Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a heat exchange device for cooling the inside of, for example, a sealed casing.

[Conventional technology]

FIG. 1 shows a conventional heat exchange device disclosed in, for example, Japanese Utility Model Application Publication No. 48-79442. )
A frame body (5) is formed with a second air flow path (4) through which outside air flows, and (5) is connected to the first air flow path (3). It is a tube body (hereinafter referred to as a heat pipe) consisting of a plurality of heat pipes in which the air flow path (4) is disposed on the other side, that is, the heat dissipation part (5b), and the inside is filled with Freon gas after vacuum degassing. A hydraulic fluid is enclosed. (6) is the fin attached to this heat pipe (5) Iζ, and these are the heat pipe (5) and fin (6).
A heat exchanger main body (7) is constructed from Iζ. (8)
This is the first blower separately placed in the air flow path (3) of
). (9) is placed separately in the second air flow path (4). : Second blower, which connects outside air to a heat pipe (
5) Blowing air to the heat radiating part (6b). αO is provided removably from the outside in the second air flow path (4) on the opposite side of the second blower (9) via the heat dissipation part (6b) of the heat pipe (5). This prevents the intrusion of dust, etc. mixed into the outside air. This heat exchange device has a partition plate (2) of a heat pipe (5) as shown in Fig. 2 and Fig. 8.
), that is, the heat receiving part (5a) can be inserted into the closed structure 0 and used as a closed cooling device.

Next, the operation when the closed structure 0 is provided with a heat exchange device will be explained. Inside air is blown into the first air flow path (3) in ml by the frame body (1) after being sucked in by a (alt). ) Iζ is blown.At this time, the heat of the inside air is transferred to the fins (6) and the heat receiving part (5a) of the heat pipe (5)1, and the working fluid in the heat pipe (5) is vaporized. The vaporized vapor is transferred to the outside air side within the heat pipe (5), that is, the heat dissipation part (5b) of the heat pipe (5).
Move to. The outside air is sucked in by the second air gutter (9) in the second air flow path (4) and then guided by the frame (1).
Heat dissipation part (5b) of heat pipe (5), fin (6)
Air is blown. At this time, the heat dissipation part (5b) and the fins (6) of the heat pipe (5) are cooled by the outside air 1, and the steam inside the heat pipe (5) is condensed and releases latent heat of condensation to the outside air. The condensed working fluid moves within the heat pipe (5) to the inside air side, that is, to the heat receiving part (5a) of the heat pipe (5) and returns. In this way, the heat of the inside air is transferred to the outside air by repeating vaporization and liquefaction inside the heat pipe (5).

Follow. Then, the inside air enters the heat receiving part (5a) of the heat pipe (5),
When the air passes through the fins (a), heat is removed from the air, the turbidity decreases, and the air is cooled. In this way, the closed structure a
The inside of υ is cooled.

Since the conventional heat exchange device is HIM1 as described above, the moisture contained in the outside air is blown along with the outside air to the heat dissipation part (5b) of the heat pipe (5) by the second blower (9). nru. Although some of the moisture is prevented from entering by the filter cA0, the remaining moisture accumulates on the heat exchanger body (7), the spray plate (1), and the partition plate (21).This moisture is scattered near the closed structure I. The disadvantage is that it gets soaked with water.Also,
If the seal between the frame body (1) and the partition plate (21) is poor, there is a risk that the particles may enter the closed structure and cause damage to internal equipment (not shown).

[Summary of the invention]

This invention has been made in view of the above-mentioned drawbacks of the conventional devices, and provides a highly reliable heat exchange device by providing a drain means on either the frame or the partition plate. be.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 4, (1) to (7) are similar to the configuration of the conventional device described above. Q2 is the flange part provided on the partition plate (21), (to) is the seal gasket that is attached between this flange part (2) and the frame body (1), α4 is the flange part @,
Seal packing α] is a drain port that penetrates the frame (1), and is shaped by the partition plate (1) and the flange @, lff
This is to drain the water aυ that has accumulated in the reservoir area.

The water that came in with the outside air (4) gathers in another area surrounded by the partition plate (21) and the flange MA@. Also, the water that came through the frame (1) is collected in the closed structure due to the seal packing αJ. Make sure that the partition plate (21 and flange part) does not flood into the aD side.
6) It stays in the area surrounded by water as water. The standing water is provided in the frame body (1) and the flange portion υ seal packing (end), and is discharged to the outside through a drain port α4.

In addition, in the above embodiment, a drain port (to) is provided, but a drain plug 1ζ or an auto-drain device or the like may be provided.

Further, in the above embodiment, explanation has been made regarding lζ in the case of water intrusion, but an oil-conducting liquid may also be used, and the same effect fIm as in the above P embodiment is produced.

〔Effect of the invention〕

As described above, according to the present invention, since the F lens means is provided on either the frame body or the partition plate, the shadow W7/
It is possible to drain the accumulated liquid without applying any water, and also to prevent the accumulated liquid from entering the closed structure, resulting in a highly reliable product.
