  2. Compact Heat Exchanger A type of heat exchanger which is specifically designed to realize the larger heat transfer area per unit volume. A heat exchanger with β>700m2/m3 is classified as being compact heat exchanger, e.g. Car radiator(β≈1000m2/m3) Gas ceramic gas turbine heat exchanger(β≈6000m2/m3) Human lung(β≈20,000m2/m3) engineering-resource.com

  3. Characteristics of Compact Heat Exchanger • Large extended surfaces. • High β>700m2/m3(200ft2/ft3) • Small hydraulic diameter. • Usually at least one of the fluid is gas. • Fluid must be clean. engineering-resource.com

  4. Types of Compact Heat Exchangers • Tubular heat exchanger • Fin-plate heat exchanger • Tube-fin heat exchanger • Plate-frame heat exchanger • Regenerative heat exchanger engineering-resource.com

  5. Tubular heat exchanger:- • Flow pattern: cross flow • Fluids: Gas-liquid • Construction: engineering-resource.com

  6. Tube-fin heat exchanger:- • Flow pattern: cross flow, counter flow • Fluids:Gas-liquid • Construction Spiral HE Longitudnal HE engineering-resource.com

  7. Regenerative heat exchanger:- • Flow pattern: Alternative flow pattern • Fluids: Gas-Gas • Construction: A matrix engineering-resource.com

  8. Plate-frame heat exchanger:- • Flow pattern: Counter flow • Fluids: Liquid-liquid • construction engineering-resource.com

  9. PLATE-FRAME HEAT EXCHANGER engineering-resource.com

  10. Parts of Plate-Frame Heat Exchanger:- • Fixed frame • Plates • Gasket • Pressure plate • Carrier bars engineering-resource.com

  11. Material of construction: engineering-resource.com

  14. ADVANTAGES: • High performance heat exchanger plates. • Very high heat transfer coefficients due to best utilization of surfaces. • Compact and low price solutions. • Easy installation and maintenance. • Flexibility to add/remove plates for higher/lower capacity requirements. • Much less space than shell & tube exchanger. engineering-resource.com

  15. APPLICATION AREAS: • In car radiators. • Tank heating for various processes in industry. • Applications in chemical, pharma-ceutical and food processing systems. • Exchange and recovery of heat in industrial plants. • Heating and production of hot domestic water from solar panels. • Pasteurization of beverages. • Air conditioning systems. • Cooling of industrial oils, cooling circuit of machinary. engineering-resource.com

  16. COMPARANCE WITH SHELL TUBE HEAT EXCHANGER: • They occupy 80% less space as compared shell and tube heat exchanger. • Overall Heat transfer coefficient is three or four times higher as compared to shall and tube heat exchanger. • Low pressure and low temperature devices. engineering-resource.com

  17. LIMITATIONS: • Max. Design Pressure: 25 Bar • Max. Design Temperature: 200°C • It is only used for clean fluids. engineering-resource.com
