Product Description
Product Overview

Our Liquid Cooling Plates (LCPs) are precision-engineered thermal management components designed for electric vehicle battery packs and stationary energy storage systems. We offer two proven technologies: Stamped Brazed plates with intricate flow networks for superior heat distribution, and Serpentine Tube designs optimized for cylindrical cell geometries. Both configurations deliver exceptional cooling efficiency, structural durability, and leak-tight integrity. With full customization capabilities and rapid CFD simulation support, we provide North American OEMs and Tier 1 suppliers with reliable, production-ready thermal solutions that enhance battery safety, extend cycle life, and maximize driving range in all climates.

Key Features at a Glance
  • Stamped Channels: Complex flow paths formed in seconds at low cost, ideal for high-volume scaling.
  • Leak-Proof Construction: Solid-state sealed for permanent, maintenance-free operation with no internal contaminants.
  • Custom Configurable: Size, port locations, mounting bosses, and surface treatments can be tailored to your module layout.
  • Fast Sample Turnaround: Functional prototypes delivered in weeks, using the same production-ready process.
  • Certification Support: Full documentation and material traceability to assist with UL 1973 and UL 9540A compliance.

Our Engineering Solutions (Solution)

✔ Stamped Brazed – Superior Thermal Uniformity: Utilizing high-grade aluminum alloys (3003/6063) with precision vacuum brazing, our stamped plates feature multi-pass flow networks that ensure coolant distribution is perfectly matched to cell heat maps. Achieve surface temperature differentials as low as ≤2°C across the entire pack, minimizing cell imbalance and maximizing usable capacity. The brazed construction provides excellent structural rigidity, making these plates ideal for load-bearing CTP applications.

✔ Serpentine Tube – Lightweight Cylindrical Cell Optimization: Purpose-built for cylindrical formats (18650, 2170, 4680), our serpentine tubes are manufactured using precision CNC bending and orbital welding. The sinusoidal routing maximizes surface contact with each cell row, while thermally conductive gap fillers bridge the line-contact interface, reducing thermal resistance by up to 40%. With pressure drops below 18kPa, these tubes minimize parasitic pump energy losses.

✔ Zero-Compromise Leakage Protection: Every plate undergoes 100% helium leak detection with sensitivity down to 1×10⁻⁷ Pa·m³/s – 10x tighter than typical industry requirements. Our proprietary surface passivation process, combined with coolant additive compatibility testing, ensures long-term resistance to pitting, crevice corrosion, and stress corrosion cracking, even with aggressive glycol formulations.

✔ Production-Ready Customization: From prototyping to high-volume production (capable of 500,000+ units annually), we support your entire product lifecycle. Our in-house tooling, stamping, brazing, welding, and assembly capabilities ensure complete process control and faster time-to-market.

FAQ
Q1: I don’t have a finalized design. Can you help from the concept stage?

Absolutely. That is the core of our one-stop service. Share your heat load, space envelope, and target thermal performance. Our engineers will propose an initial flow channel design, run CFD simulations for your approval, and then move to prototype. We guide you from idea to serial production.

Q2: What is the minimum order quantity (MOQ) for custom liquid cooling plates?

We have no fixed MOQ for the prototype and NPI (New Product Introduction) stage. For mass production, we work flexibly with your volumes. As a factory serving global clients, we comfortably handle everything from small pilot runs to millions of pieces annually.

Q3: How do you ensure zero leaks in a water-cooled battery pack?

Quality is built in from the start. We use vacuum brazing for high-integrity joints and 100% test every single plate with a helium mass spectrometer, achieving leak rates tighter than 1*10⁻⁹ Pa·m³/s. Additionally, we conduct pressure cycling and thermal shock tests on pre-production samples validated according to customer durability requirements.

Q4: Do you hold certifications for the North American and Asian markets?

Yes. Our manufacturing is certified to ISO 9001 and IATF 16949. Our materials and components comply with RoHS, REACH, and UL standards as required by your product. We are also experienced in supporting customers through final system-level UL 9540A or UN 38.3 certification by providing detailed design and material documentation.

Q5: What kind of warranty and after-sales support do you offer for your cooling plates?

We stand behind our workmanship. Our standard product warranty is 5 years when properly operated within specified parameters. In the rare event of an issue, our engineering team provides root cause analysis and works to resolve it immediately. For ongoing production, we maintain complete traceability records tied to each batch.
