Description
Technical Field
The utility model relates to an subassembly for cooling electric energy storage device.
Background
A device for pressing a heat exchanger against a battery is known from patent application US 2013309545.
A method for assembling a battery, a cooling device and a system for pressing a battery against a cooling device are also known from the patent US 8845762.
However, one disadvantage of both embodiments is that these different embodiments are dimensioned to a predetermined height, which means that they have a "spring" effect or "reaction" effect, which inhibits modularity.
Another disadvantage of some of the proposed embodiments is that the pressure system needs to bear on a flat surface in order to provide a uniform reaction force.
SUMMERY OF THE UTILITY MODEL
The present invention is particularly directed to improving at least some of the disadvantages of the prior art.
To this end, the invention relates to an assembly for cooling an electrical energy storage device, in particular a battery, the assembly comprising:
-a cooling unit comprising at least one channel through which a heat transfer fluid can be circulated in order to remove heat released by the storage device;
-a support, at least partly made of foam, on which the cooling unit is positioned.
Accordingly, the present invention helps to at least partially address some of the shortcomings of the prior art.
More specifically, the invention makes it possible to realize an assembly that does not require support on a flat surface, so that the cooling unit is pressed against the electrical energy storage device in a substantially uniform manner.
In particular, the implementation of a support made at least partially of foam makes it possible to bear on a surface that may not be flat, the profile of the support being practically adaptable.
Moreover, another advantage of such an embodiment is that the weight of the assembly is less than the weight of known cooling assemblies.
Furthermore, such a support allows a certain amount of modularity, since it is at least partly composed of foam. Indeed, such foams may be subject to relative crushing, depending on their compressibility.
Such a compression factor may be, for example, between 0.2 and 0.8.
In a particular embodiment, the support is arranged to deform when the cooling unit is located on top of it.
Thus, the support has mechanical damping advantages.
In a variant, the support at least partially surrounds the channel through which the heat transfer fluid circulates.
In an embodiment of the invention, the support member is deformed so as to provide a concave surface for receiving the channel.
In an embodiment of the invention, the surface area of the support member is at least equal to 70% of the surface area of the cooling unit.
In an embodiment of the present invention, the thickness of the supporting member is 2mm to 50 mm.
In an embodiment, the support is shaped such that its circumference substantially matches the circumference of the cooling unit.
In a variation of the invention, the foam is a viscoelastic foam.
According to a particular aspect of the invention, the foam is an insulating foam.
According to a particular aspect of the invention, the foam is a shape memory foam.
According to a particular feature of the invention, the foam at least partially constituting the support may have an elastic limit comprised between 10MPa and 100 MPa.
In a particular embodiment of the invention, the support member exerts a surface pressure distributed in an even manner on the cooling unit.
In a variant of the invention, the support member exerts a surface pressure of 1N/cm2 to 15kN/cm 2.
The foam may for example belong to the group comprising polymers, polyurethanes, polypropylene or indeed rubber.
Drawings
The invention will be better understood from the following description, provided as an illustrative and non-limiting example, and with reference to the accompanying drawings, and other details, features and advantages of the invention will become more apparent, in which:
figure 1 is a schematic perspective view of an assembly according to an embodiment of the invention; and
figure 2 is a schematic side view of an assembly according to the embodiment of figure 1.
Detailed Description
An embodiment of the invention will now be described with reference to fig. 1 and 2.
In the example shown in the figures, the invention relates to an assembly 1 for cooling an electrical energy storage device 2. In particular, the electrical energy storage device may be a battery consisting of, for example, a plurality of electrical energy storage cells (cells). The battery may also be comprised of a plurality of "pouch cells".
According to the utility model discloses, this subassembly includes:
a cooling unit 3 comprising at least one channel through which a heat transfer fluid can circulate in order to remove the heat released by the storage means 2;
a support 4, at least partially made of foam, on which support 4 the cooling unit 3 is positioned.
The cooling unit may be a unit consisting of a plurality of heat transfer fluid circulation pipes connected together by at least one collector to form a heat transfer fluid circulation loop.
These circulation pipes may be pipes including fluid circulation microtubes.
In this example, the cooling unit is at least partially constructed of aluminum.
Further, the cooling unit may include one or more pairs of fluid circulating plates.
As mentioned above, the cooling unit 3 is pressed against the electrical energy storage 2 by the support 4.
In other words, the cooling unit is positioned on the support to allow contact between the cooling unit and the electrical energy storage device.
In the claimed invention, the support 4 is at least partially made of foam.
Such a support 4 exerts a surface pressure distributed in an even manner on the cooling unit 3. As a result, the cooling unit 3 is pressed against the electrical energy storage means 2 in an optimized and uniform manner.
According to various embodiments, the support may comprise 50% to 100% foam.
More particularly, the support may comprise 50% to 75% foam.
In the example shown, the support is composed entirely of foam. This allows for maximum compression, facilitating positioning of the support in the vehicle without requiring modification, or at least overly expensive modification, due to the small amount of space occupied.
Moreover, another advantage of such an embodiment is that the weight of the assembly is less than the weight of a conventional cooling assembly.
The selection of foam may be guided by use within the desired working range. Some foams allow compressive forces close to the compressive force of a compression spring to be released, while other foams may be more "soft". Therefore, the selection of the foam must be guided by at least one of the following parameters:
-a space available for positioning a support;
-a compressive force applied to the cooling unit to ensure sufficient mechanical retention to allow heat transfer from the area to be cooled to the cooling unit;
-the level of insulation required in order to limit the heat transfer from the cooling unit to the areas that are not to be cooled;
-a vibration profile of an environment in which the assembly is located;
-the humidity level of the environment in which the assembly is located.
Depending on the desire to be guided by one of the above parameters, it is therefore possible to choose a support in which the implementation foam is at least partially composed of viscoelastic foam.
Preferably, a foam having a density of 300Kg/m3 to 600Kg/m3 and a Shore A hardness of 10 to 90 can be selected.
The insulating foam may also be selected to isolate areas that will not be cooled.
The insulating foam may be selected from the polymer series, polyurethane, polypropylene or indeed rubber.
According to a particular aspect of the invention, the foam is a shape memory foam.
One advantage of this feature is that deformation of the support is minimized by the nature of the foam.
Another advantage of realizing a support at least partly made of foam is that it keeps the cooling unit 3 against the battery 2 even in case of mechanical breakage.
In the example shown in the figures, the thickness of the support is substantially equal to 50 mm.
Of course, other embodiments are envisaged in which the thickness of the support is between 2mm and 50 mm.
The support 4, where the cooling unit 3 is located, at least partly surrounds the channel through which the heat transfer fluid circulates. Thus, the cooling of the battery 2 by the heat transfer fluid is optimized by the cooling unit 3 being pressed against the battery 2.
According to an example, the support 4 may have a surface area at least equal to 70% of the surface area of the cooling unit 3.
In the example shown in the figures, the surface area of the support 4 is substantially equal to 90% of the cooling unit 3.
Furthermore, the support 4 is shaped such that its circumference substantially matches the circumference of the cooling unit 3. This is achieved in particular by the fact that the support 4 is at least partially made of foam.
