Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a flow channel plate, a kettle integrated module and a vehicle. BACKGROUND

[0002] In order to improve the energy utilization efficiency of the whole vehicle, the energy management architecture of a new energy electric vehicle is complex, and each cooling liquid circuit needs to be coupled or decoupled under different working conditions. Taking the motor as an example, a large amount of heat will be generated when the motor is running, and overheating will cause demagnetization of the permanent magnet, decrease of efficiency, and even direct burning. The thermal management system actively dissipates heat from the motor through the cooling liquid cold circuit, and maintains it in a suitable working temperature range. On the other hand, the waste heat of the motor can be recycled and used to heat the battery pack or heat the passenger compartment in winter, thereby reducing the consumption of battery energy and indirectly improving the battery range. The motor cooling liquid circuit and the battery cooling liquid circuit are coupled and decoupled under different working conditions under the mediation of the integrated module and the water pump and valve.

[0003] In the related art, microchannels and one-way conduction structures are used to connect the motor, battery and heating circuits to each other in the flow channel plate of the integrated module, but the internal leakage of each circuit under the independent running mode cannot be detected. Therefore, how to detect the internal leakage of each circuit in the flow channel plate is a technical problem that needs to be solved at present. SUMMARY

[0004] The present application provides a flow channel plate, a kettle integrated module and a vehicle. The flow channel plate according to the embodiments of the present application can detect the internal leakage of each circuit under the independent running mode and avoid the quality risk caused by internal leakage.

[0005] In order to achieve the above purpose, the main technical scheme adopted by the present application includes: In a first aspect, the present application provides a flow channel plate, comprising a plate body, a first flow channel, an exhaust water replenishment channel and a plurality of second flow channels; the first flow channel and the plurality of second flow channels are arranged on the plate body, and the first flow channel and the plurality of second flow channels correspond to different circuits respectively; the exhaust water replenishment channel is arranged on the plate body and communicates with the first flow channel; wherein the flow channel plate further comprises a plurality of microchannels, the plurality of microchannels and the plurality of second flow channels correspond one by one, one side of each microchannel communicates with the corresponding second flow channel, and the other side communicates with the exhaust water replenishment channel.

[0006] According to the flow channel plate of the first aspect of the present application, the plurality of microchannels corresponding to the second flow channels respectively, and the second flow channels are communicated with the exhaust water supplement channel, on the one hand, the pressure of each second flow channel in the loop can be consistent with the pressure of the exhaust water supplement channel, thereby greatly reducing the risk of overpressure of the second flow channel loop, on the other hand, each microchannel is only communicated with the corresponding second flow channel and the exhaust water supplement channel, thereby further reducing the possibility of mutual interference of fluid media in different loops, and the microchannels are independent of each other in the flow channel plate body and are sealed at the installation surface end face of the kettle, so that the motor cooling loop, the battery cooling loop and the heating loop can be independently operated in three modes, thereby facilitating the detection of internal leakage, effectively avoiding the quality risk caused by internal leakage, reducing the safety hazard, and enhancing the product use convenience and reliability.

[0007] Optionally, the plate body has a first pipe wall and a first end wall, the first end wall has a first end face facing the expansion kettle, the first pipe wall surrounds the exhaust water supplement channel, the first end wall is provided with a water supplement opening and an exhaust opening, one side of the exhaust water supplement channel penetrates through the first end face, and the other side of each microchannel penetrates through the first end face.

[0008] In the above scheme, the other side of the microchannel and one side of the exhaust water supplement channel both penetrate through the first end face, which helps to ensure the structural strength and sealing performance of the microchannel and the exhaust water supplement channel, reduces the dead angle and leakage point of the flow channel, reduces the risk of medium leakage, ensures the stable channel shape and prevents deformation caused by external force, guarantees the continuous and reliable exhaust and water supplement functions, and ensures the operation state of each second flow channel and the corresponding microchannel is not affected by other microchannels or other second flow channels. When checking whether a loop is internally leaked, the opening on the first end face can be blocked by a tool or other tool to detect the internal leakage of the corresponding loop, and the influence of other second flow channels and corresponding microchannels on the detection can be avoided, thereby helping to accurately identify the loop where the internal leakage occurs.

[0009] Optionally, the exhaust water supplement channel includes a first exhaust water supplement channel, a second exhaust water supplement channel and a third exhaust water supplement channel, one side of the first exhaust water supplement channel, one side of the second exhaust water supplement channel and one side of the third exhaust water supplement channel all penetrate through the first end face.

[0010] In the above scheme, the exhaust water supplement channel is multiple, and the multiple exhaust water supplement channels can respectively supplement water for exhaust for the corresponding loops, and one side of the multiple exhaust water supplement channels penetrates through the first end face, thereby facilitating the detection of internal leakage of the corresponding loop by blocking the opening on the first end face by a tool or other tool, and helping to accurately identify the loop where the internal leakage occurs.

[0011] Optionally, the plurality of microchannels includes a first microchannel and a second microchannel, the first microchannel includes a first microhole penetrating through the first end face, and the second microchannel includes a second microhole penetrating through the first end face.

