Definitions
- the present invention concerns a radiator for an internal combustion engine, and more particularly for an internal combustion engine of a heavy vehicle, including upper and lower header boxes, each having first and second ends, and side members, each having first and second ends adapted to be connected to a respective one of said first and second ends of said header boxes to form therewith a relatively rigid frame, and, enclosed within said frame, a cooling block including a plurality of tubes communicating with their respective ends with said upper and lower header boxes for directing a flow of cooling fluid therebetween, a first of said header boxes having first engagement means at each of said first and second ends thereof, each of said side members having second engagement means at said first end thereof for releasable engagement with said first engagement means of said first header box.
- a radiator of this general kind is disclosed in EP-A1-0 346 602.
- a first header box of this known radiator is connected to a first end of a side member by hinge-like engagement means and snap-action engagement means
- the second header box is connected to the second end of the side member by a snap-action locking device.
- this radiator utilizes a separate wedge introduced between the side member at its second end and the header box after locking of the locking device.
- the header boxes are provided with several protrusions and the side members with corresponding recesses which inter-engage in the assembled position of the radiator.
- radiators are exposed to thermal stresses due to widely varying internal temperatures during operation of the engine, e.g., from far below the freezing point up to the boiling point of water, as well as temperature differentials between the radiator and the environment. Radiators are also exposed to stresses caused by vibrations due to engine running and vehicle driving.
- Temperature variations cause longitudinal expansion and contraction of the cooling fluid tubes leading to stresses in the connections between the header boxes and the lateral members.
- US-A-4 540 044 proposes a solution of this problem by providing oblong holes for pins connecting the header boxes and the lateral members, said holes having their maximum transverse dimension extending in the longitudinal direction of the tubes, thereby to accomodate relative movements between the header boxes and the lateral members.
- FR-A-2 538 030 proposes another solution of the same problem by providing the tube plates of the header boxes with deformable portions such that said portions, where the tubes are fastened to the tube plates, may move without transferring movement to the header boxes, and, thus, without affecting the distance between the header boxes defined by the lateral members rigidly connected thereto.
- resilient means are provided between the lateral members and outer mounting members extending in the longitudinal direction of the lateral members. Threaded bars extend between the outer mounting members to exert a pulling force therebetween, thereby to keep the radiator package together.
- the outer mounting members are secured to the header boxes by means of screws extending through holes provided in the mounting members and the header boxes.
- EP-B-0 020 190 proposes a solution of the vibrational stress problem by completely enclosing the assembled radiator in a multi-piece frame or cradle.
- Resilient means are interposed in the corners between the radiator and the frame such that the resilient means are tensioned and keep the radiator under permanent compression.
- the complete radiator package is kept together by means of bolts and spot welds.
- US-A-4 738 308 discloses an arrangement allowing compensation of differential dilatations which can occur between the cooling fluid tubes and the lateral members, or, flanges, due to different temperatures.
- the lateral members are generally C-shaped sections having a bottom, lateral sides and inwardly bent wings, the latter being engaged in notches provided in fins in which the tubes are engaged. Assembly of the header boxes and the side members of this prior art radiator includes plastic deformation, i.e., bending, of lugs provided on the lateral members.
- All the four prior art structures last referred to above employ some kind of more or less permanent fastening or securing means to attach the side members to the header boxes, such as pins, threaded bars, welds and bent lugs, all increasing the manufacturing costs due to material and labour required.
- the problem to be solved by the present invention is to provide a radiator of the kind initially stated, and particularly a connection between a side member and the header boxes of such a radiator, which - as taught by EP-A1-0 346 602 - widely avoids the use of fastening means, such as bolts or pins, or post-assembly treatment, such as welding or soldering, for obtaining a secure and releasable connection still allowing expansion and contraction of the radiator package due to heat variations.
- fastening means such as bolts or pins, or post-assembly treatment, such as welding or soldering
- the use of fastening means shall be completely avoided.
- there shall be no need of separate mounting means, such as the wedge according to EP-A1-0 346 602 and the solution shall provide compensation for manufacturing tolerances and reduce vibration transmission between the side member and the header box.
