Innovation Solution
A modular heat management system is designed with a coolant heater, a first coolant pump connected to the heater's outlet, and a second coolant pump connected to a temperature control object, all housed in the engine room, with optimized piping and positioning to reduce distance between components and enhance compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of components and pipes in the coolant system is increased to achieve comprehensive cooling and heating functions, then the system can provide complete temperature control for interior air conditioning and electronic components, but the assembly process becomes complicated and difficult
Solution Approach 1:
The coolant system is divided into multiple independent loops: a first coolant loop for interior air conditioning and a second coolant loop for electronic component cooling. Each loop has its own pump and flow path, allowing independent operation and simplified assembly of each segment while maintaining comprehensive temperature control functionality
Solution Approach 2:
The coolant system is designed to serve multiple functions through a unified infrastructure: the coolant heater can heat coolant for both interior heating and electronic component heating, and the system can operate in different modes (heating mode, cooling mode, dual-mode) to accommodate various temperature control requirements across different components
2Adaptability or versatility
If the number of pipes connecting components is increased to link all coolant system components, then comprehensive cooling and heating coverage is achieved, but pressure loss increases due to longer pipe lengths
Solution Approach 1:
The coolant system is segmented into separate loops with dedicated pumps for each loop. The first coolant loop serves interior air conditioning components while the second coolant loop serves electronic components. This segmentation allows each loop to be optimized for its specific function with minimized pipe lengths, reducing overall pressure loss while maintaining comprehensive coverage
Solution Approach 2:
The coolant heater acts as an intermediary component that can serve both heating functions for different loops. By positioning the coolant heater strategically and using it as a shared component, the system achieves comprehensive heating coverage without requiring separate heating devices for each loop, thereby minimizing the number of pipes needed
3Area of stationary object
If components are positioned far apart to accommodate engine room layout, then installation space requirements are met, but noise and vibrations become difficult to manage
Solution Approach 1:
Multiple coolant system components (coolant heater, first coolant pump, second coolant pump, and associated piping) are merged into a single integrated module that can be installed as one unit in the engine room. This modular design allows the components to be positioned close to each other internally, minimizing vibration transmission, while the entire module fits within the available engine room space

AI summary
A heat management system of the present invention comprises: a coolant heater for heating coolant; a first coolant pump which is connected to a coolant inlet or a coolant outlet of the coolant heater to pump the coolant and is coupled to the coolant heater; and a second coolant pump which is connected to a battery side to pump the coolant and is coupled to the coolant heater, wherein the coolant heater, the first coolant pump, and the second coolant pump are arranged in an engine room of a vehicle. Thus, a loss of coolant pressure can be reduced in a pipe which connects components constituting a coolant system of the vehicle, such that the performance of the system is improved and noise and vibration in the interior of the vehicle may be reduced.
