Description

Technical Field

[0001] This utility model relates to the field of water-cooling technology for vehicle controllers, and in particular to a water-cooling system connection valve and a water-cooling system. Background Technology

[0002] With the rapid development of new energy vehicle technology, the power density of on-board controllers is constantly increasing, placing higher demands on the cooling system. Water cooling, due to its high efficiency, uniform temperature distribution, and low noise, has become the mainstream cooling solution for high-power on-board controllers. In existing technologies, controller water cooling systems typically consist of components such as water pumps, radiators, water pipes, and valves. Among these, valves, as key control elements, are used to regulate coolant flow to achieve dynamic matching of cooling capacity.

[0003] Currently, vehicle-mounted water-cooling systems primarily use solenoid valves or mechanical valves as flow regulation devices. Solenoid valves control on / off flow by driving the valve core with an electromagnetic coil, offering fast response and high control precision. Mechanical valves, on the other hand, rely on temperature or pressure sensors for automatic regulation. Both types of valves require high-temperature resistance, corrosion resistance, and leak-proof properties, resulting in complex internal structures. Existing valve products generally use metal housings and precision-formed components, leading to high raw material costs and difficulties in assembly and installation space constraints. Furthermore, traditional valves typically weigh 300-500 grams, which adds to the overall vehicle weight and impacts range performance for lightweight new energy vehicles. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 As shown, the water cooling system connection valve provided in this embodiment of the present invention includes: a valve body 100, a valve core 200, and a plug cap 300; the valve core 200 is inserted into the valve body 100, the valve body 100 is provided with a first valve port 101 and a second valve port 102, the first valve port 101 and the second valve port 102 are spaced apart around the valve core 200; the valve core 200 is provided with a flow passage 201, and the valve core 200 rotates relative to the valve body 100 to realize the switching of open and closed states; in the open state, the first valve port 101 and the second valve port 102 are connected through the flow passage 201; in the closed state, the first valve port 101 and the second valve port 102 are both offset from the flow passage 201, so that the first valve port 101 and the second valve port 102 are separated; the plug cap 300 is connected to the valve core 200, and the plug cap 300 is connected to the valve body 100 by a snap-fit ​​connection.

[0024] Specifically, the valve housing 100 is an integral cylindrical shell component with an internal mounting cavity for accommodating the valve core 200. A first valve port 101 and a second valve port 102 are respectively provided on the side wall of the valve housing 100. The first valve port 101 and the second valve port 102 are circumferentially arranged around the periphery of the valve core 200 and spaced apart, preferably symmetrically distributed at 180° to facilitate linear flow channel communication. The first valve port 101 and the second valve port 102 are respectively used to connect one end of an external cooling pipe, for example, by using threaded connections, quick-connect fittings, or flanges to connect with other components. The valve core 200 is rotatably inserted into the mounting cavity of the valve housing 100, with its axis aligned with the central axis of the valve housing 100. The valve core 200 has a flow channel 201 penetrating a portion of its area. This flow channel 201 is arc-shaped or a straight through-hole in cross-section, with the specific shape designed according to the required flow characteristics. When the valve core 200 rotates relative to the valve housing 100, the position of the flow channel 201 changes accordingly, thereby switching the connection state between the first valve port 101 and the second valve port 102. In the open state, the user rotates the valve core 200 to a preset angle using the plug cap 300, aligning the flow channel 201 with both the first and second valve ports 101. Cooling medium can flow in from the first valve port 101 and out through the flow channel 201 to the second valve port 102, forming a smooth flow path. If the valve core 200 continues to rotate by a certain angle (e.g., 60° or 90°, depending on the design), the flow channel 201 will completely deviate from the positions of the first and second valve ports 101, i.e., both will be offset from the flow channel 201. At this point, the first and second valve ports 101 are blocked by the solid portion of the valve core 200 and cannot connect through the flow channel 201, thus effectively cutting off the fluid passage.

[0025] In this embodiment of the invention, the valve core 200 is provided with a first arcuate sidewall 210 and a second arcuate sidewall 220; the first arcuate sidewall 210 and the second arcuate sidewall 220 are coaxial and spaced apart circumferentially, forming a flow channel 201 between the first arcuate sidewall 210 and the second arcuate sidewall 220. This makes the valve core 200 structure simpler, lighter, and easier to process and mold using casting, injection molding, and other processes.