- a radiator as initially stated is characterized in that said first engagement means and said second engagement means are adapted, when mutually engaged, to allow displacement of said first ends of said side members substantially perpendicularly to the longitudinal direction of said first header box and to prevent displacement in other directions, that a second of said header boxes has first guide means at each of its first and second ends, that each of said side members has second guide means at its second end, said first and second guide means being adapted, when mutually releasably engaged, to allow displacement of said second ends of said side members substantially in the longitudinal direction of said second header box and to prevent displacement in other directions, and that resilient means is interposed between said coolimg block and said side members at said first end thereof, said resilient means being compressed between said first ends of said side members and said cooler block upon displacement of said second ends of said side members towards each other along said first guide means.

- a cooling block 5 (not shown in detail), conventionally having a plurality of vertically extending tubes, the upper and lower ends of which being fluid tightly engaged in a respective one of upper and lower tube plates 6 and 7.
- Tube plates 6 and 7 have lugs 6′, 7′, respectively, folded around circumferential rims 1′, 2′ of the header boxes, thereby closing the respective open U-section of the upper and lower header boxes 1 and 2 so as to form in each header box a fluid chamber.

Description
- The present invention concerns a radiator for an internal combustion engine, and more particularly for an internal combustion engine of a heavy vehicle, including upper and lower header boxes, each having first and second ends, and side members, each having first and second ends adapted to be connected to a respective one of said first and second ends of said header boxes to form therewith a relatively rigid frame, and, enclosed within said frame, a cooling block including a plurality of tubes communicating with their respective ends with said upper and lower header boxes for directing a flow of cooling fluid therebetween, a first of said header boxes having first engagement means at each of said first and second ends thereof, each of said side members having second engagement means at said first end thereof for releasable engagement with said first engagement means of said first header box.
- A radiator of this general kind is disclosed in EP-A1-0 346 602. In order to provide a stable connection between the side members and the header boxes of this known radiator, without the need of time-consuming and expensive mounting work, a first header box of this known radiator is connected to a first end of a side member by hinge-like engagement means and snap-action engagement means, and the second header box is connected to the second end of the side member by a snap-action locking device. Still, this radiator utilizes a separate wedge introduced between the side member at its second end and the header box after locking of the locking device. Further, the header boxes are provided with several protrusions and the side members with corresponding recesses which inter-engage in the assembled position of the radiator.
- As is well known in the art of internal combustion engine radiators such radiators are exposed to thermal stresses due to widely varying internal temperatures during operation of the engine, e.g., from far below the freezing point up to the boiling point of water, as well as temperature differentials between the radiator and the environment. Radiators are also exposed to stresses caused by vibrations due to engine running and vehicle driving.
- Temperature variations cause longitudinal expansion and contraction of the cooling fluid tubes leading to stresses in the connections between the header boxes and the lateral members.
- Different solutions of this thermal stress problem are disclosed in US-A-4 540 044, US-A-4 738 308, EP-B-0 020 190 and FR-A-2 538 030.
- US-A-4 540 044 proposes a solution of this problem by providing oblong holes for pins connecting the header boxes and the lateral members, said holes having their maximum transverse dimension extending in the longitudinal direction of the tubes, thereby to accomodate relative movements between the header boxes and the lateral members.
- FR-A-2 538 030 proposes another solution of the same problem by providing the tube plates of the header boxes with deformable portions such that said portions, where the tubes are fastened to the tube plates, may move without transferring movement to the header boxes, and, thus, without affecting the distance between the header boxes defined by the lateral members rigidly connected thereto. Also, resilient means are provided between the lateral members and outer mounting members extending in the longitudinal direction of the lateral members. Threaded bars extend between the outer mounting members to exert a pulling force therebetween, thereby to keep the radiator package together. Also, the outer mounting members are secured to the header boxes by means of screws extending through holes provided in the mounting members and the header boxes.