[0012] In the above scheme, the outlets of the first microchannel, the second microchannel, the first exhaust water supplement channel, the second exhaust water supplement channel and the third exhaust water supplement channel are separated from each other at the kettle mounting surface. When internal leakage detection is required, the corresponding outlet on the first end surface can be blocked, thereby facilitating internal leakage detection of the microchannel and the corresponding second flow passage, and ultimately realizing internal leakage detection in the independent operation mode of each circuit.

[0013] Alternatively, the other side of the second exhaust water supplement channel is in communication with the first flow passage, and the other side of the third exhaust water supplement channel is in communication with the heat exchanger.

[0014] In the above scheme, the second exhaust water supplement channel and the third exhaust water supplement channel are respectively in communication with the first flow passage and the heat exchanger, which can synchronously or independently exhaust the accumulated gas of the corresponding circuit, helps to exhaust the stagnant gas in the first flow passage and the gas generated during the operation of the heat exchanger, avoids the problem of incomplete exhaust or gas blockage caused by a single exhaust port, ensures smooth fluid flow, and improves the heat exchange or operation efficiency of the system.

[0015] Alternatively, the microchannel includes a first section and a second section. One end of the first section is in communication with the corresponding second flow passage. Along the length direction of the second section, the second section has a first end and a second end. The first end is connected to the other end of the first section, and the second end is connected to the exhaust water supplement channel. From the first end to the second end, the inner diameter of the second section gradually decreases.

[0016] In the above scheme, the tapered structure can reduce the probability of liquid flowing through the exhaust water supplement channel entering from the second end, reduce the liquid entering the first microchannel from the second end, ensure that the liquid inside the exhaust water supplement channel can supplement water or exhaust according to the predetermined route, ensure the efficiency of water supplementing or exhausting, and at the same time, the inner diameter of the second section gradually decreases, which can reduce the risk of leakage at the connection between the second end and the exhaust water supplement channel, and at the same time, the occupied space of the second end is reduced, so that the overall structure is more compact and interference with other flow passages is avoided.

[0017] Alternatively, the inner diameter of each microchannel is d, which satisfies: 1mm≤d≤3mm.

[0018] In the above scheme, since the inner diameter of the microchannel satisfies the above range, on the one hand, it can avoid excessive gas-liquid flow resistance caused by too narrow channel, ensure that the gas quickly converges and is exhausted under the assistance of the tapered structure, and the liquid flows smoothly, meet the flow demand of supplementing and exhausting, on the other hand, it can reduce the occupied space, make the overall structure more compact, avoid interference with other flow passages, reduce the probability of liquid flowing through the exhaust water supplement channel entering from the second end, reduce the liquid entering the first microchannel from the second end, ensure that the liquid inside the exhaust water supplement channel can supplement water or exhaust according to the predetermined route, and ensure the efficiency of water supplementing or exhausting.

[0019] Optionally, the first flow channel is used to supply liquid for the electric drive circuit.

[0020] In the above scheme, the electric drive circuit needs a more efficient liquid supply cycle due to the large amount of heat generated. Supplying liquid to the electric drive circuit through the first flow channel helps to ensure reliable electric drive heat dissipation, while avoiding interference between different circuits due to differences in liquid supply requirements, reducing the risk of mutual interference of fluid media of different temperatures in each circuit, making the gas-liquid separation of each circuit more complete, and helping to improve the exhaust effect.

[0021] In a second aspect, the embodiments of the present application provide a kettle integrated module, comprising: The flow channel plate according to any one of the embodiments; The expansion kettle is arranged on the flow channel plate, and the expansion kettle is in communication with the exhaust water supply channel.

[0034] With the rapid development of new energy electric vehicles, the diversity of sales areas and the fierce competition market, the demand for thermal management system of the whole vehicle is increasing, and the research of electric vehicle thermal management system is more and more valued.

[0035] In order to improve the energy utilization efficiency of the whole vehicle, the energy management architecture of new energy electric vehicles is complex, and each cooling liquid circuit needs to be coupled or decoupled under different working conditions. For example, the motor generates a large amount of heat during operation, and overheating can cause demagnetization of the permanent magnet, efficiency decline, or even direct burning. The thermal management system actively cools the motor through the cooling liquid cold circuit to maintain it in the appropriate working temperature range. On the other hand, the waste heat of the motor can be recycled and used to heat the battery pack or the passenger cabin in winter, thereby reducing the consumption of battery energy and indirectly improving the battery range. The motor cooling liquid circuit and the battery cooling liquid circuit are coupled and decoupled under different working conditions through the integration of modules, water pumps and valves.

[0036] In related technologies, the thermal management integrated module cooperates with the multi-way water valve and the water pump through the cooling liquid flow channel plate to couple and decouple the battery circuit, the motor circuit and multiple modes, realizing the function of multiple working modes.

[0037] The kettle is installed at a high position of the water side flow channel plate, and different circuits release gas into the kettle through the degassing channel, and different cavity regions are set in the kettle. The water side flow channel plate of the new energy vehicle thermal management integrated module often uses micropores or microchannels to solve the problem of liquid leakage between different circuits, and the problem of liquid level difference or gas backflow into the circuit in the two kettle cavities.

