PCT No. PCT/SE90/00461 Sec. 371 Date Dec. 24, 1991 Sec. 102(e) Date Dec. 24, 1991 PCT Filed Jun. 27, 1990 PCT Pub. No. WO91/00488 PCT Pub. Date Jan. 10, 1991.A method of heat exchange comprises advancing energy-carrying medium in a channel system comprising channel-part lengths (1) which extend in side-by-side mutually parallel relationship, such as hose parts (1), and substantially sheet-like or slab-like base parts (2) which support the channel parts. The method is mainly characterized by supporting and holding channel parts (1) with the aid of at least one pre-fabricated sheet or slab (2) of heat-insulating material, such as so-called cellular plastic material, and by inserting the channel parts (1) into locking grooves (3, 4) included in the slab or sheet, the width of locking grooves, when appropriate, being preferably slightly smaller than the width of a channel part, in appropriate cases the diameter of the channel part. The invention also relates to an arrangement for carrying out the method.
