Note that the description of the following implementations is merely an example in nature, and the present invention is not intended to limit its application or its use, and the present invention is not limited to the following implementations.

Embodiment 1

(10) As shown in FIG. 1 to FIG. 3, provided is a passive pulse water flow adjustment device for water flow cooling. The device comprises a water storage container 1 and a pulse water flow adjustment structure, wherein the water storage container 1 is arranged in front of a to-be-cooled high-temperature wall surface through the pulse water flow adjustment structure, and the pulse water flow adjustment structure provides a non-continuous pouring pulse water flow for the high-temperature wall surface. This device is used to cool the high-temperature wall surface, and when being cooled, the high-temperature wall surface is poured by the pulse water flow. The passive pulse water flow adjustment device for water flow cooling in the present invention is separately arranged under each water outlet of a water film distribution device, which can adjust a continuous water flow into the pulse water flow. The device provides a pulse water cooling manner, so that the ratio of the water film evaporation heat exchange to the total heat exchange can be improved, and under the same heat exchange requirement, the total water film flow is effectively reduced, and the volume of a cooling water storage tank is reduced.

(11) Among them, the pulse water flow adjustment structure comprises a base 2, and an opening at the front end of the water storage container 1 forms a water outlet 3, the water storage container 1 is provided with installation nodes 4 disposed symmetrically on both sides, and the water storage container 1 is reversibly installed on the base 2 through the installation nodes 4, the base 2 is provided with a first limiting member 5 and a second limiting member 6 for limiting a counterclockwise turning angle and a clockwise turning angle of the water storage container 1.

(12) Specifically, the base 2 in this embodiment comprises two symmetrical triangular shaped brackets, and the tops of the triangular shaped brackets are respectively provided with an assembly groove 7 for installing the installation nodes 4, and the installation nodes 4 is rotatably connected with the assembly groove 7.

(13) The first limiting member 5 and the second limiting member 6 are arranged in parallel and the two ends thereof are respectively connected with two triangular shaped brackets, the first limiting member 5 and the second limiting member 6 are both located below the water storage container 1, and the first limiting member 5 is close to the back end of the water storage container 1, the second limiting member 6 is close to the front end of the water storage container 1. An installation height of the first limiting member 5 in the vertical direction is lower than that of the second limiting member 6 in the vertical direction, the first limiting member 5 and the second limiting member 6 are both rod-shaped.

(14) In this embodiment, the water storage container 1 is a rectangular parallelepiped, with one end thereof being closed, and the other end being open to form a water outlet 3. The water outlet 3 is an inclined cut. The water outlet 3 in this embodiment is a rectangle inclined cut, so that the entire water storage container is in the shape of a right-angled trapezoid. The bottom of the water outlet 3 is provided with a downward curved arc-shaped flow guide edge 8. The arc-shaped flow guide edge 8 can effectively prevent water splashing which causes waste.

(15) As shown in FIG. 4, the operation process of the passive pulse water flow adjustment device in the present invention is specifically as follows:

(16) 1. In an initial state, the water storage container 1 is empty, the overall center of gravity of the water storage container 1 is located behind the installation nodes 4 far away from the water outlet 3, the water storage container is turned counterclockwise until the first limiting member 5 and the water outlet 3 faces upwards;

(17) 2. Water flows into the water storage container from the water outlet 3. During a water storage process, the overall center of gravity of the water storage container moves toward the direction of the water outlet 3;

(18) 3. When the overall center of gravity of the water storage container moves to a position near the water outlet 3 in front of the installation nodes 4, the water storage container 1 is turned clockwise under the action of gravity until the second limit member 6, and the water flows out;

(19) 4. After the water flows out, the overall center of gravity of the water storage container moves again, and the water storage container is turned to the initial state.

(20) The pulse water flow adjustment device in the present invention realizes the pulse water flow by turning the water storage container, and the continuous water flow is changed to the pulse water flow. When the water film flow rate is 0, the temperature of the wall surface to be cooled temporarily increases, and then the water film flows down to take away the heat. And then the water flow stops, and repeat the process again and again. In this mode, a higher wall surface temperature increases the temperature of the water film, resulting in a higher evaporation rate of the water film, and achieving the purpose of increasing the ratio of the evaporation heat exchange to the total heat exchange in the water film. Furthermore, under the same heat exchange demand, the required total water film flow is effectively reduced, and the volume of the cooling water storage tank is reduced. The water flow adjustment device in this embodiment is more suitable for a non-vertical wall surface. Even if the water storage container 1 is stuck and unable to move due to extreme conditions such as rust, vibration, the water flow can continue to flow down from the water outlet 3 after the water in the water storage container 1 is full. Since the wall surface is the non-vertical wall surface, the water flows along the wall surface and does not fall directly, thus not affecting cooling.

Embodiment 2

(21) As shown in FIG. 5 to FIG. 7, on the basis of embodiment 1, the passive pulse water flow adjustment device for water flow cooling in the present embodiment further comprises a drainage structure, and the drainage structure is fixed on the base 2 and is located below the water outlet 3 of the water storage container 1. The drainage structure comprises a support frame 9 and a drainage plate 10, and the drainage plate 10 is a circular arc groove shape, the notch thereof is upward and located below the water outlet 3 of the water storage container 1, and one end of the drainage plate 10 is fixed on the base 2 through the support frame 9, and the other end forms a vertical drainage edge. The device in this embodiment is more suitable for use under a vertical wall surface condition. When being in use, the vertical drainage edge is close to a vertical wall surface 11, and the drainage plate 10 keeps the water in a state of sticking to the wall. If the water storage container 1 is stuck and unable to move due to extreme conditions such as rust, vibration, the water flow can continue to flow down from the water outlet 3 after the water in the water storage container 1 is full. The drainage plate 10 keeps the water in a state of sticking to the wall, ensures that the lower wall surface is always covered by the water film, prevents the water flow from directly falling off the plate, and ensures the reliable operation of the device.

(22) The foregoing implementations are only examples, and do not limit the scope of the present invention. These implementations can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the scope of the technical idea of the present invention.
