Description

[Detailed description of the invention] Industrial application field This invention relates to an insulating wall panel used as a structural member of the wall of a house, particularly an insulating wall panel that also functions as a condenser for a room cooler. .

Conventional technology and its problems When a room cooler is conventionally installed in a house, its heat dissipation condenser (condenser) is usually installed outdoors. For this reason, not only is there a need for a dedicated outdoor installation location for the condenser, but the condenser is of a forced air cooling type, causing problems such as being a source of noise.

In view of these problems, this idea was developed so that the condenser part of the room cooler installed in the house can be formed using the wall surface of the building frame. The present invention aims to provide a heat insulating wall panel.

Means to Solve the Problems This invention is a wall panel constituting the wall of a house, in which a condensing refrigerant pipe connected to the refrigerant circuit of the room cooler is installed on the outer surface of the heat insulating board. In addition to being provided in a buried state, a heat sink is used as an exterior surface plate on the outdoor side of the panel, and the heat sink is overlaid on the outer surface of the heat insulating substrate with the inner surface brought into close contact with the refrigerant pipe. The subject matter is a heat insulating wall panel for a house that is integrally bonded and has the function of a cooling condenser.

The heat insulating substrate is preferably formed of heat-adhesive expanded polystyrene.

Embodiments The configuration of this invention will be further explained with reference to illustrated embodiments as follows.

Fig. 1 schematically shows a room in a house equipped with a room cooler.One side wall of the room R facing the outdoors is formed of the heat insulating wall panel P according to this invention, and the room An indoor unit including an evaporator of the cooler is attached to the upper part of an arbitrary inner wall inside R.

As shown in FIG. 2, the above-mentioned heat-insulating wall panel P has a condensing panel connected to the refrigerant circuit of the room cooler on one side of the heat-insulating substrate 1 made of foamed synthetic resin, etc., especially on the outer surface facing outdoors. A refrigerant pipe 2 is placed in a buried state. In addition, a heat dissipation plate 3 as an exterior surface plate of the panel P is integrally bonded to the outer surface of the heat insulating substrate 1 in a manner such that the inner surface is brought into close contact with the refrigerant pipe 2, and furthermore, the heat dissipation plate 3 is integrally bonded to the outer surface of the heat insulating substrate 1 in a manner that the inner surface is brought into close contact with the refrigerant pipe 2. A back plate 4 is integrally bonded to the inner surface thereof in a superimposed manner.

The material of the heat insulating substrate 1 is not particularly limited, and may be made of foamed polyurethane, particle board, etc., but thermally adhesive foamed polystyrene ( Preferably, the material is made of styrene maleic anhydride copolymer).

The refrigerant pipe 2 is generally made of copper, aluminum, etc. In the illustrated embodiment, it is a single metal pipe having a meandering bent portion 2a, and both ends of the pipe are connected to one side wall of the panel P. It projects from the top, and the projecting portion can be connected to the evaporator of the indoor unit A via a compressor or the like.

The heat sink 3 faces outdoors and serves as a radiating surface for hot air. Therefore, metal plates with good thermal conductivity, such as aluminum plates, colored steel plates, galvanized steel plates, etc., are preferably used, but synthetic resin plates may also be used. The back plate 4 may be made of the same material as the heat dissipation plate described above, or if it is directly exposed inside the room R, a wooden board or the like whose surface has been subjected to a necessary decorative treatment may be used.

The above-described heat-insulating wall panel P according to this invention can be advantageously manufactured by the following method by using heat-adhesive foamed polystyrene for the heat-insulating substrate 1.

That is, first, as shown in FIG. 3, a pipe fitting groove 5 corresponding to the shape of the refrigerant pipe 2 is formed on one side of the heat insulating substrate 1. This fitting groove 5 may be created at the same time using a mold when the heat insulating substrate 1 is manufactured. Next, the refrigerant pipe 2, which has been formed into the desired shape in advance, is fitted into the pipe fitting groove 5, and then the heat dissipation plate 3 and the back plate 4 are superimposed on both sides of the heat insulating board 1, as shown in FIG. The laminated state is put into a hot cold press machine and hot pressure is applied from both sides.

Here, the heat-pressure operation conditions include a temperature of 120 to 200°C (particularly preferably 120 to 140°C), a time of 0.1 to 10 minutes (preferably 1 to 5 minutes), and a pressure of 0.1 to 10 Kg/cm ² (preferably 0.5 to 1 Kg/cm ² ), and the thickness reduction rate of the foamed polystyrene (insulating substrate) after hot pressing is about 30%.

Through such heat-pressing operation, the surface portion of the heat-insulating substrate 1 is melted by the heat transmitted through the heat sink 3 and the back plate 4, and thereby the heat sink 1 is fused and joined to the heat sink 3 and the back plate 4. be converted into and at the same time the insulation board 1
shows a tendency to cause secondary foaming in the heat receiving area, so this secondary foaming tends to occur between the heat dissipation plate 3 and the back plate 4 where there is an escape area, that is, the pipe fitting groove 5.
Proceeding inward in the direction shown by the arrow in FIG. 4, the refrigerant pipe 2 is pressed toward the heat sink 3 and brought into close contact therewith, and the gap around it is filled to completely fix the refrigerant pipe 2. Realize the state. In this way, the refrigerant pipe 2 can be closely fixed to the heat sink 3 by the secondary foaming of the heat insulating board 1, so that the pipe fitting groove 5 formed in advance in the heat insulating board 1 can be easily fitted into the refrigerant pipe 2. In consideration of the size, it is advantageous to form the pipe slightly larger than the pipe diameter.

Therefore, after the above heat pressure operation, the temperature at 0 to 80℃ is 0.1 to 10.
By performing a cooling operation for about a minute and taking out the laminate from the press, the desired heat-insulating wall panel P with a condenser as described above can be obtained.

Such a manufacturing method involves bonding the heat dissipating plate 3 and back plate 4 to the heat insulating substrate 1 using a separate adhesive, or bonding the heat dissipating plate 3 and the back plate 4 to the heat insulating substrate 1 by injection foaming.
In addition to simplifying the manufacturing process, this method is much more advantageous in that the refrigerant pipe 2 can be completely brought into close contact with the heat sink 3 and that it can be fixed in place, compared to the case where the refrigerant pipe 2 is formed in between. .

Effects of the invention Since the insulating wall panel according to this invention has the above-mentioned configuration, although it constitutes the wall of the house frame by itself, the refrigerant pipe 2 can be attached to the house. By connecting to the refrigerant circuit of a room cooler, the refrigerant pipe 2 and the heat sink 3 constitute a condenser, which also functions as a cooling condenser.
Therefore, it is possible to incorporate the condenser of the room cooler into the wall of the house using a part of the building frame, and there is no need for a dedicated space for installing the condenser outdoors. In addition, since the heat from the refrigerant vapor can be radiated over a wide surface by the exterior heat sink, there is no risk of the forced air cooling fan becoming a source of noise. Therefore, there is no risk of causing heat damage indoors, and the indoor living environment of the house can be maintained in good condition without adversely affecting it.
