Solution Overview
Problem
Existing oil-water heat exchangers for internal combustion engines face challenges in efficiently preheating engine oil, leading to increased pollutant emissions when the oil is not at operating temperature, and their production is complex and tailored to specific applications.
Innovation Solution
A heat exchanger system comprising an oil-water heat exchanger module with a separate layered heating module, featuring a substrate with an electrical heating coating applied to it, which is mounted externally, allowing for simple and flexible heating of fluids without direct application to the heat exchanger, thereby enabling effective preheating and upgrading existing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating device is applied directly to the heat exchanger surface, then heating effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The heating device is segmented into a separate layered module that can be manufactured independently and then assembled to the heat exchanger. This allows the heating element to be produced using simple painting processes on a separate substrate, reducing manufacturing complexity while maintaining heating effectiveness through the layered structure.
Solution Approach 2:
A substrate acts as an intermediary between the heating coating and the heat exchanger surface. The heating coating is applied to the substrate rather than directly to the heat exchanger, simplifying the manufacturing process while the substrate serves as a carrier that can be easily attached to the heat exchanger.
2Temperature
If heating coating is applied directly to heat exchanger, then heating efficiency is improved, but adaptability decreases
Solution Approach 1:
The layered heating module with substrate is designed as a universal component that can be adapted to different heat exchanger types and sizes. The substrate serves as a flexible carrier that can be manufactured in various dimensions and attached to different heat exchanger surfaces, making the heating solution universally applicable while maintaining heating efficiency.
3Loss of time
If heating device is integrated into heat exchanger, then preheating capability is improved, but production complexity increases
Solution Approach 1:
The heating coating is applied to the substrate in advance during a simple painting process, creating a pre-assembled heating module. This preliminary action allows the heating element to be ready for installation on the heat exchanger without requiring complex integration processes, thus improving preheating capability while keeping production simple.
