[0026] Reference Figure 1-Figure 5 A liquid crystal OLED display cooling device includes a display body 1, a rotatable reciprocating screw 101 is installed inside the display body 1, and a driving machine 3 is also installed inside the display body 1. The reciprocating screw 101 is then connected to the output end of the driving machine 3 through a pulley for driving the reciprocating screw 101 to rotate, and then the wiping plate 2 is threadedly connected to the reciprocating screw 101 through a movable block. When the reciprocating screw 101 rotates, the wiping plate 2 can slide. This is the prior art.

[0027] And refer to Figure 3 , Figure 4 or Figure 5 A working box 4 is also installed in the display screen body 1, and a limit box 5 is fixedly connected to the top of the working box 4, and a push rod 6 is slidably connected to the limit box 5, and one end of the push rod 6 extends to the outside of the limit box 5 and is fixedly connected to a contact wheel 601, and a connecting seat is provided on the contact wheel 601, and then the contact wheel 601 is rotatably connected to the connecting seat through a rotating shaft so that it can rotate on the connecting seat, and one end of the reciprocating screw rod 101 extends into the limit box 5, and a cam 401 is fixedly installed on the reciprocating screw rod 101, and a push rod 6 is slidably connected to the limit box 5, and then the contact wheel 601 is fitted and rolled with the outer wall of the cam 401, so that the contact wheel 601 can roll along the outer wall of the cam 401, so that the push rod 6 can reciprocate and move up and down on the limit box 5, and in the limit box 5, An airbag 501 is installed, and a current limiting box 7 is fixedly connected to the top of the limit box 5, and one side of the current limiting box 7 is connected to an external coolant supply device through a pipeline, and the other side of the current limiting box 7 is connected to the wiping plate 2 through a pipeline, so that it can provide coolant for the wiping plate 2, a baffle 701 is slidably connected in the current limiting box 7, and a connecting rod 702 is fixedly connected to the bottom of the baffle 701, and the connecting rod 702 extends to the limit box 5 where a contact plate is fixed, and then the outer wall of the airbag 501 is respectively fitted with the push rod 6 and the contact plate, so that the airbag 501 can be used as a buffer connection part between the push rod 6 and the contact plate, and a return spring 602 is sleeved on the push rod 6, and the two ends of the return spring 602 are respectively fixedly connected to the contact wheel 601 and the limit box 5, so that the contact wheel 601 can continuously roll in fit with the outer wall of the cam 401.

At the same time, when the push rod 6 is in the process of rising, this is a process, the top of the push rod 6 will squeeze the airbag 501, and when the airbag 501 is squeezed, it will drive the connecting rod 702 to drive the baffle 701 to move upward, thereby blocking the circulating liquid in the flow limiting box 7. When the cam 401 drives the push rod 6 to descend, this is the second process, so that the baffle 701 descends, thereby allowing the liquid in the flow limiting box 7 to circulate, and then the transported coolant can be intermittently supplied to reduce waste. At the same time, it ensures that an appropriate amount of coolant is supplied to the wiping cloth, and can also prevent the phenomenon of excessive cooling performance, avoid unnecessary energy waste, and thus save energy costs.
