Abstract
An electronics pressurization system includes a compressed air source providing pressurized air, a manifold, and a case containing a first high-voltage electrical system, the case comprising a pressurizable vessel and a vent hole. The compressed air source is connected to the manifold, and the manifold is connected to the case. The compressed air source provides a flow of pressurized air, via the manifold to the case to maintain an air pressure in the case at a higher-than-ambient pressure.
Claims20
An electronics pressurization system comprising:
- a compressed air source providing pressurized air;
- a manifold;
- a case containing a first high-voltage electrical system, the case comprising a pressurizable vessel and a vent hole;
- wherein the compressed air source is connected to the manifold, and the manifold is connected to the case;
- and
- wherein the compressed air source provides a flow of pressurized air, via the manifold to the case to maintain an air pressure in the case at a higher-than-ambient pressure.
A method of pressurizing electronic systems at altitude, comprising:
- obtaining, at a system comprising a compressed air source, pressurized air from the compressed air source;
- determining whether one or more threshold conditions for pressurizing a case containing an electronic system is met;
- and
- responsive to determining that the one or more threshold conditions for pressurizing the case containing the electronic system is met, pressurizing the case by to a higher-than-ambient pressure by providing a flow of pressurized air from the compressed air source to the case, via a manifold;
- wherein the case comprises a pressurizable vessel and a vent hole;
- and
- wherein the compressed air source is connected to the manifold, and the manifold is connected to the case.
