2 Claims. (01. 98-40) The object of my invention is to provide a heat exchange unit with means for adjustably controlling the direction of the air passed through the unit in accordance with the various heights of the room in which the unit is placed, with particular'reference to a unit forcing the air downward from the ceiling.
Another object of my invention is to provide adjustable means whereby the air may be spread of Figure 1.
Figure 3 is a front elevation of the unit.
Figure 4 is a plan view taken on the lines 44 of Figure 3.
Referring to the aforesaid figures, I is a circular heat exchanger comprising fins ll mounted on heat tubes I2, and is supported between an upper casing l3 and a lower casing H. A motor I5 is mounted on the casing l3 and actuates a fan I6 which draws air through the inlet I I, through the heat exchanger and forces the air out preferably-downward through the outlet l8 in the lower casing H. Below the fan and in the path of the emitted air are a series 'of vanes 20 supported and positioned by rods I! which are attached at one end to the lower casing ll by nuts 2| and at the other end to a circular web 22 by nuts 23. Each vane 20 corresponds to a segment of a frustum. If the vane is curved, it would correspond to the segment of a frustum of a cone and if flat to the fmsturn of a pyramid. When all the vanes are placed together with edges proximate the edge of the nearest vane, the
form approximates that or a irustum. The center of each vane is pivotally attached to circular web 22 as at the point 24 and to an interior circular web 25 at the point 28 so that the vane 20 may pivot on an axis formed by the line from 24 to 26. The circular web 25 also forms a circular opening which causes an asplrating effect varying with the position 01 the Vanda. When the deflector is in the formof a frustum of a cone, air moving over the surface of the cone will induce secondary air upward through the cone, which is designated as an aspirating effect, and which diminishes as the vanes are moved out of the form of the fr'ustum. When the vanes 20 are in a common plane, they form with each other a frustum of a cone which has the effect of directing the air laterally, which is particularly useful when the device is installed in rooms with low ceiling heights and a lateral flow of air is desired to prevent drafts.
vary the amount of lateral deflection or to have no deflection, in which case the vanes may be pivoted individually on their axis so as to vary the amount of deflection or as to allow'substantially no interference with the flow of air from the fan IS without aifecting the fan performance.
I claim:
-1. An outlet for unit heaters comprising an inner hollow web and a larger outer web, movable vanes attached to said webs, said vanes in a closed position forming the surface plane of a frustrum of a, hollow cone, said vanes being pivotally attached to said webs as'to allow movement of said vanes out of said plane, the said inner web being centrally positioned in the path of the discharge air of the unit heater and spaced closer to the unit heater than the said outer web,
closer to the unit heater than the said outer web,
rods supporting and spacing the outer web from the unit heater, whereby secondary air will be induced upward through said inner web when said vanes are in a closed position and whereby the volume of said secondary air will be varied when the said vanes are moved out-or said plane.
