The communication base station equipment
is developing towards lightweight, high power and high integration.
Contrary to its volume decreasing, the heat consumption density of the
system increases to 30W/L-35W/L, while the shell generally being cast
cavity causes to adopt the passive heat dissipation method . The huge
calorific value poses serious challenge to the whole device.
5G base stations are usually installed on
the iron frame on the roof and high in the field, which requires
reducing volume and weight to favor installation.AAU and BBU in 5G
station undertake the signal conversion, processing and transmission,
this power consuption is 2.5~4 times that of 4G BTS.
The thermal management materials of Opute, like silicone thermal pad, thermal grease and thermal gel can well solve the reliability and
electromagnetic compatibility problems of AAU, RRU in 5G base station in
complex environments.
