However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0036] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0037] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0038] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0039] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first member, component, region, layer, or portion referred to may also be referred to as the second member, component, region, layer, or portion.

[0040] For ease of description, spatial relational terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the accompanying drawings. Such spatial relational terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, an element described as being "above" or "upper" relative to another element will subsequently be "below" or "lower" relative to the other element. Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly.

[0041] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "include", "comprise" and "have" list the stated features, quantities, operations, components, elements and / or their combinations that exist, but do not exclude the existence or addition of one or more other features, quantities, operations, components, elements and / or their combinations.

[0042] Variations in the shapes shown in the drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include variations in shapes that occur during manufacturing.

[0043] The features of the examples described herein may be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0044] like Fig.11 As shown, the thermal management integrated module of the present application includes an electric compressor 100, a first pressure and temperature sensor 610, a liquid-cooled condenser 200, a liquid storage and drying tank 400, an electronic expansion valve 500 and a plate evaporator 300. Among them, the exhaust port of the electric compressor 100 is connected to the liquid inlet of the liquid-cooled condenser 200 through the first pressure and temperature sensor 610, the liquid outlet of the liquid-cooled condenser 200 is connected to the inlet of the liquid storage and drying tank 400, the outlet of the liquid storage and drying tank 400 is connected to the inlet of the electronic expansion valve 500, the outlet of the electronic expansion valve 500 is connected to the liquid inlet of the plate evaporator 300, and the air outlet of the plate evaporator 300 is connected to the air intake port 112 of the electric compressor 100 through the second pressure and temperature sensor 620.

[0045] The following is the principle of refrigeration:

[0046] The electric compressor 100 compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. The refrigerant flows through the first pressure-temperature sensor 610 and then enters the liquid-cooled condenser 200. Here, the first pressure-temperature sensor 610 has the function of monitoring the outlet temperature of the electric compressor 100. The high-temperature and high-pressure gaseous refrigerant releases heat in the liquid-cooled condenser 200, transfers the heat to the coolant in the heating circuit, and condenses itself from the high-temperature and high-pressure gaseous state to the high-temperature and high-pressure liquid refrigerant. Then, the high-temperature and high-pressure liquid refrigerant flows through the liquid storage drying tank 400, dries and absorbs the gaseous refrigerant that has not been completely condensed, and ensures that the refrigerant entering the electronic expansion valve 500 is all liquid refrigerant. Then, the dried high-temperature and high-pressure liquid refrigerant enters the electronic expansion valve 500 and is throttled to a low-temperature and low-pressure liquid refrigerant. Next, the low-temperature and low-pressure liquid refrigerant enters the plate evaporator 300 to absorb heat, absorbs heat from the coolant in the refrigeration circuit, cools it down, and evaporates from the low-temperature and low-pressure liquid refrigerant to the low-temperature and low-pressure gaseous refrigerant. Finally, the refrigerant returns to the electric compressor 100 through the second pressure-temperature sensor 620, where the second pressure-temperature sensor 620 functions to monitor the suction temperature of the electric compressor 100.

[0047] As mentioned above, compared with the system architecture of the primary circuit of the existing automobile air conditioning system, that is, the way in which the refrigerant directly enters the passenger compartment (absorbing or releasing heat), the system architecture of the secondary circuit of the present application is compatible with mainstream refrigerants such as R134a, R1234yf and R290, which expands the scope of use of the present application and improves its versatility. In addition, the secondary circuit architecture simplifies the number of components in the refrigerant circuit. At the same time, the secondary circuit architecture is adopted, and the refrigerant circuit will not enter the passenger compartment, avoiding safety problems caused by refrigerant leakage.

[0048] In addition, it is worth mentioning that before the application was filed, in the existing automobile air conditioning system (system architecture of the primary circuit), the plate evaporator 300 and the liquid-cooled condenser 200 were of regular shape. When actually arranged, the gap between the components and the compressor 100 was large, and a lot of space could not be used, resulting in a large overall size, which was not conducive to the layout of the vehicle. In addition, there were many pipe connection points during installation, the installation time was long, the space occupied was large, and the later maintenance was inconvenient.

