JLCT Cooling Towers: Decoding the ＂Heat Dissipation Code＂ for Semiconductor ManufacturingIn semiconductor manufacturing, a field with extremely stringent requirements for the production environment, temperature fluctuations and humidity out of control can scrap an entire batch of wafers. Core process equipment such as lithography, etching, and coating generates large amounts of heat during operation. If this heat cannot be dissipated in time, it may at least affect chip yield, and at worst cause equipment damage and production line interruption. Therefore, circulating water cooling systems have become one of the indispensable key supporting facilities in wafer fabs.
As an international brand under Zhejiang Jinling Refrigeration Engineering Co., Ltd., JLCT relies on years of accumulated cooling technology and continues to deepen its presence in semiconductor and electronics manufacturing. Recently, with its JNT series crossflow open-circuit cooling towers as the core, JLCT has provided professional cooling solutions for multiple high-end electronics manufacturers, safeguarding large-scale semiconductor production.
1. Capacity Expansion, Upgraded Cooling Demand
The global semiconductor industry continues to expand production, and chip manufacturing has increasingly stringent requirements for environmental stability. Precision equipment in cleanrooms requires an uninterrupted circulating cooling water supply throughout the year. The extreme constant temperature in lithography areas and the high-load heat dissipation of etching equipment pose severe challenges to the reliability and energy efficiency of cooling systems.
In response to the high-standard needs of the semiconductor industry, JLCT has customized circulating cooling water system solutions centered on the JNT series.
2. JNT Series: The "Heart" of the Cooling System
The JNT series crossflow open-circuit cooling tower integrates high-efficiency heat exchange, low-noise operation, energy saving, and water saving. It has passed CTI, CCTI, and China energy-saving and water-saving certifications. A single unit covers a circulating water volume of 85 m³/h to 1,500 m³/h, flexibly adapting to different project needs. Structurally, it adopts a crossflow layout, with air and water flows crossing perpendicularly, achieving high heat exchange efficiency and low air resistance. The steel frame, combined with high-efficiency fill and low-drift eliminators, is corrosion-resistant and long-lasting, capable of handling the harsh conditions of long-term continuous operation in semiconductor plants.
3. Three Key Pain Points, Addressed One by One
The core requirements of semiconductor manufacturing for cooling systems can be summarized in three keywords—stability, precision, and efficiency.
Stability: The JNT series has a steel frame with strong rigidity and fewer connections, ensuring high stability. The motor has IP55 protection and Class F insulation, offering high-temperature resistance and pressure fluctuation resistance, with strong adaptability to pressure changes. This fully ensures the cooling tower's service life and operating performance under year-round uninterrupted operation in semiconductor plants.
Precision: The large-aperture gravity water distribution tray distributes water evenly and is not easily clogged; nozzles are easy to remove and clean. Combined with high-efficiency axial fans with adjustable blade angles, it can match rated horsepower to the greatest extent and achieve optimal operating conditions, enabling precise water temperature control and meeting the semiconductor process's stringent requirements for extremely small temperature fluctuations.
Efficiency: The product has passed national energy-saving and water-saving certification. The fill uses JLCT's self-developed invention patent SX-COMB high-efficiency fill, with Class B1 combustion performance and temperature resistance above 65°C, and a service life of more than 15 years. The fan uses high-efficiency airfoil aluminum alloy blades and a galvanized hub, operating at low speed with low noise and vibration. Ultra-low-noise fans are optional for sensitive areas, balancing energy saving and environmental protection.
From cooling tower renovations for high-end chip factories to circulating water system support for newly built wafer fabs, JLCT continues to appear at key nodes in the upgrading of China's semiconductor industry.
Semiconductors are the core cornerstone of strategic emerging industries, and their production processes cannot do without the safeguard of stable and reliable cooling systems. JLCT cooling towers deeply understand industry needs and provide efficient, reliable, and green cooling solutions for the industry.
