Abstract
This invention relates to a method of manufacturing an object with microchannels provides therethrough, and more particularly, but not exclusively, to a method of manufacturing a micro heat exchanger with microchannels provided therethrough. The method includes the steps of providing a metal base layer made from a first metal; forming a plurality of spaced apart ridges, made from a second metal, on the base layer; depositing more of the first metal onto the ridges in order to cover the ridges; and re moving the ridges using a chemical etching process so as to produce microchannels in a body made of the first metal.

A method of manufacturing an object with microchannels provided therethrough, the method comprising the steps of:
- providing a metal base layer made from a first metal;
- forming a plurality of spaced apart ridges, made from a second metal, on the base layer by depositing the second metal onto the base layer by way of a cold spraying process;
- depositing more of the first metal onto the ridges in order to cover the ridges;
- and
- removing the ridges using a chemical etching process so as to produce microchannels in a body made of the first metal.
