Spring-Based Thermal Pipe Mounting for EV Battery Cooling
Here’s PatSnap Eureka !
Summary
Problems
Existing thermal regulation devices for electric vehicle batteries face issues with spring misalignment and reduced thrust force due to the length of the spring, leading to inefficient heat exchange and battery temperature regulation, which affects the reliability and performance of the vehicle.
Innovation solutions
A tube support system with a transversely arcuate spring and a base that includes lugs and beads to ensure precise positioning and controlled deformation of the spring, maintaining effective contact between the heat exchanger tubes and the battery cells, optimizing the thrust force distribution.

Specific contradictions:
General conflict description:
Principle concept:
If a long spring (200-500 mm) is used to push the heat exchanger tubes against the battery, then the thermal contact between tubes and batteries is improved, but the thrust force is reduced at each end of the spring due to its length
Why choose this principle:
The spring is divided into multiple segments or sections along its length, with intermediate support points provided by the base structure. This segmentation allows the spring to maintain better thrust force distribution by reducing the effective unsupported length, while still achieving the required overall compression to ensure thermal contact between tubes and batteries.
Principle concept:
If a long spring (200-500 mm) is used to push the heat exchanger tubes against the battery, then the thermal contact between tubes and batteries is improved, but the thrust force is reduced at each end of the spring due to its length
Why choose this principle:
The base structure acts as an intermediary element that provides intermediate support to the long spring. By introducing these intermediate support points through the base, the system maintains the benefits of a long spring (thermal contact) while mitigating the disadvantage of reduced thrust force at the ends.

Abstract
The invention relates to a pipe mounting 4, intended for keeping a fluid-circulation pipe 3 urged against a vehicle battery in order to control the temperature thereof, the pipe mounting 4 including a base 5 and a spring 6 which extend longitudinally and are assembled with one another by an assembly means, characterised in that the assembly means includes at least two supports between the base 5 and the spring 6 configured to limit a transverse mobility of the spring 6 relative to the base 5, the assembly means being configured to generate a force for straightening the spring 6.
