Detailed Description

The principles and features of this application are described below in conjunction with the following drawings, the examples of which are set forth to illustrate the application and are not intended to limit the scope of the application.

As shown in fig. 40, 41 and 42, the present embodiment provides a water bottle 58 for use in a thermal management system. The water jug 58 is provided with an inlet 585, an outlet 586 and an exhaust port 581, as shown in fig. 41 and 42. A baffle 582 for increasing the length of the flow path between the inlet 585 and the vent 581 is also provided in the kettle 58, as shown in fig. 42.

The water bottle 58 according to the embodiment of the present application is provided with an inlet 585 for allowing the cooling liquid to enter the water bottle 58, an outlet 586 for allowing the cooling liquid to flow out of the water bottle 58, and an exhaust port 581 for exhausting the gas in the cooling liquid. And, still be equipped with guide plate 582 in kettle 58, guide plate 582 can increase the exhaust flow, is favorable to the gas in the coolant liquid fully to appear to improve the exhaust effect. Thus, the kettle 58 is more fully exhausted under the same pressure, which is beneficial to reducing the pressure fluctuation of the cooling liquid flow path and reducing the risk of tube explosion, thereby improving the use safety of the heat management system.

In an exemplary embodiment, the kettle 58 is provided with a nipple 587, as shown in FIG. 42. A partition 588 is provided in the pipe connector 587. A partition 588 divides the fitting 587 into an inlet 585 and an outlet 586. The pipe connector 587 is located at the bottom of the kettle 58, and the air outlet 581 is located at the top of the kettle 58.

Like this, the entry 585 and the export 586 of kettle 58 are integrated in the coupling 587 of kettle 58, are equivalent to entry 585 and export 586 sharing a port, can enough simplify the installation of kettle 58, and the kettle 58 of being convenient for is installed, has also greatly reduced the noise of rivers, is favorable to improving user's use and experiences.

And, the pipe connector 587 is located at the bottom of the water bottle 58, so that the inlet 585 and the outlet 586 are also located at the bottom of the water bottle 58, which facilitates the automatic downward flow of the cooling liquid under the action of gravity. The vent 581 is located at the top of the kettle 58 to facilitate the upward venting of the gas.

Wherein the partition 588 may be V-shaped.

In an exemplary embodiment, the baffle 582 includes: a first sub-board 5821, a second sub-board 5822, and a third sub-board 5823, as shown in fig. 41 and 42.

Wherein one end of the first sub-board 5821 is connected to the partition 588. One end of the second sub-board 5822 is connected with the other end of the first sub-board 5821, and a first overflowing channel is formed between the other end of the second sub-board 5822 and the first side wall 5841 of the kettle 58. One end of the third sub-board 5823 is connected with a first side wall 5841 of the water bottle 58, a second overflowing channel is formed between the other end of the third sub-board 5823 and a second side wall 5842 of the water bottle 58, the third sub-board 5823 is located between the second sub-board 5822 and the top wall of the water bottle 58, and the second side wall 5842 is opposite to the first side wall 5841.

In the scheme, the guide plate 582 comprises a first sub-plate 5821, a second sub-plate 5822 and a third sub-plate 5823, after the cooling liquid enters the kettle 58 through the inlet 585, the cooling liquid flows upwards along the first sub-plate 5821, then reaches the first overflowing channel along the second sub-plate 5822, then turns to flow to the second overflowing channel along the third sub-plate 5823, and then turns to the second overflowing channel until reaching the exhaust port 581 to be discharged. Therefore, the cooling liquid undergoes multiple steering in the flowing process, the exhaust flow is greatly increased, and the exhaust effect is also obviously improved.

In an exemplary embodiment, the third sub-panel 5823 has a length greater than a length of the second sub-panel 5822, as shown in fig. 41 and 42.

When the length of the third sub-plate 5823 is greater than that of the second sub-plate 5822, the exhaust flow path may be further increased, thereby further improving the exhaust effect.

