DETAILED DESCRIPTION

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and convenience of description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Numerous modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0022] like Figure 1-5 As shown, the technical solution of the present invention provides a cooling system for a vacuum welding furnace 1, comprising an air intake module and an exhaust module located outside the vacuum welding furnace 1 and in communication with the vacuum welding furnace 1, and a flow guide assembly located within the cavity of the vacuum welding furnace 1. In this solution, cooling gas is introduced into the vacuum welding furnace 1 through the air intake module to cool the furnace. The flow guide assembly guides the air flow within the furnace, dispersing the air flow within the furnace and increasing the contact area with the module to be cooled, thereby achieving rapid cooling of the module to be cooled and improving production capacity.

[0023] Several air inlets 2 are evenly arranged on both sides of the vacuum welding furnace 1, and the air inlets 2 extend into the cavity of the vacuum welding furnace 1. The outlet end of the air inlet 2 is located below the guide assembly and the contact plate 8; the guide assembly includes a guide plate 1 9 and a guide plate 2 10. The gas flows to the upper cavity of the vacuum welding furnace 1 through the guide gap 11 between the guide plate 1 9 and the contact plate 8, and flows out of the vacuum welding furnace 1 through the guide channel between the guide plate 1 9 and the guide plate 2 10.

[0024] The air intake module includes an air intake pipe 3 connected to the air intake port 2 and a flow rate regulating valve 4 disposed on the air intake pipe 3. Cooling gas enters the vacuum welding furnace 1 through the air intake pipe 3. The air intake ports 2 are dispersed to ensure uniform air intake within the furnace. The flow rate regulating valve 4 can regulate the amount of air intake. The incoming gas is located in the lower cavity. As it spreads upward, it passes through the heating module 16 and the contact plate 8 to cool it. At the same time, the cooling gas also enters the upper cavity through the guide gap 11 between the contact plate 8 and the guide plate 1 9 to cool the product. After flowing through the upper cavity, it flows out of the vacuum cavity through the guide channel between the guide plate 1 9 and the guide plate 2 10, and is then discharged through the exhaust assembly.

[0025] The guide plate 1 (9) is circumferentially arranged within the vacuum welding furnace 1. The guide plate 1 (9) is hollow, and the contact plate 8 is located within the hollow portion of the guide plate 1 (9). The guide plate 1 (9) is provided with a guide groove 12. Guide pipes 13 are also provided at the four corners of the guide plate, extending from the guide grooves 12 to the exterior of the vacuum welding furnace 1. The guide plate 1 (9) is generally rectangular in shape and primarily serves to guide the gas flowing out of the guide plate 2 (10) and transport it outside the vacuum welding furnace 1.

[0026] The second guide plate 10 is semi-enclosed and positioned above the first guide plate 9. A horizontal guide plate 14 is positioned at the bottom of the second guide plate 10, facing the guide groove 12. Several guide holes 15 are provided on the horizontal guide plate 14. Cooling gas enters the upper cavity opening, passes through the guide holes 15 into the guide groove 12, and then flows out of the guide pipe 13 into the exhaust assembly for discharge. This gas circulation process cools the furnace interior.

[0027] The exhaust module includes an exhaust pipe 5 connected to the guide pipe 13, and a solenoid valve 6 and a blower 7 installed on the exhaust pipe 5. The gas flowing out of the guide pipe 13 on the guide plate 9 reaches the exhaust pipe 5, passes through the solenoid valve 6, and is discharged into the exhaust pipe through the blower 7.

[0028] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
