Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy thermal management integration technology, specifically to a thermal management module for hybrid electric vehicles. Background Technology
[0002] Currently, the main structure of thermal management integrated modules in the new energy field mainly includes a kettle, flow channel plate assembly, heat exchanger assembly, water pump, multi-way water valve, etc. Coolant enters the kettle through the flow channel outlet, and then enters the flow channel through the kettle outlet for loop circulation; at the same time, the coolant can exchange heat with the internal and external loop liquids or refrigerants through the heat exchanger to achieve temperature regulation within the system.
[0003] The inventors discovered that the existing thermal management module's reservoir structure causes excessive noise inside the reservoir due to the large flow of coolant directly impacting the top surface of the reservoir after it enters. This affects the NVH (Noise, Vibration, and Harshness) performance of the thermal management integrated module. Utility Model Content
[0004] To address the technical problem of excessive noise during operation of existing thermal management integrated modules in the new energy field, this utility model provides a thermal management module for hybrid vehicles. A flow guiding and diverting structure is provided at the first inlet of the middle plate to guide the coolant flow entering the reservoir into the parallel first and second inlet channels on the middle plate. This prevents the coolant from directly impacting the top surface of the reservoir, thereby reducing the noise during operation of the thermal management integrated module in the new energy field and optimizing its NVH performance.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model provides a thermal management module for hybrid electric vehicles, including a mid-plate body. The mid-plate body is provided with a first mid-plate inlet, a first mid-plate outlet, a first mid-plate flow channel, and a second mid-plate flow channel. One end of each of the first and second mid-plate flow channels is connected to the first mid-plate outlet. The first mid-plate inlet is adapted to a flow guiding and diverting structure, which includes a lateral blocking part and a vertical dividing part. The lateral blocking part is located at the front end of the first mid-plate inlet in the inlet direction. The vertical dividing part is vertically arranged in the first mid-plate inlet, and the two cavities separated by the vertical dividing part are respectively connected to the corresponding first and second mid-plate flow channels.
[0007] It should be noted that in existing new energy thermal management integrated module flow channel plate assemblies, after the coolant enters the reservoir, the large flow rate of coolant directly impacts the top surface of the reservoir, resulting in excessive noise from the reservoir and affecting the NVH performance of the thermal management integrated module. Furthermore, the inventors' research has found that in existing flow channel plate assemblies, when a large flow rate of coolant directly enters the reservoir, the excessive impact force of the water flow causes the coolant to continuously churn, keeping the coolant in a turbid state for a long time and generating a large number of bubbles. This makes it difficult for the gas to escape, significantly reducing exhaust efficiency.
[0008] In view of this, the thermal management module for hybrid electric vehicles provided by this utility model includes a middle plate body. The middle plate body is provided with a first middle plate inlet, a first middle plate outlet, a first middle plate flow channel, and a second middle plate flow channel. One end of the first middle plate flow channel and the second middle plate flow channel are both connected to the first middle plate outlet. At the same time, the first middle plate inlet is adapted with a lateral blocking part and a vertical dividing part. The lateral blocking part is located at the front end of the first middle plate inlet in the liquid inlet direction. The two cavities separated by the vertical dividing part are respectively connected to the corresponding first middle plate flow channel and the second middle plate flow channel, thereby making the first middle plate flow channel and the second middle plate flow channel connected in parallel.
[0009] When the coolant in the new energy thermal management integrated system enters the cavity formed by the middle plate and the kettle body through the inlet of the first middle plate, the transverse baffles cause the coolant to flow towards the side wall of the cavity. This reduces the impact force of the coolant entering the kettle, preventing it from directly impacting the top surface of the kettle. The coolant also acts as a buffer within the kettle, significantly reducing noise caused by the water flow. Furthermore, after entering the cavity through the inlet of the first middle plate, the coolant simultaneously flows through the first and second middle plate inlet channels, dispersing the impact force and preventing the coolant from "tumbling" within the kettle. This greatly reduces air bubbles generated during the coolant impact process and improves the venting efficiency of the coolant in the kettle.
