Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to an air conditioner and a vehicle. Background Art

[0002] Vehicles are usually equipped with heat pump air conditioners, which absorb heat from the environment and release the heat into the vehicle to heat the interior of the vehicle. However, when the ambient temperature is low, the heat pump air conditioner can absorb less heat from the environment, which will result in poor heating effect of the heat pump air conditioner.

[0003] The prior art CN115465040A provides a vehicle air-conditioning heat pump system with a waste heat recovery function, which conducts the heat generated by the motor and electronic control module when it is working to the vehicle compartment through a fan, thereby improving the heating effect of the vehicle. The heat conduction efficiency of the above method is poor and a fan is required, which increases the energy consumption of the vehicle. Utility Model Content

[0004] The present application provides an air conditioner and a vehicle to solve the problem of poor heating effect of the air conditioner. The technical solution adopted by the utility model is as follows:

[0005] According to the first aspect involved in the present application, there is provided an air conditioner, comprising a compressor, a gas-liquid separator, a heat exchange system and a heat conductor. The gas-liquid separator is spaced apart from the compressor, and the outlet of the gas-liquid separator is connected to the inlet of the compressor, so as to introduce a gaseous refrigerant into the compressor. The heat exchange system is connected between the outlet of the compressor and the inlet of the gas-liquid separator, and the refrigerant can circulate between the compressor, the heat exchange system and the gas-liquid separator, so that the air conditioner is in a heating mode or a cooling mode. When the air conditioner is in a heating mode, the heat conductor can be located between the compressor and the gas-liquid separator, and is thermally conductive with the compressor and the gas-liquid separator. When the air conditioner is in a cooling mode, the heat conductor is separated from at least one of the compressor and the gas-liquid separator.

[0006] According to the above technical means, when the temperature is high in summer, the air conditioner can be put into cooling mode to cool down the interior of the vehicle, or when the temperature is low in winter, the air conditioner can be put into heating mode to heat the interior of the vehicle, thereby improving the comfort of the driver and passengers when driving the vehicle and improving the user experience of the vehicle.

[0007] When the air conditioner is in heating mode, since the compressor and the gas-liquid separator are thermally connected through the heat conductor, the heat generated by the compressor when it is working can be transferred to the gas-liquid separator through the heat conductor, and then the refrigerant in the gas-liquid separator is heated, thereby increasing the temperature of the refrigerant entering the compressor. This can improve the heating effect of the air conditioner and prevent the heating effect of the air conditioner from being reduced by the external environment of the vehicle.

[0008] Furthermore, when the air conditioner is in cooling mode, since the heat conductor is separated from at least one of the compressor and the gas-liquid separator, the heat generated by the compressor will not be conducted to the gas-liquid separator through the heat conductor during the cooling process of the air conditioner. This can prevent the refrigerant temperature entering the compressor from being too high, thereby preventing the compressor from overheating and ensuring the normal operation of the compressor.

[0009] In addition, compared to using a PTC heater to heat the refrigerant to improve the heating effect of the air conditioner, the heat generated by the compressor when it is working can be recovered through the setting of the heat conductor, which will not increase the energy consumption of the air conditioner and can improve the utilization efficiency of the air conditioner.

[0010] In some embodiments of the present application, when the air conditioner is in cooling mode, the heat conductive element is separated from the gas-liquid separator and is thermally connected to the compressor.

[0011] According to the above technical means, when the air conditioner is in cooling mode, since the heat conducting part is thermally connected to the compressor, during the cooling process of the air conditioner, the heat generated by the compressor will be continuously conducted to the air through the heat conducting part, thereby dissipating the heat of the compressor. This can further ensure the operating temperature of the compressor, avoid overheating of the compressor, and thus ensure the normal operation of the compressor.

[0012] In some embodiments of the present application, the heat conducting member includes a heat conducting liquid. The air conditioner includes a first heat exchange shell and a second heat exchange shell. The first heat exchange shell is connected between the gas-liquid separator and the compressor, and a first heat exchange cavity is provided in the first heat exchange shell. When the air conditioner is in a heating mode, the heat conducting liquid is located in the first heat exchange cavity. The second heat exchange shell is connected to the compressor and is spaced apart from the gas-liquid separator, and a second heat exchange cavity is provided in the second heat exchange shell. When the air conditioner is in a cooling mode, the heat conducting liquid is located in the second heat exchange cavity.

[0013] According to the above technical means, when the air conditioner is in heating mode, since the first heat exchange shell is connected between the gas-liquid separator and the compressor, and the heat transfer liquid is located in the first heat exchange chamber, the heat generated by the compressor when it is working can be conducted to the heat transfer liquid through the first heat exchange shell, and then conducted to the gas-liquid separator through the heat transfer liquid, thereby heating the refrigerant in the gas-liquid separator. Compared with using metal or heat pipes to conduct heat, the heat transfer efficiency of the heat transfer liquid is higher, which can improve the heating effect of the air conditioner.

