Description

Technical Field

[0001] The present invention relates to an eddy current separation device for fluid transfer circuits, particularly in motor vehicles, such as an eddy current separation device for heat transfer circuits in motor vehicles. Background Technology

[0002] Some fluids may contain air bubbles. This is particularly true of heat transfer fluids used in the heat transfer circuits of motor vehicles, which consist of a mixture of water and ethylene glycol and may contain air bubbles or vapor bubbles.

[0003] To optimize the performance of the loop, these bubbles are preferably separated from the fluid, and eddy current separation devices are known to be used for this purpose.

[0004] This device includes an internal chamber connected to a fluid inlet and two outlets, one for a liquid portion and the other for a gaseous portion of the fluid. The device is configured such that the fluid arriving through the inlet rotates within the chamber about axis A to form vortices for separating the liquid and gaseous portions. The centrifugal effect of the vortices allows the liquid portion to be separated radially outward (relative to axis A) and the gaseous portion radially inward by means of density difference. The liquid portion exits the chamber through a liquid outlet typically located at the outer periphery of the chamber, while its gaseous portion exits the chamber through a gas outlet typically located at axis A.

[0005] Devices for dual-loop systems also exist, where two loops circulate two different fluids (same or different) connected to the same eddy current separator. However, existing solutions, particularly for fluid velocities above approximately 10 L / min, do not allow for optimized operation. Furthermore, these devices fail to effectively isolate the two independent loops, which can have negative consequences, especially regarding heat exchange between the two loops, particularly when they operate at different temperatures.

[0006] In particular, the present invention aims to solve some or all of the problems mentioned above. Summary of the Invention

[0007] This invention relates to an eddy current degassing device for a fluid transfer circuit, particularly in a motor vehicle, the device comprising:

[0008] - A first internal chamber, which is connected to a first inlet for fluid and a second outlet for the liquid portion and the gas portion, the second outlet extending upward along axis A.

[0009] - A first flow guide, protruding within a first chamber, forces fluid arriving through the first inlet to form a vortex around axis A within the first chamber, thereby separating the liquid and gaseous portions of the fluid, which are then discharged through a first outlet and a second outlet, respectively.

[0010] The device is characterized in that it further comprises:

[0011] - A second internal chamber, connected to a second inlet for the fluid and a third outlet for the liquid portion and a fourth outlet for the gas portion, the fourth outlet of the gas portion extending at least partially upward along said axis A, and

[0012] - A second flow guide, protruding from the second chamber, forces the fluid arriving through the second inlet to form a vortex around axis A within the second chamber, thereby separating the liquid and gaseous portions of the fluid, which are then discharged through a third and a fourth outlet, respectively.

[0013] Furthermore, the second chamber is located above the first chamber, and the second outlet extends through the second chamber to the level of the fourth outlet.

[0014] Therefore, the present invention proposes, in particular, to provide a second outlet for the gas portion of the first chamber, which rises to the level of a fourth outlet. Specifically, this arrangement prevents bubbles collected in the first chamber and discharged through the second outlet from being carried into the second chamber. This arrangement also allows for the avoidance of flow exchange between the two chambers, and thus limits heat exchange between them, thereby limiting heat exchange between the two independent sub-circuits supplying the first and second chambers respectively. This limitation of heat exchange allows the sub-circuits to operate at different temperatures while sharing a common separation device.

[0015] This invention also enables efficient operation at high flow rates (especially above 10 L / min).

[0016] The device according to the invention may include one or more of the following features, which may be used individually or in combination with each other:

[0023] - Multiple fluid connection end caps protruding from the main body, the multiple fluid connection end caps forming a first inlet, a second inlet, and a first outlet, a third outlet and a fourth outlet respectively;

[0024] The device can also be made from three components:

[0025] - A first component, which forms the lower part of the main body, and a connecting end cap for the first inlet and the first outlet.