[0049] In view of this, the first aspect of the present application provides a thermal management integrated module, which solves the problems of the existing thermal management modules of automotive air conditioners, such as large overall size, many pipe connection points, long installation time, and inconvenient later maintenance. Figures 1 to 12 A thermal management integrated module according to some embodiments of the present application is described.

[0050] like Figure 2 , Figure 3 and Figure 4As shown, the thermal management integrated module of the present application includes a compressor 100, a liquid-cooled condenser 200 and a plate evaporator 300; the compressor 100 includes a mechanical part 110 and an electrical control part 120 that are perpendicular to each other (the perpendicularity can be 90°±10°). Among them, one end of the mechanical part 110 is connected to the electrical control part 120, and the other end of the mechanical part 110 is connected to one end of the liquid-cooled condenser 200; one end of the liquid-cooled condenser 200 is designed to imitate the mechanical part 110, and the side surface of one end of the liquid-cooled condenser 200 contacts the end surface of the other end of the mechanical part 110; an exhaust port 111 is provided at the other end of the mechanical part 110, and a liquid inlet is provided at one end of the liquid-cooled condenser 200, and the exhaust port 111 of the mechanical part 110 is directly connected to the liquid inlet of the liquid-cooled condenser 200; the liquid-cooled condenser 200 is parallel to the electrical control part 120, and the mechanical part 110, the electrical control part 120 and the liquid-cooled condenser 200 are surrounded to form an installation space; the plate evaporator 300 is arranged in the installation space, and the air outlet of the plate evaporator 300 is directly connected to the air intake port 112 of the mechanical part 110.

[0051] As described above, the liquid-cooled condenser 200 of the present application is designed to be a contoured structure with reference to the appearance of the compressor 100, such as Figure 2 , Figure 3 and Figure 4 As shown, the mechanical part 110 is approximately cylindrical, and one end of the liquid-cooled condenser 200 is designed in the shape of the cylinder (the cross section of one end of the liquid-cooled condenser 200 is a residual circle, and the rest of the part and the cross section are rectangular, as shown in FIG. Fig.10 As shown), the side surface of one end of the liquid-cooled condenser 200 contacts the end surface of the other end of the mechanical part 110, so that the exhaust port 111 of the mechanical part 110 is directly connected to the liquid inlet of the liquid-cooled condenser 200. In this way, compared with the regular liquid-cooled condenser 200 in the prior art, there will be no gap between the liquid-cooled condenser 200 of the present application and the compressor 100, and there will be no additional structure that exceeds the mechanical part 110. On this basis, no additional pipeline connection is required, thereby making the overall structure compact. Furthermore, the plate evaporator 300 is sequentially arranged in the installation space and is directly connected to the air intake port 112 of the mechanical part 110. In this way, there will be no gap between the plate evaporator 300 and the compressor 100, and no additional pipeline connection is required.

[0052] That is to say, the liquid-cooled condenser 200 and the plate-type evaporator 300 of the present application fully utilize the space around the compressor 100, and both are directly connected to the air intake port 112 and the air exhaust port 111 of the compressor 100, which makes the overall structure after being assembled with the compressor 100 compact. At the same time, there is no need to connect additional pipelines, which also reduces the risk of system leakage and improves the ease of assembly and the convenience of subsequent maintenance.

[0053] It is also worth mentioning that the liquid-cooled condenser and plate evaporator of the present application are different from the heat exchanger structure commonly used in traditional air-conditioning boxes. The present application is an integrated structure designed based on the liquid-cooled condenser and plate evaporator in the thermal management integrated module.

[0054] Further, in the embodiments of the present application, Figure 2 , Figure 3 and Figure 4 As shown, the liquid storage dry tank 400 and the electronic expansion valve 500 are both arranged in the installation space, and the liquid storage dry tank 400 and the electronic expansion valve 500 are both arranged on the mechanical part 110; the other end of the liquid cooling condenser 200 is provided with a liquid outlet, and the liquid outlet of the liquid cooling condenser 200 is directly connected to the inlet of the liquid storage dry tank 400; the outlet of the liquid storage dry tank 400 is connected to the inlet of the electronic expansion valve 500, and the outlet of the electronic expansion valve 500 is directly connected to the liquid inlet of the plate evaporator 300. Figure 2 and Figure 3 As shown, the first pressure-temperature sensor 610 is integrated at the exhaust port of the mechanical part 110 , and the second pressure-temperature sensor 620 is integrated at the intake port of the mechanical part 110 .

