<p>Solid state relay heatsinks are devices that provide <a href="/web/c/relays/solid-state-relays-accessories/solid-state-relays/" target="_self">solid state relays</a> with a means of dissipating heat and maintaining safe operating temperatures. All solid state relays generate heat and failure to manage this can result in the relay's failure or destruction.</p><p><h2>What are solid state relay heatsinks made from?</h2></p><p>Solid state relay heatsinks are made of high thermal conductive materials such as silver, gold, copper or aluminium. Aluminium is commonly used for its availability and low cost, typically with a black anodized finish to provide additional radiant heating dissipation. The heatsink is firmly attached to the solid state relay.</p><p><h2>How do solid state relay heatsinks work?</h2></p><p>Heatsinks have vertical fins through which hot air flows, normally assisted by a fan. The fins provide a large surface area that cools the air. Once cooled, the air is expelled into the environment, so ventilation is crucial. A heatsink's performance is measured by its thermal impedance (resistance to the transfer of thermal energy). A lower numerical thermal impedance rating means more efficient heat transfer.</p><p>When choosing solid state relay heatsinks you should bear in mind coordinating size, form factor, thermal impedance rating and mounting.</p>

Solid state relay heatsinks are used to dissipate excess heat and keep operating environments sufficiently cool for solid state relays to work efficiently.

<p>Heat sinks are required to maintain the long-term reliability and ensure the correct operation of the solid state relay. They dissipate the heat into the ambient air and away from electronic devices, maintaining a safe operating temperature. If this heat is not managed correctly this can result in the failure of the relay itself. </p><h2>What is the most effective heat sink? </h2><p>Heat sinks are made up of thermal conductive materials such as aluminium and copper, where cost is low, but conductivity is high. </p><h2>Sensata/ Crydom Relay Heatsinks Features:</h2><ul><li>DIN rail mounted, or panel mounted</li><li>Different thermal resistance ratings</li><li>Optimised performance</li><li>Single, dual and three phase solid state relay applications</li></ul><h2>Applications</h2><p>Sensata/ Crydom Relay Heatsinks can be used in a variety of industrial settings such as thermal management solutions, water systems, power plants, HVAC systems, heating and cooling and electronic systems.</p><h2>Where do you position a heat sink?</h2><p>Heat sinks must be positioned so that the hot air flow over the finned surface is maximised. They need to be positioned where air can naturally flow through your enclosure. </p>
