AI Server Liquid Cooling: Auto Filling & Recovery
AI and high-performance computing bring new liquid-cooling maintenance requirements. Based on the video description from FLYING KING RECYCLING ENGINEERING CO. , LTD. (鴻太工程), this article outlines KOOLTEC equipment functions and the information needed to assess a filling and refrigerant recovery project.
Preparing, filling and recovering the cooling circuit
The equipment described in the video combines metered filling, vacuum preparation, recovery and circuit flushing for semiconductor testing, precision laboratories and large server systems.
- Metered filling helps control the amount of coolant charged into the circuit.
- Vacuum preparation and moisture removal address residual gas and moisture before filling.
- Liquid and vapor recovery collect refrigerant during maintenance to reduce material losses.
- Circulation, filtration and flushing address small particles and oxides in the piping.
Assessing R-515B, R-1234ze and R-1233zd applications
The video lists these three refrigerants. Equipment selection requires confirmation of the actual fluid specification, circuit design, operating pressure and material compatibility. Cold-plate and immersion systems must each be assessed against their fluid and circuit requirements.
Information to prepare for a project review
Provide the refrigerant, system capacity, target charge, vacuum requirements and connection interfaces, together with the intended production, laboratory or maintenance application. These details inform configuration and acceptance criteria.
The video description states recovery above 90%. Actual performance depends on the refrigerant, system configuration and test conditions.
