Definitions
- the present application is in the field of the production of heat exchangers, in particular for battery modules and in particular for motor vehicle battery modules, and relates to a heat exchanger with liquid circulation and a fluidic connector for such an exchanger.
- the invention is particularly applicable to all electric or hybrid automobiles with a battery pack or battery cells.
- the first exchangers are arranged on the battery pack housings and these exchangers are connected to a fluid circuit provided with one or more second exchangers dissipating heat into the atmosphere. Connecting exchangers can be cumbersome and reduce storage space.
- Battery modules generally comprise a frame in which the unit cells of the batteries are arranged and it is known practice to cool battery modules by means of heat exchange plates or heat exchangers, comprising panels arranged on the chassis and in which a coolant circulates.
- Heat exchangers are generally produced by means of two stamped plates and assembled together in a sealed manner and in which are formed meanders or a space for the circulation of the liquid.
- Document DE102017202552 gives examples of stamped plate heat exchangers and associated fluidic connection end pieces.
- the present application improves heat exchanger devices, by proposing a device capable of being mounted directly in contact with battery cells or on a pack of battery cells and for which the place taken up by the fluidic connections of the heat exchanger is reduced to further reduce the dimensions of an energy storage module.
- the device of the present application more particularly provides a heat exchanger provided with a base plate and a liquid circulation space formed between a plate attached to the base plate and the base plate, which comprises at least one fluidic connector, fixed on the base plate or on a return inclined relative to the base plate and connected to an inlet or outlet channel of the liquid circulation space, said connector comprising a tubular end piece , for connecting the device to a tubing of an external fluid circuit, a base provided with a recess into which the tubular nozzle opens and with a mouth for connecting to said channel, the recess forming a fluid passage between the mouth and mouthpiece, for which the recess comprises an opening on a face for fixing the connector on the base plate or on said return, the base plate or said return forming a closing wall of said recess of the base ensuring the sealing of said fluid passage.
- This embodiment reduces the size of the fluidic connector and positions it as close as possible to the assembly consisting of the base plate and the attached plate.
- the attached plate which can be a stamped plate, can in particular be a plate welded, glued or assembled by brazing on the base plate.
- the attached plate can in particular be provided with meanders forming said liquid circulation space.
- the mouth of the connector base is produced as an extension of the opening of said fixing face and, one end of the channel of the attached plate opening at the edge of the base plate , the connector is cantilevered onto the sloped return so that the connector base protrudes from the return to align the mouth of the base with the end of the channel.
- the fluidic connector advantageously does not protrude in a direction perpendicular to the upper plane of the attached plate.
- the base plate and the inclined return can be two intersecting faces of the same profile.
- the profile may constitute all or part of a housing receiving battery cells.
- the fixing face of the connector base is received on the base plate, the mouth of the base extends over a face of the base perpendicular to the face of fixing of the base in communication with one end of the channel of the attached plate.
- the connector can be positioned directly on the base plate to the right of the outlet or entry channel of the circulation space.
- the fluidic connector comprises at least one means for centering the mouth relative to said channel.
- said means consists of a pin, rod, or tongue inserting into the channel and preferably consisting of two pins or rods arranged on either side of the mouth and engaging in the channel.
- the fluidic connector may be welded or glued in position on the base plate and on the end of the channel of the insert plate. This allows the heat exchanger to be produced directly by welding or gluing the base plate assembly, insert plate and input / output connectors.
- the present application also relates to a one-piece fluidic connector for a heat exchanger produced by machining or molding which comprises a base provided with a recess and a tubular endpiece opening into the recess which constitutes a fluidic passage between a mouth of the base and a channel of the tubular end piece and for which the base has a fixing face provided with an opening for making the recess.
- Such a connector is easy to manufacture both in molding and in machining in different sizes.
- the connector being adapted to be fixed on a return inclined relative to the base plate, and the mouth is made at starting from an extension of the opening in the plane of the opening, the frame of the mouth comprising walls provided with rounded corners on a curved edge between the inclined return and the base plate.
- the connector is adapted to be fixed on the base plate and the mouth is formed from an extension of the opening in a plane perpendicular to the opening.
- FIG. 1 shows a perspective view of a first example of an assembled base plate, insert plate and connector part
- FIG. 2 shows an exploded perspective view from below of the elements of FIG. 1;
- FIG. 3 shows a perspective view from below of the connector of FIG. 1;
- FIG. 4 shows a perspective view of a second example of an assembled base plate, insert plate and connector part
- FIG. 5 shows an exploded perspective view from below of the base plate, the insert plate and an alternative embodiment of the connector of FIG. 4;
- FIG. 6 shows a rear three-quarter perspective view of the connector of Figure 5.
- the present application provides according to the examples of Figures 1 and 4 in particular a heat exchanger provided with a base plate 10, 10 'and a liquid circulation space 15 formed between the base plate and an attached plate 20, 20 'on the base plate.
- the insert plate comprises, according to the example, inlet and outlet channels 21, 22, 23 which will distribute meanders 15 of circulation of a heat transfer fluid between the insert plate and the base plate.
- the ends of the channels exit from the attached plate either, as shown in Figure 2, at a cutout of the attached plate leaving a space on the base plate, or on a peripheral edge of the attached plate and the base as shown in figure 4.
