Description

[Technical Field]

[0001] The present invention relates to the technical field of vehicles, in particular to thermal management integrated modules and electric vehicles. [Background technology]

[0002] Electric vehicles often require multiple thermal management components according to the overall vehicle thermal management principle, such as an expansion water tank, at least two or more cooling water pumps, a heat exchanger, a water-cooled condenser, at least two or more water temperature sensors, a four-way solenoid valve, a three-way solenoid valve, and cooling connection pipes. In order to improve the driving range of electric vehicles, the requirements for the overall vehicle thermal management design are becoming more and more, and the number of required thermal management components is also increasing. In the prior art, The patent discloses an automotive air conditioning system including a cavity 1, an air duct 2, an air outlet 3, a heater 4, a filter 5, a blower 6, a compressor 7, a condenser 8, an evaporator 9, and a liquid storage dryer 10. Within the cavity 1, the condenser 8, the blower 6, and the evaporator 9 are arranged in this order along the air flow direction. The blower 6 is fixed between the condenser 8 and the evaporator 9, and the condenser 8 and the evaporator 9 are connected by copper pipes to form a circulating cooling circuit. The liquid storage dryer 10 is further provided on the path from the condenser 8 to the evaporator 9, and the compressor 7 is provided on the path from the evaporator 9 to the condenser 8 (see paragraph 0015 and Figure 1 of the specification of Patent Document 1). These thermal management components are distributed, occupying a large amount of installation space. The distributed configuration requires the use of a large number of cooling pipes to connect the thermal management components. The tradeoffs of the large number of cooling pipes are the complexity of the cabin, difficulty in installation, and high costs. Furthermore, the distributed configuration increases the length of the cooling connection pipes and air conditioning pipes, which further increases the system's flow resistance and heat leakage value. To meet system requirements, a more powerful water pump is required, which prolongs the PTC heating time or increases the PTC heating power, resulting in increased system costs. Therefore, developing a new thermal management integrated module that saves cost, reduces weight, and reduces installation space is a technical issue that needs to be resolved as soon as possible.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are illustrated in the accompanying drawings, the present disclosure can be realized in various ways and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are provided to enable a more complete understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0026] In existing vehicle thermal management systems, thermal management components are distributed, resulting in the following problems: (1) The length of the cooling and air conditioning piping increases, raising the system's flow resistance and necessitating the use of a high-power water pump to meet the system's requirements. (2) The increased length of the cooling and air conditioning piping also increases the system's heat leakage value, necessitating the use of a longer PTC heating time or increased PTC heating power to meet the system's heating demand. (3) Thermal management components such as the expansion water can, motor water pump assembly, battery water pump assembly, heat exchanger, water-cooled condenser, water temperature sensor, two four-way solenoid valves, three-way solenoid valve, two-way proportional valve, air conditioning electronic expansion valve, and air conditioning piping are distributed and connected via cooling and air conditioning piping, resulting in complex layout requirements. (4) The above thermal management components are supplied by different suppliers and assembled at the base, lengthening the labor hours and creating management challenges for suppliers. (5) The need for a large number of cooling and air conditioning piping increases the overall cost and weight of the vehicle.

[0027] To solve or at least partially solve the above technical problems, an embodiment of the present invention proposes a thermal management integrated module. FIG. 1 is a schematic diagram showing a configuration of an integrated thermal management module 100 according to one embodiment of the present invention, as viewed from one side thereof. FIG. 2 is a schematic diagram showing the configuration of the integrated thermal management module 100 shown in FIG. 1, as viewed from the other side thereof. FIG. 6 is a schematic diagram showing the configuration of the integrated thermal management module 100 according to another embodiment of the present invention, as viewed from one side thereof. FIG. 7 is a schematic diagram showing the configuration of the integrated thermal management module 100 shown in FIG. 6, as viewed from the other side thereof. Referring to FIGS. 1, 2, 6, and 7, the integrated thermal management module 100 may generally include a multi-channel integration plate 110 and at least two thermal management elements. The multi-channel integration plate 110 has a plurality of cooling connection conduits 111 (e.g., water channels) formed therein, allowing the multi-channel integration plate 110 to function as a connecting passage between different thermal management elements and as a carrier for the entire integrated thermal management module 100, thereby carrying the thermal management elements. The at least two thermal management elements are attached to the multi-channel integration plate 110 and are connected to each other via cooling connection lines within the multi-channel integration plate 110 .

