Description

Technical Field

[0001] The present application relates to the field of circuit protection technology, and in particular to an over-temperature protection board for a high-efficiency thermal management HUB controller. Background Art

[0002] A HUB controller, also known as a USB HUB controller, is a device used to expand the problem of insufficient number of USB interfaces on a computer. It converts one USB interface into multiple USB interfaces, thereby expanding the computer's peripheral device connection capabilities. A HUB controller is usually integrated into a USB HUB device and has multiple USB ports. It can transfer data inserted into the USB port to multiple devices connected to the HUB controller, enabling simultaneous connection of multiple USB devices and sharing the same computer's broadband. In addition to providing interface expansion functions, modern HUB controllers have multiple other functions, such as supporting USB PowerDelivery technology, which can provide higher power for charging devices; supporting USB Type-C interfaces, which can achieve data transmission and power supply at the same time; supporting high-speed transmission protocols such as SUB 3.2 and Thunderbolt 3, which can provide faster data transmission speeds, etc.

[0003] Since the HUB controller integrates the above-mentioned multiple functions, the HUB controller may sometimes suffer performance degradation or even malfunction due to excessively high temperature. Currently, when the internal temperature of the HUB controller is too high, the HUB controller controls the temperature by adjusting the duty cycle of the PWM (pulse width modulation) signal. However, this method will reduce the working efficiency of the HUB controller and prevent the HUB controller from fully exerting its working efficiency.

[0004] The utility model provides an over-temperature protection board for a HUB controller with high efficiency thermal management. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide an efficient thermal management HUB controller over-temperature protection board to solve the problem in the above background technology that the HUB controller cannot exert its full working efficiency due to excessively high temperature during operation.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: an efficient thermal management HUB controller over-temperature protection board, including a shell and a circuit board installed inside the shell, a fan is installed on one side of the shell, and the circuit board is equipped with a USB interface electrically connected to the upstream device; multiple USB interfaces and multiple Type-C interfaces electrically connected to the downstream device; and a main control module, a power supply module and a temperature sensor electrically connected to the circuit board; and an over-temperature protection board for adjusting the heating components connected to the heating components on the circuit board, and the fan is electrically connected to the power supply module.

[0007] By adopting the above technical solution, in actual use, when the HUB controller is working, the heating components will generate heat. If the temperature inside the HUB controller is too high, the working efficiency of the HUB controller will be reduced to reduce the temperature of the HUB controller, which will make the HUB controller unable to perform all functions. The over-temperature protection board set on the circuit board of the HUB controller is in contact with the heating elements on the circuit board, so that the heat of the heating elements can be taken away, and the temperature sensor on the circuit board will feed back the monitored temperature to the main control module in real time. If the temperature reduction of the over-temperature protection board does not reach the preset threshold, the main control module will drive the power supply module electrically connected to it, and then the power supply module will start the fan electrically connected to it to work, so as to further reduce the temperature inside the HUB controller, so that when the temperature inside the HUB controller is too high, if the HUB controller wants to reduce the temperature, it needs to reduce the working efficiency of the HUB controller, so that the HUB controller can always work at full load efficiency.

[0008] A further optimized solution is that the over-temperature protection board includes a board body, a cooling pipe, a micro water pump and a bracket. The four glues of the board body are fixed with a bracket, the other end of the bracket is connected to the circuit board by bolts, and one side of the board body is in contact with the heating element on the circuit board, the cooling pipe is arranged inside the board body, the micro water pump is connected to the loop of the cooling pipe, and the power supply end of the micro water pump is electrically connected to the power supply module installed on the circuit board.

[0009] By adopting the above technical solution, the temperature of the part of the plate body that abuts the heating component of the circuit board is higher than the temperature of the part that does not abut the heating component of the circuit board. In order to allow the plate body to absorb heat quickly and evenly, thereby increasing the heat absorption capacity of the over-temperature protection plate, a cooling pipe and a water pump are arranged inside the plate body. After the power supply module drives the water pump to work, the cooling water in the cooling pipe will flow in the cooling pipe driven by the water pump, so that the plate body can quickly absorb the heat of the heating components on the circuit board, and the heat at the bottom of the plate body will also be quickly dissipated to the upper end of the plate body through the flowing coolant.

[0010] According to a further optimization scheme, a water flow channel is provided inside the plate body, a water collecting bottle is provided at the water outlet of the water flow channel, and the water collecting bottle is movably connected to the plate body.

[0011] By adopting the above technical solution, during actual use, if the cooling water in the cooling pipe leaks, it will flow onto the circuit board of the HUB controller, causing a short circuit on the circuit board and burning the electrical components on the circuit board, thereby affecting the working stability of the HUB controller. A water flow channel is provided inside the main body, and an opening on one side of the water flow channel is provided near the cooling pipe, and an opening on the other end is connected to a water collecting bottle. When the coolant in the cooling pipe leaks, it will flow into the water collecting bottle from the water flow channel, thereby preventing the coolant from flowing onto the circuit board and causing a short circuit or burning of the circuit board and electrical components, thereby ensuring the working stability of the HUB controller.

[0012] According to a further optimization scheme, a water level sensor is provided on the cooling pipe, and the water level sensor is electrically connected to the main control module.

[0013] By adopting the above technical solution, in order to timely understand the condition of the coolant in the cooling pipe, a water level sensor is installed in the cooling pipe. The water level sensor will monitor the condition of the antifreeze in the cooling pipe in real time and provide real-time feedback to the main control module.

[0014] According to a further optimized solution, the plate body is made of a heat-conducting material.

[0015] By adopting the above technical solution, the board body can quickly absorb the heat of the heating elements on the circuit board.

[0016] According to a further optimized solution, the cooling pipe is made of a heat-conducting material.

