PCT No. PCT/AU80/00014 Sec. 371 Date Jan. 17, 1981 Sec. 102(e) Date Jan. 6, 1981 PCT Filed May 16, 1980 PCT Pub. No. WO80/02590 PCT Pub. Date Nov. 27, 1980.A heat exchanger module, such as a solar collector module, comprising a tube sheet (3) connected to a header (4). The tube sheet (3) passes through an opening in the header (4) so that the end of the sheet (5) protrudes a distance into the header (4), the header opening being united to the surface of the tube sheet (3) so that the tendency of the tube sheet (3) to burst or split open in the region of the junction of the tube sheet and header is minimized when the module is under fluid pressure. By the term "tube sheet" is meant a substantially planar sheet having an upper and a lower plastic membrane interconnected by a series of spaced division walls thereby forming a series of tubes arranged generally in a flat plane across the sheet, the tubes being continuous through the sheet and open at the two opposite ends of the sheet. The term also includes a sheet of circular tubes joined in side-by-side relationship.
