these six manufacturers are top-tier choices.
III. Customization
What to look for in customization.
Customization involves six key aspects: Battery specifications (Trumonytechs customizes liquid cold plates based on your battery specs and thermal boundary conditions; each plate undergoes individual helium leak testing); CFD review (Cold plate configuration aligns with cell format; channel geometry accounts for peak heat load and allowable pressure drop; designs are validated via CFD before tooling, and volume production begins after sample approval); Flow channel topology (Design and simulation of liquid cooling plates; fluid simulation to analyze pressure drop and thermal distribution); Requirement-based customization (In-depth design and production tailored to specific needs—cell type, layout, space constraints, target temperatures, budget, etc.); Non-standard customization (One-stop service for energy storage and EV battery cold plates—from R&D to custom manufacturing; factory-direct pricing for both prototypes and mass orders); OEM (Direct manufacturer supporting OEM and non-standard customization). Comprehensive customization covers these six areas.
IV.
Manufacturing Process
What to look for in the manufacturing process.
Process overview: Stamped Brazing (Key steps: stamping/forming, degreasing spray, brazing, helium leak testing, powder coating or film application; materials: typically Al3003-mod for both flow channel plates and flat plates; insulation: powder coating or film); Vacuum Brazing (Process: CNC milling internal channels/micro-fins into top/bottom base plates, placing brazing filler material—e.g., Al-Si foil—between layers, heating in a vacuum to melt the filler while keeping the base material solid so the liquid filler fills gaps via capillary action, cooling to form a fully metallurgical sealed weld; core advantage: oxygen exclusion, no flux required); CAB / Controlled Atmosphere Brazing (Stamped cold plates reinforced with internal fins for thermal efficiency; materials: typically 3003 aluminum with a 4000-series aluminum cladding layer acting as filler; water-based flux applied during welding; 100% leak testing); Machining (Machined cold plates: channels created via machining processes); High-Temperature Brazing (Capabilities: continuous high-temp brazing, vacuum brazing, and friction stir welding; reliable, high-quality welding services); Friction Stir Welding (Capabilities: continuous high-temp brazing, vacuum brazing, and friction stir welding). Summary of the six processes: Stamped Brazing, Vacuum Brazing, CAB, Machining, High-Temperature Brazing, and Friction Stir Welding.
V. Model Selection
What to look for in model selection?
Based on practical experience, the approach is as follows: Temperature difference—(Energy storage PACK liquid cooling plates; Donghao Zhichuang workshop footage; uniform heat exchange in flow channels; temperature difference strictly controlled within 3°C; fully in-house processing; compatible with various containerized energy storage systems and large-capacity cells; driving thermal management upgrades; precise temperature control extends power station lifespan by 30%); Flow channel structure—(Military-grade ATR chassis liquid cooling plate channel selection and testing; heat dissipation ranking: fin-type > cylindrical-type > embedded copper tube-type; fin-type offers peak performance for high heat density but comes at a high cost; cylindrical-type offers balanced, stable, and reliable performance; embedded copper tube-type is a low-cost solution but requires attention to leakage risks; thermal design fundamentals: heat exchange and fluid flow); U-shaped flow channel—(Energy storage system engineering; liquid cooling for prefabricated containerized energy storage systems; coolant circuit design; a U-shaped channel at the very bottom where the battery sits; channel width determined by battery heat generation requirements—calculating the heat dissipation power of a single battery); Materials—(Materials for stamped liquid cooling plates in energy storage 30
03 Cold Plate Brazing: Understanding Channel Plate Materials. The upper plate—also known as the cover plate or top cover—is a thin, 1.5mm aluminum sheet made of 3003 alloy. The lower plate—referred to variously as the bottom plate, channel plate, or base plate—uses 3003-MOD material; this is a modified composite or alloy. Leak testing covers airtightness, pressure resistance, burst pressure, internal channel cleanliness, thermal cycling, joint tensile strength, microstructure, and flatness; the quality of the brazing directly determines these critical product performance metrics. Load-bearing capacity: Yixinneng’s new-generation reinforced liquid cooling plate (designed for energy storage export projects) is engineered to support a load of 600 kg. Yixinneng focuses on liquid cooling for energy storage, backed by 25 patented technologies. Six key factors for selection: temperature difference, channel structure, U-shaped channels, material, leak testing, and load-bearing capacity.
Evaluating these six factors ensures the right choice.
