Problem Statement
- Generally, a heat exchanger is a device that transfer heat from one medium to another (i.e. fluid to fluid), and applicable in space heating, refrigeration/air conditioning, power stations, chemical plants, petrochemical plants/petroleum refineries, natural-gas processing, and sewage treatment, etc.
- Further, the heat exchangers are designed in such a manner for better performance but suffers due to induce turbulence other associated issues. Moreover, optimized heat exchangers are complex structure and costlier to manufacture including other factors.
- Prior art systems fail in high thermal loads within the limited space including other issues.
- Hence, it is a need to mitigate above challenges & provide efficient solution.
Technology
- Present invention describes a gyroid tube structure for fluid-to-fluid heat exchange applications.
- Said structure consists of interconnected unit cells arranged in three dimensions.
- Each unit cell includes at least one first channel and at least second channel, separated by a partition wall structure.
- The partition wall structure is formed based on a periodic curved surface, specifically a periodic minimal curved surface.
- Multiple instances of the structure can be stacked to create a heat exchanger and ventilation device.
- First & second channels are perpendicular to each other, and the periodic minimal curved surface is a triply periodic minimal curved surface.
- Said Design allows for efficient heat exchange between fluids flowing through the channels.
Key Features / Value Proposition
Technical Perspective:
- Facilitates a Gyroid tube structure, specifically a periodic minimal curved surface, allowing for efficient fluid-to-fluid heat exchange.
- A triply periodic minimal curved surface (TPMS) is a surface created with the least amount of area while having a fixe boundary curve.
- The structure is in the form of a cuboid and/or cylindrical shape & is repeated and stacked one after another to form a heat exchangers & ventilation device.
Industrial Perspective:
- Provide a structure for a heat exchanger & ventilation applications.
- Facilitates higher heat transfer surface area.
- Facilitates compact structure including lightweight.
- Provides higher turbulence production.
User Perspective:
- Ensures more reliable & user-friendly apparatus for fluid –to-fluid heat transfer.
- Induce internal mixing within each fluid stream so that to promote heat transfer.
