Combine Controller Layout Using Cooling Device Heat and Dust Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combine designs face challenges in protecting the electric controller from both heat generated by the engine and dust accumulation, leading to potential electrical issues due to its proximity to the reaping unit.
Innovation Solution
The electric controller is strategically positioned on the side surface of a cooling device, which includes a cooling fan, and is arranged between the cooling device and the grain tank, with the cooling device supported by a frame, thereby reducing exposure to engine heat and dust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the electric controller is arranged on the front side of the shielding member to protect it from engine heat, then thermal damage risk is reduced, but the controller becomes susceptible to dust accumulation from the reaping unit
Solution Approach 1:
The patent repositions the electric controller from the front side to the rear side of the shielding member, utilizing the previously underutilized rear space. This spatial reconfiguration in the front-rear dimension simultaneously achieves thermal protection (the shielding member blocks engine heat) and dust protection (the rear position is away from the reaping unit's dust generation zone), resolving the contradiction between these two harmful factors.
2Reliability
If the electric controller is positioned away from the engine to reduce heat exposure, then thermal stability is improved, but the controller may be exposed to dust from the reaping unit
Solution Approach 1:
The shielding member serves as an intermediary structure that provides thermal protection to the electric controller. By positioning the controller on the rear side of this shielding member, the system achieves thermal stability while the shielding member itself acts as a barrier that also prevents dust from reaching the controller, thus resolving the contradiction through the intermediary's dual protective function.
3Device complexity
If the electric controller is arranged in the vicinity of the reaping unit for compact design, then space utilization is improved, but dust accumulation on connection portions increases
Solution Approach 1:
The patent extracts the electric controller from the dust-prone front region and relocates it to the rear region of the shielding member. This separation removes the controller from the harmful dust environment generated by the reaping unit while maintaining compact overall design, as the rear space of the shielding member is utilized for this purpose. The connection portion is thereby protected from dust accumulation.