[0014] When the air conditioner is in cooling mode, since the second heat exchange shell is connected to the compressor and is spaced apart from the gas-liquid separator, the heat transfer liquid is located in the second heat exchange chamber. Therefore, the heat generated by the compressor when it is working can be conducted to the heat transfer liquid through the second heat exchange shell, and then dissipated into the air through the heat transfer liquid to achieve heat dissipation of the compressor. Compared with using metal or heat pipes to conduct heat, the heat transfer efficiency of the heat transfer liquid is higher, which can improve the heat dissipation effect of the compressor.

[0015] In some embodiments of the present application, the air conditioner includes a driving device, which is connected to the first heat exchange chamber and the second heat exchange chamber, and is used to drive the heat transfer liquid to switch between the first heat exchange chamber and the second heat exchange chamber.

[0016] According to the above technical means, when the air conditioner is heating, the driving component can drive the heat-conducting liquid to switch to the first heat exchange chamber, and when the air conditioner is cooling, the driving component can drive the heat-conducting liquid to switch to the second heat exchange chamber, so as to use the heat generated by the compressor when the air conditioner is heating to heat the refrigerant in the gas-liquid separator, and dissipate the heat of the compressor when the air conditioner is cooling, so as to improve the heating effect of the air conditioner and ensure the normal operation of the compressor.

[0017] In some embodiments of the present application, along the arrangement direction of the compressor and the gas-liquid separator, the first heat exchange chamber penetrates the first heat exchange shell, and the compressor and the gas-liquid separator respectively block the two end openings of the first heat exchange chamber.

[0018] According to the above technical means, when the air conditioner is heating, since the compressor and the gas-liquid separator respectively block the openings at both ends of the first heat exchange chamber, the heat-conducting liquid can contact the compressor and the gas-liquid separator at the same time, and the heat generated by the compressor when working can be directly transferred to the heat-conducting liquid, and the heat in the heat-conducting liquid can be directly transferred to the gas-liquid separator. In this way, the setting of the first heat exchange chamber can speed up the rate of heat transfer from the compressor to the gas-liquid separator, and reduce the loss of heat during the transfer process, thereby increasing the amount of heat transferred from the compressor to the gas-liquid separator and improving the heating effect of the air conditioner.

[0019] In some embodiments of the present application, the first heat exchange shell includes a first annular shell and a second annular shell. The gas-liquid separator blocks an opening at one end of the first annular shell. The compressor blocks an opening at one end of the second annular shell. The other end opening of the second annular shell is sealed and connected to the other end opening of the first annular shell.

[0020] According to the above technical means, the first annular shell and the second annular shell can be processed separately, the first annular shell is connected to the gas-liquid separator, and the second annular shell is connected to the compressor, and then the first annular shell and the second annular shell are connected together. Compared with the first heat exchange shell processed by one-piece molding, the sizes of the first annular shell and the second annular shell are smaller, and the first annular shell and the second annular shell can be processed and installed more easily, thereby facilitating the processing and installation of the first heat exchange shell.

[0021] In some embodiments of the present application, the other end of the first annular shell is provided with a first connecting portion, the other end of the second annular shell is provided with a second connecting portion, and the first connecting portion and the second connecting portion are detachably connected. The air conditioner further includes a sealing member, which contacts both the first annular shell and the second annular shell and is used to seal the gap between the other end opening of the first annular shell and the other end opening of the second annular shell.

[0022] According to the above technical means, the seal can prevent the heat-conducting liquid from leaking out of the first heat exchange cavity to ensure the heat-conducting effect of the heat-conducting liquid. And compared with the sealing connection between the other end of the second annular shell and the other end of the first annular shell by welding, the detachable connection between the first connecting part and the second connecting part can simplify the connection process between the other end of the second annular shell and the other end of the first annular shell, thereby facilitating the connection between the first annular shell and the second annular shell. And when the first annular shell or the second annular shell needs to be maintained, the first annular shell and the second annular shell can be quickly separated by disassembling the first connecting part and the second connecting part, so as to facilitate the maintenance of the first annular shell or the second annular shell.

[0023] In some embodiments of the present application, the air conditioner further includes a first heat sink, which is connected to the compressor and is located in the first heat exchange chamber.

