【Exhibition Live】

Today (June 10/11), the 16th Shenzhen International Thermal Conductivity & Heat Dissipation Materials Exhibition opens at Shenzhen World Exhibition & Convention Center. We are at Booth 14G77, Hall 14, welcoming many data center and liquid cooling system integrators. Our full range of products – EPDM liquid cooling hoses, PTFE hoses, silicone hoses, and more – is making its debut together.

【Liquid Cooling Hose Selection Guide】

Hose material directly determines cooling efficiency, safety, and maintenance cost. The table below compares mainstream liquid cooling hose materials, helping you quickly decide based on power density, coolant type, and service life.

① Cold‑plate liquid cooling – cost‑effectiveness & easy installation

→ EPDM hose or silicone hose

Flexible and easy to route, ideal for tight rack spaces

Compatible with deionized water, ethylene/propylene glycol solutions

Silicone hose offers a wider temperature range, suitable for fluctuating ambient temperatures

② Immersion liquid cooling – chemical compatibility & low permeability

→ PTFE hose

Resistant to dielectric fluids (fluorinated liquids) – no swelling, no leachables

Near-zero permeability, maintaining long‑term coolant purity

Transparent/semi‑transparent option for easy fluid inspection

③ High‑power AI servers – high pressure & long life

→ Stainless steel corrugated metal hose

Extremely high pressure rating (burst pressure ≥25 MPa), zero permeability

Service life >10 years, ideal for mission‑critical systems that cannot be shut down

Note: risk of galvanic corrosion when connected to aluminum cold plates – use insulating pads or electrochemically compatible design

④ Air conditioning / thermal management systems – excellent airtightness

→ CIIR butyl rubber hose

Better airtightness than EPDM or silicone, suitable for refrigerants or gas media

Good oil resistance, can be used for compressor oil return lines

⑤ High‑flow & suction/discharge dual‑duty (e.g., between CDU and reservoir, pump suction side, drain & maintenance)

→ EPDM suction & discharge liquid cooling hose (large diameter, Ø19–102 mm)

Strong negative pressure resistance: built‑in spiral steel wire prevents collapse under suction, ideal for pump inlet (vacuum side)

Large diameter: up to 102 mm (approx. 4 inches), meets high‑flow demands of multiple liquid‑cooled racks

Dual‑duty: works for both pressure delivery and suction/vacuum – one hose, two functions

Typical applications: main lines between CDU (Coolant Distribution Unit) and dry coolers/cooling towers, intake lines from reservoir to pump, temporary hoses for system drain & coolant recovery, header pipes for parallel racks