- the inlet and outlet channels can distribute a space under the base plate provided with internal bosses for dispersing a flow of the heat transfer liquid instead of meanders.
- the heat exchanger comprises an inlet fluidic connector and an outlet fluidic connector which can take two configurations which will be described below.
- the fluidic connector 30, more particularly detailed in Figure 3 comprises a base 36 extending the outlet of the channel and a tubular end piece 33 extending parallel to the attached plate.
- the tubular end piece 33 which constitutes a heat transfer fluid outlet or inlet tube for the heat exchanger, is oval in order to reduce the height of the connector.
- a cylindrical tip of revolution can however also be envisaged in this embodiment. This nozzle will make it possible to connect the exchanger to a pipe of an external fluid circuit connected, for example, to a radiator in contact with the air outside the vehicle and possibly provided with a cooling fan.
- the base constitutes a liquid passage between a mouth 38a of the connector and the tubular end piece.
- this passage is not closed at the connector, this passage being produced by a recess 38 starting from an opening on one face 40 of the connector base.
- the face 40 is a face for fixing the connector on a wall which is the base plate 10 in the case of the assembly of FIG. 1. The base plate will thus seal the passage formed by the recess 38.
- the mouth 38a is formed from an extension of the opening in the wall 40 in a plane perpendicular to this opening.
- the assembly of the attached plate 20 and the connector 30 is made on the base plate 10, the connector comprising pins or rods 41 which come to be introduced into the opening of the channel 21 so that the mouth 38a of the base is positioned correctly in front of the inlet or outlet of the channel.
- the connector and the attached plate are welded for example by laser welding or glued to the base plate.
- the base plate, the attached plate and the connector can be metallic, in particular aluminum or steel, but also filled polymer or ceramic depending on the heat exchange performance obtained with these materials.
- the base plate 10 has a return 12 inclined relative to the base plate.
- the base plate and the inclined return can be two walls of an angle or any other type of profile possibly at 90 ° to each other.
- the connector 31 can be fixed on the return 12 and connected to a channel 21, 22 for entering or leaving the liquid circulation space which comes to the edge of the base plate.
- the connector 31 also comprises a tubular end piece such as a straight end piece 34 in FIG. 4 or a end piece 35 provided with a profile 35a, 35b, 35c, 35d ensuring correct fixing and sealing for a pipe connected to the connector as shown in Figures 5 and 6.
- the connector also comprises a base 37 provided with a recess 39, into which the tubular end opens, and a mouth 39a for connection to said channel.
- the recess forms a fluid passage between the mouth 39a and the mouthpiece 34, however, in this embodiment the mouth is in a plane parallel to the opening of the recess and not in a plane perpendicular to this opening. It is obvious to those skilled in the art that in an embodiment for which the return would form a non-flat angle other than 90 ° with the base plate, the mouth could also extend in a secant, non-perpendicular plane, when opening the recess.
- the connector is fixed cantilever on the inclined return 12 so that the connector base protrudes from the inclined return to align the mouth 39a of the base with the end of channel 22, 23 of the attached plate opening at the edge of base plate 10 '.
- the return makes an angle of 90 ° with the base plate and the mouth and end of the channel are perpendicular to the base plate.
- the cutting of the end of the channel can be made in a plane parallel to the return to apply to the mouth.
- the fluidic connector shown also comprises, on either side of the mouth, pins or rods 41 for centering the mouth with respect to said channel. However, it is possible to position a single pin or a tongue to effect the positioning of the fluidic connector relative to the channel.
- this connector comprises, at the level of a frame 42, 44 of the mouth, side walls 42 provided with roundings 43 intended to match the curvature 3 of the ridge between the inclined return 12 and the base plate 10 'and an upper wall 44 joining the end of the plate attached above this curvature.
- the fluidic connector 31, 32 is welded or glued in position on the base plate, the return and on the end of the channel of the attached plate at the same time as the attached plate, the assembly being carried out as shown in the figure figure 5 with the connector rods 41 introduced into the channel terminations 22, 23.
- fluidic connectors 30, 31, 32 are each made in a single piece by machining or molding and comprise a base 36, 37 provided with a recess 38, 39 and whose fixing face 40, 40 'is provided with an opening for making the recess connecting the mouth of the base and the tube of the mouthpiece.
- the fluidic connector does not protrude from the lateral dimensions of the battery module and provides little extra thickness relative to the attached plate.
- the fluidic connector does not add any additional thickness relative to the attached plate which contains the space for the circulation of the heat transfer fluid.
- the offset of the connection with the external fluidic circuit being in the continuity of a channel of the attached plate it is not necessary to provide a hole in the attached plate and the connection between the fluidic connector and the attached plate is produced by simple stamping of the attached plate.
- the realization of the fluidic connector which is applied to the base plate or its return allows the use of a laser welding process in order to seal the base plate / attached plate / connector assembly in a single operation .
- the exchanger is compact and easily connectable.
- the invention is not limited to the examples shown and, for example, the two types of connectors and assembly can coexist on the same exchanger, which gives great flexibility for the installation of the inputs / outputs of the exchangers.
- the output of the ends of the connectors of Figure 6 can be made on another face of the base, for example the underside according to Figure 6.
