Efficient Vehicle Temperature Control for Stability and Performance
Here’s PatSnap Eureka !
Summary
Problems
The challenge is to effectively regulate and control the temperature of in-vehicle control units in vehicles, particularly in intelligent driving systems, where high loads and varying environmental conditions can lead to instability and efficiency issues due to excessive heat or cold.
Innovation solutions
A vehicle temperature control system is introduced, featuring temperature control flow paths that pass through the in-vehicle control unit, a heat exchange unit, and a control valve system allowing for parallel or series connections to manage temperature control fluid flow efficiently, ensuring stability and performance across different conditions.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a separate temperature control system is provided for each passenger seat, then temperature control precision for each passenger is improved, but device complexity and cost increase
Why choose this principle:
The patent applies universality by enabling a single temperature control system to serve multiple passenger seats simultaneously. The system uses a plurality of blowers that can be independently controlled to direct conditioned air to different zones, allowing one system to perform the function of multiple separate systems while reducing overall complexity and cost.
Principle concept:
If a separate temperature control system is provided for each passenger seat, then temperature control precision for each passenger is improved, but device complexity and cost increase
Why choose this principle:
The patent applies segmentation by dividing the temperature control system into multiple independently controllable zones or regions. Each bler is responsible for a specific seating area, allowing independent temperature regulation for different passengers without requiring completely separate systems. This segmentation enables precise local control while sharing common infrastructure.

Abstract
Embodiments of this application provide a vehicle temperature control system, including: an in-vehicle control unit temperature control flow path, configured to perform temperature control for an in-vehicle control unit, where the in-vehicle control unit temperature control flow path flows through temperature control branches to perform temperature control on the in-vehicle control unit, there are two or more temperature control branches, and at least one temperature control branch passes through the inside of the in-vehicle control unit; a battery temperature control flow path, configured to perform temperature control for a plurality of battery units, where the battery temperature control flow path is shunted to a plurality of parallel branches to respectively perform temperature control on the plurality of battery units, and each parallel branch corresponds to one battery unit; a heat exchange unit, including an output port and a backflow port, and configured to provide temperature control fluid for the in-vehicle control unit temperature control flow path and the battery temperature control flow path; and a control valve unit, configured to control the in-vehicle control unit temperature control flow path and the battery temperature control flow path to be connected in parallel or series. By using the vehicle temperature control system, an arrangement of the temperature control flow paths can be optimized, and temperature control efficiency of the in-vehicle control unit and battery can be improved.
