Embodiment 1
[0024] A kind of gravity heat pipe normal temperature exhaust vacuum processing equipment, such as figure 1 As shown, it includes a sealing interface 1, a quantitative delivery device and a pressure sealing device. The sealing interface 1 is connected to a vacuum pump 3 through an air suction line 2. The sealing interface 1 is suitable for connecting with a metal pipe (one end of which is open and the other end is open. closed, according to figure 2 The steps shown are to process metal tubes. The specific steps are as follows: the first step is to prepare a metal tube, usually a copper tube; the second step is to neck one end of the metal tube to form an open end; the third step is to weld a condensation head on the other end of the metal tube ), the opening end of the air pumping line 2 is provided with a first electromagnetic valve 11; It is connected at a position close to the sealing interface 1; the sealing pressure device is arranged adjacent to the sealing interface 1...
Embodiment 2
[0030] This embodiment is basically the same as Embodiment 1, except that the quantitative delivery device in this embodiment is a quantitative injector, which is used to control the amount of heat-conducting medium injected, with high precision and simplicity.
Embodiment 3
[0032] This embodiment is basically the same as Embodiment 1, the difference is that the number of the sealing interface 1 is two (in practice, it can also be set to more than two), and the air extraction pipeline 2 of each sealing interface 1 is provided with There is an air check valve 13, which can realize multi-station synchronous processing, and the air check valve 13 is set to prevent the air leakage of a single station from affecting other stations.