[0055] In the embodiments of the present application, for example, Fig. 9 As shown, the end surface of one end of the liquid storage dry tank 400 contacts the side surface of the other end of the liquid cooling condenser 200; one end of the liquid storage dry tank 400 is provided with a liquid storage inlet pipe 430 protruding relative to itself, and the liquid storage inlet pipe 430 is plugged into the liquid outlet of the liquid cooling condenser 200 ( Fig. 9 The first sealing ring 440 is pressed between the liquid storage inlet pipe 430 and the liquid outlet of the liquid-cooled condenser 200; the second sealing ring 450 is sleeved on the liquid storage inlet pipe 430 and pressed between the end face of one end of the liquid storage drying tank 400 and the side face of the other end of the liquid-cooled condenser 200.

[0056] In this way, when the liquid storage inlet pipe 430 of the liquid storage drying tank 400 is plugged into the liquid outlet of the liquid-cooled condenser 200, a sealing form of a combined gasket + a single O-ring (a first sealing ring 440 + a second sealing ring 450) is adopted. Compared with a pure end face seal or a radial seal, a single size deviation will cause the sealing structure to fail. The combined sealing form can ensure better sealing, while realizing end face sealing and radial sealing. Moreover, when any single size is out of tolerance, the overall sealing structure will still not fail, thereby reducing the leakage rate between components, increasing the operating life of the system, and reducing the maintenance frequency.

[0057] In the embodiments of the present application, for example, Figure 3 and Fig.10As shown, a condenser liquid inlet pipe 220 protruding relative to the liquid-cooled condenser 200 is provided at one end thereof, the condenser liquid inlet pipe 220 is plugged into the exhaust port 111 of the mechanical part 110, and the first sealing ring is pressed between the condenser liquid inlet pipe 220 and the exhaust port 111 of the mechanical part 110. Similarly, the second sealing ring is sleeved on the condenser liquid inlet pipe 220 and pressed between the side surface of one end of the liquid-cooled condenser 200 and the end surface of one end of the mechanical part 110.

[0058] In the embodiments of the present application, for example, Figure 4 As shown, the side of the plate evaporator 300 contacts the side of the mechanical part 110; one side of the plate evaporator 300 is provided with an air outlet pipe protruding relative to itself, the air outlet pipe is plugged into the air inlet 112 on one side of the mechanical part 110, and the first sealing ring is pressed between the air outlet pipe and the air inlet 112 of the mechanical part 110. Similarly, the second sealing ring is sleeved on the air outlet pipe and pressed between the side of the plate evaporator 300 and the side of the mechanical part 110.

[0059] Further, in the embodiments of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the thermal management integrated module further includes a cover 800. The edge of the cover 800 is sealed and connected to the edge of the mechanical part 110, the electric control part 120 and the liquid-cooled condenser 200 to form a sealed closed space; the plate evaporator 300, the liquid storage drying tank 400, the electronic expansion valve 500, the exhaust port 111 of the mechanical part 110, the air intake port 112 of the mechanical part 110 and the liquid outlet of the liquid-cooled condenser 200 are all arranged in the closed space.

[0060] Preferably, if Figure 1 and Figure 4 As shown, the cover 800 includes a first shell 810 and a second shell 820, and the first shell 810 and the second shell 820 are symmetrically arranged; the first shell 810 and the second shell 820 are plugged into each other and are sealed with the edges of the mechanical part 110, the electrical control part 120 and the liquid-cooled condenser 200 through a groove structure.

