Fig. 5 is a partial structural schematic diagram of the liquid cooling tank 1 according to the embodiment of the present application. As shown in fig. 1 and 5, the liquid cooling box 1 further includes a bottom plate, a side plate 10 and a flow guide wall 11, the bottom plate is rectangular, the side plate 10 is disposed along the perimeter of the bottom plate, and the flow guide wall 11 is disposed on the bottom plate and located inside the side plate 10.

In this embodiment, the first electromagnetic shielding heat conducting structure 12 has a rectangular perimeter, the right side wall of the first electromagnetic shielding heat conducting structure 12 is entirely contacted with the flow guiding wall 11, and the flow guiding wall 11 limits the first electromagnetic shielding heat conducting structure 12 on the one hand and forms a larger contact surface on the other hand, thereby improving the heat dissipation efficiency.

In the embodiment of the present application, the cover plate 3 is made of a heat conductive material, for example, the cover plate 3 may be made of a copper metal plate.
Referring to fig. 1 and 5, the flow guide channel includes a liquid inlet channel 111 and a liquid outlet channel 112 parallel to each other, the side plate 10 has a liquid inlet 101 corresponding to the liquid inlet channel 111, and the side plate 10 has a liquid outlet 102 corresponding to the liquid outlet channel 112. The cooling liquid enters the liquid inlet flow channel 111 from the liquid inlet 101, enters the liquid outlet flow 112, and then flows out from the liquid outlet 102, and the cooling liquid absorbs heat and takes away the heat in the process.
As shown in fig. 5, the flow guiding channel further includes a transition flow channel 113, one end of the transition flow channel 113 is connected to one end of the liquid inlet flow channel 111 away from the liquid inlet 101, and the other end of the transition flow channel 113 is connected to one end of the liquid outlet flow channel 112 away from the liquid outlet 102. It is understood that the inlet flow path 111 and the outlet flow path 112 extend in the longitudinal direction and the transition flow path 113 extends in the transverse direction. That is, the flow guide channel forms a zigzag shape, and the cooling liquid is turned twice.
It should be noted that the inlet flow path 111 and the outlet flow path 112 may also be arranged in a zigzag shape, for example, the inlet flow path 111 may be arranged in a structure with non-uniform width, for example, it may be narrowed at the middle portion, or a right-angle section may be arranged at the narrowed end.
And the bottom surface of the liquid outlet flow passage 112 is higher than the bottom surface of the transition flow passage 113. That is, it can be understood that the cooling liquid entering the deeper transition flow channel 113 will be deposited downward in the transition flow channel 113, and then enter the shallower liquid outlet flow channel 112, so as to reduce the flow velocity of the cooling liquid and prevent the cooling liquid from generating turbulence when turning.
The transition flow channel 113 is provided with a strip-shaped spoiler 1131 extending along the length direction thereof, and the strip-shaped spoiler 1131 protrudes out of the bottom surface of the liquid outlet flow channel 112. The strip-shaped turbulence blocks 1131 are arranged in the transition flow channel 113, and the height of the strip-shaped turbulence blocks 1131 protrudes from the bottom surface of the liquid outlet channel 112, so that the cooling liquid cannot completely enter the liquid outlet channel 112 from the transition flow channel 113, and turbulence is further reduced.
It should be noted that the length and the width of the bar-shaped spoiler 1131 are both smaller than the length and the width of the transition duct 113, and in the embodiment of the present application, gaps are formed between the transition duct 113 and the bar-shaped spoiler 1131 in all of the front, rear, left, and right directions.
Fig. 6 is a schematic structural diagram of the spoiler assembly 2 according to an embodiment of the present application, and as shown in fig. 6, the spoiler assembly 2 includes a rotating base 21, a droplet-shaped spoiler column 22, and a driving mechanism 23. The rotating chassis 21 is circular, a plurality of water drop-shaped turbulence columns 22 are arranged on the rotating chassis 21, and the driving mechanism 23 is used for driving the rotating chassis 21 to rotate so as to adjust the direction of the water drop-shaped turbulence columns 22.
In this embodiment, there are two rotating base plates 21, wherein one rotating base plate 21 is disposed in the liquid inlet flow channel 111 for adjusting the flow rate and direction of the liquid coolant when entering the liquid coolant; another rotary chassis 21 is arranged in the liquid outlet channel 112 for adjusting the flow rate and direction of the cooling liquid when the cooling liquid is discharged. The number of the rotating base plates 21 in the liquid inlet flow path 111 and the liquid outlet flow path 112 is not limited to one, and two rotating base plates 21 may be provided in the liquid inlet flow path 111 or two rotating base plates 21 may be provided in the liquid outlet flow path 112.
The drive mechanisms 23 correspond to the rotary chassis 21 one by one and drive the rotary chassis 21 to rotate.
In the embodiment of the present application, the bottom plate of the liquid cooling tank 1 is recessed inwards to form the mounting groove 100, the mounting groove 100 is circular, and each mounting groove 100 is provided with one rotating chassis 21, that is, the number of the mounting grooves 100 is the same as the number of the rotating chassis 21. The driving motor 23 is arranged at the bottom of the mounting groove 100, a center column is arranged at the center of the lower surface of the rotating chassis 21, and the output end of the driving motor 23 is engaged with the center column of the rotating chassis 21.
It should be noted that a seal is maintained between the rotary base plate 21 and the mounting groove 100 to prevent the coolant from corroding the driving motor 23.
In this embodiment, the driving motor 23 may be selected as a brushless motor so as to freely rotate the rotating chassis 21 in a clockwise or counterclockwise direction.
Further, the arrangement direction of the respective droplet-shaped turbulence columns 22 on any one of the rotary base plates 21 is the same. It should be noted that the arrangement direction of the droplet-shaped turbulence columns 22 refers to a direction in which the central axis extends from the large-diameter end to the small-diameter end, the arrangement directions of the droplet-shaped turbulence columns 22 of the same rotating chassis 21 are the same, and when the rotating chassis 21 rotates, each droplet-shaped turbulence column 22 always points to the same direction, which is convenient for adjusting the flow direction of the coolant.
The working principle of the liquid-cooled vehicle-mounted power supply provided by the invention is as follows: cooling liquid is input from the liquid inlet 101, enters the liquid inlet flow channel 111, sequentially passes through the transition flow channel 113 and the liquid outlet flow channel 112, and finally flows out from the liquid outlet 102, the water drop-shaped turbulence column 22 of the turbulence assembly 2 can reduce turbulence, meanwhile, the driving mechanism 23 of the turbulence assembly 2 can adjust the rotation angle of the rotating floor 21, so that the direction of the water drop-shaped turbulence column 22 is controlled, the directions of the water drop-shaped turbulence column 22 are different, and the flowing direction of the cooling liquid is changed; the second electromagnetic shielding heat-conducting structure 31 is annularly arranged on the periphery of the first heat-generating device 41 to timely conduct the heat of the latter to the cooling liquid, and the first electromagnetic shielding heat-conducting structure 12 is annularly arranged on the periphery of the second heat-generating device 51 to timely conduct the heat of the latter to the cooling liquid.
