Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a thermal management integrated module and an electric vehicle. Background Art

[0002] New energy vehicles have a low range in winter, and the heating energy consumption of electric heating is high. The current refrigerant R134a faces regulatory pressure and needs to be replaced; the R134a / R1234yf heat pump system has a narrow operating range and cannot be used in low temperature environments below -15°C. At the same time, new energy vehicles have higher cooling and heating requirements, and there are many devices / components that require cooling and heating. Since the components in the current thermal management system are scattered, the compressor, heat exchanger, expansion valve and other components are connected by pipes, which has a high risk of refrigerant leakage and a large refrigerant charge.

[0003] R290 (propane) is a natural refrigerant that is expected to be promoted in passenger cars. It is harmless to the environment, has good low-temperature heating performance, and is low in cost. Its boiling point at standard atmospheric pressure is lower than that of R134a and R1234yf, and its critical temperature is equivalent to that of R134a. It is a refrigerant with relatively ideal thermal performance. However, R290 is a flammable refrigerant. Based on the application experience of other industries, its filling amount in a single system will be strictly limited. And the risk of leakage during use needs to be controlled.

[0004] The use of an indirect refrigeration system, such as heat exchange between a refrigerant and a coolant, and then transmitting the hot and cold fluids to various parts of the vehicle to achieve cooling and heating functions, and using connection interfaces to directly connect components, can solve the problems of high leakage risk and large refrigerant filling. Compared with direct heat exchange, the disadvantages of indirect heat exchange are low heat exchange efficiency and heat exchange losses. During the system startup phase, due to the large heat capacity of the refrigerant, it takes longer to achieve a certain cooling and heating effect than the direct heat exchange system, and the overall COP (ratio between cooling capacity and input power) is low. In an indirect refrigeration system, the compressor is the core component of the system. Its operating speed and power on and off need to accept instructions from the host computer. It does not integrate functions such as sensor data reception and expansion valve control. Multiple electronic control units (ECUs) work together and transmit commands to each other. It is difficult to optimize the system energy efficiency, reliability, and cost. At the same time, the compressor suction and exhaust ports are directly connected to the heat exchanger. In a limited installation space, the vibration of the compressor may have an adverse effect on the reliability of the interface.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0044] The thermal management integrated module of the utility model adopts a flow channel plate to realize the connection between various components, and there is no need to use pipes between the various components, thereby reducing the risk of refrigerant leakage; at the same time, the heat regenerator used can, on the one hand, increase the supercooling degree before the valve and improve the cooling capacity, thereby reducing the required speed or displacement of the compressor, and on the other hand, it can increase the length of the supercooling section, thereby realizing the function of storing excess refrigerant and dealing with minor leaks; the most important thing is that the thermal management integrated module can adjust the second expansion valve during the ultra-low temperature heating and heating startup stages, so that part of the gas discharged from the exhaust port of the compressor flows directly from the second expansion valve to the intake port of compressor 2, so as to widen the lowest heating temperature of the system.

[0045] The structure of the thermal management integrated module and the electric vehicle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It can be understood that the various specific embodiments are not intended to limit the protection scope of the present invention.

[0046] Figure 1 and Figure 2 This is a schematic diagram of the structure of a thermal management integrated module according to an embodiment of the present utility model. Figure 3 and Figure 4 They are respectively a top view of a thermal management integrated module and a structural schematic diagram of a condenser of an embodiment of the utility model, wherein the thermal management integrated module includes a flow channel plate 1, a compressor 2, a condenser 3, a heat regenerator 4 and an evaporator 5; the flow channel plate 1 can be regarded as having multiple channels arranged inside, and the outlet and inlet of each channel are arranged on the plate, and accordingly, the interfaces of the compressor 2, the condenser 3, the heat regenerator 4, the evaporator 5, the first expansion valve 7 and the second expansion valve 6 can be directly connected to the outlet and inlet of the corresponding channels on the flow channel plate 1.

