Circuit Board Coolers

Also known as thermal pads and thermal interface pads, these heat-dissipating pads pull heat away from electronic components.

Heat Sinks

Adhesive-Mount Heat Sinks

Remove excess heat by sticking these heat sinks onto circuit boards, semi-conductors, relays, and other heat-sensitive electrical components.

Clamp-On Heat Sinks for Pipe and Tube

Turn your pipe or tube into a heat sink.

Clip-On Heat Sinks

Clip these heat sinks onto circuit boards, semiconductors, and other heat-sensitive electrical components.

Heat Sinks for Water

A fan cools water as it moves through the tubes.

Heat Sinks with Internal Pump for Water

To provide a more consistent flow of cooled water than other heat sinks for water, these have a built-in pump and reservoir.

High-Capacity Heat Sinks for Oil

For greater cooling capacity and higher flow rates than other heat sinks for oil, these have a large fan.

Heat Sinks for Oil

Dozens of fins and coolant tubes quickly dissipate excess heat.

Heat Transfer Pads

An alternative to heat transfer compounds, these soft, flexible pads transfer heat from a source to a heat sink.

Spreaders

Evenly distribute ice-melting products and other small particles with these spreaders.

Hand-Held Spreaders

Turn the hand wheel to spread ice-melting products and other small particles.

Vehicle-Mount Spreaders

Evenly scatter large amounts of ice-melting products with these spreaders.

Heat-Transfer Tape

Quickly conduct heat away from electronic components. Kapton® polyimide gives this tape excellent electrical isolation.

Thermally Conductive High-Temperature Silicone Foam Sheets

Thermally Conductive High-Temperature
Silicone Foam Sheets

Protect sensitive equipment from heat buildup with this silicone foam. These sheets are commonly used to fill gaps and damp vibration in computers, battery installations, and pipe assemblies.

Heat-Transfer Foil

Made of indium, this foil is more thermally conductive than thermal interface materials (TIMs) made of plastic.

Heat Gun Nozzles

Flat-Tip Heat Gun Nozzles

Create a wide airflow that’s good for drying and stripping paint.
