[0065] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0066] Please refer to Figures 1 to 10 As shown, according to the first aspect of the present application, a water tank device 100 is provided, comprising: a water tank body 110 , an external flow channel device 120 , a working fluid pump 130 and an electric control valve 140 .

[0067] The water tank body 110 is formed with a receiving cavity for receiving a working medium. When the water tank body 110 is integrated into a vehicle, the water tank body 110 can be used as an auxiliary water tank of the vehicle and provide a working medium to the cooling circuit of the vehicle. The working medium can be, for example, a coolant such as water.

[0068] refer to Figure 2 、 Figure 3As shown, the external flow channel device 120 is formed with an external flow channel 121 arranged outside the accommodating chamber, and the working fluid pump 130 is respectively connected to the accommodating chamber and the external flow channel 121 to pump the working fluid in the accommodating chamber into the external flow channel device 120. The electric control valve 140 is respectively connected to at least two external flow channels 121 to connect or disconnect the two external flow channels 121. That is, the electric control valve 140 is used to control the connection and disconnection between the external flow channels 121, so that the external flow channel 121 is equivalent to being used as a pipeline for the circulation of the working fluid, but the external flow channel 121 is directly formed on the external flow channel device 120, so the internal structure of the water tank device 100 is relatively simple, and there is no need to set up complex pipelines. In this application, the water tank body 110, the working fluid pump 130 and the electric control valve 140 are all arranged on the same side of the external flow channel device 120.

[0069] With the above solution, an external flow channel device is installed outside the water tank body. The internal structure of the water tank device is relatively simple, eliminating the need for complex piping, and is easy to install and disassemble, thereby facilitating assembly and maintenance. At the same time, the water tank body, the working fluid pump, and the electronically controlled valve are arranged on the same side of the external flow channel device. In other words, the installation base of the water tank body, the working fluid pump, and the electronically controlled valve is on the same side of the external flow channel device. This not only facilitates the positioning and installation of the various components, but also further facilitates the installation and disassembly of the various components.

[0070] Furthermore, in actual use, corresponding external flow channels 121 can be flexibly configured according to the vehicle's usage requirements. Thus, under the on-off control of the electrically controlled valve 140, the working fluid is delivered to different working components through different external flow channels 121 to meet the vehicle's cooling needs. Replacing complex pipes with external flow channels 121 results in a relatively simple structure. Furthermore, since the external flow channels 121 are located outside the water tank body 110, they do not occupy the volume of the accommodating cavity, allowing the water tank body 110 to accommodate more working fluid, meeting usage requirements and adapting to operating conditions that require more working fluid.

[0071] In a specific solution, the working medium may be, for example, cooling water or other substances.

[0072] In some embodiments, reference Figure 1 and Figure 2 As shown, the electrically controlled valve 140 is arranged outside the accommodating cavity, which can facilitate the installation, disassembly and maintenance of the electrically controlled valve 140 .

[0073] In some embodiments, reference Figure 1As shown, the electrically controlled valve 140 and the working fluid pump 130 are located on the same side of the water tank body 110. Considering that the water tank body 110 needs to have sufficient space to allow the accommodating cavity to have a large volume so that the accommodating cavity can accommodate a sufficient amount of working fluid, the configuration of the electrically controlled valve 140 and the working fluid pump 130 being located on the same side of the water tank body 110 can fully utilize the side space of the water tank body 110, and is conducive to integrating the electrically controlled valve 140 and the working fluid pump 130 in a limited space while ensuring easy assembly and disassembly, and is convenient for configuring the corresponding external flow channel 121 between the electrically controlled valve 140, the working fluid pump 130 and the water tank body 110, that is, it is conducive to the spatial layout configuration of the external flow channel 121.

[0074] It is understood that the external flow channel device 120 can be flexibly configured with multiple different external flow channels 121 to connect the water tank device 100 and external components connected to the water tank device 100. The following will exemplify some external flow channels 121 configured on the external flow channel device 120.

