one base faces the engaging portion of the other base in the penetration direction is reversed to the orientation in which at least one of the other engaging portions of one base faces the engaging portion of the other base in the penetration direction.

[0011] In addition, it is preferable that the two engaging portions provided on one surface of the base are arranged in a direction perpendicular to the penetration direction, and that when the engaging portion provided on the base connected to one end side of the pipe is connected to the engaging portion of the other base, the arrangement in which one of the engaging portions of one base faces the engaging portion of the other base in the penetration direction and the arrangement in which the other engaging portion of one base faces the engaging portion of the other base in the penetration direction are reversed to the arrangement in which one of the engaging portions of one base faces the engaging portion of the other base in the penetration direction and the arrangement in which the other engaging portion of one base faces the engaging portion of the other base in the penetration direction when the engaging portion provided on the base connected to the other end side of the pipe is connected to the engaging portion of the other base.

[0012] It is also preferable that the configuration be such that it is provided with an elastically deformable elastic member, and that in a connection state in which the engagement portion of one base is engaged with the engagement portion of the other base, the restoring force of the elastic member attempting to restore itself when elastically deformed is capable of preventing the engagement between the engagement portion of one base and the engagement portion of the other base from being released. Effect of the Invention

[0013] In the present invention, even if the length of the pipe used for heat exchange is changed, the size of the member supporting the pipe does not need to be changed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The following describes an embodiment of the invention. As can be understood from Figs. 1 to 3, the heat exchanger element 1 for a board according to this embodiment includes a pipe 2 configured to be an air passage, and a base 3 to which the multiple pipes 2 are fixed. The base 3 of the heat exchanger element 1 for a board includes multiple through holes 31 into which the pipes 2 can be inserted, and each through hole 31 includes a regulating portion 32 that regulates the insertion depth of the pipes 2. The bases 3 are disposed on both one and the other ends of the pipes 2. Therefore, since the bases 3 disposed on both one and the other ends of the pipes 2 serve as members that support the pipes 2, the size of the members that support the pipes 2 does not need to be changed even if the length of the pipes 2 used for heat exchange changes.

[0016] Here, a schematic configuration of the panel heat exchanger element 1 will be described. In the panel heat exchanger element 1 of the embodiment, a base 3 is connected to one end of a plurality of pipes 2, and another base 3 is connected to the other end of the pipes 2. In the example shown in Fig. 1 to Fig. 3, the rectangular tubular pipes 2 are arranged in a row and sandwiched between the two bases 3. In this example, the shapes of the bases 3 located at both ends of the pipes 2 are the same, but they do not necessarily have to be the same.

[0017] Each base 3 is provided with a through hole 31, and in the panel heat exchange member 1, air passing through the through hole 31 provided in one base 3 flows into the pipe 2, and air leaving the pipe 2 flows outside the panel heat exchange member 1 through the through hole 31 provided in the other base 3.

[0018] 1 to 3 are rectangular tubular, but may be round tubular, however, the number of pipes 2 can be reduced if the pipes are rectangular tubular.

[0019] It is preferable that the pipe 2 and the base 3 are firmly fixed, but it is also important to ensure ease of fixing the pipe 2 and the base 3. In this embodiment, in order to enable the pipe 2 to be inserted into the base 3 by an appropriate length, the through hole 31 of the pipe 2 is configured so that the pipe 2 does not penetrate the base 3. In order to achieve this configuration, the cross section of the through hole 31 cut perpendicular to the penetration direction is not uniform (see FIG. 4).

[0020] When the pipe 2 is inserted into the through hole 31 shown in Fig. 4, the end face 22 of the pipe 2 comes into contact with the base 3, thereby restricting the pipe 2 from being inserted any deeper (see Figs. 4 and 5). In other words, the through hole 31 is configured to include a restricting portion 32 that restricts the insertion depth of the pipe 2.