[0028] The thermal management integrated module 100 of the present embodiment employs a multi-channel integration plate 110 design, which includes multiple cooling connection ducts 111 that function not only as connecting passages between different thermal management components but also as a carrier for the entire integrated module. Thermal management components can be integrated into the multi-channel integration plate 110, resulting in a low-cost, lightweight, and space-saving integrated thermal management module 100. The use of the cooling connection ducts 111 within the multi-channel integration plate 110 allows the integrated thermal management components to be connected without the need for additional connecting ducts, thereby reducing costs and improving the aesthetics of the cabin. Furthermore, because the thermal management components are integrated into the multi-channel integration plate 110 to form an integrated module, the thermal management integrated module 100 of the present invention can be supplied modularized, significantly optimizing supplier management and production efforts.

[0029] The multi-channel integration plate 110 is an important component of the thermal management integrated module 100 of the present invention. The cooling connection conduits 111 within the multi-channel integration plate 110 are designed based on the connection topology of each thermal management component in the thermal management principle diagram of the entire vehicle to be actually applied, thereby realizing the conduit (e.g., water channel) connections between the thermal management components. FIG. 4 is a schematic diagram showing the configuration of the multi-channel integration plate 110 of the thermal management integrated module 100 according to one embodiment of the present invention. As shown in FIG. 4, the installation direction of each cooling connection conduit 111 within the multi-channel integration plate 110 extends substantially along the longitudinal direction of the multi-channel integration plate 110. In use, by mounting the multi-channel integration plate 110 so that its longitudinal direction is substantially parallel to the horizontal direction and its width direction is substantially perpendicular to the vehicle chassis, the flow resistance due to gravity of the coolant (e.g., water) flowing through each cooling connection conduit 111 can be minimized.

[0030] To ensure thermal insulation between the cooling connection ducts 111 and reduce heat loss, the multi-channel integration plate 110 may be made of a heat-insulating plastic such as PP (Polypropylene) or PA66 (Polyamide 66). Using a multi-channel integration plate 110 made of PP or PA66 ensures the strength of the multi-channel integration plate 110 while maintaining thermal insulation, thereby improving the structural stability and durability of the thermal management integrated module 100. To facilitate molding of the multi-channel integration plate 110, a split molding method may be used in which the multi-channel integration plate 110 is divided into a main body and a cover plate along its thickness direction, the cooling connection ducts 111 are formed in the main body, and the main body and cover plate are injection molded separately, and then the main body and cover plate are joined and fixed by welding to obtain the multi-channel integration plate 110. Welding methods include, but are not limited to, hot plate welding, friction welding, and laser welding.

[0031] The integrated thermal management components can be selected according to the thermal management components actually required for the thermal management of the entire vehicle, and their mounting positions on the multi-channel integration plate 110 can be installed according to the external shape, dimensional design, connection and operation method of the actually selected thermal management components in the thermal management principle diagram of the entire vehicle, etc. Accordingly, the fixing structures of these thermal management components are designed at the corresponding positions on the multi-channel integration plate 110.

[0032] Generally, the thermal management components integrated into the multi-channel integration board 110 include an expansion water can 120, a multi-way valve 130, a water pump 140, a heat exchanger 150, a condenser 160 (e.g., a water-cooled condenser), a temperature sensor 170, Dryer 180, an electronic expansion valve 191, a two-way proportional valve 192, an air conditioning line 190, or the like.

[0033] The specific structure of the thermal management integrated module 100 of the present invention will be described below in conjunction with an embodiment.

[0034] Example 1 In this embodiment, the multi-channel integrating board 110 has the structure shown in FIG.

[0035] As shown in FIGS. 1 and 2, in this embodiment, the thermal management components integrated into the multi-channel integrated board 110 include an expansion water can 120, a multi-way valve 130, a water pump 140, a heat exchanger 150, a water-cooled condenser 160, a temperature sensor 170, and Dryer 180, an electronic expansion valve 191, a two-way proportional valve 192, an air conditioning line 190, or the like.

