Liquid-Cooled Electrical Connector Shell Layout for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connectors face challenges in heat dissipation when used in liquid-cooled environments, particularly due to manufacturing complexities and the need for effective heat dissipation channels that are not adversely affected by metal shell joints.
Innovation Solution
The design includes an insulating body with cooling liquid circulation grooves and a metal shell with snapped outer walls, where the first outer wall portion has a larger dimension than the second, allowing for a cooling liquid circulation slot that communicates with the grooves, and the joint between the outer walls is not provided with the slot, enabling efficient heat dissipation by liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling liquid circulation slots are provided on the metal shell, then heat dissipation performance is improved, but the joint structure of the metal shell becomes more complex and difficult to manufacture
Solution Approach 1:
The metal shell is divided into multiple separate parts (first metal shell part and second metal shell part) that are assembled together. The cooling liquid circulation slots are provided on these separate parts, allowing the slots to be formed independently before assembly, thus avoiding the complexity of forming slots through a joint structure.
Solution Approach 2:
The cooling liquid circulation slots are arranged to extend in directions that avoid intersecting with the joint structure. By changing the spatial arrangement and orientation of the slots, the design allows effective heat dissipation channels to be created without complicating the joint assembly process.
2Ease of manufacture
If the metal shell is formed by stamping, bending and buckling a metal sheet, then manufacturing process is simplified, but the joints created during assembly adversely affect the arrangement of heat dissipation channels
Solution Approach 1:
The metal shell is segmented into multiple parts that are assembled through simple stamping, bending and buckling operations. Each part can be formed independently using standard metal forming processes, and the segments are then joined together, allowing heat dissipation channels to be arranged on each segment without being constrained by complex joint requirements.
Solution Approach 2:
Different regions of the metal shell parts have different functions: some regions contain cooling liquid circulation slots for heat dissipation, while other regions contain joints for assembly. This local differentiation allows each region to be optimized independently, with joints placed in locations that do not interfere with the heat dissipation channel arrangement.

Function Achieved in This Case
This configuration enhances heat dissipation performance by allowing liquid to flow through the slots and grooves, effectively removing heat generated by the electrical connector while minimizing the influence of the joint on the arrangement of the cooling channels.
Implementation Method 1
the liquid is capable of flowing through the cooling liquid circulation slot and the cooling liquid circulation groove to take away the heat generated by the electrical connector
Implementation Method 2
take away the heat generated by the electrical connector

AI summary
An electric connector includes an insulating body, a number of conductive terminals and a metal shell. The insulating body includes a mating slot and a cooling liquid circulation groove communicating with the mating slot. The metal shell includes a first outer wall portion and a second outer wall portion snapped and fixed together with the first outer wall portion. A dimension of the first outer wall portion along the second direction is larger than a dimension of the second outer wall portion along the second direction. The first outer wall portion includes a cooling liquid circulation slot communicating with the cooling liquid circulation groove. A joint of the first outer wall portion and the second outer wall portion is not provided with the cooling liquid circulation slot, thereby reducing the influence of the joint on the arrangement of the cooling liquid circulation slot. An application of the electrical connector in a liquid-cooled environment is disclosed.
