Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted refrigeration equipment, specifically to integrated air conditioning systems and new energy vehicles. Background Technology

[0002] With the emergence of new refrigerants, R290 has become the preferred option among fourth-generation HFO refrigerants, and it has a very broad application market. However, due to its flammability, R290 has extremely stringent requirements for the system's leak prevention capabilities and safety.

[0003] CN205615302U introduces a novel heat pump air conditioning system for passenger vehicles, consisting of three heat exchangers with different structures: an external heat exchanger, a first internal heat exchanger, and a second internal heat exchanger; a one-way shut-off valve; an oil separator; a four-way reversing valve; first, second, and third two-position three-way valves; a coaxial tube; and a throttling device and its connecting pipes, forming the main air conditioning circuit. The throttling device includes first and second short-pipe throttling valves. Furthermore, an oil separator is added to the main air conditioning circuit to address the problem of poor oil return from the compressor at low temperatures; a coaxial tube is installed to improve heat exchange capacity and includes an enthalpy-increasing inlet; it can solve the problems of uneven refrigerant flow distribution, poor drainage, and easy frosting in low-temperature environments; it allows for free switching between cooling and heating modes of the heat pump system; it reduces the number of circulation and control loops and components, saving space and costs; and it provides a comfortable driving and riding space, making it suitable for pure electric and hybrid new energy vehicles.

[0004] Current heat pump air conditioning systems generally consist of two parts: an air conditioning system that provides cooling and a PTC heating system that provides heating. These are controlled by separate control systems and located in different parts of the vehicle. Although they can be connected by piping, this arrangement occupies a significant amount of space. This layout has several drawbacks: firstly, the piping increases the risk of refrigerant leakage, which is particularly critical for vehicle air conditioning systems using R290 refrigerant, requiring further reduction in leakage possibilities; secondly, the existing structure still has considerable room for improvement in terms of installation efficiency, connection reliability, ease of maintenance, and refrigerant transmission resistance and heat loss; and thirdly, the separate control of the air conditioning system and the PTC system wastes resources, necessitating an additional control system for coordinated use of both.

[0005] In view of this, the present invention provides an integrated air conditioning system and a new energy vehicle. Utility Model Content

This utility model aims to solve the problem of applying R290 refrigerant in vehicle air conditioning systems. Given the flammability of R290 refrigerant, its use requires strict safety precautions. Therefore, this utility model proposes an integrated air conditioning system structure.

At the same time, it simplifies the assembly process, improves assembly efficiency, reduces system pipeline connection points, eliminates all unnecessary refrigerant leakage points, and enhances safety and ease of use.

[0058] In a preferred embodiment, the gap between the first side of the heating module housing and the control circuit board 60 forms a heat-insulating plane, but this is not a limitation.

[0059] This invention proposes an integrated air conditioning system structure that eliminates traditional piping design and directly integrates all components of the air conditioning system using a plug-in connection method. This structure significantly shortens the refrigerant flow path, substantially reduces the number of leakage points, and improves installation efficiency and space utilization. Furthermore, the integration of the air conditioning system and the PTC heating system allows for unified management and control, making the entire thermal management module more efficient. When the air conditioning system is operating at extremely low temperatures, the heating module simultaneously compensates for the increased heating capacity. This design facilitates installation, operation, and subsequent maintenance, and fundamentally improves the safety and comfort of the air conditioning system.

[0060] The specific embodiments of this utility model are as follows:

[0061] This utility model proposes an integrated vehicle air conditioning system structure. For example... Figures 1 to 5As shown, the system adopts a modular layout, and can be divided into five modules: compressor, condenser 3, receiver 1, evaporator 2, and heating module 7. The entire system exchanges heat with the outside through the water-side inlet 75 and water-side outlet 76 on the condenser 3, evaporator 2, and heating module 7. The modules are connected in a modular fashion, eliminating all unnecessary connections, minimizing system leakage points, improving installation efficiency and space utilization, and ensuring safety during use. Simultaneously, the air conditioning and heating systems are unified and controlled by a single control board, resulting in a highly integrated thermal management system that improves coordination efficiency and system comfort. The compressor is connected to the bottom bracket, connecting the entire air conditioning system to the vehicle.

[0062] Continue to refer to Figure 6 The bottom of the receiver 1 has a connecting seat for connecting and fixing to the compressor module. The refrigerant flows through the receiver 1 via the receiver outlet pipe 12 and the receiver inlet pipe 13. The receiver 1 also integrates an expansion valve (not shown in the figure), so the refrigerant has already expanded and depressurized when it flows out of the receiver 1. The connecting lugs at the bottom of the receiver 1 are connected and fixed to the first connecting seat 44 of the receiver 4 on the front shell and the second connecting seat 53 of the receiver 5 on the middle shell. The receiver 1 is connected and fixed via connecting lugs on both sides, the condenser 3 and the evaporator 2. The top of the receiver 1 has a liquid level observation window for monitoring the refrigerant level inside the receiver, which can be located on the top or side.

