Motor Drive Heatsink Thermal Coupling for Temperature Uniformity

The patent merges the heatsinks of multiple motor drive devices into a unified thermal management system. Specifically, the heatsink of a first motor drive device and the heatsink of a second motor drive device are connected through a connection part to form an integrated heatsink system, allowing thermal coupling between devices with different power consumption levels. This merging enables heat redistribution from high-power to low-power devices, resolving the temperature uniformity issue while maintaining dense packing.

The connection part serves as a thermal intermediary between the heatsinks of different motor drive devices. This intermediary component facilitates heat conduction from heatsinks with higher temperature (typically from devices with higher power consumption) to heatsinks with lower temperature (from devices with lower power consumption), thereby equalizing temperatures across the system without requiring changes to the motor drive devices themselves.

The patent segments the thermal management system into modular heatsinks that can be independently designed and manufactured for each motor drive device, yet these segmented heatsinks are thermally coupled through the connection part. This segmentation allows for device independence and ease of replacement while the thermal connection enables combined heat dissipation capacity, effectively resolving the contradiction between modularity and thermal performance.

While maintaining the physical separation and independence of individual heatsinks, the patent merges their thermal functions by connecting them through the connection part. This merging of thermal pathways allows the heatsinks to function as a unified heat dissipation system, increasing overall heat dissipation capacity while preserving the modular structure and device independence.

The connection part acts as a thermal mediator that compensates for the temperature differences caused by varying power consumption. By providing a thermal conduction pathway between heatsinks, it enables heat transfer from devices operating at high power (generating more heat) to devices operating at low power, thereby equalizing temperatures and ensuring uniform service life across all electronic elements regardless of operational conditions.

The patent converts the harmful effect of temperature differences (caused by varying power consumption) into a beneficial thermal redistribution mechanism. The heat generated by devices with high power consumption, which would normally cause overheating and reduced service life, is redirected through the connection part to devices with lower power consumption, transforming the temperature imbalance problem into a self-regulating thermal equilibrium system.
