Other features of "SIPHOREX"
High Reliability
Form our experience of 25 years, SIPHOREX has experienced no failure, besides external reason (e.g. corrosive environment, external force)
Uniform cooling surface temperature
Since temperature of contained liquid inside becomes uniform with saturation temperature, cooling surface also becomes almost uniform.
Sub-zero ambient temperature OK.
Since freezing point of refrigerant is very low, SIPHOREX does work in sub-zero ambient. (more than -40degC possible)

Suggestions for high-performance CPU cooler
Hope to increase the processing capacity and speed of equipment. (increasing CPU heat value)
Hope to reduce the power consumption of air conditioning. (raising the room temperature setting value)
However, you do not want to use the water cooling method. (leakage, maintenance, power consumption).
I wish a high-performance air-cooled cooler...
Data center
The performance of the cooler is low,
Acceptable CPU temp.: 70 Temperature rise value T: 45C Need to keep the room temperature low
Outdoor unit
Air conditioner
Room temperature 25
Server rack
CPU cooler
The performance of the cooler is good,
Acceptable CPU temp.: 70 Temperature rise value T: 30C The room temperature can be kept high!!

Suggestions for high-performance CPU cooler
Cooling method comparison
Heat sink Low cost Low cooling performance
Liquid cooling High cooling performance Need pipng, Maintenance
Liquid immersion Cooling performance High Large space, High cost
Air cooling with phase change Siphorex for CPU/GPU
Cooling performance similar to liquid cooling Smaller space than liquid cooling / immersion Higher cost than heatsink
Possible for 1000W
