Technical Field

[0001] The utility model relates to the technical field of heat exchanger processing, in particular to a heat exchanger joint welding cooling device. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc. They are widely used. During the processing of heat exchangers, it is necessary to weld and cool the heat exchanger joints.

[0003] As disclosed in the Chinese patent: A welding cooling device for aluminum-silicon encapsulated shell, application number: CN202221227018.1, including a base and a casing, a conveyor line is arranged at the top of the base, the conveyor line is arranged in the inner cavity of the casing, the left and right ends of the conveyor line extend to the left and right ends of the casing respectively, a fixed box is arranged at the top of the casing, a cooling fan is arranged in the inner cavity of the fixed box, a fixed groove is opened on the left side of the inner cavity of the fixed box, the fixed frame can be slidably inserted in the inner cavity of the fixed box and extends to the fixed groove, a filter cloth is fixedly installed in the inner cavity of the fixed frame, a handle is arranged at one end of the fixed frame away from the fixed groove, and a fixing assembly for fixing the fixed frame is arranged in the inner cavity of the fixed box. The welding cooling device for aluminum-silicon encapsulated shell solves the problem that the cooling equipment after the welding of the aluminum-silicon encapsulated shell is inconvenient to filter dust when in use.

[0004] However, in the above technical solution, when cooling the welding temperature, the cooling fan is used to speed up the air flow at the welding point, thereby cooling the welding point, and filtering the dust in the air through the filter. However, with the long-term use of the device, more dust will gradually accumulate on the filter, affecting the filtering effect of the filter. At this time, the filter can only be taken out, replaced and cleaned. In the process of taking out the filter, replacing and cleaning the filter, the entire device will be in a shutdown state until the filter is cleaned and reinstalled in the device. During the shutdown period, welding cooling cannot be performed, affecting the welding cooling efficiency. Utility Model Content

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the blocking door 5 includes a blocking door base 501, a third slide groove 502 is provided on the blocking door base 501, a through groove 503 is provided on one side inner wall of the third slide groove 502, a baffle 504 is slidably provided in the third slide groove 502, a buckle groove 505 is provided on the baffle 504, a plurality of balls 506 are provided on the outer walls on both sides of the baffle 504, a positioning plug plate 507 is provided on the outer wall surface on one side below the baffle 504, and a first magnetic attraction block 508 is provided on the outer wall surface on one side below the positioning plug plate 507;

[0025] A positioning slot 509 is provided on the inner wall of one side below the third slide slot 502, and a second magnetic block 5010 is provided in the positioning slot 509. When the first filter clamp plate 6 is taken out from the first slide slot 3 or the second filter clamp plate 7 is taken out from the second slide slot 4, the first filter clamp plate 6 or the second filter clamp plate 7 no longer squeezes the baffle plate 504 in the corresponding baffle door 5. Then, under the action of gravity and the suction force between the first magnetic block 508 and the second magnetic block 5010, the baffle plate 504 moves toward the positioning slot 509, so that the positioning plug plate 507 is inserted into the positioning slot 509. Subsequently, the first magnetic block 508 and the second magnetic block 5010 fit together to fix the positioning plug plate 507 in the positioning slot 509. 503, thereby fixing the position of the baffle 504, so that the baffle 504 is used to automatically close the through slot 503 to prevent external air from entering the first slide slot 3 or the second slide slot 4 directly through the through slot 503 without being filtered by the filter 8, and then entering the device body 1 through the first slide slot 3 or the second slide slot 4. When it is necessary to reinsert the first filter clamp 6 into the first slide slot 3 or the second filter clamp 7 into the second slide slot 4, the baffle 504 is moved upward through the buckle slot 505, thereby releasing the baffle 504 from closing the through slot 503, and then the first filter clamp 6 or the second filter clamp 7 can be reinsert into the first slide slot 3 or the second slide slot 4 through the third slide slot 502 and the through slot 503.

[0026] The working principle of this heat exchanger joint welding cooling device:

[0027] During use, when the filter screen 8 on the first filter screen clamp 6 needs to be replaced or cleaned, first a new filter screen 8 is placed on the second filter screen clamp 7, and then the first filter screen clamp 6 is taken out of the first slide groove 3, and then the first filter screen clamp 6 drives the gear 11 to rotate through the first tooth groove 9, and the gear 11 makes the second filter screen clamp 7 gradually enter the second slide groove 4 through the second tooth groove 10, so that the filter screen 8 in the second filter screen clamp 7 is used to filter the air passing through the ventilation pipe 2, when the first filter screen clamp 6 is completely taken out of the first slide groove 3 for easy replacement and cleaning, the first filter screen clamp 6 no longer squeezes the baffle 504 in the corresponding baffle door 5, and then under the influence of gravity and the second filter screen clamp 6, the filter screen 8 in the second filter screen clamp 7 is removed from the first slide groove 3. Under the action of the suction force between the first magnetic block 508 and the second magnetic block 5010, the baffle 504 moves toward the positioning slot 509, so that the positioning plug plate 507 is inserted into the positioning slot 509, and then the first magnetic block 508 and the second magnetic block 5010 fit together to fix the positioning plug plate 507 in the positioning slot 509, thereby fixing the position of the baffle 504, and then the baffle 504 is used to automatically close the through slot 503, and then the air can be filtered through the ventilation pipe 2 and the air is allowed to enter the device body 1, and then the device body 1 is used for welding cooling, and the filter 8 can be replaced and cleaned without stopping the machine, thereby improving the welding cooling efficiency.
