Publication number: 20100012303Abstract: One of these heat exchangers (76) consists of a stack of thin-metal walled 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 determining the internal half-thickness of a fin. Each platelet connection region ends 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 an external manifold (80-82). The thickness of the internal channel of a platelet is about 0.4 mm when the fluid concerned is a liquid (water) and that of the spaces between the platelets is 7 mm when the other fluid is a gas (air).Type: ApplicationFiled: June 12, 2007Publication date: January 21, 2010Inventor: Jean-Paul Domen

Patent number: 7648686Abstract: A catalytic reactor including a heat exchanger and a method are provided for transferring heat to a coolant and a reaction fluid. The catalytic reactor includes a reaction fluid flow path, a reaction region, and a coolant flow path. A reaction fluid catalytically reacts at a surface area in the reaction region thereby generating heat. The heat is transferred to a coolant and the reaction fluid based on the coolant and reaction fluid convective heat transfer coefficients respectively. In one embodiment, the ratio of the coolant convective heat transfer coefficient to the reaction fluid heat transfer coefficient is at least 5:1.Type: GrantFiled: April 5, 2004Date of Patent: January 19, 2010Assignee: Modine Manufacturing CompanyInventors: Michael J.

Patent number: 7624790Abstract: Desalination apparatus based on porous restraint panels fabricated from a number of different layers of metal, thermoplastic, or other substances are used as sophisticated heat exchangers to control the growth of gas hydrate. The gas hydrate is produced after infusion of liquid hydrate-forming material into water to be treated, which liquid hydrate-forming material can also be used to carry out all the refrigeration necessary to cool seawater to near the point of hydrate formation and to cool the porous restraint panels. Hydrate forms on and dissociates through the porous restraints. The composite restraint panels can also be used in gaseous atmospheres where, for instance, it is desired to remove dissolved water.Type: GrantFiled: June 23, 2008Date of Patent: December 1, 2009Assignee: Marine Desalination Systems, LLCInventor: Michael David Max
