Remote Radio Unit-RRU 5G Heatsink systems are using natural convection cooling due to some outstanding advantages such as low cost, high reliability, noiseless operation, and hard environment operation. However, some main disadvantages such as a relatively low heat transfer and low heat dissipation density are to be solve by optimal heat sink fin design. This paper describes an optimal heatsink fin profile design with V shape angle to maximize natural cooling for RRU 5G embedded heat pipe and vapor chamber technology. Several core ICs of RRU 5G with high heat loss sources up to hundred W are embedded copper plate and heat pipe. Temperature measurements were carried out to validate the RRU 5G 8T8R heatsink modeling and experimental methods.