[0075] In some embodiments, reference Figure 4 、 Figure 5 as well as Figure 9 As shown, the water tank body 110 is provided with a water tank outlet 110a that is in communication with the accommodating chamber. The external flow channel device 120 is provided with an external water inlet 120a and an external water outlet 120b. The external water inlet 120a is in communication with the water tank outlet 110a. The external water inlet 120a is in communication with the pump inlet 131 of the working fluid pump 130 at least through the external flow channel 121. The pump outlet 132 of the working fluid pump 130 is in communication with at least one valve inlet of the electric control valve 140 through at least the external flow channel 121. One valve outlet of the electric control valve 140 is in communication with at least the external water outlet 120b through the external flow channel 121.

[0076] In some embodiments, reference Figure 7 and Figure 10 As shown, the external flow channel 121 includes: a first flow channel 121a and a second flow channel 121b. Among them, the first flow channel 121a is used to communicate with the external water inlet 120a and the pump inlet 131 of the working fluid pump 130 respectively, and the external water inlet 120a is connected to the water tank outlet 110a, that is, the working fluid in the accommodating chamber flows from the first flow channel 121a to the pump inlet 131. The second flow channel 121b is used to communicate with the pump outlet 132 of the working fluid pump 130. A valve inlet of the electric control valve 140 is connected to the second flow channel 121b, so that the electric control valve 140 can realize the circulation of the working fluid between different external flow channels 121 by controlling the opening and closing of the valve inlet and a certain valve outlet.

[0077] In some embodiments, the external flow channel 121 includes: a third flow channel 121c. The third flow channel 121c is connected to the second flow channel 121b through the electric control valve 140, that is, one of the valve outlets of the electric control valve 140 is connected to the second flow channel 121b. The external water outlet 120b is connected to the third flow channel 121c, so that one valve outlet of the electric control valve 140 is connected to the external water outlet 120b through the third flow channel 121c. In this way, as needed, an external pipeline can be connected to the external water outlet 120b to guide the working medium to the working component to be cooled, and the connection between the second flow channel 121b and the third flow channel 121c is controlled by the electric control valve 140 to control whether the working component is cooled.

[0078] In some embodiments, reference Figure 7 and Figure 8 As shown, the external flow channel 121 also includes: a fourth flow channel 121d. Among them, the fourth flow channel 121d is provided with an intermediate flow channel port 121e and a heat exchange outlet 121f connected to the second flow channel 121b. The second flow channel 121b is provided with a heat exchange inlet 121g. The heat exchange inlet 121g is connected to the heat exchange outlet 121f. Considering that the working fluid may need to flow to an external heat exchanger for heat exchange and cooling, by setting the fourth flow channel 121d, the heat exchanger can be connected between the heat exchange inlet 121g and the heat exchange outlet 121f, so that the working fluid can be cooled by heat exchange through the heat exchanger at any time, or heated by heat exchange through the heat exchanger, without the need for a control valve to control the on and off of the flow of the working fluid to the heat exchanger, which can be more adapted to actual use needs.

[0079] In some embodiments, the external flow channel 121 further includes a fifth flow channel 121h. The fifth flow channel 121h is provided with a bypass outlet 121i and a bypass inlet 121j that communicate with each other. The bypass inlet 121j is connected to the intermediate flow channel opening 121e via an electrically controlled valve 140, allowing the electrically controlled valve 140 to control the flow between the fourth flow channel 121d and the fifth flow channel 121h.

[0080] By adopting the above scheme, the control valve can be further used to control the opening and closing of the fourth flow channel 121d and the fifth flow channel 121h, so that the working fluid after heat exchange can flow to the working component through an external pipeline at the bypass outlet 121i, that is, the temperature of the working fluid in the third flow channel 121c and the fifth flow channel 121h can be different, thereby adapting to the working fluid temperature requirements of different working components.

