A new intelligent cooling concept from Aavid Thermalloy

HydroSink™ from Aavid Thermalloy is an intelligent, innovative, high performance Liquid Cooling System which aims to replace existing air cooled systems. HydroSink™ is the most efficient and convenient solution for medium and high power electronics.

HydroSink™ drastically reduces costs compared to traditional air cooling systems. This is the result of the three main advantages that it provides: compactness, high-reliability and optimized thermal performance.

It is produced using the most reliable components on the market, while the liquid cold plate is fully

customizable.

HydroSink™ is available in two sizes: “Small” and “Medium”; it can be supplied ready installed in a cabinet or as separate components. The small cabinet measures 465x400x525 mm and the medium cabinet measures 610x400x680 mm (stand-alone system without LCPs mounted). The nominal dissipated powers are 3.0 kW and 9.9 kW respectively, while they can work in a wide range of thermal resistances by acting on fan and pump speed (“Small” size: 7.0÷21.0 °C/kW and “Medium” size: 2.9÷9.0 °C/kW). Both Small and Medium Hydrosink are CE certified.

When supplied as separate components the system can be arranged in different ways and positions,

according to customer’s needs, giving high installation flexibility. The liquid cold plate(s) can be located

inside a customer’s sealed cabinet, with remote location for pump and heat exchanger or close to them for a more compact solution.

The system is produced using the most reliable components on the market, while the liquid cold plate is fully customizable. The pump has ultra-hard wearing resistant ceramics ball support, self-realigning rotor with magnetic support; the fan used has been homologated for automotive applications and both have a life-span of more than 50,000 hours. The system has components working in AC that can be used both in US and Europe without any adaptor being needed.

The control system is simple and efficient, able to monitor the operating conditions and to modify them if and when needed. The controller allows the fan and the pump to slow down when ambient temperature or power dissipated permits, in order to increase the components life-span. With this approach, it is possible to guarantee a stable cooling condition with different ambient temperatures and power dissipations.

Engineers based at Aavid’s plant at Bologna in Italy are available for further technical information and after sales support.
