CLASSIFICATION OF HEAT EXCHANGERS

Classification of heat exchangers

• The heat exchanger is classified on the basis of the following criteria

1. According to flow arrangements of fluid
2. According to construction
3. According to the heat transfer process

Classification of the Heat exchanger according to flow arrangements of fluid

1. Parallel flow heat exchanger
2. Counterflow heat exchanger
3. Crossflow heat exchanger

Classification of the Heat exchanger according to construction

•  Tubular heat exchangers
1. Shell-and tube heat exchangers
2. Double-pipe heat exchangers
3. Spiral tube heat exchangers

• Plate-type heat exchangers
• Extended surface heat exchangers
• Regenerative heat exchangers

Classification of the Heat exchanger according to the heat transfer process

1. Direct contact type or mixers
2. Transfer type or Recuperators
3. Storage type or Regenerative
