Definitions
- An electric or hybrid car comprises a heating, ventilation and/or air conditioning installation for a motor vehicle and a refrigerant fluid loop configured to vary the temperature inside its passenger compartment, and in particular to heat it in winter and to cool it down in summer.
- the temperature of the passenger compartment is modified in particular by means of the refrigerant fluid circulating in the refrigerant fluid loop between a heat exchange device arranged in the vehicle in the vicinity of the passenger compartment, and a heat exchanger located in contact with the ambient air, in front of the vehicle.
- the coolant circulating in the coolant loop absorbs or releases calories at the heat exchanger or the heat exchange device depending on the heating or cooling needs of the passenger compartment.
- the cooling of the condensation droplets may form frost locally on the spacers between the heat exchanger tubes. heat. Such a presence of frost generates obstacles to the passage of air through the heat exchanger and therefore tends to reduce the thermal capacities of the heat exchanger.
- the present invention aims to remedy this drawback, by proposing a refrigerant loop, and more particularly a heat exchanger, making it possible to limit the formation of frost on the latter.
- the invention therefore makes it possible to increase the thermal capacities of the heat exchanger and therefore of the refrigerant fluid loop.
- a connection device associated with the at least one refrigerant fluid collector comprises a refrigerant inlet split into a first fluid inlet channel connected to the fluid inlet portion of the first ch collecting amber and in a second fluid inlet channel connected to the fluid inlet portion of the second collecting chamber, and a coolant fluid outlet conduit making the junction between a first fluid outlet channel connected to the portion fluid outlet of the first collection chamber and a second fluid outlet channel connected to the fluid outlet portion of the second collection chamber.
- the two inlet channels formed in the connection flange extend perpendicular to each other, and/or in which the two outlet channels formed in the connection flange extend extend perpendicular to each other.
- the tubes allow the circulation of the refrigerant fluid within the heat exchange surface, and convey the fluid either to the first collecting chamber or from it, or to the second chamber. manifold or from it.
- the tubes are stacked in a stacking direction according to an alternation between the tubes of the first set and the tubes of the second set.
- the tubes are stacked so that the heat exchange surface comprises an alternation between a tube from the first set and a tube from the second set.
- This alternation thus forms a layout pattern, which is repeated from one end to the other of the heat exchange surface in a stacking direction of the tubes which is perpendicular to their direction of elongation.
- the heat exchanger comprises at least a first refrigerant circuit consisting of the first fluid inlet channel of the connection device, of the fluid inlet portion of the first collecting chamber of the first coolant manifold fluidically connected to the tubes of the first set, of the tubes of the first set, of the first collecting chamber of the second manifold fluidically connected to the tubes of the first set, of the fluid outlet portion of the first collecting chamber of the first refrigerant manifold fluidly connected to the tubes of the first set and the first fluid outlet channel, the first fluid inlet channel being configured to be fluidly connected to a first portion of the refrigerant loop and the first outlet channel of fluid being configured to be fluidically connected to a second portion of the refrigerant fluid loop, the heat exchanger comprising at least a second circuit of refrigerant fluid consisting of the second fluid inlet channel of the connection device, of the portion fluid inlet of the second collecting chamber of the first coolant manifold fluidically connected to the tubes of the second set, of the tubes of the second
- the heat exchange surface 2 comprises tubes 5 which are configured to channel the refrigerant fluid from one collector to another. These tubes 5 thus extend longitudinally between the first coolant manifold 3 and the second coolant fluid manifold 4, being stacked in a stacking direction E, which corresponds to a vertical direction of the heat exchanger 1.
- the first refrigerant fluid collector 3 is split into two collecting chambers 30 and 31, namely a first collecting chamber 30 and a second collecting chamber 31, and the second cooling fluid collector 4 is also split into two collecting chambers 40 and 41, namely a first collecting chamber 40, and a second collecting chamber 41.
- the first collecting chamber 30 and the second collecting chamber 31 of the first refrigerant fluid collector 3 are aligned in a longitudinal direction, with the first collecting chamber 30 which is located between the heat exchange surface 2 and the second collecting chamber 31.
- connection device 68 comprises a connection flange 8 secured to the first refrigerant fluid manifold and consisting here of a substantially rectangular housing within which are made of hollow tubular portions to form the various channels.
- the first fluid inlet channel 60 is connected to the fluid inlet portion 300 of the first collection chamber 30, and the second fluid inlet channel 61 is connected to the fluid inlet portion 310 of the second collecting chamber 31.
- the first fluid outlet channel 70 is connected to the fluid outlet portion 301 of the first collecting chamber 30, and the second fluid outlet channel 71 is connected to the fluid outlet portion 311 of the second collecting chamber 31.
- the first fluid inlet channel 60 and the second fluid outlet channel 71 are connected to their corresponding collecting chamber portion via a tubular element 82 .
- Figure 2 is a sectional view of part of the tubes 5 configured to channel the refrigerant fluid and of the first refrigerant fluid manifold 3.