[0021] 4 is configured by forming a surface extending in a direction perpendicular to the penetration direction of the through hole 31, other configurations may be adopted for the restricting portion 32, such as forming the restricting portion 32 by a surface extending obliquely to the penetration direction. However, if the restricting portion 32 is configured to have a surface extending in a direction perpendicular to the penetration direction of the through hole 31, the restricting portion 32 can abut against the end face 22 of the pipe 2 to restrict the insertion depth of the pipe 2, so that the insertion depth of the pipe 2 can be determined without being affected by the thickness of the pipe 2.

[0022] 4 to 6, the restricting portion 32 is provided to come into contact with the end face 22 of the pipe 2. In this example, the restricting portion 32 is configured to be able to come into contact with the end face 22 over the entire circumference of the pipe 2. The restricting portion 32 does not have to be configured to be able to come into contact with the end face 22 of the pipe 2 over the entire circumference. In the example shown in Fig. 7, the restricting portion 32 is configured to come into discontinuous contact with the end face 22 of the pipe 2.

[0023] One method of regulating the insertion depth of the pipe 2 may be to provide a protrusion or the like on the pipe 2 that can hook 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 pipe 2.

[0024] Furthermore, if the cross section of a portion of the through hole 31 is made the same as the cross section of the pipe 2, the pipe 2 and the base 3 can be fixed simply by inserting the pipe 2 into the through hole 31. Even without the above configuration, if the base 3 is configured to be able to come into contact with the pipe 2 at multiple points, the pipe 2 and the base 3 can be fixed simply by inserting the pipe 2 into the through hole 31. However, since it is not always possible to manufacture all of the pipe 2 and base 3 with the expected dimensions, it is preferable to use an adhesive 91 or the like to connect the pipe 2 and the base 3 (see FIG. 5).

[0025] In the embodiment, a recess 51 is provided on the outer periphery of the pipe 2 when the pipe 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 pipe 2 and the base 3, so that the adhesive 91 can be prevented from diffusing when the pipe 2 and the base 3 are bonded together. This makes the bonding process easier. Also, it is easier to ensure the adhesive strength.

[0026] Any type of reservoir may be used to store the adhesive 91 that bonds the pipe 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 pipes 2 are inserted.

[0027] As can be understood from these descriptions, it is preferable to have a configuration including a plurality of reservoirs capable of storing adhesive 91 for bonding pipe 2 and base 3 together.

[0028] Furthermore, in order to prevent air or liquid from flowing in through a gap that may occur between the pipe 2 and the base 3, it is preferable that the adhesive 91 is provided around the entire circumference of the pipe 2. For this reason, it is preferable that a reservoir such as the recess 51 is provided around the entire circumference of the pipe 2. When the adhesive 91 is provided around the entire circumference of the pipe 2, the adhesive 91 becomes annular.

[0029] As can be understood from these descriptions, it is preferable that the adhesive 91 stored in an annular reservoir provided along the outer periphery of the pipe 2 be positioned around the entire circumference of the pipe 2 .

[0030] Incidentally, it is preferable that the board heat exchanger 1 is configured so that it can be connected. If multiple board heat exchanger 1 are combined, the capacity can be adjusted. For example, if the board heat exchanger 1 is connected in a direction perpendicular to the penetration direction of the through holes 31, the number of air inlets can be increased (see Figures 8 and 9).

[0031] In the embodiment, the base 3 is provided with an engagement portion 34 so that the board heat exchange members 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 Figs. 1 and 2, the engagement 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 Figs. 1 and 2, the engagement portion 34 is provided on four faces of the base 3 which is configured in a roughly rectangular parallelepiped shape, and other board heat exchange members 1 can be connected to the four sides of the board heat exchange member 1.

[0032] Even when the board heat exchanger member 1 can be connected in a direction perpendicular to the penetration direction of the through hole 31, it is not necessary to connect the board heat exchanger member 1 to other board heat exchanger members 1 from all four sides. Therefore, the board heat exchanger member 1 does not have to be configured to have engagement parts 34 on all four sides. For example, the board heat exchanger member 1 may be configured to have engagement parts 34 only on one side, or only on two or three sides of the board heat exchanger member 1. In any case, it is preferable to configure the board heat exchanger member 1 so that it can be connected in a state where the engagement parts 34 provided on the outer periphery of one base 3 and the engagement parts 34 provided on the outer periphery of the other base 3 are engaged with each other.

