Summary on Grant Application Form
Lattice-frame materials (LFMs) are a new development made possible by computer based design and control of numerically controlled processing. They consist of a 3-D network of struts or plates. Potnetial industrial applications include heat dissipators for the computer industry, replacements for honeycombs, impact-resistant structural panels, and low resistance filtration systems, in addition to biomedical applications in medical devices for minimally-invasive surgery and interventional cardiology. The focus of the proposed work will be on the development of highly efficient heat dissipation media for high power electronics (eg multi-chip modules). The heat dissipators will be based on convective cooling across LFMs to explore their large surface area density, subject to additional design constraints on compactness, weight, stiffness, and flow resistance. In cases of power surge (eg lightening strike), it is proposed to protect the electronic devices by imbedding phase change materials within the heat dissipation media. The project aims to make LFMs, to determine the relationships between macroscopic properties and microstructures for LFMs by combining analytical modelling with numerical simulation and epxerimental measurement, and to develop an implementation methodology that enables design engineers to select LFMs with microstructures optimised for best heat transfer performance at affordable costs.