In one exemplary embodiment, at least a portion of the baffle 582 is provided as a perforated plate.

At least one part of the guide plate 582 is set to be a porous plate, so that the gas in the cooling liquid can be discharged upwards through the holes of the porous plate, and the exhaust effect is also improved.

Such as: in the case where the baffle 582 includes the first sub-panel 5821, the second sub-panel 5822, and the third sub-panel 5823, only the third sub-panel 5823 may be provided as a porous plate, or both the second sub-panel 5822 and the third sub-panel 5823 may be provided as a porous plate.

In an exemplary embodiment, as shown in FIG. 1, the kettle 58 is provided in an elongated configuration. As shown in fig. 42, the kettle 58 includes a first sidewall 5841 and a second sidewall 5842 disposed opposite to each other along a length direction thereof, and the vent 581 is located between the first sidewall 5841 and the second sidewall 5842.

In the lengthwise direction of the kettle 58, the distance between the exhaust port 581 and the first sidewall 5841 is smaller than the distance between the exhaust port 581 and the second sidewall 5842, and the distance between the inlet 585 and the first sidewall 5841 is larger than the distance between the inlet 585 and the second sidewall 5842.

The design of the kettle 58 as a long and narrow structure increases the length of the kettle 58. Thus, the vent 581 can be disposed adjacent the first sidewall 5841 of the kettle 58 and the inlet 585 of the kettle 58 can be disposed adjacent the second sidewall 5842 of the kettle 58. Thus, compared with the scheme that the kettle 58 is substantially square or triangular, the distance between the inlet 585 of the kettle 58 and the air outlet 581 can be increased, so that the air exhaust flow path is increased, and the air exhaust effect is further improved.

In an exemplary embodiment, the cross-sectional flow area of the inlet 585 is less than the cross-sectional flow area of the outlet 586, as shown in FIG. 42.

Thus, the flow of the cooling liquid entering the kettle 58 is relatively small, which is beneficial to reducing the flow resistance and reducing the noise.

In one example, a water level sensor 583 is also provided at the top of the kettle 58, as shown in FIG. 39, for sensing the water level within the kettle 58.

The embodiment of the present application further provides a thermal management system, which includes the kettle 58 of any of the above embodiments.

The thermal management system provided by the embodiment of the application comprises the kettle 58 of any one of the above embodiments, so that all the beneficial effects of any one of the above embodiments are achieved, and the details are not repeated herein.

In an exemplary embodiment, the thermal management system further comprises: the coolant circuit header 200.

The cooling liquid path integrated base 200 comprises a kettle connecting portion 415, a kettle inlet 4151 and a kettle outlet 4152 are arranged on the kettle connecting portion 415, the kettle inlet 4151 is in butt joint communication with an inlet of the kettle 58, the kettle outlet 4152 is in butt joint communication with an outlet of the kettle 58, and a pipe joint of the kettle 58 is connected with the kettle connecting portion 415 through welding.

The coolant flow field header 200 is used to integrally mount some components of the coolant flow system, and achieves modular integration, thereby facilitating miniaturization and compactness of the thermal management system. The kettle 58 is connected with the kettle connecting part 415 in a welding (such as ultrasonic welding, fusion welding and the like) mode, so that an O-shaped sealing ring between the kettle 58 and the kettle connecting part 415 can be omitted, and the kettle 58 can be effectively prevented from leaking cooling liquid.

In an exemplary embodiment, a water kettle 58 is provided at the top of the coolant circuit of the thermal management system to facilitate the venting of gases.

In an exemplary embodiment, the coolant circuit nest 200 includes: a five-way valve connection 44, a motor thermal management flow path connection 41, a battery thermal management flow path connection 42, and a radiator connection 43.

