摘要：PCT No. PCT/AU88/00159 Sec. 371 Date Jan. 2, 1990 Sec. 102(e) Date Jan. 2, 1990 PCT Filed May 25, 1988 PCT Pub. No. WO88/09261 PCT Pub. Date Dec. 1, 1988.This invention relates to an improved method of manufacturing a heat exchanger element. In a second aspect the invention concerns a heat exchanger element itself. In the third aspect the invention concerns a reservoir suitable for housing the heat exchanger element to form a heat exchanger. The element is manufactured by extruding polyethylene tubes and winding them into spiral coils. Each coil is located along the length of a rigid horizontal spacer bar in order to maintain even spacing of the coil. The element comprises a stack of coils which are not restrained against vertical movement. The element also comprises a cylindrical void through the center.
