DETAILED DESCRIPTION

[0059] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0060] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0061] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0062] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0063] As people's living standards continue to improve, vehicles have become widely used as a means of transportation. Vehicles include multiple electrical appliances, such as the instrument panel, head unit, lights, power seats, audio equipment, and steering gear. They also include multiple thermal management actuators, such as water pumps, flow valves, fan motors, and air conditioning compressors. Currently, vehicles typically use batteries to power these appliances. Thermal management modules are also required to control these actuators.

[0064] In related technologies, batteries and thermal management modules are usually distributed in different positions of the vehicle. This not only requires separate installation structures for the batteries and thermal management modules, but also requires separate safety distances to be reserved for the batteries and thermal management modules to reduce the risk of contact between the batteries and thermal management modules and other components, resulting in a larger total space occupied by the batteries and thermal management modules. In addition, in order to protect the batteries and thermal management modules, it is usually necessary to separately configure housings for the batteries and thermal management modules, which increases the volume of the batteries and the thermal management modules, resulting in a further increase in the total space occupied by the batteries and thermal management modules, thereby significantly reducing the space utilization of the vehicle.

[0065] In order to improve the space utilization of the vehicle, the battery and thermal management module of the control device provided in the embodiment of the present application are housed in a box, so that the battery and thermal management module are integrated into a whole. Compared with the dispersed arrangement of the battery and thermal management module, not only is there no need to allocate assembly space separately for the battery and thermal management module, which effectively saves the assembly space of the control device, but there is also no need to configure a separate shell for the battery and thermal management module, which effectively reduces the volume of the control device and makes the overall structure of the control device more compact, thereby effectively improving the space utilization of the vehicle using the above-mentioned control device.

[0066] The control device provided in the embodiment of the present application can be applied to electrical equipment. The control device can be used to provide electrical energy to each electrical appliance in the electrical equipment, and can also be used to drive and control each thermal management actuator in the electrical equipment. The electrical equipment can be, but is not limited to, vehicles, portable devices, ships, spacecraft, electric toys, and electric tools, etc. The vehicle can be a fuel vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. The spacecraft includes airplanes, rockets, space shuttles, and spacecraft, etc. Electric toys include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Electric tools include metal cutting electric tools, grinding electric tools, assembly electric tools, and railway electric tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, etc.

[0073] The control device 100 provided in an embodiment of the present application is now described with reference to the accompanying drawings.

[0074] First, please refer to Figures 2, 3 and 6 together.

The battery 120 is used to be electrically connected to the electrical appliance 200, and the thermal management module 130 is used to be electrically connected to the thermal management actuator. The battery 120 and the thermal management module 130 are housed in the housing 110.

[0075] The housing 110 is a component for providing an internal environment for the control device 100, wherein the internal environment can be used to accommodate the battery 120, the thermal management module 130, and other functional components. The housing 110 can be an integrally formed component, and an opening 111 can be provided on the housing 110. The internal environment is connected to the external environment of the housing 110 through the opening 111, and the battery 120, the thermal management module 130, and other functional components can enter the internal environment through the opening 111.

Alternatively, the battery 120 may be constructed by first connecting multiple battery cells in series, in parallel, or in a hybrid configuration to form a battery module. The multiple battery modules may then be connected in series, in parallel, or in a hybrid configuration to form a single unit housed within the housing 110. Each battery cell can be a secondary battery or a primary battery. A secondary battery refers to a battery cell that can be recharged to activate the active material after the battery cell is discharged and can continue to be used.

[0079] In some embodiments, when vehicle 1000 is a new energy vehicle, vehicle 1000 includes a power battery, the power battery includes a liquid cooling device, the thermal management actuator in the liquid cooling device is a water pump, and the thermal management circuit is electrically connected to the water pump to control the operation of the water pump, thereby controlling the flow of coolant in the liquid cooling device, thereby achieving the purpose of regulating the temperature of the power battery.

[0081] In some other embodiments, vehicle 1000 includes a liquid cooling system, and the thermal management actuator in the liquid cooling system is a flow valve, which is arranged in a cooling pipe in the liquid cooling system. The thermal management circuit is electrically connected to the flow valve to change the flow rate of coolant in the cooling pipe by changing the opening of the flow valve, thereby achieving the purpose of regulating the temperature of the engine and power battery.