[0024] According to the above technical means, since the first heat sink is connected to the compressor, the heat generated by the compressor when it is working can be conducted to the first heat sink, and since the first heat sink is located in the first heat exchange cavity, when the air conditioner is in heating mode, the heat-conducting liquid located in the first heat exchange cavity can contact the first heat sink. In this way, when the air conditioner is in heating mode, the heat generated by the compressor when it is working can be directly conducted to the heat-conducting liquid through the first heat sink, which can speed up the rate at which the heat generated by the compressor when it is working is conducted to the heat-conducting liquid compared to the heat conduction through the first heat exchange shell, and can increase the heat dissipation area when the heat on the compressor is conducted to the heat-conducting liquid compared to the direct contact between the heat-conducting liquid and the compressor, and can also speed up the rate at which the heat generated by the compressor when it is working is conducted to the heat-conducting liquid, thereby further improving the heating effect of the air conditioner.

[0025] In some embodiments of the present application, the air conditioner further includes a second heat sink, which is disposed in the gas-liquid separator and connected to an inner wall surface of the gas-liquid separator on one side facing the compressor.

[0026] According to the above technical means, when the air conditioner is in heating mode, after the heat generated by the compressor is transferred to the gas-liquid separator, the heat of the gas-liquid separator can be transferred to the second heat sink, which can increase the heat dissipation area when the heat on the gas-liquid separator is transferred to the refrigerant compared to the case where the refrigerant is only in contact with the gas-liquid separator, thereby accelerating the rate at which the heat on the gas-liquid separator is transferred to the refrigerant, accelerating the heating of the refrigerant, and thus improving the heating effect of the air conditioner. And because the second heat sink is connected to the inner wall of the gas-liquid separator facing the compressor, the heat in the heat-conducting liquid can be transferred to the second heat sink more quickly after being transferred to the gas-liquid separator, thereby further accelerating the rate at which the heat on the gas-liquid separator is transferred to the refrigerant.

[0027] According to a second aspect of the present application, a vehicle is provided, comprising the above-mentioned air conditioner.

[0028] Therefore, the above technical features of the present application have the following beneficial effects:

[0029] (1) The present application, through the provision of a heat-conducting member, can transfer the heat generated by the compressor when the air conditioner is in heating mode to the gas-liquid separator, thereby heating the refrigerant in the gas-liquid separator, thereby increasing the temperature of the refrigerant entering the compressor, thereby improving the heating effect of the air conditioner, and when the air conditioner is in cooling mode, preventing the heat generated by the compressor from being transferred to the gas-liquid separator, thereby preventing the temperature of the refrigerant entering the compressor from being too high, thereby preventing the compressor from overheating and ensuring the normal operation of the compressor.

[0030] (2) The present application provides a heat-conducting member so that when the air conditioner is in cooling mode, the compressor can be cooled. This can further ensure the operating temperature of the compressor, prevent the compressor from overheating, and thus ensure the normal operation of the compressor.

[0032] (4) The present application provides a driving device to realize the switching of the heat-conducting liquid between the first heat exchange chamber and the second heat exchange chamber, thereby improving the heating effect of the air conditioner and the heat dissipation effect of the compressor.

[0033] (5) The present application, through the setting of the first heat exchange chamber, can accelerate the rate of heat conduction from the compressor to the gas-liquid separator and reduce the heat loss during the conduction process, thereby increasing the amount of heat conducted from the compressor to the gas-liquid separator and improving the heating effect of the air conditioner.

[0034] (6) The present application can more easily process and install the first annular shell and the second annular shell through the provision of the first annular shell and the second annular shell, thereby facilitating the processing and installation of the first heat exchange shell.

[0035] (7) The present application can facilitate the connection of the first annular shell and the second annular shell through the provision of the first connecting portion and the second connecting portion, and facilitate the maintenance of the first annular shell or the second annular shell.

[0036] (8) By providing a first heat sink, the present application can accelerate the rate at which the heat generated by the compressor when it is working is transferred to the heat-conducting liquid, thereby further improving the heating effect of the air conditioner.

[0037] (9) In the present application, by providing a second heat sink, the heat in the heat-conducting liquid can be more quickly transferred to the second heat sink after being transferred to the gas-liquid separator, thereby further accelerating the rate at which the heat on the gas-liquid separator is transferred to the refrigerant.

DETAILED DESCRIPTION

[0045] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0047] The vehicle 100 is usually equipped with a heat pump air conditioner 10, which absorbs heat from the environment and releases the heat to the interior of the vehicle 100 to heat the interior of the vehicle 100. However, when the ambient temperature is low, the heat pump air conditioner 10 can absorb less heat from the environment, which will result in a poor heating effect of the heat pump air conditioner 10.

[0048] Based on this, the present application provides a vehicle 100, such as Figure 1 , Figure 2 As shown, Figure 1 is a schematic diagram of the external structure of the vehicle 100, Figure 2 yes Figure 1 Schematic diagram of the structure of the air conditioner 10 of the vehicle 100, the vehicle 100 includes the air conditioner 10.