[0033] As can be understood from these descriptions, it is preferable to have an engagement portion 34 on the outer periphery of the base 3 that enables the bases 3 to be connected to each other in a direction perpendicular to the penetrating direction of the through hole 31.

[0034] In the examples shown in Figures 1, 8 to 11, board heat exchange members 1 arranged next to each other are engaged with two engaging portions 34 extending from one board heat exchange member 1 and two engaging portions 34 extending from the other board heat exchange member 1. The two engaging portions 34 extending from one board heat exchange member 1 are configured to abut in opposite directions against the engaging portions 34 extending from the other board heat exchange member 1. This makes it possible to prevent the board heat exchange members 1 from being separated from each other.

[0035] In addition, in the examples shown in Figures 1, 8 to 11, when the two bases 3 are connected, the "orientation in which one of the engagement portions 34 of one base 3 faces the engagement portion 34 of the other base 3 in the penetration direction" and the "orientation in which the other engagement portion 34 of one base 3 faces the engagement portion 34 of the other base 3 in the penetration direction" are reversed.

[0036] In addition, if this configuration is expressed using the relationships of up, down, front, back, left and right shown in FIG. 1, the "penetration direction" is the up and down direction, but the "direction in which one of the engagement parts 34 of one base 3 faces the engagement part 34 of the other base 3 in the penetration direction" and the "direction in which the other engagement part 34 of one base 3 faces the engagement part 34 of the other base 3 in the penetration direction" are the up and down directions. In other words, one of the two engagement parts 34 engages so as to be located on the lower side of the board heat exchange member 1 to be combined, and the other engages so as to be located on the upper side of the board heat exchange member 1 to be combined. Therefore, it is possible to prevent the board heat exchange members 1 from being separated from each other. Even when adopting such a mode, the number of engagement parts 34 that contact the adjacent board heat exchange member 1 does not need to be limited to two, and may be three or more.

[0037] As can be understood from these descriptions, it is preferable that each of the bases 3 is provided with a plurality of engagement portions 34, and that when the two bases 3 are connected, the orientation in which one of the engagement portions 34 of one base 3 faces the engagement portion 34 of the other base 3 in the penetration direction is reversed to the orientation in which at least one of the other engagement portions 34 of one base 3 faces the engagement portion 34 of the other base 3 in the penetration direction.

[0038] Furthermore, when the panel heat exchanger member 1 shown in Figure 1 is connected in the left-right or front-back direction using the engaging portions 34, in either case the "orientation in which one of the engaging portions 34 of one base 3 faces the engaging portion 34 of the other base 3 in the penetration direction" and the "orientation in which the other engaging portion 34 of one base 3 faces the engaging portion 34 of the other base 3 in the penetration direction" are reversed upside down.

[0039] In addition, the base 3 is provided with an elastic member 41, which can prevent the engagement parts 34 from being separated when the board heat exchange members 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 engagement part 34 of one base 3 from being disengaged from the engagement part 34 of the other base 3.

[0040] 10 and 11, the engaging portion 34 provided on one base 3 and the engaging portion 34 provided on the other base 3 each have a protruding portion 34a that protrudes in opposite directions, and the protruding portions 34a engage with each other so as to mesh with each other. An elastic member 41 is configured to apply a force to the engaging portion 34 in the horizontal direction in order to maintain the protruding portions 34a in the meshed state.

[0041] 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 engagement between the engagement portion 34 of one base 3 and the engagement portion 34 of the other base 3 from being released 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 engagement portion 34 of one base 3 is engaged with the engagement portion 34 of the other base 3. It is preferable to use a packing as the elastic member 41.

