Description

Technical Field

[0001] This invention belongs to the technical field of intelligent thermal management devices for vehicles, and particularly relates to an intelligent thermal management device that integrates an electric heating element and a compressor for vehicles. Background Technology

[0002] Existing commercial vehicle air conditioning and thermal management systems typically use independent electric heating elements and compressor systems, which have the following problems: 1. When the system starts up, the compressor needs to overcome the high viscosity of the low-temperature refrigerant, resulting in high startup energy consumption and low efficiency; 2. The electric heating element and the compressor operate independently, resulting in insufficient energy utilization. 3. The system has a complex structure, occupies a large space, and has high maintenance costs.

[0003] To address the aforementioned issues, a Chinese patent with publication number CN219988937U proposes a thermal management integrated module and vehicle, "comprising: a compressor and an electric heater; an integrated substrate electrically connected to both the compressor and the electric heater, wherein the integrated substrate is provided with a control module suitable for use by both the compressor and the electric heater." However, the thermal management integrated module provided by this patent has the following shortcomings in practical use: 1. Due to the lack of dynamic predictive control, the heating strategy cannot be adjusted in advance according to changes in ambient temperature. The fixed ratio of electric heating element and compressor power distribution results in low system efficiency and an inability to dynamically adapt to temperature changes. 2. The independent wiring harness design results in high costs; 3. In low-temperature environments, single heating modes (such as compressor or electric heating only) consume high energy and have slow response speed.

[0004] Therefore, it is necessary to invent an intelligent thermal management device that integrates an electric heating element with a compressor for vehicles to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an intelligent thermal management device that integrates an electric heating element with a compressor for vehicles, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent thermal management device integrating an electric heating element and a compressor for a vehicle, comprising a compressor, an integrated controller connected to one side of the compressor, an electric heating device and a housing connected to the side of the integrated controller away from the compressor, and the electric heating device being located in the inner region of the housing; The electric heating device includes a heating resistance wire, a mounting plate, an electric heating tube, and a fixing block.

[0007] Furthermore, the connecting assembly includes a connecting plate, a connecting ring, a hemispherical connecting ball, a spherical protrusion, and a spherical limiting ring.

A slot is provided on the side of the connecting plate near the electric heating tube, and the connecting ring can be inserted into the slot and maintain communication with the air inlet or outlet pipe. There are two spherical protrusions, which are fixedly connected to the inner sides of both ends of the electric heating tube. The two spherical protrusions are designed with openings at the positions directly opposite the axis of the electric heating tube. The connecting ball is rotatably mounted inside the spherical protrusion. The connecting ball is hollow and is fixedly connected to the connecting ring. The connecting ball communicates with the inner side of the electric heating tube and the central area of ​​the connecting ring. The spherical limiting ring is fixedly connected to the edge of the connecting ball away from the connecting ring, and the spherical limiting ring slides against the side of the spherical protrusion away from the connecting ring.

[0008] Furthermore, both the inlet and outlet pipes are L-shaped, and the inlet pipe has a plurality of outlet holes distributed in a ring on its inner surface. A sealing assembly is provided inside the inlet pipe to seal the outlet holes according to the airflow volume. The sealing assembly includes a sealing tube, a telescopic rod, a connecting rod, a return spring, and a flow guiding mechanism. The flow guiding mechanism is connected to the inlet pipe and is used to guide the air flowing out of the outlet holes to the outside of the heating resistance wire. The sealing tube is slidably inserted into the end of the inlet pipe located inside the outer shell, and the sidewall of the sealing tube has a ring of outlet holes. The holes correspond one-to-one with the connecting holes. The top end of the sealing tube protrudes towards the axis of the electric heating tube. The telescopic rod is vertically set at the top axis of the sealing tube, and the top end of the telescopic rod is threadedly connected to the inner wall of the top end of the air inlet pipe. There are multiple connecting rods, which are evenly and fixedly connected between the bottom end of the telescopic rod and the inner wall of the top end of the sealing tube. The return spring is sleeved on the telescopic rod, and the two ends of the return spring are fixedly connected to the telescopic rod near the two ends. The air outlet pipe is provided with an air inlet mechanism that works in conjunction with the sealing assembly.

