HEAT PIPE COOLED TURBINE CASING SYSTEM FOR CLEARANCE MANAGEMENT

摘要

PROBLEM TO BE SOLVED: To provide a heat pipe cooling system for clearance management in a turbine.SOLUTION: A turbomachine includes a compressor configured to compress air received at an intake portion to form a compressed airflow that exits into an outlet portion. A combustor is operably connected with the compressor, and the combustor receives the compressed airflow. A turbine is operably connected with the combustor, and the turbine receives a combustion gas flow from the combustor. The turbine has a turbine casing. A cooling system is operatively connected to the turbine casing. The cooling system includes a plurality of heat pipes attached to and in thermal communication with the turbine casing. The plurality of heat pipes are operatively connected to one or more manifolds. The plurality of heat pipes and the one or more manifolds are configured to transfer heat from the turbine casing to a plurality of heat exchangers.SELECTED DRAWING: Figure 1
