Abstract
The method for manufacturing products having a metal surface by imparting microfeatures onto the metal surface. The method if further described as the steps of: creating a transfer tool from a microstructured intermediate fabricated from a microstructured prototype having microfeatures; and, transferring the microfeatures to said metal surface using the transfer tool.
Claims34
A method for manufacturing a product having a metal surface comprising the steps of:
- fabricating a microstructured prototype having microfeatures selected from a set of predefined patterns of microstructures;
- creating a microstructured intermediate from said microstructured prototype so that a negative of said microfeatures are transferred to said microstructured intermediate;
- creating a transfer tool having said microfeatures from said microstructured intermediate;
- and,
- transferring said microfeatures to said metal surface by performing the steps from the group consisting of:
- rolling, stamping, casting, embossing or imprinting said microfeatures to said metal surface using said transfer tool so that a negative of said microfeatures are imprinted on the metal surface of said product so that said metal surface includes microstructures.
A method for manufacturing a product having a metal surface for use in the manufacture of a heat exchanger with a heat exchanger surface having microstructures comprising the steps of:
- fabricating a microstructured prototype having microfeatures selected from a set of predefined patterns of microstructures;
- creating a microstructured intermediate from said microstructured prototype so that a negative of said microfeatures are transferred to said microstructured intermediate;
- creating a transfer tool having said microfeatures from said microstructured intermediate;
- transferring said microfeatures to said metal surface by performing the steps from the group consisting of:
- rolling, stamping, casting, embossing or imprinting said microfeatures to said metal surface using said transfer tool so that a negative of said microfeatures are imprinted on the surface of said metal surface;
- and,
- manufacturing a heat exchanger using said product.
