Description

  The present invention relates to a heat radiating pipe covering mechanism used for a ceiling panel in which sound absorbing holes are formed.

As this type of heat radiating pipe covering mechanism, the one shown in Patent Document 1 is conventionally known. Such a heat radiating pipe covering mechanism is used for laying a heat radiating pipe for supplying a cold / hot fluid on a ceiling panel. It means mechanism. The ceiling radiation panel using this conventional heat radiating pipe covering mechanism will be described with reference to FIG. 5, and FIG. 6 shows a conventional heat radiating pipe covering mechanism.
In this conventional ceiling radiant panel, a resin heat radiating pipe 1 made of a flammable material is laid on a panel body a. The heat radiating pipe 1 is formed by alternately repeating a straight portion 1a and a U-turn portion 1b. It is meandering. And although the said linear part 1a is covered with the heat sink 2, this heat sink 2 was provided in the recessed part 2a according to the curvature of the surface of the heat radiating pipe 1 as shown in FIG. 6, and both sides of this recessed part 2a. And a flat plate portion 2b.

And while wrapping the linear part 1a of the heat radiating pipe 1 previously laid in the said recessed part 2a, the flat plate part 2b is closely_contact | adhered to the panel main body a, and the heat sink 2 is being fixed to the panel main body a. However, the U-turn portion 1b has a bare structure.
For example, when a cold / hot fluid is supplied to the heat radiating pipe 1 of the panel body a as described above, the cold / hot fluid flows from one side of the heat radiating pipe 1 and flows out to the other. Heat is released to the panel body a, and the radiant heat of the panel body a cools and cools the room.
Japanese Utility Model Publication No. 5-19828

  The heat radiating pipe covering mechanism configured as described above is configured such that the heat radiating pipe 1 directly contacts the main body panel a. In other words, as is clear from FIG. 6, the heat radiating plate 2 covers the heat radiating pipe 1 at the upper side and the side of the heat radiating pipe 1, but at the lower side, the heat radiating pipe 1 is connected to the panel body a. It is in an exposed state. However, the ceiling panel actually requires a sound absorption hole. If the heat sink 2 is provided in the panel body a having the sound absorption hole, for example, when a fire breaks out from the room, the flame in the room is removed from the sound absorption hole. It will burn to the heat radiating pipe 1, which is also against the Fire Service Act.

  Therefore, in order to prevent the heat radiating pipe 1 from burning, it is also conceivable to lay the heat radiating pipe 1 while avoiding the sound absorbing hole so that the heat radiating pipe 1 does not overlap the sound absorbing hole. However, in a ceiling radiating panel, it is usual that the sound absorbing holes are formed evenly with respect to the panel body a for reasons such as appearance and sound absorbing effect. Therefore, it is practically impossible to form the sound absorbing holes according to the shape and laying position of the heat radiating pipe 1 or to lay the heat radiating pipe 1 so as to avoid all the sound absorbing holes. there were. And since there existed such a problem, it was not possible to renovate the existing ceiling panel in which the sound absorption hole was formed, and to install a ceiling radiation panel, for example.

In addition, it is theoretically possible to form the sound absorbing holes while avoiding the position where the heat radiating pipe 1 is laid at the stage of manufacturing the panel body a. However, in reality, not all buildings have air conditioning units installed on the back of the ceiling, and there are also buildings that place importance on sound absorption, and several types of ceiling panels with different sound absorption holes are produced. However, there is a problem that the manufacturing cost is increased.
Further, when a large number of sound absorbing holes are formed in the panel main body a, even if the heat radiating pipe 1 can be laid while avoiding all the sound absorbing holes, the heat radiating pipes 1 are evenly arranged with respect to the panel main body a. This causes a problem that the radiation efficiency becomes extremely low because the length of contact with the panel body “a” cannot be reduced or the length of contact with the panel main body “a” is shortened.