As shown in fig. 31 and 32, the five-way valve connecting portion 44 is provided with five transition grooves spaced from each other, which are provided in one-to-one correspondence communication with the five passages of the five-way valve 100. The five-way valve 100 is a three-position five-way valve having three modes of operation. The motor thermal management flow path connection part 41 is provided with a first inlet 411 and a first outlet 412. The battery thermal management flow path connection part 42 is provided with a second inlet 421 and a second outlet 422. The radiator connection portion 43 is provided with a third inlet 431 and a third outlet 432.

The first inlet 411, the first outlet 412, the second inlet 421, the second outlet 422, and the third outlet 432 are respectively in one-to-one correspondence with the five transition grooves, and the third inlet 431 is in communication with the first outlet 412.

The coolant circuit assembly 200 provided in the embodiment of the present application includes a five-way valve connection portion 44, a motor thermal management flow path connection portion 41, a battery thermal management flow path connection portion 42, and a heat sink connection portion 43. The five-way valve connection 44 may be connected with a three-position five-way valve having three modes of operation. The motor thermal management flow path connection part 41 may be connected to a component of the motor thermal management flow path, the battery thermal management flow path connection part 42 may be connected to a component of the battery thermal management flow path, and the heat sink connection part 43 may be connected to the heat sink 57.

Since the five transition grooves of the five-way valve connecting portion 44 may be in one-to-one correspondence with the five passages of the five-way valve 100, the first inlet 411 and the first outlet 412 may be in correspondence with two transition grooves, the second inlet 421 and the second outlet 422 may be in correspondence with the other two transition grooves, the third outlet 432 may be in correspondence with the remaining one transition groove, and the third inlet 431 may be in correspondence with the first outlet 412.

Therefore, the coolant circuit integrated base 200 of the present embodiment can implement integrated installation of the five-way valve 100, the motor thermal management flow path, the battery thermal management flow path, and the heat sink 57, thereby facilitating simplification of the structure of the thermal management system and reducing the production cost.

Compared with the mode that a plurality of control valves are arranged to switch the working modes of the cooling liquid flow path of the thermal management system, the scheme can enable the cooling liquid flow path of the thermal management system to be switched among three working modes by arranging the five-way valve 100, thereby being beneficial to simplifying the structure and the electric control mode of the thermal management system and further reducing the production cost.

Also, the five-way valve 100 is simpler in structure than a control valve using an integrated form, such as an eight-way valve. The cross-sectional area of the flow path of the five-way valve 100 can be made larger for a substantially equivalent volume, thereby reducing the operational flow resistance. In addition, in the five-way valve 100 of the present solution, three valve positions correspond to three working modes, and the problem of gear skipping does not exist.

In addition, the eight-way valve is not suitable for a direct system, and the five-way valve 100 and the cooling liquid path assembly base 200 of the present application may be applied to a direct system, which is beneficial to reducing the number of control valves of the direct system and further simplifying the structure of the thermal management system.

In one example, when the five-way valve 100 is in the first operation mode, the first inlet 411 and the second outlet 422 are communicated through the five-way valve 100, and the third outlet 432 and the second inlet 421 are communicated through the five-way valve 100, and since the first outlet 412 and the third inlet 431 are communicated, the motor thermal management flow path, the heat sink 57 and the battery thermal management flow path are communicated end to form a closed loop, as shown in fig. 25, in which the heat sink 57 can be used to dissipate heat of the battery and the motor at the same time.

When the five-way valve 100 is in the second operating mode, the first outlet 412 and the second inlet 421 are communicated through the five-way valve 100, the second outlet 422 and the first inlet 411 are communicated through the five-way valve 100, and the motor thermal management flow path and the battery thermal management flow path are communicated end to form a closed loop, as shown in fig. 27, in this mode, the battery can be heated by using the residual heat of the motor.

