Problems solved by technology

[0004] The main problems in the above-mentioned existing gravity heat pipe vacuum processing method are: (1) after the medium is injected into the metal tube, the heating or refrigeration treatment will consume a lot of energy (mainly electric energy), which is not conducive to energy saving
(2) The heating evaporation method relies on observing the amount of exhausted steam to evaluate the amount of medium in the remaining metal tubes, and it is impossible to accurately determine the amount of medium in the metal tubes. In addition, it is difficult to achieve the same heating temperature for each metal tube in the same batch, which leads to the same The amount of medium in the batch of products is not uniform

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.

Abstract

The invention discloses normal-temperature vacuum exhaust machining equipment of a gravity heat pipe. The equipment comprises a sealing joint, a quantitative conveying device and a seal pressing device, wherein the sealing joint is connected with a vacuum pump through an air extracting pipeline; a first electromagnetic valve is arranged on the air extracting pipeline; the quantitative conveying device is used for conveying a quantitative heat conducting medium into a metal pipe, and a liquid conveying pipeline thereof is connected with a position, near the sealing joint, of the air extracting pipeline; and the seal pressing device is suitable for closing an opening end of the metal pipe after the injection of the heat conducting medium in the metal pipe, and is near the sealing joint. When the machining equipment is used for machining the gravity heat pipe, the machining can be performed under normal temperature, so that the heating or refrigerating treatment is not needed after the injection of the heat conducting medium, and the energy consumption in the machining process is effectively reduced; and meanwhile, the quantitative conveying device is arranged for precisely controlling the medium injection quantity in the injection of the heat conducting medium in the metal pipe, and guarantees the medium injection quantity to be equal in the same batch of products, so that the product pass percent and the consistency of the products in the same batch are guaranteed.

Description

technical field [0001] The invention relates to a gravity heat pipe normal temperature vacuum exhaust processing equipment, which belongs to the technical field of solar gravity heat pipe processing. Background technique [0002] The widely used solar gravity heat pipe is processed by the thermal exhaust vacuum method. The specific method is to pre-inject the heat-conducting medium into the metal tube with one end open (which is the processing base material of the gravity heat pipe), and then place the metal tube vertically (open end) upward) to the heating platform and heated until the heat transfer medium boils, and the medium steam is discharged from the opening of the metal tube. After part of the medium steam is discharged, the open end of the metal tube is closed to form a finished gravity heat pipe. After the medium steam in the metal tube is cooled, the pressure inside the tube The decline forms a certain negative pressure environment, which plays a role in the phase...
