2. Technology Deep Dive: The Embedded Tube Cold Plate Advantage
Within Winshare Thermal's diverse portfolio—which includes Brazed Cold Plates, FSW Cold Plates, Die Cast Cold Plates, and Deep Hole Drilled Cold Plates—the Embedded Tube Cold Plate holds a unique position for balancing supreme performance, durability, and cost-effectiveness.
2.1 Design & Construction
The core innovation lies in its construction: one or more metal tubes (typically copper or stainless steel) are precision-embedded and bonded into channels machined into a solid baseplate (often aluminum). This creates a direct, high-integrity thermal path from the heat-generating surface (e.g., IGBT baseplate or battery cell) to the circulating coolant.

Key Technical Benefits:
- Superior Reliability & Leak Resistance: The tube acts as a primary, pressure-resistant barrier. The bonding process creates a secondary seal, making it exceptionally robust against thermal cycling and vibration—a critical requirement for Energy Storage systems and industrial motor drives.
- Excellent Thermal Performance: Direct metal-to-metal contact and efficient fluid dynamics ensure low thermal resistance, effectively managing heat fluxes typical of modern IGBT modules.
- Material Flexibility & Corrosion Resistance: The use of stainless steel tubes with an aluminum baseplate combats galvanic corrosion, a common challenge in Water Cooling systems. This extends system lifespan and reduces maintenance.
- Design Flexibility：Tube paths can be customized to match specific heat source layouts, optimizing cooling uniformity across large surfaces like battery packs.
Comparative Advantage vs. Other Technologies:
- Vs. Brazed Cold Plates: While brazed plates offer the highest performance for ultra-high heat flux (e.g., AI Cooling), Embedded Tube designs provide a more cost-effective solution for high-power but less extreme applications, with superior tolerance for fluid contamination.
- Vs. FSW Cold Plates: FSW is ideal for lightweight, leak-proof aerospace applications. Embedded Tube plates excel in stationary or heavy industrial settings where ultimate ruggedness and lower cost are paramount.
- Vs. Deep Hole Drilled: Deep drilling is perfect for complex, 3D internal channels. Embedded Tube simplifies manufacturing for linear or gently curved flow paths, offering faster lead times and lower cost for many IGBT and battery cooling layouts.