When the five-way valve 100 is in the third operation mode, the first inlet 411 and the third outlet 432 are communicated through the five-way valve 100, and the second inlet 421 and the second outlet 422 are communicated through the five-way valve 100, and since the first outlet 412 and the third inlet 431 are communicated, the motor thermal management flow path and the heat sink 57 are connected in series to form a closed loop, and the battery thermal management flow path alone forms a closed loop, as shown in fig. 29. In this mode it is possible to cool the motor with the radiator 57 and the battery with the extra-cabin evaporator 54(chiller), i.e.: the motor and the battery are cooled separately.

In an exemplary embodiment, as shown in fig. 30 and 31, five transition grooves are distributed in two rows and three rows, the first row is respectively a first transition groove 441, a second transition groove 442 and a third transition groove 443 which are adjacently arranged in sequence, the second row is respectively a fourth transition groove 444 and a fifth transition groove 445, the second transition groove 442 and the fourth transition groove 444 are located in the same row, and the third transition groove 443 and the fifth transition groove 445 are located in the same row.

The first inlet 411 is communicated with the fifth transition groove 445, the first outlet 412 is communicated with the first transition groove 441, the second inlet 421 is communicated with the second transition groove 442, the second outlet 422 is communicated with the third transition groove 443, the third outlet 432 is communicated with the fourth transition groove 444, and the third inlet 431 is also communicated with the first transition groove 441. Since the third inlet 431 is also communicated with the first transition groove 441, the third inlet 431 and the first outlet 412 may be communicated through the first transition groove 441.

In an exemplary embodiment, when the five-way valve 100 is in the first operating mode, the second transition groove 442 is in communication with the fourth transition groove 444, and the third transition groove 443 is in communication with the fifth transition groove 445, as shown in fig. 25.

In other words, in this mode, the fifth transition groove 445 and the third transition groove 443 may be communicated through the five-way valve 100, so that the first inlet 411 and the second outlet 422 may be communicated through the five-way valve 100; the second transition groove 442 and the fourth transition groove 444 may communicate through the five-way valve 100, so that the third outlet 432 and the second inlet 421 may communicate through the five-way valve 100. Therefore, the motor thermal management flow path, the radiator 57 and the battery thermal management flow path are communicated end to form a closed loop, and the radiator 57 can be used for radiating heat of the battery and the motor at the same time in the mode.

When the five-way valve 100 is in the second operation mode, the first transition groove 441 is in communication with the second transition groove 442, and the third transition groove 443 is in communication with the fifth transition groove 445, as shown in fig. 27.

In other words, in this mode, the first and second transition grooves 441 and 442 may communicate through the five-way valve 100, so that the first and second outlets 412 and 421 may communicate through the five-way valve 100; the third and fourth transition grooves 443, 444 may communicate through the five-way valve 100 such that the second outlet 422 and the first inlet 411 may communicate through the five-way valve 100. Therefore, the motor heat management flow path and the battery heat management flow path are communicated end to form a closed loop, and the battery can be heated by using the waste heat of the motor in the mode.

When the five-way valve 100 is in the third operation mode, the second transition groove 442 is in conduction with the third transition groove 443, and the fourth transition groove 444 is in conduction with the fifth transition groove 445, as shown in fig. 29.

In other words, in this mode, the fourth transition groove 444 and the fifth transition groove 445 may communicate through the five-way valve 100, so that the first inlet 411 and the third outlet 432 may communicate through the five-way valve 100; the second and third transition grooves 442 and 443 may communicate through the five-way valve 100 such that the second inlet 421 and the second outlet 422 may communicate through the five-way valve 100.

As shown in fig. 4, the housing 1 is provided with a valve chamber 1111 and five passages communicating with the valve chamber 1111. The valve element 2 (shown in fig. 6 and 7) is at least partially disposed in the valve chamber 1111 and configured to rotate relative to the housing 1 between a first position (shown in fig. 24), a second position (shown in fig. 26), and a third position (shown in fig. 12 to 21 and 28) for controlling the communication relationship among the five passages, so that the five-way valve 100 can be switched among the first operation mode, the second operation mode, and the third operation mode.

