[0056] The following diagrams disclose various embodiments of this invention. For clarity, many practical details will be described in the following description. However, those skilled in the art will understand that these practical details are not essential in some embodiments of this invention and should not be used to limit the invention. Furthermore, for the sake of simplicity, some conventional structures and components are shown in a simplified schematic manner. Additionally, for ease of viewing, the dimensions of the components in the diagrams are not drawn to scale.

[0057] Figure 1 This is a front view of a water system control system 10 according to an embodiment of the present invention. Figure 2 for Figure 1 A partial three-dimensional view of area M of the water system control system 10. Figure 3 for Figure 2 A local decomposition diagram of region M. For example... Figures 1 to 3As shown, in this embodiment, the water circuit control system 10 includes a manifold assembly 100 and a movable valve 200. The manifold assembly 100 includes an external connection 110, a manifold node 120, a first manifold 130, and a second manifold 140. The external connection 110 includes an inlet 111 and an outlet 112, and the inlet 111 and outlet 112 are respectively coupled to a fluid source (not shown in the figure). The manifold node 120 connects to the external connection 110, the first manifold 130, and the second manifold 140. More specifically, the outer wall 121 of the manifold node 120 is recessed with a clearance channel 123, and the interior of the manifold node 120 has an inner chamber 122. The inner chamber 122 of the manifold node 120 is respectively connected to the outer part 110 (such as the inlet part 111 or the outlet part 112), the first manifold 130, the second manifold 140, and the clearance channel 123, so that the fluid from the fluid source (such as water, oil, or industrial coolant) can flow from the outer part 110 through the inner chamber 122 into the first manifold 130 and the second manifold 140 respectively. The first manifold 130 and the second manifold 140 are respectively used for heat dissipation of different components. Therefore, they may extend in different directions, for example, the extension direction of a part of the second manifold 140 is orthogonal to the extension direction of the first manifold 130; however, the invention is not limited to this. In addition, these first manifolds 130 are connected to multiple water-cooled plates 400, enabling the water-cooled plates 400 to cool fluids (such as water, oil, or industrial coolant).

[0058] Figure 4A for Figure 1 A partial sectional view along line segment AA. Figure 4B This is an operational diagram of the movable valve 200 in this embodiment, with its cross-sectional direction being parallel to... Figure 3 Same. For example... Figure 2 and Figure 4A As shown, the movable valve 200 includes a motor assembly 210 and a valve piston 230. The motor assembly 210 includes a motor body 211 and a screw 220. The motor body 211 is connected to the outer wall 121 of the manifold node 120. The screw 220 is synchronously driven with the rotor (not shown) of the motor body 211 and extends into the inner chamber 122 from the clearance channel 123. The motor assembly 210 may be, for example, a servo motor or a stepper motor, and the screw 220 may be, for example, a ball screw 220 or other screw 220; however, this invention is not limited to these.

[0059] like Figure 3 and Figure 4A As shown, the outer surface of the screw 220 is helically wound with an external thread 221. The valve piston 230 has a through channel 240, and the inner surface of the through channel 240 is helically wound with an internal thread 241. The internal thread 241 engages with the external thread 221, allowing the valve piston 230 to be reciprocally movable on the screw 220. Thus, as... Figures 4A to 4BAs shown, when the motor device 210 drives the screw 220 to rotate in one direction (such as clockwise), the valve piston 230 can move linearly towards the motor body 211 on the screw 220 due to the engagement of the internal thread 241 and the external thread 221; conversely, when the motor device 210 drives the screw 220 to rotate in the opposite direction (such as counterclockwise), the valve piston 230 can move linearly away from the motor body 211 on the screw 220 due to the engagement of the internal thread 241 and the external thread 221.

[0060] The valve piston 230 can be switched between the inner chamber 122 and the retraction channel 123 to selectively disconnect the connection between the outer part 110 and the first manifold 130 and the second manifold 140. More specifically, when the valve piston 230 moves linearly from the inner chamber 122 into the retraction channel 123, the valve piston 230 connects the outer part 110, the first manifold 130, and the second manifold 140 to each other, allowing fluid to flow smoothly from the outer part 110 into the first manifold 130 and the second manifold 140. Conversely, when the valve piston 230 moves linearly from the retraction channel 123 into the inner chamber 122, the valve piston 230 can fill the inner chamber 122 of the manifold node 120 and disconnect the connection between the outer part 110 and the first manifold 130 and the second manifold 140, thereby preventing fluid from continuing to flow into the first manifold 130 and the second manifold 140.