[0082] In some further embodiments, the vehicle 1000 includes an air conditioner, the thermal management actuator in the air conditioner is a compressor, and the thermal management circuit is electrically connected to the compressor to control the operation of the compressor, thereby achieving the purpose of regulating the cooling capacity or heating capacity of the air conditioner.

[0083] The control device 100 provided in the embodiment of the present application accommodates the battery 120 and the thermal management module 130 in the housing 110, so that the battery 120 and the thermal management module 130 are integrated into a whole. Compared with the manner in which the battery 120 and the thermal management module 130 are arranged in a dispersed manner, not only is there no need to allocate separate assembly space for the battery 120 and the thermal management module 130, which effectively saves the assembly space of the control device 100, but there is also no need to configure separate housings for the battery 120 and the thermal management module 130, which effectively reduces the volume of the control device 100, making the overall structure of the control device 100 more compact, thereby effectively improving the space utilization rate of the electrical equipment using the above-mentioned control device 100.

[0084] In some embodiments of the present application, referring to FIG. 3 , the box cover 140 includes a cover body 141 covering the open end of the box body 110 , and the cover body 141 is a metal member.

[0085] In other words, the cover 141 is made of metal material, which may be but not limited to aluminum, aluminum alloy, copper, iron, stainless steel, etc. The cover 141 may be an integrally formed component, that is, the cover 141 may be integrally formed by a die-casting process or a casting process.

[0086] By adopting the above technical solution, the heat inside the box body 110 can be quickly conducted outward through the cover body 141, thereby effectively improving the heat dissipation performance of the control device 100.

[0087] In some embodiments of the present application, the thermal management module 130 is thermally connected to the cover 141 .

[0088] It should be noted that the thermal management module 130 and the cover body 141 are thermally conductively connected, which means that the heat-generating part of the thermal management module 130 is in contact with the cover body 141, so that the heat generated by the heat-generating part of the thermal management module 130 is transferred to the cover body 141, thereby achieving the purpose of cooling the thermal management module 130.

[0089] In some embodiments, the top surface of the thermal management module 130 is arranged opposite to the bottom surface of the cover body 141, and the thermal management module 130 is thermally connected to the cover body 141, wherein the top surface of the thermal management module 130 refers to the surface of the thermal management module 130 facing away from the bottom of the box body 110, and the bottom surface of the cover body 141 refers to the surface of the cover body 141 facing the bottom of the box body 110.

[0090] By adopting the above technical solution, the heat generated by the operation of the thermal management module 130 can be quickly conducted outward through the cover body 141, thereby effectively improving the efficiency of cooling the thermal management module 130, and no additional cooling components are required, which effectively reduces the number of components of the control device 100 and the production cost of the control device 100, while further reducing the volume of the control device 100, thereby further improving the space utilization of the vehicle 1000 using the above control device 100.

[0091] In some embodiments of the present application, referring to FIG. 5 , a heat conducting portion 1411 is protruded from a surface of the cover 141 facing the box body 110 , and the thermal management module 130 is thermally connected to the heat conducting portion 1411 .

[0092] The heat conducting portion 1411 is a portion for contacting the heat-generating portion of the thermal management module 130. The number of heat conducting portions 1411 may be one or more, depending on the number of heat-generating portions of the thermal management module 130. The heat conducting portion 1411 may be, but is not limited to, a boss structure, a column structure, or a bump structure. The heat conducting portion 1411 has a contact surface for contacting the heat-generating portion of the thermal management module 130. The shape of the contact surface depends on the shape of the heat-generating portion of the thermal management module 130. For example, if the shape of the heat-generating portion of the thermal management module 130 is circular, the shape of the contact surface is also circular. In some embodiments, the top surface of the thermal management module 130 is arranged opposite to the heat conducting portion 1411, and the thermal management module 130 is thermally connected to the heat conducting portion 1411.

[0093] By adopting the above technical solution, the cover 141 can fully contact the thermal management module 130, thereby further improving the efficiency of cooling the thermal management module 130.

