High-Efficiency Liquid-Cooled Condenser– A Compact Heat Exchange Solution for Electric Passenger Vehicles

As the demand for thermal management in electric vehicles continues to rise, traditional air-cooled solutions are being replaced by more efficient and compact liquid-cooled systems. The Liquid-Cooled Condenser (LCC) plays a key role in ensuring optimal refrigerant condensation, enhancing overall system efficiency. This article introduces a high-performance, plate-fin type LCC specifically designed for passenger vehicle applications, offering outstanding thermal performance in a compact and reliable form.

Key Performance Benefits of Guchen Liquid-cooled Condenser

High efficiency in a compact form: The plate-fin structure ensures excellent thermal performance even in space-constrained applications. Lightweight and space-saving: The small footprint (170×70×80 mm) makes integration into passenger car platforms easier.

Cost-effective: Optimized for mass production using mature brazing techniques. Reliable and durable: Capable of withstanding burst pressures >9 MPa and meeting international leak standards.

Modular design: Customizable flow paths and layouts to meet specific OEM requirements. Superior pressure resistance: Fully brazed construction reduces weak points found in traditional welding.

Design and Construction of EV Liquid-cooled Condenser

This LCC features a plate-fin heat exchanger structure that utilizes a stacked configuration of aluminum plates and fins. The high-temperature gaseous refrigerant flows through dedicated channels formed between the plates, while coolant flows through alternating channels, allowing efficient heat exchange across the thin walls.
The plate thickness ranges from 0.5 to 1.0 mm, balancing structural integrity with weight reduction. The flow paths can be configured as single-pass or multi-pass to optimize refrigerant and coolant distribution. This flexibility allows the unit to be tailored for various installation constraints and thermal performance requirements.
For manufacturing, the condenser employs pre-coated brazing sheets and undergoes controlled brazing in a NOCOLOK® brazing furnace. This process fuses plates and fins into a single compact unit, ensuring excellent sealing and mechanical strength without residual flux or welding slag.

Common Questions & Answers

What is the helium leak test pressure?

The typical helium test pressure is 2.5 MPa on the refrigerant side and 0.25 MPa on the coolant side, though these values can be customized based on client requirements.

How is stacking accuracy ensured during production?

The assembly process utilizes automated image recognition systems to identify and align each plate, supplemented by weight verification checks to detect potential assembly errors. This ensures consistent product quality and reliable heat exchanger performance.
