Abstract
Description
Technical Field
[0001] The present application relates to the field of vehicle thermal management technology, and in particular to a thermal management integrated module and a vehicle. Background Art
[0002] With the surge of electric vehicles in the new energy vehicle industry, electric vehicle thermal management systems have become unprecedentedly complex and important. Traditional thermal management system designs tend to optimize each component individually without fully considering an integrated layout. This results in multiple components within the thermal management system, such as water pumps, valves, and expansion tanks, being dispersed throughout the engine compartment, creating a complex piping layout that takes up a significant amount of space. Furthermore, these dispersed components and complex piping layouts not only increase the difficulty of initial assembly, but also lead to high flow resistance and severe heat loss due to the complex piping layout and multiple connection points.
[0003] To address this issue, existing technologies propose integrating multiple components within a thermal management system into a single unit. This reduces the space required for the thermal management system, optimizes piping layout, and achieves vehicle lightweighting. However, existing integrated module technologies still face several technical bottlenecks. While some component integration has been achieved to some extent, most utilize multiple, dispersed valves for control, resulting in complex wiring and piping connections. This leads to insufficient low-temperature heating capacity and low high-temperature cooling efficiency. Summary of the Invention

[0050] like Figures 1 to 4 、 Figure 6 and Figure 7 as well as Figure 9As shown, this embodiment provides a thermal management integrated module for connecting to the refrigerant circulation circuit 100 and the coolant circulation circuit 200, and the thermal management integrated module includes: an agent side flow channel plate 1, a water side flow channel plate 2, a first heat exchanger 3 and a second heat exchanger 4, the agent side flow channel plate 1 has a plurality of refrigerant channels 11 for connecting to the refrigerant circulation circuit 100 and a plurality of agent side flow channel interfaces 12 for connecting the refrigerant channels 11, wherein some of the agent side flow channel interfaces 12 are connected to the agent side thermal management component 13 installed on the agent side flow channel plate 1, and the remaining agent side flow channel interfaces 12 is used to connect the agent side heat exchange component 14 of the refrigerant circulation loop 100 to the outside; the water side flow channel plate 2 is fixedly connected to the agent side flow channel plate 1 with the plate surface facing each other, and has a plurality of coolant channels 21 for accessing the coolant circulation loop 200 and a plurality of water side flow channel interfaces 22 for connecting the coolant channels 21, wherein some of the water side flow channel interfaces 22 are connected to the water side thermal management component 23 installed on the water side flow channel plate 2, and the remaining water side flow channel interfaces 22 are used to connect to the water side heat exchange component 24 of the coolant circulation loop 200; in this way, by being connected as one The agent side flow channel plate 1 and the water side flow channel plate 2 can integrate a variety of thermal management components and connect a variety of heat exchange components to the outside, thereby greatly reducing the installation space requirements of the vehicle thermal management system and its components in the engine compartment, making the product layout more compact, and reducing the flow resistance and heat loss of the refrigerant and coolant in the thermal management system; at the same time, the first heat exchanger 3 can be fixed to one side of the agent side flow channel plate 1 by bolts, and the first heat exchanger 3 has an agent side section 31 and a water side section 32, wherein the agent side section 31 is connected to the refrigerant channel 11, and the water side section 32 is connected to the coolant channel 21, so that the refrigerant flowing through the agent The refrigerant in the side section 31 exchanges heat with the coolant flowing through the water side section 32. Similarly, the second heat exchanger 4 can be fixed to one side of the agent side flow channel plate 1 by bolts. The second heat exchanger 4 has a subcooling section 41 and a superheating section 42. The subcooling section 41 is connected to the refrigerant channel 11 and is located on the inlet side of the agent side section 31 in the refrigerant circulation circuit 100. The superheating section 42 is connected to the refrigerant channel 11 and is located on the outlet side of the agent side heat exchange component 14 in the refrigerant circulation circuit 100, so that the refrigerant flowing through the hot section 42 and the refrigerant flowing through the cold section 41 can exchange heat with each other. In this way, the second heat exchanger 4 can be used to perform secondary heat exchange on the refrigerant at the front end of the first heat exchanger 3, thereby improving the heat exchange efficiency of the refrigerant flowing through the first heat exchanger 3 and achieving the purpose of further improving the heat exchange effect between the refrigerant and the coolant in the first heat exchanger 3.