- the tubes 5 are stacked in the stacking direction E alternately between the tubes of the first set 5A and the tubes of the second set 5B.
- This alternation results in the repetition of an arrangement pattern composed of a tube from the first set 5A and a tube from the first set 5B, this arrangement pattern being repeated in the stacking direction E.
- the alternation between tube of the first set 5A and tube of the second set 5B extends from one vertical end to the other of the exchange surface 2.
- the first collecting chamber 30 and the second collecting chamber 31 are separated by a dividing wall 32.
- This dividing wall 32 has a first face and a second face, the first face being facing the first collecting chamber 30 while the second face is facing the second collecting chamber 31.
- the separating wall 32 has windows 320 able to let the tubes of the second set pass 5B, so that these tubes open into the second collecting chamber 30.
- the heat exchange surface 2, the sealing wall 34, the first collecting chamber 30, the separating wall 32 and the second collecting chamber 31 are aligned along a longitudinal direction, which corresponds to the direction of tube extension 5.
- the windows 320 and the slots 340 are formed at regular intervals, respectively, in the partition wall 32 and the sealing wall 34. Such openings in the partition walls 32 and sealing 34 form cylinders for receiving the tubes. 5.
- these receiving cylinders all have a similar shape, the outer profile of the tubes being the same whether they form part of the first set of tubes or of the second set of tubes. Additionally, provision may be made for the outer profile of the tubes of the first set to be different from the outer profile of the tubes of the second set, and for the slots and the windows to have, in order to cooperate with their respective tubes, profiles which may vary. In this way, foolproofing means are formed which make it possible to ensure that a tube from the first set is not mounted in place of a tube from the second set.
- FIG. 3 is a perspective view of the connection device 68 of the heat exchanger 1, which makes the connection flange 8 mentioned above with reference to FIG. 1 more particularly visible.
- the body 80 of the connection flange 8 is a substantially rectangular box, one longitudinal end face 85 of which is pressed against the first coolant manifold 3.
- the housing forming a flange body has a connection face 84 on a transverse end face.
- This connection face 84 is pierced with two connection orifices 63, 73 to which the inlet fluid 6 and the fluid outlet conduit 7.
- connection orifices of the fluid inlet and outlet ducts may be arranged on a face other than the illustrated transverse end face, or else that they are distributed over two distinct faces and in particular over the two opposite transverse end faces of the casing, and provision may be made for the tubular elements 82 to be connected on a face other than the first vertical end face. It is however notable that the face of the housing of the flange body on which the tubular elements are attached is substantially perpendicular to the connection face.
- the longitudinal end face 85 pressed against the collector, and more particularly against the outer wall 33 of the first collector 3, has a concave shape, which is complementary to a convex shape of the outer wall 33 of the first collector 3. This complementarity of the complementary face 85 and of the outer wall 33 allows easy assembly of these two elements, and ensures their relative maintenance.
- FIG. 3 illustrates a connection device 68 for which the fluid inlet channels 60 and 61 are perpendicular to each other, and the fluid outlet channels 70 and 71 are perpendicular to each other, so that they lead to perpendicular faces.
- the present invention intends to cover, in which the fluid inlet channels 60 and 61 would be in continuity with each other so as to open out on opposite faces, and / or in which the fluid outlet channels 70 and 71 are in continuity with each other so as to open out on opposite faces.
- Some tips 830 may have a conical shape, as is the case for the fluid inlet 60 and fluid outlet 70 channels according to the embodiment illustrated in the present figure. This conical shape allows the channels in particular to pass through the second collecting chamber 31 and the separating wall 32 without being in contact with the tubes of the second set 5B, in order to open into the first collecting chamber 30 into which the tubes of the first set 5A also open. .
- the sealed partition 9 makes it possible to operate a physical and fluidic separation between, on the one hand, the fluid inlet portion 300 of the first collecting chamber 30, the first fluid inlet channel 60, the fluid outlet portion 311 of the second collecting chamber 31 and the second fluid outlet channel 71, and on the other hand the fluid outlet portion 301 of the first collecting chamber 30, the first fluid outlet channel 70, the inlet portion of fluid 310 from the second collecting chamber 31 and the second fluid inlet channel 61.
- the heat exchanger 1 comprises at least a first refrigerant circuit 50A consisting of the first fluid inlet channel 60 of the connection device 68, of the fluid inlet portion 300 of the first collecting chamber 30 of the first collector refrigerant fluid 3 fluidically connected to the tubes of the first set 5A, of the tubes of the first set 5A, of the first collecting chamber 40 of the second manifold 4 fluidically connected to the tubes of the first set 5A, of the fluid outlet portion 301 of the first collecting chamber 30 of the first refrigerant fluid collector 3 fluidly connected to the tubes of the first assembly 5A and of the first fluid outlet channel 70.