[0038] Among them, typical working condition one is two or multiple circuits in series, and the pressure difference between circuits caused by pre-pump water needs to be solved, which further leads to the influence of circuit self-liquid supplement port on main circuit flow; typical working condition two is two or multiple circuits isolation, and closed circuit needs to handle cooling liquid high temperature expansion overflow. Therefore, microchannels and one-way conduction structures are used in the flow channel plate of the integrated module to connect the motor, battery and heating circuits.

[0039] However, after using microchannels, it is not possible to detect the internal leakage of each circuit under independent operation mode, and it is not possible to identify and avoid the related risks of internal leakage of each flow channel of the product.

[0040] In view of this, in order to facilitate the detection of internal leakage of each flow channel in the flow channel plate 100, the embodiment of the present application proposes a flow channel plate 100, which is provided with a plurality of microchannels 150, and the plurality of microchannels 150 and the plurality of second flow channels 130 one-to-one correspond, one side of each microchannel 150 is in communication with the corresponding second flow channel 130, and the other side is in communication with the exhaust water replenishment channel 140; a plurality of microchannels 150 corresponding to the second flow channel 130, which connects each second flow channel 130 and the exhaust water replenishment channel 140, on the one hand, the pressure of the loop in which each second flow channel 130 is located is consistent with the pressure of the exhaust water replenishment channel 140, greatly reducing the risk of overpressure of the second flow channel 130 loop, on the other hand, each microchannel 150 is only in communication with the corresponding second flow channel 130 and the exhaust water replenishment channel 140, further reducing the possibility of mutual interference of fluid media in different loops, because the microchannel 150 and the second flow channel 130 are independent of each other, it is convenient to carry out internal leakage detection, can quickly locate the leakage point when the flow channel plate 100 occurs internal leakage, effectively avoids the quality risk caused by internal leakage, reduces the safety hidden danger, and at the same time enhances the product use convenience and reliability.

[0041] The flow channel plate 100, the kettle integrated module 1000 and the vehicle proposed by the embodiment of the present application are described below in conjunction with the drawings.

[0042] Please refer to Figure 1 and Figure 2 According to the flow channel plate 100 proposed by the first aspect of the present application, it comprises a plate body 110, a first flow channel 120, an exhaust water replenishment channel 140 and a plurality of second flow channels 130.

[0043] The first flow channel 120 and the plurality of second flow channels 130 are arranged on the plate body 110, and the first flow channel 120 and the plurality of second flow channels 130 correspond to different loops respectively; it can be understood that the first flow channel 120 and the plurality of second flow channels 130 are independent of each other, and are sealed at the kettle mounting surface end face, so as to realize the independent operation of the motor cooling loop, the battery cooling loop and the heating loop, detect internal leakage, effectively avoid the quality risk caused by internal leakage, reduce the safety hidden danger, and at the same time enhance the product use convenience and reliability, and are respectively located in different loops, which can respectively play the role of replenishing liquid for the corresponding loop. Specifically, the plate body comprises two cooperating front plate and rear plate, and the front plate and rear plate jointly enclose a plurality of flow channels in the inside.

[0044] Therefore, the liquid supplementing medium of different circuits can be prevented from flowing and mixing, the medium in each circuit is prevented from being affected by the medium in other circuits, the problem of insufficient or excessive liquid supplementing of part of the circuits caused by unified liquid supplementing is avoided, different circuits can maintain their respective thermal management states, the medium in the circuit needing cooling and the medium in the circuit needing uniform temperature are prevented from affecting each other, or the medium in the circuit needing cooling and the medium in the circuit needing heating are prevented from affecting each other, or the medium in the circuit needing heating and the medium in the circuit needing uniform temperature are prevented from affecting each other, and the operation accuracy and stability of the entire system are improved.

[0045] The exhaust water supplementing channel 140 is arranged on the plate body 110 and communicates with the first flow channel 120. It can be understood that bubbles are easily generated in the fluid circuit during operation due to the release of dissolved gas and the introduction of air during liquid supplementing. The retention of the bubbles can cause problems such as flow channel liquid supplementing flow fluctuation and flow channel internal pressure rise. The exhaust water supplementing channel 140 can play a role in exhausting the bubbles, ensuring the fluid filling degree in the flow channel and maintaining the stability of the liquid supplementing pressure and flow. When more gas is generated in the fluid medium in the first flow channel 120 and the liquid is insufficient, the fluid can be supplemented through the exhaust water supplementing channel 140, thereby ensuring the normal work of the circuit corresponding to the first flow channel 120.

[0046] The flow channel plate 100 is further provided with a plurality of microchannels 150. The plurality of microchannels 150 and the plurality of second flow channels 130 correspond to each other. One side of each microchannel 150 communicates with the corresponding second flow channel 130, and the other side communicates with the exhaust water supplementing channel 140.

[0047] It can be understood that each second flow channel 130 can communicate with the exhaust water supplementing channel 140 through the corresponding microchannel 150. Part of the fluid medium in the second flow channel 130 and the fluid medium in the exhaust water supplementing channel 140 are in contact, so that the pressure in the second flow channel 130 is the same as the pressure in the exhaust water supplementing channel 140. Therefore, the pressure in the circuit in which the second flow channel 130 is located can be ensured to be the same as the pressure in the exhaust water supplementing channel 140, and the risk of overpressure of the fluid medium in the circuit in which the second flow channel 130 is located is reduced.

