Cooling Tower
This cooling tower is a device that dissipates heat generated during industrial production into the atmosphere through the principle of evaporative cooling, thereby reducing system temperatures and ensuring equipment operates within ideal thermal conditions. The cooling tower typically comprises a tower body, fill, fan, water pump, and other components. The design of the fill maximizes the contact area between water and air, enhancing cooling efficiency. Based on application requirements, cooling towers can be categorized into wet, dry, and hybrid types, catering to production lines of varying scales and process demands.

Product Introduction
Technical Background
As of May 2025, in high-speed continuous plastic extrusion production, cooling tower-integrated cutting machines must address the conflict between high residual thermal stress release and precision wet-environment cutting. With engineering plastics (e.g., LCP, PPS) now processed at temperatures exceeding 380°C, traditional cutting machines face challenges such as material rebound (error >0.2mm) and tool thermal expansion (linear deformation >50μm/m) due to uneven cooling. These issues are critical for products requiring strict dimensional tolerances (±0.05mm), such as 5G high-frequency substrates and aerospace composite tubes. Industry innovations focus on three key areas:
Thermal-Mechanical Coupling Control:
A Fiber Bragg Grating (FBG)-based distributed temperature sensing network coordinates a liquid nitrogen atomized spray system to achieve gradient temperature control (gradient difference <5°C/cm) in the cutting zone, minimizing phase-change deformation.Dynamic Compensation Cutting:
A magnetic levitation linear drive blade set (acceleration: 15m/s²) integrates an AI deformation prediction model. Real-time compensation algorithms correct extrusion swell effects (e.g., 1.5% expansion in PP materials) within 300ms.Eco-Synergistic Design:
Silicon carbide whisker-reinforced ceramic blades (temperature resistance >1200°C) combined with pure water-based cooling lubrication reduce volatile organic compound (VOC) emissions to near-zero levels, complying with EU CRPⅡ regulations. Recent cases show this technology achieves 89.9° verticality in carbon fiber-reinforced PEEK tube cuts, meeting AS9100 aerospace standards.
Structural Composition
- Thermal Management Unit: Dual-layer honeycomb aluminum with integrated microchannel liquid cooling plates (heat exchange efficiency >500W/m²K).
- Drive System: Three-axis magnetic levitation linear modules (repeat positioning accuracy ±2μm) supporting 0–1200 cuts/min frequency conversion.
- Cutting Assembly: Polycrystalline CBN-coated disc blades (edge radius ≤0.01mm) with self-cleaning air-film isolation layers.
- Detection Module: Terahertz wave online thickness gauge (0.1μm resolution) and infrared thermal imager (temperature sensitivity 0.1°C).
- Intelligent Core: An edge computing unit synchronizes cooling tower fans via OPC UA protocol, enabling temperature-tension-cutting sequence triple closed-loop control.