[0081] In some embodiments, reference Figure 6As shown, the electrically controlled valve 140 can be configured to have a first valve water inlet 141 communicating with the second flow channel 121b, a first valve water outlet 142 communicating with the third flow channel 121c, a second valve water inlet 143 communicating with the fourth flow channel 121d, and a second valve water outlet 144 communicating with the fifth flow channel 121h. The electrically controlled valve 140 can electrically control the connection and disconnection between the first valve water inlet 141 and the first valve water outlet 142, and can electrically control the connection and disconnection between the second valve water inlet 143 and the second valve water outlet 144.

[0082] It should be noted that more external flow channels 121 or more electrically controlled valves 140 can be further provided on the external flow channel device 120 to meet the use requirements of more working components. The inventive concept of this application is to use external flow channels 121 to replace complex pipeline designs. This application does not limit the number of external flow channels 121 or the type and number of electrically controlled valves 140 that control the opening and closing of each external flow channel 121.

[0083] In some embodiments, the water tank device 100 further includes a temperature sensor 150. The temperature sensor 150 is used to detect the temperature of the working fluid within the external flow channel 121. The external flow channel device 120 is provided with a sensor mounting hole 121k that communicates with the second flow channel 121b. The temperature sensor 150 is inserted into the second flow channel 121b through the sensor mounting hole 121k. This allows the temperature of the working fluid pumped by the working fluid pump 130 to be detected, facilitating subsequent temperature control of the working fluid by, for example, transferring the working fluid from the working fluid pump 130 to a heat exchanger for heat exchange.

[0084] In some embodiments, the temperature sensor 150 and the water tank body 110 are arranged on the same side of the external flow channel device 120, that is, the temperature sensor 150, the electric control valve 140, the working fluid pump 130 and the water tank body 110 are all arranged on the same side of the external flow channel device 120, which facilitates the positioning and installation between the temperature sensor 150 and other components, and also facilitates the installation and disassembly of the temperature sensor 150.

[0085] In some embodiments, the external flow channel device 120 is provided with a working fluid inlet 1211 that communicates with the first flow channel 121a. The working fluid inlet 1211 is connected to the pump inlet 131 of the working fluid pump 130 through the first flow channel 121a. The working fluid inlet 1211 can be connected to the vehicle's main water tank, for example, so that the working fluid pump 130 can pump the working fluid in the main water tank.

[0086] In some embodiments, the external flow channel device 120 includes: a flow channel bottom plate 122 and a flow channel cover plate 123. The flow channel bottom plate 122 is formed with a plurality of bottom plate rib structures 122a for forming the external flow channel 121. The flow channel cover plate 123 is formed with a plurality of upper plate rib structures 123a for forming the external flow channel 121. The end faces of the bottom plate rib structure 122a and the upper plate rib structure 123a abut against each other so that the side faces of the two constitute the inner wall of the external flow channel 121. In actual production, the bottom plate rib structure 122a and the upper plate rib structure 123a can be fixed by threaded connection, welding, etc., so that the external flow channel 121 is formed by the flow channel bottom plate 122 and the flow channel cover plate 123. In a specific solution, the flow channel bottom plate 122 and the flow channel cover plate 123 can be connected together by plastic vibration welding to form a seal. Due to the extrusion vibration, the excellent strength of the connection structure and the good sealing effect are guaranteed.

[0087] In some embodiments, reference Figure 7 A mounting portion 122 b is provided on the flow channel bottom plate 122 . The mounting portion 122 b is located on one side of the external flow channel 121 , and the water tank body 110 can be fixed on the mounting portion 122 b of the flow channel bottom plate 122 .

[0088] In some embodiments, the flow channel cover plate 123 is formed with a mounting groove for at least inserting the working fluid pump 130 or the electric control valve 140 , thereby fixing the working fluid pump 130 or the electric control valve 140 on the flow channel cover plate 123 .

[0089] In some embodiments, a through hole is provided at the bottom of the installation groove to allow the working fluid pump 130 or the electric control valve 140 to at least partially extend into the external flow channel 121 .

