[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only a part of the embodiments disclosed in this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Various non-limiting embodiments of this utility model are described in detail below. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0033] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0034] Please see Figure 1-7 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: A compact air conditioning system includes a base plate 1. A condensing module 2 is provided on the left side of the top surface of the base plate 1. The condensing module 2 includes a left cover 3, a condensing fan 4, and a condenser 5. The condensing fan 4 is embedded in the left cover 3, and the condenser 5 is disposed inside the left cover 3. By integrating the left cover 3, the condensing fan 4, and the condenser 5 into a modular design, the assembly efficiency is greatly improved, as well as the subsequent disassembly and maintenance. Furthermore, it reduces space occupation and improves system integration and reliability.

[0035] Please see Figure 5-6 An electrical control module 6 is provided on the front side of the top of the base plate 1. The electrical control module 6 includes a front shell 7 and an electrical control box 8. The electrical control box 8 is embedded and fixedly installed on the front shell 7. An electrical control cover 9 is detachably provided on the front side of the electrical control box 8. Through the setting of the electrical control cover 9, the control circuit or communication module and other control systems inside the electrical control box 8 can be quickly inspected and maintained, which improves maintenance efficiency and reduces maintenance costs.

[0036] Please see Figure 5-6A bracket 10 is fixedly installed in the middle of the top surface of the base plate 1. A plate heat exchanger 11 is fixedly installed on the top surface of the bracket 10. A PTC electric heater 12 is fixedly installed below the bracket 10. By overlapping the plate heat exchanger 11 and the PTC electric heater 12 in the vertical direction, the space occupied can be reduced, thereby reducing the overall size of the device, reducing the space required for device installation, improving the applicability of the device, and enhancing its competitiveness.

[0037] Please see Figure 5-6 An electronic water pump 13 is fixedly installed on the top surface of the base plate 1 on the left side of the bracket 10, and an electric compressor 14 is fixedly installed on the top surface of the base plate 1 on the right side of the bracket 10.

[0038] Please see Figure 5-6 The bottom plate 1 has a right side cover 15 on the right side and a rear side shell 16 on the rear side. The top surfaces of the left side cover 3, the front side shell 7, the right side cover 15 and the rear side shell 16 are all provided with an upper cover plate 17. The left side cover 3, the front side shell 7, the right side cover 15, the rear side shell 16, the bottom plate 1 and the upper cover plate 17 are connected by bolts or screws to form a complete box. Through the assembled box structure, one side can be disassembled in a targeted manner according to the parts that need to be maintained, which greatly improves maintenance efficiency.

[0039] The outer casing of the condenser fan 4 is flush with the outer surface of the left cover 3, and the outer surface of the electronic control cover 9 is flush with the outer surface of the front cover 7. This not only avoids the risk of collision caused by protrusion and reduces unnecessary damage, but also reduces wind resistance, avoids reducing the flow rate of natural convection, and ensures the natural air cooling effect.

[0040] Please see Figure 5-6 The left cover 3 is connected to the inside of the housing through the condenser fan 4. Several heat dissipation holes 18 are provided on the side of the rear shell 16, the front shell 7 and the left cover 3, which are connected to the inside of the housing. By setting multiple heat dissipation holes 18, the openings for air to flow in are increased. This not only increases the path of natural convection and improves the heat dissipation effect of natural air cooling, but also makes full use of the 'collision wind' effect generated during vehicle driving to further enhance the heat dissipation effect. In addition, it can also reduce the frequency of starting the electric compressor 14, reduce wear and tear and improve the service life of the device.

[0041] Please see Figure 1-5 The front shell 7 has an inlet pipe 19 and an outlet pipe 20 on its side.

[0042] The inlet pipe 19, the electronic water pump 13, the PTC electric heater 12, the plate heat exchanger 11, and the outlet pipe 20 are connected in sequence through pipes to form a water circulation loop.

[0043] The electric compressor 14, condenser 5 and plate heat exchanger 11 are connected in sequence through pipes to form a cooling circulation loop.

[0044] The cooling circulation loop is located above the water circulation loop. By setting up two loops in upper and lower layers, the space inside the box can be fully utilized, the overall size of the device can be reduced, and the applicability can be improved.

[0045] The water circulation loop and cooling circulation loop are electrically connected to the electrical control box 8.

[0046] Please see Figure 3 , 5 Several feet 21 are fixedly provided on the lower outer sides of the front shell 7 and the rear shell 16 to enhance the overall rigidity of the device, reduce vibration and deformation during transportation and use, and improve the reliability of the connection with the vehicle chassis.

[0047] The device has the following operating modes during use:

[0048] I. Standby Mode

[0049] The device is in standby mode when the electrical appliances in the vehicle are turned off or the battery is in a suitable environment for operation due to natural convection.

[0050] II. Self-looping mode

[0051] When the battery temperature exceeds the suitable temperature, the control box 8 controls the electronic water pump 13 to start, so that the water circulation loop starts to work. The heat on the battery is removed by the water circulation, so that the battery returns to the suitable working state. At the same time, the electric compressor 14, condenser fan 4, condenser 5, and PTC electric heater 12 are turned off.

[0052] III. Cooling Mode

[0053] When the water circulation is insufficient to maintain the battery temperature at a suitable level, the electrical control box 8 restarts the electric compressor 14, causing the cooling circulation loop to start working. The battery is cooled by the superposition of the water circulation loop and the cooling circulation loop, and the battery temperature is reduced to a suitable working state.

[0054] IV. Heating Mode

[0055] When the battery temperature is lower than the suitable temperature, the control box 8 first controls the electronic water pump 13 to start, so that the water circulation loop starts to work. At the same time, the PTC electric heater 12 is turned on, so that the temperature of the circulating liquid rises, and then the heat is transferred to the battery, thereby raising the battery temperature to the suitable working state.

[0056] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as a limitation on the present invention.

[0057] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