[0009] Furthermore, the air guiding mechanism includes an air guiding cover, which is fixedly sleeved on one end of the air inlet pipe located inside the outer shell. A notch is provided on the air guiding cover at a position directly opposite to the opening of the connecting plate slot. The air outlet is located in the inner area of ​​the air guiding cover, and the bottom of the air guiding cover is inclined towards the direction of the air guiding cover axis.

[0010] Furthermore, the air intake mechanism includes a connecting pipe, which is connected to the pipe wall of the air outlet pipe located inside the housing. A sealing plate matching the inner diameter of the connecting pipe is hinged to the top inner wall of the connecting pipe. A sealing ring is provided on the side of the sealing plate away from the air intake pipe. The sealing ring is fixedly connected to the inner wall of the connecting pipe and can maintain contact with the sealing plate in a vertical state.

[0011] Furthermore, the top of the fixing block is fixedly connected to an arc-shaped enclosure plate that matches the size of the air guide hood opening. A through hole is provided on the top of the fixing block, and the through hole is located on the side of the arc-shaped enclosure plate close to the air guide hood.

[0012] Furthermore, several heat-conducting plates are horizontally fixedly connected to the inner wall of the outer shell on the side opposite to the electric heating tube. The side of the heat-conducting plate opposite to the electric heating tube has an arc-shaped opening that matches the electric heating tube. When the outer shell is connected to the integrated controller, the heat-conducting plate can be attached to the heating resistance wire on the electric heating tube through the arc-shaped opening.

[0013] Furthermore, the heat-conducting plate is uniformly provided with vent holes, and multiple heat-conducting plates are evenly distributed along the vertical direction.

