(Cl. 257-425) The present invention has for its object to of the cooled liquid; the central header 3, how-_ produce a. radiator for the cooling of aeroplane ever, can be omitted and, in this case, one of engines which offers a minimum resistance » against advance through the air. , A further object is to provide a radiator hav-_ ing a relatively small front surface and a great depth which radiator is easy to manufacture and shows a maximum safety as regards watertight ness. ~ ' Still further objects are to facilitate the possi ble repairs in radiators of great depth, and to avoid the construction of headers .of too great a capacity in order to prevent risks of bursting. The radiators enabling the aforesaid objects to 15 be obtained have the features which will be ap 10 parent from the following description and the accompanying claims, Radiators according to the invention are illus trated by way of example in the accompanying 20 drawings in which: > . ‘ Fig. 1 is a front view of a radiator built. up of the side headers l serves for the inlet of the liq uid to be cooled, whereas the other side header 2 is used as the outlet for the cooled liquid. The radiating network interposed between the headers i, 2 and 3 comprises hollow parallel ‘blades t arranged horizontally and providing be tween the free spaces.5 for the passage of the current of cooling air F. 10x Each of‘ the headers l, 2, 8 is connected at its upper partto a tube 8 which, on the one hand, itself forms a header and on the other hand serves for the assembly of the various radiator elements l1, 63, l3 . . . . 15 . The tubes 8 of two adjacent radiator elements are connected to each other (Fig. 4) by male and female nipples ill, ll ?tting into each other and clamping a sealing joint it’ between them. At each end of the radiator the tubes t of the ?rst 20 and of the last elements are closed by a plug it. The inlet and the outlet of the liquid to be cooled are effected by means of nipples I5, ll, l8 provided on the tubes 8 of one of the elements Fig. 3 is aside elevation of‘said radiator. 25 Fig. 4 is an. enlarged section along 4—6 of‘ and arranged perpendicularly to said tubes. 25 Fig. 1.

This arrangement holds the blades 4 of the various elements I1, I’, l3 in Each radiator element I1, I’, I3... . . has a depth p mutual alignment. 40 " The radiator essentially comprises a plurality of elements I1, l2, l3, juxtaposed to each other 45 which permits ready access to all the members forming said element, for example for cleaning and repairing said element. _ The various radiator elements I‘, I’, l3 V. . are assembled consecutively to each other, to form 60 a radiator with a relatively great depth P which gives said radiator a maximum e?lcacity and e?iciency, and a relatively small front surface. - Each radiator element I1, I”, I3 . . . has two lateral headers |-—2 for-the inletof the liquid to 55 be‘ cooled and a central header 3 for the outlet The locking of the radiator elements thus as 45 sembled with each other is effected by rods or stays‘ Ii, arranged in the axis of the tubes 81, 82, 83,. clamping nuts l5 e?ecting the locking and clamping the sealing joints l2 interposed between the connections In, H. _ , A second emptying header I9 is arranged in the lower part of the radiator. The headerv I9 is composedof the tubes I 9!, I92, I93 correspond ing to the individual radiator elements I1, I’, l3 and communicates by means of theascending 50 2 2,124,787 headers 3 with all the hollow blades 4 of the respective radiator element. The ascending headers 3 open at their upper ends into the head ers, 8 one of which is provided with the outlet nipple it for cooled water. Finally, the locking of the radiator elements ‘can be completed by outer clamping rods 2| ar ranged at the lower angles of the radiator ele ?ttings disposed between the blades of the radiat ing networkof each element, said bracing tubes of each element being adapted to be connected with the bracing tubes of the adjacent elements, and removable means mounted on each element for connecting juxtaposed multiple elements to each other. 2.

The radiator is advantageously completed by multiple elements assembled consecutively to each other in the direction of their own depth, each the ?lters 23 have a great surface and can be of movement, two headers for the inlet of the hot water and the outlet of the cooled water, tubular cylindrical end pieces for said headers disposed 15 parallel to the direction of movement, cross pieces between the headers of the individual elements, nipples arranged in the tubular end pieces of said ?lters 23 lodged in and projecting throughout the element comprising a radiating network having length of the individual tubes 8. Consequently . hollow blades disposed parallel to the direction easily dismounted for cleaning, or repairing by 15 simply disconnecting the elements [1, I’, I3, whereby the interior of the headers 8 becomes accessible and the ?lters can be easilywithdrawn. To sum up, a radiator of great depth is provided which is easy to keep up and to clean as the ‘dis 20 mounting of the elements I1, I", l3 of the radiator can be e?’ected by simply unscrewing the clamp ing nuts from the stays i4, 2_i. The repairing of any of the shallow radiator elements 11, I’, l3 is very simple since all the sol 25 dered points are easily accessible and the indi vidual elements are of small'weight and bulk. headers to establish a communication between the headers of one element and those of the adja 20 cent element, and removable connecting means, arranged on each element and ?xing the indi vidual assembled elements to each other. 3. In a cooling radiator for aeroplane engines, multiple elements assembled consecutively to each 25. other in the direction of their own depth, each Furthermore, if one of the radiator elements is element comprising a radiating network having hollow blades disposed parallel to the direction deteriorated, the interchangeability of the ele of movement, two headers for the inlet of the hot ments permits a speedy replacement of the de water and the outlet of the cooled water, tubular 30 30 teriorated element. This arrangement renders it also possibleto cylindrical end pieces for said headers disposed ‘ add or to eliminate one or a plurality of elements parallel to the. direction of movement, cross pieces between the headers of the individual elements, for tuning up tests of the aeroplane or with re spect to considerable variations of temperature, - nipples arranged in the tubular end pieces of said headers to establish a communication between the 35 35 such as occur between winter and summer. Numerous modi?cations ‘can be made to the headers of one element and those of the adjacent radiator described above-by way of example. As shown for instance in Fig. 8, the radiating net work can consist of tubes 35 (radiators known as “honeycomb”) . In this ?gure, the headers 6 and ‘I4serve respectively for the inlet and outlet of a the liquid to be cooled.