[0048] At the same time, each microchannel 150 is independent of each other, and each second flow channel 130 is also independent of each other, that is, each second flow channel 130 only communicates with the corresponding microchannel 150, and each second flow channel 130 is independent of other second flow channels 130 and other microchannels 150. Therefore, the inner leakage detection of each second flow channel 130 and the corresponding microchannel 150 is facilitated, so that when the inner leakage of the flow channel plate 100 occurs, it can be quickly identified which second flow channel 130 or microchannel 150 has the inner leakage, the inner leakage detection in the independent operation mode of each circuit is realized, and the quality risk caused by the inner leakage is avoided.

[0049] Specifically, in the independent operation mode of each circuit, the first flow channel 120 and the plurality of second flow channels 130 are independently operated respectively, and when internal leakage occurs between the first flow channel 120 and any second flow channel 130, or when internal leakage occurs in the first flow channel 120, or when internal leakage occurs in a certain second flow channel 130 of the plurality of second flow channels 130, or when internal leakage occurs in several second flow channels 130 of the plurality of second flow channels 130, the internal leakage detection tool can be used for detection, so as to identify the position of the internal leakage and determine which flow channel has internal leakage, which helps to avoid the risk caused by internal leakage and improve the use convenience and reliability of the product.

[0050] As an example, the flow channel plate 100 can be part of a vehicle thermal management module, and the first flow channel 120 and the plurality of second flow channels 130 can be located in different circuits in the thermal management module, so as to ensure the stable operation of the thermal management module, and when the thermal management fails, the position of the internal leakage can be quickly determined, which helps to avoid the risk caused by internal leakage.

[0051] In other embodiments, please refer to Figure 1 and Figure 2 The plate body 110 has a first pipe wall 111 and a first end wall 112, the first end wall 112 has a first end face 112c facing the expansion kettle, and the first pipe wall 111 surrounds the exhaust water replenishment channel 140, one side of the exhaust water replenishment channel 140 penetrates the first end face 112c, and in specific embodiments, the first end wall 112 is provided with a water replenishment opening 112a and an exhaust opening 112b, the exhaust opening 112b and the water replenishment opening 112a are respectively communicated with the exhaust water replenishment channel 140, and the other side of each micro channel 150 penetrates the first end face 112c.

[0052] Specifically, the first pipe wall 111 is connected with the first end wall 112, and the side wall of each micro channel 150 is also connected with the first end wall 112, and the first pipe wall 111 and the side wall of the micro channel 150 are independent of each other, so as to ensure that the micro channel 150 and the exhaust water replenishment channel 140 are independent of each other, that is, the micro channel 150 is communicated with the exhaust water replenishment channel 140 through the exhaust opening 112b and the water replenishment opening 112a instead of directly penetrating the side wall of the exhaust water replenishment channel 140 and being communicated with the exhaust water replenishment channel 140, so that the structural strength and sealing performance of the micro channel 150 and the exhaust water replenishment channel 140 are ensured, the flow channel dead angle and leakage point are reduced, the medium leakage risk is reduced, the channel shape is stable and is not easy to be extruded and deformed by external force, and the continuous and reliable exhaust and water replenishment functions are ensured.

[0053] It can be understood that, since the opening of the micro-channel 150 is located at the first end face 112c, it is convenient to block the opening of the micro-channel 150 by a tool or other tool when detecting internal leakage, so as to ensure the sealing of the corresponding circuit during internal leakage detection, and ensure the accuracy of the detection result.

[0054] In the above scheme, the first pipe wall 111 and the side wall of the micro-channel 150 are independent of each other, which can reduce the gap at the joint of the side wall due to processing error or long-term pressure impact, so as to reduce the internal leakage between the micro-channel 150 and the exhaust water supplement channel 140, and reduce the probability of too much fluid medium entering the micro-channel 150 to affect the independent operation of each circuit. The independent side wall design makes the first pipe wall 111 and the micro-channel 150 only communicate through the exhaust port 112b and the water supplement port 112a of the first end wall 112, greatly reduces the leakage path, ensures that the medium in the micro-channel 150 and the medium in the exhaust water supplement channel 140 only interact at the preset position, and improves the overall sealing reliability.

[0055] Therefore, the running state of each second flow channel 130 and the corresponding micro-channel 150 is not affected by other micro-channels 150 or other second flow channels 130.

[0056] In addition, there is no need to open a hole position on the first pipe wall 111 for the micro-channel 150 to pass through, so that the structural integrity of the first pipe wall 111 can be completely preserved, and the problem of local strength weakening caused by pipe wall opening can be avoided. Especially when the exhaust water supplement channel 140 bears high pressure (such as system liquid supplement or exhaust process), the complete first pipe wall 111 can bear pressure more stably and is not easy to deform or break, which helps to prolong the service life of the flow channel plate 100.

[0057] Specifically, the opening of the micro-channel 150 corresponding to each second flow channel 130 is arranged on the first end wall 112, and the first end wall 112 is further provided with the exhaust port 112b and the water supplement port 112a. At the same time, the outlet of each micro-channel 150 is separated from the exhaust port 112b and the water supplement port 112a, respectively, which improves the isolation degree of the channel walls of the micro-channel 150 and the exhaust water supplement channel 140. When internal leakage detection is needed, the corresponding outlet on the first end wall 112 can be blocked, so as to facilitate the internal leakage detection of the second flow channel 130 corresponding to the micro-channel 150, and finally realize the internal leakage detection in the independent operation mode of each circuit.

