The multi-row radiator with a controlled flow of heating medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-row heating radiators lack effective control over the flow ratio of the heating medium among individual plates, leading to reduced heating output and increased production costs due to complex valve systems and complications in cleaning.
Innovation Solution
The implementation of inflow and outflow fittings with integral filling cores and composite material interfaces, featuring axially movable cylinders or rotary valves with throttling elements, allows for independent control of heating medium flow between heating plates, enabling precise regulation of heating output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heating plates are hydraulically interconnected to ensure uniform heat distribution, then heating coverage is improved, but flow control flexibility deteriorates
Solution Approach 1:
The heating system is divided into hydraulically independent heating plates, each with its own flow control. The segmentation allows independent regulation of flow to each plate while maintaining overall system functionality, resolving the contradiction between uniform heat distribution and flow control flexibility.
Solution Approach 2:
Dynamic flow control is introduced through adjustable flow distribution screens and throttling elements that can be modified during operation. This allows the system to adapt flow distribution to different heating requirements while maintaining hydraulic independence between plates.
2Measurement precision
If complex valve systems are used to control flow ratio among heating plates, then flow control precision is improved, but device complexity and production costs worsen
Solution Approach 1:
Complex external valve systems are removed and replaced with integrated flow control elements directly incorporated into the heating plate structure. The flow distribution screens and throttling elements are built into the plate design, simplifying the overall system while maintaining precise flow control capability.
Solution Approach 2:
Flow control functions are merged with the heating plate structure itself. The flow distribution screens, throttling elements, and heating channels are integrated into a single compact design, eliminating separate valve assemblies and reducing device complexity while preserving flow control precision.
3Measurement precision
If complex valve systems are used to control flow ratio, then flow control precision is improved, but production costs and maintenance difficulty worsen
Solution Approach 1:
The heating radiator is segmented into independent heating plate modules that can be manufactured separately and assembled. This modular approach simplifies production, reduces costs, and enables precise flow control through integrated screens and throttling elements in each module.
Solution Approach 2:
Flow control is achieved by changing the geometric parameters of integrated flow distribution screens and throttling elements rather than using complex mechanical valves. This approach simplifies manufacturing while maintaining precise flow regulation capability.
4Reliability
If heating medium flows symmetrically through all heating plates, then uniform heat distribution is improved, but heating efficiency deteriorates
Solution Approach 1:
Different heating plates are provided with different flow distribution characteristics through locally adapted flow distribution screens and throttling elements. This allows optimization of heat distribution in different zones while maintaining high overall heating efficiency, resolving the contradiction between uniformity and efficiency.
