Abstract
A heater of a piece of aeronautic equipment is intended to be arranged at the skin of an aircraft. The equipment includes a part intended to be arranged at the skin of the aircraft and elements for heating the part. The heating element include a thermodynamic loop including a closed circuit in which a heat transfer fluid circulates, the closed circuit including an evaporator and a zone in which a condensation of the heat transfer fluid can occur in the appendage to heat it. Outside the evaporator, the circuit in which the fluid circulates is formed by a tubular channel with an empty section. At least part of the equipment is made from a material with a low heat conductivity.
Claims12
A piece of aeronautic aircraft equipment, the equipment comprising:
- at least one part arranged at a skin of the aircraft;
- a heater that heats the part, said heater comprising a thermodynamic loop comprising a closed circuit in which a heat transfer fluid circulates;
- and
- a single material having a heat conductivity gradient,
- wherein:
- the closed circuit comprises an evaporator and a zone in which condensation of the heat transfer fluid occurs in an appendage to heat the zone,
- outside the evaporator, the circuit in which the fluid circulates is formed by a tubular channel with an empty section, wherein no porous material is present in the tubular channel, and
- at least the part of the equipment is made from the single material, the single material with a heat conductivity at 50° C. below 100 W/m·K.
