DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor fall within the protection scope of the present application.

[0049] The present application provides a liquid cooling assembly 100, please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of the liquid cooling assembly 100 provided in the exemplary embodiments of the present disclosure, Figure 2 is a partial structural schematic diagram of the liquid cooling assembly 100 provided in the exemplary embodiments of the present disclosure. The liquid cooling assembly 100 comprises an expansion tank 110 and a water pump 120.

[0050] It should be noted that the expansion tank 110 has multiple functions, for example, in a closed circulation system, due to the increase in liquid temperature, the volume of the liquid in the system will increase due to the principle of thermal expansion and contraction. The expansion tank 110 can accommodate the amount of liquid that expands due to heating, thereby avoiding damage to the system due to excessive water pressure inside the system. When the system loses water due to some reason (such as evaporation, leakage, etc.), the expansion tank 110 can automatically supplement the required amount of water for the system, thereby ensuring the normal operation of the system.

[0051] Referring to Figure 1 and Figure 2 , the expansion tank 110 comprises a tank body 111 and a cover body 112, the tank body 111 is provided with a filling opening, and the cover body 112 is movably installed between the tank body 111 in an open position and a closed position. When in the open position, the cover body 112 is adapted to open the filling opening, and when in the closed position, the cover body 112 closes the filling opening.

[0052] Since the cover 112 can move between the open position and the closed position, this design enables the water tank to open or close the filling port as needed, thereby adapting to different operating requirements. For example, when the system needs to be replenished with water or to be vented, this can be achieved by opening the cover 112. When the cover 112 is in the closed position, the cover 112 can tightly close the filling port, preventing the leakage of cooling liquid and the entry of external impurities into the tank 111. The movable installation of the cover 112 makes the maintenance of the water tank more convenient. For example, when checking the liquid level inside the water tank, cleaning the water tank, or replacing the cooling liquid, the cover 112 can be easily opened.

[0053] It should be noted that in an embodiment, the cover 112 can be switched between the open position and the closed position by rotating the cover 112. In other embodiments, the cover 112 can also be switched between the open position and the closed position by pulling the cover 112 in the direction of the filling port. Specifically, the present application does not limit this.

[0054] The water pump 120 is arranged in series with the tank 111.

[0055] It should be noted that the main function of the water pump 120 is to pump the liquid in the tank 111 out and output it to other parts of the system. On the one hand, this design ensures that the liquid in the tank 111 can be continuously and stably supplied to the system. On the other hand, it can prevent the liquid in the tank 111 from being sprayed out of the filling port when the cover 112 is in the open position.

[0056] The liquid cooling assembly 100 of the present embodiment, when the cover 112 is in the open position, the water pump 120 starts to work and pumps the liquid in the expansion water tank 110 out. On the one hand, this design can prevent the liquid in the tank 111 from being sprayed out of the filling port when the cover 112 is switched from the open position, thereby improving the user experience. This design reduces the requirements of the expansion water tank 110 for the installation position, so that the expansion water tank 110 can be arranged at a position that is convenient for filling, thereby reducing the labor hours and costs, and also improving the maintenance convenience of the electrical equipment. On the other hand, the water pump 120 pumps the liquid in the expansion water tank 110 out and outputs it to other parts of the liquid cooling system, which ensures the continuous operation of the system and the effective circulation of the liquid. In addition, the working state of the water pump 120 is associated with the position of the cover 112, so that the working state of the water pump 120 can be controlled while the position state of the cover 112 is changed, thereby simplifying the operation.

[0057] Reference Figure 1 and Figure 2In some embodiments, the liquid cooling assembly 100 further comprises a switch assembly, which is arranged in series with the water pump 120, meaning that the start and stop of the water pump 120 will be directly controlled by the switch assembly. The switch assembly has an electrically connected state and an electrically disconnected state, which respectively correspond to the start and stop of the water pump 120. When the cover 112 is switched to the open position, the switch assembly is driven to switch from the electrically disconnected state to the electrically connected state, thereby starting the water pump 120 to work. When the cover 112 is switched to the closed position, the switch assembly is driven to switch from the electrically connected state to the electrically disconnected state, thereby stopping the water pump 120 from working. Since the position change of the cover 112 directly drives the state switching of the switch assembly, this design not only improves the automation level of the liquid cooling assembly 100, but also reduces the need for manual intervention. At the same time, since the position change of the cover 112 is intuitive, it is also convenient for users to observe and judge the running state of the water pump 120. Through the control of the switch assembly, the liquid cooling assembly 100 can ensure that the cover 112 is in the open state when the water pump 120 is working, thereby avoiding the problem of liquid spouting from the liquid self-filling port due to the opening of the cover 112. This design improves the safety of the liquid cooling assembly 100. When the cover 112 is in the closed position, the switch assembly automatically cuts off the power supply of the water pump 120, thereby avoiding unnecessary energy consumption. This design not only reduces the operating cost of the liquid cooling assembly 100, but also meets the current energy-saving and emission-reducing concept. Users only need to operate the cover 112 to control the water pump 120, without the need for additional operation steps or complex control logic, which makes the use of the liquid cooling assembly 100 more convenient.