[0036] When the thermal management component includes water pumps 140, the number of water pumps 140 is generally at least two, based on the thermal management principle of the entire vehicle. One water pump 140 (which may be referred to as a motor water pump) is used to drive the coolant flow in the vehicle's motor cooling circuit, and the other water pump 140 (which may be referred to as a battery water pump) is used to drive the coolant flow in the vehicle's battery pack cooling circuit. The at least two water pumps 140 can be installed on the same side of one longitudinal end of the multi-channel integration plate 110 and arranged along the width direction of the multi-channel integration plate 110. This water pump arrangement is advantageous for the installation and management of the water pumps 140 and allows for more efficient use of the installation space on the multi-channel integration plate 110. In a specific embodiment, the pump housing of the water pump 140 is cylindrical. Accordingly, as shown in FIG. 4 , a first annular fixing member is installed at the location where the water pump is fixed on the multi-channel integration plate 110. A plurality of first fixing blocks are evenly distributed around the periphery of the first fixing member and protrude in the circumferential direction, with each first fixing block having a first through-hole. A second fixing member corresponding to the first fixing member is installed at one end of the pump housing of the water pump 140. Second fixing blocks corresponding to the first fixing blocks are installed around the periphery of the second fixing member, with each second fixing block having a second through-hole corresponding to the first through-hole. During installation, fasteners (such as bolts) are inserted through the corresponding second through-holes and first through-holes to secure the water pump 140 to the multi-channel integration plate 110.

[0037] Furthermore, the thermal management member can further include an expansion water can 120, which is attached to the other side of the multi-channel integration plate 110, opposite the expansion water can 140. The expansion water can 120 has a large volume and is usually connected to one of the water pumps 140. By arranging it in this manner, the length of the cooling connection pipe 111 (connection passage) between the expansion water can 120 and the water pump 140 can be minimized, reducing flow resistance and making more effective use of the installation space on the multi-channel integration plate 110, thereby saving installation space. A pressure lid is installed on the top of the expansion water can 120.

[0038] The thermal management component may include a multi-way valve 130 (e.g., a four-way solenoid valve, a three-way solenoid valve, etc.). According to the overall vehicle thermal management principle, the ports of the multi-way valve 130 are connected to multiple thermal management components in the overall vehicle thermal management system to control the on / off of different thermal management circuits. Therefore, the multi-way valve 130 may be installed in a middle portion on one side of the multi-channel integration board 110, facilitating connection between the multi-way valve 130 and other thermal management components. Preferably, the multi-way valve 130 is a nine-way valve, which can replace one three-way solenoid valve and two four-way solenoid valves in the overall vehicle thermal management system to achieve nine passages, thereby further reducing the overall vehicle cost and weight. More preferably, the multi-way valve 130 may be an integrated nine-way valve, which has a flat mounting panel and nine flow path connections (i.e., ports) centrally arranged on the mounting panel, thereby unifying the connection port locations. An integrated nine-way valve having such a configuration can be more easily attached to the multi-channel integration plate 110, reducing the installation space occupied by the multi-way valve 130, and significantly improving the installation space and aesthetics of the distribution of the cooling connection pipes 111 communicating with these connection ports.

[0039] The thermal management member may further include a heat exchanger 150. The heat exchanger 150 is mounted adjacent to the multi-port valve 130 on the same side of the multi-channel integration plate 110 as the multi-port valve 130, thereby effectively shortening the length of the connecting pipes between the heat exchanger 150 and the ports of the multi-port valve 130. In a specific implementation, the multi-port valve 130 may be mounted on the upper side of a middle portion of the multi-channel integration plate 110 (the upper side here refers to the vertical upper side when the thermal management integrated module 100 is in use), and the heat exchanger 150 may be mounted on the lower side of the middle portion and attached to the multi-channel fixing points and the heat exchanger fixing points, as shown in FIG.