[0058] When checking whether a certain circuit is internally leaked, the influence of other second flow channels 130 and corresponding micro-channels 150 on the detection can be avoided, so as to help accurately identify the circuit where the internal leakage is located.

[0059] In some specific embodiments, please refer to Figure 1 and Figure 2The exhaust port 112b includes a first exhaust port 112ba and a second exhaust port 112bb, and the first exhaust port 112ba and the second exhaust port 112bb are respectively located on both sides of the water supplement port 112a along the first direction X. Specifically, the first exhaust port 112ba and the second exhaust port 112bb are respectively arranged on both sides of the water supplement port 112a along the first direction X, the first direction X is parallel to the plane where the first end wall 112 is located, and the first exhaust port 112ba and the second exhaust port 112bb can respectively play a role of exhausting water. The mixture of liquid and gas can flow out of the flow channel plate 100 through the first exhaust port 112ba, and the mixture of liquid and gas can also flow out of the flow channel plate 100 through the second exhaust port 112bb.

[0060] In other embodiments, the exhaust water supplement channel 140 includes a first exhaust water supplement channel 141, a second exhaust water supplement channel 142, and a third exhaust channel 143, one side of the first exhaust water supplement channel 141, one side of the second exhaust water supplement channel 142, and one side of the third exhaust water supplement channel 143 all penetrate the first end surface 112c. Specifically, the first exhaust water supplement channel 141 is in communication with the water supplement port 112a, two ends of the first exhaust channel 142 are respectively in communication with the first exhaust port 112ba and the first flow channel 120, and two ends of the second exhaust channel 143 are respectively in communication with the second exhaust port 112bb and the heat exchanger.

[0061] Specifically, the two sides of the first exhaust water supplement channel 141 are respectively provided with the second exhaust water supplement channel 142 and the third exhaust channel 143, and the first exhaust water supplement channel 141 and the second exhaust water supplement channel 142 are at least partially spaced apart, the first exhaust water supplement channel 141 and the third exhaust water supplement channel 143 are also at least partially spaced apart, and the third exhaust water supplement channel 143 communicates the second exhaust port 112bb with the heat exchanger, so that the mixture of liquid and gas can be discharged out of the flow channel plate 100 after heat exchange through the heat exchanger, which can realize heat exchange and gas discharge.

[0062] In the above scheme, the second exhaust water supplement channel 142 and the third exhaust water supplement channel 143 respectively communicate the first flow channel 120 with the heat exchanger, which can synchronously or independently discharge the gas accumulated in the corresponding loop, which helps to discharge the stagnant gas in the first flow channel 120 and the gas generated during the operation of the heat exchanger, avoids the problem of incomplete exhaust or gas blockage caused by a single exhaust port 112b, ensures smooth fluid flow, and improves the heat exchange or operation efficiency of the system.

[0063] In other embodiments, please refer to Figure 1 and Figure 2The plurality of micro-channels 150 include a first micro-channel 151 and a second micro-channel 152, the first micro-channel 151 includes a first micro-hole 151a penetrating the first end face 112c, and the second micro-channel 152 includes a second micro-hole 152a penetrating the first end face 112c. Specifically, the first micro-channel 151 is in communication with the outside through the first micro-hole 151a, and the second micro-channel 152 is in communication with the outside through the second micro-hole 152a. The first micro-hole 151a and the second micro-hole 152a are both arranged on the first end wall 112, and the first micro-hole 151a and the second micro-hole 152a are spaced apart from each other, that is, the opening of the first micro-channel 151 and the opening of the second micro-channel 152 are spaced apart from each other, and the first micro-channel 151 and the second micro-channel 152 are two channels completely isolated from each other.

[0064] In the second direction Y, the first micro-hole 151a is opposite to the first exhaust port 112ba, and the second micro-hole 152a is opposite to the water supplement port 112a. The second direction Y intersects the first direction X. Specifically, the arrangement direction of the first micro-hole 151a and the second micro-hole 152a is the first direction X. On the one hand, the first micro-hole 151a is spaced apart from the second micro-hole 152a along the first direction X, and on the other hand, the first micro-hole 151a is opposite to the first exhaust port 112ba along the second direction Y, so that the first micro-hole 151a, the second micro-hole 152a, the first exhaust port 112ba and the second exhaust port 112bb are all spaced apart from each other.

[0065] That is, the outlets of the first micro-channel 151, the second micro-channel 152, the second exhaust water supplement channel 142 and the third exhaust water supplement channel 143 are separated from each other at the kettle mounting surface. When internal leakage detection is required, the first micro-hole 151a or the second micro-hole 152a on the first end wall 112 can be blocked, so as to facilitate the internal leakage detection of the micro-channel 150 and the corresponding second flow channel 130, and finally realize the internal leakage detection in the independent operation mode of each circuit.

[0066] At the same time, the first micro-hole 151a is indirectly communicated with the first exhaust port 112ba, and the second micro-hole 152a is indirectly communicated with the water supplement port 112a. The first micro-channel 151 can communicate the corresponding second flow channel 130 with the second exhaust water supplement channel 142, and the second micro-channel 152 can communicate the corresponding second flow channel 130 with the first exhaust water supplement channel 141, so as to ensure that the pressures of the two second channels and the exhaust water supplement channel 140 are the same.

