Water Blocks

Water Blocks

Water blocks ( liquid cold plates ) are the most efficient method of heat removal. They are often 4-5 times more efficient compared to a standard air cooled heat sink and fan. The principle is simple: you provide a source of cool liquid (typically water, or ethylene glycol/water, or Fluorinert) to the inlet of the water block. The liquid travels back and forth through the various chambers of the water block thereby absorbing the heat from the TECs or power electronics. The warmer liquid then exits the water block. The source of the liquid can be;

    • Building (tap) water - This water is usually cooler than the ambient air temperature. The warmer exiting water can be sent to a drain or re-used in a number of ways.
    • Chiller Liquid - A pre-chilled Liquid (typically alcohol, water/glycol, oil, or a dielectric fluid such as Fluorinert) from a recirculating chiller passes through the water block and then is returned to the chiller for re-cooling. This source typically is a closed loop sytem.
    • Well water, lake, or stream water - This water usually requires pre-filtering but can be substantially colder than ambient air temperature, especially during winter months. Exiting water can either be returned to the source or re-used.
    • Radiator closed loop - a liquid (water, propylene glycol, or a mix of both) enters the water block at approximately ambient air temperatures. The exiting warm liquid then goes to a fan cooled radiator of sufficient size to cool the liquid back down to ambient air temperature. The liquid is then sent back through the water block, This is a closed loop system.

Liquid cooling plates ( Water Blocks ) are used as a cooling solution for TECs, TEGs, IGBTs, thyristors, SiC, data centers, EV/HEV, alternate energy, battery systems, power electronics and anything that needs a compact highly efficient means of heat removal.
