Liquid storage tank, air conditioning device and vehicle

Abstract

The utility model discloses a liquid storage tank. The liquid storage tank comprises a tank body and a valve. A liquid storage cavity, a first liquid outlet and a second liquid outlet are formed in the tank body. When the liquid storage tank is in a working state, the second liquid outlet is higher than the first liquid outlet. The valve is arranged at the first liquid outlet. Therefore, when the automobile is in a high-temperature environment, the valve can be closed, and the liquid refrigerant can only flow out of the liquid storage tank through the second liquid outlet under the pressure in the liquid storage tank. And under the condition that the automobile is in a low-temperature environment, the valve is opened, and the liquid refrigerant flows out of the liquid storage tank through the first liquid outlet under the pressure in the liquid storage tank. Due to the fact that the second liquid outlet is higher than the first liquid outlet, the liquid refrigerant is more difficult to flow out of the liquid storage tank under the condition that the automobile is in a high-temperature environment, the liquid storage tank can store more refrigerant, on the contrary, the liquid refrigerant is easier to flow out of the liquid storage tank under the condition that the automobile is in a low-temperature environment, and the liquid storage amount of the liquid storage tank can be adjusted.

Description

Technical Field

[0001] The present application relates to the technical field of automobile air conditioners, and more specifically, to a liquid storage tank, an air conditioning device and a vehicle. Background Art

[0002] In the prior art, the refrigerant in the automobile air conditioner that does not participate in the heat exchange is stored in a liquid storage tank in a liquid state. When the automobile is in a high temperature environment, the automobile air conditioner needs to be cooled, and only a small amount of refrigerant is required to participate in the heat exchange. Therefore, it is hoped that the refrigerant entering the liquid storage tank will flow out of the liquid storage tank less, so that more liquid refrigerant can be stored in the liquid storage tank. When the automobile is in a low temperature environment, the automobile air conditioner needs to be heated, and more refrigerant is required to participate in the heat exchange. Therefore, it is hoped that more refrigerant will flow out of the liquid storage tank, so that less liquid refrigerant can be stored in the liquid storage tank. However, the liquid storage tank in the prior art cannot adjust the liquid storage amount under different ambient temperatures. Utility Model Content

[0003] Embodiments of the present application provide a liquid storage tank, an air conditioning device, and a vehicle.

[0004] The liquid storage tank of the embodiment of the present application includes a tank body and a valve, the tank body is formed with a liquid storage cavity, a first liquid outlet and a second liquid outlet, when the liquid storage tank is in working state, the second liquid outlet is higher than the first liquid outlet; the valve is arranged at the first liquid outlet.

[0005] In this way, when the liquid storage tank is used in automobile air conditioning, when the car is in a high temperature environment, the valve can be closed, and the liquid refrigerant can only flow out of the liquid storage tank through the second liquid outlet under the pressure in the liquid storage tank. When the car is in a low temperature environment, the valve is opened, and the liquid refrigerant flows out of the liquid storage tank through the first liquid outlet under the pressure in the liquid storage tank. Since the second liquid outlet is higher than the first liquid outlet, it is more difficult for the liquid refrigerant to flow out of the liquid storage tank when the car is in a high temperature environment than when the car is in a low temperature environment. Therefore, the liquid storage tank can store more refrigerant, and vice versa.

[0006] In some embodiments, the tank body includes a tank bottom. When the liquid storage tank is in working state, the tank bottom is located below the liquid storage cavity. A flow channel is formed on the tank bottom. The flow channel passes through the tank bottom and connects to the liquid storage cavity to form the first liquid outlet.

[0007] In this way, by arranging the first liquid outlet on the upper surface of the tank bottom, that is, the bottom surface of the liquid storage cavity, that is, the first liquid outlet is located at the very bottom of the liquid storage cavity, and a connection between the liquid storage cavity and the outside of the tank body is formed at the bottom of the tank, it is possible to open the valve when the car is in a low temperature environment, and the liquid refrigerant can more easily flow out of the liquid storage tank through the first liquid outlet under the pressure in the liquid storage tank.