[0010] The horizontal blocking part and the vertical dividing part are located at the liquid inlet of the first middle plate. They can be integrally formed with the middle plate body without the need for additional parts. They can guide and divert the liquid at the same time, and have the characteristics of simple structure and low cost.
[0011] In an optional embodiment of this application, a plurality of first sinks are provided at the bottom of the first middle plate inlet channel, and the plurality of first sinks are arranged sequentially at intervals along the flow direction of the first middle plate inlet channel.
[0012] Existing new energy thermal management integrated modules lack filtration components, failing to filter coarse particulate impurities in the coolant. The flow channel plate assembly provided by this invention features multiple first settling tanks arranged sequentially and at intervals along the flow direction of the first middle plate inlet channel. This allows the coolant to flow through these tanks sequentially as it moves through the reservoir, causing denser impurities to settle within them, achieving multi-stage sedimentation and thus filtering out coarse particulate impurities. Furthermore, the first settling tanks can be integrally formed with the middle plate body, achieving three-stage filtration without the need for additional components.
[0013] In an optional embodiment of this application, a plurality of second settling tanks are provided at the bottom of the inlet channel of the second middle plate, and the plurality of second settling tanks are arranged sequentially at intervals along the flow direction of the inlet channel of the second middle plate. Similarly, when the coolant flows in the kettle, it flows through the plurality of second settling tanks in sequence, so that the higher density impurities in the coolant settle in the second settling tanks to achieve multi-stage sedimentation, thereby filtering out coarse particulate impurities in the coolant and preventing impurities from circulating with the coolant in the new energy thermal management integration. Moreover, the second settling tanks can be integrally formed with the middle plate body, and three-stage filtration can be achieved without the need for additional separate parts.
[0014] In an optional embodiment of this application, the water tank body is further included. The water tank body is provided with a first venting chamber and a second venting chamber in parallel. Both the first venting chamber and the second venting chamber are sloping top structures, so that when the coolant flows in the water tank, the air bubbles in the coolant can be quickly guided to the top of the water tank surface, thereby accelerating the venting effect and avoiding "air trapping" in the coolant.
[0015] In an optional embodiment of this application, the kettle body is provided with a flow channel adapted to the upper end of the middle plate, and the top of the kettle body is provided with a first exhaust structure and a second exhaust structure; the inlet end of the first exhaust structure is provided with a first water-blocking part at intervals, and the inlet end of the second exhaust structure is provided with a second water-blocking part at intervals.
[0016] Therefore, when the coolant flows through the first exhaust structure, it directly impacts the first water baffle, allowing the coolant to absorb the impact of the coolant flow through the first water baffle and the surrounding coolant, thus reducing the impact of the coolant flow and dispersing the large flow of water into many small flows. At the same time, when the coolant flows through the second exhaust structure, it directly impacts the second water baffle, allowing the coolant to absorb the impact of the coolant flow through the second water baffle and the surrounding coolant, thus reducing the impact of the coolant flow and dispersing the large flow of water into many small flows. This avoids the large flow of water directly impacting the liquid surface and generating a lot of noise, further optimizing the NVH performance of the thermal management integrated module.
[0017] In an optional embodiment of this application, the kettle body is provided with a sight glass to facilitate observation of the coolant level inside the kettle.
[0018] In an optional embodiment of this application, the top of the kettle body is provided with a spout and a guide channel. The guide channel includes a liquid collection section and a guide section that communicate with each other. The liquid collection section is arranged around the connection between the spout and the top of the kettle body, and the guide section is arranged on the side wall of the kettle body.
[0019] Existing flow channel plate assemblies lack drainage structures on the outer surface of the kettle. When water is added or the kettle lid experiences abnormal pressure release, leaked coolant drips down the outer surface and seeps into electrical components, potentially causing a short circuit. This invention, however, incorporates a flow guide groove at the top of the kettle body. When coolant is added or water droplets fall onto the kettle body, they converge along the collection section to the flow guide section, then are directed to the side of the integrated module to bypass electrical components, thus reducing the risk of short circuits in the electrical components below the flow channel plate assembly. Furthermore, the flow guide groove can be integrally molded with the kettle body, eliminating the need for additional complex parts and processing costs, improving product reliability and reducing the risk of failure.
