Preparation method of multiple-channel aluminum flat plate heat pipe provided with fiber bundle liquid absorbing core structure

Abstract

The invention discloses a preparation method of a multiple-channel aluminum flat plate heat pipe provided with a fiber bundle liquid absorbing core structure. The method comprises the steps that fiber bundle liquid absorbing cores are led into multiple-channel aluminum flat plate channels, and through leveling, flattening, fastening, pressing, sealing and working liquid pouring, the high-capillary-rate ultra-thin multiple-channel aluminum flat plate heat pipe with the thickness being 1-2 mm is obtained. According to the preparation method of the multiple-channel aluminum flat plate heat pipe provided with the fiber bundle liquid absorbing core structure, the difficulty that the fiber bundle liquid absorbing cores are led into an ultra-thin heat pipe cavity is effectively lowered, and the ultra-thin aluminum flat plate heat pipe can be obtained through flattening of an aluminum flat plate heat pipe performing body; the fiber bundle liquid absorbing cores which are fastened, pressed and tightly attached to the inner walls of the channels by positioning bosses inside the channels have pretty high capillary limitation, can greatly enhance the conveying capacity of aluminum flat plate heat pipe working liquid and increase the conveying speed of the aluminum flat plate heat pipe working liquid, improves antigravity heat transfer performance of the aluminum flat plate heat pipe and enlarges the use range of the aluminum flat plate heat pipe.

Description

technical field [0001] The invention relates to a preparation method of a multi-channel aluminum flat heat pipe, in particular to a preparation method of a multi-channel aluminum flat heat pipe with a fiber bundle liquid-absorbing core structure. Background technique [0002] With the widespread social demand of electronic equipment, the heat flux density of electronic chips has increased sharply and the effective heat dissipation space has become increasingly narrow. Flat heat pipes with high thermal conductivity, high reliability, fast thermal response, and large heat dissipation area have become the heat dissipation system for electronic components. Ideal method for optimization. In the existing flat heat pipe technology, aluminum flat heat pipes are widely used in electronic products with small spaces, especially in heat dissipation systems of LED display devices, due to their small footprint, high heat exchange efficiency and large heat dissipation area. However, the i...
