In addition, the existing thermal management module cannot be easily disassembled and stably heated.

[0003] The Chinese invention patent with application number CN202410603038.1 records and discloses an electric compressor with a side-mounted integrated heating module. This solution integrates the heating module at the bottom of the control unit to reduce the difficulty of installation. At the same time, a heating module is set at the bottom of the control unit near the compressor air inlet, which can heat the fluid medium more quickly, especially the refrigerant entering the compressor, thereby increasing the heating speed of the compressor.

[0004] However, the above solution still has the following problems:

[0006] The fluid medium stays in the heating module for a short time and cannot be fully heated. The fluid medium is discharged at a low temperature, and the heating speed of the designated area (battery and interior of the vehicle) is slow.

[0007] Therefore, a new solution needs to be proposed to solve the problem of poor heating efficiency of batteries and vehicle compartments under low temperature conditions. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a spoiler structure, a heating component, and an electric compressor integrated system, aiming to improve the heating efficiency of the compressor at low temperatures.

[0015] The utility model is further configured such that the length direction of the flow-disturbing structure forms an angle with the flow direction of the fluid medium, the side wall of the fixed plate is provided with a liquid inlet and a liquid outlet, and the distances between the first blocking portion, the guide portion, the second blocking portion and the liquid inlet gradually increase.

[0016] The utility model is further configured as follows: the guide channel is C-shaped.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0033] like Figure 1 As shown, the electric compressor integrated system includes a heating component and a compressor body 10, which are powered by an on-board power supply to ensure stable and efficient energy supply. The heating component is installed on the side of the compressor body 10 close to the air inlet. When the heating component is installed on the compressor body 10, the heating module is located on the side of the heating component away from the compressor. A control unit is installed on the side of the compressor body 10, and a control chip is provided in the control unit. The heating module and the compressor body 10 are electrically connected to the control unit. The control chip of the control unit controls the compressor body 10 and the heating module, and the drive motor and the heating module of the compressor body 10 are controlled by the same control chip, and can be controlled by the on-board power supply. The high-voltage output end of the power source uniformly supplies power to the drive motor and heating module of the compressor body 10. Compared with the conventional technology of separately setting up the heating component, it can reduce at least one high-voltage plug-in and one low-voltage plug-in, significantly reducing the hardware cost. Centralized control is performed through a control chip, which reduces the transmission time of the control signal, thereby speeding up the response speed of controlling the compressor body 10 and / or the heating module, thereby improving the starting efficiency and heating effect of the compressor body 10, further realizing the compact layout and efficient thermal management of the electric compressor integrated system, providing good temperature control for the compressor body 10, and ensuring the stable operation and long-term reliability of the electric compressor integrated system.

[0034] like Figures 1-4As shown, the heater assembly includes an aluminum base plate 2 and an aluminum fixed plate 3 with an opening on the upper side. A heating chamber is formed between the base plate 2 and the fixed plate 3. The side wall of the fixed plate 3 is provided with a liquid inlet 41 and a liquid outlet 42 for conveying a fluid medium. The fluid medium is a liquid that can flow stably. The heating module and the heat exchange module are arranged in the heating chamber. The heat exchange module is located between the heating module and the fixed plate 3. The heating module includes an aluminum support plate 4 arranged in the heating chamber and a plate-shaped heating body fixed on one side surface of the support plate 4. The heating body is used to heat the fluid medium or the heating module. The heating body can be a thick film heater, a thin film heater or a PTC heater. In at least one embodiment, a Water is used as the fluid medium, and the heating element is configured as a PTC heater. Compared to other heaters, this heater has the advantages of rapid heating, automatic temperature control in the event of a blower failure, and a long service life. This improves operational stability and reduces the risk of failure. The plate-shaped heating element can heat the fluid medium over a large area, improving heating efficiency. The heated fluid medium is then transported to the area to be heated, including the battery and the vehicle compartment. Because the heating module is located near the compressor's air inlet, the heating element can heat the heating module by radiating heat, thereby increasing the compressor body's 10 exhaust temperature. This improves the compressor body's 10 heating response speed.

[0035] like Figure 2 and Figure 4 As shown, the heat exchange module includes several long plate-shaped aluminum partitions 5, and the side of the support plate 4 close to the fixed plate 3 is divided by the partition 5 to form a plurality of C-shaped guide channels 6. The guide channels 6 extend the flow path of the fluid medium and the setting of multiple guide channels 6 optimizes the flow path and heating process of the fluid medium, so that the fluid medium can be fully heated during the circulation in the guide channels 6. The upper end of the partition 5 is provided with several air guide grooves 8 connecting adjacent guide channels 6. The C-shaped structure of the guide channel 6 and the air guide grooves 8 opened at the upper end of the partition 5 work together, which is not only conducive to the smooth flow of the fluid, but also can guide the air entering the guide channel 6 through the air guide grooves 8, and quickly discharge the gas entering the heating component, thereby reducing or avoiding dry burning caused by bubble aggregation.