[0026] - A second component, which forms the upper part of the main body, and a connecting end cap for the second inlet, the third outlet, and the fourth outlet, and

[0027] - A third component, which is installed inside the main body and forms a second outlet;

[0028] - The third component is in the form of an inverted funnel and includes: an upper cylinder forming a second outlet; and a lower dome mounted in the body to define a first chamber and a second chamber, the dome including a central hole aligned with axis A and leading to the cylinder;

[0037] --The average internal diameter of the first outlet and the third outlet is between 8 mm and 32 mm, preferably between 12 mm and 20 mm, and for example 16 mm;

[0038] --The fourth outlet has an average internal diameter between 6 mm and 22 mm, preferably between 12 mm and 20 mm, and for example 16 mm;

[0039] --The outer diameter of the device or body is between 40mm and 80mm, preferably between 50mm and 60mm, and for example about 55mm;

[0056] Figure 1 and Figure 2 A vortex degassing device 1 according to the invention is shown for a transfer loop of a first fluid F1 and a second fluid F2 (particularly a heat transfer fluid used in motor vehicles). The loop includes, for example, a first sub-loop and a second sub-loop, in which the first fluid F1 flows and the second fluid F2 flows. Specifically, these sub-loops are independent of each other. Fluids F1 and F2 are, for example, the same, and particularly a mixture of water and ethylene glycol in a liquid state, in which air bubbles or vapor bubbles flow. Device 1 allows for the separation of the liquid and gaseous portions of fluids F1 and F2. In this application, "gaseous portion" refers to a gas that may contain droplets or a gas-rich liquid.

[0057] Specifically, device 1 is made of a plastic material.

[0058] Device 1 includes a first internal chamber 10 connected to a first inlet 11 of a first fluid F1 and a second outlet 13 connected to a liquid portion and a gas portion. The second outlet 13 extends upward along axis A. The first inlet 11 and the first outlet 12 are located at different positions along axis A, for example. The first inlet 11 is located, for example, above the first outlet 12.

[0059] The first chamber 10, the first entrance 11, the first exit 12, and the second exit 13 are part of the first sub-circuit.

[0060] The device 1 further includes a second internal chamber 20. The second chamber 20 is located above the first chamber 10 along axis A. The second internal chamber 20 is connected to a second inlet 21 of the second fluid F2 and a third outlet 22 of the liquid portion and a fourth outlet 23 of the gas portion. The fourth outlet 23 of the gas portion extends at least partially upward along axis A. The second inlet 21 and the third outlet 22 are located at different positions, for example, along axis A. The second inlet 21 is located above the third outlet 22, for example.

[0061] The second chamber 20, the second entrance 21, the third exit 22, and the fourth exit 23 are part of the second sub-circuit.

[0062] Unless otherwise specified, the adjectives inner / inner and outer / outer refer to radial directions, such that the inner (i.e., radially inner) part of an element is closer to axis A than the outer (i.e., radially outer) part of the same element. Similarly, the terms above / below and upper / lower refer to the position of an element along axis A relative to the ground.

[0063] Specifically, the first inlet 11 and the second inlet 21 each have an average internal diameter between 8 mm and 32 mm, preferably between 12 mm and 20 mm, and for example 16 mm.

[0064] Specifically, the first outlet 12 and the third outlet 22 each have an average internal diameter between 8 mm and 32 mm, preferably between 12 mm and 20 mm, and for example 16 mm.

[0065] The fourth outlet 23 has an average internal diameter between 6 mm and 22 mm, preferably between 12 mm and 20 mm, and for example 16 mm.

[0066] The device 1 also includes a first guide vane 14 protruding into the first chamber 10. The first guide vane 14 enables the guidance and acceleration of the first fluid F1 arriving through the first inlet 11. Thus, when the first fluid arrives through the first inlet 11, the first fluid F1 is forced to form a vortex around axis A in the first chamber 10 to separate the liquid and gaseous portions of the first fluid F1. The liquid and gaseous portions of the first fluid F1 are discharged through the first outlet 12 and the second outlet 13, respectively.