[0067] In specific embodiments, the first micro-hole 151a and the second micro-hole 152a can also be spaced apart along the second direction Y, and both are opposite to the first exhaust port 112ba along the second direction Y, or both are opposite to the water supplement port 112a along the second direction Y, or both are opposite to the second exhaust port 112bb along the second direction Y.

[0068] In the above scheme, the first microchannel 151 and the second microchannel 152 can both communicate with the first exhaust passage 142, or the first microchannel 151 and the second microchannel 152 can both communicate with the first exhaust water supplement passage 141, or the first microchannel 151 and the second microchannel 152 can both communicate with the third exhaust water supplement passage 143, thereby being arranged so as not to affect the balance pressure of the first microchannel 151 and the second microchannel 152 connecting the corresponding second flow channel 130 and the exhaust water supplement passage 140, and not to affect the detection of internal leakage in the independent operation mode of each circuit, greatly improving the convenience of use.

[0069] In specific embodiments, the first micro-hole 151a and the second micro-hole 152a are spaced apart along the first direction X, the first micro-hole 151a can be opposite to the water supplement port 112a along the second direction Y, the second micro-hole 152a can be opposite to the second exhaust port 112bb along the second direction Y, or the first micro-hole 151a is opposite to the first exhaust port 112ba along the second direction Y, and the second micro-hole 152a is opposite to the second exhaust port 112bb along the second direction Y.

[0070] In the above scheme, the two microchannels 150, i.e., the first microchannel 151 and the second microchannel 152, can respectively communicate with any two of the second exhaust water supplement passage 142, the third exhaust water supplement passage 143, and the first exhaust water supplement passage 141, which can solve the problem of liquid leakage between different circuits faced by each cooling liquid circuit, the problem of liquid level difference or even gas backflow into the circuit formed in the two kettle cavities, and the problem of affecting the detection of internal leakage in the independent operation mode of each circuit, which helps to identify and avoid the related risks of internal leakage in the flow channel of the product.

[0071] In other embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The microchannel 150 includes a first section 150a and a second section 150b, one end of the first section 150a communicates with the corresponding second flow channel 130, along the length direction of the second section 150b, the second section 150b has a first end 150ba and a second end 150bb, the first end 150ba is connected with the other end of the first section 150a, and the second end 150bb is connected with the exhaust water supplement passage 140, and the inner diameter of the second section 150b gradually decreases from the first end 150ba to the second end 150bb.

[0072] In the above scheme, the gradually tapered structure of the second section 150b can form a flow guiding effect, and the mixture of liquid and gas in the microchannel 150 enters the second section 150b through the first section 150a, and as the cross section of the passage decreases, the gas flow rate naturally increases, which can quickly gather and discharge to the exhaust water supplement passage 140, avoiding gas retention in the passage to form a gas block.

[0073] Meanwhile, the tapered structure can reduce the probability of liquid flowing through the exhaust water replenishment channel 140 entering from the second end 150bb, reduce the liquid entering the first microchannel 151 from the second end 150bb, ensure that the liquid inside the exhaust water replenishment channel 140 can be replenished or exhausted according to the predetermined route, and ensure the efficiency of water replenishment or exhaust.

[0074] As an example, the inner diameter of the second section 150b can also be gradually reduced from the second end 150bb to the first end 150ba, thereby being arranged, which can also reduce the probability of liquid flowing through the exhaust water replenishment channel 140 entering from the second end 150bb, thereby ensuring that the liquid inside the exhaust water replenishment channel 140 can be replenished or exhausted according to the predetermined route, and ensuring the efficiency of water replenishment or exhaust.

[0075] Meanwhile, the tapered structure can reduce the probability of liquid flowing through the exhaust water replenishment channel 140 entering from the second end 150bb, reduce the liquid entering the first microchannel 151 from the second end 150bb, ensure that the liquid inside the exhaust water replenishment channel 140 can be replenished or exhausted according to the predetermined route, and ensure the efficiency of water replenishment or exhaust.

[0076] In addition, the transition of the inner wall of the second section 150b of the tapered structure is smooth, and it is not easy to form fluid vortex and impurity accumulation, which can reduce the probability of blockage. During later maintenance, only reverse flushing is required to easily clean the residual impurities in the channel, without the need to disassemble the complex structure, and the flow stability and maintenance convenience are considered.

[0077] In some other embodiments, the inner diameter of each microchannel 150 is d, which satisfies: 1mm≤d≤3mm.

[0078] In the above scheme, since the inner diameter of the microchannel 150 satisfies the above range, on the one hand, it can avoid too large gas-liquid flow resistance caused by too narrow channel, ensure that the mixture of liquid and gas is quickly gathered and discharged under the assistance of the tapered structure, and the liquid flows smoothly, meet the flow demand of water replenishment and exhaust, on the other hand, it can reduce the occupied space, make the overall structure more compact, avoid interference with other flow channels, reduce the probability of liquid flowing through the exhaust water replenishment channel 140 entering from the second end 150bb, reduce the liquid entering the first microchannel 151 from the second end 150bb, ensure that the liquid inside the exhaust water replenishment channel 140 can be replenished or exhausted according to the predetermined route, and ensure the efficiency of water replenishment or exhaust.

