A main body case containing therein an air blower for circulating ambient air and a heat exchanger for exchanging heat between the ambient air circulated by the air blower and inside air, flange provided in main body case and having wall surface joining surface joined to wall surface where main body case is arranged, and cover attached to flange, having a louver in a side of the inside air, and a plurality of opening holes in a side of the ambient air and covering the ambient air side of main body case, thereby making an attachment and a detachment of cover easy, and achieving a reduction of a maintenance work.

Heat exchange device and heat generating element containing device using same

A shutter device reduces resistance in an air passage while maintaining air-tightness, thus reducing a load to a fan and a motor. A shutter mount is provided between an intake port adapted to be connected with a side from which air enters and a discharging port adapted to be connected with a side from which air is discharged. A shutter frame is inserted into an inside of the shutter mount. A shutter for preventing outside air from entering from the discharging port is mounted to the shutter frame. The shutter mount has a rib thereof for sealing a gap produced between the shutter and the shutter mount when the shutter is closed. The rib has an inner diameter substantially equal to a diameter of the discharging port as seen from the discharging port.

Shutter device and ventilation device

A control device accommodating unit () is provided in a section () accommodating an indoor air blower () adjacently to an indoor air flow-in port (), and an impeller () of the indoor air blower () is sequentially opposite to the indoor air flow-in port () and the control device accommodating unit () by rotation of the impeller (), and a space () is formed between the indoor air flow-in port () and the control device accommodating unit (). In this configuration, it is possible to obtain a cooling device decreased in drop of air flow rate and drop of cooling performance due to mounting a control device ().
