Outer Panel-Mediated Cooling System for Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outer panel-mediated heat exchanger systems in transportation machines face challenges such as increased size and complexity due to the need for filters and humidity/pressure regulation, with limited choices for cooling targets since they primarily use air as the circulating fluid.
Innovation Solution
An outer panel-mediated cooling system that uses a cooled gas from heat exchange with external air via an outer panel, where the cooled gas does not circulate inside the machine, allowing any gas or liquid to be used as the heat medium, thereby increasing the variety of cooling targets and eliminating the need for filters and humidity/pressure regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooled gas is circulated in the interior of the transportation machine, then cooling effect is achieved, but system size increases and complexity increases due to need for filters and humidity/pressure regulation
Solution Approach 1:
The invention extracts the cooled gas from the interior circulation system and directs it externally through discharge openings. The cooling function is maintained while the problematic circulation components (filters, humidity regulators, pressure controllers) are eliminated by not circulating gas inside the cabin.
Solution Approach 2:
The cooled gas acts as an intermediary cooling medium that transfers thermal energy externally. Instead of directly cooling the cabin interior with circulated gas, the system uses the cooled gas in external heat exchange pathways, mediating the cooling effect without introducing complexity inside the cabin.
2Adaptability or versatility
If air is used as the circulating fluid, then cooling function is provided, but variety of cooling targets is limited
Solution Approach 1:
The system enables multiple fluid types (gases and liquids) to be used as cooling media through the external circulation pathway. Different fluids can be selected based on specific cooling requirements, making the system universal and adaptable to various cooling targets including electronics, batteries, and cabin air conditioning.

AI summary
An outer panel-mediated cooling system includes: an outer shell including an outer panel, an inner panel located inward of the outer panel, and a heat-insulating layer located between the outer and inner panels; a cooling chamber that is located between the outer and inner panels and in which a gas releases heat outside through the outer panel and is thus cooled; a circulation loop in which a heat medium circulates, the circulation loop including a heating section located inward of the inner panel to heat the heat medium and a cooling section located in the cooling chamber to cool the heat medium; a flow path-forming structure located in the cooling chamber to form a circulation path for the gas; and a fan located in the cooling chamber to exert a drive force on the gas to allow the gas to circulate in the circulation path.