[0047] In this embodiment, the flow channel plate 1 is provided with a first channel AA', a second channel BB', a third channel CC', a fourth channel DD', a first coolant inlet HA and a first coolant outlet HE, a second coolant inlet CA and a second coolant outlet CE. Of course, the flow channel plate 1 is also provided with a high-pressure filling port H connected to the first channel AA' and a low-pressure filling port L connected to the third channel CC', see Figure 1As shown, the high-pressure filling port H and the low-pressure filling port L are used for filling refrigerant and taking pressure during maintenance. The first expansion valve 7 is arranged in the second channel BB', that is, at the outlet of the refrigerant channel of the regenerator 4 and the refrigerant inlet of the evaporator 5, and is used to control the flow from the regenerator to the evaporator; when the thermal management integrated module of the utility model is applied to a vehicle, the first refrigerant inlet HA and the first refrigerant outlet HE form a loop with the first refrigerant of the vehicle, and the second refrigerant inlet CA and the second refrigerant outlet CE form a loop with the second refrigerant of the vehicle, so as to realize the heat exchange between the refrigerant flowing in the thermal management integrated module and the refrigerant of the vehicle. The first refrigerant and the second refrigerant of the vehicle can be hot refrigerant and cold refrigerant respectively. The hot and cold refrigerants in the indirect system are relative, and a part of them flows through the heat exchangers such as the condenser and the radiator that need to be heated / dissipated, and a part of them flows through the heat exchangers such as the evaporator and the battery electric drive that need to be cooled / absorbed. In the heating mode, the refrigerant of the condenser will flow through the heat exchangers in the cabin / battery and other positions to realize the heating function. The refrigerant of the evaporator flows through the front-end module radiator to absorb heat / de-electrically absorb heat and complete evaporation. In the cooling mode, the hot refrigerant flows to the front-end module to dissipate heat, and the cold refrigerant flows to the location that needs cooling to achieve refrigeration. The utility model mainly describes that the thermal management integrated module generates cold and hot fluids for use.

[0048] The thermal management integrated module of the utility model is provided with a hot gas bypass circuit, that is, the flow channel plate 1 is provided with a fourth channel DD', and the fourth channel DD' is connected to the exhaust port of the compressor, the condenser and the air intake port of the compressor. The thermal management integrated module also includes a second expansion valve 6, which is arranged in the fourth channel DD', and when ultra-low temperature heating is required, the second expansion valve 6 controls the flow rate of the refrigerant from the exhaust port of the compressor to the condenser and the air intake port of the compressor respectively, and the flow rate of the main refrigerant circuit and the superheat of the evaporator outlet are controlled by the first expansion valve 7.

[0049] Figure 5The schematic diagram of the structure of the condenser of one embodiment of the utility model is shown in FIG. 3. The condenser 3 has two channels. In the utility model, the channel connected with the refrigerant of the compressor is defined as the condenser 3 refrigerant channel, and the channel connected with the vehicle coolant is defined as the condenser 3 coolant channel. In this embodiment, the two ends of the refrigerant channel of the condenser 3 are port 31, port 32 and port 35, respectively. Port 31 is connected with port 35. The two ends of the coolant channel of the condenser 3 are port 33 and port 34, respectively. The flow channel plate 1 is provided with the condenser 3 at a gap H3, so that the port 31 of the refrigerant channel of the condenser 3 can be directly connected with the exhaust port of the compressor 2 through the gap H3. The two ends of the fourth channel DD' are respectively connected with the port 35 and the air intake port of the compressor. The opening and closing of the second expansion valve 6 controls the flow rate of the refrigerant from the exhaust port of the compressor to the air intake port of the condenser and the compressor. When it is closed, the refrigerant flows to the inlet of the condenser 3; when it is opened, a part of the refrigerant flows to the inlet of the condenser, and the other part flows to the air intake port of the compressor. The port 32 of the refrigerant channel of the condenser 3 is connected to the end A having the first channel. The ports 33 and 34 of the coolant channel of the condenser 3 are respectively connected to one end of the first coolant inlet HA and one end of the first coolant outlet HE. The condenser 3 can be fixedly connected to the flow channel plate 1 through a plurality of bolt holes 361 of its mounting base 36.

[0050] Figure 6 This is a schematic diagram of the structure of a regenerator of an embodiment of the utility model. The regenerator 4 also has two channels, but the difference is that they are both refrigerant channels. The two ends of one refrigerant channel of the regenerator 4 are ports 41 and 42, which are respectively connected to the A' end of the first channel and the B end of the second channel. The two ends of the other refrigerant channel of the regenerator 4 are ports 43 and 44, which are respectively connected to the C' end of the third channel and the air intake of the compressor 2. Preferably, port 44 can be provided with a bypass port 441, and the bypass port 441 can be connected to one end of the channel of the fourth channel DD' connected to the air intake of the compressor. It should be noted that the gap H4 is provided at the flow channel plate 1 where the regenerator 4 is provided, so that the port 44 of the refrigerant channel of the regenerator 4 can pass through the gap H4 and be directly connected to the air intake of the compressor 2. Similarly, the regenerator 4 can be fixedly connected to the flow channel plate 1 through multiple bolt holes of its mounting base.