[0020] In an optional embodiment of this application, a motherboard body is further included, wherein the upper end of the motherboard body is provided with a flow channel that adapts to the lower end of the middle plate body, and the motherboard body is adapted to a mounting bracket.
[0021] In an optional embodiment of this application, the mounting bracket is provided with a reinforcing rib structure. The reinforcing rib structure is a porous structure, which can effectively strengthen the thermal management integrated module in several directions such as up and down, front and back, left and right, and improve the overall aesthetics of the module.
[0022] In an optional embodiment of this application, the middle plate, the kettle body, and the main plate are all provided with welding positioning holes, so that when the flow channel plate assembly is welded and assembled, only matching positioning pins need to be made on the welding fixture for effective positioning, thereby significantly improving the welding accuracy of the kettle body and the middle plate, and the middle plate and the main plate when plastic welding, effectively avoiding the problem of misalignment of the welding surfaces during welding, and thus improving the reliability of product welding and the product welding qualification rate.
[0023] In an optional embodiment of this application, the motherboard body is provided with a first motherboard liquid inlet, which is connected to a water pump.
[0024] In an optional embodiment of this application, the main board body is further provided with a first main board liquid outlet, a second main board liquid inlet, a fourth main board liquid outlet, and a fifth main board liquid inlet; the first main board liquid outlet is connected to the first medium-side inlet of the water-water heat exchanger, the second main board liquid inlet is connected to the first medium-side outlet of the water-water heat exchanger, the fourth main board liquid outlet is connected to the second medium-side inlet of the water-water heat exchanger, and the fifth main board liquid inlet is connected to the second medium-side outlet of the water-water heat exchanger.
[0025] In an optional embodiment of this application, a second motherboard liquid outlet and a third motherboard liquid inlet are further provided on the motherboard body; the second motherboard liquid outlet is connected to a medium interface of the battery heat exchanger assembly, and the third motherboard liquid inlet is connected to a medium interface of the battery heat exchanger assembly.
[0026] In an optional embodiment of this application, the water-to-water heat exchanger, the water pump, and the battery heat exchanger assembly are all suspended on the lower side of the main body to facilitate venting of the heat exchanger flow channel, ensure the heat exchange efficiency of the heat exchanger, and at the same time facilitate water replenishment for the water pump, greatly reducing the possibility of the water pump running dry.
[0027] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0028] 1. The thermal management module for hybrid electric vehicles provided by this utility model has a first mid-plate inlet, a first mid-plate outlet, a first mid-plate flow channel, and a second mid-plate flow channel in the mid-plate body. One end of each of the first and second mid-plate flow channels is connected to the first mid-plate outlet. The first mid-plate inlet is equipped with a transverse blocking part and a vertical dividing part. The transverse blocking part is located at the front end of the inlet in the direction of liquid inflow of the first mid-plate inlet. The two cavities separated by the vertical dividing part are respectively connected to the corresponding first and second mid-plate flow channels. Thus, the first and second mid-plate flow channels are connected in parallel. Through the blocking effect of the transverse blocking part, the coolant flows to the side wall of the cavity formed by the mid-plate body and the reservoir body, thereby reducing the impact force of the coolant after entering the reservoir and preventing the coolant from directly impacting the top surface of the reservoir. The coolant in the reservoir provides buffering, thereby greatly reducing the noise caused by the impact of the water flow in the reservoir.
[0029] 2. The thermal management module for hybrid electric vehicles provided by this utility model has two cavities separated by a vertical partition, which are respectively connected to the first and second middle plate inlet channels. This allows the coolant in the new energy thermal management integrated system to enter the cavity formed by the middle plate and the reservoir body from the first middle plate inlet, and then flow through the first and second middle plate inlet channels. This disperses the impact force of the coolant and prevents the coolant from "rolling" in the reservoir, thereby greatly reducing the air bubbles generated during the coolant impact and improving the venting efficiency of the coolant in the reservoir.
