In
practical using, improving the heat dissipation for LED display not
only effectively increases
heat dissipation but also achieves
power - saving effect, which are more conducive to improving the
service life of LED display screen. Here
are 7 tips to improve heat dissipation of Led display screen.
1.
Using fans to heat dissipation. The internal lamps adopt long
lifespan fans to strengthen the heating dissipation. This is a common
method and it is low cost, more efficiency.
2.
Using aluminum fin heat dissipation. This is the most common way to
heat dissipation, use aluminum cooling fins as part of the shell to
increase the thermal area.
3.
Using the theory of air fluid dynamics. Adopting the light hull shape
to producing convection air, which is the lowest - cost way to
strengthen the heat sink.
4.
Surface radiation heat treatment, is a relatively simple application
of radiation thermal paint, you can heat radiation from the surface
of the lamp shell.
5.
Thermal Conductivity of thermal integration--Application of ceramics
with high thermal conductivity. LED lamp shell heat sink is aim to
reduce the HD chip temperature. Owing to LED chip expansion coefficient
has great difference with mental expansion coefficient and expansion
coefficient of heat-sink materials, so LED chips cannot be welded
directly to avoid high and low temperature thermal stress
damaged LED display chips.
6.
Using heat pipe for heat dissipation. Adopt heat pipe Technology,
guiding the heat of LED display chips to shell cooling fins.
7.
Making thermal conductivity in plastic case, filling thermal
interface material at the time of injection molding so as to increase
the heat conductive & cooling
capability of plastic shells.
