To reduce the footprint of the coolant circulation loop of an electric vehicle and save costs, in the present disclosure, as shown in fig. 1-11, an integrated kettle assembly 100 is provided. The jug base 10 is provided with a reservoir 11 for storing a coolant. The integrated kettle assembly 100 comprises a kettle base 10, a manifold block 20 and a water pump 40, wherein the manifold block 20 is fixedly arranged on the kettle base 10, and a part of the manifold block 20 is constructed as a valve body 51 of the electronic water valve 50. The electronic water valve 50 is used to change the flow direction of the liquid. The valve body 51 is formed with a plurality of valve ports 55 and an internal flow passage for communicating the valve ports 55 with each other, and the water outlet port 12 communicating with the liquid storage cavity 11 of the water jug base body 10 is provided on the water jug base body 10. The coolant in the liquid storage cavity 11 is output through the water outlet interface 12. The valve body 51 is provided with a liquid supplementing interface 21 communicated with the internal flow passage, and the liquid supplementing interface 21 is connected and directly communicated with the water outlet interface 12 so as to convey the coolant in the liquid storage cavity 11 to the electronic water valve 50. As shown in fig. 8, the water inlet of the water pump 40 is connected to and in direct communication with a corresponding valve interface 55.
The "direct communication" between the fluid infusion port 21 and the water outlet port 12 means that the kettle body and the valve body 51 are directly communicated through a flow channel formed by connecting the fluid infusion port 21 and the water outlet port 12, and the coolant in the fluid storage cavity 11 of the kettle body can directly flow into the electronic water valve 50 through the flow channel without being affected.
Similarly, the "direct communication" between the water inlet of the water pump 40 and the valve interface 55 means that the water inlet of the water pump 40 and the valve interface 55 are directly communicated through a flow channel formed by connecting the water inlet and the valve interface 55, and the coolant in the valve body 51 can directly flow into the water inlet of the water pump 40 through the valve interface 55 without being affected.
Through the technical scheme, the electronic water valve 50 and the water pump 40 are integrated on the water kettle base body 10 through the integrated block 20, the conduction states of the cooling loops can be switched through the electronic water valve 50, the cooling loops are provided with circulating power through the water pump 40, the electronic water valve 50 and the water pump 40 are integrated on the integrated block 20, the integrated block 20 and the water kettle base body 10 are integrated into a whole, the number of parts and the installation of a support for fixing the electronic water valve 50 and the water pump 40 are reduced, the assembly is more convenient, the assembly cost is reduced, the weight of the whole automobile is reduced, the cost and the oil consumption are reduced, the arrangement space of the whole automobile is saved, and the platform design of the whole automobile is facilitated.
And the communication between the kettle base body 10 and the electronic water valve 50 and between the electronic water valve 50 and the water pump 40 is realized through direct communication, so that the pipeline connection is omitted, the pipeline connection is convenient to simplify, the flow path of the coolant is shortened, and the unnecessary heat transfer is reduced. As the liquid supplementing function can be realized only by communicating the liquid supplementing interface 21 with the water outlet interface 12, the integrated block 20 can be matched with the kettle base bodies 10 with different volume models, and further matched with different vehicle models to achieve high platformization.
While the integrated water bottle assembly 100 is described in the present disclosure as an example of the application to a thermal management circulation system of an electric vehicle, it is understood that the integrated water bottle assembly 100 of the present disclosure can also be applied to other situations requiring fluid replacement and changing of fluid flow, such as a hydraulic system, an air conditioning system, a water circulation system, and the like.
In order to ensure that the water bottle base body 10 is replenished only at a proper time, optionally, in an embodiment of the present disclosure, as shown in fig. 2 to 5 and 9, a check valve assembly 60 is disposed on a connection flow passage of the water replenishing port 21 and the water outlet port 12, and the check valve assembly 60 is configured to open when the pressure in the internal flow passage is less than the pressure in the liquid storage cavity 11.
