Product Overview of Guchen Battery Chiller

The battery chiller is a critical component in electric vehicle (EV) battery thermal management systems. Designed to maintain optimal battery operating temperatures, it efficiently dissipates heat generated during battery operation, thereby extending battery life and ensuring safety. Our battery chiller offers a cooling capacity ranging from 6 to 18 kW and uses environmentally friendly refrigerants such as R134a or R1234yf. The compact unit measures 130 mm × 60 mm × 150 mm, with height customizable according to customer requirements, and is constructed from durable aluminum alloy to ensure lightweight strength and corrosion resistance. It is primarily designed for passenger vehicles.

Factors Influencing Battery Chiller Performance

Cooling Method: Liquid cooling generally outperforms air cooling due to higher heat capacity, while immersion and refrigerant direct cooling offer superior uniformity and efficiency.

Flow Channel Design: Optimized flow channels ensure even coolant distribution, avoiding hotspots and cold spots.

Heat Exchanger Design: Effective heat exchangers feature large surface areas, excellent thermal conductivity, and well-designed fluid flow paths to maximize heat transfer between coolant and battery.

Structural Features and Parameters of Liquid-cooled Battery Chiller

Compact Design: To fit the limited space in EV battery compartments, the chiller adopts a flat and streamlined form factor, minimizing spatial footprint.
Multi-Channel Flow: Multiple cooling channels ensure uniform coolant distribution, providing consistent cooling across all battery modules and reducing temperature gradients.
High Sealing Integrity: Customized sealing solutions, including sealing rings and welding, prevent coolant leakage and protect battery cells and adjacent components.
Strong Battery Pack Compatibility: The chiller is tailored to the shape, size, and arrangement of the battery pack for optimal thermal contact and integration.
High Integration Level: Some models integrate additional features such as heating elements for temperature regulation in cold environments and sensor mounts for real-time monitoring of temperature and pressure.

Connection Method

The coolant pipes of the battery cooler are connected to the cooling plates of the battery modules, forming a closed-loop system. The battery cooler removes heat from the coolant through these pipes, which then passes through a heat exchanger (like a radiator) to release heat to the external environment, maintaining the battery at an optimal temperature.