[0051] For example, if Figures 1 to 4 as well as Figure 9 As shown, the agent-side thermal management component 13 includes a first electronic expansion valve 131, and the plurality of refrigerant channels 11 include a first agent-side flow channel 111, a second agent-side flow channel 112, a third agent-side flow channel 113, and a fourth agent-side flow channel 114; wherein:
[0052] The first agent-side flow channel 111 has three agent-side flow channel interfaces 12, two of which are connected to the second end of the subcooling section 41 and the first end of the first electronic expansion valve 131, respectively. The third agent-side flow channel interface 12 is used as the first agent-side interface 121 to connect to the inlet end of the agent-side heat exchange component 14.
[0053] The second agent side flow channel 112 has two agent side flow channel interfaces 12 , and the two agent side flow channel interfaces 12 are respectively connected to the second end of the first electronic expansion valve 131 and the first end of the agent side section 31 ;
[0054] The third agent-side flow channel 113 has two agent-side flow channel interfaces 12, one of which is connected to the first end of the superheating section 42, and the other agent-side flow channel interface 12 is used as a second agent-side interface 122 to connect to the outlet end of the agent-side heat exchange component 14.
[0055] The fourth agent side flow channel 114 has two agent side flow channel interfaces 12, which are respectively connected to the second end of the superheating section 42 and the second end of the agent side section 31; the fourth agent side flow channel 114 or the superheating section 42 also has a third agent side interface 123 for externally connecting to the inlet end of the compressor 141 of the agent side heat exchange component 14.
[0056] In this way, the refrigerant circulating in the refrigerant circulation loop 100 passes through the subcooling section 41 of the second heat exchanger 4 and flows into the first agent side flow channel 111 from the second end of the subcooling section 41, and then is divided in the first agent side flow channel 111, wherein a part of the refrigerant enters the inlet end of the agent side heat exchange component 14 through the first agent side interface 121, and after the action of the agent side heat exchange component 14, enters the third agent side flow channel 113 through the second agent side interface 122, and flows into the superheating section 42 from the first end of the superheating section 42. At this time, the refrigerant flowing through the hot section 42 exchanges heat with the refrigerant flowing through the cold section 41. The refrigerant flowing through the cold section 41 undergoes secondary heat exchange; the other portion of refrigerant (which has undergone secondary heat exchange) diverted from the first agent-side flow channel 111 enters the second agent-side flow channel 112 through the first electronic expansion valve 131, and enters the agent-side section 31 of the first heat exchanger 3 from the second agent-side flow channel 112, and exchanges heat with the coolant flowing through the water-side section 32. Subsequently, the other portion of refrigerant flows into the fourth agent-side flow channel 114, merges with the refrigerant flowing through the hot section 42, and is sucked into the refrigerant circulation circuit 100 by the compressor 141 from the third agent-side interface 123 to continue participating in the refrigerant cycle. Under the action of the second heat exchanger 4, the heat exchange efficiency of the refrigerant flowing through the first heat exchanger 3 is effectively improved. At the same time, through the integrated connection of the pipes and components of the agent-side flow channel plate 1, the length of the refrigerant flow path between the second heat exchanger 4 and the first heat exchanger 3 is greatly shortened, which can significantly improve the heat exchange effect between the refrigerant and the coolant in the first heat exchanger 3.
[0057] It can be understood that a first electronic expansion valve mounting hole 151 can be set between the first agent side flow channel 111 and the second agent side flow channel 112, and the first electronic expansion valve mounting hole 151 can be used to connect the agent side flow channel interface 12 between the first agent side flow channel 111 and the second agent side flow channel 112, and then the first electronic expansion valve 131 can be embedded in the first electronic expansion valve mounting hole 151 in a plug-in manner and fixed to the agent side flow channel plate 1 by bolts to realize the connection of the first electronic expansion valve 131 between the first agent side flow channel 111 and the second agent side flow channel 112.
[0058] Preferably, the third agent-side interface 123 is disposed near the second end of the superheating section 42 to prevent the refrigerant flowing through the agent-side section 31, after exchanging heat with the coolant, from entering the superheating section 42 and affecting the heat exchange efficiency between the superheating section 42 and the subcooling section 41. Furthermore, the third agent-side interface 123 can be disposed directly on the second cooler near the second end of the superheating section 42, thereby reducing the number of interfaces disposed on the agent-side flow channel plate 1 and improving the sealing performance and morphological modulus of the agent-side flow channel plate 1.