[0026] like Figure 1 and Figure 3As shown, a convex ring 103 is provided at the bottom of the inner cavity of the valve housing 100, and the convex ring 103 is supported between the first arcuate sidewall 210 and the second arcuate sidewall 220. By using the radial support of the convex ring 103 between the first arcuate sidewall 210 and the second arcuate sidewall 220, the first arcuate sidewall 210 and the second arcuate sidewall 220 can be tightly attached to the inner cavity sidewall of the valve housing 100, thereby ensuring that in the closed state, the first arcuate sidewall 210 and the second arcuate sidewall 220 can correspondingly and tightly seal the first valve port 101 and the second valve port 102. Furthermore, the support of the convex ring 103 strengthens the radial support of the valve core 200, reducing the material and structural strength requirements of the valve core 200 itself, which is beneficial for using lower-cost materials to produce the valve core 200, thereby saving manufacturing costs.

[0027] Furthermore, to improve the sealing effect, a first sealing ring 230 corresponding to the first valve port 101 is installed on the outer side of the first arc-shaped sidewall 210, and the first sealing ring 230 is pressed between the inner wall of the valve body 100 and the first arc-shaped sidewall 210; a second sealing ring 240 corresponding to the second valve port 102 is installed on the outer side of the second arc-shaped sidewall 220, and the second sealing ring 240 is pressed between the inner wall of the valve body 100 and the second arc-shaped sidewall 220. This ensures good sealing performance and prevents leakage in the closed state.

[0028] Furthermore, the first arcuate sidewall 210 is provided with a first limiting portion adapted to the first sealing ring 230, and the second arcuate sidewall 220 is provided with a second limiting portion adapted to the second sealing ring 240. Both the first and second limiting portions can be configured as annular grooves, with the first sealing ring 230 and the second sealing ring 240 respectively embedded within their corresponding annular grooves, thereby achieving positioning and installation of the first sealing ring 230 and the second sealing ring 240. Additionally, the first sealing ring 230 and the second sealing ring 240 can also be configured as protrusions respectively supported on the inner rings of the first sealing ring 230 and the second sealing ring 240, which similarly prevents the first sealing ring 230 and the second sealing ring 240 from loosening or shifting.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the valve housing 100 is provided with a retaining ring portion 104, and the plug cap 300 is provided with a first retaining claw 301 and a second retaining claw 302. The first retaining claw 301 and the second retaining claw 302 are arranged at intervals along the circumference of the retaining ring portion 104. The retaining ring portion 104 rotates around its own axis and engages between the first retaining claw 301 and the second retaining claw 302.

[0030] The first claw 301 and the second claw 302 are both provided with wedges or hooks that can be hooked onto the bottom of the retaining ring 104. When the first claw 301 and the second claw 302 are engaged to connect the retaining ring 104, the plug cap 300 can still rotate relative to the valve housing 100, thereby driving the valve core 200 to rotate.

[0031] like Figure 2 As shown, in an optional embodiment, the retaining ring portion 104 is provided with a notch portion 105 that adapts to the first retaining claw 301 or the second retaining claw 302. Alternatively, the retaining ring portion 104 may be provided with a notch portion 105 that can simultaneously adapt to the first retaining claw 301 and the second retaining claw 302. When at least one pair of the first retaining claw 301 and the second retaining claw 302 is aligned with the position of the notch portion 105, the plug cap 300 can be easily removed from the valve body 100, thereby reducing the difficulty of maintenance and disassembly.

[0032] like Figure 2 As shown, in an optional embodiment, a boss 400 is connected between the valve core 200 and the plug cap 300; when the plug cap 300 is engaged with the valve housing 100, the boss 400 abuts against the valve housing 100, thereby achieving axial installation limitation of the valve core 200, the plug cap 300 and the boss 400 relative to the valve housing 100. Furthermore, the boss 400 can cover the top opening of the valve housing 100, thereby preventing external dirt from seeping into the gap between the valve housing 100 and the valve core 200.

[0033] In an optional embodiment, the valve core 200, boss 400, and plug 300 are integrally formed using processes such as casting and injection molding, which helps reduce manufacturing costs. After the integral structure of the valve core 200, boss 400, and plug 300 is manufactured, the valve core 200 is inserted into the valve housing 100 by holding the plug 300. When the first claw 301 and the second claw 302 engage and connect to the retaining ring 104, the boss 400 fits precisely against the top surface of the valve housing 100, thus completing the rapid assembly of the water cooling system connection valve, greatly improving assembly efficiency and helping to save labor costs.

[0034] See Figure 4 The water cooling system provided in this embodiment of the utility model is equipped with the water cooling system connection valve described in the above embodiments. The water cooling system uses the water cooling system connection valve to regulate the cooling water flow of the controller housing 500, and has the same technical effect as the water cooling system connection valve, which will not be described again here.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
