Abstract (en)
[origin: CA2654633A1] One of these heat exchangers (76) consists of a stack of thin-metal walle d hollow platelets (7S1-J5), 12 cm long and 5 wide. Each of these walls has a central region stiffened by alternating bosses with steep slopes, situated between two connection regions. Each wall is made by pressing then cutting an appropriate sheet of metal (aluminium 0.3 mm thick). The edges of the two fin walls form steps, symmetrically welded, the height of each step determi ning the internal half-thickness of a fin. Each platelet connection region e nds in a narrow mouth with a cross section that has the same surface area as the embossed central region, and is welded to the edges of a slot made in a n external manifold (80-82). The thickness of the internal channel of a plat elet is about 0.4 mm when the fluid concerned is a liquid (water) and that o f the spaces between the platelets is 7 mm when the other fluid is a gas (ai r). By hot pressing or thermoforming, sheets of glass or polymer may also be used but the performance is reduced.
