The use of aluminum heat
sinks in critical product cooling systems brings enormous benefits for
industrial and commercial electronic device manufacturers. Aluminum heat sinks
for cooling application is a perfect combination of greater strength and
lighter weight. Extruded shapes generally have a greater tolerance than
machined parts, and aluminum has a higher strength-to-weight ratio than steel,
brass or copper.
Aluminum alloy is very malleable and,
consequently, aluminum heat sink extrusion profiles can be created in a wide
variety of unique designs. Aluminum is a good heat conductor and a good heat
reflector, making it very useful in heat transfer applications and as a highly
reflective heat shield. Aluminum alloy can be made in various tempers and is
relatively low in cost.
While aluminum may provide less thermal
conductivity than other more efficient cooling metals, such as copper, those
metals are far more difficult to extrude or work into heat sink application
profiles in comparison to aluminum. It is also considerably easier to create
custom aluminum heat sink profile variations. When extruded in a fin, for
example, profiles can easily be attached to a copper base, conducting a large
amount of thermal energy to the lighter, less expensive aluminum alloy cooling
fins.
Wangfa Technology designs and manufactures
aluminum heat sinks to serve the telecommunications, electronics，electric appliances and computers.