[0058] It should be noted that in other embodiments, it may be necessary to make the water pump 120 work when the cover 112 is in the closed position to promote the liquid output of the liquid in the tank 111, and the water pump 120 is controlled to operate by another set of power supply lines of the whole vehicle.

[0059] Referring to Figure 2 In some embodiments, the switch assembly comprises a control switch 131 and a relay 132, the control switch 131 and the relay 132 are connected in series to form a control circuit a, and the control switch 131 is drivingly connected with the cover 112, the relay 132 and the water pump 120 are connected in series to form a power supply circuit b, and the power supply circuit b is arranged in parallel with the control circuit a. This design enables the control circuit a to control the on-off of the power supply circuit b, thereby realizing the start and stop control of the water pump 120. The cover 112 is drivingly connected with the control switch 131, which means that the position change of the cover 112 will directly drive the state change of the control switch 131. This design simplifies the control logic of the liquid cooling assembly 100 and improves the automation level of the liquid cooling assembly 100.

[0060] It should be noted that the liquid cooling assembly 100 further comprises a control power supply 170, the control power supply 170, the relay 132 and the control switch 131 are connected in series, so that when the control switch 131 is connected, the power supply 180 can supply power to the relay 132 so that the relay 132 is powered on. When the control switch 131 is disconnected, the power supply 180 stops supplying power to the relay 132, so that the relay 132 is powered off.

[0061] Specifically, in some embodiments, when the cover 112 is switched to the open position, the cover 112 drives the control switch 131 to be disconnected, so that the corresponding relay 132 is powered off, and the power supply circuit b is turned on. When the cover 112 is switched to the closed position, the cover 112 drives the control switch 131 to be connected, so that the relay 132 is powered on, and the power supply circuit b is turned off. In this way, when the cover 112 is switched to the open position, even if the control switch 131 is disconnected, the power supply circuit b can be kept on, so that the water pump 120 can work normally. When the cover 112 is switched to the closed position, the control switch 131 is connected, so that the power supply circuit b is turned off, so that the water pump 120 can stop working, which is simple in structure and easy to operate.

[0062] It should be noted that in this embodiment, the relay 132 can be a normally closed relay 132. The normally closed relay 132 (also known as NC relay 132) is in a closed state when it is not powered (powered off). This means that when the relay 132 does not receive an electrical signal, the circuit it controls is on. Conversely, when the relay 132 is powered on (powered on), its contacts open, thereby breaking the circuit.

[0063] Specifically, in some embodiments, when the cover 112 is switched to the open position, the cover 112 drives the control switch 131 to be connected, so that the relay 132 is powered on, and the power supply circuit b is turned on. When the cover 112 is switched to the closed position, the cover 112 drives the control switch 131 to be disconnected, so that the relay 132 is powered off, and the power supply circuit b is turned off. In this way, when the cover 112 is opened, the control switch 131 is connected, which can realize the conduction of the power supply circuit b, so that the water pump 120 can work normally. When the cover 112 is switched to the closed position, the control switch 131 is disconnected, so that the power supply circuit b is turned off, so that the water pump 120 can stop working, which is simple in structure and easy to operate.

[0064] It should be noted that in this embodiment, the relay 132 can be a normally open relay 132. The normally open relay 132, also known as the normally open contact relay 132, is an electrical control device used to control the on-off state of the circuit a. In the power-off state, the contacts are open; in the power-on state, the contacts are closed, thereby allowing current to pass through.

