Applications
The following fields commonly use Leipole Vortex Coolers:
Industrial automation – Cooling of PLC controllers and servo motors to avoid overheating and shutdown.
Machining – Literally cool down CNC tools and spindles in real-time so you can prolong tool life.
Electronic communications – Safeguard 5G base stations and server chips from functioning stably at high temperatures
Automotive manufacturing – For welding robots and battery pack temp management
Basic knowledge
Vortex cooling principle
The principle of Vortex Coolers is based on the vortex tube effect, when the compressed air enters the vortex chamber, it will be separated into hot and cold air streams through high-speed rotation, and the temperature of the cold air flow can also be reduced to lower than the ambient temperature.
How do you pick the right model?
1. Determine the Heat Load
- Measure the heat load inside the enclosure with BTU/hr or Watts.
- Consider heat generated by electrical components (e.g., transformers, PLCs, motor drives).
- Also consider for external heat, such as ambient temperature and solar radiation.
2. Identify the Required Cooling Capacity
- Use the formula:Cooling Required (BTU/hr) = Heat Load (Watts) × 3.41
- Compare this with the cooling capacity of vortex coolers available.
3. Consider the Enclosure Size and Material
- Larger enclosures require higher cooling capacity.
- Metal enclosures conduct heat differently than plastic ones.
- Ensure the vortex cooler fits within the available space.
4. Determine the Air Supply and Consumption
- Vortex coolers use compressed air (not electricity), so check:\ Available air pressure (typically 80-100 PSI required)\ Air consumption rate (measured in SCFM or L/min)
5. Consider Noise and Efficiency
- Vortex coolers can be noisy; so all the set will come with a muffler.
- For better solution, please also consider to purchase solenoid valve, air filter and thermostat.
6. Verify Installation Requirements
- Mounting options: Side, top, or door-mounted.
- Ensure proper airflow inside the enclosure for even cooling.
Frequently asked questions
Q1: What is the compressed air flow rate required for Vortex Coolers?
A: The air consumption of standard models is 5~20 SCFM (standard cubic feet per minute), depending on the cooling power.
Q2: Can it be used to cool high-temperature metal surfaces?
A: It can be used with high-temperature resistant air ducts (up to 300°C) to spray cold air directly at the heat source.
Q3: What is different between Vortex Cooling vs. Traditional Cooling
A:
| Features | Vortex Coolers | Air Conditioner |
| Refrigerant | NO need | Requires Freon or other refrigerants |
| Moving Parts | NONE | Compressor, fan, etc. |
| Maintenance Cost | Very low | Regular maintenance |
| Applicable Scenarios | Local cooling, small space | Large space overall cooling |

Selecting LEIPOLE vortex coolers
Check the heat load and the compressed-air supply before choosing a model.
How does a vortex cooler work?
Compressed air enters a vortex chamber and spins at high speed, which separates it into a hot and a cold stream. The cold stream, as low as -40 °C, is blown into the enclosure and the hot air is exhausted, so there is no refrigerant and there are no moving parts.
Read how vortex coolers workDoes a vortex cooler need electricity?
No. A vortex cooler runs on compressed air, typically at 80–100 PSI, and standard models use about 5–20 SCFM depending on cooling power. A solenoid valve and a thermostat can be added so air flows only when cooling is needed.
See cooling thermostatsHow do I size a vortex cooler for an enclosure?
Work out the heat load in watts, convert it with cooling required (BTU/h) = heat load (W) × 3.41, and compare the result with the LCL 106 to LCL 150 models. Then check that the compressed-air supply delivers the pressure and flow the model needs.
Confirm the modelWhen should I choose a vortex cooler instead of an enclosure air conditioner?
Vortex coolers suit local cooling of small enclosures or hot spots where compressed air is available and space is tight. For overall cooling of larger cabinets, compare enclosure air conditioners.