[0049] Specifically, if Figure 2 As shown, the air conditioner 10 includes a compressor 1 , a gas-liquid separator 2 and a heat exchange system 3 .

[0050] The gas-liquid separator 2 is spaced apart from the compressor 1 , and the outlet of the gas-liquid separator 2 is communicated with the inlet of the compressor 1 , so as to introduce the gaseous refrigerant into the compressor 1 .

[0051] The heat exchange system 3 is connected between the outlet of the compressor 1 and the inlet of the gas-liquid separator 2, and the refrigerant can circulate between the compressor 1, the heat exchange system 3 and the gas-liquid separator 2 to put the air conditioner 10 in heating mode or cooling mode.

[0052] Through the above settings, when the temperature is high in summer, the air conditioner 10 can be put into cooling mode to cool the interior of the vehicle 100, or when the temperature is low in winter, the air conditioner 10 can be put into heating mode to heat the interior of the vehicle 100, thereby improving the comfort of the driver and passengers when driving the vehicle 100 and improving the user experience of the vehicle 100.

[0053] Specifically, if Figure 2As shown, the heat exchange system 3 includes a first switch valve 31 , a second switch valve 32 , a third switch valve 33 , a fourth switch valve 34 , an in-vehicle condenser 35 , an in-vehicle evaporator 36 , an out-vehicle heat exchanger 37 , a first expansion valve 38 and a second expansion valve 39 .

[0054] The inlet of the first switch valve 31 is connected to the outlet of the compressor 1, and the outlet of the first switch valve 31 is connected to the inlet of the in-vehicle condenser 35; the outlet of the in-vehicle condenser 35 is connected to the inlet of the first expansion valve 38, and the outlet of the first expansion valve 38 is connected to the inlet of the outdoor heat exchanger 37, the inlet of the second switch valve 32 is connected to the outlet of the compressor 1, and the outlet of the second switch valve 32 is connected to the inlet of the outdoor heat exchanger 37; the outlet of the outdoor heat exchanger 37 is connected to the inlet of the third switch valve 33 and the inlet of the fourth switch valve 34, the outlet of the third switch valve 33 is connected to the inlet of the gas-liquid separator 2, the outlet of the fourth switch valve 34 is connected to the inlet of the second expansion valve 39, the outlet of the second expansion valve 39 is connected to the inlet of the in-vehicle evaporator 36, and the outlet of the in-vehicle evaporator 36 is connected to the inlet of the gas-liquid separator 2.

[0055] When the air conditioner 10 is in heating mode, the first switch valve 31, the first expansion valve 38, and the third switch valve 33 are opened, and the second switch valve 32 and the fourth switch valve 34 are closed. The refrigerant flowing out of the compressor 1 can flow through the first switch valve 31, the in-vehicle condenser 35, the first expansion valve 38, the out-vehicle heat exchanger 37, the third switch valve 33, and the gas-liquid separator 2 in sequence and then flow back to the compressor 1, absorb heat in the out-vehicle heat exchanger 37, and release heat in the in-vehicle condenser 35, thereby heating the interior of the vehicle 100.

[0056] When the air conditioner 10 is in cooling mode, the first switch valve 31 and the third switch valve 33 are closed, and the second switch valve 32, the fourth switch valve 34 and the second expansion valve 39 are opened. The refrigerant flowing out of the compressor 1 can flow through the second switch valve 32, the outdoor heat exchanger 37, the fourth switch valve 34, the second expansion valve 39, the indoor evaporator 36, and the gas-liquid separator 2 in sequence and then flow back to the compressor 1, release heat in the outdoor heat exchanger 37, and absorb heat in the indoor evaporator 36 to cool the interior of the vehicle 100.

[0057] In some embodiments, the air conditioner 10 further includes a heat conducting member, and when the air conditioner 10 is in a heating mode, the heat conducting member can be located between the compressor 1 and the gas-liquid separator 2, and is thermally connected to the compressor 1 and the gas-liquid separator 2. When the air conditioner 10 is in a cooling mode, the heat conducting member is separated from at least one of the compressor 1 and the gas-liquid separator 2.

[0058] It should be noted that the refrigerant in the gas-liquid separator 2 is a gaseous refrigerant at normal temperature and pressure or low temperature and low pressure. When the compressor 1 is working, the refrigerant in the compressor 1 will be compressed into a gaseous refrigerant at high temperature and high pressure, and the compressor 1 itself will also generate heat when working. Therefore, the temperature of the compressor 1 is higher than the temperature of the gas-liquid separator 2. When the compressor 1 and the gas-liquid separator 2 are thermally connected, the heat will be transferred from the compressor 1 to the gas-liquid separator 2.

