Problems solved by technology
If the tubes of the heat exchanger twist along their length, this twist cannot be corrected by the spring and can even be exacerbated
Also, springs that connect directly to the battery make battery replacement more difficult
[0008] Furthermore, prior art thermal regulation devices fail to address the problem of thermal conduction between the different metal elements of the battery pack, which adversely affects the heat exchange between the battery and the heat exchanger, and the prior art thermal Regulators also fail to address the risk of corrosion caused by galvanic effects between different components that can lead to battery failure

Embodiment Construction
[0047] In all these figures, the same elements have the same reference numerals.
[0048] figure 1 is a schematic cross-sectional side view of the battery pack 1 . The battery pack 1 has a housing 3 containing a battery 5, usually comprising one or more energy storage cells or accumulators 7 connected in parallel or in series, to form a voltage generator with a desired capacity.
[0049] The cross section of the energy storage unit 7 may be a parallelogram. The cell 5 thus formed is a parallelepiped.
[0050] Advantageously, if the battery has multiple storage cells, such as figure 1 With three storage units shown, the heat exchanger 9 would have the same number of tubes 10 . These pipes 10 are flat multi-channel pipes connected together by manifolds 11 to enable heat transfer fluid to be transported.
[0051] Optimizing the number of pipes 10 to the number of energy storage units 7 in the battery 5 helps to minimize the weight of the heat exchanger 9 and thus the overall...

Abstract
The invention relates to a thermal regulation device for a battery pack (1) of a motor vehicle, the battery pack comprising at least one battery (5) housed in a housing (3), said thermal regulation device comprising at least one A heat exchanger (9), which is in contact with the battery (5), at least one elastic element (15), which is arranged at the bottom (14) of the casing (3) in order to hold the heat exchanger (9) against the battery (5 ). An insulator (13) is arranged between the elastic element (15) and the heat exchanger (9).
Description
technical field [0001] The present invention relates to a thermal regulation device for a battery pack of a motor vehicle, and more particularly to a thermal regulation device for a battery in a hybrid and / or electric vehicle, ensuring a good relationship between the battery and the heat exchanger heat exchange. Background technique [0002] Thermal regulation of batteries is very important, especially in the field of electric and hybrid vehicles. In fact, the temperature of the battery must be maintained between 20°C and 40°C to ensure vehicle reliability, range and performance, and to optimize the service life of the battery. [0003] In electric and hybrid vehicles, batteries typically consist of several electrical energy storage cells connected together to form a voltage generator with the required capacity. [0004] These electrical energy storage units positioned in a protective housing form a so-called battery pack. It is known to use thermal regulators in order to...