[0040] The thermal management component may further include a condenser 160 (e.g., a water-cooled condenser 160). Because the volume of the condenser 160 in the thermal management system of the entire vehicle is generally large, the condenser 160 may be installed at one end of the multi-channel integration plate 110 in the longitudinal direction, thereby ensuring sufficient installation space for the condenser 160. In addition, the condenser 160 may be located adjacent to the heat exchanger 150 on the same side of the multi-channel integration plate 110, thereby improving the utilization of the installation space. Of course, those skilled in the art will understand that if the expansion water canister 120 and the condenser 160 are integrated into the multi-channel integration plate 110 at the same time, the expansion water canister 120 and the condenser 160 may be installed at both ends of the multi-channel integration plate 110 in the longitudinal direction, thereby ensuring sufficient installation space for each of them.

[0041] The thermal management member comprises: Dryer 180, an electronic expansion valve 191, and an air conditioning line 190, and other components in the refrigerant circulation circuit of the vehicle air conditioning. Dryer The air conditioning pipe 190 is provided on the other side of the multi-channel integration plate 110, facing the heat exchanger 150. Dryer 180, an electronic expansion valve 191, a heat exchanger 150, and a condenser 160 are connected to the refrigerant circulation pipe, which realizes the circulation of the refrigerant of the air conditioning compressor. Dryer 180 is located on one side of the multi-channel integration plate 110. The number of electronic expansion valves 191 is determined based on the actual heat management principle of the entire vehicle, and may be, for example, two.

[0042] The thermal management member may further include a temperature sensor 170 attached to a designated cooling connection pipe 111 on the multi-channel integration plate 110 to measure the temperature of the coolant (e.g., water) in the designated cooling connection pipe 111. The number of temperature sensors 170 is determined based on the actual required thermal management principle diagram of the entire vehicle, and may be, for example, four.

[0043] The thermal management components may also include a two-way proportional valve 192 (not shown in FIGS. 1 and 2), which may be an intelligent proportional valve installed in the cooling connection line 111 between one of the water pumps 140 and the condenser 160.

[0044] In an embodiment of the present invention, specific integrated thermal management components (specifically, an expansion water can 120, a multi-way valve 130, a water pump 140, a heat exchanger 150, a condenser 160, a temperature sensor 170, Dryer 180, electronic expansion valve 191, air conditioning duct 190, etc.), by rationally distributing these heat management components on multi-channel integration plate 110, the arrangement of the heat management components can be made more compact, and the distribution of cooling connection ducts 111 in multi-channel integration plate 110 can be optimized, reducing manufacturing difficulties.

[0045] 1 and 2, air conditioning piping 190 is provided with air conditioning piping external connections that are arranged to connect to refrigerant connection piping of a thermally managed object related to vehicle air conditioning. Specifically, the thermally managed object related to vehicle air conditioning includes the built-in condenser and compressor of the air conditioner main body, and the air conditioning piping external connections include built-in condenser inlet connection 193, built-in condenser outlet connection 194, compressor inlet connection 195, and compressor outlet connection 196. Built-in condenser inlet connection 193 and built-in condenser outlet connection 194 are each arranged to connect to the refrigerant connection piping of the built-in condenser of the air conditioner main body of the vehicle. Compressor inlet connection 195 and compressor outlet connection 196 are each arranged to connect to the refrigerant connection piping of the compressor of the vehicle. In order to minimize the refrigerant connection lines of the built-in condenser and the compressor, the positions of the built-in condenser inlet connection port 193, the built-in condenser outlet connection port 194, the compressor inlet connection port 195, and the compressor outlet connection port 196 are distributed according to the locations of the built-in condenser and the compressor. Specifically, for example, the compressor inlet connection port 195 and the compressor outlet connection port 196 are located below the expansion water canister 120 on the same side as the expansion water canister 120, and the built-in condenser inlet connection port 193 and the built-in condenser outlet connection port 194 are located below one end of the multi-channel integration plate 110 on the same side as the condenser 160.

[0046] The air conditioning pipe external connection port may also include a built-in evaporator inlet connection port 197 arranged to connect to the refrigerant connection pipe of the built-in evaporator of the air conditioner main body. To minimize the refrigerant connection pipe of the built-in evaporator, the positions of the built-in evaporator inlet connection ports 197 are distributed according to the location of the built-in evaporator. Specifically, the built-in evaporator inlet connection port 197 is located on the same side as the condenser 160, below one end of the multi-channel integration plate 110 where the condenser 160 is located.

