What are the classifications of heat exchangers?

What are the classifications of heat exchangers?

Furthermore, as stated below heat exchangers can be classified according to its construction as stated below.

  • Shell and tube heat exchangers.
  • Plate type heat exchangers.
  • Spiral heat exchangers.
  • Double pipe heat exchangers.
  • Air cooler heat exchangers.

What will affect the heat transfer rate in heat exchangers?

Heat transfer performance of heat pipe heat exchanger affected by many factors, such as the opening temperature of the heat pipe, the rate of fluid-filled, the physical nature of liquid refrigerant, the work temperature of tube, angle, tube spacing, tube length, hot and cold fluid flow and wind speed.

How can you increase the rate of heat transfer?

If the temperature difference on opposite sides of the material through which heat is transferred is increased by a factor of 2, then the rate of heat transfer is increased by a factor of 2.

Which heat exchanger is most efficient?

Plate exchanger is the most efficient due to turbulent flow on both sides. High heat-transfer coefficient and high turbulence due to even flow distribution are important. However, a plate heat exchanger regenerator is restricted to low viscosities.

Which type of heat exchanger is more efficient?

The plate type heat exchanger is the most efficient type of heat exchanger with its low cost, flexibility, easy maintenance, and high thermal transfer. WCR plate corrugations are designed to achieve turbulence across the entire heat transfer area. This produces the highest possible heat transfer coefficients…

What information is needed to size a heat exchanger?

The minimum information needed to size the heat exchanger for both the hot and cold sides are: fluid names, flow rates, inlet temperature, outlet temperature, operating pressures and maximum pressure drop allowed across the unit.

What are the different types of heat exchanger?

Several types of heat exchangers are used for heating one fluid and cooling another. The types of heat exchangers include the shell and tube heat exchanger, plate heat exchanger, double pipe heat exchanger, and spiral heat exchanger. Most of these heat exchangers can be counterflow or parallel flow.

What are the advantages of a heat exchanger?

The Advantages & Disadvantages of Heat Exchangers Adaptable. Many modern heat exchangers, such as the plate heat exchanger, are very adaptable, which makes them suited for a wide variety of tasks. Cost and Maintenance. The fabrication costs of heat exchangers have fallen as technology has progressed. Industrial Applications. Leakage and Pressure.
