Wellbore wireless thermal conductivity quartz transducer with waste-heat management system

A wellbore wireless thermal conductivity quartz transducer system comprising a thermal conductivity quartz transducer and a wireless communication system including an external device and an internal device, a cable, and a surface device, wherein said thermal conductivity quartz transducer and said external device are configured to be arranged outside a wellbore conduit, and said internal device and said cable are configured to be arranged inside said wellbore conduit, wherein said thermal conductivity quartz transducer comprises;

• a first quartz resonator configured to provide a first temperature signal representing an ambient temperature of said thermal conductivity quartz transducer;
• a heat dissipation element configured for being in thermal connection with a fluid;
• a second quartz resonator configured for providing a second temperature signal representing a dissipation temperature of said heat dissipation element;
• an electronics circuit;
• and
• heat guiding means arranged for transferring a heat generated by said electronics circuit to said heat dissipation element, so that said dissipation temperature is higher than said ambient temperature, wherein said wellbore wireless thermal conductivity quartz transducer is arranged to transfer said first and second temperature signals, to said surface device via said wireless communication system and said cable;
• wherein said cable is arranged for transferring electric power to said internal device, said internal device is arranged to provide inductive power to said external device, and said external device comprises power means for power harvesting said inductive power and for providing power to said electronics circuit.