[0047] 1, the multi-channel integrated board 110 is further formed with a plurality of cooling pipe external connection ports. These cooling pipe external connection ports are arranged to connect to the coolant connection pipes of the thermally managed components of the vehicle, and the positions of the cooling pipe external connection ports are arranged according to the positions of the thermally managed components in order to minimize the length of the coolant connection pipes of the thermally managed components. The thermally managed components include, but are not limited to, a DC-DC converter, a high-voltage coolant heater (HVCH), an on-board charger (OBC), a battery pack, a radiator, etc.

[0048] When the thermal management integrated module 100 is considered as a whole, the corresponding objects to be thermally managed (e.g., the aforementioned DC-DC converter, HVCH, OBC, battery pack, radiator, compressor, built-in condenser and built-in evaporator of the air conditioner main body, etc.) can be regarded as mating components of the overall thermal management component 100. By carefully considering the layout positions of the mating components, the external connection ports of the cooling pipes and the external connection ports of the air conditioning pipes are uniformly installed, and the connecting pipes of the objects to be thermally managed are minimized, thereby further reducing the cost and weight of the entire vehicle.

[0049] Specifically, the cooling pipe external connection ports include a radiator liquid supply connection port 112, a radiator liquid drain connection port 113, a DC-DC converter liquid supply connection port 114, a high-pressure liquid heater liquid supply connection port 115, a high-pressure liquid heater liquid drain connection port 118, an on-board charger liquid drain connection port 116, a battery pack liquid supply connection port 119, and a battery pack liquid drain connection port 117. The radiator liquid supply connection port 112, the radiator liquid drain connection port 113, and the DC-DC converter liquid supply connection port 114 are located at one longitudinal end of the multi-channel integration plate 110 (specifically, the end where the water pump 140 is located), and the radiator liquid supply connection port 112 and the radiator liquid drain connection port 113 extend to one side of the multi-channel integration plate 110 (specifically, the end where the water pump 140 is located). The high-pressure liquid heater liquid supply connection port 115, the on-board charger liquid drain connection port 116, the battery pack liquid drain connection port 117, the high-pressure liquid heater liquid drain connection port 118, and the battery pack liquid supply connection port 119 are located at the other longitudinal end of the multichannel integration plate 110 (specifically, the other end where the condenser 160 is located), and are arranged sequentially along the width direction of the multichannel integration plate 110, with the extension direction of these being the same as the extension direction of the radiator liquid supply connection port 112. By configuring them in this way, it is possible to achieve a balance between space utilization, aesthetics, and ease of use of the connection ports.

[0050] The above has described in detail each component of the thermal management integrated module 100 of this embodiment. The principle of realizing the thermal management integrated module 100 of this embodiment will now be described with reference to FIG. 5. FIG. 5 is a schematic diagram showing the principle of the thermal management integrated module according to one embodiment of the present invention. This embodiment includes two electronic water pumps 140 (referred to as a battery water pump and a motor water pump, respectively), an integrated nine-way valve, a water-cooled condenser 160, a heat exchanger 150, an expansion water can 120, four temperature sensors 170 (water temperature sensors), an intelligent two-way proportional valve 192, two electronic expansion valves 191, Dryer180 and air conditioning ducts 190 are integrated into the multi-channel integration plate 110. The integrated nine-way valve in FIG. 5 corresponds to two four-way solenoid valves and one three-way solenoid valve, and the numbers 1 to 9 represent the nine ports of the integrated nine-way valve. Solid lines indicate the cooling connection ducts 111 in the multi-channel integration plate 110, and the arrows on the solid lines indicate the flow of coolant through the cooling connection ducts 111. Dotted lines indicate the air conditioning ducts 190, and the arrows on the dotted lines indicate the flow of refrigerant through the air conditioning ducts 190. Connections between each thermal management component as shown in FIG. 5 are realized via the cooling connection ducts 111 and air conditioning ducts 190 in the multi-channel integration plate 110. By providing multiple cooling duct external connection ports and air conditioning duct external connection ports as shown in FIG. 5, different thermal management circuits are formed.

