Definitions

  • the present invention relates to by pass filter arrangement for a cooler device as defined in the preamble of claim 1.
  • a cooler device as defined in the preamble of claim 1.
  • Such combination of filter and cooler is generally known, e.g. from the non-pre- published patent applications PCT/IB03/04728 and PCT/IB03/06133 both in the name of Applicant.
  • Such combination device is especially know from prior publication of PCT/IB03/03079, also known in the name of Applicant.
  • Such cooler devices for automotive applications come in many variants, mainly to be distinguished between so called oil to water and so called oil to air coolers.
  • coolers are mainly situated in the front side of the vehicle, so that air is forced through the cooler unit by driving of the vehicle.
  • the relevant mechanical device using oil for its functioning air may be forced through the cooler device by the use of a ventilator means.
  • Such combination of cooler device may be either in an in-line arrangement, e.g. as in the pre-published application, or in parallel arrangement, e.g. as in the above first and second mentioned applications.
  • the prior published combination unit relates to a so called oil to water cooler, and has a problem of finding sufficient mounting space at locations under the bonnet, not in the last place due to the combination of size and irregular shape of its packaging.
  • Micro-filters are generally known, e.g. from the PCT-patent publication WO- 0107142 in the name of Applicant, and from SAE paper 2001-01-0867 "Automatic transmission hydraulic system cleanliness - the effects of operating conditions, measurement techniques and high efficiency filters", which document is hereby like said earlier mentioned applications regarded included.
  • the present invention proposes the combination of an oil to air cooler device, integrated with a micro-filter device.
  • space may be found under the bonnet of a car with highest chance of successful application of the combination in most vehicles.
  • space in the engine compartment of a vehicle is not only a highly scarce requirement, but also a non-standardised one.
  • cooler devices favourable use of the comparable, elongated nature of a radiator, and the small amount of space that is often left over in front of the same, i.e. between the grid and the radiator.
  • the micro-filter is combined with said cooler device by means of an elongated housing which is included in said cooler device by a horizontal arrangement of such housing.
  • the filter housing is preferably contained at the lower side of the heat exchanger part of the cooler device, so that width-wise full use is made of available space.
  • a further measure of promoting the combined device according to the invention is to arrange the cooler and device in parallel relationship.
  • the device is equipped with a restriction means, included in an oil leads supplying oil solely to the filter device part.
  • a relatively large capacity oil filter at least a large flow filter may be applied, without endangering the supply of oil to the cooler device.
  • the potential market for such combined device may further be increased, surprisingly by integrating the micro-filter device in any of the vertical main ducts of the cooler device.
  • the diameter, at least the cross sectional surface of such main duct is to be increased compared to customary dimensions without oil filter inside.
  • increased volume mostly at a lateral end of the oil to air cooler limits the possible mounting at certain types of vehicle, or alternatively limits the size of the cooler for reason that it may be made somewhat less wide than without filter, however, it reduces costs of the combination in that less material is to be used, and reduces chances of failure of the combination due to a minimised number of connections of oil leads in the combined device.
  • Such integrated embodiment may of course come either in serial or in parallel as mentioned previously above, and indeed with or without use of said restriction means before or at the entry of the oil filter.
  • oil to be cooled may simply be supplied to the relevant main duct, preferably at the hot oil duct since oil, then being less viscous may then easier pass the micro-filter element.
  • oil passes radial through an at least substantially cylindrical filter element.
  • the entered oil may pass either through the heat exchanging part of the cooler, i.e. the horizontal leads, or through the filter material. In the latter case it exits the main duct by a connection opening to a interior chamber of the filter element, and passing through the duct wall, to be connected to, i,e, to be combined with a discharge leads stemming from the cold vertical oil duct.
  • Figure 1 is a schematic representation of the combined cooler and filter device
  • Figure 2 is a representation according to claim 1 of an embodiment having the filter device included horizontally at the bottom side of the cooler device.
  • Figure 3 is a schematic arrangement of an integrated cooler-filter device according to a further embodiment of the invention.
  • Figure 1 in schematic form shows the basic idea of applicants invention, i.e. the integration of a so called cooler oil to air cooler device 3, generally known per se, with a micro-filter device 2, also generally known per se, into a cooler filter unit 1.
  • the unit 1 shows an oil entry leads 4, which in this example branches into leads 6 and 7 entering the filter device 2 and the cooler device 3 respectively.
  • the entry of the cooler device 3 is via the horizontal main duct 8.
  • a plurality of horizontal, alternatively denoted cooler or sub ducts, not referred to in the drawing, extend towards a second main duct 10 for collecting oil passed through said horizontal ducts for cooling by exchange of heat to air passing between said horizontal ducts.
  • the so- called cold side duct 10 is provided with an oil outlet port 5.
  • the latter is connected to an oil outlet leads 9 of the filter device 2, in casu via said oil collecting main duct 10.
  • the leads 9 may in practice be installed in accordance with insight or preference of the men skilled in the art, e.g. in the case of leads 9, it may also by-pass main duct 10 so as to directly connect to leads 5.
  • FIG. 1 This aspect is also illustrated by the embodiment of figure 2, where the filter device 2 is arranged to the bottom side of the oil to air cooler 3.
  • the outlet leads 9 of the filter directly connects to the outlet leads 5 of the cooler device.
  • Both the embodiments of figure 1 and 2 preferably show a restriction means 6A right in front of the entry of the filter 2.
  • the restriction preferably has the nature of an orifice.
  • the filter and cooler are arranged in parallel arrangement. This feature is especially important since micro filter means, i.e.
  • FIG. 3 shows a third embodiment of the combined unit according to the invention, in which the filter device is fully integrated with the cooler device, i.e. is inserted in one of its main ducts 8A, 10. Preferably in the so called hot side duct 8A. Oil entered in said duct 8A may pass either through the horizontal heat exchange ducts, or radial through a filter element 11.
  • a central chamber 12 thereof is provided with an outlet 13, which passes through a wall part of the main duct 8A towards the discharge leads 5, connecting therewith.
  • a filter device may fully be inserted within the main duct 8A, i.e. entirely with its own housing.
  • the branching of leads 4 into leads 6 and 7 and the provision of the restriction means may either be fully within the main duct 8A, or outside it, in which case two separate pipes enter the duct 8A.
  • the present embodiment is further provided with a releasable lid part 14, for which reason the main duct 8 sticks out above the upper most horizontal duct.

Ce module est caractérisé en ce que le dispositif de refroidissement (3) utilise de l'air pour refroidir l'huile et est conçu pour être situé derrière la grille avant d'un véhicule, sous le capot ou, selon une variante, en combinaison avec une unité de ventilation distincte permettant de faire passer l'air de force à travers ledit dispositif de refroidissement (3). Ce dernier forme un module intégré (1) avec un dispositif filtrant (2). Le dispositif de refroidissement (3) comprend des passages principaux verticaux (8, 8A, 10) entre lesquels s'étendent une pluralité de passages secondaires horizontaux qui sont de préférence dotés de moyens d'élargissement de surface afin de favoriser l'échange chaleur/air.
