RADIATOR FOR INTERNAL-CQMBU'STION EEI'GiIlN'IS.l
Application led January' 14, 1925. Serial No. 2,455.
`To all 'whom it may concern.' l Be it known that I, FERDINAND PORSCHE,
a citizen'of the Republic of Czechoslovakia, residing at Stuttgart-Unterturkheim, Wurt- 5 temberg, Germany, havev invented certain new and useful Improvements in a Radiator for Internal-Combustion Engines, ofwhich the following is a specification. v y
This invention relates to coolers or ra- 10 diators of the kind in which the tempera-" ture is regulated vwith the aid of a thermostat or thermostats controlling the low of the hotcooling water, or of the water to be cooled through the cooler or radiator, andthe invention consists in so devising the .side parts or lateral members" v of the cooler orradiator, or of its casing, that they can serve'as conduits for saitl water,-
either directly' or indirectly, that is to say,-
said side parts or; lateral members may serve themselves as water-conducting means, or separate pipes may be provided' therein.
Another feature of the invention.'consists in arranging the thermostat or thermostats in the said passages or pipes, as is more fully described'hereinafter with the aid of an example, illustrated in the accom acrying drawing which shows diagrammatical..y
- a vertical cross-section through .a cooler or 80,' radiatordevised according to this invention. The hot water arriving fromtheinternal combustion engine, or from the motor, ilows into the cooleror radiator throughthe pipe 'b which terminates Withinv the top thereof. c denotes the coolingl pipes proper which are surrounded by a casing or frame.- Now,
in contradi'stinction to known constructions` the side-parts Vor lateral members 'd .and e of this casing or frame are hollow and for'u 40 channels or passages or, more' precisely,'b\
passes 'for the coolin -water which, thus,-
- ilows throughjthe coo ing-pipes proper, as well as these ,latter which are opened 'or closed more or less by thermostatic valves f and g arranged therein, as shown. f When the temperaturefof the water becomes higher than desired, the passa es or,
channels d land eg are correspon ingly .j throttled bythe thermo'st'atic valves-.and afp ,50 correspondingly larger amount'ris, 'conse-' water sinks' below thedegree desired, the
-arate illustration and a separate detailed directl control the flow of the water there,-
therefore, cooled correspondin ly lower., If,
however, the temeprature o the cooling thermostats 'operate in the reverse way,vthe
throttling being now correspondingly diminished, so that more water is iiowing through the channels d e and less through the pipes c.
The water flows from 'the top-chamber of the cooler into the pipes c and the channels d'e, and the three currents re-unite then in the lower chamber from which the cooled waterilows off through the pipe h.
The channels d and e are, 1n the example shown, provided in the side-parts lof 4the .cooler-.which are hollow for that purpose,
but instead of these side-parts themselves separate tubes ma be employed whichl are arranged within t e same, the thermo'static-A valves being, then, of course, arranged in said tubes, as will be clear without 'a. sepdescription. I5