[0015] Furthermore, a spiral protrusion is fixedly connected inside the electric heating tube, and the length of the spiral protrusion matches the length of the electric heating tube.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention integrates the electric heating device and the compressor through a shared wiring harness and control module, reducing wiring harness redundancy and the number of components. The shared wiring harness saves approximately 30% of wiring costs. Dynamic power allocation: Based on model-predicted load demand, the power supply voltage / current of the compressor and electric heating element is adjusted in real time to avoid overheating or power waste; the integrated controller dynamically adjusts the drive current of the electric heating element and the compressor frequency to ensure optimal power allocation in each mode; multi-mode switching ensures efficient operation even in environments below -20℃; and the heating strategy is adjusted in advance to reduce response delay and improve user experience. 2. By providing a connecting component, when the end of the air inlet pipe or air outlet pipe located inside the housing deforms or tilts, the connecting ring can be pressed, so that the connecting ring can be adjusted according to the direction of deformation or tilt of the air inlet pipe or air outlet pipe, thereby enabling the air inlet pipe and air outlet pipe to be better connected to the electric heating tube, improving the convenience of connecting the air inlet pipe and air outlet pipe to the electric heating tube. 3. By incorporating a sealing component, during the downward movement of the sealing tube by air at a high flow rate, when the connecting hole on the sealing tube coincides with the air outlet on the air inlet pipe, some air can be blown through the air outlet onto the inside of the air guide cover. Subsequently, under the guidance of the air guide cover, the air can be directly blown onto the surface of the heating resistance wire, thereby directly heating this portion of air through the heating resistance wire. This increases the contact area between the heating resistance wire and the air, improving the heating efficiency and heating effect of the heating resistance wire and the electric heating tube.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides, for example Figures 1 to 10 The intelligent thermal management device for vehicles, which integrates an electric heating element with a compressor, includes a compressor 1. An integrated controller 2 is connected to one side of the compressor 1. The integrated controller 2 has a built-in model prediction algorithm that calculates future temperature trends through the prediction model and dynamically adjusts the heating mode of the present invention. An electric heating device and a housing 3 are connected to the side of the integrated controller 2 away from the compressor 1. The electric heating device is located in the inner area of ​​the housing 3. A sealing gasket 26 is provided between the housing 3 and the integrated controller 2. The sealing gasket 26 is made of a high-temperature resistant material to improve the sealing performance of the inner area of ​​the housing 3. The electric heating device includes a heating resistance wire 4, a mounting plate 5, an electric heating tube 6, and a fixing block 7. The mounting plate 5 is detachably mounted on the integrated controller 2. The electric heating tube 6 is vertically arranged on the side of the mounting plate 5 away from the integrated controller 2, and both ends of the electric heating tube 6 are connected to the mounting plate 5 through the fixing block 7. The heating resistance wire 4 is wound around the electric heating tube 6 to heat the air passing through the electric heating tube 6. An air inlet pipe 8 and an air outlet pipe 9 are connected to the outer casing 3. The air inlet pipe 8 and the air outlet pipe 9 can be connected to both ends of the electric heating tube 6, and connecting components are provided at both ends of the electric heating tube 6. The connecting assembly includes a connecting plate 10, a connecting ring 11, a hemispherical connecting ball 12, spherical protrusions 13, and a spherical limiting ring 14. The connecting plate 10 is fixedly connected to one end of the air inlet pipe 8 or the air outlet pipe 9 located inside the housing 3, and the connecting plate 10 communicates with the air inlet pipe 8 or the air outlet pipe 9. A slot is provided on the side of the connecting plate 10 near the electric heating tube 6, and the connecting ring 11 can be inserted into the slot and maintain communication with the air inlet pipe 8 or the air outlet pipe 9. There are two spherical protrusions 13, and the two spherical protrusions 13 are fixedly connected to the electric heating tube 6. The two spherical protrusions 13 on the inner sides of both ends of the heating tube 6 are open at the positions directly opposite the axis of the electric heating tube 6. The connecting ball 12 is rotatably installed inside the spherical protrusions 13. The connecting ball 12 is hollow and is fixedly connected to the connecting ring 11. The connecting ball 12 is connected to the inner side of the electric heating tube 6 and the central area of ​​the connecting ring 11. The spherical limiting ring 14 is fixedly connected to the edge of the connecting ball 12 away from the connecting ring 11, and the spherical limiting ring 14 slides against the side of the spherical protrusion 13 away from the connecting ring 11. Hardware deployment: Compressor 1 and electric heating element 6 are connected to the central integrated controller 2 via a shared wiring harness; temperature sensors are placed in key locations such as the passenger compartment and engine compartment to ensure real-time data transmission; Control Algorithm: The model prediction algorithm combines PID control with neural network prediction. Input variables include ambient temperature and vehicle operating status (such as engine speed and battery charge). The prediction cycle is set to 5 minutes, and the heating mode decision is updated every cycle. In practical use, this invention can dynamically switch heating modes based on an ambient temperature prediction model to achieve power-division heating. The specific process is as follows: 1. The sensors in the vehicle can collect the ambient temperature T and input it into the integrated controller 2; 2. The integrated controller 2 predicts the temperature change within a unit time ΔT in the future based on a preset model (such as historical temperature data, vehicle operating status, etc.); 3. Switch heating modes based on prediction results: If T∈[0, -10℃], activate compressor 1 for separate heating; If T∈[-10, -20℃], start compressor 1 and electric heating tube 6 for coupled heating, according to the predicted power distribution ratio (e.g., compressor 70%, electric heating tube 30%). If T < -20℃, switch to independent heating of electric heating element 6 and reduce the load on compressor 1.

[0021] Therefore, compared with existing thermal management integrated modules, the present invention has the following advantages: Shared wiring harness design: This invention integrates the electric heating device and the compressor 1 through a shared wiring harness and control module, reducing wiring harness redundancy and the number of components. The shared wiring harness saves about 30% of wiring costs. Dynamic power allocation: Based on the load demand predicted by the model, the power supply voltage / current of compressor 1 and electric heating element 6 is adjusted in real time to avoid overheating or power waste; the drive current of electric heating element 6 and the frequency of compressor 1 are dynamically adjusted by integrated controller 2 to ensure optimal power allocation in each mode; An intermittent heating strategy is adopted at extremely low temperatures to avoid continuous high load on the electric heating element 6; Fault redundancy mechanism: When compressor 1 or electric heating element 6 fails, the system automatically switches to standby mode and alarms.

[0022] Energy efficiency improvement: By adopting a zoned heating strategy, overall energy consumption is reduced, achieving 15-20% energy savings compared to traditional systems; Low temperature adaptability: Multi-mode switching ensures efficient operation even in environments below -20℃; Intelligent prediction: Adjust heating strategies in advance to reduce response delay and improve user experience; Experimental verification: Compared with the traditional independent system at -15℃, the energy consumption of this system is reduced by 18% and the heating speed is increased by 25%; under the extreme low temperature test (-25℃), the power requirement of electric heating tube 6 is reduced by 40% compared with the traditional solution.

