- Such an exchanger allows good heat exchange at the Peltier cells and a good flow distribution.
- said exchanger comprises two Peltier effect modules arranged substantially in V and said first circuit is shaped so that said first fluid coming from said battery arrives between the branches of the V and separates into two streams which each pass through one of said branches.
- Such an exchanger allows significant space saving. Indeed it allows to house the entire cooling system according to the invention under the rear floor of a vehicle, with a short overhang.
- V also allows a fast feeding Peltier effect modules in order to meet the thermal performance, compared to a series connection. It also allows a good distribution or homogeneity of the air flows on all the modules.
- this form
- V constitutes a natural flow guide cone, which avoids having convergents as well as large entry cones.
- the tip of the V formed by said Peltier effect modules is oriented towards said battery which allows good efficiency with a minimum space requirement.
- this arrangement makes it possible to reduce the return distance of the cooled air flow towards the battery.
- the air flows in said second countercurrent circuit of said first fluid.
- the battery may be disposed between the wheels of said vehicle and said exchanger may then be disposed behind said battery, for example, under the rear trunk of the vehicle.
- the disposition of said second circuit is not limited according to the invention.
- the second circuit may have an inlet disposed at a first wheel well and an outlet disposed at a second wheel well opposite said first passage. All the cooling means are then concentrated at the rear of the vehicle.
- FIG. 1 shows a schematic sectional view of the underside of the vehicle according to the invention, in a plane parallel to the underside of the battery;
- FIG. 3 shows a sectional view along a plane parallel to the lower face of the battery of the exchanger, at the hot loop;
- FIG. 4 shows a sectional view along the axis IV-IV of the exchanger cooling means
- - Figure 5 shows a sectional view of the exchanger, in a plane parallel to the underside of the battery, at the cold loop; and - Figure 6 shows a bottom view of the rear of the vehicle and cooling means.
- the vehicle of the invention comprises a battery 1 disposed under the passenger compartment, between the wheels 4.
- the rear edge 1 1 of the battery 1 is located in front of the rear wheels 4.
- the battery 1 has longitudinal channels 14 and transverse channels 15 which form a cooling network in which can circulate air to cool the battery 1.
- a system battery cooling 1 comprises an exchanger 3 which comprises at least one Peltier effect module which will be more fully described later, a first so-called “cold loop” circuit 5 and a second so-called "hot loop” circuit 7.
- the cold loop 5 connects the two longitudinal channels 14 located on the opposite sides of the battery 1 and passes through the heat exchanger 3.
- the cold loop 5 has an inlet 51 and an outlet 52, located at the rear edge 1 1 of the battery 1.
- the cold loop 5 comprises first means 53 for circulating the air contained therein. These first circulation means 53 may be a fan. They are arranged at the outlet of the exchanger 3.
- the cold loop 5 and the channel network of the battery 1 form a closed circuit.
- the coolant is air but any other fluid can be used because it circulates in a closed circuit.
- the hot loop 7 has an inlet 71 located at a rear wheel arch and an outlet 72 disposed at the opposite rear wheel arch.
- the hot loop 7 passes through the exchanger 3 and comprises second moving means 73 which are located upstream of the exchanger 3.
- the outside air to the vehicle is sucked into the inlet 71 by the second means of implementation.
- 73 passes through the heat exchanger 3 where it heats, and exits at the outlet 72, outside the vehicle.
- FIG. 2 schematically shows the cold loop 5, the hot loop 7 and the exchanger 3 and the direction of air flow in each of the circuits.
- the exchanger 3 comprises two modules Peltier effect 310. These two modules are arranged in V, the tip of the V facing the battery 1, the length of each module extending along the length of a branch of V.
- the hot flow leaving the battery 1 through the inlet 51 is sucked by the fan 53 which is disposed at the spaced ends of the branches of the V.
- the hot flow from the battery 1 is divided into two fluxes which each pass through a Peltier effect module 310.
- the two streams then collect, beyond the tip of the V, into a single cooled stream which is sent into the battery 1 by the outlet 52.
- the air outside the vehicle is sucked through the inlet 71 by the fan 73 which is disposed close to the spaced branches of the V formed by the two Peltier effect modules 310.
- the hot loop pipes 7 are arranged in such a way as to that the external air flow arrives at the tip of the V formed by the Peltier effect modules, is divided into two streams which each pass through a module 310. The two streams are then combined into one and the same flow beyond the branches separated from the V. The flow exits through the outlet 72 on the outside of the vehicle. The flows of the cold loop 5 and the hot loop 7 therefore circulate against the current.
- the inlet 71 is provided with an air filter 710 while the outlet 72 is provided with a shutter 720 which prevents the entry of water.

- Each pipe 76 is open at a module 310 and arranged so that the flow of air passing through it comes into contact with a Peltier effect cell layer 31 1.
- the flow of air entering the exchanger 3 through the pipe 76 passes on the cell layer 31 1.
- the flow passes under a layer of cells 31 1.
- the flow of the cold loop 5 flows in the space between the two cell layers 31 1, in each of the modules 310.
- the fan 73 draws air from four lines 76 arranged in two groups of two superimposed pipes according to the height of the vehicle (the height of the latter).
- the two superimposed groups of conduits 76 are arranged in a V-shape.
