Patent ID: 8197136

Claim:
A tomography apparatus comprising: an apparatus frame having an interior containing heat-generating components; a flow-generating arrangement in said interior of said apparatus frame that generates a flow of air within said interior of said apparatus frame to convey heat away from said heat-generating components; a ventilation element mounted at said apparatus frame and having a passage therein that communicates the interior of said apparatus frame with an exterior of said apparatus frame to allow air flow through said ventilation element between an intake window of said ventilation element, located in said interior of said apparatus frame, and a discharge opening of said ventilation element located at said exterior of said apparatus frame; and said intake window comprising a middle region and respective side regions on opposite sides of said middle region, said side regions having an effective air intake cross-section that is larger than an effective air intake cross-section of said middle region in order to produce a substantially uniform flow profile of air at said discharge window of said ventilation element.