[0023] Furthermore, when connecting the outer casing 3 to the integrated controller 2, as the outer casing 3 is gradually fastened onto the integrated controller 2, the connecting rings 11 at both ends of the electric heating tube 6 can be inserted into the slots of the connecting plates 10 on the inlet pipe 8 and the outlet pipe 9, respectively, thereby realizing the connection operation between the electric heating tube 6 and the inlet pipe 8 and the outlet pipe 9. However, during long-term use of this invention, due to the high internal temperature of the outer casing 3 and the vibration generated by the compressor 1 during operation, the connection points between the inlet pipe 8 and the outlet pipe 9 and the electric heating tube 6 may deform or tilt under the action of high temperature and vibration. Therefore, after disassembling the outer casing 3 for inspection, it is difficult for the end of the inlet pipe 8 and the outlet pipe 9 located inside the outer casing 3 to overlap with the end of the electric heating tube 6. When the two pipes are newly connected, the connecting components are provided. When the end of the air inlet pipe 8 or the air outlet pipe 9 inside the housing 3 is deformed or tilted, the connecting ring 11 can be pressed, causing the connecting ball 12 to rotate within the spherical protrusion 13. At the same time, the spherical limiting ring 14 can slide along the side of the spherical protrusion 13 away from the connecting ring 11. As the connecting ball 12 rotates, the connecting ring 11 can also move and deflect with the connecting ball 12, so that the connecting ring 11 can be adjusted according to the direction of deformation or tilt of the air inlet pipe 8 or the air outlet pipe 9. This allows the air inlet pipe 8 and the air outlet pipe 9 to be better connected to the electric heating tube 6, improving the convenience of connecting the air inlet pipe 8 and the air outlet pipe 9 to the electric heating tube 6.

[0024] like Figures 2 to 7 As shown, both the intake pipe 8 and the exhaust pipe 9 are L-shaped, and the intake pipe 8 has several exhaust holes 15 arranged in a ring on the inner surface of the outer casing 3. A sealing assembly is provided inside the intake pipe 8 to seal the exhaust holes 15 according to the airflow volume. The sealing assembly includes a sealing tube 16, a telescopic rod 17, a connecting rod 18, a return spring 19, and a flow guiding mechanism. The flow guiding mechanism is connected to the intake pipe 8 and is used to guide the air flowing out of the exhaust holes 15 to the outside of the heating resistance wire 4. The sealing tube 16 is slidably inserted into one end of the intake pipe 8 located inside the outer casing 3, and the side wall of the sealing tube 16 has several exhaust holes arranged in a ring. The air vent 15 has a corresponding connecting hole. The top of the sealing tube 16 protrudes towards the axis of the electric heating tube 6. The telescopic rod 17 is vertically set at the top axis of the sealing tube 16, and the top of the telescopic rod 17 is threadedly connected to the inner wall of the top of the air inlet pipe 8. There are multiple connecting rods 18, which are evenly fixedly connected between the bottom of the telescopic rod 17 and the inner wall of the top of the sealing tube 16. The return spring 19 is sleeved on the telescopic rod 17, and the two ends of the return spring 19 are fixedly connected to the telescopic rod 17 near the two ends. The air outlet pipe 9 is provided with an air inlet mechanism that works with the sealing assembly. The air guiding mechanism includes an air guiding cover 20, which is fixedly sleeved on one end of the air inlet pipe 8 located inside the outer shell 3. A notch is provided on the air guiding cover 20 at a position directly opposite to the slot opening of the connecting plate 10. The air outlet 15 is located in the inner area of ​​the air guiding cover 20, and the bottom of the air guiding cover 20 is inclined towards the axis of the air guiding cover 20. The air intake mechanism includes a connecting pipe 21, which is connected to the pipe wall of the air outlet pipe 9 located inside the outer casing 3. A sealing plate 22 matching the inner diameter of the connecting pipe 21 is hinged to the top inner wall of the connecting pipe 21. A sealing ring 23 is provided on the side of the sealing plate 22 away from the air intake pipe 8. The sealing ring 23 is fixedly connected to the inner wall of the connecting pipe 21, and the sealing ring 23 can keep in contact with the sealing plate 22 in the vertical state. When T∈[-10, -20℃], the electric heating tube 6 is in a cooperative working state. At this time, the air flow rate into the electric heating tube 6 through the air inlet pipe 8 is low, while the sealing tube 16 can keep the connecting hole on the sealing tube 16 and the air outlet 15 on the air inlet pipe 8 staggered under the pulling force of the return spring 19. At this time, the air can completely pass through the inside of the electric heating tube 6 and be heated by the heating resistance wire 4. Then the heated air can be sent into the carriage through the air outlet pipe 9, thereby realizing the heating operation of the carriage. When T < -20℃, the electric heating element 6 is in full working condition. At this time, the air velocity entering the electric heating element 6 through the air inlet pipe 8 is also relatively high. When the high-velocity air blows onto the protruding part at the top of the sealing tube 16, the sealing tube 16 can move downward under the action of the airflow. During this process, the telescopic rod 17 and the return spring 19 can be gradually stretched. As the sealing tube 16 continues to move downward, when the connecting hole on the sealing tube 16 coincides with the air outlet 15 on the air inlet pipe 8, some air can be blown into the inside of the air guide cover 20 through the air outlet 15. Subsequently, under the guidance of the air guide shroud 20, the air is blown directly onto the surface of the heating resistance wire 4, thereby directly heating this part of the air through the heating resistance wire 4, thereby increasing the contact area between the heating resistance wire 4 and the air, and improving the heating efficiency and heating effect of the heating resistance wire 4 and the electric heating tube 6 on the air. Then, the heated air can push open the sealing plate 22 in the connecting pipe 21 and enter the air outlet pipe 9. Finally, the heated air can be sent into the carriage through the air outlet pipe 9, thereby realizing the heating operation of the carriage.

