Description

Technical Field

[0001] The utility model relates to the technical field of audio equipment, in particular to an all-in-one central control conference system. Background Art

[0002] The conference system host can be connected to multiple microphones, allowing each microphone to produce sound through the speakers, making it suitable for large conference rooms with multiple people. When the conference system host is running, its built-in CPU and other components need to be cooled to maintain stable operation of the conference system host.

[0003] In the prior art, cooling of conference system hosts is often achieved through passive heat conduction using aluminum sheets, followed by fans to increase air flow. However, in certain high-power or high-load operating scenarios, the aluminum sheets may not provide adequate cooling, causing the host to overheat and affecting smooth operation. Heat dissipation components such as fans and aluminum sheets require regular cleaning and maintenance to ensure proper operation and cooling. Improper maintenance or untimely cleaning can lead to reduced cooling performance. Furthermore, the fans and aluminum sheets are located inside the host, making them difficult to clean. Utility Model Content

[0004] The purpose of the present invention is to provide an all-in-one central control conference system to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a central control conference system all-in-one machine, comprising a housing, a main control board installed inside the housing, and a connecting plug and a main control speaking rod provided on the front of the main control board;

[0006] The main control board has four RS232+RS485 dual-use composite interfaces and two RG45 network interfaces. The RS232+RS485 dual-use composite interfaces can customize the baud rate to control third-party sound, light, and electrical equipment. The RG45 network interface is used to connect to a switch or router. The main control board has a USB interface, two groups of 4-way RJ45 microphone unit interfaces, two 8-core microphone unit interfaces, a WIFI module, a 485 communication interface, and a 232 interface.

[0007] The main control board is provided with a plurality of heat conducting pipes, and the left and right ends of the heat conducting pipes are respectively connected to a liquid supply pipe and a liquid return pipe;

[0008] A liquid cooling radiator, the liquid cooling radiator being mounted on the side of the housing, with an air intake cavity being provided between the housing and the liquid cooling radiator, a plurality of fans being installed on the surface of the liquid cooling radiator, the liquid return pipe being connected to the liquid cooling radiator, and a liquid pump being provided between the liquid supply pipe and the liquid cooling radiator;

[0009] The liquid pump delivers the coolant into the heat pipe through the liquid supply pipe. After absorbing heat, the coolant returns to the liquid cooling radiator through the return pipe for cooling, which better dissipates heat for the main control board and ensures that the all-in-one machine will not lag when running under high load.

[0010] The dust cover is put on the surface of the liquid cooling radiator and the fan, and the dust cover fits the casing to prevent dust from adhering to the fan and the liquid cooling radiator, making cleaning easy.

[0011] Furthermore, a rectangular ring is provided on the side of the casing, and the rectangular ring is located on the side of the liquid cooling radiator. The surface of the rectangular ring is provided with several air inlet holes. The edge of the dust cover is provided with an elastic ring, and the elastic ring is sleeved on the surface of the rectangular ring, thereby improving the dust-proof effect of the dust cover on the fan and the liquid cooling radiator, and avoiding a large gap between the dust cover and the casing.

[0012] Furthermore, a thermal pad is provided on the surface of the heat pipe, and the thermal pad is attached to the heating element of the main control board to improve the heat conduction efficiency and ensure that the heat of the main control board can be quickly transferred to the heat pipe.

[0013] Furthermore, an IPS capacitive touch screen is installed on the surface of the casing, and the IPS capacitive touch screen is used to adjust parameters to facilitate the judgment of the temperature of the main control board.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The liquid pump draws the coolant from the liquid cooling radiator toward the heat pipe. The heat pipe is placed on the main control board to absorb the heat of the main control board. The heated coolant returns to the liquid cooling radiator. The fan dissipates heat from the liquid cooling radiator and the coolant, achieving rapid cooling of the main control board, improving the stability of the main control board under high load operation, and making it less prone to failure.

