Description

[Detailed Description of the Invention] The present invention relates to an improvement of a heat exchange device having a heat insulating material 4.

A conventional method and a method according to the present invention will be described when applied to an indoor unit of a sound air conditioner with heat exchange equipment.

In a conventional heat exchange device, a heat medium such as cold water or lake water flows through the internal metal, and a transport pipe connected to the heat exchanger passes through a holding plate, while this holding plate is connected to a heat insulating material adjacent to the heat exchanger side. There is.

In such a device, when the air conditioner is in a cooling operation or when the heating operation stops, water droplets condense on the surface of the retaining plate on the heat exchanger side.

When the water droplets descend along the retaining plate, the heat insulating material is adjacent to the retaining plate, so the water droplets wet the heat insulating material.

The present invention was developed in view of the above five drawbacks of the conventional heat exchanger, and its main purpose is to prevent water droplets condensing on the surface of the retaining plate on the heat exchanger side from wetting the insulation material.

Embodiments of the present invention will be described below based on drawings.

In Fig. 1, 1 is the casing of the indoor unit of the air conditioner, Ia and Ib are the upper and side panels that constitute the casing metal, 2 is the mounting base fixed to the middle part of the side panel 1b, and 3 is the casing of the indoor unit of the air conditioner. A heat exchanger is housed above the mounting base 2 in the casing 1, 4 is connected to the heat exchanger, and a transport pipe through which a heat medium such as cold water or muddy water flows, and 5 is the surface measurement pipe. This is a heat insulating material attached to the panel 1b in contact with the surface on the heat exchanger 3 side, through which the transport pipe 4 of one of the heat insulating bolts passes.

Reference numeral 6 denotes a measuring plate provided in contact with one side of the heat exchanger 3 through which the transport pipe 4 penetrates, and 7 represents a holding plate through which the transport pipe 4 penetrates and is in contact with the surface of the heat exchanger 3 side of the heat insulating material 5. It is a plate and has a guiding part 7alf, which will be described later.

Reference numeral 8 denotes a fixture consisting of a socket for fixing the holding plate 7 and the transport pipe 4, and 9 denotes a heat exchanger having one end fixed to the side panel 1b and the other end protruding from the heat insulating material 5 toward the heat exchanger 2 side. The heat exchanger is supported by the exchanger support.

Reference numeral 10 denotes a drain pan placed on the upper surface of the mounting base 2, and is disposed below the heat exchanger 3.

Reference numeral 11 denotes a double-shaft motor installed below the mounting base 2, and 12 represents a blower driven by the double-shaft motor. They are arranged on both sides of the mount 2 and are respectively attached to the mounting base 2.

FIG. 2 is an enlarged perspective view of the main part of the device shown in FIG. 1, and in FIG. The guiding part 7as is a plate-shaped mounting part that is in contact with the surface of the third side and through which the transport pipe 4 passes, and the guide part 7as and the mounting part 7b are formed by bending a single sheet metal and constitute the holding plate γ metal.

The upper surface of the guide portion 7a is inclined with respect to the horizontal plane, and the longitudinal center line l□ of the girder attachment portion 7b is inclined with respect to the longitudinal center line 12 of the heat insulating material 5.

Reference numeral 7c denotes a mounting hole provided in the mounting portion 7b, through which the holding plate 7 is screwed onto the side panel 1b.

Reference numeral 7d denotes a pair of attachment holes (only one is shown in gold in the figure) provided in the guide portion 7a.

9a is a plate-shaped fixing portion fixed to the surface of the surface measurement panel 1b on the heat exchanger 3 side; 9b is a plate that penetrates through the heat insulating material 5 and protrudes from the heat insulating material 5 toward the heat exchanger 3 side; The fixing portion 9a and the connecting portion 9b are formed by bending a single sheet metal to form the heat exchanger support 9 metal.

9c is a coupling hole provided in the coupling part 9;
The upper surface of b overlaps with the coupling hole (the coupling hole not shown) 7d while being in contact with the lower surface of the guide portion 7a, and is coupled to the guide portion 7a by a screw passing through these superposed coupling holes 7dt9ck. It is screwed into part 9b.

The transport pipe 4 is supported on the left side of the heat exchanger 3 by the holding plate 7 fixture 8 and the heat exchanger support 9, and on the right side (see FIG. 1) is supported by the metal heat exchanger support 9 on the side plate 6. By this, the heat exchanger is supported by three metals.

Since the structure shown in FIGS. 1 and 2 is as described above, water droplets condensed on the surface of the retaining plate 7 on the heat exchanger 3 side are removed from the surface of the retaining plate T on the heat exchanger 3 side. When the water droplets reach the upper surface of the guiding part 7a, the water droplets are guided to the drain pan 10 by the guiding part 7a whose upper surface is inclined with respect to the horizontal plane.
There is little risk of getting it wet.

In FIG. 3, the guide portion 7ae drain of the holding plate I is
One end of the heat exchanger 3 is placed on the upper end and supported by the retaining plate 7, and the other end is supported by a heat exchanger support (not shown) attached to the metal side plate 6 and side panel (not shown). It is supported in a similar way to that of

In the configuration shown in FIG. 3, water droplets condensed on the surface of the three heat exchangers of the holding plate 7 descend along the surface of the three heat exchangers of the holding plate 7, When the water droplets reach the upper surface of the guiding part 1a, they are guided to the drain pan 10 by the guiding part 7a, so there is almost no possibility that the water droplets will wet the heat insulating material 5.

Although the guide part 7a is placed on the upper end of the drain pan 10 in FIG. 3, the guide part 7a may be placed on the bottom surface of the drain pan 10.
0, and is connected to a separate heat exchanger support (not shown) and the holding plate 7 through a pair of coupling holes 7dk provided in the guide portion 7a by means of metal screwing or the like. Needless to say, one end of the heat exchanger 3 may be supported in a fixed manner.

As described above, the present invention includes the installation of the guiding part 7ak that guides water droplets condensed on the surface of the mounting part 7b and the fixture 8 on the heat exchanger 3 side to the drain pan 10 disposed below the heat exchanger 3. By providing it integrally with the portion 7b, there is an effect that there is almost no possibility that the water droplets will wet the heat insulating material 5.