[0065] Referring to Figure 3 and Figure 4 , Figure 3 is a structural schematic diagram of the control switch 131 (in the open state) and the cover 112 provided in an exemplary embodiment of the present disclosure, Figure 4 is Figure 3 a structural schematic diagram of the control switch 131 (in the closed state) and the cover 112. In some embodiments, the control switch 131 includes a first fixed part 1311 and a first movable part 1312, the first fixed part 1311 is installed on the expansion water tank 110, and the first movable part 1312 is arranged on the cover 112 and moves relative to the first fixed part 1311 between a first open position and a first connected position. When the first movable part 1312 is in the first open position, the first movable part 1312 is spaced apart from the first fixed part 1311, so that the control circuit a is electrically disconnected. When the first movable part 1312 is in the first connected position, the first movable part 1312 abuts against the first fixed part 1311, so that the control circuit a is electrically connected. In this way, the position of the movable part is changed by moving the cover 112, and the user can easily control the on-off of the circuit a. This design simplifies the operation process. Since the opening or closing action of the cover 112 is associated with the movement of the movable part, the user can naturally control the on-off of the circuit a when performing routine maintenance or inspection, without the need for additional operation steps. The on-off of the circuit a is controlled by physical contact, which avoids the electromagnetic interference and safety hazards that may be caused by the use of electronic switches.

[0066] Referring to Figure 3 and Figure 4In some embodiments, the cover 112 comprises a cover body 1121 and a sealing portion 1122, the cover body 1121 covers the filling port, the cover body 1121 is adapted to be movably mounted on the box body 111 between an open position and a closed position, the cover body 1121 is provided for mounting of the first fixed portion 1311, the sealing portion 1122 is movably mounted in the cover body 1121 along the direction of the filling port, along the direction of the filling port, the first movable portion 1312 is arranged on the side of the sealing portion 1122 facing the cover body 1121, and the sealing portion 1122 is adapted to drive the first movable portion 1312 to switch between the first connection position and the first disconnection position. In this way, the cover body 1121 is mainly responsible for covering the filling port and providing the basis for movable mounting, and the first fixed portion 1311 is mounted thereon, while the sealing portion 1122 is responsible for ensuring the sealing of the filling port, and the first movable portion 1312 of the control switch 131 is integrated. This means that the control switch 131 is integrated into the cover 112, further simplifying the design of the box body 111. The first movable portion 1312 is arranged on the side of the sealing portion 1122 facing the cover body 1121, which means that when the sealing portion 1122 moves, the first movable portion 1312 will also move accordingly. This design allows the user to indirectly control the on-off of the control circuit a by operating the sealing portion 1122. Due to the integration of the first movable portion 1312 and the sealing portion 1122, the user does not need to directly operate the control circuit a or the switch, thereby simplifying the operation process and improving the convenience. Since the first fixed portion 1311 and the first movable portion 1312 of the control switch 131 are integrated into the cover 112, it provides a more convenient access path for the user. When maintenance or troubleshooting is needed, the user only needs to open the cover 112 to easily access these components, simplifying the maintenance operation.

[0067] Referring again to Figure 3 and Figure 4In some embodiments, the first fixed part 1311 and the first movable part 1312 are clamped between the cover body 1121 and the sealing part 1122, and the first fixed part 1311 is connected to the side of the cover body 1121 facing the filling port. In this way, the first fixed part 1311 and the first movable part 1312 are clamped between the cover body 1121 and the sealing part 1122, which makes the structure of the entire cover 112 more compact and effectively utilizes the limited space. The control switch 131 of the control circuit a is integrated in the cover 112, and the first fixed part 1311 is connected to the side of the cover body 1121 facing the filling port, which provides stable support and ensures that the first fixed part 1311 will not loosen or shift due to vibration or external force during long-term use, thereby ensuring the stability and reliability of the control circuit a. At the same time, since the first movable part 1312 is associated with the sealing part 1122, when the sealing part 1122 moves, the first movable part 1312 can respond accordingly to realize the switching of the cover 112 state and the corresponding switching of the on-off state of the control switch 131, which is simple to operate. Integrating the key components of the control circuit a in the cover 112 can prevent external personnel from directly contacting or misoperating the control circuit a, thereby reducing the risk of electrical failure and safety accidents.

