Plate heat exchangers were first introduced in 1923 for milk pasteurization applications, but are now used in many applications in the chemical, petroleum, HVAC, refrigeration, dairy,
May 01, 2012 · This paper presents the application of imperialist competitive algorithm (ICA) for optimization of a cross-flow plate fin heat exchanger. Minimization of total weight and total annual cost are considered as objectives. Seven design parameters, namely, heat exchanger length at hot and cold sides, fin height, fin frequency, fin thickness, fin-strip length and number of hot side layers are China Design and Applications of Plate Fin Heat Exchangers The corrugation of the plates provides the passage between the plates, supports each plate against the adjacent one and enhances the turbulence, resulting in efficient heat transfer. Standard Design Plate heat exchanger consists of a pack of corrugated metal plates with portholes for passage of the two fluids between which heat transfer will take place.
Jun 01, 2016 · Heat exchangers are used to transfer thermal energy between two or more media and be known as one of the most essential equipment in almost every industrial plant, including power engineering, aerospace, electronics, automobile, petroleum refineries, cryogenic and chemical industries, etc. Plate-fin heat exchanges (PFHEs) are widely used in gasgas applications for their high Optimisation of Plate/Plate-Fin Heat Exchanger DesignFor plate heat exchangers, the design methodology is developed on the basis of plate-fin heat exchanger methodology, and takes phase change, plate pattern selection, flow arrangement and pressure drop constraints simultaneously. The phase change problem is
Sep 16, 2018 · Plate heat exchanger applications. In this article well be discussing the application of plate heat exchangers. Looking at the different types from gasket type, brazed plate type, welded type and micro plate type as well as their applications such as chillers, heat pumps, HVAC, industrial, district energy, heat interface units etc. Plate Heat Exchanger Design GranoWorking Principle. Channels are formed between the plates and the corner ports are arranged so that two media flow through alternate channels. The heat is transferred through the plate between the channels, and complete counter-current flow is created for the highest possible efficiency. The corrugation of the plates provides the passage between the plates, supports each plate against the adjacent one and enhances the turbulence, resulting in efficient heat
May 25, 2018 · Plate-Fin Heat Exchangers (PFHEs), which are widely used in air separation, natural gas liquefaction process, aerospace, automobile and so on, are characterized by compactness (up to 10002500m2 /m 3) and high thermal efficiency. A PFHE is typical assembled from a series of parting sheets and layers of fins in a sandwich manner. Thermal design and optimization of plate-fin heat Morris and Sobol global sensitivity analyses are firstly studied to evaluate the effects of the design parameters on the performance of plate-fin heat exchanger with serrated fins. Five design parameters such as the fin height, fin space, fin thickness and interrupted length and channel Reynolds number are selected as optimization parameters. Heat flow rate, total annual cost and entropy generation number
Applications Plate-fin and tube-fin heat exchangers have found application in a wide variety of industries. Among them are air separation (production of oxygen, nitrogen and argon by low temperature distillation of air), petro-chemical and syn-gas production, helium and hydrogen liquefiers, oil and gas