[0008] In some embodiments, the flow channel is formed with a first flow segment, a second flow segment and a third flow segment. When the liquid storage tank is in working state, the first flow segment extends downward from the first liquid outlet, the second flow segment extends basically horizontally from the side of the tank bottom and is connected with the first flow segment, the third flow segment extends upward from the bottom surface of the tank bottom and is connected with the second flow segment, and the valve is arranged in the second flow segment.

[0009] In this way, by installing the valve inside the second flow segment through an opening formed on the side of the tank bottom in the second flow segment, it can be easily installed, and the first flow segment, the second flow segment and the third flow segment formed by the flow channel are connected in succession, and the valve is set in the second flow segment, so that the flow channel can be controlled by the movement of the valve.

[0010] In some embodiments, the tank body comprises a conduit mounted on the tank bottom, and a free end of the conduit forms the second liquid outlet.

[0011] In this way, by installing the conduit on the tank body and forming a second liquid outlet at the free end of the conduit, it can be difficult for the liquid refrigerant in the liquid storage tank to flow out of the liquid storage tank when the vehicle is at high temperature, so that the liquid refrigerant can be stored in the liquid storage tank, and the shape of the conduit is convenient for setting the height of the second liquid outlet.

[0012] In certain embodiments, the conduit is in communication with the flow channel to connect the liquid storage chamber with the outside.

[0013] In this way, by connecting the conduit with the flow channel, the second liquid outlet and the first liquid outlet share the flow channel, which can simplify the structure of the tank body, eliminate the need for an additional flow channel to connect the conduit, and reduce costs.

[0014] In certain embodiments, the flow channel is formed with a first flow segment, a second flow segment, and a third flow segment, the first flow segment extends downward from the first liquid outlet, the second flow segment extends substantially horizontally from the side of the tank bottom and is connected to the first flow segment, the third flow segment extends upward from the bottom surface of the tank bottom and is connected to the second flow segment, the valve is disposed in the second flow segment, and the flow channel is further formed with a fourth flow segment, the fourth flow segment extends downward from the interface between the conduit and the tank bottom and is connected to the third flow segment.

[0015] In this way, by forming a fourth flow channel on the flow channel, and the fourth flow channel connects the conduit and the third flow segment, the liquid refrigerant in the liquid storage chamber flows from the conduit through the fourth flow segment into the third flow segment, and then flows into the outside of the tank body through the third flow segment, thereby adjusting the liquid storage amount in the liquid storage chamber and simplifying the structure of the tank body to save costs.

[0016] In certain embodiments, the conduit is shaped as a U-shaped tube.

[0017] In this way, by designing the conduit as a U-shaped tube and directing the second liquid outlet toward the bottom of the tank, it is possible to prevent the refrigerant from directly entering the second liquid outlet and flowing out of the tank when entering the tank body, making it impossible for the tank body to store the refrigerant.

[0018] In certain embodiments, the valve is a solenoid valve.

[0019] In this way, by setting the valve as a solenoid valve, the valve can respond quickly to closing and opening, and there is no need to manually control closing and opening. When the vehicle adjusts the heating or cooling mode, the valve can be automatically controlled to open or close.

[0020] In some embodiments, the tank body includes a tank cover and a tank shell, the tank cover is connected to the tank bottom through the tank shell, and the tank cover is formed with a liquid inlet.

[0021] In this way, the tank body can form a liquid storage cavity by connecting the tank cover and the tank bottom included in the tank body through the tank shell, and a liquid inlet is provided on the tank cover of the tank body, so that the refrigerant can be guided into the liquid storage cavity for storage.

[0022] In some embodiments, the tank is cylindrical.

[0023] In this way, by setting the shape of the tank body to be columnar, wherein the columnar shape may be a cylinder, a prism, etc., the tank body can be adapted to different vehicle models, and refrigerant can be stored for vehicles of different models.

[0024] The air conditioning device according to the embodiment of the present application includes the liquid storage tank described in any one of the above items.

DETAILED DESCRIPTION

[0037] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0039] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. In an example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection, or they can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0040] In the embodiments of the present application, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being “above”, “above”, and “above” a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] When the external ambient temperature of vehicle 1000 is high, vehicle 1000 needs to start the air-conditioning device 100 to cool down the interior of vehicle 1000, or when the external temperature of vehicle 1000 is low, vehicle 1000 needs to start the air-conditioning device 100 to heat up the interior of vehicle 1000. Therefore, depending on whether the air-conditioning device 100 of vehicle 100 is used for cooling or heating, the amount of refrigerant in the liquid storage tank 10 that needs to circulate in the air-conditioning device 100 is also different, so the amount of liquid stored in the liquid storage tank 10 needs to be controlled.

