Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle technology, specifically, it relates to a membrane electric heating device integrated on a new energy vehicle compressor. Background Technology

[0002] With the rapid development of the new energy vehicle industry, in-vehicle heating in winter has become a core requirement affecting user experience. Traditional fuel vehicles can use the waste heat from the engine to heat the cabin, while new energy vehicles (especially pure electric vehicles) have no engine waste heat to utilize and must rely on electric heating devices to achieve in-vehicle heating. Membrane electric heating devices have become the core choice due to their unique advantages, such as fast heating speed, high safety, and the ability to stably provide heating heat to the vehicle interior.

[0003] In the air conditioning systems of new energy vehicles, the compressor mainly undertakes the refrigerant compression function of the refrigeration cycle or heat pump system. However, in existing technologies, the compressor and membrane electric heating device are generally designed as separate units: each is independently designed and installed in the vehicle chassis or engine compartment, requiring dedicated mounting brackets, fluid delivery pipelines, and electrical control circuits, operating independently to achieve refrigeration / heat pump and heating functions. This separate design also presents the following technical problems in practical use: 1. Large space occupation: Both require independent installation space and pipeline connection, which increases the complexity of the overall vehicle layout, especially in small new energy vehicles, which can easily lead to tight cabin space; 2. Low system integration: Additional design of fixed brackets, electrical wiring harnesses and fluid pipelines is required, which increases the number of parts and assembly processes, thereby increasing production costs and failure rate.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0005] Therefore, in order to solve the above problems, this utility model provides a membrane electric heating device integrated into the compressor of a new energy vehicle. Utility Model Content

[0006] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a membrane electric heating device integrated into the compressor of a new energy vehicle.

[0007] The objective of this utility model can be achieved through the following technical solutions: A membrane electric heating device integrated into a compressor of a new energy vehicle includes a compressor, and a heating component is mounted on one side of the compressor; The heating assembly includes a housing that is bolted to the compressor housing. Inside the housing are a first circular tube membrane heating mechanism and a second circular tube membrane heating mechanism. The first and second circular tube membrane heating mechanisms include a metal circular tube and a heating film covering its outer surface. Coolant flows inside the circular tube. The first and second circular tube membrane heating mechanisms are arranged side by side and inclined inside the housing. A partition is installed between the housing and the compressor. The shell is also equipped with an electrode plastic-coated component, which is disposed between the first circular tube film heating mechanism and the second circular tube film heating mechanism. A circuit board is also installed inside the housing.

[0008] Furthermore, a mounting hole is provided at one end of the housing, and a mounting plate is installed at the mounting hole by bolts. A water outlet and a water inlet are installed on the mounting plate.

[0009] Furthermore, one end of the water outlet is connected to the first circular membrane heating mechanism, and one end of the water inlet is connected to the second circular membrane heating mechanism.

[0010] Furthermore, a connecting sleeve is provided inside the housing, and the connecting sleeve is welded to the other end of the first circular tube membrane heating mechanism and the second circular tube membrane heating mechanism.

[0011] Furthermore, one end of the electrode on the electrode-coated part is connected to the circuit board, and the other end of the electrode on the electrode-coated part is connected to the first circular tube film heating mechanism and the second circular tube film heating mechanism.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the membrane heating component is directly integrated into the compressor housing, and the compressor is used as the installation carrier of the heating component. This eliminates the need for independent mounting brackets, redundant pipelines and lines for the membrane heating component, reduces the number of parts, simplifies the overall structure, and reduces production costs and assembly process complexity. At the same time, the integrated design eliminates the need to check the two sets of devices separately during later maintenance, significantly improving maintenance efficiency.

[0013] 2. In this utility model, the heating component and the compressor share the installation space, eliminating the need to reserve an independent installation area for the membrane heating component. This effectively frees up space in the chassis / engine compartment of new energy vehicles, better adapts to the needs of vehicle miniaturization and lightweighting, and improves the flexibility of vehicle space layout.

[0014] 3. In this utility model, the heating film is directly wrapped around the outer surface of the high thermal conductivity metal round tube, and the heat can be quickly conducted to the coolant inside the tube. The heat transfer path is short and the heat loss is small. In addition, the first and second round tube film heating mechanisms are arranged in series to achieve step-by-step full heating of the coolant. At the same time, the transport path of the heated coolant is shortened, the heat loss of the pipeline is reduced, the heating efficiency inside the vehicle is greatly improved, and the energy consumption is reduced.

