Snow Blower Heatsink Assembly for Moisture-Isolated Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow blowers face challenges in managing heat generation while preventing moisture interference, particularly affecting heat-generating elements like motors and electronics control boards, which is difficult to address while maintaining operation in cold environments.
Innovation Solution
The snow blower incorporates a heatsink with a cold-side face along the snow flow path and a hot-side face in thermal communication with heat-generating components, allowing heat dissipation through the snow flow path, keeping these components isolated from moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If increased airflow is provided to mitigate heat generation, then heat dissipation is improved, but moisture interference with heat-generating elements increases
Solution Approach 1:
The system divides the heat dissipation function into two separate pathways: a first airflow path that provides cooling air to the heatsink without exposing it to snow, and a second path that allows snow to flow past the heatsink for heat exchange without direct contact. This segmentation resolves the contradiction by enabling heat dissipation while preventing moisture interference.
Solution Approach 2:
The heatsink acts as an intermediary component between the heat-generating elements and the snow flow. It mediates heat transfer from the motor and control board to the passing snow, enabling heat dissipation while the snow itself serves as a thermal sink rather than a moisture source for the electronics.
2Object-affected harmful factors
If heat-generating elements are isolated from snow and moisture, then moisture interference is prevented, but heat dissipation becomes difficult
Solution Approach 1:
The system uses controlled airflow (pneumatics) to deliver cooling air to the heatsink and to flush the snow flow path. The airflow mechanism enables heat dissipation from isolated components while maintaining the isolation barrier against snow and moisture, resolving the contradiction between protection and cooling.
3Adaptability or versatility
If the snow blower operates in cold environments, then functionality is maintained, but heat management issues arise
Solution Approach 1:
The system converts the cold environment from a harmful factor into a beneficial thermal sink. The cold air and snow, which would normally be obstacles to heat dissipation, are utilized as heat sinks to cool the motor and control board, enabling the snow blower to operate effectively in cold temperatures without overheating.

AI summary
A snow blower includes a frame, a rotatable auger, one or more walking elements, a chute, and a heatsink. The frame may define a snow flow path. The rotatable auger may be mounted to the frame. The one or more walking elements may be mounted to the frame apart from the rotatable auger to support the snow blower. The chute may extend from the frame above the rotatable auger. The heatsink may include a cold-side face disposed along the snow flow path in fluid communication therewith and a hot-side face disposed apart from the snow flow path.