  This invention can achieve a high fire-proof performance while radiating pipes can be installed without lowering the radiation efficiency and not depending on the position of the sound absorption holes, even in a ceiling panel in which sound absorption holes are formed. It is another object of the present invention to provide a heat radiating pipe covering mechanism that can maintain a sound absorbing effect.

The present invention is for a ceiling panel penetrating a sound absorption hole, and presupposes a heat radiation pipe covering mechanism for covering a heat radiation pipe meandering by alternately repeating a straight portion and a U-turn portion.
The first invention covers the entire surface of the heat radiating pipe with a metal covering member, and when the heat radiating pipe covered with the metal covering member is laid on the ceiling panel, the straight line portion of the heat radiating pipe located adjacent to each other. There is a feature in that a space is formed between portions of the corresponding metal covering members, and the sound absorbing holes can be exposed in these spaces.
2nd invention has the characteristics in the point which made the contact surface with the ceiling panel in a metal covering member the flat surface.
According to a third aspect of the present invention, the metal covering member is fixed to the heat equalizing plate made of a metal flat plate and one surface of the heat equalizing plate, and the fixing plate covers the heat radiating pipe between the heat equalizing plate. It is characterized in that
The fourth invention is characterized in that the fixing plate is divided into portions corresponding to the linear portion or the U-turn portion of the heat radiating pipe.
The fifth invention is characterized in that the cross-sectional shape of the heat radiating pipe is deformed and the heat radiating pipe is brought into close contact with the inner periphery of the metal covering member.

According to the first invention, since the entire circumference of the heat radiating pipe is covered with the metal covering member, the heat radiating pipe is not exposed to the sound absorbing hole, and high fire prevention performance can be realized. Therefore, even if a heat radiating pipe is arranged on the sound absorption hole formed in the ceiling panel, there is no problem in fire prevention performance, and it is possible to lay the heat radiating pipe freely on the ceiling panel without special consideration of the Fire Service Act etc. it can. In this way, if the heat radiating pipes can be laid freely, the heat radiating pipes can be arranged at even intervals with respect to the ceiling panel, so that there is no unevenness in the radiant heat to the ceiling panel and no uneven temperature in the room. .
Further, since it is not necessary to provide the heat radiating pipe avoiding the sound absorbing holes, even if the ceiling panel has a large number of sound absorbing holes, the contact area between the heat radiating pipe covering mechanism and the ceiling panel can be ensured as much as necessary. . Therefore, when laying the heat radiating pipe, for example, the manufacturing cost can be reduced by using a standard ceiling panel, or the existing ceiling panel can be remodeled into a ceiling radiation panel.
In addition, since a predetermined interval is provided between portions corresponding to the straight portions of the heat radiating pipes arranged adjacent to each other, the sound absorbing hole can be penetrated through a surface corresponding to the interval. Therefore, the sound absorbing effect can be reliably maintained while realizing high fire resistance as described above.
In addition, since the metal covering member is made of metal, it has a high thermal conductivity, and the heat of the cold / hot fluid flowing through the heat radiating pipe can be efficiently transmitted to the ceiling panel.

According to the second invention, since the contact area with the ceiling panel is increased by the flat surface of the metal covering member, the heat of the heat radiating pipe is efficiently transmitted to the ceiling panel.
According to the third aspect of the present invention, after the heat equalizing plate is fixed to the ceiling panel in advance and the heat radiating pipe is laid thereon, the heat radiating pipe can be covered with the fixing plate. Therefore, the laying position of the heat radiating pipe, in other words, the meandering pattern of the heat radiating pipe can be determined in advance, and the workability is improved such that the heat radiating pipes can be easily and evenly arranged. Moreover, as long as it has a heat equalizing plate, a fixed plate, and a heat radiating pipe, all can be installed on site.
According to the fourth invention, since only the fixing plate is divided, the heat radiating pipe is not exposed to the ceiling panel. Therefore, workability can be further improved while maintaining high fire resistance.
According to the fifth invention, since the cross-sectional shape of the heat radiating pipe is deformed and the heat radiating pipe is brought into close contact with the inner periphery of the metal covering member, the thermal conductivity can be improved.

