Counter Flow Heat Exchanger Diagram

Double pipe heat exchanger design requires use of the heat transfer rate the log mean temperature difference and an estimate of the overall heat transfer coefficient to calculate the estimated heat transfer surface area.

Counter flow heat exchanger diagram.

A heat exchanger can have several different flow patterns. A counterflow heat exchanger will require less heat exchange surface area than a parallel flow heat exchanger for the same heat transfer rate and the same inlet and outlet temperatures for the fluids. For example in a distillation column the vapors. The counter current design is the most efficient in that it can transfer.

There are three primary classifications of heat exchangers according to their flow arrangement. In a parallel flow exchanger both fluids in the heat exchanger flow in the same direction. A counter flow or countercurrent shell and tube heat exchanger s construction is in many ways identical to that of a parallel flow shell and tube heat exchanger. Crossflow parallel flow and counterflow heat exchanger configurations are three examples.

A double pipe heat exchanger consists of one pipe inside another. In parallel flow heat exchangers the two fluids enter the exchanger at the same end and travel in parallel to one another to the other side. For a parallel flow heat exchanger n 0 and for a counterflow heat exchanger n 1. The flowing bodies can be liquids gases or even solid powders or any combination of those.

The main difference is that the tubeside fluid enters the exchanger at the opposite end of the shellside fluid. The most common arrangements for flow paths within a heat exchanger are counter flow and parallel flow. In counter flow heat exchangers the fluids enter the exchanger from opposite ends. Shell and coil heat exchanger diagram spiral plate heat exchanger.

It is a form of a plate heat exchanger usually made of stainless steel. Counter flow shell and tube heat exchangers. A counter flow heat exchanger is one in which the direction of the flow of one of the working fluids is opposite to the direction to the flow of the other fluid. Consider a parallel flow or counterflow heat exchanger consisting of fluid 1 fluid 2 and the wall separating these two fluids.

It can be operated as a parallel flow or as a counterflow heat exchanger. Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering in which there is a crossover of some property usually heat or some chemical between two flowing bodies flowing in opposite directions to each other.
