Thermal management for electric mobility & laboratory technology

In various development projects, significant experience has been gained in the field of cooling plates, in particular for battery cooling and inverter cooling. Different geometries and design principles were implemented.

We are currently developing a modular system with staggered sizes in order to be able to react quickly and cost-effectively to customer requirements. The range of applications is very diverse, from automotive to computer technology, gastronomy, laboratory technology, medicine, process technology, rail vehicles to inverters …

Within the framework of the qOpt research project of the Forschungsgesellschaft Kraftfahrwesen Aachen (fka) as consortium leader and with HAUGG as industrial partner, the model of a latent heat storage system was developed and tested.

The aim of the project is the development of a latent heat storage system in combination with an intelligent operating strategy for waste heat recovery. Several advantages:

• Range increase of an electric vehicle
• Storage of the lost energy and subsequent demand-based supply
• Increasing the overall efficiency of an electric vehicle.

As part of the KERME research project, HAUGG, as an industrial partner, designed the cooling circuit for an electric motor developed at Aachen University and supplied the components. The project partners were the WZL (Machine Tool Laboratory) and the IEM (Institute for Electrical Machines) of RWTH Aachen University. The goal of the project was the development of a scalable and modular electric motor for different power levels with an optimised cooling circuit.

In all power electronics, heat means a loss of power. In order to optimise these losses, active cooling is the best solution.

Experiences from Formula Student applications first brought concrete measured values, which were subsequently verified.

The fields of application are manifold, so that we gain knowledge with every new project.
