Product Advantage
140mm pin heatsink

140mm Pin Heatsink advantages:

1. 140mm pin heat sink is cold forged heat sink which made of pure aluminum, and it has high thermal conductivity and rapid cooling, thermal conductivity is 226W/M.K, conduction effect is obvious.

2. Outer diameter of bottom base is 140mm Scientific layout, reasonable structure, Circular progressive layout with equal proportions, 3mm cylindrical heat sink, evenly distributed,Reasonable structure, durable mold,Same gap, good air flow.

3.The thickness of the bottom plate is 10mm and the height of the column is 60mm; Integrated structure, low thermal resistance, high efficiency; Small temperature difference of conjoined structure, controllable temperature difference of the whole; Compatible with multiple surface treatments, color customization.

Technical Process

Metals minimum recrystallization temperature/℃
Copper (Cu)
Aluminum (Al)

Cold forging technique has been widely used by heat sink manufacturers in the production of led light heatsink. We have resolved the problems such as the low thermal conductivity of die-casting micro-channels and higher costs for machining micro-channels. We have already applied our expertise to cooling solutions including high-voltage inverters, wind power converters, and electric motor controllers.
