    Detailed Product Description
    Material: Stainless Steel, SMO, Titanium, Etc. Core Structure Of Heat Exchange: Corrugated Metal Sheets To Be Welded As A Sheet Bundle
    Structure: Welded Plate Sheet Bundle Mounted Into A Block-type & Bolt-connected And Sealed Metal Frame Design: Customised
    Application: Oil & Gas, Refinery, Chemical Industries, Etc. Packing: Seaworthy Packing
    After-sale Service: Available Upon Request

    Block-type & Fully-welded Plate Heat Exchanger is a new product in the compact heat exchanger family.

    The plate bundle fully welded with plate sheets is mounted into a frame of 4 bolted side panels with a top plate and a base plate sustaining pressure. The side panels are provided with nozzles with fluid inlet and outlet.

    Due to the bolt-connected structure, the plates can be easily demounted for easy cleaning and maintenance of the plate bundle.

    The plate sheets are welded to each other without any gasket used, so it can be applied for high temperature & pressure applications.

    The corrugated profile of plate sheet causes heavy turbulence of the fluid, so the heat transfer coefficient is 2-4 times of conventional tube & shell heat exchanger. Under the same working condition, the required area for heat transfer is only 25-30% of conventional tube & shell heat exchanger.

     

    Work Principle / Flow

    Thin metal sheets are pressed to produce corrugated plates and then a stack of such corrugated plates are welded one another and thus form the block type & fully welded plate heat exchanger. Neighboring sheets establish narrow and tortuous channels in between and allow the working fluid to flow through. The cold fluid and hot fluid flow through its own channels in order. The cold and hot channels are separated by the sheet naturally, where heat exchange takes place.

    Attributable to the structure & working principle, this type of PHE is featured by compact structure, small footprint, high heat transfer efficiency, flexible operation, wide application, low heat loss, easy installation & cleaning, etc.

    Advantage

    1. High heat transfer coefficient – Under the same condition of pressure drop limit, the heat transfer coefficient is 2-4 times of tube & shell heat exchanger;
    2. Compact structure – Small size & quick response to control;
    3. Light weight – Reduced precious metal cost;
    4. Laser welded plate sheet bundle – High pressure & heat resistance;
    5. Turbulence can be caused even in case of low velocity. Low fouling due to the big shearing force on the sheet wall surface.
    6. Multiple flow may flow in opposite directions – The heat exchange efficiency can be greatly increased and close approach temperature is achieved;
    7. Even distribution of fluid – The heat transfer efficiency is increased and the flow resistance is decreased;
    8. Demountable side panels & visible welding seams at the core – Easy cleaning & maintenance;
    9. Rich experience of manufacturing – Safe & reliable products;
    10. Plenty of stocks on components – Reduced lead time;
    11. High management efficiency – Low cost on products.
