Key Differences Between Water-Cooled and Air-Cooled Thermal Shock Test Chambers

November 22, 2025

Comparison Dimension	Water-Cooled	Air-Cooled
Cooling Principle	Relies on deionized/distilled water circulation, dissipates heat via water-cooled condenser	Fans drive ambient air to complete heat exchange through air-cooled condenser
Installation Requirements	Requires supporting water system (water tank/pipeline/water pump), grounding ≤4Ω, drainage height difference ≥10cm	No water pipeline needed; leave ≥30cm space around the machine, ambient temperature 5-35℃, humidity ≤85%
Core Performance	High heat dissipation efficiency, stable temperature control, not affected by ambient temperature, suitable for continuous operation	Medium efficiency, prone to performance degradation in high-temperature environments, more suitable for intermittent tests
Cost & Maintenance	High initial investment; needs monthly water change and tank cleaning, regular inspection of pipeline seals and rust prevention	Low initial investment; only needs air filter cleaning 1-2 times a month and fan inspection
Applicable Scenarios	Industrial laboratories, high-power equipment (volume >100L), continuous operation in high-temperature environments	Small and medium-sized laboratories, scenarios without water supply, medium-low power (volume <100L) intermittent tests
Key Prohibitions	Prohibit unqualified water; prohibit blocking filters/drainage ports	Prohibit frequent start-stop (wait ≥5 minutes after shutdown before restart); prohibit placing flammable and explosive materials

Core Selection Recommendations

1. Choose water-cooled: For industrial scenarios with high power, continuous operation, high-temperature environment or extremely high requirements for temperature control accuracy (stable water supply required).

2. Choose air-cooled: For general laboratories with limited space, intermittent use and no water supply, pursuing low cost and convenience.