[0094] In some embodiments of the present application, please refer to Figures 3 and 4 together. The cover body 141 is provided with a wiring port (not shown in the figures), and the box cover 140 also includes an insulating member 142 arranged in the wiring port. The interior of the insulating member 142 is provided with a wiring channel 1421. The thermal management module 130 has a wiring head 133, and the wiring head 133 is passed through the wiring channel 1421.

[0095] The connection head 133 is used to electrically connect to the thermal management actuator. The number of the connection heads 133 can be multiple, depending on the actual application needs.

[0096] The wiring port connects the internal and external environments of the control device 100. The wiring connector 133 can extend outward through the wiring port to electrically connect the wiring connector 133 to the corresponding thermal management actuator via an electrical cable. There can be multiple wiring ports, depending on the number of wiring connectors 133.

[0097] The insulating member 142 is used to insulate and separate the terminal block 133 from the cover 141. It is understood that the insulating member 142 is made of an insulating material, which may include, but is not limited to, polypropylene, polyethylene, polyvinyl chloride, rubber, and the like. When the insulating member 142 is disposed within the wiring port, it covers the inner wall of the wiring port, and the wiring channel 1421 of the insulating member 142 passes through the bottom and top surfaces of the box cover 140. In other words, when the cover 141 is disposed over the open end of the box 110, the wiring channel 1421 of the insulating member 142 connects the internal environment of the control device 100 with the external environment.

[0098] In some embodiments, the top surface of the thermal management module 130 is arranged opposite to the bottom surface of the cover body 141, and the wiring head 133 of the thermal management module 130 is arranged on the top surface of the thermal management module 130, and the wiring head 133 of the thermal management module 130 is passed through the wiring channel 1421.

[0099] In some embodiments, there are multiple wiring ports, and accordingly, there are also multiple insulating members 142 . Multiple insulating members 142 are arranged one-to-one corresponding to multiple wiring ports. There are multiple wiring heads 133 , and the wiring heads 133 are inserted into the wiring channels 1421 of the corresponding insulating members 142 .

[0100] By adopting the above technical solution, the connection head 133 of the thermal management module 130 is effectively insulated and separated from the cover 141 , thereby effectively improving the reliability of the control device 100 .

[0101] In some embodiments of the present application, the insulating member 142 is injection molded in the connection port.

[0102] During the production of the control device 100 , the cover 141 may be first manufactured by a casting process, which may be, but is not limited to, a pouring process, a die-casting process, etc., and then the insulating member 142 may be formed in the wiring port by an injection molding process.

[0103] By adopting the above technical solution, the production process of the control device 100 is effectively simplified, thereby effectively improving the production efficiency of the control device 100.

[0104] Of course, in other embodiments, an injection molding process may also be used to form the insulating member 142 on the terminal block 133 of the thermal management module 130 .

[0105] In some embodiments of the present application, referring to FIG. 3 , the control device 100 further includes a heat insulating member 150 , which is disposed between the thermal management module 130 and the battery 120 .

[0106] The thermal insulator 150 is a component for isolating the heat transfer path between the thermal management module 130 and the battery 120. It is understandable that the thermal insulator 150 is made of a thermal insulation material, which may be, but is not limited to, fiberglass, asbestos, rock wool, silicate, etc.

[0107] In some embodiments, the thermal insulation member 150 has a plate-like structure. Taking the plate surface of the thermal insulation member 150 as the reference plane, the projection of the battery 120 in a direction perpendicular to the plate surface of the thermal insulation member 150 is located within the reference plane. In other words, the thermal insulation member 150 can completely cover the battery 120.

[0108] By adopting the above technical solution, the heat generated by the thermal management module 130 is effectively blocked from being transferred to the battery 120 , which effectively reduces the risk of thermal runaway of the battery 120 , thereby effectively improving the reliability of the control device 100 .

[0109] In some embodiments of the present application, referring to FIG3 , the thermal management module 130 , the thermal insulation member 150 , and the battery 120 are stacked sequentially along the depth direction of the housing 110 (the opposite direction of the Z direction as shown in FIG3 ).

[0110] By adopting the above technical solution, the thermal management module 130, the heat insulation component 150 and the battery 120 can make more full use of the internal space of the box 110, making the overall structure of the control device 100 more compact, thereby further improving the space utilization of the vehicle 1000 using the above control device 100.

