Definitions
- the invention relates to a cooling radiator of a motor vehicle engine.
- the invention relates more particularly to a radiator of cooling of the type comprising a bundle of tubes in heat exchange with air and in which the engine coolant.
- a radiator of cooling of the type comprising a bundle of tubes in heat exchange with air and in which the engine coolant.
- Such a radiator has an orifice inlet and outlet for the heat transfer liquid.
- the inlet and outlet ports must be separated from one of the other.
- the two holes must be arranged so diametrically opposite with respect to the central part of the radiator. That is, the inlet is located on one side from the top of the radiator, while the outlet is located at the bottom and on the other side of the radiator. End caps mounted respectively on the orifices of entry and exit ensure the arrival and the evacuation of the cooling liquid.
- Another problem posed by the radiators described above is their large size in the direction vertical.
- An object of the present invention is to provide a vehicle engine cooling radiator automobile, overcoming all or part of the disadvantages of art previously noted above.
- the radiator of motor vehicle engine cooling includes an inlet for coolant to a bundle of tubes in heat exchange with air, the liquid performing at least two passages in opposite directions in the beam, and an outlet for the liquid having circulated in the bundle, the inlet and outlet ports being located near a same plane which is substantially parallel to the direction of circulation of the liquid in the beam and perpendicular to the plane of this beam, the two orifices being located, at least in part, in the longitudinal extension of the same portion beam in which the liquid flows in one direction determined.
- the radiator 1 has a central part consisting of a bundle 7 of tubes in which the engine coolant of a vehicle.
- the tubes are in heat exchange with the air outside so as to constitute a heat exchanger of the liquid / air type.
- the tubes which are not shown in figures for the sake of simplification, are oriented vertically.
- the upper end of the bundle 7 of tubes is capped of an inlet water box 6 comprising an inlet port 2 for coolant.
- the lower end of the the beam is closed by a water box 8 of outlet provided with an outlet orifice 4 for the liquid having circulated in bundle 7.
- the inlet 2 and outlet 4 ports can be delimited respectively by two end pieces 12, 14 of connection. As shown in Figures 2 and 3, both end pieces 12, 14 may be substantially perpendicular to the plan of the radiator, so as to project on the same side of the radiator 1.
- the inlet 2 and outlet 4 ports are located at proximity to the same vertical plane substantially perpendicular to the plane formed by the beam 7, preferably in the extension (on one side or the other) of the same portion of the beam in which the fluid circulates in a determined meaning.
- the 6 inlet water box has a guide partition 5 located under the orifice 2 entry.
- the guide partition 5 is slightly inclined by relation to a horizontal plane and perpendicular to the plane of the radiator 1. More precisely, the partition 5 is inclined towards the low away from the inlet 2, to offset the liquid entering the bundle 7 relative to this port 2.
- the liquid makes a first pass P1 from top to bottom in a first portion of bundle 7 of tubes.
- the liquid is then guided by the outlet box 8 of so that it changes its meaning and makes a second pass P2 from bottom to top.
- the partition 5 and the box 6 of water inlet then guide the liquid to ensure a change of direction towards a third passage P3 from top to bottom.
- the liquid then comes out through the orifice 4. That is to say that the radiator 1 is of the type with circulation known as "in Z".
- FIG 4 illustrates an example of installation of the radiator 1 described above in the engine compartment of a vehicle automobile.
- the radiator 1 is located at the front of an engine 3, and under an element 11 of front transverse structure.
- Engine 3 and an air intake device 17 are located between two elements 15, 16 of longitudinal structure.
- the inlet tips 12 and outlet 14 are located substantially in the same vertical plane and perpendicular to the plane of radiator 1, at a location with enough space not to interfere with the motor 3.
- the guide wall 5 may have a substantially shaped cross section of inverted U. Partition 5 is maintained in its part upper by shoulders 9 preventing its displacement to the top.
- the lower ends of the two parallel branches of the U formed by the partition 5 are blocked between the end bottom of the water box 6 and the upper end of the bundle 7.
- the upper end of bundle 7 has, for example, a flange 10 which is crimped on the base of the box water 6.
- the guide partition 5 can be fixed in the water box 6 by any other suitable means, for example by welding.
- Figure 6 illustrates another alternative embodiment in which the guide wall 5 is inclined in two separate directions. That is to say that the partition 5 is inclined not only in a first direction D1 substantially parallel to the beam 7 plane (see Figure 1), but also in a second direction D2 substantially perpendicular in the plane of the beam 7. According to the invention, this form of the partition 5 can be considered independently of the relative positioning of the inlet 2 and outlet 4 ports.
- the partition 5 is inclined towards bottom in the direction in which the end caps 12 are protrusion from the beam plane 7.
- the edge lower of partition 5 substantially coincides with the end upper beam 7.
- the housing 6 for water outlet has a height H2 reduced compared to the height H1 of the modes of realization of Figures 3 and 5.
- the inclined partition 5 allows to save in the thickness of the box 6 and / or the inlet nozzle 12 a reduced space 18 to allow the liquid to change direction between two passages in the beam 7.
- the partition 5 inclined in both directions can also have a section transverse U-shaped.
- the partition 5 can be fixed analogously to that described above with reference in Figure 5 (elements identical to those described above are designated by the same reference numerals).
- FIG. 8 illustrates a radiator 1 according to another variant for carrying out the invention.
- the radiator 1 illustrated in the figure 8 is of the "U" type. That is to say that the liquid performs only two passages P1, P2 in opposite directions.
- the upper end of the bundle 7 is closed by a box 6 of inlet water and box 8 of outlet water comprising respectively the inlet 2 and outlet ports 4.
- the lower end of the bundle 7 is closed as regards it by a housing 17 intermediate.
- the radiator 1 comprises a guide wall 5 which separates the input boxes 6 and outlet 8.
- the partition 5 is inclined downwards and its lower end substantially coincides with the middle of the upper edge of the bundle 7.
- the two orifices 2, 4 can thus be close to each other while ensuring two passages P1, P2 in the bundle 7 for the liquid.
- the radiator according to the invention while being simple and inexpensive in structure, can better adapt to the small spaces available when its location.
