Abstract
A system includes a heat exchanger, a heated fluid source, a sensor configured to collect data about a coolant in the heat exchanger, and a decongealing assembly arranged to provide heated fluid from the heated air source to one of the heat exchanger or a location upstream of the heat exchanger based on the data collected by the sensor.
Claims20
A system, comprising:
- a heat exchanger;
- a heated fluid source configured to generate a heated fluid;
- a sensor configured to collect data about a coolant in the heat exchanger;
- and
- a decongealing assembly arranged to provide the heated fluid from the heated fluid source to one of the heat exchanger or a location upstream of the heat exchanger based on the data collected by the sensor, wherein the decongealing assembly comprises a first chamber, an assembly heat exchanger upstream from the first chamber, and a second chamber upstream from the assembly heat exchanger, and wherein the heated fluid is different from the coolant.

A method for decongealing a heat exchanger, the method comprising:
- receiving data indicative that a coolant is congealed in a coolant channel extending through the heat exchanger;
- providing, to the heat exchanger or to a location upstream of the heat exchanger, heated air from a heated fluid source that is a component of a gas turbine engine;
- receiving second data indicative that the coolant is no longer congealed;
- and
- ceasing flow of the heated air from the heated fluid source.
