HANS SIMMON, or wrmf, AUSTRIA APRABA'TUS FOR EXCHANGE OF HEAT Application fled Kay 18, 1926, Serial No. 109,883, and in Austria Kay 19, 1925. p
,The invention consists in improvements in an apparatus for the exchange of heat, the rotatable hollow radiator of which is arranged ina casing and acts as a fan. The
5 radiator is provided with annular ribs, 'arranged coaxially with and perpendicular to the axis of'rotation, presentin thereb an extended heat contacting sur ace wit the surrounding medium and offering little resistance to said medium upon rotation. According to the invention the tubes of the radiator are arranged imparallel rows and'the ribs are so shaped, that they connect several tubes together and are arranged in the same radial row, thus reinforcing the, tubes of the radiator a ainst bending under the influence of centrifugal force. By having partitions arranged alternately at the inside and at the outside of the radiator the medium surrounding the radiator can be forced to flow in counter currentwith the ing drawing in which Fig.1 is a vertical axlal section through the apparatus, and- Fig. is a side elevation, the cover being omitted.
The shaft 1 of the radiator is pivoted by. means of hollow trunnions' 2 and 3 serving as inlet and outlet for the Water, steam or gas. A'pulley 4 is mounted on and drives the shaft. Hollow arms 5 and 6 connect the hollow trunnions withthe hollow rims 7 and Sand which are connected together by means of the tubes 9 of the radiator. The tubes 9 are provided with ribs or fins 10 arranged perpendicular to the axis of the shaft and extending axially in the direction of the rotary motion, so that they cleave the medium flowing through the casing 12 and havin a considerable heat radiating surface. he ribs 10 may be divided into sectors, as shown in the upper part of Fig. part of the same figure and are so arranged,
that they radially connect the tubes together. This arrangement reinforces the tubes against bending under the action of centrifugal force. The radiator is divided 2 or may be annular, as shown in the lower in axial direction in three parts of about equal size by means of an annular partition 11, connected with the shaft and a partition. 13 fixed to and arranged at the inner circumference of the casing -12. The partition 13 extends to the fins but is spaced .a very slight distance therefrom, as indicated at 16, to allow for rotation of the.
radiator. The liquid or steam to be. heated enters through the trunnion 2, .while 'the heating gases enter through the inlet 14.- The heating gases drawn in are first of all forced from the chamber in front of the partition 11 of the radiator in the chamber of the casing 12' located in front of the partition 13, where an increased pressure arises due to the action of centrifugal force. The gases contained in the chamber on the other "side of the partitions 13 are also forced outwardly and leave the casing through the outlet 15. In view of this a vacuum will be built up on the other side of the'partition 11 of the radiator so that in the middle part of the apparatus the gases flow inwardly,
as indicated by the arrows in Fig. 1. The action of the centrifugal force in the two outer com artments overcomes the action of .the centri ugal force in the middle part, so that the desired flow through the apparatus is attained. The two mediums flow in opposed directions, so that a very good efficiency is attained. Instead of the two partitions shown in the example of execution any number of such partitions may be used and it is also possible to omit such parti-' tions.
The apparatus if of course primarily adapted to heat a liquid flowing in inlet 2,
arms 5, tubes 9, arms 6 and outlet 3 by means of hot gases flowing in the casing 12 as 1ndicated by the arrows. It would, however, be possible to reverse the foregoing so that the liquid gives up its heat to heat the gases in the casing.
