1Temperature
If a separate cooling system is added to cool the electronic control system, then the cooling effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent combines the electrical connection function and cooling function into a single integrated structure. The connecting structure includes a connecting section for electrical connection and a cooling section for heat dissipation, eliminating the need for separate cooling components and reducing system complexity while maintaining effective cooling of the electronic control system
Solution Approach 2:
The connecting structure serves multiple functions simultaneously: it provides electrical connection between the heating element and control component, and acts as a heat sink for cooling the electronic control system. This multi-functionality reduces the number of components needed and simplifies the overall device structure
2Ease of operation
If the control component is configured as a power switch for controlling the heating element, then the control functionality is improved, but heat generation increases
Solution Approach 1:
The patent converts the harmful heat generated by the power switch into a beneficial cooling opportunity. The connecting structure is designed to conduct away the heat generated by the control component during switching operations, transforming the problematic heat generation into a manageable thermal management issue that is resolved through the integrated cooling function
