Title of the invention: Fluidic communication block with improved heat dissipation for a heat exchange device. Technical field

[0001] The invention relates to heat exchange devices provided with fluidic communication blocks configured to supply or collect one or more heat transfer fluids within said devices. Previous technique

[0002] In the context, particularly in the automotive industry, where several heat exchange devices are assembled in close proximity to one another, the problem encountered by the art is that certain fluids distributed at high temperatures within the heat exchange device will emit heat radiation from the fluid communication blocks. This radiation can then affect components sensitive to high temperatures, for example, around 180°C, such as heat exchange device manifolds made of plastic. Under the effect of the heat transmitted to these components, their structure can be weakened or even degraded. In the automotive industry, for example, it is common for a heat exchange device such as a front-end radiator of the vehicle to serve as a mounting structure for another heat exchange device such as an air-gas cooler.A fluidic communication block of the cooler may then be located near a plastic wall of the radiator, this plastic being of a grade having a heat tolerance of less than 180°C. By proximity, we mean a distance between these components of less than 10 millimeters, preferably less than or equal to 5 millimeters. Description of the invention

It should also be noted that these figures only show a few examples of embodiments of the invention. Detailed description

[0040] Fig. 1 illustrates a fluidic communication block 10 of a first heat exchange device 100, said device 100 being configured to permit the exchange between a first and a second heat transfer fluid, said fluidic communication block 10 comprising a channel 1 configured for the admission or expulsion of the first heat transfer fluid into the first heat exchange device 100, said fluidic communication block 10 being characterized in that it comprises a heat dissipation device 2 configured to reduce the temperature of the fluidic communication block 10 when the first heat transfer fluid enters or exits the channel 1.

[0041] Thus, the fluid communication block 10 has a lower temperature than the state of the art when the first heat transfer fluid flows through channel 1. Consequently, the thermal radiation from the fluid communication block 10 is attenuated when a hot fluid enters or exits this block, preventing damage to the surrounding parts of other components located near the first heat exchange device 100.

[0042] In the example of [Fig. 1], the heat exchange device 100 is a gas cooler. This heat exchange device 100 comprises the fluid communication block 10, which is fixed to a collector box that distributes the first heat transfer fluid into a channel bundle. This channel bundle exchanges heat with a second heat transfer fluid, for example, air, which circulates between the spaced channels of the bundle. The channel bundle can be formed by tubes or plates that create the circulation channels for the first heat transfer fluid. Fins are arranged between these tubes to increase heat exchange between the tubes and the air.

[0043] Preferably, said channel 1 of the fluidic communication block 10 is an inlet channel of the first heat transfer fluid in the first heat exchange device 100.

[0044] The fluidic communication block 10 comprises a single channel 1 for the intake or expulsion of the first heat transfer fluid.

[0049] The 211 studs are either frustoconical, pyramidal, cylindrical, hemisphere, parallelepiped or prismatic in shape.

[0050] The plots 211 are of the same dimensions or can be of variable dimensions.

[0051] The studs 211 are distributed over at least a portion of at least one lateral face 12, preferably on a portion located opposite channel 1.

[0052] The studs 211 are uniformly distributed over at least one lateral face 12.

[0053] In a manner not illustrated, the plots 211 can be distributed in an evolving manner on the less a lateral surface 12 with more studs 211 opposite channel 1 than on the rest of at least one lateral face 12.

[0054] The studs 211 can be aligned in rows along a first direction and / or along a second direction perpendicular to the first direction. Alternatively, the studs 211 can be staggered on at least one lateral face 12.

[0055] According to a second embodiment of the invention, illustrated in [Fig.3] and as an alternative to the studs, the projections 21 are ribs 212 extending over the entire length of at least one lateral face 12 comprising the projections 21.

[0056] The ribs 212 are straight or curvilinear.

[0057] The ribs 212 are arranged with a principal elongation direction secant, preferably orthogonal, to the principal elongation dimension of the channel 1 which corresponds to the direction of circulation of the first heat transfer fluid, as illustrated in [Fig.3].

[0058] Alternatively, the ribs 212 are arranged with a main elongation direction parallel to the main elongation dimension of the channel 1 which corresponds to the direction of circulation of the first heat transfer fluid.

[0059] The ribs 212 can have a constant width over their entire length.

[0060] The ribs 212 can have a variable width along their length.

[0061] The ribs 212 may have different widths, preferably at least two different widths. By two different widths, we mean that one or a group of ribs 212 has a first width dimension and that one or another group of ribs 212 has a second width dimension, different from the first width dimension.

[0062] The ribs 212 have the same height or can have a variable height.

[0063] Whether for the first or second embodiment of the invention, the fluidic communication block 10 may include means for fixing 13 of a conduit with the channel 1.

[0067] The first heat exchange device 100 includes a distribution box for the first heat transfer fluid, the fluidic communication block with the heat dissipation device 2 being of a width less than or equal to the width of the distribution box for the first heat transfer fluid.

[0068] The first heat exchange device 100 includes a mounting device 30 configured to fix the first heat exchange device 100 onto a second heat exchange device.

[0069] The mounting device 30 is a single piece of the fluidic communication block 10.

[0070] The mounting device 30 includes an outer surface which also includes the heat dissipation device 2.

[0071] The mounting device 30 is separated from the fluidic communication block 10. This has the advantage of thermally decoupling the fluidic communication block 10 from the second heat exchange device and thus limiting heat exchange between them.