- EP-B-0 020 190 proposes a solution of the vibrational stress problem by completely enclosing the assembled radiator in a multi-piece frame or cradle. Resilient means are interposed in the corners between the radiator and the frame such that the resilient means are tensioned and keep the radiator under permanent compression. The complete radiator package is kept together by means of bolts and spot welds.
- US-A-4 738 308 discloses an arrangement allowing compensation of differential dilatations which can occur between the cooling fluid tubes and the lateral members, or, flanges, due to different temperatures. The lateral members are generally C-shaped sections having a bottom, lateral sides and inwardly bent wings, the latter being engaged in notches provided in fins in which the tubes are engaged. Assembly of the header boxes and the side members of this prior art radiator includes plastic deformation, i.e., bending, of lugs provided on the lateral members.
- All the four prior art structures last referred to above employ some kind of more or less permanent fastening or securing means to attach the side members to the header boxes, such as pins, threaded bars, welds and bent lugs, all increasing the manufacturing costs due to material and labour required.
- The problem to be solved by the present invention is to provide a radiator of the kind initially stated, and particularly a connection between a side member and the header boxes of such a radiator, which - as taught by EP-A1-0 346 602 - widely avoids the use of fastening means, such as bolts or pins, or post-assembly treatment, such as welding or soldering, for obtaining a secure and releasable connection still allowing expansion and contraction of the radiator package due to heat variations. Preferably, the use of fastening means shall be completely avoided. In solving this problem, there shall be no need of separate mounting means, such as the wedge according to EP-A1-0 346 602, and the solution shall provide compensation for manufacturing tolerances and reduce vibration transmission between the side member and the header box.
- According to the present invention, a radiator as initially stated is characterized in that said first engagement means and said second engagement means are adapted, when mutually engaged, to allow displacement of said first ends of said side members substantially perpendicularly to the longitudinal direction of said first header box and to prevent displacement in other directions, that a second of said header boxes has first guide means at each of its first and second ends, that each of said side members has second guide means at its second end, said first and second guide means being adapted, when mutually releasably engaged, to allow displacement of said second ends of said side members substantially in the longitudinal direction of said second header box and to prevent displacement in other directions, and that resilient means is interposed between said coolimg block and said side members at said first end thereof, said resilient means being compressed between said first ends of said side members and said cooler block upon displacement of said second ends of said side members towards each other along said first guide means.

- Fig. 12 a, b and c
- are front views of the left hand side of a radiator according to the present invention showing three steps of the assembly of a side member and the header boxes.
- The assembled outer structure of the radiator shown in the drawings includes two equally shaped header boxes, an
upper header box 1 having in its mounted position an inverted U-shaped section (Fig. 4, upper part) and alower header box 2 having a U-shaped section (Fig. 4, lower part), and two equally shaped side members, afirst side member 3 and asecond side member 4, the header boxes and the side members forming in their mounted position according to Fig. 1 a relatively rigid frame. Enclosed in this frame is a cooling block 5 (not shown in detail), conventionally having a plurality of vertically extending tubes, the upper and lower ends of which being fluid tightly engaged in a respective one of upper andlower tube plates 6 and 7.Tube plates 6 and 7 have lugs 6′, 7′, respectively, folded aroundcircumferential rims 1′, 2′ of the header boxes, thereby closing the respective open U-section of the upper andlower header boxes header box inlet 8, communicating with an internal combustion engine not shown, is distributed within the interior of the upper header box and directed downwards through the plurality of tubes to be collected in the lower header box and returned to the engine through anoutlet 9. - As mentioned, the header boxes are equally shaped, preferably being molded from a thermoplastic synthetic material in one and the same mould, and, thus, in their mounted positions, one header box is turned upside down and rotated 180° relative to the other header box. Consequently, the
