A heat transfer system is disclosed that includes a heat transfer fluid circulation loop, and also a heat exchanger that includes an aluminum alloy exterior surface having thereon a top surface coat derived from a composition comprising a trivalent chromium salt and an alkali metal hexafluorozirconate.

Aluminum heat exchanger

A heat exchanger is disclosed. The heat exchanger includes a hollow tube extending from a tube inlet to a tube outlet. The hollow tube includes a wall that includes a core of a first aluminum alloy, and a cladding over the core of a second aluminum alloy. The second aluminum alloy is less noble than the first aluminum alloy and includes an alloying element selected from tin, indium, or gallium, or combinations thereof. A first fluid flow path is disposed along an inner surface of the wall from the tube inlet to the tube outlet, and a second fluid flow path is disposed across an outer surface of the wall.

Heat exchanger with aluminum alloy clad tube and method of manufacture

A heat transfer system is disclosed that includes a heat exchanger comprising an inlet, an outlet, and a flow path through the heat exchanger between the inlet and the outlet. The system also includes a fluid circulation loop external to the heat exchanger connecting the outlet to the inlet. A phase change composition is disposed in the system flowing through the fluid circulation loop and the flow path through the heat exchanger. This the phase change composition includes a first PCM that is a plant or animal or paraffinic oil having a first melting point and a second PCM that is a plant or animal or paraffinic oil having a second melting point lower than the first melting point.

Heat transfer system with phase change composition

A method of measuring concentrations of gas mixtures is disclosed in which an ionic liquid and/or low vapor-pressure organic solvent is exposed to a gas mixture being tested to form a solution of the gas components in the liquid. The vapor pressure of the solution is then measured at one or more other temperatures and compared to predicted vapor pressures based on known individual vapor pressure profiles of the gas components in the liquid in order to determine the actual proportions of the components in the gas sample.

Method of measuring concentrations of gas mixtures

A method for coating an aluminum alloy heat exchanger includes subjecting at least one surface of the heat exchanger to a pre-treatment process including cleaning; conversion coating the at least one surface of the heat exchanger with a trivalent chromium compound; and subjecting the at least one conversion coated surface to an electro-coating in an aqueous solution containing an organic corrosion inhibitor.
