Description
Cooling module for an internal combustion engine
FIELD OF THE INVENTION The present invention generally relates to the field of automotive engine cooling and air conditioning systems, and more particularly to a cooling module.
BACKGROUND OF THE INVENTION Internal combustion engines used for automotive applications utilize a cooling system for assuring proper cooling of the engine during its operation. The cooling system includes a radiator and a fan assembly which provides an atmospheric heat dump for a circulating liquid coolant. Additionally, most motor vehicles include, either as an option or as standard equipment, passenger compartment air conditioning. Air conditioning also must have an atmospheric heat dump to operate properly, in this case via a condenser through which heated refrigerant circulates.
Conventionally, the condenser and radiator are rectangularly shaped of more or less comparable dimensions and placed in a closely-spaced, stacked relationship at a vehicle location whereat air flow therethrough is facilitated. In this regard, a fan unit is placed adjacent the condenser/radiator pair so as to assure air flow therethrough even in situations where the motor vehicle is stationary.
Such assembly of condenser, radiator and fan forms a so-called cooling module, also commonly referred to as CRFM, standing for Condenser Radiator and Fan Module. The components of the CRFM are held together and mounted in the vehicle by means of a frame. The frame is generally of rectangular shape and surrounds the assembly of heat-exchangers. The frame includes for example two vertically extending side frame elements and two horizontal frame elements connecting the ends of the side frame elements.
One issue with standard CRFMs is the fluidic connection of the heat exchanger situated at the frontside of the CRFM, which is done by hoses that are pre- mounted on the CRFM and guided around the frame towards the CRFM —_—-_-_-_--——————————————
IE P-ESHTHO-011/LU 2 | LU102213 backside. This renders packaging more cumbersome. Also, where the frame elements include frontward extending baffles for air sealed mounting in the engine, the presence of external hoses around the side frame elements interrupts the flat sealing surface and is a potential source of air leakage.
OBJECT OF THE INVENTION The object of the present invention is to provide an improved design of cooling module that does not comprise the above mentioned drawbacks.
SUMMARY OF THE INVENTION This object is achieved by a cooling module as claimed in claim 1.
The present cooling module is particularly developed for automotive vehicles and comprises at least two heat-exchangers assembled parallel to one another by frame members. At least some of the frame members comprise mounting features configured for cooperating with corresponding mounting features in the vehicle, in particular in the vehicle forward area. In the assembled state, the heat-exchanger module has a frontside and a backside. In the vehicle, the cooling module is normally arranged with its frontside turned towards an air inlet.
According to the present invention, at least one of the frame elements includes at least one coolant channel integrated therein, the coolant channel extending in a thickness direction of the cooling module, whereby a first end of the coolant channel is at the frontside and a second end at the backside of the cooling module. The integrated cooling channels allow forwarding coolant / fluid from the frontside to the backside of the cooling unit through the frame elements. This alleviates the need for hoses guided around the frame or through the assembly. Installation into the vehicle is simplified since connections are easily accessible from the backside. The cooling module generally uses at least two side frame elements that are configured for engaging (with their internal side) with lateral sides of the heat —-_-_---—-—-—-————————————————
exchangers and provided with mounting features (on their outer side) for attaching the cooling unit in the vehicle. The side frame elements may extend over the entire lateral edge of the heat exchangers, or only partially. In embodiments the frame elements also include transverse frame members (extending in width direction) that are located at the top and bottom of the heat exchangers. In particular, side and transverse frame members can be assembled by their extremities to form a rectangular or square support frame surrounding the assembly of heat-exchangers. The frame members may generally include front baffles. The frame elements are conveniently made from plastic material, namely made by plastic molding. However this is not a limitation and the frame elements can be made from any appropriate material, plastic or metallic.
In embodiments, the side frame elements have their inner side configured with vertically extending grooves, in which corresponding tongue forming elements or parts of the heat exchangers, €.9. of the tanks, are engaged.
In general, the heat exchangers are all supported by the frame elements. In embodiments, a heat exchanger may be mounted to another heat exchanger, instead of engaging with the side frame elements. This may be the case for smaller dimensioned heat exchangers.
