—— Exclusive Liquid Cooling Solution for High Heat Flux in New Energy Vehicles, Dual-Circulation Enables Efficient Temperature Control and Safe Range
I. Product Overview
The automotive dual-inlet dual-outlet liquid cooling plate is an upgraded core thermal management component specially designed for high heat flux scenarios in new energy vehicles. Based on an integrated sealed cavity structure, it innovatively adopts a dual-circulation design with dual inlets and dual outlets. The built-in flow channels are integrated and divided into two independent loops. Through simultaneous circulation of dual coolant circuits, it efficiently regulates the temperature of core components such as battery packs, motors, and motor controllers.
Different from traditional single-inlet single-outlet and conventional cavity cooling plates, this product combines the advantages of dual-circuit temperature control flexibility, high heat dissipation efficiency, structural stability, and lightweight design. It perfectly meets the demands of high-power fast-charging, long-range passenger vehicles, and high-load commercial vehicles. As a high-end solution to ensure safe all-condition operation, extended driving range, and prolonged service life of core components in new energy vehicles, it is widely applicable to passenger vehicles, commercial vehicles, energy storage systems, and special vehicles.
II. Core Selling Points (Concise Version)
Dual-circulation for more efficient and uniform temperature control
Featuring independent dual-inlet dual-outlet loops for split-flow heat dissipation and synchronous temperature control, heat exchange efficiency is 30%–50% higher than traditional single-inlet single-outlet cooling plates and 20% higher than conventional cavity cooling plates. Battery pack temperature difference ≤2℃, compatible with 6C–8C ultra-fast charging, completely eliminating high-temperature power limitation and local hotspots, fully satisfying high heat flux cooling requirements.
Integrated structure for remarkable lightweight and cost reduction
Integrates heat dissipation and load-bearing functions, usable as a load-bearing tray for battery packs, achieving 10%–15% weight reduction. Aluminum alloy is over 40% lighter than copper cooling plates. The dual-circuit integrated design requires no extra volume, reducing parts and assembly costs to support vehicle lightweighting and range improvement.
Redundant design with automotive-grade lifelong reliability
Independent dual-circuit redundancy allows one circuit to serve as emergency backup if the other fails, ensuring uninterrupted thermal management. Vacuum brazing / FSW solid-state welding guarantees zero leakage (helium leak rate ≤1×10⁻⁹ mbar·L/s). It features salt spray resistance, corrosion resistance, wide temperature adaptability (-40℃ to 120℃), and service life ≥10 years. It has passed automotive-grade vibration (20g) and impact (50g) tests, suitable for complex road conditions.
Flexible customization for precise full-scenario adaptation
Dual-circuit flow channels (serpentine / parallel), port positions, and dimensions are customizable. Compatible with CTC / CTB integrated solutions and high-power commercial vehicle 3-in-1 thermal management systems, covering models from A00-class to heavy-duty commercial vehicles. Temperature control sensors can be integrated for independent dual-circuit temperature monitoring.
Controllable mass production with outstanding full-cycle cost performance
Mass production yield ≥98%, cost over 25% lower than two single-inlet single-outlet cooling plates and over 30% lower than microchannel cooling plates. Extends battery 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, improving space utilization and range stability to handle high heat flux cooling.
Commercial vehicles / heavy trucks: 3-in-1 thermal management for power batteries, motors, and electronic controls; independent dual-circuit temperature control adapts to high-load operation, complex road conditions, and high-power fast charging, ensuring redundant safety of the thermal management system.
Energy storage systems: Temperature control for battery packs in industrial and commercial energy storage containers; dual-circulation improves heat dissipation efficiency, adapts to high-power charging and discharging, and ensures safe and stable operation without local overheating.
Special vehicles: Battery cooling for construction machinery and logistics vehicles; dual-circuit redundant design enhances reliability under harsh conditions, adapting to high/low temperatures and strong vibration environments to extend component service life.
V. Selection and Installation Guidelines
Power matching: For 100–200 kWh battery packs, select 8–20 kW class dual-inlet dual-outlet liquid cooling plates; for 200 kWh and above, use 20–30 kW class units to meet high heat flux demands of vehicles with different ranges and power levels.
Flow channel selection: Dual parallel multi-branch channels are preferred for fast-charging models (low pressure drop, high flow compatible); dual serpentine channels for long-range models (high heat exchange, more uniform temperature control), supporting independent dual-circuit regulation.
Installation requirements: Ensure cooling plate flatness ≤0.05 mm, attach with thermal grease or phase change materials, and fasten bolts evenly to avoid deformation from local stress. Dual ports must correspond to vehicle thermal management pipelines with sealed connections.
Medium requirements: Use 50% ethylene glycol + 50% deionized water (conductivity <1 μS/cm). Regular replacement every 12 months is recommended to prevent scaling and clogging of dual circuits that reduce heat dissipation. Inspect dual-circulation patency regularly.
