[0002] With the rapid development of the new energy vehicle industry, the demand for integrated, miniaturized, and precisely temperature-controlled vehicle heating systems is increasing. Currently, most vehicle heating systems use a combination of compressor and membrane heating device. The membrane heating device heats the circulating liquid, which is then supplied to the driver's cab via heat dissipation fins.

[0003] The heating film transmits current to the circuit board through electrodes to generate heat. However, the electrode assemblies in the existing technology still have the following drawbacks when in use: 1. The electrode assembly contains multiple sets of electrodes, namely high-pressure end and low-pressure end. The low-pressure end is mainly used to obtain water temperature and membrane temperature data. This method of using multiple electrodes results in many solder joints, which may lead to faults such as poor soldering and desoldering, and data acquisition may drift. 2. There is no fixed position between the plastic coating of the electrode and the cylindrical membrane, and there will be a gap between them. When welding the electrode, the plastic coating may shift, affecting the welding quality of the electrode.

[0004] There are currently no effective solutions to the problems in the relevant technologies.

[0020] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figure 1 According to an embodiment of the present invention, an electrode assembly integrated in a compressor membrane heating device includes a compressor 1. A membrane heating assembly housing 2 is bolted to the compressor 1. The compressor 1 provides an installation base. The membrane heating assembly and control module are integrated to achieve an integrated design of the compressor 1 and the heating device, reducing space occupation and improving system integration. A circular tube membrane assembly 3 is installed inside the membrane heating assembly housing 2. The circular tube membrane assembly 3 includes two sets of parallel-arranged circular tube heating membranes. The circular tube membrane assembly 3 is the core heating component. Rapid heating is achieved through the two sets of circular tube heating membranes. The circular tube structure increases the heating area and improves thermal efficiency. An electrode plastic coating 6 is installed between the two sets of circular tube heating membranes. The electrode plastic coating 6 realizes the conduction of current. Please see Figure 1 , Figure 3 and Figure 4The electrode coating component 6 includes an upper coating base 61, a lower coating base 64, and an electrode 66. The upper coating base 61 has a first mounting hole 62, and the lower coating base 64 has a second mounting hole 65. The upper and lower coating bases 61 and 64 are connected and fixed by bolts passing through the first and second mounting holes 62 and 65. The split-type coating structure design minimizes electrode assembly tolerances, ensuring precise alignment with the circular heating film. The upper coating base 61 has mounting holes on both sides. There is an arc-shaped structure A63, and arc-shaped structures B67 matching the arc-shaped structure A63 are also provided on both sides of the lower plastic-coated base 64. The arc-shaped structures A63 and B67 match the curvature of the outer surface of the circular heating film, which can achieve accurate positioning when installing the entire electrode plastic-coated part 6. The electrode 66 is Y-shaped in general, with its main section running through the entire lower plastic-coated base 64 along the vertical axis, and its two left and right branches running through the side walls of the upper plastic-coated base 61. The upper plastic-coated base 61 and The lower plastic-coated base 64 is made of PPS-GF65 material, where PPS represents polyphenylene sulfide, GF represents glass fiber, and 65 represents that the glass fiber accounts for 65% of the material by mass. Polyphenylene sulfide (PPS) has high temperature resistance and chemical corrosion resistance. The mechanical strength is greatly improved after 65% glass fiber reinforcement, which meets the requirements of the high temperature and high pressure environment inside the compressor 1. The electrode 66 is a high-voltage terminal. The electrode 66 is made of H65 copper with a tin-plated surface and a tin plating thickness of 10μm. H65 copper has excellent conductivity, and the tin plating layer prevents oxidation. The 10μm thickness balances cost and corrosion resistance, ensuring long-term stable conductivity of the high-voltage terminal. The assembly sequence of the electrode plastic-coated part 6 is as follows: first, the upper plastic-coated base 61 and the lower plastic-coated base 64 are fastened with self-tapping screws. During this process, since the arc-shaped piece 63 is close to the outer surface of the circular tube heating film, it can play a good positioning effect on the upper plastic-coated base 61. Then, the two ends of the electrode 66 are welded to the two circular tube heating films respectively.

[0021] Please see Figure 1 The compressor 1 is equipped with a two-in-one control main board 4, which integrates the dual functions of compressor operation control and membrane heating device power adjustment.

[0022] Please see Figure 1 and Figure 2 The membrane heating assembly housing 2 has an adapter circuit board 5 installed inside. The adapter circuit board 5 is located between the circular tube membrane assembly 3 and the two-in-one control main board 4. The adapter circuit board 5 serves as a relay node for control signals and heating power. On the one hand, it receives commands from the control main board, and on the other hand, it distributes high-voltage current to each group of electrodes. At the same time, it integrates temperature signal conditioning circuits to improve system integration.

[0023] Please see Figure 1 and Figure 2The two-in-one control motherboard 4 and the adapter circuit board 5 are connected by a connector 7. The connector 7 includes two sets of sockets installed on the adapter circuit board 5 and two sets of plugs installed on the two-in-one control motherboard 4. The plugs and sockets are connected by plugging in, and a male and female plug structure is used to achieve quick assembly.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The bottom end of electrode 66 is connected to the adapter circuit board 5. The top ends of the two branches of electrode 66 are welded to two sets of circular heating films respectively. Electrode 66 is in direct contact with the circular heating film, thereby conducting current to the heating film and enabling the film to heat up.

[0025] Please see Figure 2 Two sets of temperature acquisition sensors 8 are installed on the adapter circuit board 5. The signal acquisition ends of the temperature acquisition sensors 8 extend into the interior of the two sets of circular heating films respectively. The temperature acquisition sensors 8 monitor the temperature of the two sets of circular heating films in real time and feed it back to the two-in-one control motherboard 4.

[0026] The working principle of an electrode assembly integrated in a compressor membrane heating device is as follows: The two-in-one control main board 4 outputs a heating power signal according to the set operating conditions, which is transmitted to the adapter circuit board 5 via the connector 7. The adapter circuit board 5 distributes the high-voltage current through the main section of the Y-shaped electrode 66 to two branches, and finally delivers it to the conductive layer of the two sets of circular tube heating films, so that the heating film layer generates heat. The temperature acquisition sensor 8 monitors the temperature of the center of the coolant in the circular tube heating film in real time, converts the analog signal into a digital quantity, and feeds it back to the two-in-one control main board 4. The two-in-one control main board 4 dynamically adjusts the output power according to the deviation between the set temperature and the actual temperature. If the temperature is too low, the current is increased; if the temperature is too high, the heating is cut off, thus achieving precise temperature control. The electrode plastic coating 6 provides mechanical support through the rigid connection between the upper plastic coating base 61 and the lower plastic coating base 64. The arc structure A63 and the arc structure B67 ensure the precise alignment of the circular tube heating film and the electrode 66. The insulation performance of the PPS-GF65 material prevents high-voltage leakage and at the same time blocks the heating component from transferring too much heat to the compressor, ensuring that each component works in the optimal temperature range.

[0028] 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.
