Automotive Radiator‑Type Liquid Cooling Plate

I. Product Overview

The automotive radiator‑type liquid cooling plate is a high‑end integrated core component in the thermal management system of new energy vehicles. It combines the dual advantages of a traditional liquid cooling plate and a cooling radiator, adopting a structure of “radiator‑style dense flow channels + integrated sealed cavity”. By integrating built‑in dense heat dissipation fins with multi‑branch flow channels and matching coolant circulation, it efficiently dissipates heat generated by core components such as battery packs, motors, and motor controllers.

Different from conventional cavity cooling plates and dual‑inlet dual‑outlet cooling plates, this product features a large heat dissipation area, high heat exchange efficiency, wide adaptability, and easy installation. It perfectly meets the full‑domain temperature control requirements of various new energy vehicles, handling both high heat flux scenarios in high‑power fast charging and stable heat dissipation during normal driving. As an optimal solution to ensure safe all‑condition operation, extended driving range, and prolonged service life of core components in new energy vehicles, it is widely used in passenger vehicles, commercial vehicles, energy storage systems, and special vehicles.

II. Core Selling Points (Concise Version)

Integrated radiator design doubles heat exchange efficiency

Built‑in dense heat dissipation fins and multi‑branch flow channels greatly expand the heat exchange area (40%–60% larger than conventional cavity cooling plates). Heat exchange efficiency is 35%–55% higher than traditional cooling plates and 15% higher than dual‑inlet dual‑outlet cooling plates. Battery pack temperature difference ≤2℃, compatible with 6C–8C ultra‑fast charging, quickly removing high heat flux and eliminating high‑temperature power limitation and local hotspots.
Compact structure with superior lightweight performance

Integrated design of radiator and cooling plate eliminates the need for an external cooling radiator, resulting in a more compact structure that saves over 30% of vehicle installation space. Made of 6061 aluminum alloy, it is over 40% lighter than copper cooling plates and over 25% lighter than conventional radiator + cooling plate combinations, supporting vehicle lightweighting and indirectly improving driving range.
Full‑domain adaptability and reliable automotive‑grade quality

Meets both high heat flux and conventional heat dissipation needs, with wide temperature adaptability from ‑40℃ to 120℃, no freezing blockage or deformation. Manufactured via vacuum brazing / FSW solid‑state welding for zero leakage (helium leak rate ≤1×10⁻⁹ mbar·L/s), salt spray and corrosion resistance. It has passed automotive‑grade vibration (20g) and impact (50g) tests, with a service life of ≥10 years, suitable for complex road conditions and all‑weather operation.
Flexible adaptation and convenient, efficient installation

Customizable flow channels (serpentine / parallel / in-line), fin density, and dimensions. Compatible with CTC / CTB integrated solutions and commercial vehicle 3‑in‑1 thermal management systems, covering models from A00‑class to heavy‑duty commercial vehicles. The integrated design reduces the number of parts, simplifies installation steps by 40%, and lowers assembly and maintenance costs.
Controllable mass production and excellent full‑life‑cycle cost‑effectiveness

Mass production yield ≥98%, cost over 30% lower than “conventional cooling plate + independent radiator” combinations and over 25% lower than microchannel cooling plates. Extends battery and core component life by over 20%, reduces failure and maintenance costs, lowers full‑life‑cycle TCO by over 15%, and supports large‑scale mass production.

IV. Typical Application Scenarios

New energy passenger vehicles: Bottom cooling for battery packs in long‑range, high‑power fast‑charging BEV / PHEV models, compatible with CTC / CTB integrated body design, saving installation space, improving range stability, and efficiently handling high heat flux.
Commercial vehicles / heavy trucks: 3‑in‑1 thermal management for power batteries, motors, and electronic controls. The radiator‑style structure adapts to high‑load operation, quickly removing simultaneous heat from multiple components, ensuring stable thermal management under complex road conditions and high‑power fast charging.
Energy storage systems: Temperature control for battery packs in industrial and commercial energy storage containers. Dense fins + multi‑branch flow channels improve heat dissipation efficiency, supporting high‑power charging and discharging and ensuring safe, stable operation without local overheating.
Special vehicles: Battery cooling for construction machinery and logistics vehicles. The integrated radiator structure is vibration and impact resistant, adapting to high/low temperatures and harsh conditions with low risk of fin detachment, extending service life.

V. Selection and Installation Guidelines

Power matching: For 100–200 kWh battery packs, select 10–25 kW radiator‑type liquid cooling plates; for 200 kWh and above, use 25–35 kW units. Choose fin density based on vehicle power and heat dissipation requirements.
Flow channel and port selection: Fast‑charging models prefer dual‑inlet dual‑outlet + parallel multi‑branch channels (low pressure drop, high flow compatible); conventional models may use single‑inlet single‑outlet + serpentine channels (high heat exchange, uniform temperature control).
Installation requirements: Ensure cooling plate flatness ≤0.05 mm, attach with thermal grease or phase change materials, and fasten bolts evenly to avoid cavity deformation or fin detachment caused by local stress. Match ports to vehicle thermal management pipelines and ensure sealed connections.
Medium requirements: Use 50% ethylene glycol + 50% deionized water (conductivity <1 μS/cm). Replace coolant every 12 months to prevent scaling that clogs flow channels and adheres to fins, reducing heat exchange efficiency. Inspect fin integrity regularly.
