Abstract

The invention discloses an aircraft equipment compartment heat dissipation system and a heat dissipation method thereof, belongs to the field of aircraft heat dissipation, and solves the problems that an existing aircraft electronic equipment compartment is serious in heating, low in heat dissipation efficiency and insufficient in heat dissipation. The heat transfer structure is arranged between the radiator and the electronic equipment cabin for heat conduction, heat of the electronic equipment cabin is transferred to the radiator, then the low-temperature fluid in the engine flow channel is guided through the heat dissipation air inlet channel to flow through the radiator, the radiator is cooled through heat exchange between the low-temperature fluid and the radiator, And the heat is discharged out of the aircraft cabin through the heat dissipation air outlet channel, so that the heat dissipation of the aircraft electronic equipment cabin is realized.

Description

technical field [0001] The invention relates to the field of aircraft heat dissipation, in particular to an aircraft equipment compartment heat dissipation system and a heat dissipation method thereof. Background technique [0002] With the rapid development of modern weapons, the development trend of modern military aircraft is in the direction of informatization, miniaturization and integration. The increase in the power density of equipment in the aircraft electronic cabin puts forward higher requirements for the heat dissipation of the aircraft electronic cabin. Traditional heat dissipation methods based on radiation, heat conduction and natural convection can no longer meet the heat dissipation requirements of modern aircraft electronic equipment compartments. Contents of the invention [0003] In view of the above analysis, the present application aims to provide a heat dissipation system and heat dissipation method for aircraft equipment compartments, which solve th...