[0059] Preferably, if Figures 1 to 4 As shown, the first agent side flow channel 111, the second agent side flow channel 112, the third agent side flow channel 113 and the fourth agent side flow channel 114 are distributed at intervals on the agent side flow channel plate 1, and hollow areas are formed between the flow channels, which can clearly distinguish the cold and hot flow channels and achieve the purpose of avoiding heat conduction. Furthermore, in addition to the bolt connection points and necessary support frames for relative connection and fixation between the water-side flow channel plate 2 and the agent-side flow channel plate 1, hollow areas are also formed on the relative inner sides of the water-side flow channel plate 2 and the agent-side flow channel plate 1 to achieve weight reduction and avoid heat cross-contamination between the hot and cold flow channels; at the same time, the agent-side thermal management component 13 and the water-side thermal management component 23 are respectively arranged on the relative outer sides of the agent-side flow channel plate 1 and the water-side flow channel plate 2, and a first notch 154 and a second notch 155 are formed at the position of the agent-side flow channel plate 1 corresponding to the first heat exchanger 3. The two water-side flow channel interfaces 22 of the water-side flow channel plate 2 for connecting the water-side section 32 of the first heat exchanger 3 are arranged on the side of the water-side flow channel plate 2 close to the agent-side flow channel plate 1, and are connected to the two ends of the water-side section 32 of the first heat exchanger 3 through the first notch 154 and the second notch 155, thereby reducing the space occupied by the thermal management integrated module, making the product layout more compact, and reducing the flow resistance and heat transfer loss of the refrigerant and coolant in the thermal management integrated module.
[0060] In some embodiments, as Figure 9 and Figure 10As shown, the agent-side heat exchange assembly 14 includes at least one internal evaporator group 142, and the first agent-side interface 121 and the second agent-side interface 122 are externally connected to the inlet and outlet of the at least one internal evaporator group 142, respectively. Thus, after absorbing heat in the internal evaporator group 142, the refrigerant vaporizes into a low-temperature, low-pressure gaseous refrigerant and enters the superheating section 42 of the second heat exchanger 4, exchanging heat with the refrigerant flowing through the subcooling section 41 of the second heat exchanger 4. This increases the subcooling of the refrigerant flowing through the subcooling section 41 of the second heat exchanger 4, thereby improving the heat exchange effect between the refrigerant and the coolant in the water-side section 32 when it subsequently flows through the agent-side section 31 of the first heat exchanger 3.
[0061] For example, if Figure 9 and Figure 10 As shown, the internal evaporator group 142 includes an evaporator and an electronic expansion valve arranged at the inlet end of the evaporator. The electronic expansion valve is recorded as the third electronic expansion valve 1421. After throttling and expanding through the third electronic expansion valve 1421, the refrigerant enters the evaporator and evaporates into a low-temperature, low-pressure gas. After that, it enters the third agent-side flow channel 113 and then enters the superheating section 42 of the second heat exchanger 4 to participate in heat exchange with the subcooling section 41. The first heat exchanger 3 can be a battery cooler chiller, which mainly consists of a refrigerant inlet and outlet pipe, namely the agent-side section 31, a coolant inlet and outlet pipe, namely the water-side section 32, a heat exchanger body and an external evaporator (not shown). After throttling and expanding through the first electronic expansion valve 131, the refrigerant enters the external evaporator and evaporates into a low-temperature, low-pressure gas. After that, it enters the fourth agent-side flow channel 114 and merges with the low-temperature, low-pressure gaseous refrigerant flowing through the superheating section 42. Then, it is sucked into the refrigerant circulation circuit 100 by the compressor 141 through the third agent-side interface 123 to continue participating in the refrigerant circulation. In this way, the microprocessor can control the opening and closing of the third electronic expansion valve 1421 and the first electronic expansion valve 131, and can achieve precise adjustment of the refrigerant flow rate.
