Abstract: 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.

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).

Abstract: A heat exchanger device of the invention having a body case provided with a first air intake port and a first discharge port for a first environment in a front surface thereof, and a second air intake port and a second discharge port for a second environment in a back surface thereof, an air-blow fan for the first environment provided in the body case, and a heat exchanger inside the body case for exchanging heat between the air in the first environment and the air in the second environment, and is configured such that opposed two surfaces are provided with an air suction port for a first environment and an air suction port for a second environment, respectively, and the other surface is provided with an air blow-off port for the first environment and an air blow-off port for the second environment, respectively.

Abstract: The invention is provided with main body case (4) 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 (13) provided in main body case (4) and having wall surface joining surface (13b) joined to wall surface (2a) where main body case (4) is arranged, and cover (12) attached to flange (13), 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 (4), thereby making an attachment and a detachment of cover (12) easy, and achieving a reduction of a maintenance work.

Abstract: There is provided a cooler for heater-containing box in which an outside air fan for carrying air on an outside air path and an inside air fan for carrying air on an inside air path are arranged such that a rotating shaft of each fan is in parallel with an air intake direction, and a heat exchanger for exchanging sensible heat of outside air and inside air is arranged between the outside air path and the inside air path such that a suction port at a longitudinal air-path side of the heat exchanger is aligned with a blowout port of the fan. The cooler for heater-containing box capable of making the depth thinner can be provided.

Abstract: A heat exchange type cooling device includes an enclosure, an inside-air passage allowing inside air in the inside of the enclosure to flow through the inside-air passage and returning the flowing inside air to the inside, an outside-air passage allowing outside air at the outside of the enclosure to flow through the outside-air passage and returning the flowing outside air to the outside, an inside-air blower sending the inside air to the inside-air passage, an outside-air blower sending the outside air to the outside-air passage, a heat-exchanging element exchanging heat between the outside air flowing through the outside-air passage and the inside air flowing through the inside-air passage, and a heater for heating the inside air. The outside-air passage is independent from the inside-air passage. The heater is provided upstream of the heat-exchanging element in the inside-air passage.
