1. An immersion cooling system comprising:
a catch pan;
a heat-generating electronic device;
a housing positioned around the heat-generating electronic device such that the heat-generating electronic device is at least partially enclosed within the housing, wherein an exterior of the housing defines an angled projection that extends from a bottom surface of the housing to form a drip point structure positioned above the catch pan and wherein the exterior of the housing is configured to guide leaking working fluid from the housing, along the exterior of the housing through cohesion to the drip point structure to drip from the drip point structure and fall directly into the catch pan;
a fluid reservoir in fluid communication with the housing and configured to provide a working fluid to the housing; and
a fluid pump configured to circulate the working fluid from the catch pan to the housing.
