An apparatus is provided for transporting away heat from heated elements. The ap-paratus comprises a block (9; 18; 27) of a material having good thermal conductivity on to which the elements are provided in thermal contact. Channels (7,8; 17; 25) are provided in the block. A liquid, for example water, is forced to flow through the channels. Path means (10, 11; 15, 16; 28, 29) in the channels provide a spiral path for the liquid. Whirl means (7,8; 17; 25) in the liquid path provide turbulence to the streaming water. The channels could be made by tubes having corrugated thin walls and made by a non-corrosive material against the streaming liquid, such as steel, preferably acid proof stainless steel. The tubes could be cast, or fastened in some other way, in a material having good thermal conductivity, for example aluminium. A method for producing the apparatus is also disclosed. |
