[0029] With the improvement of the quality of life, the independent ice-making function has become one of the needs of car users. Compared with the refrigeration function of the car refrigerator, iced beverages and wines can better meet the needs of users. However, most vehicles do not have an independent ice-making function, and the compressor of the independent ice-making machine has limited cooling capacity and slow ice-making speed, which cannot meet the needs of users.

[0030] The utility model proposes a vehicle thermal management system 100, which aims to enable the vehicle to have an independent ice-making function and to achieve rapid ice-making to meet user needs.

[0031] See also Figure 1In one embodiment of the utility model, the vehicle thermal management system 100 includes a compressor 10, a condenser 20, a vehicle-mounted evaporator 30, a main flow regulating member 40 and an ice-making module 50. The input end of the condenser 20 is connected to the exhaust port 11 of the compressor 10; the vehicle-mounted evaporator 30 connects the output end of the condenser 20 to the return air port 12 of the compressor 10; the main flow regulating member 40 is arranged on the flow path between the condenser 20 and the vehicle-mounted evaporator 30; the ice-making module 50 includes an ice-making evaporator 51 and a water box 52, the ice-making evaporator 51 connects the output end of the main flow regulating member 40 to the return air port 12 of the compressor 10, and the ice-making evaporator 51 is used to cool the water in the water box 52 to make ice.

[0032] In the vehicle thermal management system 100, the exhaust port 11 of the compressor 10, the condenser 20, the main flow regulating member 40, the vehicle evaporator 30, and the return air port 12 of the compressor 10 are interconnected to form a refrigerant circulation loop of the vehicle thermal management system 100. The ice-making evaporator 51 of the ice-making module 50 is connected to the refrigerant circulation loop, so that the refrigerant in the refrigerant circulation loop can flow through the ice-making evaporator 51, so that the ice-making evaporator 51 can cool the water in the water box 52 to make ice. Among them, the ice-making evaporator 51 can be arranged in parallel with the vehicle evaporator 30 in the refrigerant circulation loop, or the ice-making evaporator 51 can also be arranged in series with the vehicle evaporator 30 in the refrigerant circulation loop. The vehicle evaporator 30 can include a single evaporator or multiple evaporators. When the vehicle evaporator 30 includes multiple evaporators, the multiple evaporators can be connected to the refrigerant circulation loop in a series and / or parallel manner. For example, the vehicle evaporator 30 may include at least one of a first evaporator 31 for vehicle air conditioning, a second evaporator 32 for vehicle battery cooling, and a third evaporator 33 for a vehicle refrigerator. Optionally, the condenser 20, the vehicle evaporator 30, and the ice-making evaporator 51 are also provided with fans for accelerating the dissipation of cold or heat. The main flow regulating member 40 includes but is not limited to an electronic expansion valve, a thermal expansion valve, a capillary tube, or other types of throttling components.

[0033] It is understandable that the power of the compressor of a traditional vehicle-mounted ice maker is generally 20W to 30W, and the power of the compressor of some slightly larger vehicle-mounted ice makers can reach 70W to 80W, but overall the power of the compressor of the vehicle-mounted ice maker is not high and the cooling capacity is limited. The power of the compressor 10 of the vehicle thermal management system 100 can generally reach 2KW to 10KW, with higher power and greater cooling capacity. Connecting the ice-making evaporator 51 to the refrigerant circulation loop of the vehicle thermal management system 100 can make full use of the large cooling capacity of the refrigeration cycle of the vehicle thermal management system 100, so that the ice-making module 50 can achieve rapid ice making.

[0034] The technical solution of the utility model is to connect the ice-making evaporator 51 of the ice-making module 50 to the refrigerant circulation loop of the vehicle thermal management system 100. When the vehicle thermal management system 100 is running, the high-temperature and high-pressure gaseous refrigerant discharged from the exhaust port 11 of the compressor 10 first enters the condenser 20 to realize condensation and heat release, and then after throttling and reducing the pressure through the main flow regulating member 40, the low-temperature and low-pressure liquid refrigerant can enter the vehicle evaporator 30 and the ice-making evaporator 51 respectively to realize evaporation and heat absorption, and then the low-temperature and low-pressure gaseous refrigerant flows back to the compressor 10 through the return port 12 of the compressor 10, forming a refrigeration cycle. When the refrigerant flows through the ice-making evaporator 51, it exchanges heat with the water in the water box 52 through the ice-making evaporator 51, so that the water in the water box 52 condenses into ice, thereby realizing the ice-making function. Furthermore, by integrating the ice-making module 50 into the vehicle thermal management system 100, compared with the compressor of a separate vehicle-mounted ice maker, the compressor 10 of the vehicle thermal management system 100 has higher power and greater cooling capacity. This can fully utilize the large cooling capacity of the refrigeration cycle of the vehicle thermal management system 100, so that the ice-making module 50 can make ice quickly to meet user needs.