[0030] 3. The thermal management module for hybrid electric vehicles provided by this utility model has a horizontal blocking part and a vertical dividing part set at the liquid inlet of the first middle plate. It can be integrally formed with the middle plate body without the need for additional separate parts. It can simultaneously guide and divert the liquid, and has the characteristics of simple structure and low cost. Attached Figure Description

[0056] Example
[0057] Combination Figure 4This embodiment provides a thermal management module for a hybrid electric vehicle, including a mid-plate body 200. The mid-plate body 200 is provided with a first mid-plate inlet 201, a first mid-plate outlet 202, a first mid-plate inlet channel 203, and a second mid-plate inlet channel 204. One end of the first mid-plate inlet channel 203 and the second mid-plate inlet channel 204 are both connected to the first mid-plate outlet 202. The first mid-plate inlet 201 is adapted to a flow guiding and diverting structure, which includes a lateral blocking part 205 and a vertical dividing part 206. The lateral blocking part 205 is located at the front end of the first mid-plate inlet 201 in the inlet direction. The vertical dividing part 206 is vertically arranged in the first mid-plate inlet 201, and the two cavities separated by the vertical dividing part 206 are respectively connected to the corresponding first mid-plate inlet channel 203 and second mid-plate inlet channel 204.
[0058] Combination Figure 1 It should be understood that the flow channel plate assembly of the new energy thermal management integrated module includes a main board 100, a middle board 200, and a coolant tank 300. The main board 100, middle board 200, and coolant tank 300 are made of weldable plastic injection molding to facilitate the processing and manufacturing of the new energy thermal management integrated module. Multiple flow channels are provided within the main board 100, middle board 200, and coolant tank 300 to meet the coolant flow direction control requirements of the new energy thermal management integrated system.
[0059] The middle plate 200, the kettle body 300, and the main plate 100 are all provided with welding positioning holes. When the flow channel plate assembly is welded and assembled, only matching positioning pins need to be made on the welding fixture for effective positioning. This significantly improves the welding accuracy of the kettle body 300 and the middle plate 200, and the middle plate 200 and the main plate 100 during plastic welding, effectively avoids the problem of misalignment of welding surfaces during welding, and thus improves the reliability of product welding and the product welding qualification rate.
[0060] It should be understood that this embodiment also includes a water-to-water heat exchanger 500, a water pump 600, and a battery heat exchanger assembly 700. Preferably, the water-to-water heat exchanger 500, the water pump 600, and the battery heat exchanger assembly 700 are all suspended on the lower side of the main body 100 to facilitate venting of the heat exchanger flow channels, ensure the heat exchange efficiency of the heat exchanger, and at the same time, facilitate water replenishment for the water pump 600, greatly reducing the possibility of the water pump 600 running dry.
[0061] The specific structure of the thermal management module for hybrid vehicles provided in this embodiment is as follows:
[0062] Combination Figure 2The upper end of the main board body 100 is provided with a flow channel that adapts to the lower end of the middle board body 200. Specifically, the main board body is provided with a first main board liquid inlet 103, a first main board flow channel 104, a first main board liquid outlet 105, a second main board liquid inlet 106, a second main board flow channel 107, a second main board liquid outlet 108, a third main board liquid inlet 109, a third main board flow channel 110, a fourth main board liquid inlet 111, a fourth main board flow channel 112, a fourth main board liquid outlet 113, a fifth main board liquid inlet 114, a fifth main board flow channel 115, a fifth main board liquid outlet 116, a sixth main board flow channel 117, a sixth main board liquid outlet 118, a first main board positioning hole 119, and a second main board positioning hole 120.
