CAPILLARY PUMPED LOOPS are break through cooling solutions.

Used in Power Converters applications, they absorb the heat from the high power modules and move it passively to a remote Heat Exchanger (air or liquid), where it can be easily removed.

• Thermal Advantages

• High heat loads: with power losses up to 4kW per pack and heat densities up to 100W/cm², each power module can be used at its extreme limits.

• Very low thermal resistance: usually below 0,005K/W depending on the application, junction temperatures can be significantly reduced.

• Isothermal & uniform cooling: vaporization creates a constant temperature (+3K maximum) all across the evaporator, keeping power modules chips.

• No derating: thanks to the isothermal cooling, power modules can be used more intensely.

• High temperature operating range: capable to operate in any ambient air conditions from -50°C to +50°C, CALYPOWER can be used in the most extreme environments.

• Mechanical Advantages

• Easy and Anti-gravity design: thanks to its capillary pump, designs against gravity or with remote heat exchangers can be realised, making new or retrofit designs even easier.

• Custom number ofmodules per evaporator: evaporators can be single or double-sided, with several modules per side.

• Interchangeability: thanks to the uniform cooling, power modules from different manufacturers can be used without changing the cooling solution.

• Safety & Reliability Advantages

• Cooling: no maintenance no failure. CPL don’t have any mechanical moving part or power consumption. Life time up to 40 years can be guaranteed.

• Power modules: higher reliability. With lower junction and swing temperatures, power modules life time can be significantly increased.