[0068] With reference to Figure 3 and Figure 4In some embodiments, the cover 112 further comprises a first elastic member 1123, which is arranged between the cover body 1121 and the sealing part 1122 in the direction of the filling port, and can switch the first movable part 1312 from the first connected position to the first disconnected position. In this way, when an external force acts on the sealing part 1122, it can move the sealing part 1122 and its associated first movable part 1312. Once the external force disappears, the first elastic member 1123 will exert its elastic effect to restore the sealing part 1122 and the movable part to the initial state, i.e. the first movable part 1312 is switched from the first connected position back to the first disconnected position. This automatic reset function ensures that the control circuit a can be automatically disconnected when not needed, improving the safety and reliability of the system. The first elastic member 1123 not only acts on the switching of the first movable part 1312, but also can exert a certain pressure on the sealing part 1122, thereby enhancing its sealing effect. When the sealing part 1122 is in contact with the filling port of the tank body 111, the elastic force of the first elastic member 1123 can ensure that a tight seal is formed between the sealing part 1122 and the filling port, preventing external contamination and moisture from entering the tank body 111 while preventing the liquid inside the tank body 111 from leaking. Since the first elastic member 1123 provides an automatic reset function, the user does not need to manually switch the first movable part 1312 back to the disconnected position, which simplifies the operation process and improves the user experience. The user only needs to exert enough force to overcome the elastic force of the first elastic member 1123 to move the first movable part 1312 from the disconnected position to the connected position; once the force is released, the first elastic member 1123 will automatically reset the first movable part 1312. In some cases, the first elastic member 1123 can also act as a buffer and shock absorber. When the tank body 111 is subjected to external impact or vibration, the first elastic member 1123 can absorb part of the energy, reducing the risk of wear and damage to the sealing part 1122 and the first movable part 1312. This helps to prolong the service life of the cover 112 and the control circuit a.

[0069] With reference to Figure 3 When the cover 112 is unscrewed from the tank body 111, the cover 112 is in the open position, the sealing part 1122 will not be subjected to the extrusion of the tank body 111, the first elastic member 1123 will return to normal, so that the first fixed part 1311 and the first movable part 1312 are arranged in a spaced manner, so that the control circuit a is in an electrically disconnected state. With reference to Figure 4 When the cover 112 is screwed onto the tank body 111, the sealing part 1122 is subjected to extrusion force from the tank body 111, so that the first movable part 1312 and the first elastic member 1123 are subjected to extrusion, and the first elastic member 1123 is deformed under the action of the pressure, so that the first movable part 1312 and the first fixed part 1311 abut, so that the control circuit a is electrically conductive.

[0070] It should be noted that the type of the first elastic member 1123 can be selected as needed. For example, the first elastic member 1123 can include a spring, a rubber pad, a silica gel pad, or the like. Specifically, the present application does not limit this.

[0071] Referring to Figure 5 and Figure 6 , Figure 5 is a schematic view of the structure of the switch assembly (in an electrically conductive state) and the cover 112, Figure 6 is Figure 5 a schematic view of the structure of the control switch 131 (in an electrically disconnected state) and the cover 112. In some embodiments, the switch assembly includes a second fixed part 133 and a second movable part 134. The second fixed part 133 is mounted to the expansion water tank 110, and the second movable part 134 is provided on the cover 112 and is movable relative to the second fixed part 133. In this way, the switch assembly and the cover 112 are associated. When the switch assembly is in an electrically conductive state, the second movable part 134 abuts against the second fixed part 133, which generally means that the circuit is closed, and the current can flow smoothly, so that the water pump 120 can work normally, so that the water pump 120 can output the liquid in the tank 111. When the switch assembly is in an electrically disconnected state, the second movable part 134 is spaced apart from the second fixed part 133, which means that the circuit is disconnected, and the current cannot flow, so that the water pump 120 stops working. Since the second movable part 134 is mounted to the cover 112 and can move relative to the second fixed part 133, it means that the switching of the switch assembly can be achieved by driving the cover 112 to move (such as pressing, rotating, etc.). This design generally can provide a more intuitive and more reliable operation mode.

[0072] It should be noted that in the above embodiments, the materials of the first fixed part 1311, the first movable part 1312, the second fixed part 133, and the second movable part 134 can be selected as needed. For example, the materials can include iron, stainless steel, or copper, etc. Specifically, the present application does not limit this.

