Abstract

The present application discloses a rotary liquid distributor for a liquid-cooled tank, and a liquid-cooled tank. The rotary liquid distributor includes a liquid distribution cavity and a liquid distribution arm provided in the liquid distribution cavity. The liquid distribution cavity rotates around a central shaft thereof. A plurality of the liquid distribution arms are uniformly distributed in a circumferential direction of the liquid distribution cavity. That is, the liquid distribution arm rotates with the liquid distribution cavity. Then, a liquid distribution outlet is provided between a first end and a second end of the liquid distribution arm. The liquid distribution outlet is located on a side of the liquid distribution arm facing away from a rotating direction.

First claim

The invention claimed is:

1. A rotary liquid distributor in a liquid-cooled tank, comprising:
a liquid distribution cavity, the liquid distribution cavity having a central shaft, and the liquid distribution cavity rotating around the central shaft in a first direction;

wherein a liquid distribution outlet is provided between the first end and the second end of the liquid distribution arm, and the liquid distribution outlet is located on a side of the liquid distribution arm facing away from the first direction;
the liquid distribution outlet allows a cooling liquid flowing into the liquid distribution cavity to flow out of the rotary liquid distributor, and
wherein the rotary liquid distributor is provided at the bottom end of the liquid-cooled tank, and the central shaft is provided in a second direction from the bottom end of the liquid-cooled tank to the top end.

2. The rotary liquid distributor according to claim 1 , wherein the liquid distribution outlet at least comprises a first liquid distribution outlet at the first end of the liquid distribution arm.

3. The rotary liquid distributor according to claim 1 , wherein the liquid distribution outlet at least comprises a first liquid distribution outlet at the first end of the liquid distribution arm and a second liquid distribution outlet at the second end of the liquid distribution arm, and when the second liquid distribution outlet rotates at a constant speed in the first direction, a linear rotation speed of the second liquid distribution outlet is not less than a flow speed of the cooling liquid.

4. The rotary liquid distributor according to claim 1 , wherein a first diversion port is provided between the first end and the second end of the liquid distribution arm, the first diversion port is externally connected with a liquid distribution sub-pipe relative to the liquid distribution arm, the liquid distribution outlet is provided at an outer end of the liquid distribution sub-pipe, and an axis of the liquid distribution sub-pipe forms a predetermined angle with an axis of the liquid distribution arm.

5. The rotary liquid distributor according to claim 4 , wherein the liquid distribution outlet is inclined towards the second end of the liquid distribution arm relative to the first diversion port.

6. The rotary liquid distributor according to claim 4 , wherein the rotary liquid distributor is provided at a bottom end of a liquid-cooled tank, the central shaft is provided in a direction from the bottom end of the liquid-cooled tank to a top end, and the liquid distribution outlet is inclined towards the top end of the liquid-cooled tank relative to the first diversion port.

7. The rotary liquid distributor according to claim 1 , wherein
the cross section of the liquid distribution cavity is circular in the direction of the central shaft; and/or,
the cross section of the liquid distribution arm is oval in the direction of the axis of the liquid distribution arm, and a minor axis of the oval is parallel to the central shaft.

8. The rotary liquid distributor according to claim 1 , wherein a plurality of second diversion ports are uniformly distributed in the circumferential direction of the liquid distribution cavity relative to the central shaft, and the first end of the liquid distribution arm is connected to the second diversion port.

9. The rotary liquid distributor according to claim 8 , wherein the plurality of second diversion ports are distributed centrally symmetrically relative to the central shaft in the circumferential direction of the liquid distribution cavity;
the first end of the liquid distribution arm is detachably connected to the second diversion port, and the rotary liquid distributor further comprises a diversion cover for closing the second diversion port to which the liquid distribution arm is not connected.

10. The rotary liquid distributor according to claim 1 , wherein a plurality of the rotary liquid distributors are uniformly arranged in a plane perpendicular to the second direction.

11. The rotary liquid distributor according to claim 10 , wherein an end of the liquid distribution cavity facing away from the second direction is provided with a liquid distribution inlet, the liquid distribution inlet is externally connected with a liquid inlet sub-pipe, the liquid inlet sub-pipe communicates with a liquid inlet main pipe, and the liquid inlet main pipe also communicates with a liquid inlet at the bottom end of the liquid-cooled tank; and
an axis of the liquid inlet sub-pipe coincides with the central shaft whereby the liquid distribution cavity rotates around the liquid inlet sub-pipe in the first direction.

12. A liquid-cooled tank, wherein a bottom end of the liquid-cooled tank is provided with a liquid inlet allowing the circular inflow of a cooling liquid, and a top end of the liquid-cooled tank is provided with a liquid outlet allowing the circular outflow of the cooling liquid; and the liquid inlet communicates with a liquid distributor at the bottom end of the liquid-cooled tank, wherein the liquid distributor is the rotary liquid distributor according to claim 1 .

13.