inlet 8 of the upper header box and theoutlet 9 of the lower header box are corresponding portions of the respective header box located near one end thereof. Near the other end of the respective header box is formed a threaded hole in which is fitted anipple 10 in the upper header box for ventilating the radiator system, and, in the lower header box aplug 11. - Since
side members header boxes side member 3 and the left hand end portions of the header boxes according to Fig. 1 will be described more in detail. -
Side member 3 has a generally U-shaped section comprising aweb portion 12 and twoflange portions side member 3 theflange portions web portion 12 and inwardly towards the vertical centre of the radiator to formwings vertical lugs respective wing 15, 16 (Fig. 5). At the lower end ofside member 3 theflange portions wings horizontal lugs - The U-shaped sections of the header boxes have substantially parallel
outer side walls circumferential rims 1′,2′, and, respectively, a flat outer top andbottom wall 25 having lengthwise and crosswise extendingintegral reinforcement ribs inclined walls 28 the inclination of which substantially corresponds to the inclination of theupper wings portions 29 of the side walls and vertically and horizontally extendingribs slots vertical slots 32 are dimensioned to receive thevertical lugs horizontal slots 33 to receive thehorizontal lugs - When mounting a
side member 3 to the upper and lower header boxes thelugs lower header box 2 in order to keep thehorizontal lugs vertical slots 32 must be made wider than the thickness of thevertical lugs side member 3. When upper end ofside member 3 has been lowered to the position shown in Fig. 12b, lower end thereof is moved to the right (Fig. 12c), the horizontal lugs 21, 22 being guided along thehorizontal slots 33. - According to the present invention there is provided at least one resilient means between each side member and the
cooling block 5. In the embodiment of Figs. 1 - 7, aresilient element 34 is inserted between the upper portion of eachside member upper header box 1. The position of suchresilient element 34 is shown in Fig. 3. Preferably,element 34 is U-shaped in a vertical cross-section (Fig, 12a) so as to grip around an end portion ofheader box 1, or, header plate 6 and its lugs 6′ folded around thecircumferential rim 1′ of the header box, thereby to be kept in place during the assembly. It is preferred, also, thatelement 34 has a U-shaped horizontal cross-section (Fig. 5), thereby to grip around the corners of the rim of the header box. - The dimension of the
resilient element 34 is such that it is compressed between the side member and the header box during assembly, starting approximately in the position of Fig. 12b and increasing towards full compression in the position of Fig. 12c. Both ends ofside member 3, thus, will be urged outwardly byelement 34, movement of the upper end of side member, however, being positively prevented by the engagement of thevertical lugs vertical slots 32 of the upper header box. In the embodiment of Figs. 1 - 7 the lower end ofside member 3 is blocked against movement due to expansion ofresilient element 34 by means of aconventional bolt 35 inserted in corresponding holes throughside member 3 andlower header box 2,such hole 36 through lower header box being shown in Fig. 7. - The second embodiment of the present invention according to Figs. 8 - 12 differs from the first embodiment according to Figs. 1 - 7 only regarding retainment of the lower ends of the side members to the ends of the
lower header box 2. According to the second embodiment, thus, the lower ends of side members and the ends of the lower header box are provided with interengaging means to establish a snap-action locking connection between the side member and the header box. - More precisely, the
side walls abuttment portion 39 perpendicular thereto and also perpendicular to the respective side wall of the header box. Thelower wings abuttment portion 39 and a portion of thecam surface portion 38. When, during assembly of the radiator, the lower end ofside member 3 is to be connected to the left end of header box 2 (Fig, 12b), thewings cam surface portion 38 until the T-shapedopening 40 snaps over theabuttment portion 39 and the portion of the cam surface portion closest thereto (Fig. 12c). In this position the lower end ofside member 3 is positively kept in its intended position by inter-engagement between theabuttment portion 39 and the corresponding portion of T-shapedopening 40. - In order to make this second embodiment connection between the lower end of the side member and the header box more stable, it is preferred to interpose a
resilient element 34′ corresponding to theelement 34 therebetween also at this end as is shown particularly in Fig. 12a. - To prevent the
upper wings lugs resilient element 34 compressed between theweb portion 12 of the side member and the header box portions of the vertically extendingribs 30 are provided with L-shaped outward extensions 41 (Figs. 3, 5, 7) havinglegs 42 directed towards the side member so as to extend over portions of thewings