[0063] The first motherboard inlet 103 is connected to the coolant circulation system, and the first motherboard inlet channel is connected to both the first motherboard inlet 103 and the first motherboard outlet 105. The first motherboard outlet 105 is also connected to the first medium-side inlet of the water-to-water heat exchanger 500. The second motherboard inlet channel 107 is connected to the second motherboard inlet 106 and the second motherboard outlet 108. The second motherboard inlet 106 is connected to the first medium-side outlet of the water-to-water heat exchanger 500, and the second motherboard outlet 108 is connected to a medium interface of the battery heat exchanger assembly 700. The third motherboard inlet channel 110 is connected to the third motherboard inlet... The liquid inlet 109 is connected to the third main board liquid inlet 109, which is connected to a medium interface of the battery heat exchanger assembly 700; the liquid inlet 111 of the fourth main board is connected to the inlet of the water pump 600; the liquid inlet channel 112 of the fourth main board is connected to the liquid outlet 113 of the fourth main board; the liquid outlet 113 of the fourth main board is connected to the second medium side inlet of the water-to-water heat exchanger 500; the liquid inlet channel 115 of the fifth main board is connected to the liquid inlet 114 and the liquid outlet 116 of the fifth main board; the liquid inlet 114 of the fifth main board is connected to the second medium side outlet of the water-to-water heat exchanger 500; and the liquid outlet 116 of the fifth main board is connected to the coolant circulation system.
[0064] It is understood that the motherboard body 100 is equipped with a mounting bracket 101 to mount the flow channel plate assembly at a designated position. Combined with... Figure 3 The mounting bracket 101 is provided with a reinforcing rib structure 102, which is a porous structure that can effectively strengthen the thermal management integrated module in several directions, including vertically, horizontally, and front-back, and improve the overall aesthetics of the module. In this embodiment, the reinforcing rib structure 102 is honeycomb-like, with each reinforcing rib radiating outwards in four directions.
[0065] Combined again Figure 4The upper end of the middle plate 200 is provided with a flow channel that adapts to the lower end of the main plate 100 and the lower end of the kettle body 300. Specifically, the middle plate 200 is provided with a first middle plate inlet 201, a first middle plate outlet 202, a first middle plate inlet channel 203, a second middle plate inlet channel 204, a second middle plate outlet 209, a third middle plate inlet channel 210, a fourth middle plate inlet channel 211, a third middle plate inlet 212, a fifth middle plate inlet channel 213, a fourth middle plate outlet 214, a first plate positioning hole 215, and a second middle plate positioning hole 216.
[0066] Among them, the second middle plate outlet 209 is connected to the outlet of the water pump 600, the third middle plate inlet channel 210 is connected to the second middle plate outlet 209, the third middle plate inlet 212 is connected to the fourth middle plate inlet channel 211, and the third middle plate inlet 212 is connected to the fourth main plate inlet channel 112, the fifth middle plate channel is connected to the fourth middle plate outlet 214, and the fourth middle plate outlet 214 is connected to the sixth main plate inlet channel 117.
[0067] In this embodiment, a plurality of first sinks 207 are provided at the bottom of the first middle plate inlet channel 203, and the plurality of first sinks 207 are arranged at intervals along the flow direction of the first middle plate inlet channel 203.
[0068] It is understandable that multiple first settling tanks 207 are arranged sequentially and at intervals along the flow direction of the first middle plate inlet channel 203, so that when the coolant flows in the reservoir, it flows through multiple first settling tanks 207 in sequence, so that high-density impurities in the coolant settle in the first settling tanks 207 to achieve multi-stage sedimentation, thereby filtering out coarse particulate impurities in the coolant. Moreover, the first settling tanks 207 can be integrally formed with the middle plate body 200, so that three-stage filtration can be achieved without the need for additional separate parts.
[0069] Similarly, the bottom of the second middle plate inlet channel 204 is provided with multiple second settling tanks 208, which are arranged sequentially and at intervals along the flow direction of the second middle plate inlet channel 204. Likewise, when the coolant flows in the reservoir, it flows through the multiple second settling tanks 208 sequentially, allowing higher density impurities in the coolant to settle within the second settling tanks 208, achieving multi-stage settling and filtering out coarse particulate impurities in the coolant, thus preventing impurities from circulating with the coolant in the new energy thermal management integration. Furthermore, the second settling tanks 208 can be integrally formed with the middle plate body 200, achieving three-stage filtration without the need for additional components.