[0035] like Figure 1 As shown, in one embodiment, the water box 52 is located below the ice-making evaporator 51, and the ice-making evaporator 51 includes an evaporator body and a plurality of bullet heads arranged on the evaporator body, and the bullet heads extend into the water box 52 so that the water in the water box 52 can adhere to the surface of the bullet heads and condense into ice.

[0036] In the present embodiment, the ice-making evaporator 51 can specifically adopt a bullet-shaped ice-making evaporator 51. The evaporator body is connected to the refrigerant circulation loop of the vehicle thermal management system 100. The bullet head connected to the evaporator body extends into the water box 52. When the ice-making evaporator 51 is working, the water in the water box 52 adheres to the surface of the bullet head and condenses into ice, so that ice cubes similar to the shape of a bullet can be made, which is more convenient for users to use. Among them, the number of bullet heads can be designed according to the actual demand for ice making. Optionally, a plurality of bullet heads are provided, so that a plurality of bullet-shaped ice cubes can be made at the same time. Of course, in other embodiments, other forms of ice-making evaporators 51 can also be used, as long as the water in the water box 52 can be condensed into ice.

[0037] like Figure 1 As shown, in one embodiment, the ice-making module 50 also includes a flipping mechanism 53 drivingly connected to the water box 52, and an ice storage box 54 arranged below the water box 52, the tops of the water box 52 and the ice storage box 54 are both open, and the flipping mechanism 53 is used to drive the water box 52 to flip so as to pour the ice in the water box 52 into the ice storage box 54.

[0038] In this embodiment, when making ice, the opening of the water box 52 faces upward, and the ice evaporator 51 can be arranged above the water box 52, and the water in the water box 52 is cooled by the ice evaporator 51 to make ice. When ice making is completed, the water box 52 can be driven to flip downward by the flip mechanism 53, so that the opening of the water box 52 faces downward, so that the ice cubes in the water box 52 can fall into the ice storage box 54 under the action of gravity, and the ice cubes can be stored by the ice storage box 54; then the flip mechanism 53 can drive the ice box to flip upward again to open upward, so as to make ice next time. For example, the flip mechanism may include a rotating shaft and a driving motor, and the water box 52 can be rotatably connected to the body of the ice making module 50 through the rotating shaft, and the driving motor is drivingly connected to the rotating shaft, and the rotating shaft is driven by the driving motor to rotate, so that the flip of the water box 52 can be achieved. Of course, the flip mechanism 53 can also adopt other structures, as long as it can achieve the flipping of the water box 52, which is not specifically limited here.

[0039] like Figure 1 As shown, in one embodiment, the ice storage box 54 is provided with a drain port 541. It is understandable that after ice making is completed, some water may remain in the water box 52. When the turning mechanism 53 drives the water box 52 to turn downward to remove ice, the water in the water box 52 will also enter the ice storage box 54. The water in the ice storage box 54 can be discharged in time through the drain port 541 to prevent the ice in the ice storage box 54 from melting.

[0040] In addition, in order to reduce the melting speed of ice cubes in the ice storage box 54 and avoid condensation on the outer surface of the ice storage box 54, in one embodiment, the ice storage box 54 has a heat preservation layer, so as to keep the ice cubes warm. The heat preservation layer includes but is not limited to being made of foam, heat preservation cotton and other materials.

[0041] In order to ensure sufficient water supply during ice making and achieve continuous ice making, Figure 1 As shown, in one embodiment, the vehicle thermal management system 100 further includes a water supply assembly 60 communicated with the water box 52 , and the water supply assembly 60 is used to supply water into the water box 52 .

[0042] Please continue to refer to Figure 1 Furthermore, in one embodiment, the water supply assembly 60 includes a water storage container 61, a water pipe 62 connecting the water storage container 61 with the water box 52, and a water pump 63 connected to the water pipe 62, wherein the water pump 63 is used to provide power so that the water in the water storage container 61 is transported to the water box 52 via the water pipe 62.

