<p>In order to improve the transfer of heat within a heat exchanger one or more tubes (11) for a heat transporting medium are embedded by casting into a block (12a) of an aluminium alloy, or some other metal having high heat conducting capacity. The block is at its outwarded faces provided with surface-enlarging flanges (15), and is enclosed in a casing (13) which defines a passage for a second heat transporting medium flowing around the block (12a). A block can be prismatic or annular, and a number of blocks can be fitted within the same casing.</p> |