[0017] By adopting the above technical solution, the cooling pipe can quickly absorb the heat of the plate body and quickly dissipate the heat from the bottom end of the plate body to the top end of the plate body.

[0018] According to a further optimization scheme, a display screen for displaying temperature data and water level alarm information is provided on the top of the shell.

[0019] By adopting the above technical solution, the user can know the temperature inside the HUB controller at any time and know in time whether there is any leakage of coolant in the cooling pipe.

[0020] According to a further optimization scheme, a power interface for connecting to an external power source is provided on one side of the housing, and the power interface is electrically connected to the power supply module.

[0021] By adopting the above technical solution, the power supply source of the HUB controller is the device connected to the upstream USB interface. If the power supply is insufficient, the power interface can be used to connect an external power supply to ensure the stability of the HUB controller.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the over-temperature protection board and fan, the over-temperature protection board can quickly take away the temperature of the heating elements on the circuit board, and the temperature sensor will feed back the temperature data to the main control module in real time. If the temperature drop of the over-temperature protection board does not reach the preset threshold, the main control module will drive the power supply module electrically connected to it, and then the power supply module will start the fan electrically connected to it to further reduce the temperature inside the HUB controller, so that when the internal temperature of the HUB controller is too high, if the HUB controller wants to reduce the temperature, it needs to reduce the working efficiency of the HUB controller, thereby making the HUB controller always work at full load efficiency.

[0024] 2. By installing cooling pipes and water pumps inside the board, the board can absorb heat evenly, increasing the heat absorption effect of the board, thereby achieving the purpose of rapid cooling.

[0025] 3. The water flow channel and water collecting bottle set inside the main body can prevent the cooling water in the cooling pipe from leaking onto the circuit board, causing short circuit or burning of the circuit board or electronic components, thereby ensuring the stability of the HUB controller.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] Example, see Figure 1 , Figure 2 and Figure 3, an efficient thermal management HUB controller over-temperature protection board, includes a shell 1 and a circuit board 2 installed inside the shell, a fan 3 is installed on one side of the shell 1, and a main USB interface 4 electrically connected to an upstream device is installed on the circuit board 2; multiple secondary USB interfaces 5 and multiple Type-C interfaces electrically connected to downstream devices; a main control module 7, a power supply module 8 and a temperature sensor 9 electrically connected to the circuit board 2; and an over-temperature protection board for adjusting the heating components connected to the heating components on the circuit board 2, the fan 3 is electrically connected to the power supply module 8, the main control module 7 is electrically connected to the power supply module 8 through the circuit board 2, the main control module 7 is electrically connected to the temperature sensor 9 through the circuit board 2, and the voltage output end of the power supply module 8 is electrically connected to the temperature sensor 9 through the circuit board 2.

[0032] Specifically, the over-temperature protection board includes a board body 10, a cooling pipe 11, a micro water pump 12 and a bracket 13. The brackets 13 are fixed to the four corners of the board body 10. The other end of the bracket 13 is connected to the circuit board 2 by bolts, and one side of the board body 10 is abutted against the heating element on the circuit board 2. The cooling pipe 11 is installed inside the board body 10, the micro water pump 12 is connected to the loop of the cooling pipe 11, and the power supply end of the micro water pump 12 is electrically connected to the power supply module 8 installed on the circuit board 2.

[0033] More specifically, in order to prevent the cooling water in the cooling pipe 11 from leaking onto the circuit board 2 of the HUB controller, which would cause a short circuit in the circuit board 2 and burn the electrical components on the circuit board 2, thereby affecting the working stability of the HUB controller, a water flow channel is provided inside the body. One end opening of the water flow channel is provided near the cooling pipe 11, and the other end opening is connected to a water collecting bottle 14. The water collecting bottle 14 is movably connected to the opening of the plate body 10, or is connected by a thread.

[0034] In order to timely understand the condition of the coolant in the cooling pipe 11, a water level sensor 15 is installed on the cooling pipe 11. The water level sensor 15 is electrically connected to the main control module 7. The water level sensor 15 monitors the condition of the coolant in the cooling pipe 11 in real time and feeds back the coolant level data to the main control module 7 in real time.

[0035] In order to allow the over-temperature protection board to more effectively absorb the heat of the heating elements on the circuit board 2, the board body 10 and the cooling tube 11 are preferably made of aluminum material. Aluminum material has good heat absorption effect and is light in weight. While absorbing heat well, it reduces the weight of the HUB controller.

[0036] In order to facilitate the user to timely understand the internal temperature of the HUB controller and the coolant condition in the cooling pipe 11, a display screen 16 for displaying temperature data and water level alarm information is installed on the top of the housing 1.

[0037] The power supply of the HUB controller comes from the device of the upstream USB interface. If there are too many expansion devices connected to the HUB controller, it will cause insufficient power supply, thus affecting the stability of the HUB controller. In order to maintain the stability of the HUB controller, an external power supply interface 17 is provided on one side of the shell 1, and the power supply interface 17 is electrically connected to the power supply module 8.

[0038] In the specific implementation process, after the main USB interface 4 of the HUB controller is connected to the upstream device, the HUB controller starts to work, and the temperature of the heating component is cooled down by absorbing heat through the over-temperature protection plate. The temperature sensor 9 will monitor the temperature of the heating element in real time and feed back the temperature data to the main control module 7. The water level sensor 15 will monitor the condition of the coolant inside the cooling pipe 11 in real time and feed back the water level data to the main control module 7. The main control module 7 will display the information of both on the display screen 16 for the user to intuitively understand the temperature and water level conditions. If the temperature inside the HUB controller is higher than the preset threshold, the main control module 7 drives the power supply module 8, and the power supply module 8 starts the fan 3 and the micro water pump 12 to start working to cool down the temperature inside the HUB controller.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
