This 40mm (L) x 40mm (W) x 20mm (H) extruded aluminum heatsink kit is specially designed for Cooling 3D Printer, NEMA 17, TEC1-12706 Thermoelectric Peltier Modules. This set of heatsink height is 20mm. This kit is made from 6063-T5 aluminum alloy with high thermal conductivity 201 W/m.K, structure stability and light weight. The heatsink extrusion is in vertical and horizontal grooves; that is greatly increases the heat dissipation function. The surface of extruded aluminum is anodized in black. This kit of heatsink comes with 40x40mm pre-applied thermal conductive double sided adhesive tape, for easy installation and optimum heat conductivity.
