Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air-cooled water cooling device that is efficient, compact, and lightweight.

Conventionally, there have been devices of this type as shown in FIGS. 1 and 2. In the figure, reference numeral 1 denotes an air coil, which, as shown in the second figure, is composed of a cooling pipe 1a, a heat insulating fin 1b, and a side plate 1c to which these are fixed. 2 is a blower assembly consisting of a blower and a bell mouth for cooling the air coil 1, 3 is an upper frame that supports the load of the blower assembly 2, 4 is a machine room, and 5 and 6 are arranged in this machine room 4. The water cooler and refrigerant compressor 7A and 7B are the air intakes of the air coil 1, and are composed of a lower intake 7A and a side intake 7B.

Define the next action. A high-temperature, high-pressure refrigerant gas (not shown) discharged by the refrigerant compressor 6 is cooled by the blower assembly 2 in the air coil 1 and becomes a high-temperature, high-pressure liquid refrigerant. Then, it is expanded by an expansion mechanism (not shown) to become a low-temperature, low-pressure liquid refrigerant, and further evaporated inside the water cooler 5 to become a low-temperature, low-pressure refrigerant gas. At this time, the water to be cooled is cooled and used for air conditioning and the like.

The low-temperature, low-pressure refrigerant gas is compressed by the refrigerant compressor 6 to become a high-temperature, high-pressure refrigerant gas, and by repeating this cycle, cooling water and the like are continuously supplied.

The blower assembly 2 cools the air coil 1,
The air is ventilated upward, and therefore a lower air intake port 7A and a side air intake port 7B are required, which are located at the top of the air coil 1 and on the air inlet side of the air coil. Air flows as shown.

Since the conventional air-cooled water cooling device is configured as described above, the width of the air intake port 7A is the first width.
Since there is only a distance indicated by There were drawbacks such as the need for an upper frame 4 for supporting the air coil 1 and the blower assembly 2.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional ones, and the air coil is configured in an inverted M-shape consisting of a vertical part air coil and an inclined part air coil, so that air can be sufficiently supplied from two directions. The purpose of the present invention is to provide an air-cooled water cooling device that can be installed in the air coil, uniformly and efficiently cool the air coil, and omit the upper frame by supporting the load of the blower assembly with the vertical partial air coil. shall be.

An embodiment of the present invention will be explained below with reference to the drawings. In FIGS. 3 and 4, reference numeral 1 denotes an air coil, which, as described above, is composed of a cooling pipe 1a, a heat insulating fin 1b, and a side plate 1c to which these are fixed. 2 is a blower assembly consisting of a blower and a bell mouth for cooling this air coil 1; 4
7A and 7B are the air intake ports of the air coil 1, and 7A and 7B are the air intake ports of the air coil 1. , a side air intake 7B formed on both sides of the air coil 1, and a lower air intake 7A formed below the air coil 1.
The air coil 1 has a side air intake port 7b.
Side air intake 7 allows maximum intake of air from
a vertical partial air coil 1 installed substantially vertically along B and supporting a blower assembly 2 located above;
B, and an inverted partial air coil 1A that is installed in a Λ shape surrounding the lower air intake 7A so that the maximum amount of air can be taken in from the lower air intake 7A.
It is formed into a letter shape.

The operation of the refrigerant gas is the same as that of the prior art, so a description thereof will be omitted.

The flow of air passing through the air coil 1 and cooling the air coil 1 is as indicated by arrow A in the third diagram. Here, the air passing through the vertical partial air coil 1B from the side air intake port 7B can be sufficiently secured, and the air flow through the air coil for the air taken in from the lower air intake port 7A is similar to that shown in FIG. As is clear from the comparison between Figure 3 and Figure 3, the width Y in Figure 3 is dramatically larger than the width X in Figure 1, and the air intake space can be constructed sufficiently wide, allowing the air coil to The cooling effect has been dramatically improved, and the overall width of the device can be reduced.

Further, the special upper frame 3 that supports the blower assembly 2 is not required, and the blower assembly 2 can be supported by the vertical partial air coil 1B, making it possible to efficiently reduce the size and weight.

As described above, according to the present invention, since the air coil has an inverted M-shape consisting of a vertical partial air coil and an inclined partial air coil, the air circulation to the air coil can be uniformly and maximized. In addition to dramatically improving the cooling of the air coil, the load of the blower assembly can be supported by the vertical partial air coil, making it possible to omit the special upper frame and creating an efficient, compact and lightweight air-cooled water cooling system. There are benefits to be gained.
