Adhesive-Mount Heat Sinks

Remove excess heat by sticking these heat sinks onto circuit boards, semi-conductors, relays, and other heat-sensitive electrical components. They mount using a thermal tape, which makes the heat sink more effective by increasing the heat transfer. The tape also simplifies setup since you don’t need fasteners or to wait for epoxies to cure. Because they're pin style, air can flow around the pins in any direction, which means you get the same heat transfer without needing to determine the airflow direction before mounting.

Thermal resistance is a measure of how difficult it is for a heat sink to transfer heat. The lower the thermal resistance, the more effectively it dissipates heat.

Clamp-On Heat Sinks for Pipe and Tube

Heat Sink Shown Open

Heat Sink Shown with Pipe

Turn your pipe or tube into a heat sink. A hinged design makes these heat sinks simple to wrap around an existing line—no need to cut into your line and drain the liquid to install a heat sink. Multiple fins create a large surface to draw heat away quickly. As they cool down the contents of your line, they heat the space around the heat sink, similar to how radiant heat works.

Secure them together with the included fasteners. You don't need to worry about using heat transfer compounds or putty with these.

Cooling capacity is based on 180° F water flowing through your line at one gallon per minute in a space with an ambient temperature of 65° F and normal airflow.
