Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closed-loop temperature equalization systems with single-flowpath structures face challenges in efficiently transmitting thermal energy due to structural weaknesses, increased flow resistance, and lack of interfaces for observation and maintenance, especially when dealing with temperature differentiation between heat releasing surfaces and external bodies.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-flowpath structure is adopted in the heat releasing device, then the device complexity is reduced, but the thermal energy transmission efficiency deteriorates and flow resistance increases
Solution Approach 1:
The heat releasing device is divided into multiple flowpaths (first flowpath, second flowpath, third flowpath) instead of using a single flowpath. This segmentation allows heat exchange fluid to flow through multiple parallel channels, increasing the heat transfer surface area and improving thermal energy transmission efficiency while maintaining manageable device complexity through modular design.
2Length of stationary object
If the flowpath area is increased to transmit thermal energy from heat exchange fluid spaced further away, then the heat transmission distance is improved, but the structural strength deteriorates and flow resistance increases
Solution Approach 1:
Instead of using a single large flowpath area that would compromise structural strength, the device segments the flowpath into multiple smaller parallel channels. This allows the heat exchange fluid to travel longer distances through distributed flowpaths while maintaining the structural integrity of each individual flowpath and reducing overall flow resistance through parallel flow distribution.
3Device complexity
If a single-flowpath structure is used, then the device complexity is reduced, but the interfaces for observation and maintenance are reduced
Solution Approach 1:
The heat releasing device is segmented into multiple independent flowpaths with separate inlet and outlet ports. This segmentation provides multiple access points for observation and maintenance activities, allowing technicians to isolate and service individual flowpaths without shutting down the entire system, thereby improving ease of repair while maintaining reasonable device complexity through standardized modular components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively transmits thermal energy across larger distances with reduced flow resistance and provides interfaces for maintenance, improving the overall efficiency and operational reliability of thermal energy distribution.
Implementation Method 1
transmit thermal energy to a heat exchange fluid (104) as it passes through a heat gaining device (101)
Implementation Method 2
the heat exchange fluid (104) circulates in the system as a result of a cold descending/hot ascending effect
Implementation Method 3
an outwardly-expanded arc-shaped flowpath structure may be formed at one or more than one turning locations of the closed-type circulation flowpath, for temporarily storing a part of the heat exchange fluid (104) and moderating the flow speed of the heat exchange fluid (104) to reduce flow damping

AI summary
A closed-loop heat equalization system includes a heat gaining device installed within a natural thermal energy storage body, and a heat releasing device having multiple flowpaths, the heat gaining and releasing devices being connected by pipeline structures to form a closed-loop flowpath for a heat exchange fluid. An outwardly expanded arc-shaped structure may be included at one or more turning locations in the pipeline structures. The pipeline structures may include an operation port and sealing plug at a top corner of the closed-loop flowpath, and an auxiliary heating/cooling device or fluid pump controlled by a sensing device and an electric energy control unit.