[0067] The device 1 also includes a second guide vane 24 protruding into the second chamber 20. The second guide vane 24 enables the guidance and acceleration of the second fluid F2 arriving through the second inlet 21. Therefore, when the second fluid arrives through the second inlet 21, the second fluid F2 is forced to form a vortex around axis A in the second chamber 20 to separate the liquid and gaseous portions of the second fluid F2. The liquid and gaseous portions of the second fluid F2 are discharged through the third outlet 22 and the fourth outlet 23, respectively.

[0068] The second outlet 13 extends through the second chamber 20 to the level of the fourth outlet 23. The second outlet 13 extends specifically along axis A above the second inlet 21. Therefore, bubbles in the lower loop (i.e., the first sub-loop) are not carried away by the fluid flowing in the second chamber 20 (i.e., the second sub-loop).

[0069] The second outlet 13 includes a free upper portion 13a, which is axially spaced from or surrounded by the fourth outlet 23. The distance L1 between the free upper portion 13A of the second outlet 13 and the second inlet 21, measured along axis A, is greater than or equal to 5 mm, and preferably less than or equal to 15 mm. The second outlet 13 has a minimum channel cross-section S1, and the fourth outlet 23 has a minimum channel cross-section S2, where S1 = k * S2, k is particularly between 0.8 and 1.2, and preferably equal to 1. Therefore, the channel cross-sections S1 and S2 of the bubbles in the two chambers 10 and 20 are the same or very similar. The degassing and filling capacity of each chamber in chambers 10 and 20 is then balanced.

[0070] Specifically, the second outlet 13 is located at the center of the second chamber 20, so that the second outlet does not interfere with the tangential and / or circumferential flow of the second fluid F2 in the second chamber 20.

[0071] The internal shapes of these chambers, especially the internal shapes of the flow guides 14 and 24, are not necessarily the same. This allows for adaptation to the specific conditions of fluid flow rate and gas volume in each sub-loop.

[0072] Device 1 includes a generally cylindrical body 2, the axis of rotation of which coincides with axis A and extends vertically thereon. Body 2 includes a lower portion 3, which includes a first chamber 10. Body 2 includes an upper portion 4, which includes a second chamber 20.

[0073] The device 1 or the main body 2 has an outer diameter D1 measured perpendicular to axis A, which is between 40 mm and 80 mm, preferably between 50 mm and 60 mm, and for example about 55 mm.

[0074] The device 1 or the main body 2 has a length or height H1 measured along axis A, which is between 80 mm and 180 mm, preferably between 110 mm and 150 mm, and for example 130 mm.

[0075] The device 1 also includes fluid connection end caps 11a, 21a, 12a, 22a, and 23a protruding from the main body 2, which respectively form a first inlet 11, a second inlet 21, a first outlet 12, a third outlet 22, and a fourth outlet 23.

[0076] End cap 11a corresponds to the first inlet 11. Here, end cap 11a extends along axis B. Axis B lies in a plane perpendicular to axis A. This axis B is oriented to be tangent to a circumference centered on axis A.

[0077] End cap 21a corresponds to the second inlet 21. Here, end cap 21a extends along axis D. Axis D lies in a plane perpendicular to axis A. This axis D is oriented to be tangent to a circumference centered on axis A.

[0078] End cap 12a corresponds to the first outlet 12. Here, end cap 12a extends along axis C. Axis C lies in a plane perpendicular to axis A. This axis C is oriented to be tangent to a circumference centered on axis A. Here, end cap 12a is located below end cap 11a along axis A.

[0079] End cap 22a corresponds to the third outlet 22. Here, end cap 22a extends along axis E. Axis E lies in a plane perpendicular to axis A. This axis E is oriented to be tangent to a circumference centered on axis A. Here, end cap 22a is located below end cap 21a along axis A.

[0080] Here, axes B, C, D, and E are in the same plane, particularly parallel to axis A, but they can also be arranged in different planes.

