Description

  With the development of ultra-high-speed communication networks such as optical communication in the highly information-oriented society, the present invention can be used for various devices that have been used in dedicated buildings such as office buildings in general buildings, collective housing, and general homes. In addition to suppressing noise and vibration generated from the same equipment when installed in a building, fans, etc. even in buildings where environments suitable for the use of various equipment using high-speed and high-density semiconductor functional elements are not provided The present invention relates to a unit storage case having a silencing and damping function that can be used without using any cooling equipment.

In ultra-high-speed communication networks such as optical communication, dedicated equipment is required not only for switching stations but also on the terminal side. These devices use advanced semiconductor integrated circuits and perform ultra-high-speed signal processing. In order to guarantee a stable operation, it is necessary to forcibly convection with a large amount of air fan or the like to release the heat to the outside. And “Patent Document 2” and “Patent Document 3”. Each of the above devices generates noise and vibration in the operating part. Conventionally, soundproofing and air-conditioning equipment such as office buildings have been prepared, and there was no problem in dedicated buildings where the flow path was secured for each device by a cold air introduction path and a heat exhaust discharge path. Has become a big problem in general buildings and hinders its spread.
Japanese Utility Model Publication 4-85785 (FIG. 1) Japanese Patent Laid-Open No. 3-34395 (FIG. 1) JP-A-5-226864 (FIG. 1)

The “forced air cooling housing” of “Japanese Utility Model Publication No. 4-85785” of “Patent Document 1” houses a communication device in a cabinet (10), and a fan ( 6) A wind heading diagonally upward is generated and air in the cabinet (10) is discharged via the sound absorption guide plate (2) and the sound absorbing material (4) to cool and silence the communication device. is there. As described above, this known technique requires a separate fan (6). Moreover, although the air discharge structure is clear, the air intake means is unclear, and the overall flow of air is unknown.
“Electronic equipment cooling device” in “Patent Document 2” of “Patent Document 2” cools a substrate (6) disposed in a housing (3). The body fan (4) is arranged below the casing (3), and air is sucked from above the casing (3) and discharged from below the casing (3). In this case, a part of the exhaust gas that has absorbed the heat generated by the substrate (6) flows upward and mixes with the intake air (so-called heat feedback), which causes a problem of greatly reducing the cooling efficiency.
In addition, the “noise reduction structure of an electronic device” in “Japanese Patent Laid-Open No. 5-226864” of “Patent Document 3” requires a separate fan (5) and the like, and the air flow is “ Similar to Patent Document 2, there is a problem in that heat feedback occurs from above to below.

  In any case, the casing for storing the communication electronic device must be stored in a locked metal casing in order to ensure security. Therefore, it is necessary to use a dedicated housing that has an appropriate intake / exhaust port and flow path so that the housing is provided with soundproofing and vibration isolation functions and the cooling capacity is not lowered. The noise generated from these devices is roughly divided into two types: wind noise generated by forced air cooling and vibration sound generated by vibration. The wind noise is a duct-like structure whose channel is covered with a sound absorbing material. It can be solved by forming an object. In addition, these units are designed to be mounted in a rack, and the input / output and operation / display units are concentrated on the front and back, and one of the side surfaces is designed as an intake port and the other as an exhaust port. It is possible to easily construct a continuous silencing mechanism from the body's external air inlet to the external air outlet via the unit.

  At this time, vibration is absorbed by adding an anti-vibration function to the unit holding mechanism, and for sound generated from the unit surface, a sound absorbing material is affixed to the inside of the housing including the door to leak outside. Can be prevented.

  However, the duct becomes a new load for the fan that generates airflow, and there is a danger of impairing the cooling capacity that was initially expected, and the pressure between the exhaust port of the unit and the exhaust side duct is the highest, and heat is generated during this period. There is also a possibility that a phenomenon called heat feedback that causes the exhaust gas to leak into the housing and mix with the cooling air and extremely reduce the cooling efficiency is caused. This phenomenon also occurs in the positional relationship of the intake / exhaust ports of the housing. In particular, when the exhaust port is arranged at the lower portion and the intake port is placed at the upper portion, the cooling effect cannot be expected.