[0111] In some embodiments of the present application, referring to FIG. 6 , the control device 100 further includes a cooling module 160 , and the thermal management module 130 is thermally connected to the cooling module 160 .

[0112] The cooling module 160 is a component for absorbing the heat generated by the operation of the thermal management module 130. The thermal connection between the thermal management module 130 and the cooling module 160 means that the thermal management module 130 is in contact with the cooling module 160, and the heat generated by the operation of the thermal management module 130 can be transferred to the cooling module 160 through the contact portion between the thermal management module 130 and the cooling module 160. Of course, in other embodiments, the cooling module 160 can also be thermally connected to other components of the control device 100 to cool the components. For example, the cooling module 160 can also be thermally connected to the battery 120. The cooling module 160 can be, but is not limited to, a liquid cooling module, an air cooling module, a metal thermal conductive module, etc. The cooling module 160 can be fixed in the box body 110 by a fixing structure. The fixing structure can be, but is not limited to, a fastening structure, a snap-fit ​​structure, an adhesive structure, etc.

[0113] By adopting the above technical solution, not only is it convenient to cool the thermal management module 130, but the battery 120, the thermal management module 130 and the cooling module 160 are also integrated into a whole, making the overall structure of the control device 100 more compact, thereby further improving the space utilization of the vehicle 1000 using the above control device 100.

[0114] In some embodiments of the present application, referring to FIG. 6 , the cooling module 160 is disposed between the thermal management module 130 and the battery 120 .

[0115] By adopting the above technical solution, not only is it convenient to cool the thermal management module 130, but it can also effectively prevent the heat generated by the thermal management module 130 from being transferred to the battery 120. It can also cool the battery 120 to a certain extent, effectively reducing the risk of thermal runaway of the battery 120, thereby effectively improving the reliability of the control device 100.

[0116] In some embodiments of the present application, referring to FIG. 6 , the thermal management module 130 , the cooling module 160 , and the battery 120 are stacked sequentially along the depth direction of the housing 110 (the opposite direction of the Z direction as shown in FIG. 6 ).

[0117] By adopting the above technical solution, the thermal management module 130, the cooling module 160 and the battery 120 can make more full use of the internal space of the box 110, making the overall structure of the control device 100 more compact, thereby further improving the space utilization of the vehicle 1000 using the above control device 100.

[0118] In some embodiments of the present application, the thermal management module 130 and the cooling module 160 are connected as one body.

[0119] The thermal management module 130 and the cooling module 160 may be connected in a manner including, but not limited to, fastening connection, bonding, welding, snap connection, and the like.

[0120] In some embodiments, a connecting seat is provided at the open end of the box body 110, and the number of the connecting seats can be multiple, and the multiple connecting seats are arranged at intervals along the circumference of the open end of the box body 110. The thermal management module 130 is connected to the cooling module 160 through fasteners. For example, the thermal management module 130 is connected to the side of the cooling module 160 facing the box cover 140 through fasteners, and the cooling module 160 is connected to the connecting seat 115 through fasteners.

[0121] By adopting the above technical solution, the thermal management module 130 and the cooling module 160 can be connected into a whole first, and then the whole can be assembled into the box 110, thereby effectively improving the assembly efficiency of the control device 100.

[0122] In some embodiments of the present application, referring to FIG7 , the cooling module 160 includes a liquid cooling plate 161 , a liquid inlet connector 162 and a liquid outlet connector 163 . A cooling channel (not shown) is provided inside the liquid cooling plate 161 . The thermal management module 130 is thermally connected to the liquid cooling plate 161 . The liquid inlet connector 162 is connected to the liquid inlet end of the cooling channel, and the liquid outlet connector 163 is connected to the liquid outlet end of the cooling channel.

[0123] In other words, in this embodiment, the cooling module 160 is a liquid cooling module.

[0124] Liquid cooling plate 161 is the main component of cooling module 160. It can be made of, but is not limited to, aluminum, aluminum alloy, copper, iron, stainless steel, etc. The cooling channel of liquid cooling plate 161 provides space for the flow of a cooling medium, which can be, but is not limited to, cooling water, cooling oil, etc.

