Aluminum flat heat pipe automatic degassing and liquid filling packaging tool and process method thereof

Abstract

The invention discloses an aluminum flat heat pipe automatic degassing and liquid filling packaging tool and a process method thereof. The method is characterized by comprising the steps of placing aflat heat pipe on a working table, and limiting a liquid filling port of the flat heat pipe; conducting vacuum extraction on the flat heat pipe through a vacuum pump through a sealing quick joint matched with the liquid filling port of the flat heat pipe, and filling refrigerant fluid; stopping filling of the refrigerant fluid and conducting primary pressing sealing through a combination module; conducting secondary ultrasonic welding sealing through the combination module; conducting hold-down cutoff on a process pipe at the end of the liquid filing port of the flat heat pipe through the combination module; and opening the sealing quick joint and removing the process pipe. Through the method, vacuum extraction, liquid filling, sealing welding, pipe cutoff and other steps are completed inthe same working position at a time; the vacuum degree and the refrigerant filling amount are stable and controllable; the phenomenon of refrigerant leakage is avoided; the refrigerant filling amountin a sealed workpiece remains constant, and automatic production and large-scale application are realized.

Description

technical field [0001] The invention relates to radiator heat pipe manufacturing technology, in particular to an aluminum flat heat pipe automatic degassing liquid filling packaging tool and a process method thereof. Background technique [0002] Flat plate heat pipes are widely used in various heat exchange devices due to their high-efficiency thermal conductivity, variability of heat flux density, excellent isothermality, reversibility of heat flow direction, and structural adaptability, especially in the baseband of 5G base stations. The heat dissipation of components such as processing units, centralized units, and distributed units has been widely used. The flat heat pipe has a flat plate shape, and its shape is very conducive to thermal diffusion of concentrated heat sources. It has become a hot research topic in the heat dissipation of electronic components. The improvement of structure and processing method, parameter optimization, internal flow and heat transfer, c...

Problems solved by technology

[0003] In the existing technology, the mechanical pre-sealing cannot be completely sealed, and the refrigerant will naturally leak to varying degrees during the pipe cutting and artificial argon arc welding sealing process of the workpiece, which seriously affects the stability of the refrigerant charge.

In some cases, even the amount of refrigerant charged inside the sealed workpiece cannot be detected, causing a great quality hidden danger
