[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Figure 1 It is a schematic diagram of the overall structure of the utility model, and combined with Figure 2 and Figure 4 As shown, the cooling equipment of the radio and television transmitter includes a water-cooling pipe 1 and a cold water tank 2. The water-cooling pipe 1 is a multi-layer structure and is wound around the outside of the transmitter body. The lower end of the water-cooling pipe 1 is connected to a water inlet pipe 7, and the upper end of the water-cooling pipe 1 is connected to a water return pipe 5. A water pump 8 is installed at the bottom of the cold water tank 2. The water outlet end of the water pump 8 is connected to the water inlet end of the water inlet pipe 7, and the water outlet end of the return pipe 5 extends to the upper end of the cold water tank 2. A sprinkler plate 6 is installed at the water outlet end of the return pipe 5.

[0025] See also Figure 4 As shown, a water distribution plate 3 is fixed inside the cold water tank 2 and below the watering plate 6 , and a plurality of water leakage holes 10 are formed on the water distribution plate 3 .

[0026] A water guide cone 9 is connected inside the cold water tank 2 and between the water distribution plate 3 and the water sprinkling plate 6. The water guide cone 9 is small at the top and large at the bottom.

[0027] Through the above technical solution:

[0028] When in use, the water pump 8 is used to extract the cold water in the cold water tank 2, and the cold water is sent to the water cooling pipe 1 from the bottom through the water inlet pipe 7. The cold water moves up layer by layer from the water cooling pipe 1 until the water cooling pipe 1 is filled with cold water. The water cooling pipe 1 filled with cold water can be used to dissipate the heat of the transmitter body, and the water passing through the water cooling pipe 1 is sent into the sprinkler plate 6 from the return pipe 5 at the upper end. The sprinkler plate 6 is used to disperse the water after heat exchange once, which can increase the contact area with the air and thus accelerate the cooling. The water sprinkled from the sprinkler plate 6 falls from the water guide cone 9 onto the water distribution plate 3, and then falls back from the multiple leakage holes 10 on the water distribution plate 3. The water after heat exchange can be dispersed for a second time and then fall back into the cold water tank 2, which can further accelerate the cooling of the water after heat exchange.

[0029] In addition, see Figure 1 and Figure 3 As shown, the radio and television transmitter cooling device also includes a plurality of heat-conducting parts 4, which are distributed around the transmitter body, and each heat-conducting part 4 includes a main heat sink 41, and a slot 44 matching the water-cooling tube 1 is provided on the side of the main heat sink 41 facing the transmitter body. After the main heat sink 41 is connected to the water-cooling tube 1, the inner end of the main heat sink 41 is attached to the outer wall of the transmitter body, and the outer end of the main heat sink 41 is symmetrically connected to two heat-conducting fins 42 inclined in opposite directions, and the heat-conducting fins 42 are also connected to the auxiliary heat sink 43, and the end of the auxiliary heat sink 43 facing away from the heat-conducting fin 42 is provided with a groove 45 matching the water-cooling tube 1, and a layer of thermal conductive silicone can be arranged on the inner wall of the slot 44 and the groove 45 to accelerate the heat dissipation, and the angle between the auxiliary heat sink 43 and the main heat sink 41 is 120°-150°.

[0030] Through the above, the end of the main heat sink 41 is attached to the outer wall of the transmitter body, which can cooperate with the water cooling of the water-cooling tube 1 to improve the heat dissipation efficiency of the transmitter body, and the main heat sink 41 is clamped on the water-cooling tube 1, and cooperates with the auxiliary heat sink 43 attached to the water-cooling tube 1, so as to dissipate the heat of the water-cooling tube 1 itself, and can reduce the temperature rise of water during the water-cooling heat exchange process of the water-cooling tube 1, and can effectively improve the heat dissipation effect during the continuous circulation heat dissipation process, wherein the heat conductive sheet 42 provided can increase the heat conduction area, which is conducive to the rapid dissipation of heat on the heat sink.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
