Electrical office equipment or household appliance e.g. notebook, cooling device, has hollow space, where part of space is formed as heat exchange surface and outer heat delivering surface is larger than inner heat absorbing surface
摘要
<p>The equipment/appliance has a closed hollow space receiving components and partially/fully filled with a non-conducting coolant e.g. oil. Part of the space is formed as heat exchange surface (19), and a gaseous medium flows on opposite side of the surface so that heat within the equipment/appliance is absorbed and dissipated. An outer heat delivering surface of the surface (19) is larger than an inner heat absorbing surface.</p>
