You can find heat sinks made from different aluminum alloys. The most common alloys used include 6000 aluminum series. They are durable and affordable too.
Get PriceThe liquid cooled heat sink is highly efficient and behaves like an isothermal block which is easily modeled. For consistency throughout this paper the term aluminum evaporator heat sink refers to the aluminum evaporator on the heat pipe assembly that directly sinks heat from the package. Likewise the term copper block heat sink refers to ...
Get Priceheat pipe cooling) in power electronics. At the core was a heat sink of salt hydrate PCM impregnated within the foam. The sink with its current specifications (with liquid cooling) was able to absorb a thermal load consistent from a group of 4-5 IGBTs which dissipated a low power of 20W per module during stops. The heating period of 1600-

Get PriceA heat sink and method for gaseous cooling of superconducting power devices. Heat sink is formed of a solid material of high thermal conductivity and attached to the area needed to be cooled. Two channels are connected to the heat sink to allow an inlet and an outlet for cryogenic gaseous coolant. Inside the hollow heat sink are fins to increase metal surface in contact with the coolant.

Get PriceThe steady‐state rate of heat loss from the steam becomes 1 2 120.7W (per m pipe length) R T T Q total The total heat loss for a given length can be determined by multiplying the above quantity by the pipe length. The temperature drop across the pipe and the insulation are: Q R W C W C
Get PriceAnother material that's gaining popularity with heat sink producers is a natural graphite composite material. It's not as conductive as copper but it's close with a thermal conductivity of 370 W/mK. But the real advantage of graphite is its weight -- it weighs just 70 percent of the weight of aluminum.

Get PriceThe increased conductivity is attributed to the exceptionally high thermal conductivity of heat pipes. Heat pipe operation is illustrated in Figure 1. Heat pipes operate by vaporizing the working fluid at the heat source or evaporator end moving the vapor by internal pressure difference and condensing at the heat sink or condenser end.
Get PriceHeat extracting methods include active and passive heat sink cooling thermoelectric cooling water cooling heat pipes and phase-change cooling. Every method has its advantages and disadvantages. Passive cooling using plate fin sinks is a fail safe and quiet method that …
Get PriceAluminum nitride (AlN) has been widely used as a heat sink material in conduction-cooled superconducting coils but is hard to process. We have therefore developed an easily processed Dyneema-fiber-reinforced plastic (DFRP) with high thermal conductivity.
