Abstract

PURPOSE:To improve the ventilating effect by means of a cooling device by opening a shutter when a small case is put into a housing and then closing the shutter when the small case is drawn out of the housing. CONSTITUTION:The projections 25 are provided to a chassis cover 3 of a housing 1 as well as to a chassis 7. At the same time, a hook part 26 is provided at the tip of a slide cover 23a of a shutter member 23. Thus the part 26 engages the projections 25 respectively. When a small case 5 is put into the housing 1, the covers 23a and 23b are put on each other together with covers 23b and 23c. When the case 5 is drawn out of the housing 1, a spring 25 is put between the rear end part of the case 5 and the cover 23a of the member 23 to cover an opening 24 when the part 26 is released automatically from the projection 25. In such a constitution, the air given from a fan passes through the opened shutter opening of the case 5 as shown by an arrow head C. This improves the ventilating efficiency.

[Problem that the invention seeks to solve]

According to the conventional configurations of the above-mentioned casing and small casing, there is a problem that a sufficient cooling effect cannot be obtained only by the slit 18 formed in the bubble power center small casing in which the bubble memory is built-in. Furthermore, in the second to fifth fans 13a, 13b, 13c, and 13d that cool two small cases simultaneously, if only one small case is inserted and the other small case is not inserted, Since the opening area on the side where the body is not inserted becomes larger, more air is sent out from this direction, which causes a problem of lowering the cooling efficiency on the side where the small housing is inserted.

[Means for solving problems]

The present invention was made in view of the above-mentioned drawbacks, and its purpose is to open the shutter when inserting a small case into the case and close the shutter when pulling out the small case from the case. The method is to increase the ventilation effect by using a cooling device in the case.

A plurality of small casings such as bubble cassettes can be freely inserted into the casing, and a cooling means is provided.

The heat generating member inside the small casing is cooled.

This is achieved by a case cooling device characterized in that a shutter member disposed between the small case and the case is opened when the small case is inserted into the case.

[For production]

In the present invention, shutter members are arranged on the casing and small casing sides, and the shutter is automatically opened by the insertion operation when the small casing is inserted into the casing through a cooling means such as a fan disposed inside the casing. A cooling device for a housing which increases the ventilation efficiency of the cooling means and closes the above-mentioned shaft in conjunction with the detachment operation when the small housing is removed from the housing to prevent foreign matter and dust from entering the small housing. This is what we provide.

〔Example〕

Hereinafter, two embodiments of the cooling device for a housing according to the present invention will be described in detail with reference to FIGS. 1 to 8. FIG. 1 is a cooling device for a housing according to the present invention, and FIGS. 2 and 3 are plan views of a small housing inserted into the housing of FIG. 1, showing the shutter in an open state and a closed state. FIG. 4 is a side sectional view showing the configuration for opening the shaft of the small casing, FIG. 5 is a side sectional view showing the configuration for closing the small casing, and FIG. 6 is a side sectional view showing the configuration for closing the small casing. 7 and 8 are side sectional views of the casing and the small casing for explanation, and FIGS. 7 and 8 are line side views showing the state of the shutter having the shutter member on the casing side when the small casing is inserted and the state after insertion. It is.

In FIG. 1, the same parts as in FIG. 9 are denoted by the same reference numerals and redundant explanations are omitted. For example, when two small casings 5 are inserted at the lower end of the chassis 7, a second ventilation passage 19 is inserted through one ventilation passage 19. A fan 13a is used to exhaust the air, slit openings 20a and 20b are formed in the ventilation passage and the chassis, respectively, and a shutter member 2 is provided to cover the slit openings. As shown in FIG. 2, the bubble memory capsent small cylinder 5 has a bubble memory 22 inside thereof, and as shown in FIG. A circuit with a small amount of heat is placed at the bottom end of the section. That is, the small housing 5 has an opening 24 in its upper and lower surfaces, and a shutter member 23 that slides through the opening.
For example, three slide covers 23a, 23b, 23c
More.

When taken out from the housing 1, the opening 24 is opened as shown in Figure 3.
Only the slit 18 or the ventilator is formed, and the shutter is closed and the opening 24 is closed.
When inserting the housing, the slide covers 23a and 23b of the shutter member 23 are slid and stacked on the slide cover 23c. A specific example of the configuration is shown in FIGS. 4 and 5. In FIG. 4, protrusions 25 are provided on the chassis cover 3 and chassis 7 of the housing I, and a slide cover 23a of the shutter member 23 is provided.
A locking piece 26 is provided at the tip of the housing to engage with a protrusion provided on the chassis and chassis cover. Also, when inserting the small case into the case, the slide covers 23a and 23
b, 23b and 23c are configured to overlap each other.

Further, when the small case is pulled out from the case as shown in FIG. The opening 24 is covered when the locking piece is released from the portion 25. With this configuration, air is blown from the fan in the direction of arrow C as shown in Figure 6.
As shown in (the reverse direction is also possible), the efficiency of air blowing by the fan is increased through the shirt opening of the small casing.

In the case shown in FIGS. 7 and 8, the shutter member is attached to the housing 1.
7 is a line side view showing the open and closed state of the shutter 21 when it is installed in the ventilation passage 19 provided at the lower end of the chassis 7. FIG. 7 shows the state before the small housing is inserted into the housing 1. The shutter member 21 is composed of slide covers 21a and 21b, and the front of the slide cover 213 has a protrusion 21C.
is provided, and when inserting the small casing into the casing, the back of the small casing engages with the protrusion 21c, and while pressing it, move the shutter in the direction of arrow E.
move in the direction. Therefore, the slit opening on the second ventilation passage 19 is opened, and when the small casing is completely inserted into the casing as shown in FIG.
By rotating 3a to 23d, the wind efficiently cools the heat generating members inside the small housing as shown by the arrows. When the small casing is removed from the casing, although not shown, the spring force returns it to the state shown in Figure 7.

〔Effect of the invention〕

Since the present invention is configured and operated as described above, it has the characteristics of being able to effectively cool a heat generating member such as a bubble memory cassette and correcting the unevenness of air blowing especially when a small casing is not inserted. .
