The Skived fin, also known as skiving technology, simply takes an entire piece of aluminum or copper and use special skived machine to cut out fins with standard spacing and a certain thickness and height. Because of using high precision cutting technology, the integration of the forming, relative to other processing technology, the same volume of raw materials can be cut out more heat dissipation area, the heat transfer performance is more stable, in the same condition,the cooling performance is more than 1.5~2 times of the efficiency of traditional bonded fin or soldering heat sink, thus greatly improve heat dissipation efficiency and extend the service life of heating components.
Lori company adopts precision skived fin process manufacturing heat sink. Because it is used the whole cutting forming, heat collection being one piece with the heat dissipation plate, which makes the heat directly from the endothermic base plate to heat collection efficient transmission. It can be in area of cutting out more heat per unit area (compare traditional extrusion process heat dissipation area can be increased by 30% – more than 50%). With its unique production process makes the collection form a smooth and pits to contact with the air of fin area is larger. Thoroughly overcome the traditional welding technology and insert process caused by the thermal resistance of medium, thereby further up the heat conduction efficiency. This technology made it thinner than traditional and spacing is smaller, which makes the minimum spacing can be as thin as 0.20mm. So as to avoid the accumulation of heat in the heat sink, which allows the heat to take away quickly, thus significantly improving the heat tranfer effect.
Skived heat sink has the following advantages:
(1) Skived heat sink is a whole profile without any connection point, which can give full play to the heat dissipation characteristics of the profile.
(2) Lori’s skived fin process can make the skived fin more thinner and denser, with higher heat transfer efficiency.
(3) The skived fin processing technology is simpler than other liquid cooled heat sink, with lighter weight and lower cost.
(4) Compared with aluminum extrusion and other processes, it is less limited in size and can be made wider, which can be used for heat transfer of machines with large power
Skived fin are mainly suitable for industries with high thermal density and high power dissipation requirements, which are widely used in power, medical, communication, industrial control and server industries. With the large-scale applications, LORI ’s skiving technique becomes more mature and the coverage of this technique has been increased. With the gradual enhancement of the degree of automation, we demonstrate the apparent advantage from the aspects of cost and reliability. We have received the endorsement from various domestic and overseas customers.