[0125] Liquid inlet connector 162 is a component used to connect to an external liquid supply line and deliver cooling medium to the interior of the cooling channel. Liquid inlet connector 162 and liquid cooling plate 161 can be integrally formed components, i.e., liquid inlet connector 162 and liquid cooling plate 161 are integrally formed. Liquid inlet connector 162 and liquid cooling plate 161 can also be connected separately, for example, by welding them together.

[0126] Liquid outlet connector 163 is a component used to connect to an external drain line and output the cooling medium to the outside of the cooling channel. Liquid outlet connector 163 and liquid cooling plate 161 can be integrally formed components, that is, liquid outlet connector 163 and liquid cooling plate 161 are integrally formed. Liquid outlet connector 163 and liquid cooling plate 161 can also be connected separately, for example, liquid outlet connector 163 and liquid cooling plate 161 can be welded together to form a single piece.

[0127] By adopting the above technical solution, the efficiency of the cooling module 160 in cooling the thermal management module 130 is effectively improved, thereby effectively improving the reliability of the control device 100.

[0128] In some embodiments of the present application, please refer to Figures 6 to 8. The side wall of the box body 110 is provided with a first bayonet 112, and the inner edge of the first bayonet 112 is provided with a first sealing groove 114. The liquid inlet connector 162 includes a first sealing portion 1621 arranged in the first bayonet 112, and the outer peripheral side of the first sealing portion 1621 is convexly provided with a first rib 16211, and the first rib 16211 is inserted into the first sealing groove 114.

[0129] The first bayonet 112 is used to provide a mounting space for the liquid inlet connector 162. The shape of the first bayonet 112 can be, but is not limited to, circular, semicircular, square, trapezoidal, triangular, etc. The inner edge of the first bayonet 112 refers to the portion enclosing the inner space of the first bayonet 112.

[0130] The first sealing portion 1621 is used to seal the first bayonet 112. The outer contour of the first sealing portion 1621 is adapted to the shape of the first bayonet 112. For example, if the first bayonet 112 is semicircular, the outer contour of the first sealing portion 1621 is also semicircular. In some embodiments, the liquid inlet connector 162 may further include a first connecting portion 1622 and a second connecting portion 1623. The first sealing portion 1621 is connected between the first connecting portion 1622 and the second connecting portion 1623. The first connecting portion 1622 is connected to the external liquid supply pipeline, and the second connecting portion 1623 is connected to the liquid cooling plate 161.

[0131] In some embodiments, the first bayonet 112 is recessed in the open end of the box body 110. In other words, the first bayonet 112 passes through the open end of the box body 110 to form a first notch. This means that the first bayonet 112 can connect the internal environment of the box body 110 with the external environment along the thickness direction of the side wall of the box body 110 (the Y direction as shown in Figures 6 and 8). The first bayonet 112 can also connect the external environment of the box body 110 through the first notch. A first sealing groove 114 is recessed in the inner edge of the first bayonet 112. The first sealing groove 114 extends along the length of the inner edge of the first bayonet 112 and passes through both ends of the inner edge of the first bayonet 112. The first sealing portion 1621 can enter the first bayonet 112 through the first notch, and at the same time, the first rib 16211 enters the first sealing groove 114 until the first sealing portion 1621 is completely inserted into the first bayonet 112. At this time, the first rib 16211 cooperates with the first sealing groove 114 to seal the gap between the outer peripheral side of the first sealing portion 1621 and the inner edge of the first bayonet 112.

[0132] In other embodiments, the first bayonet 112 passes through the sidewall of the box body 110 but does not pass through the open end of the box body 110. In other words, the first bayonet 112 can only connect the internal environment of the box body 110 with the external environment along the thickness direction of the sidewall of the box body 110. The first sealing groove 114 is recessed in the inner edge of the first bayonet 112 and extends along the length direction of the inner edge of the first bayonet 112 to form a closed loop structure. The first rib 16211 forms a closed loop structure that surrounds the central axis of the liquid inlet connector 162. The outer diameter of the first rib 16211 is larger than the inner diameter of the first retaining plate 112. As the first sealing portion 1621 passes through the first retaining plate 112, the first rib 16211 is squeezed by the inner edge of the first retaining plate 112 until the first rib 16211 enters the first sealing groove 114. At this point, the first rib 16211 cooperates with the first sealing groove 114 to seal the gap between the outer periphery of the first sealing portion 1621 and the inner edge of the first retaining plate 112. In this embodiment, to facilitate entry of the first rib 16211 into the first sealing groove 114, the first rib 16211 can be made of a flexible material, such as, but not limited to, rubber or silicone. In other embodiments, the first sealing portion 1621 and the first rib 16211 can be integrally formed of a flexible material.

