Description

Technical Field

[0001] The utility model discloses a rapid cooling device, belongs to the technical field of vacuum brazing process, and specifically relates to a rapid cooling device used for U150 vacuum brazing. Background Art

[0002] In the existing vacuum brazing process, the anode is heated by medium frequency, and the heat is transferred to the welding surface. When the heat reaches the melting point of the high-temperature solder, the solder melts and flows naturally, and the solder fills the welding surface, and the brazing is completed. After the brazing is completed, there will be a cooling process. Because the anode body is large and is in a vacuum state, the cooling will be very slow. It takes 5 hours to cool down to the state where the parts can be taken out, so the efficiency of brazing is very poor. Utility Model Content

[0003] Purpose of the utility model: to provide a rapid cooling device for U150 vacuum brazing, to solve the problems mentioned above in the existing technology that there is no cooling water strong cooling device after the brazing is completed, and it relies entirely on natural cooling, which has slow cooling and low working efficiency.

[0004] Technical solution: A rapid cooling device for U150 vacuum brazing, comprising: a box body, the interior of which forms a water cooling chamber; a leak-proof cover, fixedly installed on the top of the box body by bolts; a water inlet pipe and a water outlet pipe, one end of which are fixedly installed on the bottom of the box body and connected to the water cooling chamber;

[0005] The outer side of the box body is provided with a mounting ear; the other ends of the water inlet pipe and the water outlet pipe are both provided with a barb head.

[0006] In a further embodiment, a partition is provided inside the water cooling chamber to divide the water cooling chamber into a water inlet chamber and a water outlet chamber, the water inlet pipe is connected to the water inlet chamber, and the water outlet pipe is connected to the water outlet chamber.

[0007] In a further embodiment, a connecting groove is opened on the partition plate to connect the water inlet chamber and the water outlet chamber.

[0008] In a further embodiment, an anode mounting hole is provided on the partition, and the anode mounting hole passes through the box body and the anti-leakage cover.

[0009] In a further embodiment, the box body is installed in the brazing vacuum chamber through the mounting ears, the water inlet pipe and the water outlet pipe are installed to the outside of the vacuum chamber through a sealing device, and the cooling water and high-pressure air are connected by using a barb head.

[0010] Beneficial effect: The utility model is to install a cold water shortage device in the vacuum chamber in direct contact with the anode, and turn off the cooling water during brazing to ensure that there is enough heat to melt the solder. When the brazing is completed, the cooling water is passed, and the heat of the anode is quickly taken away by the cooling water, which speeds up the cooling speed and shortens the cooling time, thereby achieving the effect of improving efficiency.

[0016] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] A rapid cooling device for U150 vacuum brazing, comprising: a box body 9, the interior of the box body 9 forms a water cooling chamber 2; a leak-proof cover 1, fixedly installed on the top of the box body 9 by bolts; a water inlet pipe 4 and a water outlet pipe 6, one end of which are fixedly installed on the bottom of the box body 9 and communicated with the water cooling chamber 2;

[0020] The outer side of the box body 9 is provided with a mounting ear 3; the other ends of the water inlet pipe 4 and the water outlet pipe 6 are both provided with a barb head 5.

[0021] In one embodiment, Figures 1 to 4 As shown, a partition is provided inside the water cooling chamber 2 to divide the water cooling chamber 2 into a water inlet chamber and a water outlet chamber. The water inlet pipe 4 is connected to the water inlet chamber, and the water outlet pipe 6 is connected to the water outlet chamber.

[0022] In one embodiment, Figures 1 to 4 As shown, a connecting groove is opened on the partition plate to connect the water inlet chamber and the water outlet chamber.

[0023] In one embodiment, Figures 1 to 4 As shown, the partition is provided with an anode mounting hole 8, and the anode mounting hole 8 passes through the box body 9 and the anti-leakage cover 1.

[0024] In one embodiment, Figures 1 to 4 As shown, the box body 9 is installed in the brazing vacuum chamber through the mounting ears 3, the water inlet pipe 4 and the water outlet pipe 6 are installed outside the vacuum chamber through a sealing device, and the cooling water and high-pressure air are connected by using the barb head 5.

[0025] Working principle: install the water and air circulation cooling chamber into the brazing vacuum chamber through the installation ear 3, install the water inlet pipe 4 and the water outlet pipe 6 to the outside of the vacuum chamber through the sealing device, and use the barb head 5 to connect the cooling water and high-pressure air. During brazing, install the anode to the anode mounting hole 8 through screws, and then close the vacuum chamber for vacuum treatment. When the vacuum requirement is met, perform medium-frequency heating. When the temperature starts to drop after brazing, inject cooling water into the water inlet pipe 4 and enter the water cooling chamber 2. The cooling water enters the water outlet chamber through the connecting groove from the water inlet chamber and flows out from the water outlet pipe 6. In this way, the heat is continuously taken away by the cooling water, which plays a role in strong cooling. Finally, after taking the parts, turn off the cooling water and turn on the high-pressure air to blow away the water in the pipe to prevent the water in the cooling chamber from being vaporized and damaging the equipment due to excessive heat during the next heating process.

[0026] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