[0042] For example, when the car is in a high temperature environment, the air conditioning device 100 of the car needs to perform cooling, and only a small amount of refrigerant is required to participate in the circulation in the air conditioning device 100. Therefore, it is hoped that the refrigerant entering the liquid storage tank 10 will flow out of the liquid storage tank 10 less, so that more liquid refrigerant can be stored in the liquid storage tank 10. When the car is in a low temperature environment, the air conditioning device 100 of the car needs to perform heating, and more refrigerant is required to participate in the circulation in the air conditioning device 100. Therefore, it is hoped that more refrigerant will flow out of the liquid storage tank 10, so that less liquid refrigerant can be stored in the liquid storage tank 10. However, the current liquid storage tank 10 cannot adjust the amount of liquid stored in the liquid storage tank 10 at different temperatures of the vehicle 1000.

[0043] To do this, see Figure 1 , Figure 2 and Figure 3The liquid storage tank 10 of the embodiment of the present application includes a tank body 11 and a valve 115. The tank body 11 is formed with a liquid storage cavity 116, a first liquid outlet 1111 and a second liquid outlet 1141. When the liquid storage tank 10 is in a working state, the second liquid outlet 1141 is higher than the first liquid outlet 1111; the valve 115 is arranged at the first liquid outlet 1111.

[0044] In this way, when the car is in a high temperature environment, the valve 115 can be closed, and the liquid refrigerant can only flow out of the liquid storage tank 10 through the second liquid outlet 1141 under the pressure in the liquid storage tank 10. When the car is in a low temperature environment, the valve 115 is opened, and the liquid refrigerant flows out of the liquid storage tank 10 through the first liquid outlet 1111 under the pressure in the liquid storage tank 10. Since the second liquid outlet 1141 is higher than the first liquid outlet 1111, it is more difficult for the liquid refrigerant to flow out of the liquid storage tank 10 when the car is in a high temperature environment than when the car is in a low temperature environment. Therefore, the liquid storage tank 10 can store more refrigerant, and vice versa.

[0045] Specifically, the air conditioning device 100 of the vehicle 1000 includes a liquid storage tank 10, which can be used to store liquid refrigerant. The liquid storage tank 10 includes a tank body 11, and the shape of the tank body 11 is columnar, for example, the shape of the tank body 11 can be cylindrical, quadrangular prism-shaped or multi-prism-shaped. The tank body 11 is formed with a liquid storage cavity 116, and the liquid storage cavity 116 can be used to store refrigerant, and the shape of the liquid storage cavity 116 is adapted to the shape of the tank body 11, so that the tank body 11 and the liquid storage cavity 116 formed by the tank body 11 can be adapted to air conditioning devices 100 of different models, and the air conditioning devices 100 of different models of vehicles 1000 can store refrigerant.

[0046] The liquid storage tank 10 is also formed with a first liquid outlet 1111, a second liquid outlet 1141 and a valve 115. The first liquid outlet 1111 and the second liquid outlet 1141 are both used to allow the liquid refrigerant in the liquid storage chamber 116 to flow out of the liquid storage tank 10 to participate in the heating or cooling cycle of the air conditioning device 100. The valve 115 can be used to control the liquid refrigerant to flow out from the first liquid outlet 1111 or the second liquid outlet 1141. The valve 115 can be a solenoid valve. When the vehicle 1000 switches the mode of the air conditioning device 100, the valve 115 can receive an electrical signal to control the first liquid outlet 1111 to open or close, and when the valve 115 is closed, the liquid refrigerant can squeeze the valve 115, so that the sealing of the valve 115 is further improved. Therefore, when the vehicle 1000 adjusts the heating or heating mode, the valve 115 can automatically control the opening or closing, so that the liquid storage tank 10 can quickly respond to the closing and opening of the valve 115, and there is no need to manually control the closing and opening.