The coolant channels can be provided in any of the frame elements, but it is generally convenient to arrange the integrated coolant channels in the side frame elements (also known as module carriers).
The frame elements can generally be designed according to conventional practice (and standard functionalities), but at least one of them, and preferably a pair of opposite frame elements, are provided with integrated coolant channels in accordance with the invention. The realization of the integrated coolant channel can be done in various ways. in embodiments, the frame element is made one piece by injection molding and the coolant channel is formed by injection molding in the manufacture of the frame element. Alternatively, the frame element is injection molded in one ————————
piece, and the coolant channel is formed by a pipe section made from a different material and over-molded in the frame element.
In embodiments, the integrated coolant channel can be formed in a component (i.e. separate piece) that is integrated into the frame element by mechanical assembly, in particular by form combination.
In other words, the frame element is locally configured to receive the component, e.g. by way of an aperture or recess to accommodate the component, such that upon assembly the general appearance is that of a unitary component.
There again, the coolant channel can be directly formed by injection molding in the component, or can be formed by overmolding a pipe section made from a different material and over-molded in the component.
The component may include fixing means that cooperate with fixing means provided on the frame.
Such cooperating fixing means may be based on interference fit, interlocking design and/or snap fit.
Alternatively the component may be glued in place in the frame member, or fixed by screws or riveted, or generally any appropriate technique.
The coolant channel, respectively pipe section, is advantageously L-Shaped and integrated in the frame element such that a front opening of the pipe section opens in a width direction of the cooling module, whereas the rear opening extends in thickness direction.
The transversal (perpendicular) orientation of the front opening permits connection of coolant hoses to a frontside heat exchanger without having the hoses oriented to the front.
In embodiments, the front extremity of coolant channel/pipe section protrudes from the inner side of the frame element, and the rear extremity of the coolant channel/pipe section protrudes in thickness direction from the frame element.
Where the frame elements include baffles, the protruding front end of coolant channel/pipe section is however preferably arranged behind the respective baffle.
In other words, the coolant channel/pipe section does not protrude (on the frontside) beyond the baffle sealing perimeter nor interrupts the baffle sealing surface. —— —
In general, the pipe section can be made from metal, in particular aluminium (elemental or alloy), or from a plastic material different from the frame member or component. The frame member, respectively component, can be made from any appropriate plastic material, e.g. polyamide, in particular PA-66.
In general, the length of the pipe section / coolant channel (i.e. in the module’s thickness direction) corresponds at least to the thickness of one heat exchanger and an internal gap between two heat exchangers. For example, the length of the pipe section/coolant channel may correspond to the sum of 1, 2 or 3 layers of heat exchangers (or generally all layers), plus the respective inter-layer gaps, plus possibly the shroud thickness. | In embodiments, the length of the pipe section / coolant channel corresponds to the distance from the front heat-exchanger layer, to the rear most point of the fan shroud. | in embodiments, the length of the pipe section / coolant channel further includes an additional length outside the global cooling module envelope, for ease of connection. This addition length of pipe section / coolant channel protruding at the rear of the cooling module allows providing customer end points at desired locations. According to another aspect, the invention proposes a method of manufacturing a cooling module comprising as claimed in claim 20.
These and other embodiments of the invention are recited in the appended dependent claims.
The invention brings a number of benefits: - Efficient use of package. Integration of the coolant channels inside frame elements avoids cumbersome hoses guided around the frame.
