Aluminum Cold Forging Cylindrical Heat Sink

Cold forging heat sink is made by cold forging technology which is a highly precise process, the heat sink is manufactured by a punch machine which is under the high pressure and low temperature, this technology enables no air bubble and impurities in the heat sink body and makes the heat sink has a strong strengh. Aluminum cold forging cylindrical heat sink usually has round pin fins which is difficult to be extruded, and machining the fins costs too much, cold forging technology allows the round pin fin heat sinks possible for the electronic industry.

Cold forging is a technical process for forming and forging profiles which under the recrystallization temperature (generally, room temperature). Most of the cold forging materials are aluminum alloys, copper alloys with low deformation resistance and good plasticity at room temperature. Cold forging can cause work hardening (strain hardening) of the profile during processing, which can increase the strength and hardness.

The cold forging process is widely used by heat sink manufacturers for the production of light source heat sinks and LED heat sinks. Sinda Thermal is an early manufacturer of cold forging to manufacture heat sinks, and has accumulated rich experience in cold forging technology. In addition to the production of general light source radiators, Sinda Thermal has reserved and manufactured high-power cold forging radiator technology to solve the problems of poor thermal conductivity of die-casting microchannels and high cost of machined microchannels. In water cooling schemes such as motor controllers.

The Aluminum Cold Forging Cylindrical Heat Sink uses cold forging technology for integrated design and production, with low thermal resistance and good thermal conductivity, effectively ensuring that heat is transferred in time and achieving the ultimate heat dissipation effect. In addition, cold forging heat sinks have good mechanical properties, high productivity and high material utilization, and are especially suitable for mass production, thereby reducing production costs.

The benefits of aluminum cold forging cylindrical heat sink

1, Usually the material for cold forging process is AL1050 or AL1070 which have better thermal conductivity than AL6063, which means the cold forging heat sink has a better thermal performance than extruded heat sink or die casting heat sink.

2, The round fins in heat sink creates more surface area to dissipate the heat, and for cold forging process which has less fin density and ratio aspect as extrusion, which enable the cold forged heat sink can dissipate more heat per unit time. Also the fins and base is intergrated which has no interface joint between them, so the heat can be conducted to the fins rapidly as the thermal resistance is very low.

3, The process has a very high production rate and yield which can offer a low manufacturing cost.
