Coolant Manifolds for commercial vehicles

Coolant Manifolds for Electric Vehicles and other applications


As the automotive industry increasingly shifts towards electrification, thermal energy management becomes essential for ensuring optimal performance and longevity of various components. Coolant manifolds are paramount in this thermal management system, enabling coolant distribution to multiple vehicle parts.

Flow distribution is a key consideration in the design and operation of coolant systems, particularly in EVs, where a single pump may be responsible for circulating coolant to various components, such as the battery pack, electric motor, power electronics, and thermal management systems.

Each of these components operates under different conditions and has unique thermal requirements. For instance, the battery pack may require a consistent and controlled temperature to maintain efficiency and safety. At the same time, the electric motor may experience varying thermal loads depending on driving conditions and performance demands. Coolant manifolds allow for precise flow distribution.

How we design effective coolant manifolds


Technical Services specialises in designing effective coolant manifolds to ensure each component receives the appropriate amount of coolant. Manifolds are crucial in preventing overheating and ensuring the safety and optimal performance of the components. Our design team meticulously considers every factor, such as the geometry of the manifold, the placement of inlets and outlets and the overall flow path of the coolant.

At Technical Services, we understand the dynamic nature of EV operation and the thermal demands of components, which fluctuate significantly. Our manifold range can be enhanced by combining valve and manifold technology to respond to changes in driving conditions by automatically adjusting the coolant flow to maintain the required thermal balance across all components. This adaptability ensures the overall efficiency and reliability of EV and contributes to reducing energy consumption, preventing localised overheating, ensuring uniform cooling and providing longevity for critical components.

Introducing our range

Technical Services’ range of standard manifolds for EV is available in 3 – 6 channels, which our design team can configure to manage flow distribution with barb and orifice diameters. Using a powerful 3D model and 1D tool, we can pre-configure manifolds ‘ready to fit’ as part of your overall thermal management solution.
