power engineering. SUBSTANCE: thermal apparatus has casing and vertical banks of parallel heat exchange elements made in form of spatially spiral coils with similar geometric characteristics forming separate hexahedral modules arranged in unit; turns of coils are brought between turns of adjacent coils both in bank and between turns of adjacent banks before they get in contact; distance between centers of modules "H" is determined from the following formula , where "T" is center-to-center distance of heat exchange elements; "n" is number of rows in hexahedral module located around central element. EFFECT: enhanced reliability and efficiency of heat exchange apparatus working on various heat-transfer agents. 4 cl, 5 dwg |
