Safety test

Test Background

The liquid-cooling system operates under pressure (0.3-1.0 MPa). Once the coolant leaks, it may cause safety accidents such as electrical short-circuits, equipment damage, and even fires. The safety test is the red line for ensuring personnel safety and stable operation of equipment.

Test Introduction

The safety test covers explosion-proof and flame-retardant tests, leakage detection, electrical safety regulations, and emergency heat-dissipation tests. It comprehensively evaluates the system's safety protection ability under abnormal operating conditions to ensure that no safety accidents occur under any failure mode.

FAQ
Q: What is the concept of a leakage rate of 1×10⁻⁶ Pa·m³/s? A: It is equivalent to a gas volume of about 0.001 ml leaking per second under 1 atmosphere, which is one-ten-thousandth of a drop of water and belongs to an ultra-high sealing level.
