Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hybrid vehicles have complex and heavy cooling systems with separate circuits for engine cooling, electrical equipment cooling, and air conditioning, leading to increased size, weight, and power consumption, as well as difficulties in optimizing control and collision safety.
Innovation Solution
A cooling system that uses a single integral radiator to cool both the engine and electrical equipment, with a water-cooled condenser integrated within the radiator, and an air-cooled condenser in series, allowing for coordinated operation with the air conditioner, and featuring an intercooler that can be turned on or off based on driving mode, reducing the need for long connection pipes and optimizing coolant distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate cooling circuits are used for engine cooling, electrical equipment cooling, and air conditioning, then each means can be independently controlled, but the cooling module becomes complex and increases in size and weight
Solution Approach 1:
The patent combines the engine radiator and electrical equipment radiator into a single integrated radiator structure with separate cooling channels. This merging reduces the number of separate cooling modules while maintaining independent control capabilities through separate coolant circulation paths and control valves for each cooling circuit.
Solution Approach 2:
The integrated radiator serves multiple functions simultaneously: it cools the engine, cools electrical equipment (motor and power components), and provides heat exchange for the air conditioning system through the condenser. This multi-functional design reduces the overall number of cooling components needed in the system.
2Ease of operation
If separate cooling circuits are used for engine cooling, electrical equipment cooling, and air conditioning, then each means can be independently controlled, but the weight and size of the cooling module increase
Solution Approach 1:
The patent combines the engine radiator and electrical equipment radiator into a single integrated radiator structure with separate cooling channels. This merging reduces the number of separate cooling modules while maintaining independent control capabilities through separate coolant circulation paths and control valves for each cooling circuit.
Solution Approach 2:
The air conditioning condenser is integrated within or adjacent to the radiator structure, allowing the condenser to utilize the same air flow and space as the radiator. This nesting arrangement reduces the overall size and weight of the cooling module while maintaining separate functional circuits.
3Stability of the object's composition
If connection pipes are lengthened to prevent interference with other components, then component placement is improved, but resistance occurs due to increased movement distance of operation fluids
Solution Approach 1:
The patent combines the engine radiator and electrical equipment radiator into a single integrated radiator structure with separate cooling channels. This merging reduces the number of separate cooling modules while maintaining independent control capabilities through separate coolant circulation paths and control valves for each cooling circuit.
Solution Approach 2:
The integrated radiator acts as a central hub that receives coolant from both the engine and electrical equipment simultaneously. This intermediary structure allows for optimized pipe routing and reduced total pipe length compared to separate cooling modules, thereby reducing flow resistance while maintaining proper component spacing.
4Reliability
If the weight and size of the cooling module increase, then cooling capacity is improved, but sufficient collision space at the front side of the vehicle cannot be secured
Solution Approach 1:
The patent combines the engine radiator and electrical equipment radiator into a single integrated radiator structure with separate cooling channels. This merging reduces the number of separate cooling modules while maintaining independent control capabilities through separate coolant circulation paths and control valves for each cooling circuit.
Solution Approach 2:
The air conditioning condenser is integrated within or adjacent to the radiator structure, allowing the condenser to utilize the same air flow and space as the radiator. This nesting arrangement reduces the overall size and weight of the cooling module while maintaining separate functional circuits and adequate collision space.
