At this time, the fluid is injected into the tube bar, the fluid circulates inside the tube but absorbs heat while passing through the heat intake tube 24 to discharge the heat while passing through the heat discharge tube (25).

The fluid is circulated inside the tube by natural convection.

On the other hand, the transfer pipe 23 is further formed with a transfer member 30 for forcibly moving the fluid.

The transfer member 30 is located in the stator 31 formed of a coil wound around a specific portion of the transfer tube 23 and in the transfer tube 23 in which the stator 31 is positioned, thereby providing power to the stator 31. It consists of a rotating portion 32 for transferring the fluid while rotating according to the application.

That is, the rotating part 32 is a fixed rod 34 is formed in the longitudinal direction of the cylinder in the center of the cylindrical rotating body 33 in which the N pole and the S pole of the magnet are alternately formed.

In order to maintain the fixing bar 34 in a fixed state, the fixing piece 35 extends on the outer circumferential surface of the fixing bar 34 to be connected to the inner side of the rotating body 33.

In addition, the fan 36 is formed on the outer circumferential surface of the fixing rod 34 so that the rotating part 32 moves the fluid.

At this time, the fan 36 is located in the middle of the fixing rod 34, the fixing piece 34 is located at the upper and lower ends of the fixing rod 34, respectively.

The guards 37 are fixed inside the transfer pipe 23 adjacent to the upper and lower ends of the rotary part 32 so that the rotary part 32 is continuously positioned in the stator 31 without moving in the transfer pipe 23. The guard 37 has an opening 38 through which fluid flows.

On the other hand, if the heat suction tube 24 is molded using a material having excellent thermal conductivity such as aluminum, heat generated in the panel 11 can be quickly conducted to the fluid passing through the heat suction tube 24.

The heat suction tube 24 may be disposed to penetrate the fixing bar 21 to approach the rear surface of the panel 11.

In addition, when the heat dissipation tube 25 is molded using a material having excellent thermal conductivity such as aluminum, the fluid heated through the heat intake tube 24 quickly passes heat to the air while passing through the heat dissipation tube 25. .
