Radiator plastic water tank production line
Stamping-Type Liquid Cold Plate Production Line
A stamped liquid cold plate (also known as stamped battery cooling plate or stamped brazed cold plate) is a high-performance thermal management component manufactured through precision metal stamping processes. It consists of a channel plate (lower plate) and base plate (upper plate) that are formed using stamping dies and then joined together through controlled atmosphere brazing (CAB) or vacuum brazing to create sealed internal cooling channels .
The manufacturing process involves stamping aluminum sheets (typically 3003 aluminum alloy with 4-series brazing layer) to form flow channel grooves with depths ranging from 2-5mm, followed by degreasing, flux coating, and high-temperature brazing at 500-700°C to create a leak-proof, lightweight heat exchanger .

People Also Ask
1. Q: What is automotive thermal management?
A: Automotive thermal management is the system of components and controls that regulate temperatures in vehicles, including battery thermal management systems (BTMS) for EVs, powertrain cooling for engines/motors, and HVAC systems for cabin comfort. Advanced systems integrate these loops using heat pumps and waste heat recovery to achieve up to 20% energy savings and extend electric vehicle range.
2. Q: How does battery thermal management system work?
A: A battery thermal management system (BTMS) maintains lithium-ion batteries at 25-40°C for optimal performance. Liquid cooling circulates coolant through cold plates for precise control (< 3°C variation). Air cooling uses forced convection for simpler, lighter systems. PCM (Phase Change Materials) absorb heat passively during solid-to-liquid transition. Advanced BTMS use AI control algorithms to predict thermal loads and optimize energy consumption.
3. Q: Why is thermal management important for electric vehicles?
A: Thermal management is critical for EVs because lithium-ion batteries degrade rapidly outside 25-40°C. Poor thermal control reduces charging speed by 50%+, cuts range by 15-30% in extreme weather, and risks thermal runaway. Effective systems enable 150kW+ fast charging, extend battery life to 1,000+ cycles, and preserve range via efficient heat pump heating (3x more efficient than resistive heaters).
4. Q: How do I choose between liquid cooling, air cooling, and PCM for my EV battery?
A: Liquid cooling is essential for high-performance EVs with fast charging (Tesla, BMW approach), offering precise temperature control (< 3°C variation) but higher cost and complexity. Air cooling suits economy EVs in mild climates with lower energy density batteries. PCM (Phase Change Materials) provides passive thermal buffering for premium applications, absorbing heat during phase transition without power consumption, but with slower response times.
5. Q: What are the latest trends in automotive thermal management?
A: Five key trends: (1) Integrated thermal management combining battery, cabin, and powertrain loops for 20% energy savings; (2) Heat pump replacing PTC heaters for 3x efficiency in heating; (3) Refrigerant direct cooling (two-phase) for ultra-fast charging support; (4) AI/neural network control predicting thermal loads and optimizing energy use; (5) Digital twins for real-time monitoring and predictive maintenance.