- Weight reduction. - Robustness and ease of connection through the use of fixed and solid connecting portions provided by the cooling channels/pipe sections. - Reduced assembly time.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS A cooling module 10 according to an embodiment of the present invention is shown in perspective in Figs. 1 and 2. The cooling module 10 conventionally includes a number of cooling components such as heat-exchangers that are held together by a support frame 12, forming a unit that can be mounted in an automotive vehicle, in particular in a forward region of a vehicle such as the engine compartment. In the present embodiment, the cooling unit 10 is designed as a CRFM module and includes three heat exchangers, namely a first radiator 14, a condenser 16 and a charge-air cooler 18, a second radiator 19 as well as a fan unit 20, which are seen individually in Fig.3. The first radiator 14 may be a high-temperature radiator whereas the second radiator 19 may be low-temperature radiator. These components are of conventional design. The heat exchangers 14, 16, 18 and 19 each comprise an exchanger core 14.1, 16.1, 18.1, 19.1, with a plurality of exchanger tubes extending between inlet and inlet outlet tanks 14.2, 16.2,
18.2, 19.2, respectively 14.3, 16.3, 18.3, 19.3. The fluid to be cooled enters the heat exchanger via the inlet tank 14.2, 16.2, 16.2. 19.2 and flows through the tubes of the exchanger core, where it is cooled by ambient air, to the outlet tank CC ——————
14.3, 16.3, 18.3, 19.3. External fins are provided on the tubes to increase heat transfer to ambient air. In the present variant the radiators 14, 19, condenser 16 and cooler 18 are of the so-called I-type, i.e. the tubes of the exchanger core run along the horizontal direction and the inlet and outlet tanks are arranged at the opposite tube ends. Other heat-exchanger designs are however also possible.
The heat exchangers 14, 16, 18, 19 are all provided with inlet and outlet ports
14.4, 16.4, 18.4, 19.4 arranged in the inlet and outlet tanks to permit fluid communication with respective coolant fluid circuits.
The radiators 14, 19, condenser 16 and cooler 18 are held together as a single unit by means of the support frame 12, the resulting assembly forming the cooling module 10. The frame 12 is configured to support the radiators 14, 19, condenser 16 and cooler 18 and to permit fixation of the cooling module 10 in the vehicle, for example in the engine compartment at the vehicle front.
In the assembled state of the cooling module 10, the heat exchangers 14, 16, | 18, 19 are arranged in a parallel manner, in front of one another. It can also be said that the heat exchangers are arranged in a layered manner. As shown in Fig.1, the charge-air cooler 18 and radiator 19 are located at the frontside 10.1 of the cooling unit 10, on top of one another, the condenser 16 behind it and the radiator 14 at the rear (not visible in Fig.1), i.e. the backside 10.2. The fan unit | 20, which comprises an electric motor driven fan 20.1 and a fan shroud 20.2, is fixed to the rear face of the radiator, in order to draw air across the assembly of heat exchangers even when the vehicle is not moving or at low speed.
Turning to the design of frame 12, it here consists of four elements: two side elements 24, 26 connecting two transverse elements 28, 30. Referring to the (X, Y, Z) coordinate system shown in Fig.1, the side frame elements 24, 26 extend along the Z direction and the transverse elements 28, 30 extend along the Y direction. When the cooling module 10 is mounted in the engine, the Z axis is substantially vertical and the X axis generally corresponds to the longitudinal direction of the vehicle, whereby axis Y extends transversally. EE —
The four frame elements 24, 26, 28, 30 are conventionally manufactured from plastic, in particular by injection molding. They have elongate shapes, with a length corresponding at least to the adjacent edge of the largest heat exchanger, here radiator 14. They have an inner face, turned towards the heat exchangers, and an opposite outer face. The frame elements 24, 26, 28, 30 are molded with a number of functional features for reinforcement, for supporting the heat exchangers, for the frame assembly, and for mounting in the engine compartment. Within the frame 12, each heat exchanger is normally fixed and/or supported individually.
The side frame elements 24, 26, also referred to as carrier modules, are generally configured to engage with the lateral edges of the respective heat exchangers; their width (in X direction) is thus adapted accordingly. The side frame elements 24, 26 typically include longitudinal grooves on the inner face, that receive edge portions of the heat exchangers. The side frame elements 24, 26 may further include fixtures such as lugs with holes for individually fixing the heat exchangers to the frame. At both ends the side frame elements have fixing features cooperating by form engagement with the fixing features of the transverse members. On their outer face, the side frame elements have mounting features in the form of a protruding stud, extending in Y direction, for fixing the cooling unit in the vehicle. A grommet 27 is fitted over this stud.
The lower transverse element 28, also referred to as lower baffle, thus extends along the Y direction and forms the frame bottom, supporting the weight of the heat exchangers.