[0062] It is understandable that the number of internal evaporator groups 142 connected to the thermal management integrated module can be set according to the project configuration, such as Figure 9 and Figure 10 As shown, in other embodiments, a rear HVAC air-cooled evaporator group 143 can be added in parallel with the above-mentioned internal evaporator group 142, and the first agent side interface 121 and the second agent side interface 122 are respectively connected to the common inlet and outlet ends of the air-cooled evaporator group 143 and the above-mentioned internal evaporator group 142. In this way, one of the air-cooled evaporator group 143 and the above-mentioned internal evaporator group 142 can be selected for use according to needs, or one of the groups can be used as a redundancy design to ensure function implementation, and the heat exchange efficiency of the refrigerant flowing through the hot section 42 can also be further improved through the joint action of the air-cooled evaporator group 143 and the above-mentioned internal evaporator group 142.
[0063] It can also be understood that by opening and closing the electronic expansion valve of the internal evaporator group 142, namely the third electronic expansion valve 1421, the electronic expansion valve of the air-cooled evaporator group 143 (recorded as the fourth electronic expansion valve 1431) and the first electronic expansion valve 131, the flow direction of the refrigerant can be controlled to meet the needs of the refrigeration cycle or the heat pump cycle.
[0064] In some embodiments, as Figures 1 to 5 as well as Figures 9 to 11 As shown, the agent-side thermal management component 13 further includes a second electronic expansion valve 132, a one-way valve 133, and a four-way valve 134. The agent-side heat exchange component 14 further includes an internal condenser 144 and an external condenser 145. In the refrigerant circulation loop 100, the outlet end of the compressor 141 is connected to the inlet end of the internal condenser 144 to transport the compressed high-temperature and high-pressure gaseous refrigerant to the internal condenser 144 to condense it into a high-temperature and high-pressure liquid refrigerant; the refrigerant channel 11 further includes a fifth agent-side flow channel 115, a sixth agent-side flow channel 116, a seventh agent-side flow channel 117, and an eighth agent-side flow channel 118; wherein:
[0065] The fifth agent-side flow channel 115 has two agent-side flow channel interfaces 12 , one of which is used as the outlet end of the fourth agent-side interface 124 connected to the internal condenser 144 , and the other agent-side flow channel interface 12 is connected to the first valve port 1341 of the four-way valve 134 .
[0066] The sixth agent-side flow channel 116 has two agent-side flow channel interfaces 12 , one of which is used as the inlet end of the fifth agent-side interface 125 connected to the external condenser 145 , and the other agent-side flow channel interface 12 is connected to the second valve port 1342 of the four-way valve 134 .
[0067] The seventh agent-side flow channel 117 has three agent-side flow channel interfaces 12, two of which are connected to the second end of the second electronic expansion valve 132 and the inlet end of the one-way valve 133, respectively. The third agent-side flow channel interface 12 is used as the outlet end of the sixth agent-side interface 126 connected to the external condenser 145.
[0068] The eighth agent-side flow channel 118 has three agent-side flow channel interfaces 12, two of which are connected to the first end of the subcooling section 41 and the outlet end of the one-way valve 133, respectively. The third agent-side flow channel interface 12 serves as the seventh agent-side interface 127 and is connected to the fourth valve port 1344 of the four-way valve 134.
[0069] The first agent side flow channel 111 also has an eighth agent side interface 128, which is connected to the first end of the second electronic expansion valve 132; the fourth agent side flow channel 114 also has a ninth agent side interface 129, which is connected to the third valve port 1343 of the four-way valve 134; the four-way valve 134 has a cooling mode and a heat pump mode, and is configured to be switchable between the cooling mode and the heat pump mode; in the cooling mode, the first valve port 1341 is connected to the second valve port 1342, and the third valve port 1343 is connected to the fourth valve port 1344; in the heat pump mode, the first valve port 1341 is connected to the fourth valve port 1344, and the second valve port 1342 is connected to the third valve port 1343. In this way, the refrigerant flow in the refrigerant circulation circuit 100 can be controlled by opening and closing the four-way valve 134 in conjunction with the electronic expansion valve, thereby realizing the switching between the cooling cycle and the heat pump cycle and the multi-mode control requirements.
