Abstract

Description
- The invention relates to a device for regulating the circulation of a coolant liquid for a heat exchanger, in particular for a motor vehicle engine charge air cooler and to the obtained heat exchanger.
- In this field, exchangers, so-called charge air coolers are known, allowing heat exchange between the air charge, intended to feed the engine of the vehicle, and a coolant liquid. They comprise a heat exchange bundle defining alternating circulation channels for the air charge and for the coolant liquid. Such exchangers have the advantage of being able to be freely positioned under the hood, notably in proximity to the engine of the vehicle, unlike the charge air exchangers cooled by means of an outdoor air bundle which require being positioned in the front face of the vehicle or at the very least in proximity to an air intake.
- In order to ensure thermal regulation of the air charge, today it is known how to have the air charge pass either through the exchanger, or through a by-pass circuit. In this way it is possible to modify the temperature of the air sent to the engine depending on the air fraction crossing the exchanger and on the air fraction passing through the by-pass route.
- Because of the sections required for the air flow, these solutions are, however, relatively cumbersome.
- The object of the invention is to find a remedy to this drawback and to propose for this purpose a device for regulating the circulation of a coolant liquid for a heat exchanger, in particular a motor vehicle engine charge air cooler, said device including a body configured so as to be attached to said exchanger, said body defining at least one chamber for circulation of the liquid, said device further comprising a means for distributing said liquid in the chamber giving the possibility of modulating the temperature and/or the flow rate of the coolant liquid in the exchanger.
- By carrying out regulation by means of a coolant liquid circuit, the device of the invention thus gives the possibility, in a reduced size, of ensuring thermal regulation of the air charge of the exchanger. The integration of said device to the exchanger further allows a ready-to-mount module to be available.
- Advantageously, said body comprises at least one inlet for said liquid in the chamber, first and second outlets of said liquid of the chamber, said first outlet being configured so as to be connected to the inlet of the exchanger, said device being configured for allowing the coolant liquid to by-pass at least partly the exchanger through said second outlet, said distribution means being configured so as to carry out a distribution of the coolant liquid between said first and second outlets of the chamber.
- The device thus gives the possibility of distributing in said chamber, the flow of the liquid in circulation at the inlet between said first and second outlets of the chamber and thereby regulate the flow rate of the coolant liquid circulating in the exchanger, and thus, adjust this circulation to the needs for cooling the air charger in order to either completely cross the exchanger for cooling it, or partly passing through the exchanger for partly cooling it, or by-passing the exchanger so as not to cool it. It further gives the possibility of operating the pump for circulating the liquid at its rated speed and therefore with minimum fatigue.

-
- said regulation device includes a bypass conduit connected to said second outlet and configured so as to be connected to the outlet of the exchanger,
- said regulation device includes a pump for circulating the liquid, and by doing this, gives the possibility of controlling the circulation of the coolant liquid in the exchanger as close as possible to the latter, in a fine adjustment,

Said device further comprises ameans 12 for distributing said liquid in the chamber giving the possibility of modulating the temperature and/or the flow rate of the coolant liquid in the exchanger. In this way it is possible to ensure thermal regulation of the air charge with the coolant liquid, and this by means of a device integrated to the exchanger. - Said
body 17 includes here aninlet 21 for said liquid in thechamber 19, afirst outlet 23 and asecond outlet 25 of said liquid from the chamber. Saidfirst outlet 23 is connected to theinlet 13 of the exchanger, while the device is configured for allowing the coolant liquid to by-pass at least partly the exchanger through saidsecond outlet 25, for example through abypass conduit 27 of the device connected to thesecond outlet 25 and to theoutlet 15 of the exchanger.