In an exemplary embodiment, as shown in fig. 2, 3 and 16, five passages are distributed in two rows in the axial direction of the spool 2 and in three rows in the circumferential direction of the spool 2. The valve body 2 is provided with two axial communication grooves (i.e., a first communication groove 281 and a second communication groove 282 described below as shown in fig. 17 and 20) which are provided in the axial direction of the valve body 2 for communicating two passages located in the same row, and two circumferential communication grooves (i.e., a third communication groove 283 and a fourth communication groove 284 described below as shown in fig. 7 and 14). The circumferential communicating groove is arranged along the circumferential direction of the valve core 2 and used for communicating two adjacent channels in the same row.

In an exemplary embodiment, as shown in fig. 2 and 3, three rows of passages are respectively a first row of passages, a second row of passages and a third row of passages adjacently disposed in the circumferential direction of the spool 2, and the first row of passages includes one passage.

The two circumferential communication grooves are adjacently arranged along the axial direction of the valve core 2 to form a first row of communication grooves, and the two axial communication grooves are adjacently arranged along the circumferential direction of the valve core 2 to form a second row of communication grooves and a third row of communication grooves.

The first row of communicating grooves and the second row of communicating grooves are arranged adjacently along the circumferential direction of the valve core 2, and the arrangement direction of the first row of communicating grooves, the second row of communicating grooves and the third row of communicating grooves is the same as the arrangement direction of the first row of channels, the second row of channels and the third row of channels.

In an exemplary embodiment, as shown in fig. 2 and 3, five channels are respectively identified as a first channel 1121, a second channel 1122, a third channel 1123, a fourth channel 1124, and a fifth channel 1125. The first passage 1121, the second passage 1122, and the third passage 1123 are arranged side by side in this order in the circumferential direction of the spool 2. The fourth passage 1124 and the fifth passage 1125 are arranged side by side in the circumferential direction of the spool 2, the fourth passage 1124 and the second passage 1122 are arranged side by side in the axial direction of the spool 2, and the fifth passage 1125 and the third passage 1123 are arranged side by side in the axial direction of the spool 2. The two axial communication grooves are respectively identified as a first communication groove 281 and a second communication groove 282, and the two circumferential communication grooves are respectively identified as a third communication groove 283 and a fourth communication groove 284.

As shown in fig. 24, when the spool 2 is in the first position, the first communication groove 281 communicates with the second passage 1122 and the fourth passage 1124, the second communication groove 282 communicates with the third passage 1123 and the fifth passage 1125, and the third communication groove 283 communicates with the first passage 1121. Since the third communicating groove 283 communicates only with the first passage 1121, it corresponds to closing the first passage 1121; the fourth communicating groove 284 is not communicated with the five passages. This mode is the first mode of operation of the five-way valve 100.

As shown in fig. 26, when the valve body 2 is at the second position, the third communication groove 283 communicates with the first passage 1121 and the second passage 1122, and the first communication groove 281 communicates with the third passage 1123 and the fifth passage 1125. While the second communicating groove 282 is not communicated with the five passages; the fourth communication groove 284 communicates only with the fourth passage 1124, which corresponds to closing the fourth passage 1124. This mode is the second mode of operation of the five-way valve 100.

As shown in fig. 27, when the valve body 2 is at the third position, the third communicating groove 283 communicates with the second passage 1122 and the third passage 1123, and the fourth communicating groove 284 communicates with the fourth passage 1124 and the fifth passage 1125. The first communicating groove 281 is not communicated with the five passages, and the second communicating groove 282 is also not communicated with the five passages. This mode is the third mode of operation of the five-way valve 100.

Thus, the five-way valve 100 has three different operation modes, and when the valve core 2 is rotated by one gear, one operation mode is switched, the coolant flow path of the thermal management system can also have three different operation modes, and the flow direction of the liquid in the three operation modes can be switched by controlling the five-way valve 100.
