The client is working on the development of a next-generation automobile component. The temperature of gas flowing inside the component is higher than the conventional system, and the client is facing a challenge that the heat is dissipated to the outside of the component. The higher the temperature, the higher heat dissipation through radiation. Hence, reduction of heat radiation is essential to successfully implement the next-generation component.
A possible approach is to fill the air-based thermal insulation layer with a thermal insulation material into or onto the component. However, such a method usually involves a complicated process, which is a hurdle toward the commercialization. On the other hand, developments of thermal insulation technologies against heat radiation or other types of heat dissipation have been active in various fields, and there may exist technologies that may help overcoming the hurdle. Thus, the client has decided to publicly request the technology from those various fields.
Metal component to be processed
The metal component has a dual-wall structure as in the following schematic figure.
Figure. Sectional view of metal component
- Distance between the metal walls, which acts as thermal insulation layer: 5 mm
- Diameter of the inner wall: Approx. 220 mm
- Metal component material: Heat-resistant metal such as casted or stainless steel
The actual component does not have a circular-shape but a complex-shape. The thermal insulation between the inner and the outer walls is based on the air in-between the walls, which prevents the heat of the high temperature (700 to 1100°C) gas-flow inside the component from dissipating outside of the component. Hence, the client seeks solutions minimizing the heat dissipation toward outside of the component.
One point to note is that, according to past testing, the dominant factor of the heat dissipations in the current design is radiative heat transfer between the inner and outer walls.
Anticipated Project Phases or Project Plan
Respondents should submit proposals using the attached Response Template (click here to download template).
The client will review submitted proposals and possibly ask clarifying questions before selecting the most suitable candidates for collaboration. The client will select the best candidate(s) through evaluations. During the selection process, the client may execute non-disclosure agreements (NDA) with selected respondent(s), seek further information disclosure, and discuss specific development targets or potential opportunities.
The client will execute necessary agreement(s) with the selected respondent(s) and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.
