the upper body 14 to align and secure the upper body 14 to the lower body 16 as is best depicted in fig2 the inlet fins 36 preferably extend above an upper edge 38 of the base 24 to collectively define a containment area for the fan 18 as described in more detail below the fluid exhaust 34 is in fluid communication with the fluid intake 32 via the hollow interior 30 of the base 24 and is defined by a gap or space between the base 24 and the surface 11 upon which the device 10 is positioned disposed within such gap is a plurality of exhaust fins 40 which protrude from a lower surface of the base 24 like the fins 36 the fins 40 extend from the base 24 in a direction generally parallel to the lower axis 27 the fins 40 are disposed in spaced relation to each other preferably at equidistant intervals and are sized and arranged to be rested directly upon the surface 11 to support the base 24 in spaced relation to such surface 11 in this regard the fins 40 preferably each include a distal edge or surface such distal surfaces residing on a common plane the fins 40 additionally facilitate a more even air distribution over the underlying surface 11 when the device 10 is in operation in an exemplary embodiment the upper body 14 and lower body 16 have a combined height of approximately.
