Description

Technical Field

[0001] The utility model relates to the technical field of television signal receiving devices, in particular to a novel digital television signal receiving device with high anti-interference capability. Background Art

[0002] Digital television is an end-to-end system that processes signals digitally from program acquisition, program production, program transmission to the user end. In recent years, digital television has been widely used. The advantage of digital television is that it can transmit more programs to customers with relatively high transmission quality. Among them, digital television signal receiving devices are particularly important in the use of digital television.

[0003] When a digital TV signal receiving device is operating under high-intensity load, the temperature of the digital TV signal receiving device is too high. The digital TV signal receiving device may dynamically manage system components such as the CPU and GPU, causing the system components to experience frequency reduction protection. At this time, it will greatly interfere with the digital TV signal receiving device's reception of broadcast wireless signals, thereby affecting the use of digital TV. Therefore, we propose a new digital TV signal receiving device with high anti-interference performance. Utility Model Content

A heat-conducting component is provided above the plurality of legs 2, and the heat-conducting component is mounted by the legs 2 to facilitate the circulation of air inside the device housing 1. A PCBA board 3 is provided on the heat-conducting component. A radio frequency antenna 4 is detachably provided at the rear of the device housing 1. An upper heat dissipation component is provided above the device housing 1 to increase the space of the device housing 1, thereby quickly cooling the temperature of the device housing 1.

A side heat dissipation slot is provided on the left side of the device housing 1, and a side heat dissipation hole plate 7 is provided on the side heat dissipation slot. A left connecting frame 8 is provided on the right side of the side heat dissipation slot.

[0023] like Figure 3 、 4As shown in Figures 5 and 6, the upper heat dissipation component includes an annular cavity 9 opened above the device shell 1, an upper heat dissipation hole frame 10 is slidably connected in the annular cavity 9, a device shell cover 11 is provided above the upper heat dissipation hole frame 10, and supports are respectively provided on the left and right inner walls of the device shell 1. An electric push rod 12 is provided on the left support platform, and a telescopic rod 13 is provided on the right support platform. The upper ends of the electric push rod 12 and the telescopic rod 13 are respectively connected to the device shell cover 11, thereby increasing the space of the device shell 1, thereby quickly cooling the temperature of the device shell 1, thereby avoiding the electrical components on the PCBA board 3 from being in a high temperature state, which greatly interferes with the digital TV signal receiving device's reception of broadcast wireless signals.

[0024] like Figure 4 、 5 As shown, a temperature sensor 14 and a controller 15 are provided on the PCBA board 3. The temperature sensor 14 and the controller 15 are electrically connected to the electric push rod 12. The temperature near the PCBA board 3 is monitored in real time by the temperature sensor 14. When the temperature threshold is reached, the controller 15 receives the electrical signal from the temperature sensor 14, thereby controlling the operation of the electric push rod 12, causing the upper heat exhaust hole frame 10 to slide in the annular cavity 9 and the telescopic rod 13 to extend, thereby increasing the space of the device housing 1, thereby quickly cooling the device housing 1, thereby preventing the electrical components on the PCBA board 3 from being in a high temperature state, which would significantly interfere with the reception of broadcast wireless signals by the digital TV signal receiving device.

[0025] like Figure 3 、 4 As shown, the heat conducting assembly includes an upper heat conducting plate 16 that is in contact with the bottom of the PCBA board 3, and a plurality of side support plates 17 are respectively provided below the upper heat conducting plate 16.

The heat conducting assembly is made of copper, which effectively conducts heat to the PCBA board 3. Through the operation of the air exhaust 5, the wind is transported from the right connecting frame 6 to the "air duct", and then the air duct is cooled. Then, the hot air is discharged from the side heat dissipation slot through the left connecting frame 8, and the heat conducting machine assembly is efficiently cooled.

[0026] like Figure 3 、 4 As shown, an adapter air frame 19 is provided above the left connecting frame 8.

[0028] During the specific implementation of this embodiment, the heat-conducting component is erected by the support legs 2, thereby facilitating the circulation of air inside the device housing 1. The structural arrangement of the upper heat dissipation component increases the space of the device housing 1, thereby quickly cooling the temperature of the device housing 1. The temperature sensor 14 monitors the temperature near the PCBA board 3 in real time. When the temperature threshold is reached, the controller 15 receives the electrical signal of the temperature sensor 14, thereby controlling the operation of the electric push rod 12, causing the upper heat dissipation hole frame 10 to slide in the annular cavity 9, and the telescopic rod 13 to extend, thereby increasing the space of the device housing 1, thereby quickly cooling the temperature of the device housing 1, thereby preventing the electrical components on the PCBA board 3 from being in a high-temperature state and significantly interfering with the digital television signal receiving device to receive the broadcast wireless signal. To receive the signal, the bottom of the PCBA board 3 is heat-conducted through the heat-conducting component, and the air is transported from the right connecting frame 6 to the "air duct" through the operation of the air exhaust 5, thereby dissipating the heat in the air duct, and then the hot air is discharged from the side heat dissipation slot through the left connecting frame 8, efficiently dissipating the heat of the heat conduction machine component, and the air outlet of the adapter air frame 19 is directed to the electrical components on the PCBA board 3, and a part of the air transported by the right connecting frame 6 is guided to the vicinity of the electrical components on the PCBA board 3, thereby avoiding the electrical components on the PCBA board 3 from being in a high temperature state, which greatly interferes with the reception of broadcast wireless signals by the digital TV signal receiving device, and the device housing 1 is erected by the pads, so that the hot air inside the device housing 1 is discharged from the lower heat exhaust hole plate 20 on the lower heat dissipation slot.