[0059] Through the above-mentioned arrangement, when the air conditioner 10 is in the heating mode, since the compressor 1 and the gas-liquid separator 2 are thermally connected through the heat conductor, the heat generated by the compressor 1 when it is working can be conducted to the gas-liquid separator 2 through the heat conductor, and then the refrigerant in the gas-liquid separator 2 is heated, thereby increasing the temperature of the refrigerant entering the compressor 1. This can improve the heating effect of the air conditioner 10 and prevent the heating effect of the air conditioner 10 from being reduced by the external environment of the vehicle 100.

[0060] Furthermore, when the air conditioner 10 is in cooling mode, since the heat conductive member is separated from at least one of the compressor 1 and the gas-liquid separator 2, during the cooling process of the air conditioner 10, the heat generated by the compressor 1 will not be conducted to the gas-liquid separator 2 through the heat conductive member. This can prevent the refrigerant temperature entering the compressor 1 from being too high, thereby preventing the compressor 1 from overheating and ensuring the normal operation of the compressor 1.

[0061] In addition, compared to using a PTC heater to heat the refrigerant to improve the heating effect of the air conditioner 10, the heat generated by the compressor 1 when it is working can be recovered by setting a heat conductor, which will not increase the energy consumption of the air conditioner 10 and can improve the utilization efficiency of the air conditioner 10.

[0062] On this basis, in some embodiments, when the air conditioner 10 is in cooling mode, the heat conducting element is separated from the gas-liquid separator 2 and is thermally connected to the compressor 1 .

[0063] Through the above-mentioned arrangement, when the air conditioner 10 is in the cooling mode, since the heat conducting member is thermally connected to the compressor 1, during the cooling process of the air conditioner 10, the heat generated by the compressor 1 will be continuously conducted to the air through the heat conducting member, thereby dissipating the heat of the compressor 1. This can further ensure the operating temperature of the compressor 1, avoid overheating of the compressor 1, and thus ensure the normal operation of the compressor 1.

[0064] In some embodiments, the heat conductor includes a heat pipe, which is connected to the compressor 1 via a rotating shaft. When the air conditioner 10 is in a cooling mode, the heat pipe can rotate between the compressor 1 and the gas-liquid separator 2 and contact both the compressor 1 and the gas-liquid separator 2 to achieve thermal conduction between the compressor 1 and the gas-liquid separator 2.

[0065] When the air conditioner 10 is in cooling mode, the heat pipe can rotate to one side of the compressor 1 , separate from the gas-liquid separator 2 , and contact the compressor 1 , so as to be thermally conductive only with the compressor 1 to dissipate heat from the compressor 1 .

[0066] In other embodiments, the thermally conductive element includes a thermally conductive liquid.

[0067] Exemplarily, the heat-conducting liquid may be water, oil, Freon, alkane, or the like.

[0068] like Figure 3 , Figure 4 As shown, Figure 3 yes Figure 2 Schematic diagram of the external structure of the gas-liquid separator 2 and the compressor 1, Figure 4 yes Figure 3 Schematic diagram of the exploded structure of the gas-liquid separator 2, the compressor 1 and the first heat exchange shell 5, the air conditioner 10 also includes the first heat exchange shell 5, the first heat exchange shell 5 is connected between the gas-liquid separator 2 and the compressor 1, and a first heat exchange cavity 51 is provided in the first heat exchange shell 5. When the air conditioner 10 is in the heating mode, the heat transfer liquid is located in the first heat exchange cavity 51.

[0069] Through the above-mentioned arrangement, when the air conditioner 10 is in the heating mode, since the first heat exchange shell 5 is connected between the gas-liquid separator 2 and the compressor 1, and the heat transfer liquid is located in the first heat exchange chamber 51, the heat generated by the compressor 1 when it is working can be conducted to the heat transfer liquid through the first heat exchange shell 5, and then conducted to the gas-liquid separator 2 through the heat transfer liquid, thereby heating the refrigerant in the gas-liquid separator 2. Compared with using metal or heat pipes to conduct heat, the heat transfer efficiency of the heat transfer liquid is higher, which can improve the heating effect of the air conditioner 10.

[0070] like Figure 3 , Figure 4 As shown, the air conditioner 10 further includes a second heat exchange shell 6, which is connected to the compressor 1 and spaced apart from the gas-liquid separator 2, and a second heat exchange cavity is provided in the second heat exchange shell 6. When the air conditioner 10 is in cooling mode, the heat transfer liquid is located in the second heat exchange cavity.

