Description

Technical Field

[0001] The present invention relates to the field of vehicle refrigeration equipment, and more specifically, to an integrated air conditioning system and a new energy vehicle. Background Art

[0002] With the emergence of new refrigerants, R290 has become an excellent option among the fourth-generation refrigerants HFOs, and it has an extremely broad application market. However, due to its flammability, R290 has extremely stringent requirements for the leak prevention ability and safety of the system.

[0003] CN205615302U discloses a new type of passenger vehicle heat pump air conditioning system, which consists of three heat exchangers with different structures: an external heat exchanger, a first internal heat exchanger, a second internal heat exchanger, and a one-way check valve; an oil separator; a four-way reversing valve; first, second, and third two-way three-way valves; a coaxial tube; a throttling device and its connecting pipelines to form the main air conditioning circuit; the throttling device includes a first and a second short tube throttle valve. In addition, an oil separator is added to the main air conditioning circuit to solve the problem of poor compressor oil return at low temperatures, a coaxial tube is provided to improve the heat exchange capacity and an enthalpy-increasing inlet is provided; it can solve the problems of uneven refrigerant flow distribution, poor drainage, and easy frosting in a low-temperature environment; it can realize the free switching between the refrigeration and heating working conditions of the heat pump system; it reduces the number of circulation and control circuits and components, saves space and cost; it can provide a comfortable driving space inside the vehicle and is suitable for use in pure electric and hybrid new energy vehicles.

[0004] The current heat pump air conditioning system generally consists of two parts, an air conditioning system for refrigeration and a PTC heating system for heating, which are respectively controlled by two sets of control systems and are respectively arranged at different positions inside the vehicle. Although they can be connected through pipelines, they will occupy a large amount of space on the vehicle. There are some deficiencies in such an arrangement: the existence of pipelines increases the risk of refrigerant leakage, which is particularly critical for the vehicle air conditioning system using R290 refrigerant, and the possibility of leakage needs to be further reduced; secondly, there is still much room for improvement in terms of installation and layout efficiency, connection reliability, convenience of later maintenance, as well as refrigerant transmission resistance and heat loss in the existing structure; thirdly, the separate control of the air conditioning system and the PTC wastes resources and requires an additional control system to make overall arrangements for their use.

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

[0106] The present invention proposes an integrated air-conditioning system structure. By canceling the traditional pipeline design and adopting a direct plug-in connection method, the components of the air-conditioning system are directly integrated. This structure significantly shortens the refrigerant circulation path, significantly reduces the number of leakage points, and at the same time improves the installation efficiency and space utilization rate. In addition, the air-conditioning system and the PTC heating system are integrated and uniformly managed and controlled, making the entire thermal management module work more efficiently. When the air-conditioning system is heating at ultra-low temperature, the heating module is synchronously used to compensate the heating capacity. This design facilitates installation operation and later maintenance management, and fundamentally improves the safety and comfort of the air-conditioning system.

[0107] The specific implementation manners of the present invention are as follows:

[0108] The present invention proposes an integrated vehicle-mounted air-conditioning system structure. As Figures 1 to 5As shown, the system adopts a modular layout and can be generally divided into five modules: a compressor, a condenser 3, a liquid receiver 1, an evaporator 2, and a heating module 7. The entire system exchanges heat with the outside through the water-side inlets 75 and water-side outlets 76 on the condenser 3, the evaporator 2, and the heating module 7. The connection method between each module is like building blocks, eliminating all unnecessary connection structures, minimizing the leakage points of the system, improving the installation efficiency and space utilization rate, ensuring safety during use, and unifying the air-conditioning system and the heating system, which are controlled by a single control board, making the thermal management system highly integrated and improving the collaborative efficiency and system comfort. The compressor is connected to the bottom bracket to connect the entire air-conditioning system to the vehicle.

[0109] Continue to refer to Figure 6 , a connection seat is arranged at the bottom of the liquid receiver 1 for connecting and fixing with the compressor module. The refrigerant flows through the liquid receiver 1 via the liquid receiver outlet pipe 12 and the liquid receiver inlet pipe 13, and an expansion valve (not shown in the figure) structure is integrated inside the liquid receiver 1. When the refrigerant flows out of the liquid receiver 1, the expansion and pressure reduction have been completed. The connecting ear plates at the bottom of the liquid receiver 1 are connected and fixed to the first liquid receiver connection seat 44 of the front shell 4 and the second liquid receiver connection seat 53 of the middle shell 5. The liquid receiver 1 is connected and fixed through the connecting ear plates arranged on both sides and the connecting ear plates of the condenser 3 and the evaporator 2. The top of the liquid receiver 1 is a liquid level observation window for monitoring the volume of the refrigerant in the liquid receiver, which can be arranged at the top or on the side.