When the integrated kettle assembly 100 is applied to a thermal management system, when coolant is absent in a cooling circulation loop and the pressure is too low, the pressure in the liquid storage cavity 11 communicated with the cooling circulation loop is lower than the pressure in the liquid storage cavity 11, and at this time, the check valve assembly 60 is opened, and the coolant is replenished into the internal flow channel of the valve body 51 through the connecting flow channel of the liquid replenishing connector 21 and the water outlet connector 12, so that the coolant is replenished into the cooling circulation loop. Therefore, the liquid can be replenished only when the coolant is absent in the cooling circulation loop by arranging the check valve assembly 60, and the coolant in the thermal management system can be ensured not to flow back into the kettle base body 10, thereby preventing the coolant in the thermal management system and the coolant in the kettle base body 10 from flowing or flowing due to different temperatures, and further ensuring that the circulation loop in the thermal management system is in a normal circulation state.
The specific structure of the check valve assembly 60 is not limited in this disclosure, as long as one-way conduction in the flow passage can be ensured, and for example, a check valve may be provided in the connection flow passage between the fluid infusion port 21 and the water outlet port 12. Alternatively, in one embodiment of the present disclosure, as shown in fig. 5 and 9, the one-way valve assembly 60 includes a pressure actuating member 61 and a limiting member 62. The water outlet port 12 and the fluid infusion port 21 are in plug fit, and a mounting cavity 63 is formed at the plug fit position. One end of the mounting cavity 63 is communicated with the liquid storage cavity 11 through the first through hole 631, and the other end of the mounting cavity 63 is communicated with the internal flow passage through the second through hole 632. The pressure actuator 61 is disposed in the installation chamber 63 to block the first through hole 631 or to be separated from the first through hole 631 by the pressure of the liquid. The pressure actuator 61 is movable within the mounting chamber 63 under the pressure of the liquid. The limiting member 62 is fixedly disposed in the second through hole 632 to prevent the pressure actuator 61 from separating from the mounting cavity 63 from the second through hole 632, as shown in fig. 6, the limiting member 62 further has a notch 621, and the mounting cavity 63 is always communicated with the internal flow passage through the notch 621. Alternatively, the pressure actuator 61 may be a sealing ball made of a rubber material.
When the pressure in the internal flow passage of the valve body 51 is greater than the pressure in the kettle base body 10 and fluid replacement is not needed, the pressure actuator 61 moves towards the first through hole 631 under the action of the liquid pressure of the coolant flowing out from the fluid replacement port 21 until the first through hole 631 is sealed, so that the coolant in the thermal management system can be ensured not to flow back into the kettle base body 10; when the pressure in the internal flow passage of the valve body 51 is lower than the pressure in the kettle base body 10 and fluid replacement is required, the pressure actuator 61 moves towards the second through hole 632 under the action of the fluid pressure of the coolant flowing out from the water outlet port 12 to open the first through hole 631, and the coolant in the kettle base body 10 flows out from the first through hole 631 to the mounting cavity 63 and flows into the internal flow passage of the valve body 51 through the notch 621 of the limiting member 62, so that fluid replacement is performed on the thermal management system.
The specific structure of the limiting member 62 is not limited in this disclosure as long as the pressure actuator 61 is prevented from being separated from the mounting chamber 63 from the second through hole 632 and the mounting chamber 63 is communicated with the internal flow passage, and for example, the limiting member 62 may be a grid plate having a plurality of water permeable holes. Alternatively, in one embodiment, as shown in FIG. 6, the retainer 62 is configured in a generally chevron configuration with three support posts with the above-described notches 621 therebetween, and the mounting cavity 63 may communicate with the internal flow passage of the valve body 51 through gaps between the support posts. It is understood that in other embodiments, the stopper 62 may have a cross-shaped or a m-shaped structure.
The specific shape and arrangement of the water outlet port 12 and the fluid infusion port 21 are not limited in this disclosure, as long as the water outlet port 12 and the fluid infusion port 21 can be directly communicated with each other, and optionally, in an embodiment of the present disclosure, as shown in fig. 2 to 3, 5 and 7, the water outlet port 12 is arranged to protrude from the bottom of the water bottle base body 10, and the fluid infusion port 21 is arranged to protrude from the top of the manifold block 20. The water outlet port 12 is matched with the liquid supplementing port 21 in an inserting manner, and a sealing element 71 is arranged at the matching position of the water outlet port 12 and the liquid supplementing port 21 so as to seal the matching position of the water outlet port 12 and the liquid supplementing port 21. The bottom of the kettle base body 10 is positioned on the side of the kettle base body 10 facing the manifold block 20, and the top of the manifold block 20 is positioned on the side of the manifold block 20 facing the kettle base body 10.