[0090] Specifically, refer to Figure 3 , Figure 6 as well as Figure 9 As shown, the flow channel cover plate 123 may be provided with a first mounting groove 123b for inserting the working fluid pump 130 and a second mounting groove 123c for installing the electrically controlled valve 140. The water inlet of the working fluid pump 130 is connected to the first flow channel 121a through a first through hole 123d at the bottom of the first mounting groove 123b, and each valve inlet and valve outlet of the electrically controlled valve 140 is connected to different external flow channels through corresponding holes 123e.

[0091] In some embodiments, the mounting portion 122b is located on the same side of the bottom plate rib structure 122a and the upper plate rib structure 123a, that is, the water tank body 110 is installed on the side of the working fluid pump 130 and the electric control valve 140 to fully utilize the space on the side of the water tank body 110 and reduce the space occupied by the water tank device 100.

[0092] In some embodiments, the control valve can be fixed to the flow channel cover plate 123 by means of threaded connection or the like, and the flow channel cover plate 123 is provided with at least two positioning portions 123f. Correspondingly, the control valve is provided with a mating portion 145 that cooperates with the positioning portions 123f. The positioning portions 123f and the mating portion 145 engage with each other to position the control valve on the flow channel cover plate 123. For example, the positioning portion 123f can be a protrusion, and the mating portion 145 can be a groove for the protrusion to be inserted into. Alternatively, the positioning portion 123f can be a groove, and the mating portion 145 can be a protrusion that is inserted into the groove, so as to facilitate positioning the control valve on the flow channel cover plate 123 before the control valve is fixedly installed.

[0093] Please refer to Figure 11 As shown, according to a second aspect of the present application, a vehicle cooling system is provided, comprising: a heat exchanger, and the aforementioned water tank device 100. The heat exchanger has a first heat exchange channel for admitting a working medium. The first heat exchange channel is connected to a pump outlet 132 of a working medium pump 130 via an external flow channel 121, so that the working medium pumped by the working medium pump 130 flows into the first heat exchange channel.

[0094] By providing a heat exchanger, the working fluid can be heated or cooled by exchanging heat with other media flowing through the heat exchanger. For example, a relatively low-temperature gas can be introduced into the heat exchanger to exchange heat with the working fluid in the first heat exchange channel, cooling the working fluid before it flows to other working components. For example, as shown in the figure, the cooled working fluid can further flow through a control valve to a working fluid channel provided in the vehicle's powertrain, thereby cooling the powertrain.

[0095] In some embodiments, the vehicle cooling system further includes a motor radiator. The motor radiator is used to dissipate heat from the vehicle's motor. The motor radiator includes a second heat exchange channel for the flow of a working fluid. This second heat exchange channel is connected to the pump outlet 132 of the working fluid pump 130 via an electrically controlled valve 140 and an external flow channel. This allows the working fluid to flow from the water tank assembly 100 into the second heat exchange channel, where it absorbs heat generated by the vehicle's motor during operation, dissipating heat from the motor.

[0096] In some embodiments, the working fluid after heat exchange with the vehicle motor can be mixed with the working fluid after heat exchange and cooling in the heat exchanger, and then flow to the working fluid channel at the powertrain to dissipate heat from the powertrain.

[0097] In some embodiments, the working fluid after heat exchange with the powertrain can further flow to the main water tank or the water tank body 110 so as to be pumped again by the working fluid pump 130 and then flow to the external flow channel 121 to achieve the circulation flow of the working fluid.

[0098] Please refer to Figure 12As shown, according to a third aspect of the present application, a vehicle is provided, comprising the aforementioned on-board cooling system.

[0099] The vehicle may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this disclosure does not make any specific limitations on this.

[0100] Of course, the vehicle may preferably have an electronically controlled braking system.

[0101] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0102] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0103] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.

[0104] The above are merely preferred embodiments of the present application and do not constitute any form of limitation to the present application. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
