To all whom it may concern:
Be itknown that 1, JOHN M. FEDDERS, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the following is a specification.
This invention relates to that type of radiators for use in cooling the water of explosion engines inwhich a plurality of tubes are employed through which the air passes.
and which are arranged side by side so as to form water channels or conduits between the adjacent outer sides of these tubes.
The object of this invention isto provide improved means for increasing the abstraction of the heat of the water from inner sides of these tubes to the atmosphere, which means are capable of being produced at low cost and easily assembled with the tubes and which not only materially increase the efliv Similar characters of reference indicate corresponding parts throughout the several views.
"Although the core of the radiator adapted to receive my improved radiating means may be variously constructed, the same as shown in the drawings comprises a plurality of sheet metal tubes which are arranged si e by side, each of these tubes being preferably of hexagonal form in cross section and having its opposite ends 1, 1, enlarged while its central part 2 intermediate of its ends is reduced in diameter. In the assembled posi tion of these tubes the facets on the enlarged ends of each tube engage with the corresponding facets of adjacent tubes while the intermediate parts of adjacent tubes are separated from each other and form tortu- 011s water conduits or channels 3 between ad-' jacent tubes. The water is circulated through these Water channels or conduits from one end thereof to the other in any suitable manner and the cooling of the same is effected by the How of air through the air tubes in the usual and well known manner.
In order to increase the radiation of heat from the inner sides of the air tubes to the atmosphere each of these tubes is provided with :an internal radiating member which embodies my invention.
In its general construction this improved radiating member comprises a plurality of longitudinal plaits which are arranged in an annular row and engage their outer edges with the inner corners of the bore or the inner side of the respective air tube whereby the radiating member is held against turning in the tube and these parts are held in their proper position circumferentially relatively to each other. In its preferred form this radiating member is divided diametrically and lengthwise into two sections each of which is constructed of a strip of metal which is. corrugated or bent so as to form two whole plalts which are arranged side by side and two half plaits which are ar-' .whole plait are connected with each other at their outer edges but the outer edge of each half plait 5 engages with the outer edge of the adjacent half plait of the companion radiator section so as to form a whole plait therewith, as shown in Fig. 1. The plies of each plait are separated from each other inwardly from their outer edges so that each ply serves to individually carry away heat from the inner side of the air tube and thereby utilize both of its sides for this purpose,
, so as to obtain the maximum radiating eificiency for the amount of metal used. The inner edge of each ply of one plait is connected by a circumferential web 6 with the inner edge of one ply of an adjacent plait and each of these webs is separatedor spaced from the web on the diametrically opposite sides of. the radiating member and is preferably curved concentrically with the axis of the respective air tubes so that the several webs of a radiating member approximately form a tube.
The end portions of the outer edges of the plies of each plait project laterally outward as shown at 7 and these projecting portions engage with the inner sides of the enlarged end portions of the respective air tube while the central part of the outer edge of each ply intermediate of the end portions thereof with the contracted central or interme iate part of the respective tube.. By this means inwardly facing shoulders 9 are formed on the plies of the plaits between the projectmg end portions and the receding central parts thereof which shoulders en age with the outwardly facing shoulder 10 ormed in the bore of the respective air tube between the enlarged end portions and the contracted central part thereof, whereby the radiating member is prevented frommoving len hwise in the tube and is thereby held against displacement.
The projecting and receding portions on the outer edges of the several plaits of the radiating member are preferably formed by extending the end portions of the whole plaits of each section laterally outward the full width of the plies so as to form the ex-' tensions 7 but removing or cuttin away the central part of the outer edges 0 a pair of plies forming a whole plait so that the intermediate parts 8 thereof are disconn ted from each other at theirouter edges an recede relative to the companion end portions of these plies, as best shown in Figs. 2 and 3. T e outer edge of the plies forming one-half o aplait on each radiating section have the end portions 7 of their outer longitudinal edges projecting laterall while their intermediate parts are cut bac to form the reced-- ing central parts 8 thereof so that when each of these half plies is assembled with a companion half ply of another section these two plies together form a whole plait which has substantially the same form as one of the whole plaits in which the two plies are integrally connected at their outer edges.
When placing this .radiating member in an air tube the sections are contracted sufliciently to permit one enlarged end thereof to pass through the contracted central part of the air tube and after these sections have been slipped into the tube far enough to bring their opposite ends into alinement these sections are again permitted to expand so as to engage the enlarged end portions of theradiating member .with the enlarged ends of the tube and the contracted central parts of this member with the central part of the tube. This expansion of the radiating member is possible owing to the resilient or springlike character which this member possesses due to its form.
After the several tubes and the radiating members therein have been thus assembled the opposite ends of these parts are dipped in solder so that the several tubes are connected .with each other at their ends and form a water tight joint therebetween and the opposite ends of the sections of each radiating member are connected with each outer edges of the the outer other and with the companion tube so as to tubes arranged side by side and each tube having enlarged ends which engage with the enlarged ends of adjacent tubes and having its intermediate part reduced whereby the same is spaced from the reduced intermediate parts of adjacent tubes and forms pas sages between the several tubes, and radiating members arranged in each tube comprising a sheet of metal which is corrugated to form a plurality of longitudinal plaits the outer edges of the plies of some plaits being connected with each other and the inner edge of each ply of one plait being connected with the inner edge of a ply of an adjacent plai't, the outer edges of-the plies of each plait having their end portions projecting laterally into engagement :with the enlarged ends of the respective tube and the intermediate outer edge portions of the plies of each plait receding inwardly relative to the comhaving enlarged ends which engage .with theenlarged ends of adjacent tubes and having its intermediate part reduced whereby the same is spaced from. the reduced intermedi ate parts of adjacent tubes and forms pas sages between the'several tubes, and. radiating members arranged in each tube comprising a sheet of metal which is corrugated to form a plurality of longitudinal plaits the plies of some plaitsbeing connected with each other and the inner edge of each ply of one plait being connected with the inner edge of a ply of an adjacent plait, edges of the plies of some plaits having their end portions connected and projecting laterally into engagement with the enlarged ends of the respective tube while the intermediate parts of the outer edge ortions of said plaits are disconnected om each other and recede relatively to the com- In its completed form this radiator not 3. A radiator comprising a' plurality of I tubes arranged side by side and each tube having enlarged ends which engage with the enlarged ends of adjacent tubes and having its intermediate part reduced whereby the same is spaced from the reduced intermediate parts of adjacent tubes and forms assages between the several tubes, and ra iatmg members arranged in each tube comprising a sheet of metal which is corrugated to form a plurality of longitudinal plaits the outer edges of the plies of some plaits being connected with each other. and the inner edge of each ply of one plait being connected with the inner edge of a ply of an adjacent plait, said radiating member being divided lengthwise into a plurality of sections each of which contains a whole plait which has its two plies connected at their outer edges and 10 their inner edges disconnected and two half plaits each of which has its inner edge connected with a ply of an adjacent plait While its outer edge engages with a ply forming a half plait of another section.
