Micro-channel tubes and apparatus and method for forming micro-channel tubes
Abstract:
An apparatus and method are provided for extruding a micro-channel tube (402) from a non-aluminum metal or alloy such as copper. The micro-channel tube is formed by simultaneously extruding two rectangular shaped billets (404; 406) to form a top portion of the micro-channel tube and a bottom portion of the micro-channel tube in parallel. The top and bottom portions are then joined during the extrusion process (e.g., within a die assembly) to form the micro-channel tube (402).
Abstract(Chinese):

提供了一种用于从非铝金属或合金（例如铜）挤出微通道管（402）的装置和方法。 微通道管通过同时挤出两个矩形坯料（404; 406）而形成，以形成微通道管的顶部和微通道管的底部平行。 然后在挤出过程（例如，在模具组件内）将顶部和底部部分接合以形成微通道管（402）。
