Automotive Cavity-Type Liquid Cooling Plate

I. Product Overview

II. Core Selling Points (Concise Version)

• Efficient temperature control, free of thermal runaway

   

  Integrated cavity with dense flow channels improves heat exchange efficiency by 20%–40% compared with traditional cooling plates. Battery pack temperature difference ≤3℃, suitable for 4C–6C ultra-fast charging, avoiding high-temperature power limitation.
   
• Integrated structure, lightweight and cost-effective

   

  Dual functions of heat dissipation and load bearing; can be used as a load-bearing tray for battery packs, reducing weight by 10%–15%. Aluminum alloy is over 40% lighter than copper cooling plates, cutting down parts and assembly costs.
   
• Automotive-grade quality, lifelong reliability

   

  Vacuum brazing / FSW solid-state welding ensures zero leakage. Salt spray resistant and corrosion resistant, adaptable to a wide temperature range (-40℃ to 120℃), service life ≥10 years. Passed automotive-grade vibration and impact tests.
   
• Flexible customization, full-scenario adaptability

   

  Customizable flow channels (serpentine / parallel) and dimensions, compatible with CTC / CTB integrated solutions. Covers models from A00-class to heavy-duty commercial vehicles, with optional integrated temperature control sensors.
   
• Controllable mass production, cost-efficient full life cycle

   

  Mass production yield ≥98%, cost over 30% lower than microchannel cooling plates. Extends battery life by over 20% and reduces full life cycle TCO by over 15%.

IV. Typical Application Scenarios

• New energy passenger vehicles: Bottom cooling for battery packs of BEV / PHEV models, compatible with CTC / CTB integrated body design, improving space utilization and cruising range.
• Commercial vehicles / heavy trucks: Three-in-one thermal management for power batteries, motors and electronic controls, supporting high-power fast charging and adapting to complex road conditions and high-load operation.
• Energy storage systems: Temperature control for battery packs in industrial and commercial energy storage containers, supporting high-power charging and discharging, ensuring safe and stable operation.
• Special vehicles: Battery cooling for construction machinery and logistics vehicles, adapting to harsh working conditions and improving component reliability and service life.

V. Selection and Installation Guidelines

1. Power matching: 100 kWh battery packs use 10–15 kW cavity cooling plates; 200 kWh and above use 15–20 kW units, matching different cruising range models.
2. Flow channel selection: Parallel multi-branch flow channels preferred for fast-charging models (low pressure drop, high flow compatible); serpentine flow channels for long-range models (high heat exchange, more uniform temperature control).
3. Installation requirements: Ensure cooling plate flatness ≤0.05 mm. Attach with thermal grease or phase change materials, fasten bolts evenly to avoid deformation caused by local stress.
4. Medium requirements: Use 50% ethylene glycol + 50% deionized water (conductivity <1 μS/cm). Regular replacement every 12 months is recommended to prevent scaling from impairing heat dissipation.
