DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present application in detail Figures 1-4 with reference to the attached drawings.

[0020] The embodiment of the present application discloses a cooling device for a UV inkjet printer. Refer to Figure 1 、 Figure 2, Figure 3 and Figure 4 , a cooling device for a UV inkjet printer. A heat dissipation cavity 10 is provided on one side inside the machine body 1. Since the inkjet table that supports the inkjet material generates high temperature when the inkjet printer is working, the heat dissipation cavity 10 provided inside the machine body 1 facilitates the transfer of heat into the heat dissipation cavity 10. A plurality of heat conducting sheets 11 are fixedly connected to one side inside the heat dissipation cavity 10. Through the plurality of heat conducting sheets 11 installed inside the heat dissipation cavity 10, it is convenient to conduct the heat from a high place to a low place. A plurality of arc-shaped pipes 12 are fixedly connected inside the heat dissipation cavity 10 through the plurality of heat conducting sheets 11. Through the connection between the plurality of heat conducting sheets 11 and the plurality of arc-shaped pipes 12, and the outer walls of the plurality of arc-shaped pipes 12 are respectively in contact with the plurality of heat conducting sheets 11 and uniformly penetrate inside each of the heat conducting sheets 11. When the coolant flows inside the arc-shaped pipes 12, the coolant will drive a part of the heat contained inside the heat conducting sheets 11 to dissipate the heat inside the heat dissipation cavity 10. A first communication cavity 14 is fixedly connected to one side inside the heat dissipation cavity 10, and a second communication cavity 15 is fixedly connected to the side corresponding to the first communication cavity 14 inside the heat dissipation cavity 10. One ends of the plurality of arc-shaped pipes 12 are all communicated with the first communication cavity 14, and the other ends of the plurality of arc-shaped pipes 12 are all communicated with the second communication cavity 15. By connecting the water inlet end of the arc-shaped pipe 12 to the second communication cavity 15 and connecting the water outlet end of the arc-shaped pipe 12 to the first communication cavity 14, it is convenient for the coolant to flow simultaneously inside the plurality of arc-shaped pipes 12, achieving the effect of facilitating the cooling and heat dissipation of the inkjet table of the machine body 1.

[0021] Refer to Figure 1 , Figure 3 and Figure 4, on one side of the outer surface of the body 1, a coolant flow chamber 3 is fixedly connected. On one side of the upper surface of the coolant flow chamber 3, a liquid inlet pipe 4 is fixedly connected. By opening the pipe cap on the outer wall of the liquid inlet pipe 4, coolant can be added into the coolant flow chamber 3 through the liquid inlet pipe 4. On one side of the outer wall of the coolant flow chamber 3, a return pipe 5 is provided. The coolant flow chamber 3 is connected to the first communication cavity 14 through the return pipe 5. One-way valves 13 are provided on the outer wall of the first communication cavity 14 corresponding to one side of the arc-shaped pipes 12. By connecting the coolant flow chamber 3 and the first communication cavity 14 through the return pipe 5, the coolant flowing in the several arc-shaped pipes 12 can enter the first communication cavity 14 and then flow into the coolant flow chamber 3 along the return pipe 5. By connecting the several one-way valves 13 provided on the outer wall of the first communication cavity 14 to the several arc-shaped pipes 12 respectively, and setting the one-way valves 13 to only allow inflow and not outflow, the coolant in the several arc-shaped pipes 12 can only flow into the first communication cavity 14, and the coolant in the first communication cavity 14 will not flow back into the arc-shaped pipes 12, thus facilitating the reciprocating circulation flow of the coolant. On one side of the outer surface of the body 1, a water pump 6 is fixedly connected. Several delivery pipes 7 are connected to the outer wall of the water pump 6. The water pump 6 is connected to the coolant flow chamber 3 through a delivery pipe 7 on one side, and the water pump 6 is connected to the second communication cavity 15 through a delivery pipe 7 on the other side. By connecting the coolant flow chamber 3 and the second communication cavity 15 through the delivery pipes 7 on both sides of the outer wall of the water pump 6, the coolant in the coolant flow chamber 3 can be transported into the second communication cavity 15 along the delivery pipe 7 by the water pump 6. Since the second communication cavity 15 is connected to the several arc-shaped pipes 12, the coolant can then be transported into the several arc-shaped pipes 12 along the delivery pipe 7 for flow.

[0022] Refer to Figure 1 and Figure 2 , several heat dissipation holes 2 are opened on both sides of the side surface of the body 1. On one side of the inside of the body 1, a fixing plate 8 is fixedly connected. On one side of the side wall of the fixing plate 8, several heat dissipation fans 9 are provided. At the four corners of the lower surface of the body 1, support feet 16 are fixedly connected. Through the several heat dissipation holes 2 opened on both sides of the side wall of the body 1, it is convenient for the air inside the body 1 to communicate. By installing the several heat dissipation fans 9 on the fixing plate 8, the outside air flow can be transported into the heat dissipation cavity 10 through the several heat dissipation fans 9, and the internal air flow rate can be increased. By starting the several heat dissipation fans 9 to blow air for heat dissipation in the gaps between the several heat conducting sheets 11 and discharging through the several heat dissipation holes 2 on the other side, the heat absorbed by the several heat conducting sheets 11 can be effectively blown and dissipated. By installing the support feet 16 at the four corners of the bottom of the body 1, the whole body 1 can be supported by the several support feet 16, and the bottom of the body 1 can be kept in contact with the outside air flow, achieving the effect of reducing the temperature of the painting table on the top of the body 1 and ensuring the quality of painting.

[0023] The implementation principle of the cooling device of a UV inkjet printer in an embodiment of this application is as follows: When the inkjet printer is working, the printing table that supports the printing material will generate high temperature. A number of heat conducting sheets 11 are installed in the heat dissipation cavity 10 opened inside the machine body 1, so that the heat of the printing table is conducted into the heat dissipation cavity 10. The outer walls of a number of arc-shaped pipes 12 are in contact with a number of heat conducting sheets 11 respectively and uniformly penetrate inside each heat conducting sheet 11. Subsequently, since the water pump 6 is connected to the coolant flow chamber 3 through the delivery pipe 7 on one side and the water pump 6 is connected to the second communication cavity 15 through the delivery pipe 7 on the other side, the coolant inside the coolant flow chamber 3 is then conveyed by the water pump 6 along the delivery pipe 7 into the second communication cavity 15. The second communication cavity 15 is connected to a number of arc-shaped pipes 12, and the coolant flow chamber 3 is connected to the first communication cavity 14 through the return pipe 5. Then the coolant is conveyed along the delivery pipe 7 into a number of arc-shaped pipes 12 for reciprocating cyclic flow to take away heat. At the same time, by starting a number of cooling fans 9 to blow air for heat dissipation in the gaps between each heat conducting sheet 11 and discharging through a number of heat dissipation holes 2 on the other side, the heat absorbed by a number of heat conducting sheets 11 can be effectively blown for heat dissipation, thereby increasing the cooling speed of the printing table.