[0070] In the cooling mode, the first electronic expansion valve 131 and the third electronic expansion valve 1421 can be opened, and the second electronic expansion valve 132 can be closed. In this way, the refrigerant sucked into the refrigerant circulation circuit 100 by the compressor 141 and continuing to participate in the circulation passes through the internal condenser 144, the fourth agent side interface 124, the fifth agent side flow channel 115, the first valve port 1341, the second valve port 1342, the sixth agent side flow channel 116, the fifth agent side interface 125, the external condenser 145 and the sixth agent side interface 126 and enters the seventh agent side flow channel 117. At this time, the high-temperature and high-pressure liquid refrigerant flows into the eighth agent side flow channel 118 through the inlet end of the one-way valve 133, and then enters the subcooling section 41 from the first end of the subcooling section 41 to participate in the heat exchange with the superheating section 42, thereby improving the subcooling degree of the refrigerant flowing out of the second end of the subcooling section 41, thereby achieving the purpose of improving the heat exchange effect between the refrigerant and the coolant in the first heat exchanger 3.
[0071] It can be understood that in the cooling mode, the third electronic expansion valve 1421 can also be opened, and the first electronic expansion valve 131 and the second electronic expansion valve 132 can be closed. The first heat exchanger 3 is not used, and only the second heat exchanger 4 is used to increase the supercooling degree of the refrigerant flowing out of the second end of the supercooling section 41 to meet the separate cooling needs of the passenger compartment.
[0072] In the heat pump mode, the third electronic expansion valve 1421 can be closed, and the first electronic expansion valve 131 and the second electronic expansion valve 132 can be opened. In this way, the refrigerant sucked into the refrigerant circulation loop 100 by the compressor 141 and continuing to participate in the circulation passes through the internal condenser 144, the fourth agent side interface 124, the fifth agent side flow channel 115, the first valve port 1341 and the fourth valve port 1344 in sequence to enter the eighth agent side flow channel 118, and then passes through the subcooling section 41 and enters the first agent side flow channel 111, and is diverted in the first agent side flow channel 111, and a part of the refrigerant passes through the first electronic expansion valve 131 into the second agent side flow channel 112 to participate in the heat exchange between the first heat exchanger 3 agent side section 31 and the water side section 32 The waste heat of the coolant in the water side section 32 is used to heat the refrigerant in the agent side section 31; another part of the refrigerant enters the second electronic expansion valve 132 through the eighth agent side interface 128 for throttling expansion and then enters the external condenser 145 (used as an evaporator at this moment), and is evaporated into a low-temperature and low-pressure gas by the external condenser 145, and then enters the sixth agent side flow channel 116 through the fifth agent side interface 125, and then passes through the second valve port 1342 and the third valve port 1343 in sequence, and then enters the fourth agent side flow channel 114 from the ninth agent side interface 129, and merges with the refrigerant flowing through the agent side section 31, and is sucked into the refrigerant circulation circuit 100 by the compressor 141 from the third agent side interface 123 to continue to participate in the refrigerant heat pump cycle.
[0073] It can be understood that, in the heat pump mode, the first electronic expansion valve 131 and the third electronic expansion valve 1421 can also be closed, and the second electronic expansion valve 132 can be opened. In this way, the refrigerant sucked into the refrigerant circulation circuit 100 by the compressor 141 and continuing to participate in the circulation passes through the internal condenser 144, the fourth agent side interface 124, the fifth agent side flow channel 115, the first valve port 1341 and the fourth valve port 1344 in sequence to enter the eighth agent side flow channel 118, and then passes through the subcooling section 41 and enters the first agent side flow channel 111. It then flows into the second electronic expansion valve 132 through the eighth agent side interface 128, is throttled and expanded, and then enters the external condenser 145. It is evaporated into a low-temperature and low-pressure gas by the external condenser 145, and then enters the sixth agent side flow channel 116 through the fifth agent side interface 125. It then passes through the second valve port 1342 and the third valve port 1343 in sequence, and then enters the fourth agent side flow channel 114 from the ninth agent side interface 129, and is sucked into the refrigerant circulation circuit 100 by the compressor 141 from the third agent side interface 123 to continue participating in the refrigerant heat pump cycle.
[0074] It can also be understood that a second electronic expansion valve mounting hole 152 can be set between the first agent side flow channel 111 and the seventh agent side flow channel 117, and the second electronic expansion valve mounting hole 152 can be used to connect the agent side flow channel interface 12 between the first agent side flow channel 111 and the seventh agent side flow channel 117, and then the second electronic expansion valve 132 can be embedded in the second electronic expansion valve mounting hole 152 in a plug-in manner and fixed to the agent side flow channel plate 1 by bolts to realize the connection of the second electronic expansion valve 132 between the first agent side flow channel 111 and the seventh agent side flow channel 117. Similarly, by setting a one-way valve mounting hole 153 between the seventh agent side flow channel 117 and the eighth agent side flow channel 118, using the one-way valve mounting hole 153 to connect the agent side flow channel interface 12 between the seventh agent side flow channel 117 and the eighth agent side flow channel 118, and then inserting the one-way valve 133 into the one-way valve mounting hole 153 in a plug-in manner to fix it on the agent side flow channel plate 1, the connection of the one-way valve 133 between the seventh agent side flow channel 117 and the eighth agent side flow channel 118 can be achieved.