[0133] In some embodiments, in order to further improve the sealing performance of the control device 100 , the first sealing groove 114 may be filled with sealant.

[0134] By adopting the above technical solution, the liquid inlet connector 162 can be passed through the first bayonet 112 and the first bayonet 112 can be closed, thereby effectively improving the sealing performance of the control device 100. Moreover, there is no need to set up additional sealing parts to seal the first bayonet 112, thereby effectively simplifying the sealing structure of the control device 100 and the assembly process of the control device 100.

[0135] In some embodiments of the present application, please refer to Figure 8, a second rib 16212 and a third rib 16213 are convexly provided on the outer peripheral side of the first sealing portion 1621, and the second rib 16212, the first rib 16211 and the third rib 16213 are spaced apart along the length direction of the liquid inlet connector 162 (the Y direction as shown in Figure 8), the second rib 16212 abuts against the outer wall of the box body 110, and the third rib 16213 abuts against the inner wall of the box body 110.

[0136] It can be understood that when the first sealing portion 1621 is fully engaged with the first retaining groove 112, the second rib 16212 abuts against the outer wall of the case 110, and the third rib 16213 abuts against the inner wall of the case 110. In other words, the outer diameter of the second rib 16212 is larger than the diameter of the first retaining groove 112, and the outer diameter of the third rib 16213 is larger than the diameter of the first retaining groove 112. The spacing between the second rib 16212 and the third rib 16213 along the length of the liquid inlet connector 162 is equal to the thickness of the sidewall of the case 110. Of course, to account for assembly tolerances, a slight gap may exist between the second rib 16212 and the outer wall of the case 110, and similarly, a slight gap may exist between the third rib 16213 and the inner wall of the case 110.

[0137] In this embodiment, the first bayonet 112 passes through the open end of the box body 110 to form a first notch, and the first sealing groove 114 is recessed in the inner edge of the first bayonet 112. The first sealing groove 114 extends along the length direction of the inner edge of the first bayonet 112, and the first sealing groove 114 passes through both ends of the inner edge of the first bayonet 112. The first sealing portion 1621 can enter the first bayonet 112 through the first notch, and at the same time, the first rib 16211 enters the first sealing groove 114, the second rib 16212 abuts against the outer wall of the box body 110, and the third rib 16213 abuts against the inner wall of the box body 110 until the first sealing portion 1621 is completely inserted into the first bayonet 112. At this time, the first rib 16211 cooperates with the first sealing groove 114 to block the gap between the outer peripheral side of the first sealing portion 1621 and the inner edge of the first bayonet 112, the second rib 16212 blocks the gap between the outer peripheral side of the first sealing portion 1621 and the edge of one port of the first bayonet 112, and the third rib 16213 blocks the gap between the outer peripheral side of the first sealing portion 1621 and the edge of the other port of the first bayonet 112.

[0138] By adopting the above technical solution, the sealing performance of the control device 100 is further improved.

[0139] In some embodiments of the present application, please refer to Figures 6 and 7 together. A second bayonet 113 is opened on the side wall of the box body 110, and a second sealing groove is provided on the inner edge of the second bayonet 113 (not shown in the figure, refer to the structure of the first sealing groove 114 shown in Figure 8). The liquid outlet connector 163 includes a second sealing portion 1631 arranged in the second bayonet 113, and a fourth rib is convexly provided on the outer peripheral side of the second sealing portion 1631 (not shown in the figure, refer to the structure of the first rib 16211 shown in Figure 8), and the fourth rib is inserted into the second sealing groove.

[0140] The second bayonet 113 is used to provide a mounting space for the liquid outlet connector 163. The shape of the second bayonet 113 can be, but is not limited to, circular, semicircular, square, trapezoidal, triangular, etc. The inner edge of the second bayonet 113 refers to the portion enclosing the inner space of the second bayonet 113.

