Application filed January 24, 1925, Serial Ito. 4,575, and in Germany October 31, 1924.
Cars driven with very high speed, need motors with very great efficiency. The use of internal combustion engines for propulsion involves the employment' of radiators of very great area. According to this invention a new cooling arrangement is pro.
/7 In this equation It represents the necessary cooling area in sq. ems. for the loss of heat of l centigrade calorie per hourat a speed r of 'v kins/hour. From'the reciprocal value 0 w v 20- 0.4445 only increases 1.43 times.
In the case of a high speed car, which has its outer surface of streamline-form, the
' air streams smoothly over the surface, but
immediately in contact with it is dragged a layer of turbulent air (Prandls theory), the velocity of which relative to the car increases very rapidly, with the distance from the car.s surface. In this invention the cooling air is taken from this slowly moving layer in which exists very much turbulence, whereby the cooling eifectis very much increased. This layer has not the same thickness at every point of the surface, but the air streaming along the surface is always addlng to the turbulent layer fresh particles of air, so that this layer becomes thicker and thicker towards the rear of the car, particularly if the latter tapers to the rear. The cooling air aecordmg to the preferred embodiment of this mvention, is taken from the rear part, where the turbulent layer is thickest.
Referring to the drawings illustrating our lnventlon Fig. l is a diagrammatic representation of the flow of air over a moving stream-line body of the type to which my invention relates, and in which the preferred positions for the air inlet and air outlet are approximately indicated by the points a and 6, respectively.
Fig. 2 is a longitudinal sectional View of one form of my invention in which the scoop or closure for the air inlet and outlet completely encircles the stream-line body, the
upper half of the drawing shows the scoop in the open or operative condition, while the lower half shows it in the closed or inoperative condition.
Fig. 2* is a sectional view taken along line DD of Fig. 2 in the direction indicated.
Fig. 3 illustrates another embodiment in which a fan is provided within the air passage ways to increase the cooling effect.
Fig. 3 is a sectional view taken along line E E of Fig. 3 in the direction indicated.
Fig. 4 is a side view of a further embodi-. ment of the invention, wherein two laterally disposed scoops or closures are provided for the air inlets and outlets.
Fig. 5 is a horizontal sectional view of the modification illustrated by Fig. 4 and shows the mechanism used to actuate the air scoops. The upper half of the drawing shows the scoop in the closed or inoperative position, while the lower half shows it in the open or operative stage. i
Fig. 6 is an end elevation of the modificatiovn shown in Fig. 5 looking in the direction of travel, the position of the radiator being indicated by dotted lines.
Fig. 7 is a sectional view-taken along line A -A of Fig. 5 looking in the direction indicated.
Fig. 1 shows a car with a streamline body layer .is not pressed against the surface of the car as at the nose by the dynamic pressure, but where the streamlines are widening, the turbulent layer rapidly grows thicker the taperingend, at
and eventually leaves the surface, causing a considerable increase of resistance. In this invention in accordance with these considerations the turbulent layer is' taken away at v a, where it is quite thick, but has not yet left the surface, and is led to the radiator. It is let out at the rear end near .b, where itcannot disturb with its turbulence the streamline flow along the car-body. In the construction of this arrangement, we have two fundamentally different methods. In one the turbulent layer is taken away at the rear of the car by a scoop which is of streamline form and which projects into the turbulent layer and conducts the air to the radiator. In the other method the outer form remains unchanged with respect to streamline, but-in the sur face of the rear of the car-hull are arranged longitudinal channels in which the radiator is situated and through which the cooling air is drawn by a fan.
Fig. 2 shows a longitudinal section through a cooling-arrangement of the first type, in which in the upper part the scoop is shown open and in the lower closed. In front of the rear end of the car is situated the ring shaped radiator cl on a contracted portion of the car-body c. The contracted portion carrying the radiator is covered by the scoop e' for the cooling air which re moves the turbulent air at f and lets itout t g The remaining air stream is not af fected by the scoop because it is moving in stream lines. When it is desired to regulate the cooling effect this may be accomplished by moving axially the scoop 6'. Between the radiator d and the scoop 6' must be arranged a flexible shield 71. of leather or a similar adjusting means.
Another arrangement embodying the same fundamental idea is shown in Figs. 47. In this modification, also, there are arranged on eith-er side of the contraction-of the car body 0 two semicircular radiator blocks 41 (1. But the cooling air is not taken in over the whole circle, but by means of two shutters 2' and z'"for regulation of the air supply, which project from' the side of the car, of which 2' is shown closed and 2" opened. The air enters at and leaves at 76'. A shield Z onthe shutter 71 prevents the air from flowing along the sides of the radiator.
In order to make possible the movement of the shutter 71 without danger of sticking in or obstructing the upper and lower guiding jaws m? and n the arrangement shown in Figs. 5 and 7 is provided. Each shutter 11 is carried at front rear on stiff and parallel, arms of equal length, respectively 0 and p. The arm 0 is fixed to the front spindle g and the arm p to the rear spindle 7". Both. spindles are supported in special bearings s in the car body 0. The
spindles g and r are connected by means of the levers 3 and rods u within the contracted part of the car body. To close the shutters the rods u are moved in the direction of the arrows 'v, and for opening in the, direction of the arrow If the rods u are suitably coupled together both shutters 2' and i can be opened or closed simultaneously.
Obviously this mechanism for operating the shutters may be adapted for use with the modification shown in Fig. 2.
A radiator arrangement of the second type is shown in Fig. 3 in'longitudinal section, in which the cooling air is'drawn into the interior of the car and through the radiator by a fan. The radiator d is situated in suitable channels. For the entrance of the cooling air openings f' are provided in the rear portion of the car, while the cooling air can escape at the extreme rear throughopenings 9'. For drawing the cooling air through the radiator d while the motor is running a fan with blades 3 is provided, mounted on the air-screw shaft :0. The regulation of the cooling effect can be obtained by varying the pitch of the blades Y by means of an arrangement in the hub 2,.
Inside the channel are provided webs h, which hold the ring 2". The webs have a form or covering adapted to the air stream. They also serve as blades for changing the tangential stream into an axial stream or for causing a steady change of stream section. It is also obvious that the fan can be 1n front of the radiator, and that the drive can be carried out in other ways. A remarkable advantage in using a fan is that the cooling effect can be raised to the maximum during the starting period. At this time the motor is working at full power while the air stream velocity and consequently the cooling effect of the other arrangement is very small. F or this reason the radiator must be made much larger. When a fan is used this enlargement is unnecessary. Since under such condition the blades of the fan can be set for full cooling effect, and the radiator need not be made larger.