[0071] Through the above-mentioned arrangement, when the air conditioner 10 is in the cooling mode, since the second heat exchange shell 6 is connected to the compressor 1 and is spaced apart from the gas-liquid separator 2, the heat transfer liquid is located in the second heat exchange chamber. Therefore, the heat generated by the compressor 1 when working can be conducted to the heat transfer liquid through the second heat exchange shell 6, and then dissipated into the air through the heat transfer liquid to achieve heat dissipation of the compressor 1. Compared with the heat conduction using metal or heat pipes, the heat transfer efficiency of the heat transfer liquid is higher, which can improve the heat dissipation effect of the compressor 1.

[0072] Furthermore, since the heat transfer liquid is located in the second heat exchange chamber, there is no heat transfer liquid in the first heat exchange chamber 51, so that the heat generated by the compressor 1 during operation is prevented from being transferred to the gas-liquid separator 2 through the second heat exchange shell 6 and the heat transfer liquid, thereby preventing the compressor 1 from overheating.

[0073] In addition, since the heat transfer liquid is located in the first heat exchange chamber 51 when the air conditioner 10 is in the cooling mode, there is no heat transfer liquid in the second heat exchange chamber. This can prevent the heat generated by the compressor 1 when it is working from being dissipated into the air through the second heat exchange shell 6 and the heat transfer liquid, thereby ensuring that the heat generated by the compressor 1 when it is working is conducted to the gas-liquid separator 2, thereby ensuring the heating effect of the air conditioner 10.

[0074] In some embodiments, Figure 3 , Figure 4 As shown, the air conditioner 10 further includes a driving device 7, which is in communication with the first heat exchange chamber 51 and the second heat exchange chamber, and is used to drive the heat transfer liquid to switch between the first heat exchange chamber 51 and the second heat exchange chamber.

[0075] Exemplarily, the driving device 7 may include a bidirectional gear pump, a first port of the bidirectional gear pump is connected to the first heat exchange chamber 51, and a second port of the bidirectional gear pump is connected to the second heat exchange chamber, and the bidirectional gear pump is used to switch the heat transfer liquid between the first heat exchange chamber 51 and the second heat exchange chamber.

[0076] Exemplarily, the driving device 7 may include a first water pump and a second water pump, the inlet of the first water pump is connected to the first heat exchange chamber 51, the outlet of the first water pump is connected to the second heat exchange chamber, the inlet of the second water pump is connected to the second heat exchange chamber, and the outlet of the second water pump is connected to the first heat exchange chamber 51. The cooperation of the first water pump and the second water pump enables the heat-conducting liquid to switch between the first heat exchange chamber 51 and the second heat exchange chamber.

[0077] Through the above-mentioned arrangement, when the air conditioner 10 is heating, the driving component can drive the heat-conducting liquid to switch to the first heat exchange chamber 51, and when the air conditioner 10 is cooling, the driving component can drive the heat-conducting liquid to switch to the second heat exchange chamber, so that when the air conditioner 10 is heating, the heat generated by the compressor 1 is used to heat the refrigerant in the gas-liquid separator 2, and when the air conditioner 10 is cooling, the compressor 1 is dissipated to improve the heating effect of the air conditioner 10 and ensure the normal operation of the compressor 1.

[0078] On this basis, in some embodiments, along the arrangement direction of the compressor 1 and the gas-liquid separator 2, the first heat exchange chamber 51 penetrates the first heat exchange shell 5, and the compressor 1 and the gas-liquid separator 2 respectively block the two end openings of the first heat exchange chamber 51.

[0079] Through the above-mentioned arrangement, when the air conditioner 10 is heating, since the compressor 1 and the gas-liquid separator 2 respectively block the two end openings of the first heat exchange chamber 51, the heat-conducting liquid can contact the compressor 1 and the gas-liquid separator 2 at the same time, and the heat generated by the compressor 1 when working can be directly conducted to the heat-conducting liquid, and the heat in the heat-conducting liquid can be directly conducted to the gas-liquid separator 2.

[0080] In this way, the setting of the first heat exchange chamber 51 can accelerate the rate of heat conduction from the compressor 1 to the gas-liquid separator 2 and reduce the heat loss during the conduction process, thereby increasing the amount of heat conducted from the compressor 1 to the gas-liquid separator 2 and improving the heating effect of the air conditioner 10.

[0081] In some examples, the first heat exchange shell 5 is made of an insulating material such as polyurethane, aerogel, etc., which can reduce the amount of heat dissipated from the heat-conducting liquid in the first heat exchange chamber 51 to the air when the air conditioner 10 is heating, and can prevent the heat generated by the compressor 1 from being conducted to the gas-liquid separator 2 through the first heat exchange shell 5 when the air conditioner 10 is cooling, so as to further improve the heating effect of the air conditioner 10 and further ensure the normal operation of the compressor 1.

[0082] In some examples, the second heat exchange shell 6 is provided with an opening toward the compressor 1 , and the compressor 1 blocks the opening.

[0083] Exemplarily, the compressor casing blocks the opening of the second heat exchange casing 6 .

