The original design ideal of GooLED coolers comes from Pin Fin heat sinks. GooLED coolers are considered to be among the most powerful heat sink designs available today.
GooLED heat sinks have the following advantages: 1. Light-weight, lighter than the same size of traditional LED coolers. 2. High efficiency of heat dissipation comparing to the same size of star heat sinks. 3. Flexible installation options, suitable for lots of branded COB modules.

Detailed analysis of GooLED Through the above analysis of the data, Pin fin heat sinks provide very low thermal resistance values per given space and low pressure drop. The cooling capabilities of pin fins stem from the round geometry of the pins, the omnidirectional pin configuration, and the use of highly conductive materials. The smooth round pins reduce resistance to incoming air streams and enhance air turbulence between the pins. The omnidirectional structure maximizes the entrance of fresh air into the pin array and at the same time allows the hot air to exhaust from the pin array in every possible direction. The use of highly conductive materials further reduces the thermal resistance of the heat sinks. Cool Innovations has further enhanced the performance of pin fin heat sinks via the introduction of the splayed and flared pin fin designs. Their unique structure allows them to offer lower thermal resistance values and lower pressure drop per given space.
