Solution Overview
Problem
Existing containers for electric/electronic equipment, such as frequency converters or inverters, face challenges in heat dissipation, with known methods like air fins or forced ventilation being insufficient or costly, and liquid-based cooling requiring system disassembly and increased complexity.
Innovation Solution
A container with a heat dissipator featuring a flange with a concave part that matches the external surface of a pipe, allowing for removably connected heat dissipation and fixing, using a counterflange for locking, made of materials with high heat conductivity, enabling efficient heat transfer to circulating fluid without system intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If spontaneous air circulation through fins is used for heat dissipation, then the structure is simple, but the cooling effectiveness is insufficient
Solution Approach 1:
The patent applies hydraulic cooling by circulating liquid through a heat exchange chamber instead of relying on air circulation through fins. This provides superior heat dissipation effectiveness while maintaining reasonable structural complexity, directly resolving the contradiction between simple structure and effective cooling.
2Temperature
If forced ventilation with fans is used for heat dissipation, then cooling effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces mechanical fan-based forced ventilation with a hydraulic cooling system that uses liquid circulation through a heat exchange chamber. This achieves superior cooling effectiveness without the mechanical complexity and cost of fans, motors, and associated control systems.
Solution Approach 2:
The patent substitutes the mechanical ventilation system (fans, motors) with a hydraulic system that uses fluid circulation and heat exchange principles. This replacement eliminates moving parts and mechanical complexity while maintaining or improving cooling effectiveness.
3Temperature
If liquid cooling with heat exchange chamber is used, then heat dissipation effectiveness is improved, but ease of installation and removal deteriorates
Solution Approach 1:
The patent divides the container into separable components: the main container body and a detachable heat dissipation assembly containing the heat exchange chamber. This segmentation allows the heat dissipation system to be easily installed and removed independently without dismantling the entire container or hydraulic system, resolving the contradiction between effective liquid cooling and ease of maintenance.
Solution Approach 2:
The patent extracts the heat exchange chamber as a separate, removable component that can be independently installed and removed. This extraction allows maintenance personnel to service or replace the cooling system without affecting the main container or requiring system disassembly, while still providing effective liquid cooling when installed.
4Temperature
If liquid cooling system is integrated into container, then heat dissipation effectiveness is improved, but ease of repair deteriorates
Solution Approach 1:
The patent segments the cooling system into a removable heat dissipation assembly that can be independently accessed and repaired. This segmentation allows maintenance personnel to service the heat exchange chamber and associated components without dismantling the entire container or hydraulic system, significantly improving ease of repair while maintaining effective liquid cooling.
Solution Approach 2:
The patent extracts the heat exchange chamber as a standalone component that can be removed and serviced independently. This extraction improves maintenance accessibility by allowing technicians to repair or replace cooling components without interfering with the main container or other system parts, while still providing effective heat dissipation when installed.