[0084] In this way, when the air conditioner 10 is in cooling mode, the compressor 1 can directly contact the heat-conducting liquid in the second heat exchange chamber, thereby accelerating the rate at which heat from the compressor 1 is transferred to the heat-conducting liquid and accelerating the heat dissipation of the compressor 1.

[0085] In some examples, the second heat exchange shell 6 is also made of a heat-insulating material.

[0086] In some embodiments, the first heat exchange shell 5 is an integrally formed structure, which can improve the structural strength of the first heat exchange shell 5 .

[0087] In some embodiments, Figure 4 As shown, the first heat exchange shell 5 includes a first annular shell 52 and a second annular shell 53. The gas-liquid separator 2 blocks one end opening of the first annular shell 52. Exemplarily, the casing of the gas-liquid separator blocks one end opening of the first annular shell. The compressor 1 blocks one end opening of the second annular shell 53. Exemplarily, the casing of the compressor 1 blocks one end opening of the second annular shell. The other end opening of the second annular shell 53 is sealed and connected to the other end opening of the first annular shell 52.

[0088] Exemplarily, the shape of the first annular shell 52 may be a circular cylinder, a square cylinder, an irregular shape, etc.

[0089] Exemplarily, the second annular shell 53 may be in the shape of a circular cylinder, a square cylinder, an irregular shape, or the like.

[0090] Exemplarily, the first annular shell 52 may be welded to the gas-liquid separator 2 , or the gas-liquid separator 2 and the first annular shell 52 may be integrally formed.

[0091] For example, the second annular casing 53 may be welded to the compressor 1 , or the compressor 1 and the second annular casing 53 may be integrally formed.

[0092] Through the above arrangement, the first annular shell 52 and the second annular shell 53 can be processed separately, and after the first annular shell 52 is connected to the gas-liquid separator 2, and the second annular shell 53 is connected to the compressor 1, the first annular shell 52 and the second annular shell 53 are connected together. Compared with the first heat exchange shell 5 processed by one-piece molding, the sizes of the first annular shell 52 and the second annular shell 53 are smaller, and the first annular shell 52 and the second annular shell 53 can be processed and installed more easily, thereby facilitating the processing and installation of the first heat exchange shell 5.

[0093] In some embodiments, the other end of the second annular shell 53 is sealed and connected to the other end of the first annular shell 52 by welding, so as to ensure the connection strength between the first annular shell 52 and the second annular shell 53 and the stability of the seal therebetween.

[0094] In some embodiments, Figure 3 , Figure 4 As shown, a first connecting portion 521 is provided at the other end of the first annular shell 52, and a second connecting portion 531 is provided at the other end of the second annular shell 53. The first connecting portion 521 and the second connecting portion 531 are detachably connected.

[0095] The air conditioner 10 further includes a seal 8 , which contacts both the first annular shell 52 and the second annular shell 53 and is used to seal a gap between the other end opening of the first annular shell 52 and the other end opening of the second annular shell 53 .

[0096] Exemplarily, the number of the first connection parts 521 may be one or more, such as two, three, four, etc., and the number of the corresponding second connection parts 531 may be one or more.

[0097] Exemplarily, the first connection portion 521 and the second connection portion 531 may be detachably connected together by means of snap connection, screw connection, riveting, etc.

[0098] Through the above arrangement, the sealing member 8 can prevent the heat-conducting liquid from leaking out of the first heat exchange chamber 51, so as to ensure the heat-conducting effect of the heat-conducting liquid. In addition, compared with the sealing connection of the other end of the second annular shell 53 and the other end of the first annular shell 52 by welding, the detachable connection between the first connecting portion 521 and the second connecting portion 531 can simplify the connection process between the other end of the second annular shell 53 and the other end of the first annular shell 52, thereby facilitating the connection between the first annular shell 52 and the second annular shell 53.

[0099] When the first annular casing 52 or the second annular casing 53 needs to be maintained, the first connecting portion 521 and the second connecting portion 531 can be disassembled to quickly separate the first annular casing 52 and the second annular casing 53 to facilitate maintenance of the first annular casing 52 or the second annular casing 53.

[0100] For example, Figure 4 As shown, the seal 8 may be a sealing ring which abuts between the first annular shell 52 and the second annular shell 53 to seal the gap between the other end opening of the first annular shell 52 and the other end opening of the second annular shell 53 .

[0101] Exemplarily, the seal 8 can be a sealing sleeve, one end of which is sleeved on the other end of the first annular shell 52, and the other end of the sealing sleeve is sleeved on the other end of the second annular shell 53, so as to achieve sealing of the gap between the other end opening of the first annular shell 52 and the other end opening of the second annular shell 53.

