[0036] Embodiment Two

[0037] On the basis of Embodiment One, and different from Embodiment One,

[0038] A heat exchanger groove aluminum for preventing backflow further includes:

[0039] A filtering component 400, which is used to intercept impurities in the fluid flowing inside the groove aluminum body 100.

[0040] The filtering component 400 includes an intercepting mesh plate 401 fixed on the inner wall of the groove aluminum body 100 and located on the upper surface of the mounting plate 301. The intercepting mesh plate 401 is inclined on the inner wall of the groove aluminum body 100, which can quickly intercept impurities in the fluid.

[0041] The filter assembly 400 also includes a drain pipe 402 opened on the inner wall of the grooved aluminum body 100 and located at the bottom end of the interception mesh plate 401, and the outer surface of the grooved aluminum body 100 is provided with a sealing assembly 403 for sealing the drain pipe 402, so as to facilitate the discharge of impurities through the drain pipe 402.

[0042] The sealing assembly 403 includes an L-shaped plate 4031 fixed on the outer surface of the grooved aluminum body 100, and a sliding plate 4032 slidably arranged on the inner wall of the L-shaped plate 4031. A sealing plug 4033 adapted to the end of the sewage pipe 402 is fixed on the surface of the sliding plate 4032, and the sewage pipe 402 can be sealed by the sealing plug 4033.

[0043] A rectangular groove is provided on the inner top wall of the L-shaped plate 4031, and a threaded column 4034 is rotatably provided on the inner wall of the rectangular groove, and the end of the threaded column 4034 extends to the side of the L-shaped plate 4031 and is fixed with a rotating block 4035 for rotating the threaded column 4034, and the top end of the sliding plate 4032 is slidably connected to the inner wall of the rectangular groove.

[0044] A limiting rod 4036 is fixedly disposed on the inner side wall of the L-shaped plate 4031 , and a threaded hole threadedly connected to the outer surface of the threaded column 4034 and a sliding hole slidably connected to the surface of the limiting rod 4036 are respectively opened on the side surface of the sliding plate 4032 .

[0045] In this embodiment, by providing the filter assembly 400, impurities in the fluid can be intercepted under the action of the interception mesh plate 401, and the impurities can be automatically discharged.

[0046] During operation, when the fluid flows inside the groove aluminum body 100, the blocking ball 303 is driven to separate from the bottom end of the drainage tube 302 under the action of the fluid pressure and impact force, so that the fluid can flow smoothly through the drainage tube 302. At the same time, when the fluid does not flow, the blocking ball 303 can contact the bottom end of the drainage tube 302 under the action of the two springs 304, and seal the bottom end of the drainage tube 302 under the action of the sealing ring 305, thereby effectively avoiding the backflow of the fluid. In addition, the groove aluminum can block the fluid in the fluid under the action of the interception mesh plate 401. The impurities can be intercepted. When the impurities need to be discharged, the rotating block 4035 can be rotated to drive the threaded column 4034 to rotate. The rotation of the threaded column 4034 drives the sliding plate 4032 to move, thereby driving the sealing plug 4033 to disengage from the sewage pipe 402, so that the sewage pipe 402 can be opened and the impurities can be automatically discharged. After discharge, the rotating block 4035 can be rotated in the opposite direction to drive the sealing plug 4033 to enter the end of the sewage pipe 402, thereby effectively blocking the sewage pipe 402 and effectively preventing the sealing plug 4033 from falling off due to the pressure of the fluid.
