Our Shell and Tube Heat Exchanger is engineered to provide superior thermal performance for modern industrial HVAC and refrigeration systems. Specifically optimized for modular chillers and cold/hot water units, these exchangers leverage advanced manufacturing techniques to ensure long-term reliability and high heat transfer coefficients.
Patented Technology & Structural Excellence
The core advantage of our design lies in the Shenshi Spiral Baffle. Unlike traditional segmental baffles, our unique locking design ensures the splicing area is tightly stitched, creating a smooth and natural transition. This geometry results in a uniform water-side flow rate, which significantly reduces the risk of freezing while maximizing heat exchange efficiency.
Advanced Manufacturing Process
Every Shell and Tube Heat Exchanger we produce undergoes a rigorous fabrication process using state-of-the-art equipment:
- Laser Tube Cutting & Machining: We utilize four-axis machining centers for high-precision tube sheet and flange processing, ensuring perfect sealing surfaces.
- Robot Tube Expansion: Our automated robot expansion process guarantees consistency and eliminates the risk of long-term transport defects common with manual expansion.
- Laser Welding: We implement fluorine-side head laser welding with penetration depth exceeding 2.2mm, maintaining a localized temperature below 65°C to protect material integrity.
- Precision Inspection: Units are validated using 2D projection and specialized welding inspection equipment to ensure zero-leakage reliability.
Technical Specifications & Capacity
Our product line covers a wide spectrum of cooling and heating requirements. For evaporation conditions, our units support cooling capacities from 65kW to 400kW. Under heating conditions, the heat production can reach up to 440kW, making them ideal for large-scale industrial applications. The internal 7mm heat exchange tubes feature a bottom wall thickness of 0.35mm, optimized through multiple design rounds for peak thermal flux.