[0025] like Figure 2 and Figure 8 As shown, the top of the fixing block 7 is fixedly connected to an arc-shaped enclosure 24 that matches the size of the notch in the air guide hood 20. The top of the fixing block 7 has a through hole, and the through hole is located on the side of the arc-shaped enclosure 24 close to the air guide hood 20. Several heat-conducting plates 25 are horizontally fixedly connected to the inner wall of the outer shell 3 on the side opposite to the electric heating tube 6. The side of the heat-conducting plate 25 opposite to the electric heating tube 6 has an arc-shaped opening that matches the electric heating tube 6. When the outer shell 3 is connected to the integrated controller 2, the heat-conducting plate 25 can be attached to the heating resistance wire 4 on the electric heating tube 6 through the arc-shaped opening. Ventilation holes are evenly opened on the heat-conducting plate 25, and the multiple heat-conducting plates 25 are evenly distributed in the vertical direction. As the outer shell 3 and the integrated controller 2 gradually come together, the arc-shaped enclosure 24 can close the gap in the air guide shroud 20, so that the air guide shroud 20 forms a complete ring, thereby ensuring that the air flowing out from the inside of the air guide shroud 20 can be blown evenly on the outside of the heating resistance wire 4, thereby improving the uniformity of the heating resistance wire 4 when it directly heats the air. The through hole on the fixing block 7 allows the air to pass through the through hole and contact the surface of the heating resistance wire, preventing the air from being blocked by the fixing block 7. Furthermore, by providing a heat-conducting plate 25, after the outer casing 3 is connected to the integrated controller 2, the heat-conducting plate 25 can adhere to the surface of the heating resistance wire 4, thereby uniformly transferring the heat generated by the heating resistance wire 4 to the heat-conducting plate 25. Thus, when air flows out through the air outlet 15 to the outer area of ​​the electric heating tube 6, the heat-conducting plate 25 can increase the contact area between the heating resistance wire 4 and the air, thereby improving the direct heating effect of the heating resistance wire 4 on the air.

[0026] like Figure 9 A spiral protrusion 27 is fixedly connected inside the electric heating tube 6, and the length of the spiral protrusion 27 matches the length of the electric heating tube 6. With the spiral protrusion 27 provided, when air enters the electric heating tube 6 through the air inlet pipe 8, the air can flow spirally towards the air outlet pipe 9 along the inner wall of the electric heating tube 6 under the guidance of the spiral protrusion 27, so that the air can be better heated by the inner wall of the electric heating tube 6, thereby improving the heating effect of the electric heating tube 6. In addition, the presence of the spiral protrusion 27 allows the air to stay in the electric heating tube 6 for a longer time, thereby ensuring that the air can be fully heated and thus ensuring that the heated air can better provide heat to the carriage.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
