Liquid Cooling

Vloeistofkoelers

Telerex also supplies liquid coolers for OEM solutions or thermoelectric assemblies. Standard capacity varies from 500 to 5000 watts, suitable for medical imaging, laser equipment, laboratory testing equipment, agricultural machinery and similar. In the liquid cooler, the cooling fluid is circulated by means of a pump with a high MTBF. The heat of the coolant is absorbed by a heat exchanger and subsequently driven off through heat sinks with high density. The modules are custom designed for long life and can be easily operated by means of a digital temperature controller. Customizations and configurations are possible.

Variations of liquid cooling

  • Oil or water cooling
  • Liquid to air
  • Air to liquid
  • Recirculation

Advantages of LiquidCooling Systems

LCS are unique to the thermal management market in that theyuse a coolant to transfer heat. Most engineers are concerned aboutintroducing liquids to their electronics, but if the unit is designedand assembled correctly, it becomes a non-issue. LCS have severaladvantages over conventional air-cooled systems.

  • High Heat Pumping Capacity
    Liquid heat exchangers can reducethe thermal resistance of conventional heat sink fan dissipationmechanisms by a factor of 10 or more. This is due to the poor thermalproperties of air versus coolants such as water.
  • High Heat Flux Density
    LCS can remove up to five times theamount of heat per square area over conventional air cooling systems.This becomes advantageous in densely packed electronics with limitedspace to accommodate an air cooling mechanism.
  • Heat Routing
    Liquid cooling allows the integration of a small heatexchanger to be located at the heat source, which then routes heataway through a liquid circuit. This is advantageous in densely packedelectronics where a conventional air cooling system pushes air allaround system and potentially adds heat to the system from other hotelectronics in close proximity.
  • Rapid Cool Down
    Cool down time is a function of cooling capacity.LCS have larger cooling capacities than conventional heat sink fanmechanisms, which will reduce the time it takes to reach temperature.
  • Lower Noise
    Systems with high heat removal requirements of onekilowatt or higher require much larger fans to generate the air flowneeded to dissipate heat. This makes the air cooling system noisier,exposes system to higher vibration and potentially requires a largersystem than that of an LCS.
