Air duct and electronic equipment using the air duct

Abstract

Abstract of the DisclosureThe invention relates to an air duct for allowing cooling air to flow toward an electronic equipment, and provides the air duct for allowing cooling air to flow installed in a space in the equipment and also provides an electronic equipment using the same air duct. The air duct is structured to be formed of an elastic material, and has a duct body, a ventilation path, an intake part, and an exhaust part. The duct body is detachably installed in a space of an interior of the equipment, and the ventilation path through which air passes is formed in the duct body, and an intake part for taking air in the ventilation path and an exhaust part for exhausting air through the ventilation path are formed respectively in the duct body.

Description

Detailed Description of the InventionBACKGROUND OF THE INVENTION[0001] 1. Field of the Invention:[0002] The invention relates to an air duct for forming an air path in a space inside electronic equipment, particularly, an air duct having a structure which is easily disassembled and assembled and electronic equipment using the air duct.[0003] 2. Description of the Related Art:[0004] Heat radiation and cooling in electronic equipment are conventionally indispensable to prevent the deterioration and keep stability and reliability of the operation of the electronic equipment. A cooling fan has been generally used for cooling the electronic equipment, and heating portion such as heating components and the like is cooled by air which is taken in the electronic equipment. For example, if a cooling fan is installed at the rear panel side to exhaust air, cooling air is sucked from the front panel side and so forth into the electronic equipment and it flows in the electronic equipment so ...

AI Technical Summary

Benefits of technology

[0015] With such an air duct, the duct body having the ventilation path, the intake part and the exhaust part may be structured, for example, by a first vertical wall 58, a second vertical wall 60, bridging parts 62, 64. That is, the first vertical wall is provided along a member facing the space of the interior of the equipment, and the second vertical wall is spaced from the first vertical wall, and provided along the member facing the space, and then the bridging parts bridge over the first vertical wall and the second vertical wall, wherein the first vertical wall and second vertical wall are supported by the bridging parts. As mentioned above, the duct body can form the ventilation path, the intake part, the exhaust part with a simple structure, and it singly implement a duct function.

[0022] Further, electronic equipment of the invention is electronic equipment having one or not less than two various equipment in a housing and has the air duct 24 and a fan unit 26. The air duct 24 is detachably installed in the space 20 of the housing (exterior case 4, top plate 36) to form the ventilation path 28 through which the air is allowed to flow in the housing. The fan unit is installed in the air duct, and the cooling air is forced to flow through the ventilation path. With such a structure, the cooling air can be allowed to flow in the equipment through the air duct, and the air duct can be easily detached and attached. Further, it is possible to realize the electronic equipment having high cooling effect and the fan unit 26 installed in the air duct 24 can be easily replaced with another.

[0023] With such electronic equipment, a first window 34 through which the fan unit 26 is attached to, or detached from the air duct 24 is formed in the air duct, and a second window 40 corresponding to the first window 34 is formed in the housing (top plate 36) of the electronic equipment, wherein the first window and the second window can be opened or closed by a cover member 44 provided in the housing so that the first and second windows can be opened or closed by the cover member 44 and the fan unit can be easily attached to, or detached from the air duct through the first and second windows.

Problems solved by technology

Further, with such a chassis structure, it is not possible to design the air duct and the housing separately from each other so that they can not be assembled or disassembled.

Replacement of the ventilator requires an operation for removing the front cover plate and the front face sealed plate, then removing a metallic enclosure enclosing the chassis, and separating the upper portion from the lower portion of the chassis, which is very troublesome and takes labor.

This technique is however discloses that the chassis per se is merely rendered to be air duct, and an air duct is not formed relative to a specific component, and the replacement of a fan requires the operation for removing the top plate from the chassis and removing the sealed case from the chassis, which is very troublesome and takes labor.
