Micro cone tower array heat exchanging plate and manufacture method thereof

The invention discloses a micro cone tower array heat exchanging plate and a manufacture method thereof and belongs to the field of heat dissipation. A multi-height micro cone tower array structure is respectively arranged on two sides of the heat exchanging plate. The structures are formed by mixing regular triangular pyramid linear arrays and regular hexagonal pyramid linear arrays with two heights or formed by mixing multi-height linear or circumference arrays of pyramids and conoids. A notch milling cutter with a V-shaped cutting tip or a diamond grinding wheel is used for milling or grinding a thin plate, a V-shaped groove array in the first direction is machined on one side of the thin plate during machining, then the thin plate rotates an angle theta sequentially to machine the rest V-shaped groove arrays respectively, and the other side of the thin plate is machined through the same method. By means of the heat exchanging plate, specific surface area of the thin plate can be increased, concave joints
