Optimization of heat exchanger

The design and geometry of heat exchanger has not only a major influence on performance but on development cost for casting. Evaluation of optimal geometry by using CFD technology improves product performance and creates sales advantages.

Let's take a look at a CFD simulation of two versions of a heat exchanger for charge air. It should cool down a certain mass flow rate at 50 °C and below and achieve about 100 kW cooling power. Lets assume the same cooling mesh for two different inlet and outlet geometries. The CFD results below show a significant improvement of performance due to geometry optimization.

Version 1

Stream lines with temperature distribution

Suboptimal geometry

Due to the suboptimal geometry a major part of the heat exchanger has an inefficient flow circulation. The cooling power is 11% less than it should be and the requirement for the outlet temperature is not met.

Version 2

Stream lines with temperature distribution

Optimal geometry

After several design steps the right geometry was evaluated with a full developed flow circulation so that the required performance and outlet temperature are achieved.
