Exclusive Liquid Cooling Solution for High Heat Flux in New Energy Vehicles
Dual-circulation design enables efficient temperature control and safe range extension for high-performance automotive applications.
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 features innovative 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.
This product combines 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.
Core Advantages
Dual-circulation for efficient temperature control: Independent dual-inlet dual-outlet loops provide split-flow heat dissipation and synchronous temperature control. Heat exchange efficiency is 30%-50% higher than traditional single-inlet single-outlet cooling plates.
Integrated structure for lightweight design: Combines heat dissipation and load-bearing functions, achieving 10%-15% weight reduction. Aluminum alloy is over 40% lighter than copper cooling plates.
Redundant design with automotive-grade reliability: Independent dual-circuit redundancy ensures uninterrupted thermal management. Vacuum brazing/FSW solid-state welding guarantees zero leakage with helium leak rate ≤1×10⁻⁹ mbar*L/s.
Flexible customization for precise adaptation: Dual-circuit flow channels, port positions, and dimensions are customizable. Compatible with CTC/CTB integrated solutions and high-power commercial vehicle thermal management systems.
Controllable mass production with excellent cost performance: Mass production yield ≥98%, cost over 25% lower than two single-inlet single-outlet cooling plates. Extends battery life by over 20%.
