Multi-row plate radiator comprising a heating medium and a connecting element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-row heating radiators face challenges in controlling the heating output of subsequent plates, leading to reduced overall heating performance and increased production costs due to complex overflow connections and cleaning issues.
Innovation Solution
A connecting element with a T-shaped casing and axially movable valve stem allows for regulated flow from the rear plate while maintaining continuous flow from the front plate, using conventional lateral sockets and threaded bushings to form a central spherical part with integrated outflow holes and a sealing poppet for adjustable heat output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heating medium flows equally into all heating plates, then the overall heating performance is maintained, but the heating output of subsequent plates cannot be controlled and the front plate temperature is reduced
Solution Approach 1:
The patent divides the heating system into separate flow paths for the front heating plate and subsequent heating plates. The front plate receives the full flow of heating medium through dedicated inlet ports, while subsequent plates receive flow through a separate path controlled by a regulating valve, allowing independent temperature control of each section.
Solution Approach 2:
The patent introduces a regulating valve with an axially movable stem that can dynamically adjust the flow of heating medium to subsequent heating plates. This dynamic control mechanism allows the system to adapt heating output based on thermal requirements, enabling both high front plate temperature and controllable subsequent plate heating.
2Adaptability or versatility
If overflow connections are used to control flow distribution, then heating output control is achieved, but production costs increase and cleaning becomes difficult
Solution Approach 1:
The patent extracts the flow control function from complex overflow connections and implements it through a simple regulating valve with an axially movable stem. This valve is integrated into the connecting element, eliminating the need for complicated overflow structures while achieving the same heating output control function with simpler manufacturing and maintenance.
Solution Approach 2:
The connecting element is designed to perform multiple functions: it connects heating plates, distributes heating medium, and provides flow regulation through the integrated valve. This multi-functional design eliminates the need for separate overflow connections and simplifies the overall system structure, reducing production costs and easing maintenance.
3Temperature
If a single inlet port supplies the front plate only, then the front plate temperature is increased, but the flow distribution complexity increases
Solution Approach 1:
The patent merges the flow distribution function with the connecting elements that link heating plates. The connecting elements incorporate inlet ports and a regulating valve, combining multiple functions (connection, flow distribution, and flow regulation) into single components, thereby reducing overall system complexity while maintaining effective front plate heating.
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
This solution enhances heat output control and comfort by maintaining continuous flow from the front plate while regulating the rear plates' output, reducing production costs and simplifying maintenance, and can be manufactured as a single workpiece with optional manual or motorized valve control.
Implementation Method 1
the heating medium transfers the greater part of its heat to said front heating plate, while entering, already partially cooled down, the second or subsequent heating plates
Implementation Method 2
the heating medium, which flows through this inlet port, is distributed along the upper edge of the front heating plate
Implementation Method 3
a sealing plate with a through hole, which is closable by a sealing component carrying a spindle
Implementation Method 4
the second threaded bushing to its central spherical part, whereby a common insert passes sealingly through both threaded connecting bushings