The top transverse element 30, also referred to as upper baffle, extends along the Y direction and closes the upper frame region. Fixation features are provided on the top transverse element 30 or in the upper region of the side frames 24, 26 for fixing the cooling module in the vehicle.
it may be noted that all four frame elements here have a respective baffle portion 24.1, 26.1, 28.1, 30.1 in the form of a flat rectangular plate extending frontward from the frame elements and inclined towards the center of the _--——{{{{
moduie.
These baffie portions permit and air-sealed mounting of the cooling unit in front of an air inlet inside the vehicle. it will be appreciated that the two side frame elements 24, 26 each include an integrated coolant channel 32 extending from the frontside to the backside, in order to carry coolant fluid from a heat exchanger arranged at the front of the module to the backside.
In this variant the second radiator 19 has its inlet and outlet ports 19.4 connected by respective hoses 19.5 to a front opening 32.1 of the coolant channel 31,. The coolant channel 32 has its rear opening 32.2 at the rear of the cooling unit 10, and can be easily connected to hoses of a coolant circuit, namely of the air conditioning system.
Hence, the coolant channels 32 extend in the thickness direction of the cooling unit 10, here parallel to the X axis (although this is not required). In the embodiment of Figs. 1 to 4, the coolant channel 32 is integrated in a component 34 that is assembled to the side frame element 24, 26. As best seen in Fig.4, the component 34 is a plastic member that is configured to be assembled at a given position in the side frame element 26. The coolant channel 32 is formed by an L-shaped aluminium pipe (designated by same reference number) that is overmolded in the component 34. It may be noticed from the figure that the aluminium pipe section 32 is only partly covered by the plastic material of the component.
A part of the lateral side of the pipe section 32 is apparent, in addition to its ends.
This pipe section 32 (or pipe fitting) may be a cylindrical pipe of constant or variable cross-section.
The length of the pipe section 32 is adapted to the thickness of the cooling module 10, or more particularly to the thickness (X direction) of the layers of heat exchangers.
In general, the length of the pipe section 32 / coolant channel corresponds at least to the thickness of one heat exchanger and an internal gap between two heat exchangers.
Here the length of the pipe section/coolant channel 32 corresponds substantially to the sum of the thicknesses of the radiator 14, condenser 16 and radiator 19, plus the respective intermediate gaps.
In other embodiments, the length of the pipe section/coolant channel can be designed to extend across the fan shroud to reach the rear of the cooling module.
Furthermore, an additional length of pipe section/coolant channel may be provided to have the rear opening 32.2 located beyond the rear face of the shroud, at a desired location (customer end point). As seen in Fig.4, the pipe section 32 is integrated in the side frame element 26 such that the front end protrudes from the side frame element 26 in a transverse direction, at the level of the heat exchanger to which it is to be connected or, as is the case here, before it (at the level of the cooler 18). The bent end of pipe section 32 with the first opening 32.1 is however arranged behind the front baffle 26.1. The opposite, rear end of pipe section 32 protrudes from the side frame element in the thickness direction. in the embodiment of Figs. 5 and 6 the side frame element, designated 26’, is made in one piece by injection molding, a pipe section 32’ being placed in the injection mold so that it is overmolded with the plastic material of the side frame element.
Here the pipe section 32’ is entirely overmolded by the plastic material, except for the two end portions with the front opening 32.1’ and rear opening 32 92°. The overall design of the side frame element 26’ is similar to that of the first embodiment, but the pipe section is directly integrated and not in an additional component element.
Accordingly, the front end 32.1’ of pipe section 32’ protrudes from the side frame element 26’ in a transverse direction (behind baffle 26.1), whereas the rear end 32.2’ protrudes from the side frame element in the thickness direction.
Fig.5 shows the inner side of the side frame element 26’, where one can see axial grooves along 38 and 40 the internal side of the side frame element 26°. In the assembled state, groove 38 receives the lateral edge of the condenser 16 and groove 42 the lateral edge of the radiator 14. Reference sign 40 indicates an internal gap between the two grooves 38 and 40, resulting in an internal gap between the two heat-exchangers,
