Solution Overview
Problem
Conventional cooling structures for electric components in vehicles require a cooling apparatus, increasing manufacturing costs and space requirements, while also exposing passengers to heat from these components.
Innovation Solution
A heat insulating structure that eliminates the need for a cooling apparatus by using a fixing member, a cover member, and a heat insulating member to improve heat dissipation and protect passengers from heat without increasing manufacturing costs, featuring a configuration where the electric component is placed on a fixing bracket above the floor panel, covered by a cover member, and insulated by a heat insulating bracket that directs heat away from passengers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling apparatus is installed to cool electric components, then heat dissipation performance is improved, but manufacturing cost increases
Solution Approach 1:
The invention extracts and eliminates the cooling apparatus from the system by using the battery case's own structure (insulating layer and air cooling passages) to achieve heat dissipation, thereby removing the need for separate cooling equipment and reducing manufacturing costs
Solution Approach 2:
The battery case is designed to serve multiple functions: it provides structural support, thermal insulation through an insulating layer, and heat dissipation through integrated air cooling passages, eliminating the need for dedicated cooling apparatus
2Temperature
If a cooling apparatus is installed to cool electric components, then heat dissipation performance is improved, but device complexity increases
Solution Approach 1:
The invention merges the heat dissipation function into the battery case structure itself by integrating air cooling passages and an insulating layer, combining multiple functions (support, insulation, cooling) into a single component and reducing overall system complexity
Solution Approach 2:
The cooling apparatus is extracted and removed from the system, replacing it with a simplified structure that uses the battery case's own design features to achieve heat dissipation without additional complex components
3Volume of moving object
If electric component is placed close to floor panel, then space utilization is improved, but passengers are affected by heat
Solution Approach 1:
The battery case is segmented into functional layers including an insulating layer that divides the space between the electric component and the floor panel, creating thermal barriers that prevent heat from reaching passengers while maintaining compact spacing
Solution Approach 2:
The insulating layer acts as an intermediary between the hot electric component and the floor panel/passenger space, blocking heat transmission while allowing the electric component to be positioned close to the floor panel for efficient space utilization

[Problem to be Solved] To provide a heat insulating structure of an electric component capable of eliminating the need for a cooling apparatus, improving heat dissipation performance of the electric component and preventing passengers from being affected by heat while preventing an increase in the manufacturing cost. [Solution] A heat insulating structure of an electric component (22) includes: a fixing bracket (21) including a placement surface (21a) on which the electric component (22) is mounted, the fixing bracket (21) being installed on an upper surface of a floor panel (2) of a vehicle (1); a cover member (23); and a heat insulating bracket (41). The cover member (23) includes a rib (23S), a rib (23T) and a rib (23U). The rib (23S) is provided on a ceiling wall (23A) and is in contact with a right end portion (41b) of a ceiling wall (41A) in a direction in which the ceiling wall (41A) extends. The rib (23S) is provided on a rear wall (23C) facing the rear wall (41B) and is in contact with a right end portion (41c) of a rear wall (41B). The rib (23U) is provided on the rear wall (23C) and is in contact with a bottom end portion (41a) orthogonal to a direction in which the rear wall (41B) extends.
