Solution Overview
Problem
Existing dry block temperature calibrators require disassembly of the entire machine for maintenance when a single component malfunctions, increasing maintenance costs and complexity.
Innovation Solution
A modular design for the dry block temperature calibrator allows independent assembly and disassembly of the furnace body, control board assembly, and measurement board assembly, along with innovative radiator designs that enhance heat dissipation efficiency and reduce weight, enabling separate maintenance of components without affecting the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the furnace body is locked together with other parts in existing products, then the structural integrity is maintained, but the entire machine has to be disassembled for maintenance, greatly increasing maintenance cost
Solution Approach 1:
The calibrator is divided into independent modular assemblies including furnace body assembly, control board assembly, and measurement board assembly. Each assembly can be independently disassembled and maintained without affecting other parts, allowing direct access to specific components for repair while maintaining overall structural integrity through standardized connection interfaces.
2Loss of energy
If traditional heat dissipation structures are used, then the heat dissipation function is provided, but the weight is excessive and heat dissipation efficiency is insufficient
Solution Approach 1:
The radiator adopts a composite structure combining aluminum alloy material with optimized fin geometry. The aluminum alloy provides high thermal conductivity while the optimized fin structure increases heat dissipation surface area, achieving superior heat dissipation efficiency with reduced weight compared to traditional solid metal radiators.
Solution Approach 2:
The radiator design incorporates three-dimensional fin structures that extend heat dissipation surfaces in multiple directions. This dimensional expansion creates large heat dissipation area within compact volume, improving heat transfer efficiency while minimizing the addition of weight.
3Volume of moving object
If the control board assembly is positioned close to the furnace body, then the device compactness is improved, but the harsh temperature condition near the furnace body affects other components
Solution Approach 1:
The control board assembly is extracted from the high-temperature zone near the furnace body and positioned in a separate temperature-controlled compartment. This spatial separation protects sensitive electronic components from thermal damage while maintaining device compactness through optimized arrangement of separated modules.
Solution Approach 2:
Thermal insulation barriers and heat shielding structures are introduced as intermediary elements between the furnace body and control board assembly. These intermediaries block harmful thermal radiation and convection while allowing compact positioning of components, protecting electronics from excessive temperature exposure.