[0051] Example 2 The main differences between the second embodiment and the first embodiment are as follows.

[0052] The thermal management components associated with the refrigerant circulation circuit of the vehicle air conditioning integrated into the multi-channel integration board 110 include: Dryer 6 and 7, the electronic expansion valve 191 is attached to the multi-channel integration plate 110 at the same side as the heat exchanger 150 and at a position adjacent to the heat exchanger 150, and the air conditioning pipe 190 is connected to the electronic expansion valve 191, the heat exchanger 150, and the condenser 160. The main body of the air conditioning duct 190 extends on one side of the multi-channel integrated plate 110 where the expansion water canister 120 is located, and forms a compressor outlet connection port 196 located below the expansion water canister 120 on the same side as the expansion water canister 120. The built-in condenser outlet connection port 194 is formed on the valve seat of the electronic expansion valve 191. The built-in condenser inlet connection port 193 and the compressor inlet connection port 195 are formed on the water-cooled condenser 160 and the heat exchanger 150, respectively, which effectively shortens the length of the air conditioning duct 190 and the length of the connecting ducts between the compressor and the built-in condenser and their corresponding connections.

[0053] As shown in Figures 8a and 8b, the multi-channel integration plate 110 in this embodiment is provided with a plurality of mounting ears 198, which are arranged to mount and secure the thermal management integrated module 100 to the vehicle body. Each mounting ear 198 protrudes outward from the edge of the multi-channel integration plate 110 and includes a base portion connected to the edge of the multi-channel integration plate 110 and a head portion spaced from the multi-channel integration plate 110. The head portion has a central through-hole that cooperates with a fastener that can pass through the central through-hole to mount and secure the thermal management integrated module 100 to the vehicle body. To ensure the robustness of the mounting, the number of mounting ears 198 is at least three, preferably three, and the three mounting ears 198 are respectively located on the three edges of the multi-channel integration plate 110. Furthermore, a ring-shaped cushion pad can be installed within the central through-hole of each mounting ear 198, with the cushion pad's thickness being greater than the thickness of the head portion of the mounting ear 198 and the surface of the cushion pad protruding from the central through-hole. After the multi-channel integrated board 110 is attached to the body of a vehicle, the cushion pad can cushion the impact between the attachment ear 198 and the body part of the vehicle to which it is attached. The cushion may be made of rubber.

[0054] In this embodiment, the expansion water can 120 is previously integrated with the multi-channel integration plate 110 by hot plate welding or the like.

In this embodiment, two electronic water pumps 140 (referred to as a battery water pump and a motor water pump, respectively), an integrated nine-way valve, a water-cooled condenser 160, a heat exchanger 150, an expansion water tank 120, four temperature sensors 170 (water temperature sensors), an intelligent two-way proportional valve 192, one electronic expansion valve 191, and an air conditioning line 190 are integrated into a multi-channel integration board 110. The integrated nine-way valve in FIG. 9 corresponds to two four-way solenoid valves and one three-way solenoid valve, and the numbers 1 through 9 represent the nine ports of the integrated nine-way valve. Solid lines indicate the cooling connection lines 111 on the multi-channel integration board 110, and the arrows on the solid lines indicate the flow of coolant through the cooling connection lines 111. Dotted lines indicate the air conditioning line 190, and the arrows on the dotted lines indicate the flow of refrigerant through the air conditioning line 190. Connections between the various thermal management components shown in Figure 9 are realized via the cooling connection pipes 111 and air conditioning pipes 190 in the multi-channel integration board 110, and different thermal management circuits are formed by providing multiple cooling pipe external connection ports and air conditioning pipe external connection ports shown in Figure 9 (specifically, radiator liquid supply connection port 112, radiator liquid drain connection port 113, DC-DC converter liquid supply connection port 114, high-pressure liquid heater liquid supply connection port 115, high-pressure liquid heater liquid drain connection port 118, on-board charger liquid drain connection port 116, battery pack liquid supply connection port 119, battery pack liquid drain connection port 117, built-in condenser inlet connection port 193, built-in condenser outlet connection port 194, compressor inlet connection port 195, and compressor outlet connection port 196).
