[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are intended to explain the present invention rather than to limit it.

[0030] like Figure 1 , Figure 2 As shown, a three-dimensional rotating bracket type flushing device includes a track 6, a guide block, a sleeve 1 and a flushing pipe 7.

[0031] The track 6 is vertically arranged at the intersection of the cooling triangle radiator. The guide block is mounted on the track 6 and can move up and down along the track. One side of the guide block extends out of the track 6 and is connected to the sleeve. The sleeve can rotate along the guide block. One end of the flushing pipe 7 is connected to the sleeve, and the other end extends along the horizontal direction of the radiator. The flushing pipe 7 can rotate along its axial direction to adjust the flushing angle.

[0032] The flushing pipe 7 of the flushing device is connected to the guide block through a sleeve. The height of the flushing pipe 7 can be adjusted through the guide block. At the same time, the position of the flushing pipeline can be driven by rotating the sleeve, so that both heat dissipation surfaces can be flushed. Secondly, by rotating the circumferential angle of the flushing pipe 7, the radiator can be flushed without dead angles, thereby improving the heat dissipation efficiency of the radiator.

[0033] The track 6 is provided with a T-slot, and the guide block includes a slider 5 and a support column 2. The slider 5 is mounted in the T-slot of the track. The slider 5 is provided with a horizontal connecting arm, which extends horizontally to the outside of the T-slot. The support column 2 is fixedly connected to the connecting arm, and the sleeve is connected to the support column.

[0034] The sleeve 1 is a cylindrical structure with an opening at the bottom. The sleeve 1 is sleeved on the support column 2 from top to bottom. An introduction groove is arranged on the side wall of the sleeve 1 along its axial direction. The open end of the introduction groove is located at the lower end of the sleeve. When installing, the introduction groove is opposite to the connecting arm. The sleeve is installed on the support column. A rotation groove 3 is arranged on the side wall of the sleeve along its circumference. The rotation grooves are located at the upper end of the introduction groove and are interconnected to form a T-shaped structure. When the sleeve is sleeved on the support column, the connecting arm is located in the rotation groove. When the connecting arm is located at the end of the rotation groove, the flushing pipe 7 is parallel to one of the radiators.

[0035] A positioning mechanism is also provided on the side wall of the sleeve for positioning the rotation angle of the sleeve. The positioning mechanism is a top screw, which is horizontally arranged on the side wall of the sleeve through a thread. The end of the top screw passes through the sleeve to abut against the side wall of the support column 2 to achieve circumferential positioning of the sleeve.

[0036] The angle formed by the two ends of the rotating groove and the center of the sleeve is less than or equal to the angle of the cooling triangle radiator 11.

[0037] The length of the sleeve 1 is greater than that of the support column 2. A mounting hole is provided at the lower part of the sleeve. The end of the flushing pipe is located in the mounting hole through a thread. A locking nut 4 is also provided on the flushing pipe. When adjusting the flushing angle, the locking nut 4 is loosened to rotate the flushing pipe 7. After adjustment, the locking nut makes it abut against the outer wall of the sleeve to complete the angle positioning.

[0038] The flushing pipe 7 is connected to the water source hose through the hose connector 9, and the water source is drained into the flushing pipe 7 through the pipe. In order to ensure the uniformity of flushing, a plurality of water holes are arranged on the side wall of the flushing pipe 7 along its axial direction, and a flushing nozzle is arranged on each water hole.

[0039] A pulley is arranged at the upper end of the track, one end of the traction rope passes around the pulley and is detachably connected to the connecting arm, and the other end of the traction rope is connected to the motor. The motor rotates and the electric slider of the traction rope slides up and down along the T-slot to complete the flushing of the radiator.

[0040] See also Figure 3 When the flushing device is working, the water source hose 10 is connected to the hose connector 9 of the flushing pipe 7 fixed on the three-dimensional rotating bracket. The flushing pipe 7 is parallel to one side of the radiator 11 in the cooling triangle radiator, and the flushing nozzle 8 is also facing this side of the radiator. The flushing pipe 7 moves up and down along the vertical track 6 driven by the three-dimensional rotating bracket. After the flushing nozzle 8 sprays water to flush this side of the radiator, it is rotated horizontally through the three-dimensional rotating bracket to a position parallel to the other side of the radiator in the cooling triangle. The flushing nozzle is rotated axially along the center line of the flushing pipe through the three-dimensional rotating bracket, so that the flushing nozzle faces the radiator surface parallel to the flushing pipe 7, and then moves up and down along the vertical track guide groove to complete the flushing of the radiators on both sides of the cooling triangle.

[0041] After flushing one group of cooling triangle radiators 11, the hose is connected to the flushing device of the next group of cooling triangle radiators for flushing. The flushing pipe and the three-dimensional rotating bracket can be fixedly installed on the track of each cooling triangle with the slider, and can also be disassembled and installed in the guide groove of other cooling triangles for use.

[0042] The present invention is applied to a flushing device for a large row of cooling triangles. The flushing device effectively solves the problem of operation obstruction when a traditional flushing device in an annular track is applied to a radiator with a multi-layer arrangement, while ensuring that the flushing range achieves a good flushing effect and improves the cooling effect of the radiator.
