Method and device for air cooling

The invention relates to a method and a device for air cooling. The device comprises a rack having a computed tomography scanning means, and an air flow deflecting unit. The rack is provided with a tunnel-shaped opening, and patients can be guided into the tunnel-shaped opening. A first ventilation opening is disposed in the outer surface of the rack. The air flow deflecting unit is detachably disposed at the outer surface of the rack. Accordingly, under the running state of the device, a second ventilating opening is disposed in an area of the air flow deflecting unit, departing from the first ventilating opening; in the running state of the device, a bended flow path is formed between the first ventilating opening and the second ventilating opening. 本发明的各种实施例涉及用于空气冷却的方法和装置。本发明涉及种装置，具有计算机断层扫描设备的机架和气流偏转单元。机架具有隧道形开口，患者能够被引入到该隧道形开口中。机架在机架的外表面中还具有第通风口。气流偏转单元可拆卸地能够布置在机架的外表面处，特别是布置在机架的外表面处，以使得在装置的运行状态中，第二通风口构造在气流偏转单元的背离第通风口的区域中，并且在该装置的运行状态中，在第通风口和第二通风口之间形成有弯曲流动路径。