[0051] In the thermal management integrated module of the utility model, a regenerator is used instead of a liquid storage device. On the one hand, the subcooling degree before the valve can be increased, the cooling capacity can be improved, and the problem of low heat exchange efficiency of the secondary circuit can be improved, thereby reducing the required speed or displacement of the compressor and increasing the efficiency of the thermal management integrated module. On the other hand, by increasing the length of the subcooling section in the regenerator, the functions of storing excess refrigerant and dealing with minor leaks can be realized.

[0052] In order to reduce the vibration between the condenser and the compressor, and between the regenerator and the compressor, a vibration reduction unit may be provided at the connection between the condenser 3 and the exhaust port of the compressor 2, and at the connection between the regenerator 4 and the air intake port of the compressor. Taking the vibration reduction unit at the connection between the condenser 3 and the exhaust port of the compressor 2 as an example, the vibration reduction unit may include a bellows 39 and a vibration isolation ring 38 sleeved on the bellows 39. The bellows 39 may be a metal bellows, and the vibration isolation ring 38 may be a material that can absorb vibration, such as rubber and polyurethane. Furthermore, a pressure plate 37 may be provided at the connection, one end of the pressure plate is welded to the bellows 39, and a bolt hole 371 is provided at the other end, and the pressure plate is connected to the exhaust port of the compressor 2 through the bolt hole 371 and the bolts, see Figure 5 . The above structure can effectively reduce the transmission of compressor vibration to the whole vehicle, effectively reduce the overall vibration of the thermal management integrated module, and can also be compactly arranged. Using metal bellows instead of existing rubber tubes can make the pipeline shorter, and can also deal with the problem of natural refrigerants such as R290 with small molecules and easy leakage. The connection between the regenerator 4 and the air intake of the compressor can also adopt a vibration reduction unit of similar structure, which will not be elaborated here.

[0053] Figure 7 This is a schematic diagram of the structure of an evaporator of an embodiment of the utility model. The evaporator 5 has two channels, one of which is a refrigerant channel and the other is a coolant channel. The two ends of the refrigerant channel of the evaporator 5 are ports 51 and 52, which are respectively connected to the B' end of the second channel and the C' end of the third channel. The two ends of the coolant channel of the evaporator 5 are ports 53 and 54, which are respectively connected to one end of the second coolant inlet CA and one end of the second coolant outlet CE. The evaporator 5 can also be fixedly connected to the flow channel plate 1 through multiple bolt holes on its mounting base.

[0054] In the above structure, the exhaust port of the compressor 2, the refrigerant channel of the condenser 3, the first channel AA', a refrigerant channel of the regenerator 4, the second channel BB', the refrigerant channel of the evaporator 5, the third channel CC', another refrigerant channel of the regenerator 4 and the air intake port of the compressor 2 are connected in sequence to form a refrigerant circuit. The flow directions of the refrigerants in the first channel AA', the second channel BB' and the third channel CC' are as follows: Figure 4 As shown by the dotted arrows. The first coolant exchanges heat with the refrigerant through the condenser 3, and the second coolant exchanges heat with the refrigerant through the evaporator 5.

[0055] In the thermal management integrated module of the utility model, each component is connected through the built-in channel of the flow channel plate, eliminating the traditional pipeline, reducing the refrigerant charge and reducing the risk of refrigerant leakage. At the same time, the integration of the thermal management integrated module is improved, and the compact thermal management integrated module has more advantages in assembly. When it is applied to a whole vehicle, such as an electric car, the whole vehicle can obtain a cold / hot refrigerant of a certain temperature, and can exchange heat with different cold sources / heat sources flowing into the vehicle by switching the water channel.

[0056] Figure 8 For the utility model Figure 1 The connection diagram of the thermal management integrated module of the embodiment, wherein the compressor compresses the refrigerant gas and sequentially enters the port 31 of the condenser 3 from the exhaust port of the compressor 2, enters the port 41 of the regenerator 4 through the port 32 of the condenser 3 after heat exchange in the condenser 3, enters the evaporator 5 after the port 42 of the regenerator 4 and the throttling of the first expansion valve 7 after heat exchange, and the refrigerant channel of the evaporator 5 exchanges heat with the refrigerant channel, and then enters the regenerator 4 from the port 52 of the evaporator 5, and enters the air intake port of the compressor 2 after heat exchange with the fluid after the condenser 3 to repeat the cycle. In the ultra-low temperature heating and heating startup stages, the second expansion valve 6 can be adjusted so that part of the gas discharged from the exhaust port of the compressor 2 flows directly from the second expansion valve 6 to the air intake port of the compressor 2 to widen the lowest heating temperature of the system.

