Abstract

PROBLEM TO BE SOLVED: To enable the satisfactory cooling if the blowing direction does not agree with the piercing directions of exhaust holes of an exhaust window member 2 by providing distribution boards extending from this member close to the blow side of a cooling fan at the least distance. SOLUTION: An exhaust window member 2 has distribution boards 4 extending from this member close to the blow side of a cooling fan 3 at the least distance. For exhaust air from a cabinet K, the fan 3 is driven to cause an air flow directed upwards which is guided upwards along the distribution boards 4 at both sides thereof and bent through a bends 5 towards exhaust holes 1, thus smoothly exhausting the air, without striking against the cabinet K to cause the turbulence. This reduces the air flow turbulence and hence raises the exhaust efficiency whereby the internal temp. rise of machines in the cabinet K can be suppressed low.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIG. This embodiment shows a cooling device 10 that discharges air inside a housing K of equipment to perform cooling, and FIG. 1 is a plan view in which the housing is cut away.

This cooling device 10 includes an exhaust window member 2 having a plurality of exhaust ports 1 provided on the wall surface of the housing K, and the housing K.
And a cooling fan 3 that blows air from the inside of the housing toward each exhaust port 1.

The exhaust window member 2 is equipped with a straightening plate 4 extending from the exhaust window member 2 to the front of the blower side of the cooling fan 3 at the shortest distance.

The cooling fan 3 is arranged in the corners of the housing K formed by two wall surfaces that are orthogonal to each other due to the arrangement of the internal structure of the machinery and the positional relationship with the heat generating source. It is arranged obliquely to the wall surface. Then, the cooling fan 3 exhausts air vertically upward in FIG.

On the other hand, on each of the wall surfaces of the housing K facing each other, there are provided a plurality of elongate hole-shaped exhaust ports 1 (the longitudinal direction of which faces the front and back direction of the page) formed perpendicularly to the respective wall surfaces. The exhaust window member 2 is formed from the exhaust ports 1 and a part of each wall surface forming a frame around the exhaust ports 1.

The straightening vane 4 extends from the orthogonal portion of the two wall surfaces of the housing K, that is, the corner portion (the upper end portion of the housing K in FIG. 1) along the blowing direction of the cooling fan 3 to the front of the cooling fan 3. It is set up. Further, at the root portion of the straightening vane 4 on the exhaust window member 2 side, from the both surfaces of the straightening vane 4,
A curved portion 5 that forms a gently curved surface is provided toward the two exhaust ports 1 and 1 on both sides thereof.

With the above structure, when the air inside the housing K is exhausted, the cooling fan 3 is first driven to generate an upward air flow in the figure. This air flow is guided upward on both sides of the straightening vane 4 along the straightening vane 4 and is further guided to the exhaust port 1 by the curved portion 5 so that the airflow collides with the casing K and is smooth without causing turbulent flow. Is exhausted. That is, since the turbulence of the air flow is reduced, the exhaust efficiency is improved, and the rise in the internal temperature of the housing K of the machinery can be suppressed to a low level.

As for the current plate 4, the exhaust window member 2
The exhaust ports 1 may be provided so as to be partitioned from each other over the entire area.

That is, as shown in FIG. 2, the straightening vanes 4 may be installed evenly parallel to the cooling fan 3 between the adjacent exhaust ports 1 of the exhaust window member 2. As a result, the airflow from the cooling fan 3 is guided to the exhaust port more smoothly without colliding with the housing K and generating turbulence. Therefore, as in the case of FIG. 1, the exhaust efficiency is increased, and the rise in the internal temperature of the housing K of the machinery can be suppressed low.

Here, the current plate 4 may be integrated with the housing K or may be a separate member.

[0025]

According to the present invention, the air flow from the cooling fan is guided to the exhaust port by the straightening plate to prevent the occurrence of turbulent flow due to the collision with the housing, etc., thereby smoothly inside the housing. It is possible to exhaust the air.

In particular, it is possible to effectively exhaust the internal air even when the blowing direction of the cooling fan and the penetrating direction of the exhaust port do not coincide with each other inside the housing due to the internal structure of the machinery and the like. Is.

Therefore, by equipping the equipment with the present invention, it is possible to improve the exhaust efficiency and the cooling efficiency and suppress the rise in the internal temperature of the equipment to a low level.

Further, by providing a rectifying plate for each of the plurality of exhaust ports so as to partition the respective exhaust ports from each other,
The air flow from the cooling fan can be more smoothly guided to each exhaust port, the air inside the housing can be exhausted more effectively, and the exhaust efficiency and the cooling efficiency can be improved.

Further, by providing a curved portion at the root portion of the straightening vane on the side of the exhaust window member, turbulent flow is prevented from occurring at the joint portion between the root portion of the straightening vane and the exhaust window member, and the housing is smoother. It is possible to exhaust the air inside.
For this reason, it is possible to further improve the exhaust efficiency and the cooling efficiency and suppress the rise in the internal temperature of the machinery.

Since the present invention is constructed and functions as described above, it is possible to provide an excellent cooling device which has not been heretofore available.
