Definitions
- the present invention relates to the field of refrigerant loops intended for the circulation of a refrigerant fluid and applied to a heating, ventilation and/or air conditioning installation for a motor vehicle, and relates more particularly to a heat exchanger arranged on the front face of the vehicle and forming part of such refrigerant fluid loops.
- An electric or hybrid vehicle has a refrigerant loop in order to vary the temperature inside its passenger compartment, and in particular to heat it in winter and to cool it in summer.
- the temperature of the passenger compartment is modified in particular by means of the refrigerant fluid circulating in the refrigerant fluid loop, the latter passing through a heating, ventilation and/or air conditioning installation so that a heat exchange takes place. operates with an air flow intended to be sent to the passenger compartment of the vehicle.
- the refrigerant fluid loop also includes a heat exchanger located in contact with the ambient air, on the front of the vehicle.
- the coolant circulating in the coolant loop absorbs or releases calories at the heat exchanger according to the heating or cooling needs of the passenger compartment.
- the heat exchanger located on the front of the vehicle enables the exchange of calories between the coolant which circulates in tubes arranged one above the other and spaced from one another by spacers, and a flow of air, coming from from outside the vehicle and passing through said heat exchanger between the tubes at the spacers.
- the present invention makes it possible to circumvent such a problem by proposing a heat exchanger for a refrigerant loop, comprising a heat exchange surface with a plurality of tubes extending from a longitudinal end of the heat exchange surface to another, each of the tubes being configured to form part of at least a first refrigerant fluid circuit or a second refrigerant fluid circuit through which the same refrigerant fluid passes, characterized in that at least two refrigerant fluid collectors are arranged at each of the longitudinal ends of the heat exchange surface so that two of these refrigerant fluid collectors are connected to the first refrigerant circuit and two others of these refrigerant fluid collectors are connected to the second refrigerant circuit .
- the heat exchanger can for example be installed at a front face of the vehicle, so that the heat exchange surface is installed across the air flow in order to promote heat exchange.
- the heat exchange surface is formed by the tubes constituting the heat exchanger, extending along a dimension of main elongation from one longitudinal end to the other of the heat exchange surface, and within which the refrigerant circulates.
- the tubes can in particular be stacked on top of each other so as to form a single row of tubes stacked in a stacking direction perpendicular to the main elongation dimension of said tubes.
- the stacking of the tubes is such that an air passage is provided so that the heat exchange surface can be crossed by an air flow.
- the first refrigerant circuit and the second refrigerant circuit are part of the refrigerant loop.
- the tubes of the heat exchanger each form part of one of the refrigerant circuits.
- the refrigerant loop is divided into several refrigerant circuits, which are respectively formed by collectors and part of the plurality of tubes of the heat exchanger.
- a refrigerant fluid circuit comprises two refrigerant fluid collectors intended respectively to distribute, in the tubes of the exchange surface, the portion of the refrigerant fluid flow associated with this circuit and to collect this same portion of the fluid flow refrigerant flowing through these tubes.
- the heat exchanger according to the invention comprises as many pairs of coolant manifolds as there are coolant circuits formed within the heat exchanger.
- the tubes can be connected to each of the pairs of connectors, namely an input connector and an associated output connector, so as to form an alternation in the row of tubes with tubes associated with the first separate refrigerant circuit which are interposed between tubes associated with the second refrigerant circuit.
- the same number of coolant collectors is arranged at each of the longitudinal ends of the heat exchange surface.
- the coolant fluid supply may for example correspond to a branch of the coolant fluid loop which is divided into the plurality of coolant fluid circuits before entering the heat exchanger.
- the refrigerant fluid circuits come together at a point of convergence corresponding to the evacuation of the refrigerant fluid.
- each of the coolant fluid inlet manifolds is arranged at a first longitudinal end of the heat exchange surface, each of the coolant fluid outlet manifolds being arranged at a second longitudinal end of the heat exchange surface.
- the refrigerant circulates within all the tubes of the heat exchange surface in the same direction of circulation.
- each longitudinal end of the heat exchange surface comprises at least one coolant fluid inlet manifold and at least one coolant fluid outlet manifold.
- the coolant inlet manifolds have between them the same passage section and/or the coolant outlet manifolds have between them the same passage section.
- a passage section of identical or substantially identical size makes it possible to fluidify the circulation of the refrigerant fluid of each of the refrigerant fluid circuits.
- the refrigerant fluid manifolds arranged at the same longitudinal end are aligned with each other relative to the others in a direction parallel to the main dimension of elongation of the tubes.
- the coolant manifolds arranged at the same longitudinal end are aligned relative to each other in a direction perpendicular to the main dimension of elongation of the tubes.
- the coolant manifolds arranged at the same longitudinal end are arranged between them in a concentric manner.
- the coolant manifolds have a cylindrical shape, the coolant fluid manifolds arranged at the same longitudinal end being arranged together in a reduced space by the complementarity of the respective shapes of the manifolds.
- Sections of cylindrical shapes can be various, for example circular, semi-circular or polygonal.
- the coolant fluid manifolds may have an identical cylindrical section and be arranged head to tail one by one. relation to the other. There complementarity of form of the cylindrical forms thus favors the reduction of the mechanical bulk of the heat exchanger.
- FIG. 1 represents the heat exchanger according to the invention in which a refrigerant fluid circulates according to an alternating circulation
- the invention aims to organize the circulation of the refrigerant fluid within the exchange surface of the heat exchanger .
- the refrigerant fluid manifolds 5 ensure a fluidic connection between the tubes 4 and a refrigerant fluid loop of which the heat exchanger 1 forms part.
- the heat exchanger 1 according to the invention is configured so as to comprise twice as many refrigerant fluid manifolds 5 that there are no refrigerant circuits circulating within the heat exchanger 1.
- the heat exchanger i illustrated comprises four refrigerant fluid collectors 5, arranged so that there are two refrigerant fluid collectors 5 at each end of the heat exchange surface 3 , and two refrigerant circuits are thus formed within the heat exchanger 1.
- each coolant manifold 5 located at the same longitudinal end of the heat exchange surface 3 is fluidly connected to half of the tubes 4 constituting the surface of heat exchange, the collectors connected to the same tubes participating in forming one of the circuits previously mentioned.
- the heat exchanger is such that, considering the vertical direction V, the refrigerant fluid collectors 5 of the same longitudinal end of the heat exchange surface 3 are connected to the tubes 4 alternately.
- Such an alternate arrangement of the tubes 4 and the corresponding circuits is advantageous for better homogenizing the temperature of the components of the heat exchanger when the refrigerant fluid circulates within the various circuits formed in the heat exchange surface.
- the two refrigerant fluid inlet manifolds 6 are arranged at opposite longitudinal ends with respect to each other and are each fluidly connected to one half of the tubes 4 constituting the heat exchange surface. 3, as can be seen in FIG. 1, a first half of the tubes being connected to a first inlet manifold forming part of the first refrigerant circuit 8 and a second half of the tubes being connected to a second inlet manifold forming part of the second refrigerant circuit 8.