  Therefore, a duct having an opening area sufficiently larger than the opening area of the unit-side exhaust section on the exhaust side where noise is high is closely attached to the exhaust port of the unit to maintain airtightness and promote the exhaust of thermal exhaust outside the housing. The intake side on which the noise is relatively low can be reduced by providing a housing inlet at a position as far as possible from the unit opening and passing through the housing covered with the sound absorbing material. At this time, by providing the housing intake port on the bottom surface and the housing exhaust port in the center of the side surface, it is possible to prevent heat feedback and to efficiently dissipate heat.

  The present invention has been invented in view of the above circumstances, and does not arrange a separate fan in the housing body as in the known art, and prevents heat feedback by devising the air flow path and unit. Intake air intake that is arranged in close proximity between the unit and the housing body, with a straight and horizontally long exhaust duct having an opening area wider than the exhaust port area of the housing and having a lateral dimension equal to the lateral width of the housing body Providing a housing for storing a unit having a noise reduction and vibration control function that can be installed indoors and outdoors, and has a heat dissipation, noise reduction, and vibration control effect. Objective.

  In order to achieve the above object, the present invention incorporates an electronic device and its peripheral devices and a fan for blowing air, and has an intake port and an exhaust port on opposite sides, and as a countermeasure against noise reduction and / or prevention. Stores units that are not equipped with vibration countermeasures, reduces heat and noise and / or vibrations generated from the units, and stores units installed outdoors or indoors, with sound-absorbing materials attached to the exposed surfaces inside The housing for a unit is a box-shaped housing that does not have a fan other than the fan included in the unit and that has an opening that is opened and closed by an opening / closing door on the front side. An intake air introduction portion and an exhaust air introduction portion that are interposed between the inner surface of the main body and the outer surface of the unit body and the outer surface of the unit where the intake port and the exhaust port are formed. And communicating with the exhaust introduction part of the housing body An exhaust duct formed on the surface side and having an opening area larger than the exhaust port area of the unit; a housing exhaust port that communicates straight with the exhaust duct and is formed in a side surface of the housing body; and A housing air inlet formed on a lower surface of the housing body away from the outlet, and the exhaust duct includes an inner surface on the rear surface side of the housing body and an outer surface on the rear surface side of the unit. And having a lateral dimension equal to the lateral width of the casing body, and is formed in a horizontally long shape formed in a straight line.

  According to a second aspect of the present invention, the unit stored in the housing body is housed in a lid that is cantilevered by the housing body.

  According to the case for housing a unit having a silencing and damping function according to claim 1 of the present invention, air enters the case body from the case inlet provided on the lower surface of the case body on the opening side. , Enters the unit via the intake inlet located at a position away from this position and the inlet of the unit, proceeds through the unit by the fan in the unit, and is sent to the exhaust outlet and the exhaust inlet of the unit to introduce the exhaust Is sent to the exhaust duct and discharged from the casing exhaust port located away from the casing intake port. The heat flow of the unit is performed by the above air flow, and noise and vibration suppression generated from the unit are reduced by using this air flow together with the sound absorbing material and the vibration damping material. Further, no thermal feedback occurs due to the positional relationship between the housing intake port and the housing exhaust port.

  According to the unit storage case having the silencing and damping function according to claim 2 of the present invention, the unit is held by the lid, and the lid is rotatably supported by the case main body. Is easily done.

Enter unit 50. Since the unit 50 has a built-in fan 50c, the air that has entered the unit 50 through the intake port 50d travels through the unit 50, and the opening of the unit holding unit 10 opens from the exhaust port 50e of the unit 50 as indicated by an arrow C. The exhaust gas introduction part 3 enters into the exhaust gas introduction part 3 through the opening part 3b of the exhaust gas introduction part 3 through the part 10b. The air that has entered the exhaust introduction section 3 enters the exhaust duct 4 that communicates with the exhaust introduction section 3, travels through the exhaust duct 4, and is discharged to the outside from the casing exhaust port 5 of the casing body 1. Since the intake air introduction portion 2 is disposed in close contact with the inner surface of the housing body 1 and the side surface of the unit 50 where the intake port 50d is located, all intake air enters the unit 50, and the intake air cools the unit 50 while the exhaust port 50e side.