[0057] In some embodiments, the thermal management integrated module may also include a first sensor assembly C1 disposed in the third channel CC', the first sensor assembly including a first temperature sensor and a first pressure sensor. Similarly, the thermal management integrated module also includes a second sensor assembly C2 disposed in the first channel AA', the second sensor assembly including a second temperature sensor and a second pressure sensor. Further, the thermal management integrated module also includes a third sensor assembly C3 disposed at the compressor intake port, the third sensor assembly including a third temperature sensor and a third pressure sensor. Further, the thermal management integrated module may also include a fourth temperature sensor disposed at the first refrigerant outlet HE, and / or the thermal management integrated module also includes a fifth temperature sensor disposed at the second refrigerant outlet CE.

[0058] In some other embodiments, the second expansion valve 6 and the first expansion valve 7 can be electronic expansion valves. In this case, the thermal management integrated module also includes a control unit, which is configured to control the state of the second expansion valve and the state of the first expansion valve. For example, the thermal management integrated module can monitor the first sensor component C1, the second sensor component C2, the fourth temperature sensor and the fifth temperature sensor. The control unit is configured to collect and analyze the above data, and control the opening of the first expansion valve 7 and the second expansion valve 6 according to the data collected by the above sensors, so as to control the flow rate of the refrigerant from the exhaust port of the compressor to the condenser and the suction port of the compressor, and the flow rate of the refrigerant from the regenerator 4 to the evaporator 5.

[0059] The structure of the thermal management integrated module is further described below using a control method of the thermal management integrated module. Fig. 9 This is a flow chart of a control method of a thermal management integrated module according to an embodiment of the present invention. Specifically, the control method includes the following steps:

[0060] S10: monitoring the ambient temperature of the thermal management integrated module and the air pressure at the air inlet of the compressor. The ambient temperature can be obtained by reading the temperature of the use environment, and the air pressure at the air inlet of the compressor can be obtained by collecting data from the third pressure sensor.

[0061] S21: determining whether the ambient temperature is less than a threshold temperature and S22: determining whether the air pressure at the compressor suction port is less than a threshold pressure;

[0062] If the ambient temperature is lower than the threshold temperature and the air pressure at the air intake port of the compressor is lower than the threshold pressure, then S31: the control unit controls the second expansion valve to be in an open state and adjusts the opening degree through the temperature and pressure signal. The threshold temperature and the threshold pressure can be set according to the specific use scenario of the compressor, such as the threshold pressure can be -15° or -20°, the threshold pressure can be 0.15 MPa, etc.

[0063] If the ambient temperature is not less than the threshold temperature or the air pressure at the compressor suction port is not less than the threshold pressure, then S32: the control unit controls the second expansion valve to be in a closed state. In this case, the opening of the first electronic expansion valve can also be controlled according to the suction superheat of the compressor, and the compressor speed can be controlled according to the outlet water temperature of the condenser and evaporator.

[0064] The utility model also provides an electric vehicle, comprising the thermal management integrated module. The thermal management integrated module also includes a control unit and a second expansion valve and / or a first expansion valve; the first expansion valve is arranged in the second channel. The flow channel plate is also provided with a fourth channel; the fourth channel connects the exhaust port of the compressor, the condenser and the air intake port of the compressor; the second expansion valve is arranged in the fourth channel, and the second expansion valve controls the flow rate of the refrigerant from the exhaust port of the compressor to the condenser and the air intake port of the compressor respectively; the control unit is configured to control the state of the second expansion valve and the state of the first expansion valve; the control unit is integrated into the controller of the compressor, and after the integrated control, the compressor controller can be regarded as the thermal management integrated module controller. The weak current end of the controller uses a multi-pin plug-in to realize sensor signal acquisition. The vehicle controller of the electric vehicle is the upper computer. At this time, the drive of the electronic expansion valve communicates with the signal of the vehicle, see Fig.10 . Integrating the control unit of the thermal management integrated module into the compressor controller can realize the optimization of the refrigerant circuit control while realizing the compressor control. At this time, the thermal management integrated module is installed in the vehicle as a relatively independent component, and the high-voltage and low-voltage power lines are input. The vehicle host computer sends the required cold water temperature / hot water temperature or other parameter targets through the communication bus. The compressor can control the speed and other parameters according to the pressure and temperature of each point to realize the functions of cooling and heating, thereby realizing the optimization of system efficiency and safety.

For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present application.