A first embodiment of the present invention will be described with reference to FIGS. It should be noted that the same constituent elements as those in the prior art will be described with the same reference numerals.
In the ceiling panel b shown in FIG. 1, a large number of sound absorbing holes r are formed and a resin-made heat radiating pipe 1 is laid. The heat radiating pipe 1 laid on the ceiling panel b is meandering as a whole by alternately repeating the straight portions 1a and the U-turn portions 1b. The straight portion 1 a and the U-turn portion 1 b are covered with a metal fixing plate 3. This structure will be described in detail with reference to FIGS.
As shown in FIG. 2, the fixed plate 3 includes an arch-shaped recess 3 a that matches the curvature of the surface of the heat radiating pipe 1, and flat plate portions 3 b provided on both sides of the concave portion 3 a, and the heat radiating pipe 1 is It is made to cover with the recessed part 3a.

Then, below the fixed plate 3 and the heat radiating pipe 1, there is provided a single heat plate 4 made of a metal flat plate, and a flat plate portion 3 b of the fixed plate 3 on one surface of the heat plate 4. The metal cover member K covers the entire surface of the heat radiating pipe 1. The flat plate portion 3b and the soaking plate 4 may be fixed by any method such as welding or bonding. Either the fixing plate 3 or the soaking plate 4 is made a permanent magnet, and its magnetic force is fixed. You may make it fix both. Particularly when the ceiling panel b is made of metal, the soaking plate 4 and the ceiling panel b and the soaking plate 4 and the fixing plate 3 can be easily fixed by using the soaking plate 4 as a permanent magnet. can do.
As described above, in the first embodiment, the entire circumference of the heat radiating pipe 1 is completely covered with the fixed plate 3 and the heat equalizing plate 4, but the fixed plate 3 and the heat equalizing plate 4 are combined. A metal covering member K is formed.
Further, as is clear from FIG. 1, the fixing plate 3 in the first embodiment is divided into a straight portion corresponding to the straight portion 1a of the heat radiating pipe 1 and a U-turn portion corresponding to the U-turn portion 1b. Each is formed separately. However, the heat equalizing plate 4 is not divided for each straight portion 1a or U-turn portion 1b of the heat radiating pipe 1, but is configured as a single meandering member.
In the metal covering member K, a portion corresponding to the straight portion of the fixing plate 3 is indicated as Ka, and a portion corresponding to the U-turn portion of the fixing plate 3 is indicated as Kb. 2 is a cross-sectional view showing the portion Ka, and FIG. 3 is a cross-sectional view showing the portion Kb.

Then, the other surface of the soaking plate 4 is fixed to the ceiling panel b, and the heat radiating pipe 1 is laid thereon, and the heat radiating pipe 1 is further covered with the fixing plate 3. At this time, as shown in FIG. 1, a plurality of portions Ka corresponding to the straight portions 1a in the metal covering member K are arranged in parallel, but correspond to the straight portions 1a arranged adjacent to each other. A predetermined interval S is formed between the portions Ka. 1 to 3, the sound absorbing hole r formed in the ceiling panel b is exposed at the interval S, but the sound absorbing hole r is located below the metal covering member K. In some cases, the back side of the ceiling panel b is not exposed.
For example, when a cold / hot fluid is supplied to the heat radiating pipe 1 laid as described above, the cold / hot fluid flows in from one side of the heat radiating pipe 1 and flows out to the other. Is transmitted to the ceiling panel b through the metal covering member K, and the room is cooled and heated by the radiant heat of the ceiling panel b.

