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

VSEngineering Contradiction Analysis

1Reliability

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.

Inventive Principle:
