Transformer Radiator Plate Layout for Gap-Free Core Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transformers with radiator plates face heat radiation performance decline due to gaps caused by manufacturing tolerances and thermal expansion differences between the core and radiator plates, leading to inefficient heat transfer.
Innovation Solution
The transformer design features different radiator plates covering the first and third surfaces of the core, ensuring close contact even with deviations in distance due to manufacturing tolerances and thermal expansion, eliminating gaps and enhancing heat radiation performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If one radiator plate covers three successively adjoining surfaces of the core, then the heat radiation coverage is improved, but gaps occur between the radiator plate and the core due to manufacturing tolerances and thermal expansion differences
Solution Approach 1:
The radiator plate is divided into multiple separate radiator plates, each covering different surfaces of the core. Specifically, first and third surfaces (opposite to each other) are covered by different radiator plates, allowing each plate to be independently positioned and contacted with the core, thereby eliminating gaps caused by attempting to cover opposite surfaces with a single rigid plate.
2Manufacturing precision
If the distance between first and third surfaces deviates due to manufacturing tolerances and thermal expansion, then contact precision is maintained with separate radiator plates, but device complexity increases
Solution Approach 1:
Each radiator plate is designed to cover multiple surfaces of the core. For example, a radiator plate covers both the first surface and the second surface (adjoining the first surface), allowing a single plate to serve multiple functions and reduce the total number of plates needed while maintaining contact precision.

AI summary
A transformer includes: a coil: a core enclosing the coil, the core including a first surface, a second surface adjoining the first surface, and a third surface opposite to the first surface and adjoining the second surface; and a plurality of radiator plates each of which covers a part of the core. The first and third surfaces are covered by different radiator plates of the plurality of radiator plates. Preferably, the core further includes a fourth surface opposite to the second surface and adjoining the third surface, and the second and fourth surfaces are covered by different radiator plates of the plurality of radiator plates.