[0018] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments: Please see Figure 1 According to an embodiment of the present invention, a membrane electric heating device integrated on a new energy vehicle compressor includes a compressor 1. The compressor 1 serves as a basic component, and its integrated design provides an installation carrier for the subsequent heating component 2, simplifying the overall structure. The heating component 2 is mounted on one side of the compressor 1, and the whole device integrates membrane heating function to heat the coolant. Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The heating assembly 2 includes a housing 21 bolted to the outer casing of the compressor 1. The housing 21 contains an internal cavity forming an independent heating chamber. A first circular tube film heating mechanism 25 and a second circular tube film heating mechanism 26 are installed inside the housing 21. Each mechanism includes a metal circular tube and a heating film covering its outer surface. Coolant flows through the circular tube, which is made of a metal with excellent thermal conductivity (such as stainless steel). This serves as a coolant channel and efficiently transfers heat from the heating film to the coolant inside the tube, ensuring heating efficiency. The first circular tube film heating mechanism 25... The first and second circular tube membrane heating mechanisms 25 and 26 serve as the core components of membrane heating. They contact the coolant through the circular tube membrane structure, utilizing the material's properties to achieve heating. The first and second circular tube membrane heating mechanisms 25 and 26 are arranged side-by-side, but inclined within the housing 21. This effectively increases the heating power while maintaining a relatively small compressor-in-one design. The axially inclined arrangement allows the heating membrane to be positioned as far away from the circuit board 4 as possible, reducing heat radiation to the PCBA board. Because the first and second circular tube membrane heating mechanisms 25 and 26 are inclined, corresponding positions on the housing 21 are also machined into an inclined shape (e.g., ...). Figure 2 As shown), the housing 21 is better molded, and the compressor has a more beautiful and harmonious appearance. A partition 22 is installed between the housing 21 and the compressor 1. The partition 22 can prevent the heat of the heating component 2 from being transferred to non-target areas of the compressor 1, so as to avoid affecting the normal operating temperature of the compressor 1. At the same time, it can also prevent oil and impurities inside the compressor 1 from entering the housing 21, thus protecting the internal electrical components and heating mechanism. Please see Figure 3 and Figure 4 Inside the housing 21, an electrode-coated component 3 is also installed. The electrode-coated component 3 is positioned between the first circular tube membrane heating mechanism 25 and the second circular tube membrane heating mechanism 26. The electrode-coated component 3 transmits current and insulates and protects the electrodes. Inside the housing 21, a circuit board 4 is also installed. One end of the electrode on the electrode-coated component 3 is connected to the circuit board 4, and the other end of the electrode on the electrode-coated component 3 is connected to the first circular tube membrane heating mechanism 25 and the second circular tube membrane heating mechanism 26. The circuit board 4 is mounted on the partition 22 and is located below the electrode-coated component 3. It integrates a temperature detection module and a power control circuit. The circuit board 4 is the "control center" of the heating component, responsible for power supply management, heating power adjustment and safety protection. The circuit board 4 transmits a stable current to the heating film on the first circular tube membrane heating mechanism 25 and the second circular tube membrane heating mechanism 26 through the motor of the electrode-coated component 3, thereby achieving the heating effect.

[0019] Please see Figure 3The housing 21 has a mounting hole 23 at one end, and a mounting plate 24 is installed at the mounting hole 23 by bolts. The mounting plate 24 has an outlet 27 and an inlet 28. One end of the outlet 27 is connected to the first circular tube membrane heating mechanism 25, and one end of the inlet 28 is connected to the second circular tube membrane heating mechanism 26. The outlet 27 and the inlet 28 are connected to the external pipeline by threads or quick-connect structure to ensure unidirectional flow of coolant. The liquid enters the second circular tube membrane heating mechanism 26 from the inlet 28, flows into the first circular tube membrane heating mechanism 25, is heated, and then flows out from the outlet 27. At the same time, the sealing performance is ensured to prevent coolant leakage.

[0020] Please see Figure 3 and Figure 4 Inside the housing 21, a connecting sleeve 29 is also provided. The connecting sleeve 29 is welded to the other end of the first circular tube membrane heating mechanism 25 and the second circular tube membrane heating mechanism 26. The connecting sleeve 29 is located at the outlet end of the first circular tube membrane heating mechanism 25 and the inlet end of the second circular tube membrane heating mechanism 26. The cavity inside the connecting sleeve 29 can provide space for the flow of coolant, so that the coolant flowing out from the second circular tube membrane heating mechanism 26 can enter the first circular tube membrane heating mechanism 25, while also preventing the leakage of coolant inside the tube.

[0021] The working principle of a membrane electric heating device integrated into a new energy vehicle compressor is as follows: An external power source supplies stable electrical energy to the circuit board 4 of the heating component 2. The circuit board 4 accurately transmits the current to the heating films of the first circular tube membrane heating mechanism 25 and the second circular tube membrane heating mechanism 26 through the electrodes of the electrode plastic-coated part 3. After the heating film is energized, it quickly generates heat. Because the heating film is tightly attached to the metal circular tube, the heat is directly and efficiently conducted to the coolant flowing inside the tube. The heat transfer path is short and the heat loss is small, which greatly improves the heating efficiency. The coolant to be heated enters the inlet 28 on the mounting plate 24 through the external circulation pipeline. It flows into the metal circular tube of the second circular tube membrane heating mechanism 26 and completes the initial heating. Subsequently, the coolant passes through the metal circular tube welded to the ends of the two heating mechanisms. The connecting sleeve 29 flows into the metal tube of the first circular tube membrane heating mechanism 25 for deep heating. The hot liquid, after being deeply heated by the first circular tube membrane heating mechanism 25, flows out of the heating component 2 through the outlet 27 on the mounting plate 24, and is then transported to the heat dissipation fins in the driver's cab through the external circulation pipeline. At this time, the vehicle fan starts and blows the heat of the hot liquid on the heat dissipation fins into the driver's cab, ultimately achieving vehicle heating. It is worth noting that the first circular tube membrane heating mechanism 25 and the second circular tube membrane heating mechanism 26 are arranged at an angle in the housing 21. Within a limited volume, the heating power is increased. This facilitates the discharge of air from the chamber during liquid filling, avoiding air resistance affecting circulation, and also keeps the heating mechanism away from the circuit board 4 below, reducing the interference of heat radiation on the electronic components of the circuit board.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
