  • HEATING ELEMENT HOUSING DEVICE
    Publication number: 20150147951
    Abstract: A heating element housing device (7) comprises a heat exchange device (6) for cooling inside a cabinet (1) by exchanging heat between internal air (8) and external air (9). An exterior fan (22a) is disposed at a bottom portion of the cabinet (1) and an interior fan (21a) is disposed at an upper portion of the cabinet (1). A case (10) houses a heat exchanger (2). The heat exchanger (2) is provided with an internal air intake port (14), an internal air outlet port (15) and an external air intake port (16). An external air outlet port (11) is provided on a side of the case (10) opposite to a cabinet door (3) for blowing out the external air (9). The exterior fan (22a) and the interior fan (21a) are both centrifugal-type fans.

  • Cooling device
    Patent number: 8251136
    Abstract: A control device accommodating unit (15) is provided in a section (50) accommodating an indoor air blower (7) adjacently to an indoor air flow-in port (16), and an impeller (7c) of the indoor air blower (7) is sequentially opposite to the indoor air flow-in port (16) and the control device accommodating unit (15) by rotation of the impeller (7c), and a space (51) is formed between the indoor air flow-in port (16) and the control device accommodating unit (15). 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 (14).
