<p>A device for improving thermal transfer inside an ultrasound probe and reducing heat build-up near the transducer face. The cable components (40) are used as heat pipes which conduct heat out of the probe handle (14). These heat pipes are coupled to an internal heat pipe (36) which is in heat conductive relationship with the transducer pallet (2). Thus, heat generated by the transducer array can be transferred, via the internal heat pipe plate and the cable heat pipes, away from the probe surface which contacts the patient. A heat conductive structure can be embedded in the overall shield braid of the cable (16). Suitable heat conductive structures include thread or wire made of material having a high coefficient of thermal conductivity, as well as narrow tubing filled with heat conductive fluid. Alternatively, inlet and return flow paths for cooling fluid are incorporated in the cable. The inlet and return flow paths inside the cable are respectively connected to the inlet and outlet of a flow path which is in heat conductive relationship with the heat pipe in the probe handle. <IMAGE></p> |
