Pressure cycling test bench for climate components

Efficient endurance tests for heating and cooling systems

For thermal management in vehicles – be it with electric or combustion drive - cooling and heating systems are essential: they protect against overheating and provide comfort. To facilitate and accelerate lifetime tests, Poppe + Potthoff Maschinenbau has developed a novel testing system.

The pressure cycling test bench simulates the drive operation for the test specimen by means of freely programmable temperature, volume flow and pressure changes in sinusoidal and trapezoidal form. The temperature of test medium (water-glycol mix or 100% glycol) can vary from -40 to +140 degrees Celsius.

A specially developed closed test medium circuit thereby prevents the generation of alcoholic vapors (risk of explosion) by means of pressure. An additional climate chamber can optionally be used to generate the environmental simulation. In a test frequency of 0.2 to 1 Hz the flow rate of the test medium can vary from 3 to 30 l/min at a pressure of 0.2 to 10 bar (max. 12 bar).

With the testing unit, complete systems as well as individual components made of various plastics, metals and sealants can be tested. With the help of realistic simulation, the weak points in the bonded material are precisely and economically determined – for example, in the area of a welding seam – and can be optimized early on during the development process.