[0073] Referring to Figure 5 and Figure 6In some embodiments, the cover 112 comprises a cover body 1121 and a sealing part 1122, the cover body 1121 covers the filling port, and the cover body 1121 is adapted to be movably mounted on the box body 111 between an open position and a closed position, so that the cover body 1121 can be movably mounted between the open position and the closed position, which provides a convenient operation mode for the user, and the user can open or close the filling port of the box body 111 by simply moving the cover body 1121. The cover body 1121 is provided with the second fixed part 133, and the sealing part 1122 is movably mounted in the cover body 1121 along the direction of the filling port. Along the direction of the filling port, the side of the sealing part 1122 facing the cover body 1121 is provided with the second movable part 134, and the sealing part 1122 is adapted to drive the second movable part 134 to move so that the second movable part 134 is in abutment or spaced apart from the second fixed part 133. The sealing part 1122 is movably mounted in the cover body 1121 along the direction of the filling port, which allows the sealing part 1122 to move relatively in the cover body 1121 to adjust the sealing state between the sealing part 1122 and the filling port. The second fixed part 133 is mounted on the cover body 1121, and the second movable part 134 is arranged on the side of the sealing part 1122 facing the cover body 1121. This arrangement allows the second movable part 134 to be in abutment or spaced apart from the second fixed part 133 with the movement of the sealing part 1122, so as to realize the conduction or disconnection of the circuit. The sealing part 1122 not only plays a sealing role, but also drives the relative position change of the second movable part 134 and the second fixed part 133 through its movement, which reduces the additional driving mechanism and improves the overall compactness and operation efficiency. The sealing part 1122 is movably mounted along the direction of the filling port, which can adjust the sealing state between the sealing part 1122 and the filling port according to the change of operation demand. This ensures that the box body 111 has good sealing performance in the closed state to prevent external impurities from entering the inside of the box body 111 or the liquid in the box body 111 from leaking.

[0074] Referring to Figure 5 and Figure 6In some embodiments, the cover 1121 is provided with a through hole extending in the direction of the filler neck, and a second fixing portion 133 is mounted on the side of the cover 1121 away from the sealing portion 1122 in the direction of the filler neck, and a second movable portion 134 is arranged on the side of the cover 1121 away from the sealing portion 1122 in the direction of the filler neck. The sealing portion 1122 is provided with a protrusion 140 extending out of the through hole and connected with the second movable portion 134. In this way, the through hole is provided on the cover 1121, which provides an extension channel for the protrusion 140 of the sealing portion 1122, so that the sealing portion 1122 can move accurately in the direction of the filler neck. The second fixing portion 133 is mounted on the side of the cover 1121 away from the sealing portion 1122, and the second movable portion 134 is also arranged on the side of the cover 1121 away from the sealing portion 1122 and connected with the sealing portion 1122 through the protrusion 140. This arrangement avoids the switch assembly occupying the internal space of the cover 1121, so that the structure of the cover 112 is more compact. The protrusion 140 of the sealing portion 1122 extends out of the through hole and is connected with the second movable portion 134, which indirectly connects the sealing portion 1122 and the second movable portion 134. By driving the sealing portion 1122 to move, the second movable portion 134 and the second fixing portion 133 can be brought into abutment or spaced apart, which is simple in structure and easy to operate. At the same time, the connection between the protrusion 140 and the second movable portion 134 also avoids the use of a complex transmission mechanism, simplifying the operation process.

[0075] With reference to Figure 5 and Figure 6In some embodiments, the cover 112 further comprises a second elastic member 1124, which is arranged between the cover body 1121 and the sealing part 1122 in the direction of the filling port, and is used to move the second movable part 134 away from the second fixed part 133 to abut against the second fixed part 133. In this way, the second elastic member 1124 is ingeniously arranged between the cover body 1121 and the sealing part 1122, and such an arrangement enables it to effectively exert elastic force on the sealing part 1122, thereby driving the second movable part 134 to move relative to the second fixed part 133. The second elastic member 1124 arranged in the direction of the filling port has the elastic force direction consistent with the relative movement direction of the cover body 1121 and the sealing part 1122, which helps to ensure the smoothness and consistency of the movement process. When an external force acts on the sealing part 1122, it can move the sealing part 1122 and the associated second movable part 134. Once the external force disappears, the second elastic member 1124 will exert its elastic effect to restore the sealing part 1122 and the second movable part 134 to the state of abutting against the second fixed part 133, i.e., the conduction position of the circuit. This automatic reset function improves the reliability and safety of the liquid cooling assembly 100. Since the second elastic member 1124 provides the automatic reset function, the user does not need to manually separate or abut the second movable part 134 against the second fixed part 133. This simplifies the operation process and improves the user experience.

[0076] It should be noted that the type of the second elastic member 1124 can be selected as needed, for example, the second elastic member 1124 can include a spring, a rubber pad, or a silica gel pad, etc. Specifically, the present application does not limit this.

