Further, when the cooling liquid flows to the communicating channel 402 through the liquid inlet area 401, since the auxiliary plate two 11 is located at the liquid inlet area 401 and is close to one end of the liquid inlet pipe 2 and is rotationally connected with the plate body two 4, and the auxiliary plate two 11 is arc-shaped, the cooling liquid sequentially impacts one side of the protrusion of the auxiliary plate two 11 in the flowing process, so that the auxiliary plate two 11 swings left and right with the connection of the auxiliary plate two 11 and the plate body two 4 as an axis, and the auxiliary plate two 11 drives the cleaning block 13 located at two sides of the auxiliary plate two 11 to swing left and right when swinging, and the cleaning block 13 is attached to the inner wall of the plate body two 4 when swinging left and right, so that the cleaning block 13 scrapes off impurities and dirt adhered to the inner wall of the plate body two 4 located at the liquid inlet area 401, thereby avoiding the problems of unsmooth cooling liquid flowing and difficult cleaning of the inner part of the plate body two 4.
Then, when the coolant flows to the communicating channel 402, the communicating channel 402 is provided with the second splitter plate 14 and the spoiler column 15, the second splitter plate 14 and the spoiler column 15 are symmetrically arranged with respect to the center line of the second plate body 4, the second splitter plate 14 is arranged in a shape of "7", the second splitter plate 14 positioned near the liquid inlet area 401 directs the coolant flowing to the communicating channel 402 toward the liquid outlet area 403, the second splitter plate 14 positioned near the liquid outlet area 403 directs the coolant flowing to the communicating channel 402 toward the liquid outlet area 403, and the spoiler column 15 is positioned near the middle position of the second auxiliary plate 11 and the first splitter plate 12, so that the spoiler column 15 reduces the coolant backflow to a certain extent, referring to fig. 4. Therefore, the second flow dividing plate 14 divides the cooling liquid flowing to the communicating channel 402 again, increases the contact area between the cooling liquid and the heat source, increases the heat dissipation area of the heat dissipation plate surface at the place, and improves the heat dissipation efficiency, while the turbulence post 15 at the place has a certain interference effect on the cooling liquid flowing at the place, so as to prevent the uneven heat dissipation caused by the too fast flowing of the cooling liquid flowing to the communicating channel 402 at the place.
Secondly, when the cooling liquid flows to the liquid outlet area 403, the first splitter plate 12 positioned at the liquid outlet area 403 splits the cooling liquid flowing to the liquid outlet area 403, and as the first splitter plates 12 are the same in interval and the first splitter plates 12 are made of metal copper, the cooling liquid uniformly flows at the liquid outlet area 403, meanwhile, the first splitter plate 12 can conduct heat, the metal copper is not easy to deform in a high-temperature environment, the situation that the shape of the first splitter plate 12 is changed due to high temperature to cause uneven flow of the cooling liquid is avoided, the uniform distribution of temperature is realized at the liquid outlet area 403, and the whole heat dissipation plate can fully dissipate heat;
Further, when the cooling liquid flows to the liquid outlet area 403 through the communication flow channel 402, since the auxiliary plate two 11 is located at the liquid outlet area 403 and one end far away from the liquid outlet pipe 3 is rotatably connected with the plate body two 4, and the auxiliary plate two 11 is arc-shaped, the cooling liquid sequentially impacts one side of the protrusion of the auxiliary plate two 11 in the flowing process, so that the auxiliary plate two 11 swings left and right with the connection part of the auxiliary plate two 11 and the plate body two 4 as the axis, the auxiliary plate two 11 drives the cleaning block 13 located at two sides of the auxiliary plate two 11 to swing left and right when swinging, the cleaning block 13 is attached to the inner wall of the plate body two 4 when swinging left and right, and therefore the cleaning block 13 swings left and right when swinging, the impurity and the dirt of the inner wall adhesion of the liquid outlet region 403 of the second plate body 4 are scraped, excessive impurity and dirt adhered to the inside of the second plate body 4 are avoided, so that the cooling liquid flows unsmoothly, meanwhile, compared with the process of cleaning the inside of the second plate body 4 after long-time use, the cleaning block 13 is used for simply cleaning the inside of the second plate body 4, the cleaning of the inside of the second plate body 4 is more convenient for a later operator, simultaneously, the impurity and the dirt cleaned by the cleaning block 13 can be discharged from the inside of the second plate body 4 along with the cooling liquid under the driving of flowing cooling liquid, and the phenomenon that the impurity and the dirt are accumulated to form the dirt which is difficult to clean in the inside of the second plate body 4 under the accumulation of long time is avoided.
Finally, the cooling liquid flows out through the liquid outlet pipe 3 via the liquid outlet area 403, and is recovered into the supply source through the pipe system and then recycled.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