[0016] (2) The dust cover covers the fan and the liquid cooling radiator. The fan accelerates the air to pass through the liquid cooling radiator, cooling the liquid cooling radiator and the coolant. The dust cover prevents dust from adhering to the fan and the liquid cooling radiator, keeping the liquid cooling radiator from being blocked by dust. When cleaning the dust cover, you can directly remove the dust cover from the rectangular ring for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

The heat pipes 11 are in contact with components with large heat generation to dissipate heat from the components. The liquid supply pipe 9 and the liquid return pipe 12 form a circulating liquid path to achieve circulating heat dissipation.

[0062] Liquid-cooled radiator 8 is mounted on the side of the housing 2, and an air intake cavity is provided between the housing 2 and the liquid-cooled radiator 8. A plurality of fans 7 are installed on the surface of the liquid-cooled radiator 8. When the fans 7 rotate, air flows through the air intake cavity to the liquid-cooled radiator 8 and then takes away the heat dispersed by the liquid-cooled radiator 8. The return pipe 12 is connected to the liquid-cooled radiator 8. A liquid pump 14 is provided between the liquid supply pipe 9 and the liquid-cooled radiator 8. The liquid pump 14 maintains the flow of the coolant to prevent the coolant temperature from being too high, thereby providing better continuous heat dissipation for the main control board 13.

[0063] The dust cover 4 is put on the surface of the liquid cooling radiator 8 and the fan 7, and the dust cover 4 is in contact with the casing 2. The dust cover 4 is on the side of the casing 2, which is convenient for removal without affecting the appearance of the casing 2 too much. The dust cover 4 blocks dust and prevents dust accumulation on the fan 7 and the liquid cooling radiator 8. The dust cover 4 can be directly removed from the casing 2 for easy cleaning.

[0064] In this embodiment, if Figure 1 As shown, a mounting plate 1 is fixedly connected to the side of the housing 2. A fixing hole 3 is provided at the corner of the mounting plate 1. When the housing 2 needs to be fixed, screws can be used in conjunction with the fixing hole 3 to limit the sliding of the housing 2.

[0065] In this embodiment, if Figure 2 As shown, a rectangular ring 6 is provided on the side of the casing 2, and the rectangular ring 6 is located on the side of the liquid-cooled radiator 8. The surface of the rectangular ring 6 is provided with several air inlet holes. The rectangular ring 6 plays a role in fixing the dust cover 4. The air inlet holes allow the rectangular ring 6 to allow air to flow, and the air flow is not easily blocked, which has a good heat dissipation effect on the liquid-cooled radiator 8.

[0066] In this embodiment, if Figure 2 As shown, an elastic ring 5 is provided on the edge of the dust cover 4, and the elastic ring 5 is sleeved on the surface of the rectangular ring 6. The elastic ring 5 tightens the rectangular ring 6 to improve the stability of the connection between the dust cover 4 and the rectangular ring 6, and prevent the dust cover 4 from falling off accidentally.

[0067] In this embodiment, if Figure 4 As shown, a thermal pad 10 is provided on the surface of the heat pipe 11. The thermal pad 10 is attached to the heating element of the main control board 13.

[0068] In this embodiment, if Figure 4 As shown, an IPS capacitive touch screen 15 is installed on the surface of the housing 2. The IPS capacitive touch screen 15 is used to adjust parameters and can monitor the temperature of components in real time.

[0069] Specifically, when in use, after the main control board 13 is powered on and started, the liquid pump 14 and the fan 7 are started. The liquid pump 14 draws the coolant from the liquid-cooled radiator 8 and flows it along the liquid supply pipe 9 to the heat pipe 11. The components on the main control board 13 heat up, and the heat is transferred to the coolant in the heat pipe 11 to prevent the components from overheating. The heated coolant flows into the return pipe 12 and returns to the liquid-cooled radiator 8 along the return pipe 12. The liquid-cooled radiator 8 cools the coolant. The fan 7 accelerates the flow of air from the liquid-cooled radiator 8 to cool the liquid-cooled radiator 8, thereby cooling the coolant and then dissipating heat to the main control board 13.

[0070] The air drawn by the fan 7 is filtered by the dust cover 4 and then dissipates heat to the liquid cooling radiator 8, preventing most of the dust from adhering to the liquid cooling radiator 8 and the fan 7. After removing the dust cover 4 from the rectangular ring 6, the dust cover 4 can be cleaned, which is also convenient for cleaning the fan 7.
