Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circuit board cooling, in particular to a cooling protection mechanism for a TCON circuit board. Background Art
[0002] The logic board is also called the screen driver board, central control board, or TCON board. The function of the logic board is to convert the LVDS image data input signal (the input signal includes three types of signals: RGB data signal, clock signal, and control signal) sent by the digital board into an LVDS signal that can drive the LCD screen after being processed by the logic board, and then directly sent to the LVDS receiving chip of the LCD screen.
[0003] In the design of the circuit mainboard, in order to improve the heat dissipation capacity of the circuit mainboard, its high power consumption components such as power transistors, large-scale integrated circuits, etc. are arranged at the edge of the circuit mainboard as much as possible. The main control chip is often arranged in the middle of the circuit mainboard due to the need to take into account the wiring length. However, as the functions of existing circuit boards are increasing and the performance is becoming more and more powerful, the mainboard needs to be opened to install multiple chips. Multiple chips are usually installed in different positions for heat dissipation to avoid heat accumulation. At the same time, different chips are mobilized according to the work content, which may cause the actual heating position to change during work. The existing circuit board heat dissipation is usually carried out with the help of heat dissipation copper tubes, and the heat dissipation efficiency is insufficient. In view of this, we propose a cooling protection mechanism for TCON circuit boards. Utility Model Content
[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a temperature reduction protection mechanism for a TCON circuit board, which can solve the problem that the key heating parts cannot be centrally cooled.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling protection mechanism for a TCON circuit board, comprising a circulating plate, a groove is provided on the upper surface of the circulating plate, a circuit board is arranged inside the groove, two sliding grooves are provided on the upper surface of the circulating plate, the inner walls of the two sliding grooves are respectively fixedly connected with limiting sliding rods, a sliding plate is slidably connected to the upper surface of the circulating plate, a sliding block is fixedly connected to the lower surface of the sliding plate, the sliding block extends into the interior of the sliding groove and is slidably sleeved on the outer surface of the limiting sliding rod, a through groove communicating with the lower surface of the sliding plate is provided on the upper surface of the sliding plate, an exhaust fan is provided on the inner wall of the through groove, a rotating groove is provided on the inner wall of the groove, storage grooves are provided on the left and right sides of the rotating groove, and a cooling component is provided inside the rotating groove.
[0006] Preferably, the cooling component comprises a rotating tube, which is rotatably connected to the bottom wall of the rotating groove, an outer surface of the rotating tube is provided with an air outlet straight tube and a curved tube, and the interior of the circulating plate is arranged to be hollow.
[0007] Preferably, a through groove communicating with the interior of the circulation plate is formed on the lower surface of the circulation plate, an air inlet pipe is fixedly connected to the inner wall of the through groove, and a filter plate is fixedly connected to the inner wall of the air inlet pipe.
[0008] Preferably, an air inlet fan is provided on the inner wall of the air inlet pipe, and an air blowing pipe is fixedly connected to the inner wall of the groove, and the air blowing pipe is communicated with the interior of the circulating plate.
[0009] Preferably, the lower surface of the rotating tube is rotatably connected with an air supply pipe, and the air supply pipe is also communicated with the interior of the circulating plate.
[0010] Preferably, the rotating tube is communicated with the interior of the air supply tube, and a trigger adjustment rod is fixedly connected to the lower surface of the sliding plate.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] (1) The cooling protection mechanism for the TCON circuit board cools the circuit board by blowing cold air from the outside into the groove to cool the circuit board through the cooling component inside the rotating groove, and at the same time, the hot air inside the groove is extracted by the exhaust fan, thereby forming a circulation to improve air fluidity. At the same time, when the heating part is inconsistent with the position of the exhaust fan, the sliding plate can be pushed to move. When the sliding plate moves, its movement trajectory is limited by the sliding block and the limit slide bar. Through the above structure, when the circuit board is cooled, a circulation can be formed through the cooling component and the exhaust fan to improve air fluidity, so that cold air can quickly enter the interior of the groove and hot air can be quickly blown to the bottom of the exhaust fan and extracted, thereby avoiding the problem that the traditional copper tube heat dissipation position is fixed and it is difficult to cool the hot air.
[0013] (2) The temperature reduction protection mechanism for the TCON circuit board will synchronously drive the trigger adjustment rod to move when adjusting the position of the exhaust fan. When the trigger adjustment rod moves, it will contact the straight air outlet pipe and force the rotating pipe to rotate. After the rotating pipe rotates, it enters the interior of the storage groove. At this time, the bent pipe is turned out, and the bent pipe is used to change the air outlet trajectory of the inner walls on the front and rear sides of the groove. Therefore, at this time, the wind still flows in the direction of the exhaust fan, thereby avoiding the heat caused by the displacement of the exhaust fan not being concentrated under the exhaust fan and causing untimely discharge. Through the above structure, when the position of the exhaust fan is adjusted, the air outlet direction of the inner walls on the front and rear sides of the groove will also change accordingly, so that the hot air can always be blown to the bottom of the exhaust fan, thereby improving the exhaust efficiency of the exhaust fan and effectively avoiding heat accumulation of the circuit board.

When the position of the exhaust fan is adjusted, the trigger adjustment rod 20 will be driven to move synchronously. When the trigger adjustment rod 20 moves, it will contact the air outlet straight pipe 13 and force the rotating tube 12 to rotate.
