Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high voltage boxes in electric devices suffer from poor heat dissipation, leading to overheating issues that compromise safety performance.
Innovation Solution
A high voltage box design featuring a relay with a conducting strip in direct contact with the lower housing, combined with a water cooling plate and heat conduction elements, enhances heat dissipation by rapidly transferring heat away from the relay to the housing and external cooling system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized design with compact structural design is used for the high voltage box, then device complexity is reduced and ease of manufacture is improved, but heat dissipation effect deteriorates leading to overheating problems
Solution Approach 1:
The high voltage box is segmented into multiple functional modules including relay module, control module, and water cooling module. Each module has dedicated heat dissipation pathways, allowing heat to be dissipated from different locations simultaneously rather than relying on a single centralized heat dissipation structure.
Solution Approach 2:
A water cooling plate is introduced as an intermediary heat dissipation medium between the relay module and the external environment. The water cooling plate absorbs heat from the relay module through thermal conduction and transfers it to the cooling water flowing through its channels, effectively mediating the heat transfer process.
2Speed
If the conducting strip is in direct contact with the lower housing, then heat dissipation speed is improved, but the risk of heat transfer to surrounding components increases
Solution Approach 1:
The lower housing is designed with localized heat dissipation structures including dedicated heat dissipation holes and water cooling plate mounting areas. The heat dissipation properties are concentrated in specific regions where heat generation occurs, rather than uniformly distributing heat dissipation capabilities throughout the entire housing structure.
Solution Approach 2:
A water cooling system is implemented using hydraulic principles. Cooling water is pumped through channels in the water cooling plate, absorbing heat from the relay module through thermal conduction. The circulating water continuously removes heat from the system, preventing heat accumulation and unintended heat transfer to surrounding components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves heat dissipation efficiency, reducing overheating risks and enhancing safety performance by effectively dissipating heat generated by the relay and other components.
Implementation Method 1
heat generated by work of the relay is transferred to the conducting strip of the relay, and since the conducting strip is in direct contact with the inner side of the lower housing, the heat in the conducting strip may be directly transferred into the lower housing and is rapidly transferred to the outside of the high voltage box via the lower housing
Implementation Method 2
the water cooling plate may absorb the heat transferred to the lower housing by components and parts, such as the relay, or the like, which may further improve the heat dissipation effect of the high voltage box