- a first refrigerant circuit 50A consisting of the first fluid inlet channel 60 of the connection device 68, of the fluid inlet portion 300 of the first collecting chamber 30 of the first collector refrigerant fluid 3 fluidically connected to the tubes of the first set 5A, of the tubes of the first set 5A, of the first collecting chamber 40 of the second manifold 4 fluidically connected to the tubes of the first set 5A, of the
- the heat exchanger 1 also comprises at least one second refrigerant circuit 50B consisting of the second fluid inlet channel 61 of the connection device 68, of the fluid inlet portion 310 of the second collecting chamber 31 of the first coolant manifold 3 fluidically connected to the tubes of the second set 5B, of the tubes of the second set 5B, of the second collecting chamber 41 of the second coolant manifold 4 fluidically connected to the tubes of the second set 5B, of the outlet portion of fluid 311 from the second collecting chamber 31 of the first fluid collector 3 fluidically connected to the tubes of the second set 5B and of the second fluid outlet channel 71.
- the second refrigerant fluid circuit 50B corresponds to a circulation of the refrigerant fluid from the fluid inlet pipe 6 arranged in the connection device 68.
- the refrigerant fluid circulates through the second inlet channel 61 then, via tubes of the second set 5B which are arranged opposite of the second face 92 of the sealed partition 9, from the inlet portion 310 of the second collecting chamber 31 of the first manifold 3 as far as the second collecting chamber 41 of the second refrigerant fluid manifold 4.
- the refrigerant fluid then circulates in the tubes of the second set 5B arranged opposite the first face 91 of the sealed partition 9 to be routed to the outlet portion 311 of the second collecting chamber 31 of the first refrigerant fluid collector 3, where it passes through the second fluid outlet channel 71 to join the fluid outlet duct 7.
- the refrigerant is intended to exchange calories with an air flow passing through the heat exchange surface.
- the temperature of the refrigerant when it enters the heat exchanger is different from its temperature when it leaves this exchanger, and in particular the temperature decreases between the inlet and the outlet when the heat exchanger operates in evaporator mode .
- the cross circulation as it has just been mentioned makes it possible to circulate side by side a portion of refrigerant fluid close to an inlet portion, and therefore at a first temperature value, and a portion of refrigerant fluid close to 'an outlet portion, and therefore at a second temperature value.
- the heat exchanger 1 also comprises at least one second refrigerant circuit 50B consisting of the second fluid inlet channel 61 of the connection device 68, of the fluid inlet portion 310 of the second collecting chamber 31 of the first coolant manifold 3 fluidically connected to the tubes of the second set 5B, of the tubes of the second set 5B, of the first collecting chamber 40 of the second coolant manifold 4 fluidically connected to the tubes of the second set 5B, of the outlet portion of fluid 311 from the second collecting chamber 31 of the first fluid collector 3 fluidly connected to the tubes of the second set 5B and the second fluid outlet channel 71.
- the coolant takes the first coolant circuit 50A
- the coolant is routed to the heat exchanger 1 via the fluid inlet pipe 6 arranged in the connection device 68. It circulates in the first inlet channel 60 then through the tubes of the first set 5A which are arranged opposite the first face 91 of the sealed partition 9, from the inlet portion 300 of the first collecting chamber 30 of the first refrigerant fluid collector 3 to the second collecting chamber 41 of the second refrigerant fluid collector 4. It then takes the tubes of the first set 5A which are arranged opposite the second face 92 of the sealed partition 9 in order to reach the outlet portion 301 of the first collecting chamber 30 of the first refrigerant fluid collector 3, where it passes through the first fluid outlet channel 70 to reach the fluid outlet duct 7.
- the second refrigerant fluid circuit 50B corresponds to a circulation of the refrigerant fluid from the fluid inlet pipe 6 arranged in the connection device 68.
- the refrigerant fluid circulates through the second inlet channel 61 then, via tubes of the second set 5B which are arranged opposite the second face 92 of the sealed partition 9, from the inlet portion 310 of the second collecting chamber 31 of the first collector 3 to the first collecting chamber 40 of the second collector of refrigerant fluid 4.
- the refrigerant fluid then circulates in the tubes of the second set 5B arranged facing the first face 91 of the sealed partition 9 to be routed to the outlet portion 311 of the second collecting chamber 31 of the first manifold refrigerant fluid 3, where it passes through the second fluid outlet channel 71 to join the fluid outlet conduit 7.
- the present invention thus proposes a heat exchanger included in a refrigerant loop, which is intended to limit the formation of frost on this heat exchanger while having a reduced size, with tubes of two sets which are stacked in the same plane of the heat exchange surface, collectors which comprise several collecting chambers aligned in the extension of this plane of the heat exchange surface, and a connection device arranged in the extension of the collecting chambers and of the surface of heat exchange.
- the present invention cannot however be limited to the means and configurations described and illustrated here and it also extends to any equivalent means and configuration as well as to any technically effective combination of such means.