[0079] Meanwhile, since the inner diameter of the microchannel 150 satisfies the above range, it can not only block larger particle impurities (such as tiny dirt and residual particles) that may exist in the system from entering the channel to cause blockage, but also not cause tiny impurities to easily accumulate due to too fine channel, reduce the frequency of later maintenance, and ensure that the microchannel 150 is long and unobstructed.

[0080] In addition, the compact layout of the plurality of micro-channels 150 in the flow channel plate 100 can be achieved without causing structural redundancy due to excessive space occupation of the channel inner diameter, or causing machining interference due to excessively small channel spacing.

[0081] In addition, the occurrence of deformation of excessively thin channels and large size fluctuations of excessively thick channels can be reduced, ensuring the performance consistency of each micro-channel 150 and improving the stability and reliability of batch production of products.

[0082] In specific embodiments, the inner diameter of each micro-channel 150 can be the same everywhere, that is, the inner diameter of each micro-channel 150 is fixed and unchangeable, which helps to reduce the space occupation in the flow channel plate 100, reduce the probability of leakage between the micro-channels 150 and other flow channels, and reduce the probability of liquid impact on the inner wall of the channel.

[0083] Alternatively, the inner diameter of each micro-channel 150 can be partially the same, that is, the inner diameter of each micro-channel 150 is within a fixed range, so that the inner diameters at different positions in the micro-channel 150 are different, which is convenient for adapting to the compact structure in the flow channel plate 100, and helps to achieve a compact layout of a plurality of micro-channels 150 in the flow channel plate 100. By this arrangement, it is convenient to design the inner diameter of each micro-channel 150 according to the thermal management requirements of the circuit it is in, and to ensure that the pressure in different thermal management circuits can be quickly balanced with the pressure in the exhaust water supplement channel 140.

[0084] Alternatively, the inner diameter of part of the micro-channels 150 is the same everywhere, and the inner diameter of part of the micro-channels 150 is within a fixed range, and the second section 150b of each micro-channel 150 is arranged on the first end wall 112. By this arrangement, the micro-channels 150 with the same inner diameter can ensure that the pressure of the second flow channel 130 connected thereto is balanced with the exhaust water supplement channel 140, and can quickly balance the pressure difference when the thermal management mode is frequently switched. The micro-channels 150 with the inner diameter within a fixed range can reduce the space occupation in the plate body 110 as needed, which can reduce the liquid flowing in the micro-channels 150 on the one hand, reduce the probability of leakage of the micro-channels 150, reduce the influence of the liquid in the micro-channels 150 on the heat of the entire thermal management module, and on the other hand, facilitate the avoidance of other flow channels in the plate body 110, which helps to improve the integration.

[0085] Alternatively, the inner diameter of each micro-channel 150 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.3mm, 2.5mm, 2.7mm, 2.9mm, 3mm.

[0086] In other embodiments, the first flow channel 120 is used to supplement liquid for the electric drive circuit.

[0087] In some specific embodiments, the plurality of second flow channels 130 includes a first sub-flow channel 131 for supplementing the battery circuit with liquid and a second sub-flow channel 132 for supplementing the heating circuit with liquid.

[0088] It can be understood that the electric drive circuit needs a more efficient liquid supplementing circulation due to a large amount of heat generated, and the battery circuit has higher requirements for the purity and flow stability of the liquid supplement. By supplementing the electric drive circuit through the first flow channel 120, supplementing the battery circuit through the first sub-flow channel 131, and supplementing the heating circuit through the second sub-flow channel 132, it can ensure that each circuit can obtain liquid supply that is adapted to its working condition, which helps to ensure the reliability of motor heat dissipation, battery temperature control, and heating.

[0089] At the same time, the separate design of the first flow channel 120, the first sub-flow channel 131, and the second sub-flow channel 132 realizes the mutual independence of the liquid supplement of each circuit, avoids interference between different circuits due to differences in liquid supplementing requirements, and facilitates decoupling of different circuits, reducing the risk of mutual interference of fluid media of different temperatures in each circuit, making the gas-liquid separation of each circuit more thorough, and helping to improve the exhaust effect.

[0090] In addition, independent separate circuits make system maintenance more efficient. If a circuit (such as the heating circuit) has abnormal liquid supplementing or is blocked, it can be individually repaired for the corresponding flow channel without affecting the normal operation of key circuits such as the motor and the battery, greatly reducing maintenance time and cost.

[0091] Therefore, the internal space of the flow channel plate 100 can be fully utilized, the compactness of the overall structure is maintained, the reliability and efficiency of liquid supplementing during the collaborative operation of multiple systems are ensured, and the detection of internal leakage in the independent operation mode of each circuit is facilitated, avoiding quality risks caused by internal leakage.

[0092] In other specific embodiments, the flow channel plate 100 is provided with a first five-way valve (not shown in the figure) and a second five-way valve (not shown in the figure). The first flow channel 120 selectively communicates with the first sub-flow channel 131 through the first five-way valve (not shown in the figure), and the first flow channel 120 communicates with the second sub-flow channel 132 through the first five-way valve (not shown in the figure) and the second five-way valve (not shown in the figure).