[0042] The engaging portion 34 does not have to have such a configuration. For example, it may have an engaging portion 34 that protrudes laterally and an engaging portion 34 that is formed by a recess (see Figs. 12 and 13). In this example, since the engaging portion 34 extending laterally can be accommodated in the recessed engaging portion 34 (see Figs. 14 and 15), when the board heat exchanger elements 1 are connected to each other, the overall size can be reduced. Note that in the example shown in Figs. 12 and 13, the engaging portions 34 are provided on only two sides, and it is only possible to use the engaging portions 34 to connect in a direction perpendicular to the penetration direction of the through holes 31 from only two sides.

[0043] In the example of the engaging portion 34 shown in FIG. 12, when connected, the protrusion 34b is caught in the front-rear direction, thereby preventing movement in the front-rear direction, and the laterally extending engaging portion 34 is contained in the concave engaging portion 34, thereby preventing movement in the left-right direction.

[0044] In this example, the upper base 3 and the lower base 3 shown in FIG. 12 both have engagement parts 34 lined up in the left-right direction on the front side, but when these engagement parts 34 are used to connect with other board heat exchange members 1, the left engagement part 34 of the upper base 3 is a part that will be located below the engagement part 34 of the other board heat exchange member 1 with which it engages, and the left engagement part 34 of the lower base 3 is also a part that will be located below the engagement part 34 of the other board heat exchange member 1 with which it engages. In addition, the right engagement part 34 of the upper base 3 is a part that will be located above the engagement part 34 of the other board heat exchange member 1 with which it engages, and the right engagement part 34 of the lower base 3 is a part that will be located above the engagement part 34 of the other board heat exchange member 1 with which it engages. For this reason, it is difficult to separate the connected board heat exchange members 1 by moving them vertically.

[0045] However, by moving the board heat exchanger 1 in a rotating manner, it is relatively easy to separate the board heat exchanger members 1 from each other. In other words, in the configuration shown in Fig. 12, the connected state of the board heat exchanger members 1 cannot be released by moving the board heat exchanger members 1 linearly, but can be released by moving the board heat exchanger members 1 in a rotating manner.

[0046] In the example shown in FIG. 1, the two engaging 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 engaging portions 34 of one base 3 faces the engaging portion 34 of the other base 3 in the penetration direction" and "the orientation in which the other engaging portion 34 of one base 3 faces the engaging portion 34 of the other base 3 in the penetration direction" when the engaging portion 34 provided on the base 3 connected to one end side of the pipe 2 (e.g., the base 3 located on the lower side) is connected to the engaging portion 34 of the other base 3 is similar to the arrangement of "the orientation in which one of the engaging portions 34 of one base 3 faces the engaging portion 34 of the other base 3 in the penetration direction" and "the orientation in which the other engaging portion 34 of one base 3 faces the engaging portion 34 of the other base 3 in the penetration direction" when the engaging portion 34 provided on the base 3 connected to the other end side of the pipe 2 (e.g., the base 3 located on the upper side) is connected to the engaging portion 34 of the other base 3. Therefore, by rotating the board heat exchange elements 1, the board heat exchange elements 1 can be easily separated from each other.

[0047] Since the above-mentioned "arrangement" may be difficult to understand, a further explanation will be given with reference to the drawings. In FIG. 16, the "direction in which one of the engaging portions 34 faces the engaging portion 34 of the other base 3 in the penetration direction" is indicated by a thick arrow. In FIG. 16, the engaging portion 34 located on the left front side of the base 3 located below the pipe 2 engages with the engaging portion 34 of the other base 3 so that it is located on the upper side, and the engaging portion 34 located on the right front side of the base 3 located below the pipe 2 engages with the engaging portion 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 engaging portions 34 faces the engaging portion 34 of the other base 3 in the penetration direction" is arranged in the order of "up, down" from left to right.

