ALAZ ARIMA, S.L.

ALAZ ARIMA S.L. is a Navarrese company founded in June 2016. It was set up with the aim of offering cooling systems based on phase change technology for the renewable energy and mobility sector.

ALAZ ARIMA’s solutions use the phase change of fluids to transfer heat through elements called thermosyphons. A thermosyphon is a device that allows the transfer of heat from one place to another, with a thermal conductance equivalent to better than that of any other known element. They are often referred to as ‘heat superconductors’, as they have a high capacity and rate of heat transfer with almost no losses. They are simple devices, with no moving parts and highly efficient, which make it possible to dispense with certain components, simplifying the cooling system and thus managing to offer optimised solutions, without electrical consumption and without maintenance; passive cooling solutions.

ALAZ ARIMA has facilities equipped to validate its developments under the most unfavourable operating conditions. Tests are carried out to certify the performance of the developed solutions in the different operating conditions. Rapid prototyping and characterisation.

ALAZ ARIMA offers high performance passive cooling solutions for:

  • Power electronics.
  • Electrical machines.
  • Enclosures.

Mainly applicable to the renewable energy sector such as Photovoltaic Solar Energy and Wind Energy, as well as Electric Mobility, for:

  • Photovoltaic inverters, inductors and electrical cabinets.
  • Wind converters, nacelles, gearboxes and transformers.
  • Traction converters.

Refrigeration systems consist of an evaporator, in which the heat is collected, a dissipator where the heat is evacuated and flexible pipes that connect them together to allow the circulation of the fluid. This makes it possible to disconnect them by means of fittings or quick couplings, greatly facilitating assembly and maintenance work. In continuous innovation to meet the most demanding cooling needs, the fluids are selected and customised, being totally respectful of the environment and current regulations.

ALAZ ARIMA solutions allow to improve the performance of conventional systems, as they offer:

  • Higher power densities due to low thermal resistance.
  • Higher reliability. Fewer components, fewer failure modes.
  • Reduced power consumption. Passive pumping and high efficiency condenser with low pressure drop.
  • Increased service life. 25+ years per CANCSA-S500-14.
  • Extended operating temperature to minimise derating.
  • Adaptive thermal resistance prevents condensation at low temperatures. Thermal diode.
  • Low temperature dispersion on the component surface.
  • Weight reduction. Compactness.