[0081] The tangential positions of the first inlet 11 and the second inlet 21 enhance the eddy current effect of the device 1. Similarly, the tangential positions of the first outlet 12 and the third outlet 22 enhance the eddy current effect of the device 1. The first inlet 11 and the second inlet 21, as well as the first outlet 12 and the third outlet 22, can be located in relation to... Figure 1 and Figure 2 The embodiments shown are positioned tangentially to chambers 10 and 20 in different relative orientations to accommodate the architecture of the circuit on which device 1 is mounted.

[0082] Therefore, in this invention, the fluid inlet to each chamber is optimized (vertically and horizontally) to enhance the vortex effect of the two sub-loops, and the two chambers are superimposed. Thus, each chamber is analogous to an optimized single-flow system.

[0083] like Figure 3 , Figure 4a , Figure 4b , Figure 5a , Figure 5b , Figure 6a , Figure 6b As shown, device 1 is specifically made of three components P1, P2, and P3.

[0084] like Figure 3 As shown, the first component P1 forms the lower part 3 of the main body 2 and forms connecting end caps 11a and 12a, which form the first inlet 11 and the first outlet 12.

[0085] like Figure 4a and Figure 4b As shown, the second component P2 forms the upper part 4 of the main body 2, and forms connecting end caps 21a, 22a, and 23a, which form the second inlet 21, the third outlet 22, and the fourth outlet 23. The third flow guide 24 is specifically integrated into the second component P2.

[0086] like Figure 5a and Figure 5b As shown, the third component P3 installed inside the main body 2 forms the second outlet 13.

[0087] The third component P3 is in the form of an inverted funnel. The third component P3 includes an upper cylinder 31 that forms the second outlet 13. The third component P3 also includes a lower dome 32.

[0088] The lower dome 32 is installed in the main body 2 to define the first chamber and the second chamber. Figure 5a and Figure 5b (Not shown in the image). The dome 32 includes a central hole 33 aligned with axis A and leading to cylinder 31.

[0089] Dome 32 includes an outer periphery 34 configured to axially and / or radially clamp the mating edges of the first member P1 and the second member P2 (respectively at...). Figure 3 The middle is marked as 19 and in Figure 4a and Figure 4b The dome 32 is located between the first and second components (marked as 29). In particular, the dome is clamped between the joint edges of the first and second components, thus allowing the first and second chambers to be separated in a sealed manner.

[0090] The first flow deflector 14 is integrated, for example, into the third component P3. In particular, the first flow deflector 14 is connected to the dome 32 and extends along axis A from the inside to the outside of the dome 32.

[0091] As a result of the present invention, the integral component (third component P3) separates the two internal volumes of the two chambers and ensures the guidance of the bubbles captured in the first chamber.

[0092] like Figure 6a and Figure 6b As shown, the dome 32 includes at least one indexing element 35, for example, at its outer periphery 34. This indexing element 35 is configured to mate with a corresponding element 15 of the first member P1 in a form-fitting manner, so that the third member P3 has a predetermined angular position relative to the first member P1 about axis A. Specifically, this ensures that the first guide 14 (when carried by the third member P3) is correctly positioned relative to the first inlet 11 of the first member P1. The device 1 here includes two indexing elements 35, specifically two lugs. The device 1 here also includes two corresponding elements 15 of the first member P1, specifically two ribs, the shapes of which are complementary to the lugs, so that the third member P3 can be indexed on the first member P1 about axis A.

[0093] Therefore, the first fluid F1 enters the chamber 10 through inlet 11 and is then set to rotate, particularly due to the tangential position of the first inlet 11. Thus, the first fluid F1 undergoes rotational motion and is further guided and accelerated by the first guide 14. The first fluid F1 rotates and flows from top to bottom within the first chamber 10, moving along... Figure 2 A vortex is formed in the direction marked V1. During this rotation, the heavier liquid portion separates from the lighter gas portion through centrifugal effect. The liquid portion flows through the first tangentially oriented outlet 12, while the gas portion rises along axis A through the orifice 33 of the dome 32 in the cylinder 31 and is discharged through the second outlet 13. This prevents bubbles collected in the first chamber 10 from being drawn into the chamber 20. The small diameter of the cylinder 31 allows for limited interference with the operation of the second chamber 20.

