Hose Selection Guide for Temperature Control Water Systems in Data Center, Semiconductor, Laser and Medical Equipment

<p>Data center, semiconductor, laser and medical equipment belong to different industries, but their temperature control water circuits are highly similar: all get cold source from Chiller, get precise temperature adjustment from TCU, and absorb heat from heating points via Cold Plate, with hoses connecting these three parts into a closed loop. The difference lies in working conditions: some require ultra-high cleanliness, some need pulse resistance, and others demand flame retardancy. This article breaks down hose selection by application scenario, with a practical selection checklist and frequently asked questions.</p> <p style="text-align:center;margin:18px 0;"><img src="/data/upload/20260917/wc_hose_3_cover.jpg" alt="Liquid cooling system with Chiller-TCU-Cold Plate collaboration: data center / semiconductor / laser / medical" style="max-width:100%;height:auto;border-radius:4px;" /></p> <h2>Scenario 1: Data Center Liquid Cooling</h2> <p>Data centers use cold plates to transfer server heat to CDU (Cooling Distribution Unit), which is then cyclically cooled by Chiller. Branch hoses emphasize **low leaching, flame retardancy, and no contamination to servers**, with relatively stable pressure and temperature (15~35℃).</p> <p>**Selection Key Points**: Low leaching silica gel or PVC inner liner, flame retardant outer layer; fewer connectors reduce leakage points and facilitate routing inside the cabinet.</p> <h2>Scenario 2: Temperature Control for Semiconductor Equipment</h2> <p>Semiconductor process chambers are extremely sensitive to temperature. TCU stabilizes water temperature within ±0.1℃ or even a narrower range, and the flow channel of the cold plate is a micro-channel, so cleanliness is the top priority.</p> <p>**Selection Key Points**: PTFE / FEP low leaching inner liner, eliminates particle and plasticizer contamination; high-purity interfaces, cleanable.</p> <h2>Scenario 3: Laser Equipment Cooling</h2> <p>The laser head generates concentrated heat, and the hose between Chiller and the laser head cold plate often withstands medium-pressure pulses and short-term local high temperature, so the hose must be **pressure resistant, pulse resistant, and temperature resistant**.</p> <p>**Selection Key Points**: Silicone braided reinforced hose, burst pressure ≥ 3~4 times working pressure; confirm the maximum continuous operating temperature for short sections near heat sources.</p> <h2>Scenario 4: Medical Instruments</h2> <p>Medical instruments require biocompatible materials, cleanability and long-term stability, and their temperature control water circuits are mostly stable low pressure with a wide temperature range (4~40℃).</p> <p>**Selection Key Points**: Medical grade silicone inner liner, low leaching, cleaning resistant; reliable connectors, no dead corners for fluid accumulation.</p> <h2>How to Select for Four Scenarios: A Complete Selection Table</h2> <table border="1" cellpadding="6" cellspacing="0" style="border-collapse:collapse;width:100%;margin:12px 0;"> <tr><th>Scenario</th><th>Cold Source</th><th>Typical Temperature</th><th>Pressure Characteristics</th><th>Recommended Inner Liner</th><th>Key Requirements</th></tr> <tr><td>Data Center Liquid Cooling</td><td>Chiller + CDU</td><td>15~35℃</td><td>Stable low pressure</td><td>Silicone / PVC</td><td>Low leaching, flame retardant</td></tr> <tr><td>Semiconductor Temperature Control</td><td>Chiller + TCU</td><td>5~40℃</td><td>Precision low pressure</td><td>PTFE / FEP</td><td>Ultra-high cleanliness, no leaching</td></tr> <tr><td>Laser Cooling</td><td>Chiller + TCU</td><td>10~30℃</td><td>Medium pressure pulse</td><td>Braided silicone</td><td>Pressure resistance, pulse resistance</td></tr> <tr><td>Medical Instrument</td><td>Chiller / Small TCU</td><td>4~40℃</td><td>Stable low pressure</td><td>Medical grade silicone</td><td>Biocompatible, cleanable</td></tr> </table> <h2>KUNGFLEX Corresponding Solutions for Four Scenarios</h2> <p>KUNGFLEX (Shanghai Beirun Hydraulics Equipment Co., Ltd.) provides customizable temperature control waterway hoses and connectors for the four scenarios mentioned above:</p> <ul><li>**Data Center**: Low leaching flame retardant silicone hoses, equipped with quick plug connectors, reduce the risk of server contamination.</li><li>**Semiconductor**: PTFE / FEP low leaching high-purity hoses, matching the connection from TCU to process chamber cold plate.</li><li>**Laser**: Silicone braided pulse-resistant hoses, covering the connection from Chiller to laser head cold plate.</li><li>**Medical**: Medical grade silicone cleanable hoses, with long-term stability and material compliance.</li></ul> <h2>Practical Selection Checklist (Check as You Go)</h2> <p>1. What is your cold source: Chiller / TCU / Chiller + TCU combination?</p> <p>2. Is the flow channel of the cold plate at the heating point a micro-channel or a conventional channel? What is the cleanliness requirement?</p> <p>3. What type of coolant is used: deionized water, ethylene glycol aqueous solution, antifreeze or others?</p> <p>4. What is the working temperature range (including whether the minimum temperature is lower than 0℃, and whether there is short-term high temperature)?</p> <p>5. Pressure and pulse: What is the working pressure? Will pump / valve start and stop cause pulses?</p> <p>6. Any special requirements such as flame retardancy / biocompatibility / food grade?</p> <p>7. Connector type: quick plug, thread or flange? Can leakage points be further reduced?</p> <h2>Frequently Asked Questions</h2> <p>**Q: Can data centers and semiconductors use the same hose?**</p> <p>A: Generally not recommended. The top priorities for data centers are low leaching + flame retardancy, while for semiconductors they are ultra-high cleanliness + no leaching. The requirements for inner liner and certification are different, so separate selection is required.</p> <p>**Q: Why is the section from TCU to Cold Plate particularly prone to problems?**</p> <p>A: This section has the strictest temperature accuracy requirement, is closest to the heating point, and often withstands pulses caused by TCU valve actions. It is the most demanding section of the entire loop, so the pulse resistance and temperature resistance of the hose need to be checked emphatically.</p> <p>**Q: Does the hose need to be flame retardant?**</p> <p>A: It is recommended to choose flame retardant outer layer for occasions with fire protection requirements such as data centers and computer rooms; for semiconductors and medical applications, it depends on the process environment, but flame retardancy is usually a plus.</p> <p>**Q: Can you customize according to our interface and pressure requirements?**</p> <p>A: Yes. KUNGFLEX supports customizing hose assemblies and connectors according to the interface form, temperature range and working pressure of Chiller, TCU and Cold Plate.</p> <h2>About Shanghai Beirun Hydraulics Equipment Co., Ltd.</h2> <p>Shanghai Beirun Hydraulics Equipment Co., Ltd.