According to the heat radiating pipe covering mechanism of the first embodiment, since the entire circumference of the heat radiating pipe 1 is covered with the metal covering member, the heat radiating pipe 1 is not exposed to the sound absorbing hole r and has high fire prevention performance. Can be realized. Therefore, even if the heat radiating pipes 1 are arranged on the sound absorbing holes r formed in the ceiling panel b, there is no problem in fire prevention performance, and the heat radiating pipes 1 can be laid freely without special consideration of the fire fighting law or the like. . Thus, if the heat radiating pipe 1 can be laid freely, the heat radiating pipes 1 can be arranged at equal intervals with respect to the ceiling panel b, and the radiant heat to the ceiling panel b is uneven, or the temperature is uneven in the room. Does not occur.
Further, since it is not necessary to provide the heat radiating pipe 1 while avoiding the sound absorbing holes r, the heat radiating pipe covering mechanism and the ceiling panel b are in contact with each other even if the ceiling panel b has many sound absorbing holes r as shown in FIG. As much area as necessary can be secured. Therefore, when laying the heat radiating pipe 1, for example, a manufacturing cost can be reduced by using a standard ceiling panel, or an existing ceiling panel can be reformed to be a ceiling radiation panel.

In addition, a predetermined interval S is provided between the portions Ka corresponding to the linear portions 1a arranged adjacent to each other, and the sound absorbing holes r are exposed in the interval S, so that the high fire resistance as described above can be achieved. While realizing, the sound absorption effect can be reliably maintained.
In addition, since the metal covering member K is made of metal, it has high thermal conductivity, and can efficiently transfer the heat of the cold / hot fluid flowing through the heat radiating pipe 1 to the ceiling panel b.
Further, after the heat equalizing plate 4 is fixed to the ceiling panel b in advance and the heat radiating pipe 1 is laid thereon, the heat radiating pipe 1 can be covered with the fixing plate 3. Therefore, the laying position of the heat radiating pipe 1, in other words, the meandering pattern of the heat radiating pipe 1 can be determined in advance, and the workability is improved such that the heat radiating pipes 1 can be easily and evenly arranged. In addition, as long as the heat equalizing plate 4, the fixed plate 3, and the heat radiating pipe 1 are provided, all can be installed on site. Moreover, since only the fixing plate 3 is divided, the heat radiating pipe 1 is not exposed to the ceiling panel b, and the workability can be further improved while maintaining high fire resistance.

In addition, in 1st Embodiment, although the cross-sectional shape of the heat radiating pipe 1 is circular, the shape of the heat radiating pipe 1 is not specifically limited, If it is a relationship covered with the metal covering member K, what is it? Such a shape may be used. However, if the cross-sectional shape of the heat radiating pipe is deformed and the area where the heat equalizing plate 4 and the heat radiating pipe are in contact with each other is increased, the thermal conductivity with respect to the ceiling panel b can be improved.
That is, as apparent from FIGS. 2 and 3, since the cross-sectional shape of the heat radiating pipe 1 is circular, a gap is formed between the heat radiating pipe 1 and the heat equalizing plate 4. Therefore, the contact area between the heat radiating pipe 1 and the soaking plate 4 is reduced, and the thermal conductivity from the radiating pipe 1 to the soaking plate 4 is reduced accordingly.
Therefore, if the cross section of the heat radiating pipe is processed to be flat and tightly attached to the heat equalizing plate 4, in other words, if the heat radiating pipe is closely attached to the inner periphery of the metal covering member K, the thermal conductivity is improved. Can be made.
Such deformation of the heat radiating pipe can be performed by a known technique, so that it can be easily manufactured and processed, and if the pipe connection portion is made circular in cross-section at the time of deformation, a conventional pipe joint Can be used as is.