[0063] Continue to refer to Figure 7 Evaporator 2 is provided with evaporator inlet pipe 21 and evaporator outlet pipe 22 for refrigerant to pass through; second water side inlet 23 and second water side outlet 24 are used for cooling water to pass through. Cooling water and refrigerant complete heat exchange in evaporator 2. The connecting lug at the bottom of evaporator 2 is connected and fixed to the first evaporator connecting seat 54 and the second evaporator connecting seat 65 of the compressor. The connecting lug at the end of evaporator 2 is fixedly connected to the connecting lug of liquid receiver 1. In this embodiment, the liquid receiver 1 and the evaporator 2 are two cubes with their sides touching each other. The two ends of the combination of the liquid receiver 1 and the evaporator 2 are held between the second extension 69 of the plate-shaped controller chamber 64 and the first extension 37 of the plate-shaped condenser 3 (the two opposite end faces of the liquid receiver 1 and the evaporator 2 are respectively attached to the side of the second extension 69 of the controller chamber 64 and the side of the first extension 37 of the condenser 3). Compared with the traditional barrel-shaped liquid receiver, the volume of the liquid receiver 1 is greatly increased, and the volume of the evaporator 2 is effectively expanded, thereby making full use of the limited space above the horizontal compressor housing, greatly enhancing the space utilization rate, and improving the COP (Coefficient of Performance) efficiency of the compressor.

[0064] Continue to refer to Figure 8 The refrigerant flows within the condenser 3 through the first refrigerant-side inlet 32 ​​and the first refrigerant-side outlet 31. Cooling water flows through the condenser through the first water-side inlet 33 and the first water-side outlet 34. Heat exchange between the water and refrigerant sides is achieved inside the condenser using coils or fins. The first screw-in hole 35 around the condenser 3 is used for connection to the compressor. The condenser 3 is connected and fixed to the receiver 1 through the receiver fixing hole.

[0065] The compressor consists of a front casing 4, a stationary disc (not shown in the diagram), a middle casing 5, a rear casing 6, and a rear cover plate 66. (Continue to refer to...) Figure 9 The front housing 4 has a first connector 44 for the liquid receiver, and also has a compressor exhaust port 41. The direction of the exhaust port 41 is consistent with the axial direction of the compressor. Next to it is a sensor mounting hole 42 that communicates with the exhaust port 41 for mounting a sensor. The front housing 4 also has a second screw-in hole 43 for axial connection of the compressor.

[0066] Continue to refer to Figure 10 The middle shell 5 is provided with a set of liquid receiver second connecting seats 53 and a set of evaporator first connecting seats 54, which are used to fix evaporator 2 and liquid receiver 1 respectively. The tube feet at the bottom of the compressor are used to connect with the bracket, and the third screw connection through hole 62 ensures the axial connection of the compressor.

[0067] Continue to refer to Figure 11 The rear housing 6 is provided with an evaporator second connection seat 65 for connecting the evaporator 2, a parallel air intake 63 and a sensor mounting port, which are perpendicular to the compressor axial direction. A third screw connection hole 62 is used to fix the mounting bolts that pass through the second screw connection hole 43 and the bolt pin 52. The high voltage male terminal 67 and the low voltage male terminal 68 are located on the side of the compressor and are connected to the vehicle power supply system.

[0068] Continue to refer to Figures 12 to 14As shown, the heating module 7 includes a heating module housing, a power supply electrode 78, a heating plate 77, and a heat exchange channel 73. The first side of the heating module housing mates with the rear shell 6 of the compressor housing to form a mating space 79 for accommodating the control circuit board 60. The second side of the heating module housing is provided with the heating plate 77 and the heat exchange channel 73, and the heating plate 77 is electrically connected to the control circuit board 60. The second side of the heating module housing is isolated into a first cavity 71 and a second cavity 72, thereby preventing water ingress and short circuit in the second cavity 72. The first cavity 71 has several integrally formed bent sidewalls, and the heat exchange channel 73 is formed between the bent sidewalls. The heat exchange channel 73 connects the water-side inlet 75 and the water-side outlet 76 of the heating module 7. The second cavity 72 is provided with a wiring through-hole 74. The power supply electrode 78 of the heating plate 77 is connected to the control circuit board 60 through the wiring through-hole 74, so that the compressor's control circuit board 60 can directly control the operation of the heating module 7. The heating plate 77 is separated from the control circuit board 60 by a heat exchange channel 73 and a heating module housing, preventing heat transfer to the control circuit board 60. The heating plate 77 can use film heating instead of PTC heating; thick or thin film heating is optional, saving more space. The gap between the first side of the heating module housing and the control circuit board 60 forms a heat-insulating plane, further preventing heat transfer to the control circuit board 60. The heat exchange channel 73 adopts a serpentine S-shaped flow channel to ensure optimal heat exchange. Furthermore, this invention allows the control circuit board 60 in the compressor to control the operating states of the compressor, expansion valve, and heating plate 77 separately (i.e., one PCB board controls the operating states of multiple different temperature control systems), further reducing the number of components, enhancing circuit integration, saving space and cost, and overcoming the limitations of existing technologies.

[0069] The integrated air conditioning system of this patent does not use pipes to connect the modules. Instead, the modules are connected by splicing and then fixed with bolts. During installation, the first step is to install the compressor and heating module 7. The heating module 7 is installed on the side of the controller chamber 64 away from the compressor cavity.
