Abstract
A heat pipe heat exchanger in which heat is transferred from hot fluid in duct 12 to cold fluid in duct 14 by a continuous cycle of evaporation and condensation of a liquid contained in heat pipe 26. Should the heat pipe not function properly, the transfer of heat to that portion of the heat pipe lying in the duct for cold fluid will be reduced partially or completely. This reduction in temperature at the end of the heat pipe lying in the duct for the cold fluid is immediately sensed by a thermocouple 54 and indicated upon a gauge 56 which is adapted to identify a particular heat pipe. Repair or replacement of a faulty heat pipe will return each heat pipe to its maximum effectiveness.