[0077] With reference to Figure 5 When the cover 112 is in the open position, the second elastic member 1124 between the sealing part 1122 and the cover body 1121 is initially subjected to a compression force, and the sealing part 1122 is subjected to a downward force under the action of the reverse force of the second elastic member 1124. The second movable part 134 is connected through the boss 140 and the sealing part 1122, and the second movable part 134 is also subjected to a downward force, so that the second movable part 134 abuts against the second fixed part 133, and the switch assembly is in an electrically conductive state. With reference to Figure 6 When the cover 112 is in the closed position, the sealing part 1122 is subjected to a compression force to compress the second elastic member 1124, the second movable part 134 is lifted by the boss 140, and the second movable part 134 is spaced apart from the second fixed part 133, so that the switch assembly is in an electrically disconnected state.

[0078] In addition, the connection manner of the second fixed part 133 and the cover body 1121 and the connection manner of the second movable part 134 and the sealing part 1122 can be selected as needed. For example, the second fixed part 133 can be connected and fixed with the cover body 1121 through at least one of glue, a screw joint, a buckle structure, and a magnetic attraction structure. The second movable part 134 can be connected and fixed with the sealing part 1122 through at least one of glue, a screw joint, a buckle structure, and a magnetic attraction structure, and the like. Specifically, the present application does not limit this.

[0079] With reference to Figure 1 and Figure 2 In some embodiments, the liquid cooling assembly 100 further comprises an insurance part 150, and the insurance part 150, the switch assembly, and the water pump 120 are arranged in series. In this way, the insurance part 150 serves as a safety device that can quickly cut off the power supply when the current is too large or the system is abnormal, thereby protecting other components from being damaged.

[0080] With reference to Figure 1 and Figure 2 In some embodiments, the liquid cooling assembly 100 further comprises a power supply 180, and the power supply 180, the insurance part 150, the switch assembly, and the water pump 120 are arranged in series. In this way, when the switch assembly is in an electrically conductive state, the power supply 180 can supply power to the water pump 120, so that the water pump 120 works to output the liquid in the tank 111.

[0081] With reference to Figure 1 and Figure 2 In some embodiments, the liquid cooling assembly 100 further comprises a liquid level display part 160, and the liquid level display part 160 is installed on the expansion water tank 110. The liquid level display part 160 is used to display the liquid level of the liquid in the expansion water tank 110. In this way, the liquid level display part 160 can display the liquid level of the liquid in the expansion water tank 110 in real time and intuitively, so that the operator can quickly understand the liquid storage condition in the system. By monitoring the liquid level, it can be ensured that the liquid cooling system will not dry out when running due to insufficient liquid, thereby protecting the system components from being damaged. The main function of the expansion water tank 110 is to absorb the pressure fluctuation in the system and store excess liquid. The liquid level display part 160 helps the operator to control the liquid level in the expansion water tank 110, thereby indirectly controlling the pressure of the system and ensuring that the system runs within a safe range.

[0082] It should be noted that the type of liquid level display part 160 can be selected as needed. For example, in an embodiment, the liquid level display part 160 can include a liquid level display glass column, both ends of which are connected to the tank 111, one end of which is arranged adjacent to the bottom of the tank 111, and the other end of which is arranged adjacent to the top of the tank 111. The liquid level display glass column is the configuration of the stainless steel expansion tank 110, and the plastic expansion tank 110 can directly see the liquid level, and the liquid level display glass column can not be used. Of course, in other embodiments, the liquid level display part 160 can also include a single light column liquid level display, a magnetic flap liquid level meter, a floating ball liquid level meter, a glass tube / glass plate liquid level meter, a pressure type liquid level transmitter, or a capacitive liquid level meter, etc. Specifically, the present application does not limit the type of liquid level display part 160.

[0083] Referring to Figure 1 The liquid cooling assembly 100 further includes a motor 190, an electric control 1110, and a radiator 1120, which are connected in series with the water pump 120 and the expansion tank 110. In this way, the motor 190 and the electric control 1110 and other components generate a large amount of heat when working, and the radiator 1120 can effectively dissipate these heat, ensuring stable operation of the system. The series connection of the water pump 120 ensures the circulation of the cooling liquid in the system, thereby improving the heat dissipation efficiency. The expansion tank 110 can accommodate the liquid expansion and contraction caused by temperature changes and balance the system pressure and supplement the cooling liquid, further enhancing the heat dissipation performance of the system. The electric control 1110 system can accurately control the motor 190 and the water pump 120 and other components, thereby realizing accurate adjustment of the working state of the liquid cooling system. This helps to improve the response speed and stability of the system.

[0084] In an embodiment, the cover 112 is provided with a valve body for pressure relief when the positive pressure is too large and the negative pressure is too large, so that the air pressure in the expansion tank 110 can be ensured within a certain range, avoiding the expansion tank 110 being crushed or burst.
