Indirect cycling involves thermal exchange outside of the core.

Inside the mask is a patented system of copper coils that its manufacturer calls a thermal exchange device.

Large circulation and thermal exchange units (also built locally) were installed around the edge, helping to maintain the required climate inside.

The thermal exchange occurs via a cluster of 144 boreholes, drilled 37 metres into the earth.

Grain heating by thermal exchange is very important in supernova remnants where densities and temperatures are very high.

These effects correspond to a large hysteresis from the thermal exchange with the environment and a smaller hysteresis due to internal friction within the rubber.

This fall, the Stanford football team and the San Francisco 49ers began using Rapid Thermal Exchange (RTX), a new cooling system for athletes invented by two Stanford scientists.

The aft section was an engine house, with a small ancient thermal exchange furnace, and a couple of time-expired electric motors used by the McBoeing's in their flap actuators which the captain had salvaged from the spaceport.

For this, the steam recovered from the turbines was used inside the heating tanks, thereby provoking a thermal exchange and obtaining a temperature of 130 C. At this temperature, the only thing that remained was to get the water to a certain pressure before directing it to the boilers.
