Abstract

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 in V-shaped grooves are favorable for core forming, runners formed by the multi-height micro cone tower array structures are favorable for complicating a fluid flowing condition, and a heat transferring effect of the heat exchanging plate is improved.

Description

technical field [0001] The invention relates to heat exchange plate technology, which belongs to the field of heat dissipation, and in particular to a microcone tower array heat exchange plate and a manufacturing method thereof. Background technique [0002] With the development of technologies such as very large block integration (VLSI) circuits, electronic technology is developing rapidly in the direction of high speed, high power, and miniaturization. However, since the heat flux density per unit area of ​​microelectronic devices is getting higher and higher, and the high integration determines its small heat dissipation space, electronic technology is currently facing a major technical problem in the field of thermal control, which forces microelectronic devices to pay attention to heat dissipation technology put forward higher requirements. [0003] In 1981, Tuckerman and Pease in the United States first proposed the concept of "micro-groove radiator", which applied mi...
