1. Refrigerators coolants--- heat is transferred from food to coolant, heated coolant rises and transfers heat to air by EVAPORATION; then coolant goes back to down and repeats cycle.
2. Car engines--- engine heat goes to water, and water heat transfers heat to air via the radiator(fan) by EVAPORATION
3. Nuclear Power Stations--- heat in power generation transferred to water, heated water goes into sea or EVAPORATED into air