[0036] like Figure 5-Figure 7As shown, the guide channel 6 is provided with a flow disturbance structure 1 that guides the fluid medium of the bottom layer to the upper layer. The inlet and outlet ends of the guide channel 6 are both provided with a flow disturbance structure 1. The number of the flow disturbance structures 1 can be set according to actual needs. The flow disturbance structure 1 is in a twisted streamline shape and is forged into an integral part in the guide channel by forging. The flow disturbance structure 1 includes a first blocking portion 11, a guide portion 13 and a second blocking portion 12. The length direction of the flow disturbance structure 1 forms an angle with the flow direction of the fluid medium. The distances between the first blocking portion 11, the guide portion 13 and the second blocking portion 12 and the liquid inlet 41 gradually increase. After the fluid medium flows into the guide channel 6, the first blocking portion 11 blocks the fluid medium of the bottom layer and guides the fluid medium to the guide portion 13. The guide portion 13 guides the fluid medium from the first blocking portion 11 to the second blocking portion 12. The second blocking portion 12 A drainage groove 121 is provided on the top, and a gap is left between the upper end surface of the second blocking part 12 and the heating module. The fluid medium guided to the second blocking part 12 is discharged through the gap and the drainage groove 121, which optimizes the flow path of the fluid medium and promotes the heat exchange efficiency. The disturbing structure 1 causes the liquid fluid medium to fluctuate in the guide channel 6. The first blocking part 11 blocks the fluid and the guide part 13 guides the fluid medium in the bottom layer to the upper layer closer to the heating module through trajectory guidance, ensuring that the fluid medium can evenly contact the heating module, thereby forming turbulence in the guide channel 6, realizing heating of the bottom fluid medium, reducing the formation of different heat stratification of the fluid medium, thereby effectively improving the uniformity of heating the fluid medium, improving the temperature stability of the output fluid medium, and facilitating the control of the temperature of the fluid medium.

[0037] like Figure 1 、 Figure 2 and Figure 5As shown, the liquid inlet 41 and the liquid outlet 42 are located on the same side of the fixed plate 3, and the two ends of the plurality of guide channels 6 are respectively connected to the liquid inlet 41 and the liquid outlet 42. A first confluence groove 91 is formed between the guide channel 6 and the liquid inlet 41, and the first confluence groove 91 is connected to the inlet end of the plurality of guide channels 6. A second confluence groove 92 is formed between the guide channel 6 and the liquid outlet 42, and the second confluence groove 92 is connected to the outlet end of the plurality of guide channels 6. By being connected with multiple guide channels 6, each part of the fluid medium can be evenly heated when flowing through the heating module, thereby avoiding local overheating or insufficient heating. After the fluid medium is input into the liquid inlet 41, the fluid medium gathers and preheats in the first confluence groove 91 and then enters the guide channel 6, so that heat can be absorbed more efficiently in the guide channel 6. The heated fluid medium is discharged into the second confluence groove 92 and discharged from the liquid outlet 42. The second confluence groove 92 collects and evenly mixes the heated fluid medium, which helps to achieve precise control of the temperature of the fluid medium discharged from the liquid outlet 42. The heating body not only heats the fluid medium, but also heats the heating module and the compressor body 10 through heat radiation, so that the lubricating oil in the compressor body 10 can quickly release the viscous state, reducing the time required for starting the compressor body 10, thereby improving the efficiency of vehicle air conditioning heating. The heated fluid medium can be transported to the condenser through a circulating pump to heat the designated area. It can be understood that the fluid medium can be transported to a warm air device including a condenser or directly connected to the air conditioning system in the car.

[0038] like Figure 1-Figure 7 As shown, through the arrangement of the C-shaped guide channel 6 and the spoiler structure 1, the fluid medium at the bottom layer can also contact the heating module, thereby improving the heating efficiency of the fluid medium. The heating component not only improves the heating efficiency and uniformity of the fluid, but also ensures the long-term stable operation of the equipment and reduces maintenance costs. Through the integrated design and optimization of the heater component with the electric compressor integrated system, the compressor body 10 and the heater component can work together during the heating process. The total volume after integration is small. Through the efficient heating, heat exchange and control system, the heating efficiency and performance stability of the automobile air conditioner are improved, the battery and the car compartment are heated quickly and evenly, the heating efficiency is improved, the stability is enhanced, the uniformity of the heat transfer medium is improved, the heating efficiency of the battery and the car compartment under low temperature conditions is improved, the maintenance cost is reduced, and energy consumption is saved.
