Summary:PROBLEM TO BE SOLVED: To provide a heat exchanger capable of cooling an inverter device without using excess appliances and electric power by cooling the inverter device by utilizing the wind flow generated by driving the fan, and reducing the number of air-cooling fans, for example, for the inverter device or the control panel.SOLUTION: An inverter unit IVU that comprises: an inverter 8 which enables the speed change of a motor 7; an inverter control part 51 for controlling the movement of the motor 7 via the inverter 8; and a casing 52 for accommodating the inverter 8 and the inverter control part 51. The inverter unit is attached to a casing H of a heat exchanger body to form an opening h in the casing H; and by utilizing the air flow which is sucked in the heat exchanger body by passing through the opening h due to the negative pressure formed by a fan device 3, the inverter unit IVU is cooled.SELECTED DRAWING: Figure 5 【課題】ファンの駆動により生じる風の流れを利用してインバータ装置を空冷し、インバータ装置または前記制御盤の空冷用ファン等を削減することにより、余分な設備及び電力を使用することなくインバータ装置を冷却することができる熱交換器を提供することを目的とする。【解決手段】モータ７を変速可能とするインバータ８と、インバータ８を介してモータ７の動作を制御するインバータ制御部５１と、インバータ８とインバータ制御部５１とを収容するケーシング５２とを備えたインバータユニットＩＶＵを熱交換器本体の筺体Ｈに取り付け、筺体Ｈに開口部ｈを形成し、ファン装置３により形成される負圧により開口部ｈを通って熱交換器本体内に吸い込まれる空気の流れを利用してインバータユニットＩＶＵを冷却する。【選択図】図５