[0075] In some embodiments, as Figures 1 to 4 as well as Figure 9 As shown, the agent-side thermal management assembly 13 further includes a liquid storage and drying bottle 135, and the refrigerant channel 11 further includes a ninth agent-side flow channel 119. The agent-side flow channel interface 12 of the eighth agent-side flow channel 118, which is used to connect to the first end of the subcooling section 41, is connected to the first end of the liquid storage and drying bottle 135. The ninth agent-side flow channel 119 has two agent-side flow channel interfaces 12, which are respectively connected to the second end of the liquid storage and drying bottle 135 and the first end of the subcooling section 41. In this way, the liquid storage and drying bottle 135 can be used to filter, dry, store, and supply liquid refrigerant, thereby compensating for and adjusting the surplus and deficit of liquid refrigerant when operating conditions change.

[0084] Seven-way valve 233 has multiple control modes and is configured to switch between them. In each control mode, one valve port of seven-way valve 233 is blocked, while the remaining six valve ports are connected in pairs. Seven-way valve 233 can switch the connection relationship between the valve ports by switching the control mode. In this way, seven-way valve 233 can control the direction of coolant in coolant circulation loop 200, further providing multi-mode control of the water side when the refrigerant is in cooling mode or heat pump mode to meet diverse needs.

[0090] In some embodiments, as Figure 15 and Figure 16 As shown, the control mode also includes a fourth mode and a fifth mode, and the seven-way valve 233 is configured to be able to switch to the fourth mode or the fifth mode, wherein:
[0091] In the fourth mode, valve port three 2333 is in a blocked state, valve port one 2331 is connected to valve port two 2332, valve port four 2334 is connected to valve port six 2336, and valve port five 2335 is connected to valve port seven 2337; at this time, the low-temperature radiator 243 is short-circuited and does not work, the water-heating PTC heater 241 and the battery pack heat exchange pipeline 242 are connected in series to form an independent circulation loop, and the first heat exchanger 3 and the drive system heat exchange pipeline 244 are connected in series to form an independent circulation loop; in this way, when the seven-way valve 233 is in the fourth mode and the four-way valve 134 is in the cooling mode, it can meet the needs of passenger compartment cooling, battery pack independent heat dissipation, and refrigerant circulation circuit 100 assisting drive system heat dissipation; when the seven-way valve 233 is in the fourth mode and the four-way valve 134 is in the heat pump mode, it can meet the needs of passenger compartment heating, water-heating PTC heater 241 independently heating the battery pack, and drive system waste heat assisting passenger compartment heating.

[0093] In some embodiments, as Figure 4 、 Figures 6 to 9 As shown, the water-side thermal management component 23 further includes a three-way valve 234, which is provided in the fourth water-side flow channel 214 and has a main valve port 2341 and two auxiliary valve ports 2342; the plurality of coolant channels 21 further include an eighth water-side flow channel 218 and a ninth water-side flow channel 219, wherein:
[0094] One of the water-side flow channel interfaces 22 of the fourth water-side flow channel 214 is connected to the sixth valve port 2336 , and the other water-side flow channel interface 22 is connected to the main valve port 2341 of the three-way valve 234 ;

The other port 22 serves as the second water channel port 222, externally connected to the water outlet of the battery pack heat exchange pipeline 242. Thus, when the water-heating PTC heater 241 is turned on, the coolant heated by the water-heating PTC heater 241 is directed into the eighth water channel 218 and directly participates in the coolant circulation via the sixth valve port 2336, thus enabling the use of the water-heating PTC heater 241 alone to heat the passenger compartment.
[0097] Preferably, the three-way valve 234 is a variable-section three-way valve, capable of adjusting the flow ratio of the two auxiliary valve ports 2342 by controlling the relative openings of the two auxiliary valve ports 2342.