pump 9 for circulation of the liquid, either positioned at a distance or not from thedevice 11, may operate under its rated conditions, while the device gives the possibility of regulating the flow rate of the coolant liquid L circulating in theexchanger 3, as close as possible to the latter in a fine adjustment, in order to adjust this circulation, according to the direction of the arrows, to the needs for cooling the air charge A so as to either completely pass through the exchanger for cooling it, or partly crossing the exchanger for partly cooling it, or by-passing the exchanger so as not to cool it. This regulation is advantageously controlled in correspondence with the need for cooling the air charge of the engine A. - Said distribution means in particular comprises a
valve 12, here a three-way valve, including thechamber 19 and said means 29 for distributing said liquid, positioned in thechamber 19. This distribution means 29 is for example, a gate actuated in a rotary way in said valve chamber in order to distribute the coolant liquid L among said first and second outlets of thechamber - Said device may comprise an actuator of said distribution means, for example provided in a housing of said body, parallel to said
chamber 19. The control of the actuator is notably electric and/or pneumatic. It may be controlled by said computing device of the vehicle, in connection with the needs of the engine. - Said
valve 12 is here of the rotary type. It is actuated via its distribution means 29 by the actuator which may also be rotary, notably via pinions forming a kinematic connection, which gives the valve a compact structure, easy to integrate to the regulation device. - The
regulation device 11, i.e. comprising here thevalve 12 and theconduit 27, is advantageously in one piece, for example from plastic material molding, as this appears inFIG. 5 . - As already mentioned, said
exchanger 3 includes here aninlet 13 and anoutlet 15 of said coolant liquid on a same side of saidbundle 7, saiddevice 11 being configured so as to be connected to theexchanger 3 at said same side. More specifically, the exchanger includes, as aforementioned, aheat exchanger bundle 7 provided withblades 30 for circulation of said liquid and at least onecolumn 31 for inflow of said liquid in communication with said blades, as this is seen inFIG. 6 . Thevalve 12 may be positioned, at least through thechamber 19, in said inflow column for the liquid 31 or adjacent to the latter. - As said exchanger is more specifically in the example of the type with side inlets, it comprises two
boxes 33 of liquid on a same side of the bundle, these boxes of liquid being housed for said onecolumn 31 for inflow of the liquid in the bundle, and for the other acolumn 35 for outflow of the liquid of the bundle. Said valve and/or device is then configured so as to be positioned between both of saidcolumns boxes 33 of liquid, or even integrated to saidboxes 33. - More particularly, the exchanger may comprise a lid configured so as to be assembled to the
bundle 7 at said same side, said lid defining said boxes for inflow and outflow ofliquid 33 and said body, notably saidchamber 19 for the distribution means and/or said housing for the actuator. - The lid is connected to the exchanger, for example to the
bundle 7 of the exchanger like here, to its perimeter, for example by welding, braising, crimping or other technique, or to a wall of a case or of a lid of the exchanger (not shown). Optionally, ahood 36 may be mounted, screwed, onto saidbody 17 as illustrated, which allows access to the distribution means 29. - As indicated above, the conduit 27 (
FIG. 6 ) allows the coolant liquid to by-pass at least partly theexchanger 3 so as to be brought from thesecond outlet 25 to theoutlet 15 of the exchanger. - Said
conduit 27 is positioned at the upper portion of thechamber 19 and is connected to anoutlet conduit 37 of the exchanger. Theconduit 27 may further be connected to saidbox 33 for outflow of the liquid. - It should be noted that said valve is preferably of the type with positive safety or “failsafe”. In other words, it is advantageously configured for letting through the coolant liquid in the exchanger in the case of an operating fault.
- According to the alternative embodiment of
FIG. 3 , the device includes apump 9 for circulating the coolant liquid(s), which is shown here integrated to saidregulation device 11, for example mounted and secured to the regulation device. In this case, the regulation device allows modulation of the flow rate of the coolant liquid in the exchanger, with a reduced response time relatively to the drive of the pump. - According to the alternative embodiment of the
regulation device 11 ofFIG. 8 , thechamber 19 includes twoinlets inlet 21 of a liquid L from a low temperature circuit and aninlet 21′ of a liquid from a high temperature circuit L′. The distribution means 12 then comprises a distribution means 29′ of theinlet chamber 19, this in addition to said distribution means of the liquid 29 in the chamber between the first andsecond outlet sensor 39 for the temperature of the liquid in the chamber, so as to produce in the chamber a mixing of said liquids L, L′ at a determined temperature, which allows additional regulation of the exchanger according to the temperature of the coolant liquid. - According to the alternative embodiment illustrated in
FIGS. 4 and 7 , theregulation device 11 is dual and includes twochambers 19, as described earlier, each containing a coolant liquid at a determined temperature from the mixing of both liquids L and L′, respectively from a low temperature circuit and from a high temperature circuit. The exchanger may be with twostages 40, each of the chambers being configured for feeding one of thestages 40 of the exchanger with one of the coolant liquids at a determined temperature. - The invention thus provides a possibility for regulating accurately and rapidly a heat exchanger, in particular a motor vehicle engine charge air cooler, in a fine adjustment of the flow rate and optionally of the temperature of the coolant liquid circulating in the exchanger.
