Logarithmic average temperature difference large



  • Is a series of plate heat exchanger with corrugated metal stack of the shape must fit into a new high-efficiency heat exchanger. Formed between various plate thin rectangular channel, heat exchange by halves. Plate heat exchangers are heat exchange liquid-liquid, liquid-gas the ideal equipment. It has a high heat transfer efficiency, heat loss, compact lightweight, small footprint, easy installation and cleaning, apply a broad, long life and other characteristics. Under the same pressure loss, its 3-5 times higher than tube type heat exchanger of heat transfer coefficient, one-third covers an area of tubular heat exchanger, heat recovery rate can be as high as 90%.
    This balance of complete sets of equipment consists of a plate heat exchanger, tank, centrifugal pump, hot water installations (including steam pipes, hot water is injected into the collector), bracket and meter boxes, and other components. For sterilization and cooling of milk or other heat sensitive liquids. Processing of materials into the balance tank, centrifugal pump into after preheating, sterilization, thermal insulation, heat exchangers, cooling, where the material does not meet the sterilization temperature, controlled by the instrument balance Groove of air reflux valve, and then back to back. Sterilization temperature is controlled by the instrument box for automatic control of material and continuous recording, so that the sterilization process is monitored and checked. This equipment is used in milk sterilization, BA-sterilization. Plate heat exchanger plate heat exchangers of type main frame (removable) and solder in two categories, corrugated plate, horizontal plate forms the main glyph shape and three flat corrugated board, and tumor.
    A. high heat transfer coefficient due to a variety of corrugated plate upside down, constitute a complex flow, fluid flow between the corrugated board is rotated in three-dimensional flow at low Reynolds numbers (Re=50~200) under turbulent flow, so the high heat transfer coefficient, is generally considered 3~5 of shell-and-tube times.

    In world economic recession of situation Xia, many China enterprise in for mass of transformation, from traditional market development transformation to Internet network development, in comparison single B2B platform in the select more of promotion way, many jaw crusher and grinding-mill manufacturers enterprise in industry competition very fierce of situation Xia, select has more platform and more website of promotion mode to for promotion publicity, made has very good of effect.
    Printing industry is the same, some string tag and hang tag under the situation of dealers in the global market is in the doldrums, more precise market targeting, such as in the United States jewelry cards and the price tag the market is very good, but also to the survival of many foreign trade companies and many opportunities.

    But the wedding dresses are not the same, traditional wedding there is no brand leading product promotion manufacturing is very difficult, but some of the big brand companies wedding dress market is very good, such as: wedding dress Anjolique,wedding dress of Bonny which brands are selling very well.

    However these industries so fierce competition in the market, there is a market still very stable, it is the tattoo machines , many tattoo supply are wondering why their market is not affected by the global economic shocks

    B. logarithmic average temperature difference large, end temperature difference small in tube shell type heat exchanger in the, two species fluid respectively in tube pass and shell range within flow, General Shang is wrong flow flow, logarithmic average temperature difference amendment coefficient small, and plate heat exchanger more is and flow or counter flow way, its amendment coefficient also usually in 0.95 around, also, cold, and hot fluid in plate heat exchanger within of flow parallel Yu for hot surface, and no next flow, so makes plate heat exchanger of end temperature difference small, on water for hot can below 1 ℃, and tube shell type heat exchanger General for 5 ℃.
