Electric Radiator Peripheral Circuit for Even Heat Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electrical radiators for heating rooms face issues with uneven thermal power distribution, prolonged transient to steady operating conditions, and inability to handle high powers and specific loads due to inadequate natural circulation of thermal power.
Innovation Solution
A radiator design featuring a peripheral circuit ring with headers and ducts arranged externally to emitters, facilitating a high-rate natural circulation of thermal fluid, which quickly removes thermal power from the electrical resistance and ensures even distribution across the radiator surface, allowing for higher loads and faster stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional emitters are connected directly to headers with calibrated passages, then the structure is simple, but the thermal power distribution is uneven and the transient to steady state is prolonged
Solution Approach 1:
The patent segments the thermal carrier fluid circulation path by introducing a peripheral circuit ring that separates the main circulation loop from the emitter connections. This allows the thermal carrier fluid to follow a defined peripheral path (through ducts 13 and 14) before distributing to emitters, improving thermal power distribution efficiency while maintaining manufacturing simplicity through modular components.
Solution Approach 2:
The patent introduces ducts 13 and 14 as intermediary elements between the headers and the external environment/emitters. These ducts serve as mediators that guide the thermal carrier fluid along a peripheral circuit ring, enabling better thermal distribution across the radiator surface without complicating the core header-emitter connection structure.
2Productivity
If a peripheral circuit ring with ducts is added, then thermal power distribution becomes even and faster, but the device complexity increases
Solution Approach 1:
The patent merges the circuit ring structure with the existing header system by integrating ducts 13 and 14 as extensions of the headers. The peripheral circuit ring is formed by combining the headers, ducts, and emitter connections into a unified circulation path, which improves thermal distribution without requiring completely separate additional components.
Solution Approach 2:
The patent creates an equipotential thermal distribution by ensuring the thermal carrier fluid circulates through a balanced peripheral circuit ring. The ducts are dimensioned and arranged to provide equal resistance and flow characteristics, allowing uniform thermal power distribution across all emitters while maintaining a relatively simple circuit topology.
3Power
If higher electrical powers are used, then heating capacity increases, but the natural circulation becomes inadequate to remove thermal power efficiently
Solution Approach 1:
The patent applies hydraulic principles to the thermal carrier fluid circulation by designing a peripheral circuit ring with optimized duct dimensions and configurations. This hydraulic design ensures adequate flow rates and pressure gradients to efficiently remove high thermal powers generated by increased electrical heating capacity, maintaining effective natural circulation even at higher power levels.
Solution Approach 2:
The patent changes the circulation path parameters by introducing the peripheral circuit ring with specific duct geometries (ducts 13 and 14). This modifies the flow characteristics, resistance distribution, and thermal exchange efficiency of the system, enabling it to handle higher electrical powers while maintaining effective thermal power removal through natural circulation.
