- Classification of heat exchangers: 1. Classification according to construction: Tubular heat exchangers. Plate heat exchangers. Extended surface heat exchangers.
- Materials for heat exchanger: 1. Aluminum 2. Stainless steel 3. Copper.
- Pipe in pipe heat exchangers: Hairpin heat exchangers (often also referred to as “double pipes”) are characterized by a construction form which imparts a U shaped appearance to the heat exchanger.
- Plate type heat exchanger. Construction and working of Plate type heat exchanger. It consists of a series of closely spaced parallel plates with fins held in between.
- Countercurrent flow. In cocurrent flow heat exchangers, the streams flow parallel to each other and in the same direction as shown in Figure 2, This is less efficient than countercurrent flow but does provide more uniform wall temperatures.
- Cocurrent flow. Crossflow heat exchangers are intermediate in efficiency between countercurrent flow and parallel flow exchangers. In these units, the streams flow at right angles to each other as shown in Figure 3.
- Crossflow. In industrial heat exchangers, hybrids of the above flow types are often found. Examples of these are combined crossflow/counterflow heat exchangers and multi pass flow heat exchangers.
- Cross/counter flow.
