Aluminum-extruded type thermal plate and manufacturing method thereof

Abstract

The invention provides an aluminum-extruded type thermal plate. The thermal plate comprises an aluminum-extruded base plate and horizontal flow channels. The aluminum-extruded base plate comprises a first closed end, a second closed end and a plurality of longitudinal partition plates, wherein the longitudinal partition plates are positioned between the first closed end and the second closed end and are arranged in a spaced manner in the horizontal direction; and a plurality of mutually-independent longitudinal flow channels are formed among the longitudinal partition plates. The horizontal flow channels are positioned between the first closed end and the second closed end and communicate with the longitudinal flow channels in a way of penetrating through the longitudinal partition plates;and each horizontal flow channel is internally provided with a capillary structure. By adopting the aluminum-extruded type thermal plate and a manufacturing method thereof provided by the invention,the horizontal flow channels communicating with the longitudinal flow channels are formed between the two ends of the aluminum-extruded base plate, and each horizontal flow channel is provided with the capillary structure, so the horizontal heat transfer efficiency of the aluminum-extruded thermal plate can be greatly improved, and thus the overall heat transfer effect is improved.

Description

【Technical field】 [0001] The present invention relates to a heat conducting plate, in particular to an aluminum extruded heat plate and a manufacturing method thereof. 【Background technique】 [0002] With the advancement of science and technology, electronic products are constantly developing in the direction of thinner, lighter and higher performance. However, the shrinking size of electronic products and the increase in computing speed are accompanied by continuously rising operating temperatures. Due to the small size, light weight and large heat transfer of the thermal conductive plate, currently electronic products generally adopt the thermal conductive plate for heat dissipation. The heat guide plate is basically a closed cavity containing a working fluid. After being heated, the internal working fluid will continue to undergo a liquid-vapor two-phase change cycle, so that heat energy can be transferred quickly to achieve the effect and purpose of heat conduction.

Problems solved by technology

However, due to the directionality of the extrusion process, the multiple channels inside the aluminum extruded heat plate are independent of each other and extend in the same direction, resulting in poor heat conduction efficiency in other directions and affecting the heat conduction effect of the aluminum extruded heat plate
