AI Technical Summary

Technical Problem

In existing amplifier designs, the heat dissipation efficiency of the core heat source inside enclosed equipment is low. This is mainly due to the redundancy of the airflow conduction path, the thermal resistance effect of the wall, and the local turbulence dead zone, which causes the heat to attenuate layer by layer during the migration process, making it impossible to efficiently and directionally dissipate the heat.

Method used

The graphite blocks are tightly attached to the surface of the heating element for zero-gap heat conduction. Combined with graphite fins and heat-conducting copper pipes, a three-stage linkage heat dissipation structure is formed. By utilizing the high thermal conductivity and natural convection of graphite material, and in coordination with the circulation of heat-conducting fluid, rapid heat transfer and even distribution are achieved.

Benefits of technology

It significantly improves the amplifier's heat dissipation speed and overall efficiency, reduces the risk of local overheating, and ensures the stability and reliability of the equipment under various operating conditions.