[0048] 16, the engaging portion 34 located on the left front side of the base 3 located above the pipe 2 engages with the engaging portion 34 of the other base 3 so that it is located above, and the engaging portion 34 located on the right front side of the base 3 located above the pipe 2 engages with the engaging portion 34 of the other base 3 so that it is located below. In other words, in the upper base 3, the "direction in which one of the engaging portions 34 faces the 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 engaging portions 34 of the upper base 3 and the engaging portions 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 engaging portions 34 faces the engaging portion 34 of the other base 3 in the penetration direction."

[0049] On the other hand, to make it difficult to come off even when rotating, the arrangement may be reversed. In other words, the two engaging parts 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 engaging parts 34 of one base 3 faces the engaging part 34 of the other base 3 in the penetration direction when the engaging part 34 provided on the base 3 connected to one end of the pipe 2 is connected to the engaging part 34 of the other base 3" and "the orientation in which the other engaging part 34 of one base 3 faces the engaging part 34 of the other base 3 in the penetration direction" is reversed to the arrangement of "the orientation in which one of the engaging parts 34 of one base 3 faces the engaging part 34 of the other base 3 in the penetration direction when the engaging part 34 provided on the base 3 connected to the other end of the pipe 2 is connected to the engaging part 34 of the other base 3" and "the orientation in which the other engaging part 34 of one base 3 faces the engaging part 34 of the other base 3 in the penetration direction"". Even in this case, if the heat exchanger component 1 is configured to tolerate some degree of deformation, it will be possible to attach and detach the heat exchanger components 1. For example, if the pipes 2 and base 3 are made of resin, it will be possible to configure the heat exchanger component 1 to tolerate some degree of deformation.

[0050] For example, if the engaging portions 34 of the upper base 3 are arranged in the order of "up, down" from left to right in the "orientation in which one of the engaging portions 34 faces the engaging portion 34 of the other base 3 in the penetration direction," then the engaging portions 34 of the lower base 3 can be arranged in the order of "down, up" from left to right in the "orientation in which one of the engaging portions 34 faces the engaging portion 34 of the other base 3 in the penetration direction."

[0051] The heat exchanger 1 for a panel described so far has a configuration in which the base 3 is in contact with both ends of one pipe 2, but this configuration is not necessarily required. For example, the heat exchanger 1 for a panel as shown in Figs. 17 and 18 has the base 3 in contact with only one end of one pipe 2. The pipes 2 are not arranged so that their end faces 22 face each other. The pipes 2 in contact with one base 3 and the pipes 2 in contact with the other base 3 are arranged alternately to form a bundle. In order to properly use the heat exchanger 1 for a panel, it is necessary to cover the surroundings with a plate material so that the air circulating inside the panel 8 does not mix with the air sent in large quantities from outside the panel 8 for heat exchange.

[0052] In this example, a connecting member 61 is attached so that the pipes 2 come into contact with each other, and the pipe 2 abutting against one base 3 and the pipe 2 abutting against the other base 3 are appropriately positioned. In the example shown in Fig. 19, the connecting member 61 has a plurality of first fitting portions 62 that are inserted between the pipes 2 abutting against one base 3, and a plurality of second fitting portions 63 that are inserted between the pipes 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 face 22 of the pipe 2, so that the spacing between the bases 3 can be appropriately secured.

[0053] Here, an example of a board 8 equipped with a board heat exchanger member 1 will be described. As can be seen from Fig. 20, the board heat exchanger member 1 is usually attached to the housing of the board 8. The board heat exchanger member 1 is mainly used to cool the air inside the board 8. This is because, although the inside of the board 8 heats up easily, it is undesirable for the electric and electronic devices provided inside the board 8 to heat up.

[0054] In the example shown in Fig. 20, air inside the board 8 is passed through pipe 2 of the board heat exchanger 1, and air is sent from outside the board 8 around the pipe 2, thereby cooling the air passing through the inside of the pipe 2. A blower 71 for passing air through the inside of the pipe 2 and a blower 72 for sending external air toward the board heat exchanger 1 may be operated as needed, or may be operated all the time. The air sent from the blower 72 toward the board heat exchanger 1 is sent out of the board 8 after passing around the pipe 2.

[0055] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be modified in various ways. [Explanation of symbols]