[0093] Specifically, the plate body 110 is provided with a plurality of external interfaces, and the plurality of external interfaces respectively communicate with the first flow channel 120 and part of the inlets and outlets in the plurality of second flow channels 130, so that the plurality of flow channels isolated from each other can selectively communicate or independently operate. At the same time, the first five-way valve (not shown in the figure) and the second five-way valve (not shown in the figure) can be fixedly arranged on the plate body 110 by a bolt or other fixing means, which is not limited in the present application.

[0094] As an example, the first five-way valve and the second five-way valve each include a valve body and a valve core, the valve body has a plurality of passages inside, each passage is connected with an outlet of a different inlet, and the valve core can change the passage of the fluid by rotating, when the valve core rotates, the fluid enters the valve body from one inlet and then flows to another outlet through the flow channel of the valve core.

[0095] In the above scheme, different working conditions can be realized by the flow channel switching capability of the first five-way valve and the second five-way valve. When the motor is under high load and needs to be cooled, the battery needs to be temperature controlled, the heating system needs to be turned on in winter, or multiple systems need to work together, the first flow channel 120 and the first sub-flow channel 131 can be precisely controlled by the first five-way valve according to the actual running scene of the vehicle, and the first flow channel 120 and the second sub-flow channel 132 can be connected on demand by the linkage adjustment of the first five-way valve and the second five-way valve. This can not only supply liquid to the motor circuit alone, but also simultaneously meet the liquid supply demand of multiple circuits, avoid the functional limitations caused by single flow channel control, and ensure that each system can discharge and supply liquid as needed under different working conditions.

[0096] Meanwhile, the cooperation of the first five-way valve and the second five-way valve realizes the independent controllability and non-interference of each circuit liquid supply. The liquid supply paths of the motor circuit, the battery circuit, and the heating circuit can be completely separated by valve switching, avoiding the mutual influence caused by pressure fluctuations and flow differences between different circuits. At the same time, the pressure is balanced by the micro-channel 150 to ensure that the gas-liquid separation and air supply and discharge functions of each circuit are not disturbed by other circuits.

[0097] In addition, compared with the combined design of multiple single-way valves or three-way valves, the integration of two five-way valves is higher, which can greatly reduce the number of valves and connecting pipelines on the flow channel plate 100, simplify the internal structure layout of the flow channel plate 100, make full use of the limited space, avoid installation interference caused by flow channel crossing and winding, reduce the processing and assembly difficulty, and facilitate quick positioning of the fault circuit through the valve during later maintenance. It is convenient to close the corresponding valve to check the liquid supply abnormality of a certain circuit, without disassembling the entire flow channel system, which greatly improves the maintenance efficiency, and takes into account the functional diversity and practicality.

[0098] In the second aspect, referring to Figure 4 The embodiment of the present application provides a kettle integrated module 1000, which comprises the flow channel plate 100 and the expansion kettle 200.

[0099] The expansion kettle 200 is arranged on the flow channel plate 100, and the expansion kettle 200 is communicated with the air discharge and water supply passage 140.

[0100] In the above scheme, the integration of the flow channel plate 100 and the expansion water kettle 200 greatly simplifies the number of parts and the connecting pipeline, avoids the scattered installation of the flow channel, the water kettle and the pipeline in the traditional separate layout, reduces the space occupation, makes the overall structure of the module more compact, reduces the leakage risk caused by the pipeline connection, avoids the installation interference caused by the cross winding of the pipeline, and facilitates the arrangement in the limited space of the vehicle.

[0101] At the same time, the expansion water kettle 200 is directly communicated with the exhaust water supplement channel 140, the liquid in the microchannel 150 can directly meet the liquid inside the expansion water kettle 200, and the liquid in the expansion water kettle 200 can be quickly supplemented to the motor, the battery, the heating circuit and the like through the exhaust water supplement channel 140, so as to ensure that each circuit always maintains a proper liquid level and pressure.

[0102] As an example, the water kettle integrated module 1000 is further provided with a motor water pump, a battery water pump and a heating water pump, the motor water pump is arranged in the motor circuit and communicated with the first flow channel 120, the battery water pump is arranged in the battery circuit and communicated with the first sub-flow channel 131, and the heating water pump is arranged in the heating circuit and communicated with the second sub-flow channel 132.

[0103] In a specific embodiment, the expansion water kettle 200 has a first exhaust cavity, a water supplement cavity and a second exhaust cavity, after the expansion water kettle 200 is installed to the first end wall 112, the first exhaust port 112ba and the first micro hole 151a are simultaneously communicated with the first exhaust cavity, the second micro hole 152a and the water supplement port 112a are simultaneously communicated with the water supplement cavity, and the second exhaust port 112bb is communicated with the second exhaust cavity.

[0104] In a third aspect, the embodiments of the present application provide a vehicle comprising the flow channel plate 100 or the water kettle integrated module 1000 according to any one of the embodiments.

[0105] According to the vehicle provided by the third aspect of the present application, since the flow channel plate 100 or the water kettle integrated module 1000 according to any one of the embodiments is included, the internal leakage in the independent operation mode of each circuit can be detected, the quality risk caused by the internal leakage is avoided, the reliability is improved, and the user experience is improved.