[0070] Combination Figures 5-8 The kettle body 300 is provided with a first exhaust chamber 301 in parallel. Figure 7 ) and the second exhaust chamber 302 ( Figure 8Both the first exhaust chamber 301 and the second exhaust chamber 302 have sloping top structures, so that when the coolant flows in the reservoir, the air bubbles in the coolant can be quickly guided to the surface of the reservoir, thereby accelerating the exhaust and preventing the coolant from "trapping air".
[0071] Combination Figures 6-11 The kettle body 300 is provided with a flow channel that is adapted to the upper end of the middle plate 200, and the kettle body 300 is provided with a first kettle outlet 312, a first kettle inlet 313, a first kettle positioning hole 310 and a second kettle positioning hole 311.
[0072] In this embodiment, the top of the kettle body 300 is provided with a first venting structure 303 and a second venting structure 304; the inlet end of the first venting structure 303 is provided with a first water-blocking part 305 at intervals. Figure 10 The second exhaust structure 304 has a second water baffle 306 spaced at its inlet end. Figure 11 ).
[0073] Therefore, when the coolant flows through the first exhaust structure 303, it directly impacts the first water-blocking part 305. The impact of the coolant flow is absorbed by the first water-blocking part 305 and the coolant around it, thereby reducing the impact of the coolant flow and dispersing the large water flow into many small water flows. At the same time, when the coolant flows through the second exhaust structure 304, it directly impacts the second water-blocking part 306. The impact of the coolant flow is absorbed by the second water-blocking part 306 and the coolant around it, thereby reducing the impact of the coolant flow and dispersing the large water flow into many small water flows. This avoids the large water flow directly impacting the liquid surface and generating a lot of noise, further optimizing the NVH performance of the thermal management integrated module.
[0074] Typically, the coolant reservoir body 300 is equipped with water level lines, namely the MIN and MAX lines, and a sight glass 307 is also provided to facilitate observation of the coolant level inside the reservoir. The MAX and MIN lines can be made clearer and more practical by combining changes to the structure of the material in the sight glass 307 and modifications to the polishing process of the plastic mold.
[0075] Combined again Figure 6 The top of the kettle body 300 is provided with a spout 308 and a guide groove 309. The guide groove 309 includes a liquid collection section and a guide section that communicate with each other. The liquid collection section is arranged around the connection between the spout 308 and the top of the kettle body 300, and the guide section is arranged on the side wall of the kettle body 300.
[0076] Understandably, the inclusion of a flow guide 309 at the top of the kettle body 300 allows water droplets to accumulate on the kettle shell when coolant is added or when other factors cause water to fall. These droplets will then flow along the collection section on the kettle body 300 to the flow guide section, and finally be directed to the side of the integrated module to bypass electrical components. This reduces the risk of short circuits in the electrical components below the flow channel plate assembly. Furthermore, the flow guide 309 can be integrally molded with the kettle body 300, eliminating the need for additional complex parts and processing costs, thus improving product reliability and reducing the risk of failure.
[0077] It should be noted that, during the processing of the flow channel plate assembly provided in this embodiment, the main plate body 100 and the middle plate body 200 are first welded together as a whole, and then welded to the kettle body 300 to form a complete flow channel; the pressure cap and the kettle body 300 opening of the flow channel plate assembly are connected by a self-contained thread to form a closed kettle space. Specifically, the first main plate positioning hole 119, the first middle plate positioning hole, and the first kettle positioning hole 310 are paired, and the second main plate positioning hole 120, the second middle plate positioning hole 216, and the second kettle positioning hole 311 are paired.