[0110] Continue to refer to Figure 7 , an evaporator inlet pipe 21 and an evaporator outlet pipe 22 are arranged on the evaporator 2 for the refrigerant to pass through; the second water-side inlet 23 and the second water-side outlet 24 are for the cooling water to pass through. The cooling water and the refrigerant complete heat exchange in the evaporator 2. The connecting ear plates at the bottom of the evaporator 2 are connected and fixed to the first evaporator connection seat 54 and the second evaporator connection seat 65 of the compressor. The connecting ear plates at the end of the evaporator 2 are fixedly connected to the connecting ear plates of the liquid receiver 1. In this embodiment, the liquid receiver 1 and the evaporator 2 are two cubes that are mutually attached to the sides. And the two ends of the combination of the liquid receiver 1 and the evaporator 2 are clamped between the extension part 69 of the plate-shaped controller chamber 64 and the extension part 37 of the plate-shaped condenser 3 (the two mutually facing end faces of the liquid receiver 1 and the evaporator 2 are respectively attached to the side faces of the extension part 69 of the controller chamber 64 and the extension part 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, thus making full use of the limited space above the horizontal compressor housing, greatly enhancing the space utilization rate, and improving the COP (abbreviation for Coefficient Of Performance, i.e., performance coefficient) efficiency of the compressor.

[0111] Continue to refer to Figure 8, the refrigerant completes its flow in the condenser 3 through the first agent side inlet 32 and the first agent side outlet 31. The cooling water flows through the condenser via the first water side inlet 33 and the first water side outlet 34. Inside the condenser, heat exchange between the water side and the agent side is carried out in the form of coils or fins. The screwed through holes around the condenser 3 are used to connect to the compressor, and the condenser 3 is connected and fixed to the connecting ear plate of the accumulator 1 through the accumulator fixing holes.

[0112] The compressor consists of a front shell 4, a stationary plate (not shown in the figure), a middle shell 5, a rear shell 6, a rear cover plate 66, etc. Continuing to refer to Figure 9 , a first accumulator connection seat 44 is arranged on the front shell 4, and an exhaust port 41 of the compressor is also arranged on the front shell 4. The direction of the exhaust port 41 is consistent with the axial direction of the compressor. There is also a sensor mounting hole 42 beside it that communicates with the exhaust port 41 for installing a sensor. There are also screwed through holes 43 on the front shell 4 for axial connection of the compressor.

[0113] Continuing to refer to Figure 10 , a group of second accumulator connection seats 53 and a group of first evaporator connection seats 54 are arranged on the middle shell 5, which are used to fix the evaporator 2 and the accumulator 1 respectively. On it, the pins at the bottom of the compressor are used to connect to the bracket, and the screwed through holes 62 ensure the axial connection of the compressor.

[0114] Continuing to refer to Figure 11 , a second evaporator connection seat 65 for connecting the evaporator 2 is arranged on the rear shell 6, along with parallel suction ports 63 and sensor mounting ports, which are perpendicular to the axial direction of the compressor at the same time. The screwed through holes 62 are used to fix the mounting bolts passing through the screwed through holes 43 and the bolt pins 52. The high - voltage male terminal 67 and the low - voltage male terminal 68 are located on the side of the compressor to connect to the vehicle's power supply system.

[0115] Continuing 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 flow channel 73. The first side of the heating module housing is aligned with the rear shell 6 of the compressor housing to form an accommodation space 79 for accommodating the control circuit board 60. The second side of the heating module housing is provided with a heating plate 77 and a heat exchange flow 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 partitioned into a first cavity 71 and a second cavity 72 to prevent water from entering the second cavity 72 and causing a short circuit. A plurality of integrally formed bent side walls are provided in the first cavity 71, and a heat exchange flow channel 73 is formed between the bent side walls. The heat exchange flow channel 73 communicates with the water side inlet 75 and the water side outlet 76 of the heating module 7. A wiring through hole 74 is provided in the second cavity 72, and the power supply electrode 78 of the heating plate 77 is connected to the control circuit board 60 through the wiring through hole 74 passing through the heating module 7, so that the control circuit board 60 of the compressor can directly control the working condition of the heating module 7. The heating plate 77 and the control circuit board 60 are separated by the heat exchange flow channel 73 and the heating module housing to avoid heat transfer to the control circuit board 60. The heating plate 77 can use film heating instead of PTC heating, and optionally, it can be thick film or thin film, which can save more space. The gap between the first side of the heating module housing and the control circuit board 60 forms a heat insulation plane to further avoid heat transfer to the control circuit board 60. The heat exchange flow channel 73 adopts a serpentine S-shaped flow channel to ensure the best heat exchange effect. Moreover, in the present invention, the working states of the compressor, the expansion valve, and the heating plate 77 can be respectively controlled by the control circuit board 60 in the compressor (that is, one PCB circuit board controls the working states of multiple different temperature control systems), further reducing the number of components, enhancing the integration of the circuit, saving space and cost, and breaking through the difficulties of the prior art.