[0047] When the air conditioning device 100 is started in the vehicle 1000, that is, the liquid storage tank 10 is in working condition, the height of the second liquid outlet 1141 in the liquid storage chamber 116 is higher than the height of the first liquid outlet 1111 in the liquid storage chamber 116, and a valve 115 is provided at the first liquid outlet 1111. The valve 115 is used to control the first liquid outlet 1111 and the second liquid outlet 1141 to respectively correspond to the liquid refrigerant in the liquid storage chamber 116 to flow out of the outlet of the liquid storage tank 10 when the vehicle 1000 is in different ambient temperatures.

[0048] For example, when the car is in a high temperature environment, the air conditioning device 100 of the car needs to perform cooling, and only a small amount of refrigerant is required to participate in the circulation in the air conditioning device 100. Therefore, the control valve 115 closes the first liquid outlet 1111, so that the liquid refrigerant flows out from the second liquid outlet 1141, so that it can be determined that the refrigerant entering the liquid storage tank 10 flows out of the liquid storage tank 10 less, and further more liquid refrigerant is stored in the liquid storage tank 10. When the car is in a low temperature environment, the air conditioning device 100 of the car needs to perform heating, and more refrigerant is required to participate in the circulation in the air conditioning device 100. Therefore, the control valve 115 opens the first liquid outlet 1111, so that the liquid refrigerant flows out from the first liquid outlet 1111, so that it can be determined that the refrigerant entering the liquid storage tank 10 flows out of the liquid storage tank 10 more, and further less liquid refrigerant is stored in the liquid storage tank 10.

[0049] See also Figure 3 and Figure 4 In some embodiments, the tank body 11 includes a tank bottom 111. When the liquid storage tank 10 is in working state, the tank bottom 111 is located below the liquid storage cavity 116. The tank bottom 111 is formed with a flow channel 117. The flow channel 117 passes through the tank bottom 111 and connects to the liquid storage cavity 116 to form a first liquid outlet 1111.

[0050] In this way, by arranging the first liquid outlet 1111 on the upper surface of the tank bottom 111, that is, the bottom surface of the liquid storage cavity 116, that is, the first liquid outlet 1111 is located at the bottom of the liquid storage cavity 116, and a connection between the liquid storage cavity 116 and the outside of the tank body 11 is formed on the tank bottom 111, it is possible to open the valve 115 when the car is in a low temperature environment, and the liquid refrigerant can more easily flow out of the liquid storage tank 10 through the first liquid outlet 1111 under the pressure in the liquid storage tank 10.

[0051] Specifically, the tank body 11 also includes a tank bottom 111. When the liquid storage tank 10 is in working condition, the tank bottom 111 is located below the liquid storage cavity 116, which can ensure that the liquid storage tank 10 remains vertically installed in the vehicle 1000, so that when the liquid storage tank 10 is in working condition, the liquid refrigerant in the liquid storage cavity 116 will not flow out of the liquid storage tank 10 due to the bumps of the vehicle 1000.

[0052] A flow channel 117 is formed inside the tank bottom 111. The shape of the flow channel 117 can be a circular pipe or a square pipe, etc., so that the flow channel 117 can be used to transport liquid refrigerant. One end of the flow channel 117 can be connected to the liquid storage cavity 116 by penetrating the tank bottom 111, so that a first liquid outlet 1111 is formed at one end of the flow channel 117. The other end of the flow channel 117 can be connected to the outside of the liquid storage tank 10 by penetrating the tank bottom 111, so that the liquid refrigerant in the liquid storage cavity 116 can flow out of the liquid storage tank 10.

[0053] Please refer again Figure 2 In some embodiments, the flow channel 117 is formed with a first flow segment 1171, a second flow segment 1172 and a third flow segment 1173. When the liquid storage tank 10 is in working condition, the first flow segment 1171 extends downward from the first liquid outlet 1111, the second flow segment 1172 extends substantially horizontally from the side of the tank bottom 111 and is connected to the first flow segment 1171, the third flow segment 1173 extends upward from the bottom surface of the tank bottom 111 and is connected to the second flow segment 1172, and the valve 115 is disposed in the second flow segment 1172.

[0054] In this way, by installing the valve 115 inside the second flow segment 1172 through the opening formed in the second flow segment 1172 on the side of the tank bottom 111, it can be easily installed, and the first flow segment 1171, the second flow segment 1172 and the third flow segment 1173 formed by the flow channel 117 are connected in succession, and the valve 115 is set in the second flow segment 1172, so that the flow channel 117 can be controlled to be open and closed by the movement of the valve 115.