[0061] In this embodiment, the trough structure includes a docking groove and a docking convex eaves. Fig.12 As shown, the side eaves of the mechanical part 110, the electric control part 120 and the liquid-cooled condenser 200 are all provided with a butt-jointed convex eaves 740; Figure 8 As shown, the first housing 810 and the second housing 820 are both provided with a docking groove 730, and the docking groove 730 of the first housing 810 and the second housing 820 is plugged into the docking protrusion 740 of the mechanical part 110, the electric control part 120 and the liquid-cooled condenser 200. Figure 4 and Figure 3 As shown, a first sealing strip 710 is provided between the docking groove 730 and the docking protrusion 740 to achieve better sealing.

[0062] In addition, the portions where the first housing 810 and the second housing 820 butt against each other are also connected via a slot structure. For example, Fig.12 As shown, the side eaves of the docking portion of the second shell 820 are provided with docking grooves 730, and the side eaves of the docking portion of the first shell 810 are provided with docking convex eaves (the first shell 810 is not shown in the figure). Figure 4 and Figure 3 As shown, a second sealing strip 720 is provided between the docking groove 730 and the docking protrusion to achieve better sealing.

[0063] As described above, the cover 800 is tightly matched with the thermal management integrated module through the rib-groove structure, and a sealing rubber is designed inside the rib-groove structure to ensure the internal airtightness of the thermal management integrated module after the outer cover 800 is assembled in place.

[0064] Furthermore, if Figure 3 and Figure 8 As shown, a refrigerant sensor 900 is arranged on the outer cover 800 of the thermal management integrated module. The refrigerant sensor 900 is set in a closed space and is used to detect the refrigerant leakage in the closed cover 800 (detect the refrigerant information in the closed space). Figure 5 As shown, the wiring harness of the internal electrical components passes through the wiring harness sealing rubber sleeve 812 and is connected to the outside, and the two coolant inlet and outlet pipes of the plate evaporator 300 pass through the pipeline sealing rubber sleeve 811 and are connected to the external pipeline.

[0065] In addition, if Figure 2 As shown, in the embodiment of the present application, the thermal management integrated module further includes an external pipeline 410. The outlet of the liquid storage drying tank 400 is connected to the inlet of the electronic expansion valve 500 through the external pipeline 410 (eg Figure 7 As shown, the liquid storage drying tank outlet 460), the external pipe 410 is provided with a high-pressure filling port 420, and the high-pressure filling port 420 is used to add refrigerant during system maintenance.

[0066] According to a second aspect of the present application, there is provided an automobile air conditioning system, comprising the thermal management integrated module as described above. The thermal management integrated module is arranged in the front cabin of the automobile.

[0067] The secondary circuit system architecture of the present application is compatible with mainstream refrigerants such as R134a, R1234yf and R290, which expands the scope of application of the present application and improves its versatility. In addition, the secondary circuit architecture simplifies the number of components in the refrigerant circuit. At the same time, the secondary circuit architecture is adopted, and the refrigerant circuit will not enter the passenger compartment, avoiding safety problems caused by refrigerant leakage.

[0068] The thermal management integrated module of the present application designs the shape of the heat exchanger according to the shape of the compressor, thereby adopting a special-shaped heat exchanger, which maximizes the use of the space around the compressor, making the integrated module more compact and meeting more layout scenarios.

[0069] The thermal management integrated module of the present application designs all components such as heat exchangers, valves, sensors, etc. to the outside, which is conducive to the replacement of various components according to various working conditions, improves the adaptability of the thermal system integrated module assembly, and can iterate products that meet the needs in a short period of time according to the needs of different vehicle models, shortening the development cycle and costs, and facilitating product platformization.

[0070] The thermal management integrated module of the present application integrates all the refrigerant circuit components, and is designed with a sealed cover on the outside, and a concentration sensor is arranged inside to monitor refrigerant leakage. This allows the refrigerant to be identified in time once it has reached a set concentration, which is different from the conventional pressure monitoring method of the refrigerant circuit. The identification is faster, and there is no need to start the vehicle, which is safer.

[0071] The components of the thermal management integrated module of the present application all use a combined gasket + single O-ring sealing form to seal. Compared with pure end face sealing or radial sealing, a single size deviation will cause the sealing structure to fail. The combined sealing form can ensure better sealing, and when any single size is out of tolerance, the overall sealing structure will not fail.

[0072] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application rather than to limit them. The protection scope of the present application is not limited thereto.
