MICRO CHANNEL SOLUTIONS

Micro Channel Solutions The key to solving heat transfer issues revolves around two things, increasing the surface area and improving the efficiency in which heat is transferred. Using Micro Deformation Technology, we are able to create Microchannels in almost any ductile material, effectively increasing the surface area within a limited footprint.

Microchannels are ideal for improving heat transfer in a wide range of thermal materials including titanium, stainless steel, silver, aluminum, copper, molybdenum, and in non-metallic materials like Teflon, polyethylene, rubber and PVC.

Micro-Deformation Technology (MDT) is a patented technology with unique processing capabilities. It provides a method for producing a surface with alternating depressions and ridges via a distinctively designed tool. Although some intricate configurations can be achieved by more conventional approaches, namely photochemical etching, Wire EDM, and skiving, etc., these approaches are relatively time-consuming and costly. MDT provides design engineers a unique alternative to create new configurations and expand available materials for challenging liquid cooling applications.

In addition to processing a broad range of ductile materials, MDT process allows design engineers the ability to form different configurations on a variety of base materials with great precision and flexibility not seen before. One can vary the pitch and the depth of the micro-channels, in fin counts as large as 625 fins per inch.

The MDT process is also able to achieve capabilities greater than conventional finning techniques: raising fins on the OD of a tube much higher and greater in ridge count than the conventional finning process. This is particularly important in heat transfer efficiency where special corrosion-resistant alloys, such as Ti, must be used. By raising the ridge height, the lower heat transfer ability of alloys such as Ti and CuNi is offset and unit efficiency is maintained.