[0102] In some examples, such as Figure 4 As shown, the first connecting part 521 includes a first connecting plate 5211, and the first connecting plate 5211 is provided with a first mounting hole. The second connecting part 531 includes a second connecting plate 5311, and the second connecting plate 5311 is provided with a second mounting hole. The shell also includes bolts and nuts. The bolts pass through the first mounting hole and the second mounting hole in sequence and are threadedly connected with the nuts to achieve the connection between the first connecting part 521 and the second connecting part 531.

[0103] Based on the above, in some embodiments, such as Figure 3 , Figure 4 As shown, the air conditioner 10 further includes a first heat sink 9 , which is connected to the compressor 1 and is located in the first heat exchange cavity 51 .

[0104] Exemplarily, the first heat sink 9 may include a metal sheet, a metal rod, etc.

[0105] In some examples, the first heat sink 9 includes heat sink fins.

[0106] Exemplarily, the number of the first heat sinks 9 may be one or more, such as two, three, four, etc.

[0107] Through the above-mentioned arrangement, since the first heat sink 9 is connected to the compressor 1, the heat generated by the compressor 1 when working can be conducted to the first heat sink 9. Since the first heat sink 9 is located in the first heat exchange chamber 51, when the air conditioner 10 is in heating mode, the heat-conducting liquid located in the first heat exchange chamber 51 can contact the first heat sink 9.

[0108] In this way, when the air conditioner 10 is in the heating mode, the heat generated by the compressor 1 during operation can be directly conducted to the heat-conducting liquid through the first heat sink 9. Compared with the heat conduction through the first heat exchange shell 5, the rate at which the heat generated by the compressor 1 during operation is conducted to the heat-conducting liquid can be accelerated. Compared with the direct contact between the heat-conducting liquid and the compressor 1, the heat dissipation area when the heat on the compressor 1 is conducted to the heat-conducting liquid can be increased. Similarly, the rate at which the heat generated by the compressor 1 during operation is conducted to the heat-conducting liquid can be accelerated, thereby further improving the heating effect of the air conditioner 10.

[0109] In some examples, the first heat exchange shell 5 is provided with a connection hole, and the first heat sink 9 passes through the connection hole to extend into the first heat exchange cavity 51 .

[0110] In some examples, along the arrangement direction of the compressor 1 and the gas-liquid separator 2 , the first heat exchange cavity 51 passes through the first heat exchange shell 5 , and at this time, the first heat sink 9 is only connected to the compressor 1 .

[0111] In some embodiments, the air conditioner 10 further includes a second heat sink, which is disposed in the gas-liquid separator 2 and connected to an inner wall surface of the gas-liquid separator 2 facing the compressor 1 .

[0112] Illustratively, along the axial direction of the first heat exchange cavity 51 (or the first annular shell 52 ), the projection of the second heat sink may be entirely located within the projection of the first heat exchange cavity 51 , or may be partially located within the projection of the first heat exchange cavity 51 .

[0113] Exemplarily, the second heat sink may include a metal sheet, a metal rod, etc.

[0114] In some examples, the second heat sink includes heat dissipation fins.

[0115] Exemplarily, the number of the second heat dissipation elements may be one or more, such as two, three, four, etc.

[0116] Through the above-mentioned arrangement, when the air conditioner 10 is in the heating mode, after the heat generated by the compressor 1 during operation is conducted to the gas-liquid separator 2, the heat of the gas-liquid separator 2 can be conducted to the second heat sink. Compared with the refrigerant only contacting the gas-liquid separator 2, the heat dissipation area when the heat on the gas-liquid separator 2 is conducted to the refrigerant can be increased, thereby accelerating the rate at which the heat on the gas-liquid separator 2 is conducted to the refrigerant, accelerating the heating of the refrigerant, and thereby improving the heating effect of the air conditioner 10.

[0117] And because the second heat sink is connected to the inner wall surface of the gas-liquid separator 2 facing the compressor 1, the heat in the heat-conducting liquid can be conducted to the second heat sink more quickly after being conducted to the gas-liquid separator 2, thereby further accelerating the rate at which the heat on the gas-liquid separator 2 is conducted to the refrigerant.

[0118] In some examples, such as Figure 3 , Figure 4 As shown, the air conditioner 10 further includes a third heat sink 101 , which is connected to the outside of the second heat exchange shell 6 .

[0119] In some examples, the third heat dissipation member 101 includes heat dissipation fins.

[0120] Through the above arrangement, when the air conditioner 10 is in cooling mode, the heat transferred from the compressor 1 to the heat-conducting liquid can be transferred to the third heat sink 101 through the second heat exchange shell 6, thereby increasing the heat dissipation area of ​​the compressor 1 to the air, thereby accelerating the heat dissipation of the compressor 1.

[0121] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
