Description

Technical Field

[0001] The utility model relates to the technical field of diode boxes, in particular to a heat dissipation type diode box for helicopters. Background Art

[0002] When a helicopter is in flight, its electronic equipment will generate a lot of heat. In order to ensure the normal operation of these electronic equipment, these devices need to be effectively cooled. On helicopters, diodes, as a common electronic component, will also generate a certain amount of heat during their operation.

The diode box shell and the diode box fixing bracket form a diode box body. A detachable diode circuit board is arranged in the diode box body. Circuit board fixing brackets are provided at both ends of the detachable diode circuit board. One end of the circuit board fixing bracket is fixed to the diode box fixing bracket, and the other end fixes the detachable diode circuit board. A detachable diode mounting base and guide rails are arranged under the diode box body.

The diode box is provided with heat dissipation holes, but under high-load working conditions, these heat dissipation holes may not be sufficient to effectively dissipate the heat generated inside to the external environment. During long-term high-load operation, heat accumulation may occur inside the diode box, which may easily cause damage to the components inside the diode box. Summary of the Invention
