Multi-Row Radiator Overflow Pipe for Front-Panel Load Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-row radiators with part-load functions face challenges in achieving preferred flow through the front heating panel due to thermal buoyancy, leading to inefficient heating and requiring complex valve fittings that are difficult to install correctly, resulting in connection errors.
Innovation Solution
The radiator features connection fittings in the lower corners with an overflow pipe directing the heating medium from the front panel to the rear panel, using T-pieces with blocking disks and bores to maintain flow direction, allowing for easy assembly and preventing connection errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complex valve fittings are welded in at the factory to achieve part-load function, then the heating medium can be directed to flow preferentially through the front heating plate, but the device complexity increases and installation becomes more difficult
Solution Approach 1:
The connection fittings are segmented into multiple functional components: T-pieces for flow distribution, blocking disks for flow direction control, and overflow pipes for excess flow management. This segmentation allows each component to perform a specific function, simplifying the overall system while maintaining part-load capability.
Solution Approach 2:
The flow paths are pre-configured during manufacturing with blocking disks positioned in T-pieces and overflow pipes installed. This preliminary action ensures that the part-load function is automatically achieved without requiring complex valve assemblies or post-installation configuration, reducing both device complexity and installation difficulty.
2Reliability
If blocking disks are used in T-pieces to control flow direction, then the flow direction can be maintained, but the device complexity increases
Solution Approach 1:
The blocking disks in the T-pieces automatically control the flow direction based on the heating medium's natural circulation patterns. The system self-regulates the flow distribution between front and rear heating plates without requiring external control mechanisms, maintaining reliability while minimizing added complexity.
Solution Approach 2:
Simple blocking disks made from inexpensive materials are used instead of complex valve mechanisms. These disposable-like components are easy to manufacture and install, providing reliable flow direction control without the complexity and cost of adjustable valve fittings.
3Temperature
If the heating medium flows through the front heating panel first, then the warming effect is improved, but thermal buoyancy causes the heating medium to rise and flow out through the valve into the rear panels, reducing heating efficiency
Solution Approach 1:
The overflow pipe acts as an intermediary element that captures the heating medium after it has heated the front panel and redirects it to the rear panels through a controlled path. This prevents energy loss while ensuring both panels receive adequate heating, mediating between the thermal buoyancy effect and heating efficiency requirements.
Solution Approach 2:
The blocking disks and overflow pipe configuration ensures continuous circulation of the heating medium through both front and rear panels. The heating medium flows through the front panel first, then is redirected to the rear panels, maintaining continuous useful heating action throughout the entire radiator system rather than allowing premature discharge.

Function Achieved in This Case
This design ensures efficient heating by maintaining the desired flow directions, preventing overflow, and simplifying the installation process, ensuring both panels are effectively heated and reducing the risk of connection errors.
Implementation Method 1
the heating medium immediately rises after flowing into the lower flow due to thermal buoyancy
Implementation Method 2
the overflow pipe directs the flow V of the heating medium from the heating element plate facing the room to be heated into the heating plate(s) arranged behind it

AI summary
The multiple-row heating body has a flow connection and a reverse flow connection for a heating medium of a heat distribution system. A flow permeable heating body plate is arranged opposite to the space to be heated and another flow permeable plate is arranged within the space to be heated. The lower connection fittings (c,d) are in fluidic connection with the flow connection or reverse flow connection and are connected with each other by an overflow pipe. The overflow pipe is arranged horizontally between heating plates (21).