[0094] Additionally, the second fluid F2 enters the second chamber 20 through the second inlet 21 and is then configured to rotate due to the tangential position of the second inlet 21. Therefore, the second fluid F2 undergoes rotational motion and is further guided and accelerated by the second guide 24. The second fluid F2 rotates and flows from top to bottom within the second chamber 20, moving along... Figure 2 A vortex is formed in the direction marked V2. During this rotation, the heavier liquid portion separates from the lighter gas portion through centrifugal effect. The liquid portion flows through the third tangentially oriented outlet 22, while the gas portion rises along axis A and is discharged through the fourth outlet 23.

[0095] like Figure 7 As shown, at least one annular seal 36 may be installed between the outer periphery 34 of the dome 32 and the first member P1 and / or between the outer periphery 34 of the dome 32 and the second member P2. The annular seal 36 minimizes exchange between the two chambers 10, 20, and thus between the two sub-circuits.

[0096] like Figure 8a , Figure 8b , Figure 8c As shown, the circular engagement edges of the first member P1 and the second member P2 can have a coplanar connection extending along plane P. The circular engagement edge of the first member P1 is configured to be positioned against the circular edge of the second member P2 along plane P. The coplanar connection of the circular engagement edges of the two members P1 and P2 allows for different variations in the angular orientation of the first member P1 relative to the second member P2 about axis A, in order to particularly accommodate the loop in which device 1 will be positioned. Furthermore, these different configurations of device 1 can be achieved using a single tool for molding members P1 and P2. It can be seen that in all the illustrated embodiments, the first inlet 11 and the second inlet 21, as well as the first outlet 21 and the third outlet 22, are always tangentially positioned. Furthermore, the first inlet 11 is always located above the first outlet 12, and the second inlet 21 is always located above the third outlet 22. Of course, other configurations of the first inlet 11 and the second inlet 21, as well as the first outlet 21 and the third outlet 22, are also possible without departing from the scope of the invention.

[0097] Figure 9a , Figure 9b Alternative embodiments of the invention are shown in which the end caps 11a, 12a, 21a, and 22a (i.e., the type of connection) are of different types. These end caps include, for example, threads, snap-fit ​​systems, or any other type of means for connecting to a fluid circuit. Figure 9a In this case, end caps 21a and 22a include, for example, threads, while end caps 11a and 12a include another type of connecting device. Figure 9bIn this configuration, the four end caps 11a, 12a, 21a, and 22a include a snap-fit ​​system. This allows the connection type of each end cap to be selected independently of the other end caps.

[0098] like Figure 10 As shown, the present invention also relates to a fluid transfer circuit F1, F2, particularly a fluid transfer circuit F1, F2 for a motor vehicle, the fluid transfer circuit including at least one device 1 as described above. The first chamber 10 and the second chamber 20 of the circuit are connected to a common buffer tank 41 of the fluid transfer circuit via a fourth outlet 23.

[0099] The present invention also relates to a method for using the device 1 described above in fluid transfer circuits F1, F2, particularly in fluid transfer circuits F1, F2 of motor vehicles, wherein the same fluids F1, F2 (e.g., heat transfer fluids) flow in a first chamber 10 and a second chamber 20. These fluids F1, F2 are at the same pressure and at different temperatures.

[0100] This invention can be applied to any type of fluid that may contain air bubbles. Preferably, this invention was developed in the context of thermal control circuits in motor vehicles.

[0101] This invention is particularly applicable to the broader automotive field (trucks, buses, public works machinery, agricultural machinery, etc.) for all vehicles equipped with fluid transfer circuits (e.g., heat transfer circuits), regardless of the propulsion mode of these vehicles (internal combustion engine, electric motor, hybrid engine, etc.).
