[0002] Broadcast and television microwave transmitters are key devices in broadcast and television signal transmission systems. Their primary function is to modulate broadcast and television signals (including audio and video) into microwave frequencies (typically between 300MHz and 300GHz) and then transmit them in a specific direction via an antenna. For example, in signal transmission at a local television station, the audio and video signals of a completed program are first sent to a microwave transmitter. After processing, they are then transmitted via microwaves to a nearby relay station or directly to a receiving antenna near the user's receiving end.

[0003] Most existing radio and television microwave transmitters are provided with heat dissipation vents on the surface of the radio and television microwave transmitters to dissipate the heat inside the radio and television microwave transmitters through the heat dissipation vents. However, radio and television microwave transmitters are generally installed on broadcast towers for use. Radio and television microwave transmitters are located at a high altitude, and the humidity in the air varies greatly. Under certain altitudes and meteorological conditions, the air humidity may be very high. This moisture can easily enter the interior of the radio and television microwave transmitter through the heat dissipation vents, and the moisture that enters may cause damage to the internal components of the radio and television microwave transmitter.

[0004] Therefore, a heat dissipation device for a radio and television microwave transmitter is proposed to prevent moist air from entering the interior of the radio and television microwave transmitter. Utility Model Content

When the microwave launcher body 1 is in operation, the heat can be conducted outwards through the heat-conducting copper block 2. At the same time, by setting the cooling and heat dissipation component 6, the surface of the heat-conducting copper block 2 can be cooled, thereby dissipating the heat inside the microwave launcher body 1. At the same time, by setting the fan 7 and the ventilation component 8, the ventilation component 8 allows the air inside the connecting component 3 to circulate, and the fan 7 blows the heat inside the connecting component 3 outwards. The setting of the mounting base 10 can heat the microwave launcher body 1. 1 is installed and fixed on the TV tower. At this time, the microwave transmitter body 1 is arranged vertically. The setting of the block 9 can block external rainwater. At the same time, the air outlet of the ventilation component 8 is arranged downward, thereby preventing external rainwater from entering the interior of the connecting component 3 through the ventilation component 8. At this time, the heat dissipation treatment of the microwave transmitter body 1 can be completed. At the same time, there is no heat dissipation vent structure on the surface of the microwave transmitter body 1, which avoids the problem of moisture entering the interior of the microwave transmitter body 1 through the heat dissipation vent, and avoids the problem of internal components of the microwave transmitter body 1 being damaged by moisture.

[0027] like Figure 3 、 Figure 5 As shown, the cooling and heat dissipation component 6 includes a semiconductor refrigeration sheet 601, the bottom surface of the connecting block 5 is fixedly connected to the semiconductor refrigeration sheet 601, and the cooling surface of the semiconductor refrigeration sheet 601 is in contact with the heat-conducting copper block 2, and the bottom surface of the connecting block 5 is fixedly connected to the heat dissipation fins 602, and the heat dissipation fins 602 are in contact with the heat dissipation surface of the semiconductor refrigeration sheet 601; specifically, the setting of the cooling and heat dissipation component 6, after the connection cover 302 is installed, the cooling surface of the semiconductor refrigeration sheet 601 is in contact with the surface of the heat-conducting copper block 2, when the microwave launcher body 1 is in operation, the semiconductor refrigeration sheet 601 is in operation, and the heat-conducting copper block 2 generates heat on the internal components of the microwave launcher body 1 The heat is conducted, and at the same time, the semiconductor refrigeration sheet 601 cools the surface of the heat-conducting copper block 2, thereby cooling and dissipating the components inside the microwave launcher body 1. The heat dissipation fins 602 conduct the heat generated by the semiconductor refrigeration sheet 601. At the same time, the fan 7 is running, and the air flow blown by the fan 7 passes through the surface of the heat dissipation fins 602, and the heat is discharged to the outside of the connecting cover 302 through the ventilation component 8, thereby completing the cooling and heat dissipation of the microwave launcher body 1. At this time, when the microwave launcher body 1 dissipates heat, there is no need to dissipate heat by opening a heat dissipation port, so that the external humid air will not enter the interior of the microwave launcher body 1.

[0028] like Figure 3As shown, the ventilation component 8 includes an air inlet filter 801, the surface of the connecting cover 302 is provided with an air inlet filter 801, and the surface of the connecting cover 302 is provided with an air outlet filter 802; specifically, the setting of the ventilation component 8 blocks external dust so that dust does not enter the interior of the connecting cover 302, and the air inlet filter 801 allows the hot air inside the connecting cover 302 to be discharged outward through the blowing of the fan 7, and the setting of the air outlet filter 802 allows air flow to enter the interior of the connecting cover 302, which cooperates with the normal use of the fan 7.

The thermally conductive copper block 2 can also be symmetrically arranged on both sides of the microwave launcher body 1 in a rectangular shape, as long as the heat inside the microwave launcher body 1 can be conducted. The anti-corrosion paint can form a continuous protective film on the surface of the thermally conductive copper block 2, isolating the thermally conductive copper block 2 from corrosive substances in the external environment, preventing oxidation reactions and chemical erosion on the outer surface of the thermally conductive copper block 2, and thus can be used sustainably.

[0030] like Figure 4 As shown, there are two fans 7, and the two fans 7 are symmetrically distributed inside the connecting cover 302; specifically, the setting of the two fans 7, combined with the two groups of cooling and heat dissipation components 6 symmetrically arranged inside the connecting cover 302, can better cool and dissipate heat for the microwave transmitter body 1.

[0031] In summary, the heat dissipation device for a radio and television microwave transmitter is provided with a heat-conducting copper block 2 embedded in the surface of a microwave transmitter body 1. The heat-conducting copper block 2 fits in with the internal components of the microwave transmitter body 1. When installing the connecting component 3, the installing plug-in block 303 is aligned with the position of the slot 4 and inserted into the connecting cover 302. After the installing plug-in block 303 is plugged into the slot 4, the connecting cover 302 is sleeved on the outer surface of the microwave transmitter body 1. At the same time, the connecting cover 302 can be fixed to the outer surface of the microwave transmitter body 1 by installing the angle code 301.

When the microwave transmitter body 1 is in operation, the semiconductor refrigeration plate 601 is in operation, and the heat-conducting copper block 2 conducts the heat generated by the internal components of the microwave transmitter body 1. At the same time, the semiconductor refrigeration plate 601 The surface is cooled, and then the components inside the microwave launcher body 1 are cooled and dissipated. The heat dissipation fins 602 conduct the heat generated by the semiconductor refrigeration plate 601. At the same time, the fan 7 is running, and the air flow blown by the fan 7 passes through the surface of the heat dissipation fins 602, and the heat is discharged to the outside of the connection cover 302 through the air inlet filter 801. At this time, the microwave launcher body 1 can be heat-dissipated. At the same time, the microwave launcher body 1 does not need to open a heat dissipation port for heat dissipation. The installation of the mounting base 10 is used to install and fix the microwave launcher body 1. The microwave launcher body 1 is vertically installed and fixed on the TV tower. At this time, the setting of the block 9 can block rainwater, so that rainwater will not pass through the air outlet filter 802 to enter the interior of the connection cover 302.