[0141] The second sealing portion 1631 is used to seal the second bayonet 113. The outer contour of the second sealing portion 1631 is adapted to the shape of the second bayonet 113. For example, if the second bayonet 113 is semicircular, the outer contour of the second sealing portion 1631 is also semicircular. In some embodiments, the liquid outlet connector 163 may further include a third connecting portion 1632 and a fourth connecting portion 1633. The second sealing portion 1631 is connected between the third connecting portion 1632 and the fourth connecting portion 1633. The third connecting portion 1632 is connected to the external drain pipe, and the fourth connecting portion 1633 is connected to the liquid cooling plate 161.

[0142] In some embodiments, the second bayonet 113 is recessed into the open end of the housing 110. In other words, the second bayonet 113 extends through the open end of the housing 110 to form a second notch. This allows the second bayonet 113 to connect the interior and exterior environments of the housing 110 along the thickness of the sidewall of the housing 110, and also allows the second bayonet 113 to connect to the exterior environment of the housing 110 through the second notch. A second sealing groove is recessed into the inner edge of the second bayonet 113, extending along the length of the inner edge of the second bayonet 113 and extending through both ends of the inner edge of the second bayonet 113. The second sealing portion 1631 can enter the second bayonet 113 through the second notch, while the fourth rib simultaneously enters the second sealing groove until the second sealing portion 1631 is fully engaged with the second bayonet 113. At this point, the fourth rib and the second sealing groove cooperate to seal the gap between the outer periphery of the second sealing portion 1631 and the inner edge of the second bayonet 113.

[0143] In other embodiments, the second bayonet 113 penetrates the sidewall of the housing 110 but does not penetrate the open end of the housing 110. In other words, the second bayonet 113 can only connect the internal environment of the housing 110 with the external environment along the thickness direction of the sidewall of the housing 110. A second sealing groove is recessed in the inner edge of the second bayonet 113 and extends along the length of the inner edge of the second bayonet 113 to form a closed loop structure. The fourth rib is a closed loop structure that surrounds the central axis of the liquid outlet connector 163. The outer diameter of the fourth rib is larger than the inner diameter of the second bayonet 113. As the second sealing portion 1631 passes through the second bayonet 113, the fourth rib is squeezed by the inner edge of the second bayonet 113 until the fourth rib enters the second sealing groove. At this point, the fourth rib cooperates with the second sealing groove to seal the gap between the outer periphery of the second sealing portion 1631 and the inner edge of the second bayonet 113. In this embodiment, to facilitate the fourth rib to enter the second sealing groove, the fourth rib can be made of a flexible material, which can be, but is not limited to, rubber, silicone, etc. Of course, in other embodiments, the second sealing portion 1631 and the fourth rib can be integrally formed of a flexible material.

[0144] In some embodiments, in order to further improve the sealing performance of the control device 100 , the second sealing groove may be filled with sealant.

[0145] By adopting the above technical solution, the liquid outlet connector 163 can be passed through the second bayonet 113 and the second bayonet 113 can be closed, thereby effectively improving the sealing performance of the control device 100. Moreover, there is no need to set up additional sealing parts to seal the second bayonet 113, which effectively simplifies the sealing structure of the control device 100 and the assembly process of the control device 100.

[0146] In some embodiments of the present application, a fifth rib (not shown in the figure, refer to the structure of the second rib 16212 shown in Figure 8 ) and a sixth rib (not shown in the figure, refer to the structure of the third rib 16213 shown in Figure 8 ) are convexly provided on the outer peripheral side of the second sealing portion 1631. The fifth rib, the fourth rib and the sixth rib are spaced apart along the length direction of the liquid outlet connector 163 (the Y direction as shown in Figure 8 ), and the fifth rib abuts against the outer wall of the box body 110, and the sixth rib abuts against the inner wall of the box body 110.

[0147] It can be understood that when the second sealing portion 1631 is fully engaged with the second retaining groove 113, the fifth rib abuts against the outer wall of the case 110, and the sixth rib abuts against the inner wall of the case 110. In other words, the outer diameter of the fifth rib is greater than the diameter of the second retaining groove 113, and the outer diameter of the sixth rib is greater than the diameter of the second retaining groove 113. The spacing between the fifth and sixth ribs along the length of the liquid outlet connector 163 is equal to the thickness of the sidewall of the case 110. Of course, to account for assembly tolerances, a slight gap may exist between the fifth rib and the outer wall of the case 110, and similarly, a slight gap may exist between the sixth rib and the inner wall of the case 110.

