Description

Technical Field

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

[0002] Taking automotive air conditioning as an example, the vehicle's air conditioning system is located in the engine compartment, using flexible / rigid pipes to connect various components. The system assembly is complex, with widely distributed components, occupying considerable space and being scattered, which is unfavorable for air conditioning system installation. Although some refrigerants (such as R290) have broad application prospects in the refrigeration industry due to their excellent cooling performance, these refrigerants are flammable and explosive, requiring high levels of system sealing. Furthermore, the refrigerant at the condenser outlet of the air conditioning system may not be completely liquefied, posing a potential hazard.

[0003] Patent CN118322794A discloses a refrigeration module for a vehicle air conditioner and a vehicle having the same. The refrigeration module includes: a compressor assembly; a first heat exchanger having a first heat exchange section and a second heat exchange section, the second heat exchange section having a first heat exchange unit and a second heat exchange unit, the first heat exchange unit and the second heat exchange unit being independently arranged, a first heat exchange loop being formed between the first heat exchange section and the compression section, a second heat exchange loop being formed between the first heat exchange section and the first heat exchange unit, the outlet of the first heat exchange unit being connected to the air inlet, a third heat exchange loop being formed between the first heat exchanger and the second heat exchange unit, and a fourth heat exchange loop being formed between the second heat exchanger and the second heat exchange unit. This refrigeration module not only increases the refrigerant flow rate in the compression section but also increases the temperature of the gaseous refrigerant in the compression section, thereby improving the heat exchange efficiency of the refrigeration module during low-temperature operation. However, the structural connection method of this patent still has many exposed pipe connections, resulting in relatively high heat loss; moreover, the components within the module are relatively independent, and the structural distribution is still not compact, which may occupy a significant amount of space in the installation area.

[0004] In view of this, the present invention provides a modular integrated compressor system and a new energy vehicle. Utility Model Content

[0093] The specific implementation of this utility model is as follows:

[0094] refer to Figures 1 to 9 As shown, this utility model is an integrated refrigeration module that makes full use of the limited space inside a vehicle. Using a compressor as a carrier, it integrates a compressor, condenser 4, evaporator 3, liquid receiver 2, multiple expansion valves and sensors, and includes a bypass circuit. (Its system schematic diagram is shown below.) Figure 10 (As shown).

[0095] The main body of the refrigeration module of this utility model includes:

[0096] The compressor is a vertical scroll compressor 1, with a first mounting surface 11, a second mounting surface 12, a third mounting surface 13, and a fourth mounting surface 14 circumferentially. The receiver 2, evaporator 3, condenser 4, and controller assembly 5 are in contact with the first mounting surface 11, the second mounting surface 12, the third mounting surface 13, and the fourth mounting surface 14, respectively, thereby reducing space waste and greatly improving the system's spatial integration. Furthermore, an inlet 15, an outlet 16, a first pressure sensor interface 18, a second pressure sensor interface 19, and a first electronic expansion valve interface 17 are respectively provided on the outer periphery of the vertical scroll compressor 1. The inlet 15 communicates with the low-pressure side cavity of the compressor. The refrigerant, after compression, enters the high-pressure side exhaust cavity from the low-pressure side intake cavity, and the exhaust cavity is connected to the outlet 16. The first pressure sensor interface 18 communicates with the low-pressure side intake cavity, the second pressure sensor interface 19 communicates with the high-pressure side exhaust cavity, and the first electronic expansion valve interface 17 communicates with both the high-pressure side exhaust cavity and the low-pressure side intake cavity. The first pressure sensor 81 is threadedly connected to the first pressure sensor interface 18, the second pressure sensor 82 is threadedly connected to the second pressure sensor port 19, and the first electronic expansion valve 6 is threadedly connected to the first electronic expansion valve port 17. The first pressure sensor 81 is located in the low-pressure side intake chamber near the intake port 15, the second pressure sensor 82 is located in the high-pressure side exhaust chamber, and the first electronic expansion valve 6 is located in the high-pressure side exhaust chamber.

[0097] The first electronic expansion valve 6 corresponds to the middle section of the bypass circuit in the system. When the expansion valve is open, the high-pressure exhaust chamber and the low-pressure intake chamber will be directly connected through the expansion valve. When the expansion valve is closed, the flow channels of the high-pressure exhaust chamber and the low-pressure intake chamber are not connected.

[0098] The controller assembly 5 is used to control the operation of the integrated refrigeration system. It can be separate from the compressor. The compressor motor power supply line extends from the compressor junction box and connects to the controller wiring port 51 of the controller assembly 5. The high-voltage male terminal 52 on one side of the controller assembly 5 is the port for connecting the external compressor drive power, and the low-voltage male terminal 53 is the port for connecting the external control signals and the power supply to the control circuit.