[0055] Specifically, a first flow segment 1171, a second flow segment 1172 and a third flow segment 1173 are formed on the flow channel 117, and the first flow segment 1171, the second flow segment 1172 and the third flow segment 1173 can all be used to transport liquid refrigerant. When the liquid storage tank 10 is in a working state, the first flow segment 1171 can extend from the first liquid outlet 1111 in a direction perpendicular to the tank bottom 111 until it is connected with the second flow segment 1172. The second flow segment 1172 can extend in a direction substantially horizontal to the side of the tank bottom 111 until it is communicated with the third flow segment 1173, and a valve 115 is provided in the second flow segment 1172. The valve 115 can move the second flow segment 1172. When the valve 115 moves to the side close to the tank bottom 111, the first flow segment 1171 can be communicated with the third flow segment 1173 through the second flow segment 1172. When the valve 115 moves to the side close to the tank bottom 111, the communication between the first flow segment 1171 and the third flow segment 1173 can be blocked. The third flow segment 1173 can extend from the bottom surface of the tank bottom 111 in a direction perpendicular to the tank bottom 111 until it is communicated with the second flow segment 1172, and one end of the third flow segment 1173 can penetrate the tank bottom 111 to communicate with the outside of the liquid storage tank 10. Thus, the liquid refrigerant in the liquid storage chamber 116 can flow from the first flow segment 1171 into the second flow segment 1172 , then into the third flow segment 1173 , and finally flow from the third flow segment 1173 into the outside of the liquid storage tank 10 .

[0056] Please refer again Figure 2 In some embodiments, the tank body 11 includes a conduit 114 , which is installed on the tank bottom 111 , and a free end of the conduit 114 forms a second liquid outlet 1141 .

[0057] In this way, by installing the conduit 114 on the tank body 11 and forming a second liquid outlet 1141 at the free end of the conduit 114, it is possible to make it difficult for the liquid refrigerant in the liquid storage tank 10 to flow out of the liquid storage tank 10 when the vehicle 1000 is at a high temperature, so that the liquid refrigerant can be stored in the liquid storage tank 10, and the shape of the conduit 114 facilitates setting the height of the second liquid outlet 1141.

[0058] Specifically, the tank body 11 also includes a conduit 114, which can be used to transmit liquid refrigerant. The conduit 114 can be a square tube, a round tube, etc., and the shape of the conduit 114 can be a U-shaped tube. The conduit 114 is installed on the tank bottom 111, that is, one end of the conduit 114 is connected to the tank bottom 111 by welding, and the free end of the conduit 114 is formed with a second liquid outlet 1141. It should be noted that the free end of the conduit 114 is the end away from the tank bottom 111, and the opening of the second liquid outlet 1141 faces the tank bottom 111. Therefore, by designing the shape of the conduit 114 as a U-shaped tube and facing the second liquid outlet 1141 to face the tank bottom 111, it can be prevented that when the liquid refrigerant enters the tank body 11, it directly enters the second liquid outlet 1141 and flows out of the tank body 11, so that the tank body 11 cannot store refrigerant.

[0059] Optionally, according to the different amounts of liquid refrigerant that need to be stored in different models of vehicles 1000, the distance from the second liquid outlet 1141 on the conduit 114 to the tank bottom 111 can be adjusted to make the liquid storage tank 10 adapt to air conditioning devices 100 of different models.

[0060] See also Figure 3 In certain embodiments, the conduit 114 is in communication with the flow channel 117 to connect the liquid storage chamber 116 and the outside.

[0061] In this way, by connecting the conduit 114 with the flow channel 117, the second liquid outlet 1141 and the first liquid outlet 1111 share the flow channel 117, which can simplify the structure of the tank body 11, eliminate the need for an additional flow channel 117 to connect the conduit 114, and reduce costs.

[0062] Specifically, one end of the conduit 114 installed on the tank bottom 111 can be connected to the flow channel 117, so that the liquid refrigerant in the liquid storage chamber 116 can enter the conduit 114 through the second liquid outlet 1141, then enter the flow channel 117, and finally flow out of the liquid storage chamber 116 through the flow channel 117 to the outside of the liquid storage tank 10.