[0148] In this embodiment, the second bayonet 113 passes through the open end of the box body 110 to form a second notch, and the second sealing groove is recessed in the inner edge of the second bayonet 113. The second sealing groove extends along the length direction of the inner edge of the second bayonet 113, and the second sealing groove passes through both ends of the inner edge of the second bayonet 113. The second sealing portion 1631 can enter the second bayonet 113 through the second notch, and at the same time the fourth rib enters the second sealing groove, the fifth rib rests against the outer wall of the box body 110, and the sixth rib rests against the inner wall of the box body 110, until the second sealing portion 1631 is completely inserted into the second bayonet 113. At this time, the fourth rib cooperates with the second sealing groove to block the gap between the outer peripheral side of the second sealing portion 1631 and the inner edge of the second bayonet 113, the fifth rib blocks the gap between the outer peripheral side of the second sealing portion 1631 and the edge of one port of the second bayonet 113, and the sixth rib blocks the gap between the outer peripheral side of the second sealing portion 1631 and the edge of the other port of the second bayonet 113.

[0149] By adopting the above technical solution, the sealing performance of the control device 100 is further improved.

[0150] In some embodiments of the present application, please refer to Figure 8, an annular rib 143 is protruded from the side of the box cover 140 facing the box body 110, and a third sealing groove (not shown in the figure) extending along the circumference of the opening end is formed at the open end of the box body 110, and the annular rib 143 is inserted into the third sealing groove.

[0151] The annular rib 143 protrudes from the side of the box cover 140 facing the box body 110 along the covering direction of the box cover 140 and the box body 110 (the opposite direction of the Z direction as shown in Figure 8). Correspondingly, the third sealing groove is recessed at the edge of the open end of the box body 110 along the covering direction of the box cover 140 and the box body 110. When the box cover 140 is covered on the open end of the box body 110, the annular rib 143 is inserted into the third sealing groove.

[0152] By adopting the above technical solution, the gap between the box cover 140 and the box body 110 is effectively sealed, thereby effectively improving the sealing performance of the control device 100.

[0153] In some embodiments of the present application, please refer to Figures 6 to 8 together. The open end is provided with a first bayonet 112 and a second bayonet 113. The liquid inlet joint 162 includes a first sealing portion 1621 arranged in the first bayonet 112, and the first sealing portion 1621 is provided with a fourth sealing groove 16214. The liquid outlet joint 163 includes a second sealing portion 1631 arranged in the second bayonet 113, and the second sealing portion 1631 is provided with a fifth sealing groove (not shown in the figure, refer to the structure of the fourth sealing groove 16214 shown in Figure 8). The third sealing groove, the fourth sealing groove 16214 and the fifth sealing groove are connected to form an annular groove, and the annular rib 143 is inserted into the annular groove.

[0154] In this embodiment, the first bayonet 112 extends through the open end of the housing 110 to form a first notch, and the second bayonet 113 extends through the open end of the housing 110 to form a second notch. A fourth sealing groove 16214 is recessed on the side of the first sealing portion 1621 facing the first notch, and a fifth sealing groove is recessed on the side of the second sealing portion 1631 facing the second notch. When the first sealing portion 1621 is disposed within the first bayonet 112 and the second sealing portion 1631 is disposed within the second bayonet 113, the third, fourth, and fifth sealing grooves communicate to form an annular groove. The shape of the annular groove matches that of the annular rib 143. For example, if the annular rib 143 is square, the annular groove also has a square shape. When the housing cover 140 is disposed over the open end of the housing 110, the annular rib 143 is inserted into the annular groove.

[0155] By adopting the above technical solution, not only the gap between the box cover 140 and the box body 110 can be closed, but also the first bayonet 112 and the second bayonet 113 can be closed, thereby effectively improving the sealing performance of the control device 100. Moreover, there is no need to set up additional sealing parts to seal the first bayonet 112 and the second bayonet 113, thereby effectively simplifying the sealing structure of the control device 100 and the assembly process of the control device 100.
