Abstract


The integration technology of heat pipe packaging systems refers to the final process of heat pipe manufacturing which deside the heat pipe rate of finished products and quality. It realized the working procedure automation of pumping、heating、working substance supplies and refilling and so on besides of sealing. It also maximize avoided the unsteadiness by manual operation and ensure the uniformity and fineness of various types of heat pipe manufacturing quality.so it is a key research and development direction in the filed of heat pipe manufacturing.In order to develop a kind of new type integrated heat pipe packaging systems which uses of phase-change deaeration device and pure water working substance .This paper carried out the following main research work.1、Completed the main structural design and installation of an innovative heat pipe packaging systems. The main innovation is to escape insoluble gas in the working substance by heating and cooling process repeatedly in the phase-change deaeration device. So the working subatance in heat pipe is high-purity.2、Completed the program designing and debugging.This program uses the RS-232、RS-485and PCI to display the vacuum degree from three vacuum gauge tube of packaging systems and the temperature from two temperature transducer where lie in phase-change deaeration device.3、Construction of controlling system based on the S7-200 222 PLC and writing control program and achieve automatic control of all the packaging process.4、The following main task:build a precision working weighing measurement systemdevelop heat pipe sealed deviceestablish host-guest architecture between the host computer monitor system and PLC control system.writing interrupt program to realize the control between the host computer and PLC.
