How to choose a suitable microchannel flat tube

1. Consider channel structure and size Number and shape of channels: The number of channels in a microchannel flat tube will affect its heat transfer efficiency. Generally speaking, having a larger number of channels can increase the heat transfer area, but it may also increase fluid resistance. Common channel shapes include rectangles, ellipses, etc. Rectangular channels are relatively eas
