forging heat sink

详情

 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
• Googe 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
Forging:
• The Cold Forging process is used in the manufacturing of the majority of Googe heat sinks
• The process ensures that no air bubbles, cavities or any other impurities are trapped within the material
• The cold forging process allows for the use of highly conductive copper and aluminum alloys
• Aluminum pin fin heat sinks are forged from pure aluminum (AL***0)
• The thermal conductivity of AL ***0 is ***0 btu/in ft2 hr of. (~*0% higher than AL **0, a common cast alloy)
• Copper pin fin heat sinks are forged from pure copper (CDA **0)
• The thermal conductivity of CDA **0 is ***2 btu/in ft2 hr of. (~**0% higher than AL **0, a common cast alloy) Benefit:
•Complete in one piece with no interface.
•High aspect ratio 1: **0
•Can forge aluminum alloy, pure aluminum and copper
•No taper fin shape improves airflow smooth through
•High material density increases thermal conductivity
 •Wide range geometry as die casting
