A HEAT EXCHANGE DEVICE

摘要

A heat exchange device with a thermal element (4,5) for heating or cooling, an impeller (3) for creating an air current from an ambient space over a surface of the thermal element, and a chassis (2) housing the thermal element and the impeller. To facilitate easy disassembly for cleaning and maintenance and to reduce noise, the thermal element or the impeller is attached to the chassis by use of corresponding surface portions (13,14) one of which forming with a plurality of protruding elements adapted to be entangled in the other surface portion, sometimes referred to as fabric fasteners. The invention further provides a method of reducing noise in a heat exchange device and a method of assembling a heat exchange device.
