Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine temperature control devices for electric vehicles face challenges in efficiently cooling multiple batteries mounted at different locations, leading to increased complexity, space requirements, and reduced flexibility in vehicle mounting due to separate condensers and long, complicated piping systems.
Innovation Solution
A machine temperature control device incorporating a main condenser that integrates the condenser functions of multiple thermosiphon circuits, allowing for a single cold energy supply medium to exchange heat with working fluids across all circuits, and a sub condenser that distributes cold energy to additional circuits, reducing the number of components and simplifying the configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate thermosiphon circuits are used for each battery, then each battery can be cooled independently, but the device complexity and number of components increases
Solution Approach 1:
The patent merges multiple separate condensers into a single integrated condenser that serves multiple thermosiphon circuits. This consolidation reduces the total number of components while maintaining the ability to cool multiple batteries independently through shared condensing functionality, directly resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The integrated condenser is designed to perform multiple functions simultaneously - it serves as the condensing unit for multiple different thermosiphon circuits that cool different batteries. This multi-functional design allows one component to replace what would traditionally require multiple separate components, reducing overall system complexity while preserving independent cooling capabilities.
2Reliability
If separate condensers are used for multiple batteries, then each battery can be cooled independently, but the space requirements and vehicle mounting flexibility decreases
Solution Approach 1:
By combining multiple condenser units into a single integrated condenser, the patent significantly reduces the total space occupied by the temperature control system. This consolidated design maintains independent temperature control for each battery while occupying less vehicle space, thereby improving mounting flexibility and reducing the area constraint.
3Reliability
If multiple separate thermosiphon circuits are used, then each battery can be cooled independently, but the pipe routing complexity and design workload increases
Solution Approach 1:
The patent merges the condensing functions of multiple thermosiphon circuits into a single integrated unit, which simplifies the overall pipe routing architecture. While the evaporator circuits remain separate for independent cooling, the consolidation of condensing operations reduces the number of pipe connections and routing complexity, thereby lowering design workload and installation complexity.
