The joint on side cover 1 62 is the liquid inlet channel, and the joint on side cover 2 63 is the liquid discharge channel. The cold air in the outer cover 61 and the liquid in the side cover are heat-conducted through the heat conduction channel 66. The outer side of the outer cover 61 is fixedly connected to the bracket 698.

[0043] The channel assembly seat 64 can pull the heat-conducting channel 66 on the channel assembly seat 64 to move inside the outer cover 61, providing an environment for self-decontamination of the heat-conducting channel 66.

[0044] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8The changing unit 65 is installed between the channel assembly seat 64 and the second side cover 63, and the changing unit 65 is used to pull the channel assembly seat 64 to change;

The hoop 651 is also equipped with a spiral beryllium copper wire.

[0046] The deformation of the spiral beryllium copper wire can pull the channel assembly seat 64 to quickly move toward the side cover 1 62, so that the channel assembly seat 64 stops moving after touching the side cover 1 62. During this period, the channel assembly seat 64 is impacted and shaken, and the debris inside and outside the heat conduction channel 66 is shaken off, so as to achieve self-decontamination of the inside and outside of the heat conduction channel 66.

[0047] A baffle is installed at the connection of the side cover 62. The baffle is made of TPE material. The installation of this baffle can reduce the impact loss between the channel assembly seat 64 and the wall of the side cover 62, and can reduce the noise caused by the impact.

[0049] The back-and-forth traction unit 67 comprises a hydraulic prime mover 671, a rotating disk 1 672 and a movable seat 673. The hydraulic prime mover 671 is arranged at the end of the side cover 1 62 which is far from the outer cover 61. The rotating part of the hydraulic prime mover 671 extends into the inside of the side cover 1 62. The rotating part of the hydraulic prime mover 671 is connected to the rotating disk 1 672. The movable seat 673 is arranged on one side of the channel assembly seat 64. The movable seat 673 is arranged with a compression bar 674 which cooperates with the rotating disk 1 672. The discharge end of the hydraulic prime mover 671 is connected to the joint of the side cover 1 62 via the channel. The rotating disk 1 672 is arranged with an inclined wall for squeezing the compression bar 674 and a horizontal wall for cancelling the squeezing compression bar 674.

[0050] The hydraulic prime mover 671 pulls the variable unit 65 and the stirring unit 68 through the flow of liquid, and there is no need to add motors or other devices for pulling work, thereby reducing the energy consumption of the device.

[0051] Reference Figure 3 and Figure 5The stirring unit 68 is mounted on the channel assembly seat 64 and is used to perform autonomous stirring on the cold air in the outer cover 61; the stirring unit 68 includes a rotating rod 681 and a stirring bar 682, the rotating rod 681 is screwed on the channel assembly seat 64 and is arranged opposite to the heat conduction channel 66, the rotating rod 681 is provided with the stirring bar 682, and the stirring bar 682 is separated between the arc-shaped baffles 643.

[0052] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 The rotating traction unit 69 is arranged in the side cover 63, and is used to use the change of the channel assembly seat 64 to pull the stirring unit 68 to rotate; the rotating traction unit 69 includes a rotating disk 691, a rotating ring 692 and a movable channel 693, the rotating disk 691 is arranged on one end of the rotating rod 681, and the rotating ring 692 is screwed on the channel assembly seat 64. A plurality of teeth are reserved at equal intervals on the outer circumference of the rotating disk 691 and the circumference of the inner wall of the rotating ring 692. The rotating disk 691 and the rotating ring 692 are engaged with each other through the teeth. The movable channel 693 is arranged in the side cover 63, and the inner surface of the movable channel 693 is reserved with a skewed Groove 694, a variable rod 695 is installed on the rotating ring 692, one end of the variable rod 695 extends into the movable channel 693, and the variable rod 695 is connected to the rotating platform 696 via an overrunning clutch. Through the installation of the overrunning clutch, when the channel assembly seat 64 moves toward one side of the side cover 63 to pull the variable unit 65 to store kinetic energy, the rotating traction unit 69 can pull the stirring unit 68 to rotate, so that the channel assembly seat 64 can move in the reverse direction to obtain a huge impact force. A variable platform 697 that can be movably installed in the groove 694 is installed on the rotating platform 696. The installation of this structure can pull the stirring unit 68 to rotate through the back and forth traction unit 67.

[0053] During operation, cold air is injected into the liquid inlet channel on the outer cover 61, and liquid is injected into the liquid injection end of the hydraulic prime mover 671.

The cold air and liquid touch the inner and outer walls of the heat conduction channel 66 to achieve the purpose of heat conduction.

[0054] The liquid passes through the hydraulic prime mover 671 to rotate the rotating part, and the rotating part of the hydraulic prime mover 671 pulls the rotating disk 1 672 to rotate. The skewed wall on the rotating disk 1 672 compresses the compression bar 674, so that the movable seat 673 pulls the channel assembly seat 64 to move rightward. During this period, the movable rod 652 compresses the spiral beryllium copper wire in the hoop 651 to shorten the spiral beryllium copper wire; when the compression bar 674 moves to the horizontal wall of the rotating disk 1 672, the spiral beryllium copper wire extends, and the channel assembly seat 64 is quickly pressed to the left, and the left side of the channel assembly seat 64 hits the baffle plate on the side cover 1 62. During the impact and shaking period of the channel assembly seat 64, the heat conduction channel 66 is pulled to shake, so as to continuously clean the inside and outside of the heat conduction channel 66 by itself, and the entire back and forth movement of the channel assembly seat 64 can also increase the stirring of the cold air and enhance the heat conduction function;

[0055] During the rightward movement of the channel assembly seat 64, the channel assembly seat 64 pulls the rotating ring 692 and the changing rod 695 to move, so that the changing rod 695 pulls the changing table 697 on the rotating platform 696 to move in the groove 694, so that the rotating platform 696 rotates, and the rotating platform 696 pulls the changing rod 695 and the rotating ring 692 to rotate via the overrunning clutch, and the rotating ring 692 pulls the rotating rod 681 to rotate via the rotating disk 2 691, and the rotating rod 681 pulls the stirring bar 682 to rotate, thereby achieving the purpose of automatically stirring the liquid and enhancing the heat conduction function.

[0056] Reference Figure 1 One end of the refrigeration device 7 is connected to the inlet channel via water pipe 2 72 , and the other end of the refrigeration device 7 is connected to the discharge channel via water pipe 1 71 .

[0057] The refrigeration device 7 sends the refrigerated air to the outer cover 61 through the water pipe 2 72. The cold air removes heat from the circulating cooling module 6. After heat conduction, the cold air enters the refrigeration device 7 through the water pipe 1 71 to perform refrigeration again, thereby achieving rapid heat removal of the water flowing through the circulating cooling module 6.
