Custom CNC Machined EV Battery Cooling Plate

Liquid cooling plates are key components in EV thermal management systems, used to dissipate heat from high-power applications.

Our products are designed for a wide range of EV systems, including battery packs, e-drive units and power electronics such as PDU, OBC and DC/DC converters. 

With optimized internal channel design and reliable sealing, our cooling plates ensure efficient heat transfer, uniform temperature distribution and stable system performance.

Features

Our liquid cooling plates are suitable for battery, e-drive and power electronics applications, providing high heat transfer efficiency and low pressure drop. The structure is designed to be leak-proof and lightweight by using aluminum materials. All products are fully customizable to meet different structural and performance requirements.

Technical Specifications Inlet temperature: ≤ 65°C Flow rate: ≥ 21 L/min Pressure drop: ≤ 30 kPa Internal volume: ~0.8 L Custom specifications are available upon request.

Applications

The products are widely used in EV battery thermal management, e-drive systems (3-in-1 / 4-in-1), power distribution units (PDU), on-board chargers (OBC), DC/DC converters and energy storage systems (ESS).
