Solution Overview
Problem
Existing electric vehicles lack an efficient cooling system design that effectively manages battery temperature, especially during high-performance operations, which can lead to reduced efficiency and lifespan.
Innovation Solution
The electric work vehicle incorporates a cooling structure with a fan mounted at the front, powered by an electric motor, along with a condenser, radiator, and drier, all strategically positioned to enhance airflow and heat dissipation, while being supported by a chassis and battery housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cooling structure is added to manage battery temperature, then battery temperature management is improved, but device complexity increases
Solution Approach 1:
The cooling structure integrates multiple components (condenser, radiator, drier, fan) into a unified assembly mounted on the battery housing. This merging of components resolves the contradiction by creating a compact, organized system that manages battery temperature effectively while controlling overall structural complexity through integrated design.
2Productivity
If the fan is positioned at the front of the cooling structure, then airflow efficiency is improved, but the arrangement complexity increases
Solution Approach 1:
The fan is positioned at the front of the cooling structure to preliminarily draw air through the condenser and radiator before reaching the battery housing. This preliminary action of air intake and direction optimizes airflow efficiency from the start, resolving the contradiction by establishing effective airflow patterns before air contacts the battery components.
3Area of stationary object
If the cooling structure overlaps with the battery housing in the width direction, then space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The cooling structure is designed to overlap and nest with the battery housing in the width direction, with the condenser, radiator, and drier arranged to utilize the same lateral space. This nesting arrangement resolves the contradiction by maximizing space utilization while the integrated mounting design accommodates reasonable manufacturing tolerances.