[0063] Please refer again Figure 3 In some embodiments, the flow channel 117 is formed with a first flow segment 1171, a second flow segment 1172 and a third flow segment 1173, the first flow segment 1171 extends downward from the first liquid outlet 1111, the second flow segment 1172 extends substantially horizontally from the side of the tank bottom 111 and is connected to the first flow segment 1171, the third flow segment 1173 extends upward from the bottom surface of the tank bottom 111 and is connected to the second flow segment 1172, the valve 115 is disposed in the second flow segment 1172, and the flow channel 117 is further formed with a fourth flow segment 1174, the fourth flow segment 1174 extends downward from the interface between the conduit 114 and the tank bottom 111 and is connected to the third flow segment 1173.

[0064] In this way, by forming a fourth flow channel 117 on the flow channel 117, and the fourth flow channel 117 connecting the conduit 114 and the third flow segment 1173, the liquid refrigerant in the liquid storage chamber 116 flows from the conduit 114 through the fourth flow segment 1174 into the third flow segment 1173, and then flows into the outside of the tank body 11 through the third flow segment 1173, thereby adjusting the liquid storage amount in the liquid storage chamber 116 and simplifying the structure of the tank body 11 to save costs.

[0065] Specifically, in addition to the first flow segment 1171, the second flow segment 1172 and the third flow segment 1173, the flow channel 117 also forms a fourth flow segment 1174. The fourth flow segment 1174 can be used to transport liquid refrigerant, and the fourth flow segment 1174 can extend downward from the interface connecting the conduit 114 and the tank bottom 111 in a direction perpendicular to the tank bottom 111 until it is connected with the third flow segment 1173. Thus, the liquid refrigerant in the liquid storage chamber 116 can enter the conduit 114 through the second liquid outlet 1141, then enter the fourth flow segment 1174 and then flow into the third flow segment 1173, and finally flow out of the liquid storage chamber 116 from the flow channel 117 of the third flow segment 1173 to the outside of the liquid storage tank 10.

[0066] See also Figure 5 , Figure 6 and Figure 7 In some embodiments, the tank body 11 includes a tank cover 113 and a tank shell 112 , the tank cover 113 is connected to the tank bottom 111 through the tank shell 112 , and the tank cover 113 is formed with a liquid inlet 1133 .

[0067] In this way, by connecting the tank cover 113 and the tank bottom 111 included in the tank body 11 through the tank shell 112, the tank body 11 can form a liquid storage chamber 116, and a liquid inlet 1133 is provided on the tank cover 113 of the tank body 11, so that the refrigerant can be guided into the liquid storage chamber 116 for storage.

[0068] Specifically, the tank body 11 also includes a tank cover 113 and a tank shell 112. The tank cover 113 and the tank bottom 111 can be connected to the tank shell 112 by welding to form the tank body 11, and the tank cover 113 and the tank bottom 111 can be mold castings, so that they can be used as universal parts to assemble the liquid storage tank 10, thereby reducing the cost of redeveloping and designing the tank cover 113, the tank shell 112 and the tank bottom 111 and the cost of opening molds for the tank cover 113, the tank shell 112 and the tank bottom 111.

[0069] Since different models of vehicles 1000 require different amounts of liquid refrigerant to be stored, the upper limit of the amount of liquid stored in the liquid storage chamber 116 can be determined by designing the height of the tank shell 112 so that the liquid storage tank 10 can be adapted to air conditioning devices 100 of different models.

[0070] Optionally, a mounting hole 1131 is formed on the tank cover 113 , and the mounting hole 1131 can fix the liquid storage tank 10 in the air conditioning device 100 by screwing a nut therein, thereby preventing the liquid refrigerant from flowing out of the liquid storage tank 10 due to the bumping of the vehicle 1000 .

[0071] Optionally, a third liquid outlet 1132 may be formed on the tank cover 113, the conduit 114 may be in the shape of a straight tube, the conduit 114 is connected to the tank cover 113 by welding, and the conduit 114 can be connected to the outside of the liquid storage tank 10 through the third liquid outlet 1132. The liquid refrigerant in the liquid storage chamber 116 flows into the conduit 114 through the second liquid outlet 1141, and then flows out of the liquid storage tank 10 through the third liquid outlet 1132.
