Solution Approach 2:

The heat pipe acts as a thermal intermediary that efficiently conducts heat away from the radio module to the cooling fan housing structure. This thermal mediation prevents heat accumulation in the chassis, thereby eliminating safety risks associated with high chassis temperatures while allowing the radio module to operate at high power

Inventive Principle:

Principle #24Intermediary (Mediator)
