Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a cabinet for audio equipment that is suitable for stacking, and in particular to a cabinet for audio equipment that is convenient for stacking.

[Prior art and problems] Electronic audio equipment, such as audio equipment, is often used in parallel on a flat surface.
More often, cases are used in stacks, where the equipment is housed in a rack rather than simply stacked on top of each other.

When using audio equipment in a stacked manner, the problem is how to dissipate the heat generated by each equipment.If heat is not dissipated reliably, electronic components may be affected by the heat. There was a problem with performance deterioration.

Therefore, in order to improve the passage of cooling air, devices are stacked one on top of the other with the space above each device separated.

Such usage has the drawback that not only does the volume of the entire cabinet become large, but also the space occupied during use becomes large.

The purpose of this invention is to reduce the overall volume when various devices such as audio equipment are used in a stacked state, and to provide a cabinet that can reliably disperse and dissipate the generated heat. It is.

[Means for solving problems]

In order to achieve this purpose, this idea
The cabinet body includes a cabinet body and a bonnet that is placed over the cabinet body. is opened and has a heat dissipation passage having a ventilation hole communicating with the internal space of the cabinet body, the lower end of the heat dissipation passage becomes a protruding edge, and is adapted to fit into the upper end of the lower heat dissipation passage,
The bonnet, when placed over the cabinet body, has a ventilation hole corresponding to the heat radiation passage, and guides hot air within the cabinet body to the heat radiation passage, into which the protruding edge of the upper cabinet can fit into the heat radiation passage. It is characterized in that the upper and lower heat dissipation passages are in communication with each other, and the heat can be discharged from the upper opening.

〔Example〕

Next, embodiments of this invention will be described in detail along with embodiments shown in the drawings. In FIGS. 1 to 4, reference numeral 1 indicates a main body of the cabinet, and reference numeral 2 indicates a bonnet that covers the main body 1 of the cabinet. The cabinet body 1 has a box shape as a whole, but it has left and right side plates 12, 13 provided on both sides of the bottom plate 11, and a back plate 14 fixed to the bottom plate 11 and the side plates 12, 13. The front and top surfaces are open. An inner plate 15a is provided on the inner surface of the side plates 12 and 13 with a large number of ventilation holes to form heat radiation passages 15 and 16 in parallel with each side plate.
16a is arranged so as to protrude into the space inside the cabinet body 1, and the inner ventilation holes 15a, 1
The front and rear end surfaces of 6a are integrally formed with the side plates 12 and 13 by end plates 15b and 16b.

The heat dissipation passages 15 and 16 have such a configuration, and the edges of the upper openings 15c and 16c have stepped portions 15.
d, 16d are formed, and on the other hand, the lower surface of each heat dissipation passage 15, 16 becomes a lower opening 15f, 16f, and the edge thereof is formed into a stepped portion 15d, 16d of the upper opening 15c, 16c of the lower cabinet. It has protruding edges 15g and 16g that can be fitted and rested on.

Further, the bonnet 2 is formed in a gate shape by a top plate 21 and side plates 22, 23 formed on both sides of the top plate 21.
The top plate 21 is sized and shaped so that it can be closely attached to the outside of the side plates 12 and 13, and the top plate 21 can close the opening on the top surface of the cabinet body 1.

Ventilation holes 21a, 21a are bored near both left and right ends of the top plate 21 at positions corresponding to directly above the heat radiation passages 15, 16 of the cabinet, and these vent holes 21a are located near the protruding edges 15g of the cabinet body 1. , 16g is determined to be large enough to penetrate.

In addition to the above, the cabinet main body 1 is
As shown in the diagram as a perspective view, the side plates 12,
13 and the inner plates 15, 16 between the heat radiation passages 15, 1
6 as well as inner plates 15a, 16a.
is formed by bending the side plates 12, 13, omitting the side plates 12, 13 in that part, and creating a heat radiation passage 15, between the side plates 22, 23 of the bonnet 2 and the inner plates 15, 16. 16 may be formed.

Furthermore, as shown in FIG.
5 and 16 are provided at both ends of each of the side plates 12 and 13, in other words, at the four corner positions of the cabinet, and correspondingly, the ventilation holes 21a of the bonnet 2 are also formed at the four corner positions of the top plate 21. It can be something.

Such a cabinet can be integrally molded from synthetic resin, or only the inner plate can be molded from synthetic resin, and the material can be freely selected.

A cabinet for audio equipment suitable for stacking according to this invention houses electrical components that generate heat such as an amplifier in a cabinet body 1, and a bonnet 2 is placed over the cabinet body 1 to cover the top surface of these electrical components to prevent dust, etc. When using an appropriate number of stacked cabinets, when stacking an upper cabinet on top of a lower cabinet, the upper cabinet has a protruding edge 15g
16g to the upper opening 1 of the lower heat radiation passages 15 and 16
5c, 16c to connect the heat radiation passages 15, 16 in the vertical direction,
Used by combining the upper and lower cabinets.

At this time, heat generated from electrical components in the cabinet body 1 is transferred to the inner plate 1 by the air flow.
The air is guided from the ventilation holes 5a and 16a to the heat radiation passages 15 and 16, and becomes an upward airflow to the upper opening 1 of the heat radiation passage.
Heat dissipation passages 15, 1 further above 5c, 16c
6, and finally the uppermost opening 15
c, released from 16c.

It is also possible to accommodate a conventional cabinet in a cabinet of this invention as shown in FIG. 4K.

[Effect of idea]

As is clear from the above explanation, the audio equipment cabinet suitable for stacking this invention is
It consists of a cabinet body and a bonnet, and the cabinet body has heat radiation passages on both sides.
When a large number of cabinet bodies are stacked on top of each other, the upper and lower heat radiation passages are configured to communicate with each other, and the heat radiation passages are configured so that they can fit into each other, so that the heat generated by the equipment can be reliably released to the outside. It is possible to prevent the influence of heat on the upper equipment, and furthermore, the heat dissipation passages of the upper and lower cabinets are connected by fitting the protruding edges, thereby making it possible to strengthen the coupling in the left and right direction.
