Multi-purpose module TM 71-1.0-4.0 is a rather powerful 20 x 20mm cooler intended for use with 5 to 8.6 volt (DC) power sources. Its compact size, excellent cooling capacity and relatively low heat ejection, make the module particularly popular for spot cooling.

Can be used with a very wide variety of economical extruded heat-sinks without the hot-side temperature becoming unreasonably high. It’s also frequently used in strings. For example, two connected in series can be operated from a 12V source (or 15V). Four in series are operated with a 24V source, etc. A combination of parallel strings of modules in series allows coverage of a large surface area.

TM 71-1.0-4.0 may be used for cooling, heating and thermal stabilization and is employed in a wide range of applications including electro-optic/photonic, fiber optic, aerospace/military, telecommunications. A version for thermal cycling is available.

Available with metalized and tinned surfaces.
