Abstract (en)
[origin: EP0537650A2] Heat exchangers of high performance and high hygiene levels are produced from steel and galvanised. It has been found that a more stable and resistant structure is achieved by constructing the heat-transferring ribs by means not of plates, but of sheets 19 to 21, 23 to 25 arranged in a multiplicity of rows. The alternating use of sheets of different width permits different dividing spacings of the sheets to be achieved in the direction of passage of the air to be cooled, without the need arising for a corresponding number of gaps acting as balancing zones. Due to the elimination or substantial reduction of the number of gaps, the latter can be held so wide without essential impairment of the thermal performance that metal bridges are avoided in the case of galvanisation and the settling of foreign bodies which impair hygiene is suppressed during operation. <IMAGE>