Next, a second embodiment of the present invention will be described with reference to FIG. The heat radiating pipe covering mechanism in the second embodiment is different from the first embodiment only in the configuration of the metal covering member K, and the other configurations and operations are the same as those in the first embodiment. Therefore, the same components as those in the first embodiment are described with the same reference numerals, and detailed descriptions thereof are omitted.
The heat radiating pipe covering mechanism shown in FIG. 4 is a metal covering member comprising a heat radiating pipe 1 laid on the ceiling panel b and made to meander by repeating the straight portions 1a and U-turn portions 1b alternately, and a tube. K.
The metal covering member K has a through hole 5 having a diameter substantially equal to the outer diameter of the heat radiating pipe 1 formed therein, and the heat radiating pipe 1 is fitted in close contact with the through hole 5. . In other words, the heat radiating pipe 1 is covered with the metal covering member K exactly.
Moreover, although the outer periphery shape of the metal covering member K is made into circular arc shape, the flat surface 6 is formed in the downward direction.

And the flat surface 6 of the metal covering member K is fixed to the ceiling panel b in the state where the heat radiating pipe 1 is covered with the metal covering member K. Then, in the metal covering member K, an interval S is formed between portions corresponding to the straight portion 1a of the heat radiating pipe 1 as in the first embodiment.
If the cold / hot fluid is supplied to the heat radiating pipe 1 laid as described above, the cold / hot fluid will heat and cool the room provided with the ceiling panel b and the ceiling panel b as in the first embodiment. It is.
According to the heat radiating pipe covering mechanism of the second embodiment, since the entire circumference of the heat radiating pipe 1 is covered with the metal covering member K as in the first embodiment, the heat radiating pipe 1 is exposed to the sound absorbing hole r. High fire prevention performance can be realized without taking out. Therefore, even if the heat radiating pipes 1 are arranged on the sound absorbing holes r formed in the ceiling panel b, there is no problem in fire prevention performance, and the heat radiating pipes 1 can be laid freely without special consideration of the fire fighting law or the like. . Thus, if the heat radiating pipe 1 can be laid freely, the heat radiating pipes 1 can be arranged at equal intervals with respect to the ceiling panel b, and the radiant heat to the ceiling panel b is uneven, or the temperature is uneven in the room. Does not occur.
Further, since the heat radiating pipe 1 does not need to be provided so as to avoid the sound absorbing holes r, only the contact area between the heat radiating pipe covering mechanism and the ceiling panel b is required even for the ceiling panel b in which many sound absorbing holes r are formed. Can be secured. Therefore, when laying the heat radiating pipe 1, for example, a manufacturing cost can be reduced by using a standard ceiling panel, or an existing ceiling panel can be reformed to be a ceiling radiation panel.

In addition, a predetermined interval is provided between the portions corresponding to the straight portions 1a of the heat radiating pipes 1 arranged adjacent to each other, and the sound absorbing holes r are exposed in this interval. The sound absorbing effect can be reliably maintained while realizing the characteristics.
In addition, since the metal covering member K is made of metal, it has high thermal conductivity, and can efficiently transfer the heat of the cold / hot fluid flowing through the heat radiating pipe 1 to the ceiling panel b.

Moreover, in 2nd Embodiment, since the contact surface with the ceiling panel b in the metal covering member K was made into the flat surface 6, the heat | fever of the cold / hot fluid which flows through the thermal radiation pipe 1 passes through the metal covering member K. It is transmitted firmly to the ceiling panel b.
In addition, the metal covering member K in the second embodiment may be formed separately for each linear portion 1a or U-turn portion 1b of the heat radiating pipe 1, or may be formed as one member without being divided. Absent. In any case, any configuration may be used as long as the space S is formed between the portions corresponding to the straight portion 1a of the heat radiating pipe 1.

  Moreover, the cross-sectional shape of the heat radiating pipe 1 is not particularly limited, and any shape may be used as long as the entire circumference is covered by the metal covering member K. However, if the inner peripheral surface of the through-hole 5 is made flat on the flat surface 6 side and the heat radiating pipe has a cross-sectional rectangle or semicircular shape, the heat radiating pipe and the metal covering member K come into contact with each other on the flat surface 6 side. A part can be enlarged and the thermal conductivity with respect to the ceiling panel b can be improved.
