Electrical/electronic equipment e.g. actuator control box, cooling device for turbomachine, has vortex tube comprising inlet connected to element of turbomachine, and fresh air outlet connected to heat exchanger

摘要

The device has a double circuit type vortex tube (14) i.e. ranque tube, comprising an inlet (18) connected to an element (16) e.g. low pressure compressor of turbomachine (10), and a cool air outlet (24) connected to a heat exchanger (50). The outlet of the tube is connected to an inlet (34) of a secondary circuit of the heat exchanger. The tubes supplies, at the outlet, cool air whose temperature is 50 degree Celsius lower than the temperature of pressurized air supplied at the inlet (18).
