[0054] In order to make the description of the present invention more detailed and complete, reference can be made to the attached drawings and various embodiments described below, in which the same numbers represent the same or similar elements. On the other hand, well-known elements and steps are not described in the embodiments to avoid unnecessary limitations on the present invention.

[0055] In the embodiments and claims, unless the context specifically limits the article, "a", "an" and "the" may refer to one or more.

[0056] Please refer to Figure 1, which depicts a schematic diagram of the manifold liquid drainage system of the present invention. The manifold liquid drainage system 100 includes two parallel manifold liquid drainage devices 110, and a plurality of devices to be cooled 150 are arranged to be connected between the two manifold liquid drainage devices 110. A plurality of manifold assemblies 160 are installed on each manifold liquid drainage device 110. Each manifold assembly 160 includes a quick-disconnect connector 162, an electronic flow valve 180, a liquid sensor 166, and a temperature sensor 168, and a control circuit board 170 is used to control the flow of the individual manifold assembly 160 according to demand. For example, the manifold liquid drainage system 100 uses the control circuit board 170 to receive the sensing signals of the liquid sensor 166 and the temperature sensor 168 to control the electronic flow valve 180 to adjust the flow of the individual manifold assembly 160. The liquid sensor 166 can be a pressure sensor or a flow sensor, which is used to monitor the pressure or flow of the liquid in the manifold assembly 160. If the pressure or flow exceeds the preset range, the liquid sensor 166 will send the corresponding sensing signal (such as pressure or flow) to the control circuit board 170. The temperature sensor 168 monitors the temperature of the liquid in the manifold assembly 160. Similarly, if the temperature exceeds the preset range, the temperature sensor 168 will also send a sensing signal (such as temperature) to the control circuit board 170. The control circuit board 170 will calculate the flow signal based on the received sensing signal (such as pressure and temperature) and send it to the corresponding electronic flow valve 180. The electronic flow valve 180 adjusts the flow of the manifold assembly 160 according to the received sensing signal to keep it within the set pressure and temperature range. The manifold liquid discharge system 100 ensures that each manifold assembly 160 can operate under the best working conditions by continuously monitoring the pressure, flow or temperature of the liquid and adjusting the flow according to the actual situation.

[0057] Please also refer to Figure 2 , Figure 3 , Figure 4 , Figure 2 A three-dimensional diagram of a manifold liquid drainage device 110 included in the manifold liquid drainage system 100 of the present invention is shown. Figure 3 Draw Figure 2 An enlarged view of the top portion of the manifold liquid discharge device 110 (with the locking frame 113a removed), Figure 4 Draw Figure 2 FIG. 1 is an enlarged view of a single manifold assembly 160 of a manifold liquid discharge device 110. The manifold liquid discharge device 110 includes a liquid discharge body 114. The liquid discharge body 114 includes a hollow flow channel 114b and a plurality of openings 114a. Each opening 114a is equipped with a manifold assembly 160 to adjust the flow through the respective opening 114a according to actual conditions. Each manifold assembly 160 is connected to the hollow flow channel 114b through the corresponding opening 114a.

[0058] In some embodiments of the present invention, two manifold liquid discharge devices 110 are arranged vertically and in parallel to form a Figure 1 The configuration is that the two liquid discharge bodies 114 are arranged vertically and in parallel.

[0059] In some embodiments of the present invention, the top and bottom ends of the manifold liquid discharge device 110 include a locking frame ( 113 a , 113 b ) to securely lock the liquid discharge body 114 .

[0060] In some embodiments of the present invention, the manifold liquid discharge device 110 includes an exhaust valve 115. The exhaust valve 115 is located at the top of the liquid discharge body 114 and is connected to the hollow flow channel 114b. The main function of the exhaust valve 115 is to remove air or bubbles in the system. Air may exist in the manifold liquid discharge system 100, which will affect the cooling efficiency and cause system instability. The exhaust valve 115 can exhaust this air from the system, ensuring that the coolant can effectively flow throughout the system, thereby improving the cooling efficiency and performance of the system.

[0061] In some embodiments of the present invention, the manifold liquid discharge device 110 includes an inlet and outlet pipe 112. The inlet and outlet pipe 112 is connected to the hollow flow channel 114b of the liquid discharge body 114. The inlet and outlet pipe 112 can serve as a liquid inlet or a liquid outlet of the manifold liquid discharge device 110. When the inlet and outlet pipe 112 serves as a liquid inlet, the liquid is input into the liquid discharge body 114 from the inlet and outlet pipe 112, and is output from the liquid discharge body 114 by the multiple manifold components 160. When the inlet and outlet pipe 112 serves as a liquid outlet, the liquid is input into the liquid discharge body 114 from the multiple manifold components 160, and is output from the liquid discharge body 114 by the inlet and outlet pipe 112.

[0062] In some embodiments of the present invention, each manifold assembly 160 includes a tube body 161, a quick-release connector 162, a liquid leakage detector 164, an electronic flow valve 180, a liquid sensor 166, and a temperature sensor 168. The tube body 161 is assembled on the multiple openings 114a of the liquid discharge body 114 and connected to the hollow flow channel 114b. The quick-release connector 162 is used to provide a tube body connection for the cooling channel of the device to be cooled 150. The cooling channel of the device to be cooled 150 is connected to the manifold assembly of the two liquid discharge bodies 114. The electronic flow valve 180 is installed between the tube body 161 and the quick-release connector 162. The electronic flow valve 180 is used to adjust the liquid flow through the tube body 161 and the opening 114a. The liquid sensor 166 is installed on the first side of the tube 161, and the temperature sensor 168 is installed on the second side of the tube 161. The first side and the second side are two opposite sides of the tube 161. The liquid leakage detector 164 is located on the tube 161 to detect whether the tube 161 and / or the quick-release connector 162 is leaking.

