    摘要: An enclosure covers equipment to be camouflaged from thermal or multi-spectral (thermal, radar visual) detection in spaced relation with the equipment. The enclosure is preferably semi-transparent plastic material sufficiently spaced from the equipment to permit natural convection, or forced airflow over the equipment. In one embodiment, the plastic material has a number of sides with a plurality of openings formed therein for entraining air and a top joining the sides. A chimney is formed in the top and an adjustable discharge damper is provided in the chimney for controlling the flow of air over the equipment. The airflow may be natural or controlled actively or semi-actively.