[0099] The liquid receiver 2 has a cubic liquid storage chamber 28, a partition 27, a liquid inlet 22, a liquid outlet 21, a third pressure sensor port 24, and a second electronic expansion valve port 23. The liquid inlet 22 is located at the top of the cubic liquid storage chamber 28 and is directly connected to it. The partition 27 is located near the liquid inlet 22, at the top of the cubic liquid storage chamber 28 (forming a gas-liquid separation structure). Liquid refrigerant, under gravity, passes through the partition 27 and deposits at the bottom of the cubic liquid storage chamber 28, further liquefying any possible gases and thus improving refrigeration efficiency. The third pressure sensor port 24 and the second electronic expansion valve port 23 are located between the cubic liquid storage chamber 28 and the liquid outlet 21. The third pressure sensor 83 is threadedly connected to the third pressure sensor port 24, and the second electronic expansion valve 7 is threadedly connected to the second electronic expansion valve port 23.

[0100] The first heat exchanger (condenser 4 in this embodiment) has a first heat exchange unit and a second heat exchange unit. The circuits of the first heat exchange unit and the second heat exchange unit are independent of each other, but their structures are in close contact with each other. The inlet of the first heat exchange unit is connected to the compressor exhaust port 16, and the outlet of the first heat exchange unit is connected to the liquid inlet of the liquid receiver 2.

[0101] The second heat exchanger (evaporator 3 in this embodiment) has a third heat exchange unit and a fourth heat exchange unit. The circuits of the third heat exchange unit and the fourth heat exchange unit are independent of each other, but their structures are in close contact with each other. The inlet 32 ​​of the third heat exchange unit is connected to the drain port of the liquid receiver 2, and the outlet 31 of the third heat exchange unit is connected to the air inlet 15 of the compressor.

[0102] The first heat exchange unit (condenser 4), compressor, liquid receiver 2, and third heat exchange unit form a first heat exchange loop. The inlet 43 and outlet 44 of the second heat exchange unit are connected to external heat exchange devices, forming a second heat exchange loop. The inlet 33 and outlet 34 of the fourth heat exchange unit are respectively connected to external heat exchange devices, forming a third heat exchange loop. Heat exchange between the first and second heat exchange loops is achieved through direct contact between the first and second heat exchange units; heat exchange between the first and third heat exchange loops is achieved through direct contact between the third and fourth heat exchange units.

[0103] In the integrated refrigeration module, the inlet 41 of the first heat exchange unit of the first heat exchanger is connected to the exhaust port 16 of the compressor, and the outlet 42 of the first heat exchange unit of the first heat exchanger is connected to the inlet of the liquid receiver 2. Because the vertical scroll compressor 1, liquid receiver 2, evaporator 3, condenser 4, and controller assembly 5 in this invention all adopt a cubic shell, surface contact (gap-free face-to-face contact) is achieved, fully utilizing the limited space inside the vehicle and avoiding space waste. Furthermore, the internal structure of each component is further optimized based on the cubic shell. For example, the liquid receiver 2 uses a cubic liquid receiver chamber 2, etc. (traditional liquid receiver chambers are basically circular, easily leading to space waste), making full use of every inch of space and greatly reducing the volume of the existing compressor system. This allows for the installation of a higher-performance compressor in a smaller space, or further reduces the effective space occupied by the compressor inside the vehicle, making room for components such as the motor, electronic control system, and battery. This invention also provides a new energy vehicle using the aforementioned modular integrated compressor system. Other related technical features and effects are as described above and will not be repeated here. This invention helps to improve the overall NVH (noise, vibration, and harshness) of new energy vehicles. NVH is a comprehensive issue that measures the quality of automobile manufacturing, and it has the most direct and superficial impact on the user's experience.

[0104] This utility model has the following technical advantages:

[0105] 1. The integrated refrigeration module of this utility model has no external pipeline in the first heat exchange circuit, which effectively reduces heat loss.

[0106] 2. The integrated module of this utility model has a compact structure and small size, making it suitable for installation in small spaces.

[0107] 3. The liquid storage structure of this utility model can improve the liquefaction rate at the evaporator inlet and increase the system refrigeration efficiency.

[0108] In summary, the modular integrated compressor system of this utility model can reduce exposed piping structures by embedding the piping within the compressor body, rationally distribute various system components, improve the utilization rate of installation space, and further enhance refrigeration efficiency by adding a gas-liquid separation structure after the condenser.

[0109] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
