[0066] The cooling mechanism 5 in the above embodiment adopts an air cooling structure, which is low in cost and stable in performance, and does not need frequent maintenance.

[0067] In one embodiment, the heat dissipation member 51 includes a plurality of heat dissipation pipes 510, an upper water box 511 and a lower water box 512.

[0068] The plurality of heat dissipation pipes 510 are arranged between the upper water box 511 and the lower water box 512, and the two ends of each heat dissipation pipe 510 are respectively communicated with the inner cavities of the upper water box 511 and the lower water box 512.

[0069] At least one partition is arranged in the inner cavity of the upper water box 511, and the at least one partition divides the inner cavity of the upper water box 511 into a water inlet cavity and a water outlet cavity; the water inlet connector and the water outlet connector are arranged on the upper water box 511 and respectively communicated with the water inlet cavity and the water outlet cavity.

[0070] The heat dissipation member 51 further includes an outer frame formed by an upper baffle 513, a lower baffle 514, a left fixed plate 515 and a right fixed plate 516; the upper baffle 513 is arranged on the top of the upper water box 511, and the lower baffle 514 is arranged on the bottom of the lower water box 512.

[0071] In one embodiment of the present embodiment, as shown in Figures 12-15 the middle position of the inner cavity of the upper water box 511 is provided with a partition, which divides the inner cavity of the upper water box 511 into two chambers, one of which is a water inlet cavity and the other of which is a water outlet cavity; the lower water box 512 is not provided with a partition, and the inner cavity thereof constitutes a water passing cavity.

[0072] Taking the heat dissipation member 51 with 32 heat dissipation pipes 510 as an example, 16 heat dissipation pipes 510 are communicated with the water inlet cavity in the upper water box 511 and the water passing cavity in the lower water box 512, and the other 16 heat dissipation pipes 510 are communicated with the water passing cavity in the lower water box 512 and the water outlet cavity in the upper water box 511; the water flow direction is shown by arrows in Figure 15 When the first water pump 41 pumps water, the water enters the water inlet cavity in the upper water box 511 through the water inlet connector, is divided into 16 water paths, respectively flows from the water inlet cavity to the water passing cavity through the 16 heat dissipation pipes 510 communicated with the water inlet cavity, then flows from the water passing cavity to the water outlet cavity through the other 16 heat dissipation pipes 510 communicated with the water outlet cavity, and finally flows out from the water outlet connector to the circulating water outlet.

[0073] In the above embodiment, the water flows downward through one batch of the heat dissipation pipes 510 in the heat dissipation member 51 and then flows upward through another batch of the heat dissipation pipes 510, which can increase the contact area of the water with the external airflow, improve the heat dissipation efficiency, and help shorten the cooling time due to the large water flow entering the heat dissipation member 51 each time.

[0074] In another embodiment of the present embodiment, one horizontal and one vertical partition are arranged in the inner cavity of the upper water box 511; the horizontal partition divides the inner cavity of the upper water box 511 into a front cavity and a rear cavity, and the rear cavity constitutes an upper water passing cavity; the vertical partition is arranged at the middle position of the front cavity and divides the front cavity into a water inlet cavity and a water outlet cavity; and a partition is arranged at the middle position of the inner cavity of the lower water box 512 to divide the inner cavity of the lower water box 512 into a left water passing cavity and a right water passing cavity.

[0075] One batch of the heat dissipation pipes 510 connecting the water inlet cavity and the right water passing cavity is set as a heat dissipation pipe group A, one batch of the heat dissipation pipes 510 connecting the right water passing cavity and the upper water passing cavity is set as a heat dissipation pipe group B, one batch of the heat dissipation pipes 510 connecting the upper water passing cavity and the left water passing cavity is set as a heat dissipation pipe group C, and one batch of the heat dissipation pipes 510 connecting the left water passing cavity and the water outlet cavity is set as a heat dissipation pipe group D; in specific implementation, as shown in the figure, the water flows into the water inlet cavity from the water inlet connector, flows downward into the right water passing cavity through the heat dissipation pipe group A, flows upward into the upper water passing cavity through the heat dissipation pipe group B, flows downward into the left water passing cavity through the heat dissipation pipe group C, and finally flows upward to the water outlet cavity through the heat dissipation pipe group D and flows out from the water outlet connector.

In order to ensure the up-and-down cross flow of water from the water inlet cavity to the water outlet cavity, the lower ends of the two heat dissipation pipes 510 connected with the same upper water passing cavity are respectively connected with different lower water passing cavities.