[0063] In some embodiments of the present invention, the liquid leakage detector 164 can be a resistor or a capacitor. When a resistor is used, the leakage is usually detected based on the conductivity of the liquid. When the liquid touches the resistor, the resistance value changes, thereby triggering an alarm. When a capacitor is used, the presence of liquid is detected by measuring the change in the capacitance of the capacitor. When the liquid triggers the capacitor, its capacitance value changes, thereby triggering an alarm. Both methods can effectively detect water leaks, and the choice depends on the requirements and performance of the specific application.

[0064] In some embodiments of the present invention, when the liquid discharge body 114 is arranged vertically, the leakage detector 164 is disposed between two adjacent tubes 161 to detect whether the upper tube 161 of the two adjacent tubes 161 is leaking.

[0065] Please refer to Figure 5 , which illustrates a method 500 for operating a manifold liquid drainage system according to a first embodiment of the present invention. The method 500 is a method for operating a manifold liquid drainage system in response to a reading of a liquid sensor.

[0066] In step 502 of the method 500, the control circuit board 170 is used to read the pressure or flow readings of the liquid sensors 166 located in all the manifold assemblies 160. The liquid sensor 166 is used to read the pressure or flow readings of the liquid passing through the pipe body 161. The manifold assembly 160 in the first embodiment can be installed on the opening of the manifold liquid discharge device 110 upstream or downstream of the device 150 to be cooled.

[0067] In step 504 of method 500 , an average of the pressure or flow readings of all of the fluid sensors 166 is calculated using the control circuit board 170 .

[0068] In step 506 of method 500 , the pressure or flow reading of each fluid sensor 166 is compared to the average value calculated in step 504 using the control circuit board 170 .

[0069] In step 508 of the method 500 , when the pressure or flow reading of the liquid sensor 166 in a certain manifold assembly 160 is greater than the average value, the control circuit board 170 reduces the flow of the electronic flow valve 180 in the manifold assembly 160 .

[0070] In step 510 of the method 500 , when the pressure or flow reading of the liquid sensor 166 in a certain manifold assembly 160 is less than the average value, the control circuit board 170 increases the flow of the electronic flow valve 180 in the manifold assembly 160 .

[0071] In step 512 of the method 500 , when the pressure or flow reading of the liquid sensor 166 in a certain manifold assembly 160 is equal to the average value, the control circuit board 170 maintains the flow of the electronic flow valve 180 in the manifold assembly 160 .

[0072] Please refer to Figure 6 , which illustrates a method 600 for operating a manifold fluid drainage system according to a second embodiment of the present invention. The method 600 is a method for operating a manifold fluid drainage system in response to a reading of a temperature sensor.

[0073] In step 602 of method 600, the temperature readings of the temperature sensors 168 located in all manifold assemblies 160 are read using the control circuit board 170. The manifold assembly 160 in the second embodiment is mounted on the opening of the manifold liquid discharge device 110 downstream of the device 150 to be cooled.

[0074] In step 604 of the method 600, when the temperature reading of the temperature sensor 168 in a certain manifold assembly 160 is greater than a predetermined value, the control circuit board 170 increases the flow rate of the electronic flow valve 180 in the manifold assembly 160 and the corresponding manifold assembly 160. Because the temperature reading of the temperature sensor 168 located downstream of a certain device 150 to be cooled is too high, the flow rate of the electronic flow valve 180 upstream or downstream of the device 150 to be cooled is increased to reduce the operating temperature of the device 150 to be cooled.

[0075] In step 606 of the method 600, when the temperature reading of the temperature sensor 168 in a certain manifold assembly 160 is less than a predetermined temperature value, the control circuit board 170 reduces the flow of the electronic flow valve 180 in the manifold assembly 160 and the corresponding manifold assembly 160. Since the temperature reading of the temperature sensor 168 located downstream of a certain device 150 to be cooled is less than the predetermined value, the flow of the electronic flow valve 180 upstream or downstream of the device 150 to be cooled is reduced to save electricity.

[0076] In step 608 of the method 600 , when the temperature reading of the temperature sensor 168 in a manifold assembly 160 is equal to a predetermined temperature value, the control circuit board 170 maintains the flow rate in the manifold assembly 160 and the electronic flow valve 180 corresponding to the manifold assembly 160 .

[0077] Please refer to Figure 7 , which illustrates a method 700 for operating a manifold liquid drainage system according to a third embodiment of the present invention. The method 700 is a method for operating a manifold liquid drainage system in response to a risk of liquid leakage.

[0078] In step 702 of method 700 , a liquid leak detector 164 of a manifold assembly 160 detects a water leak.

[0079] In step 704 of method 700 , the pressure or flow reading of the liquid at the liquid sensor 166 of a manifold assembly 160 changes drastically, indicating a serious water leak condition.

[0080] In step 706 of the method 700 , the liquid leakage detector 164 sends a water leakage warning signal to the control circuit board 170 .

[0081] In step 708 of the method 700 , the control circuit board 170 closes the corresponding electronic flow valve 180 or closes the corresponding device to be cooled 150 .

[0082] The novel manifold liquid drainage system is equipped with a liquid sensor, a temperature sensor and a liquid leakage detector at each open manifold component, and uses a control circuit board to receive sensing signals from the liquid sensor and the temperature sensor to control the electronic flow valve to adjust the flow of the individual manifold components. The control circuit board also uses the liquid sensor and / or the liquid leakage detector to detect water leakage to prevent the water leakage from damaging the corresponding device to be cooled.
