An adjustable air guide includes a first hollow element located adjacent to an aperture in a wall of an enclosure to allow air to pass freely there through. At least a first rigid adjustable rigid hollow pipe, a first hollow elbow, a second rigid adjustable hollow pipe, and a second hollow elbow are connected together in that order such that the first rigid hollow adjustable pipe is partially coextensive with and adjustably telescopes with the first hollow element and the first hollow elbow and second rigid hollow adjustable pipe is partially coextensive with and adjustably telescopes with the first and second hollow elbows such that the first and second rigid adjustable pipes have lengths which are effectively adjustable within a predetermined range. In addition, the rigid adjustable hollow pipes and hollow elbows and hollow first element may be arranged so as to rotate with respect to one another. A second hollow element is connected to the second elbow and is disposed adjacent to a heat generating element and a heat moving device is provided for moving air between the aperture and the heat generating element.