[0061] Furthermore, the valve piston 230 includes a piston rod 250 and a positioning part 260. A plurality of flexible washers 270 are wound around the outer peripheral surface of the piston rod 250. The positioning part 260 connects to the end of the piston rod 250 facing the motor body 211, and a through channel 240 radially penetrates both the piston rod 250 and the positioning part 260. The piston rod 250 and the positioning part 260 are integrally formed; however, this invention is not limited thereto.

[0062] Therefore, when the piston rod 250 extends into the inner chamber 122 of the manifold node 120, the soft washers 270 are directly compressed and abut against the inner surface of the inner chamber 122 of the manifold node 120, thereby effectively preventing fluid from seeping into the first manifold 130 and the second manifold 140. Conversely, when the piston rod 250 retracts into the clearance channel 123 of the manifold node 120, the soft washers 270 are directly compressed and abut against the inner surface of the clearance channel 123 of the manifold node 120, thereby effectively preventing fluid from seeping into the motor body 211.

[0063] For example, the positioning part 260 has a non-circular cross-section (such as a quadrilateral or hexagon, or other polygons), and the shape of the non-circular cross-section is the same as the shape of the clearance channel 123. Therefore, by limiting the positioning part 260 through the clearance channel 123, the valve piston 230 will not rotate when moving linearly on the screw 220. To prevent the valve piston 230 from being excessively moved and disengaging from the screw 220, the inner side of the clearance channel 123 facing the motor body 211 has a stop wall 123A. Figure 4B The stop wall 123A stops the continued movement of the positioning part 260, thereby preventing the valve piston 230 from disengaging from the screw 220.

[0064] The length of the screw 220 within the inner chamber 122 is not limited to Figure 4B The length shown is such that the length of the screw 220 in the inner chamber 122 is sufficient to allow the valve piston 230 to move into the inner chamber 122 and to allow the valve piston 230 to cut off the connection between the outer part 110 and the first manifold 130 and the second manifold 140.

[0065] In this embodiment, the manifold assembly 100 includes a support frame 125 and a leak sensor 310. The leak sensor 310 faces the first manifold 130 to sense whether the first manifold 130 is leaking. More specifically, the first connector 131 of the first manifold 130 is removably connected to the second connector 124 of the manifold node 120. The support frame 125 is connected to the outside of the manifold node 120 and is located directly below the first connector 131 and the second connector 124. The leak sensor 310 is located on the support frame 125 and between the first connector 131 and the support frame 125.

[0066] Thus, when the first connector 131 or the second connector 124 leaks liquid, the leak sensor 310 can send a sensing signal to the outside by sensing the falling water droplets, so that the water circuit control system 10 can take corresponding measures, such as having the motor device 210 cut off the connection between the external connector 110 and the first manifold 130 and / or the second manifold 140.

[0067] It should be understood that the rotor (not shown in the figure) of the motor body 211 is axially driven by the screw 220 to rotate, or radially driven by the screw 220 through a gear set (not shown in the figure). However, this invention is not limited to this.

[0068] Furthermore, in this embodiment, the manifold assembly 100 has a temperature sensor 320 located near the outlet 112 of the external connection 110 at the manifold node 120, so as to sense the fluid temperature of the fluid sent out by the first manifold 130 and / or the second manifold 140 respectively, thereby knowing the fluid temperature output from the outlet 112, so that the water circuit control system 10 can take corresponding measures, such as having the motor device 210 adjust the opening of the movable valve 200.

[0069] Thus, through the above architecture, the water circuit control system 10 of this invention can effectively and immediately control the flow rate or leakage of water, so as to precisely match the overall cooling plan of the liquid cooling heat dissipation mechanism.

[0070] Finally, the embodiments disclosed above are not intended to limit this invention. Any person skilled in the art may make various modifications and refinements without departing from the spirit and scope of this invention, and all such modifications and refinements shall be protected under this invention. Therefore, the scope of protection of this invention shall be determined by the appended claims.