[0078] In use, the water-to-water heat exchanger 500 is fixedly connected to the flow channel plate assembly with screws to form a closed heat exchange in the space between the two water tanks; the water pump 600 is fixedly connected to the flow channel plate assembly with screws to form the core power source for the operation of the coolant between the flow channels in the thermal management integrated module; the battery heat exchanger assembly 700 is fixedly connected to the flow channel plate assembly with screws to form a system in which the coolant exchanges heat with the refrigerant through the thermal management integrated module when the battery cools down.
[0079] Therefore, during the operation of the new energy thermal management integrated system, the coolant is transported to the water-to-water heat exchanger 500 through the first main board inlet 103, the first main board inlet channel 104, and the first main board outlet 105. After heat exchange, the coolant is transported to the battery heat exchanger assembly 700 through the second main board inlet 106, the second main board inlet channel 107, the second main board outlet 108, and the third main board inlet 109. After heat exchange, the coolant flows to the first middle plate inlet 201 through the third main board inlet 110.
[0080] After the coolant passes through the first mid-plate inlet 201, it is diverted by the flow guiding and splitting structure to the first mid-plate inlet channel 203 and the second mid-plate inlet channel 204, and then converges at the first mid-plate outlet 202. It then enters the fourth main plate inlet 111 and is finally sucked into the inlet of the water pump 600. After passing through the water pump 600, the coolant flows through the second mid-plate outlet 209, through the third mid-plate inlet channel 210, and finally reaches the first coolant outlet 312 to be discharged from the thermal management module.
[0081] Meanwhile, the coolant flows through the first reservoir inlet 313 to the fourth middle plate inlet channel 211 and then into the third middle plate inlet 212. After passing through the fourth main plate inlet channel 112 and the fourth main plate outlet 113, it reaches the water-to-water heat exchanger 500. After heat exchange in the water-to-water heat exchanger 500, the coolant flows through the fifth main plate inlet 114 and the fifth main plate inlet channel 115, and finally exits the thermal management module through the fifth main plate outlet 116.
[0082] When the coolant is added into the reservoir space through the spout 308 of the reservoir body 300, the coolant will flow through the fifth middle plate inlet channel 213, and finally through the fourth middle plate outlet 214, through the sixth main plate inlet channel 117, and then be discharged from the thermal management module through the sixth main plate outlet 118.
[0083] In summary, the thermal management module for hybrid electric vehicles provided in this embodiment includes a main board body 100, a middle board body 200, and a reservoir body 300. The middle board body 200 is provided with a first middle board inlet 201, a first middle board outlet 202, a first middle board inlet channel 203, and a second middle board inlet channel 204. One end of the first middle board inlet channel 203 and the second middle board inlet channel 204 are both connected to the first middle board outlet 202. Meanwhile, the first middle board inlet 201 is adapted with a lateral blocking part 205 and a vertical dividing part 206. The lateral blocking part 205 is located at the front end of the first middle board inlet 201 in the liquid inlet direction. The two cavities separated by the vertical dividing part 206 are respectively connected to the corresponding first middle board inlet channel 203 and the second middle board inlet channel 204, thereby making the first middle board inlet channel 203 and the second middle board inlet channel 204 connected in parallel.
[0084] When the coolant in the new energy thermal management integrated system enters the cavity formed by the middle plate and the kettle body 300 through the first middle plate inlet 201, the transverse baffle 205 causes the coolant to flow towards the side wall of the cavity, thereby reducing the impact force of the coolant entering the kettle and preventing it from directly impacting the top surface of the kettle. The coolant also acts as a buffer within the kettle, significantly reducing noise caused by the water flow. Furthermore, after entering the cavity through the first middle plate inlet 201, the coolant simultaneously flows through the first middle plate inlet channel 203 and the second middle plate inlet channel 204, dispersing the impact force and preventing the coolant from "tumbling" in the kettle. This greatly reduces air bubbles generated during the coolant impact process and improves the venting efficiency of the coolant in the kettle.
[0085] The transverse blocking part 205 and the vertical dividing part 206 are provided at the liquid inlet 201 of the first middle plate. They can be integrally formed with the middle plate body 200 without the need for additional parts. They can simultaneously guide and divert the liquid, and have the characteristics of simple structure and low cost.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