[0043] In this embodiment, when the water pump 63 is working, the water pump 63 pumps the water in the water storage container 61 into the water delivery pipe 62, and then delivers the water to the water box 52 through the water delivery pipe 62 to ensure that the water in the water box 52 is sufficient. Of course, in some embodiments, the water storage container 61 can also be arranged above the water box 52, so that the water in the water storage container 61 can flow into the water box 52 under the action of gravity, thereby eliminating the water pump 63. Specifically, the water storage container 61 can be a water tank or bottled water.

[0044] Optionally, the water supply assembly 60 further includes a flow meter for detecting the flow of the water pump 63, and the thermal management system further includes a timing unit, which is used to obtain the working time of the water pump 63. In this way, the amount of water delivered to the water box 52 by the water supply assembly 60 can be determined by the flow and working time of the water pump 63, so as to ensure that the amount of water in the water box 52 can reach a preset water level each time ice is made, thereby ensuring the consistency of ice making quality. In addition, the timing unit can also be used to obtain the ice making time of the ice making module 50, so as to ensure that the ice making time is equal each time, thereby ensuring the consistency of ice making quality.

[0045] like Figure 1 As shown, in one embodiment, the water supply assembly 60 further includes an air intake filter assembly 64 connected to the water storage container 61, and the air intake filter assembly 64 is used to filter the gas input into the water storage container 61. By filtering impurities in the air through the air intake filter assembly 64, it is possible to prevent impurities from being mixed into the water storage container 61 during the air intake process, so that the air pressure balance in the water storage container 61 is maintained when the water pump 63 absorbs water. It is also possible to prevent impurities in the air from being input into the water box 52 through the water delivery pipe 62, resulting in impurities being mixed into the prepared ice cubes, so as to ensure the quality of the ice cubes. Among them, the air intake filter assembly 64 includes but is not limited to using a filter net, a filter membrane, etc. to achieve air filtration.

[0046] Optionally, the water storage container 61 includes a container body and a cover body disposed on the top of the container body, a water storage cavity is formed in the container body, and one end of the water delivery pipe 62 passes through the cover body and is inserted into the water storage cavity. The air intake filter assembly 64 may specifically include an air intake pipe and a filter element disposed at the air intake end of the air intake pipe, and the air outlet end of the air intake pipe passes through the cover body and is inserted into the water storage cavity.

[0047] In order to achieve rapid ice removal after ice making is completed, Figure 1 As shown, in one embodiment, the vehicle thermal management system 100 also includes a refrigerant delivery pipe 71 and a control valve 72 arranged on the refrigerant delivery pipe 71, one end of the refrigerant delivery pipe 71 is connected to the exhaust port 11 of the compressor 10, and the other end of the refrigerant delivery pipe 71 is connected to the input end of the ice-making evaporator 51, and the control valve 72 is used to open or close the refrigerant delivery pipe 71.

[0048] In this embodiment, a refrigerant delivery pipe 71 is connected between the exhaust port 11 of the compressor 10 and the input end of the ice-making evaporator 51, and a control valve 72 is provided on the condensation delivery pipe. When the ice-making evaporator 51 is making ice normally, the control valve 72 cuts off the refrigerant delivery pipe 71. When ice-making is completed, the control valve 72 conducts the refrigerant delivery pipe 71, so that the high-temperature and high-pressure refrigerant discharged from the exhaust port 11 of the compressor 10 can be directly delivered to the ice-making evaporator 51 via the refrigerant delivery pipe 71. At this time, the ice-making evaporator 51 radiates heat to the surrounding environment to facilitate rapid de-icing. For example, when the ice-making evaporator 51 adopts a bullet-type evaporator, the water in the water box 52 adheres to the bullet-shaped surface of the ice-making evaporator 51 and condenses into ice. After ice-making is completed, the high-temperature and high-pressure refrigerant of the compressor 10 enters the ice-making evaporator 51, so that the ice cubes attached to its surface can quickly fall off into the water box 52. For another example, when the water in the water box 52 condenses into ice directly in the water box 52, the heat emitted by the ice-making evaporator 51 can heat the water box 52 to a certain extent, so that the ice cubes are no longer adhered to the inner wall of the water box 52, so that the ice in the water box 52 can be quickly thawed. Among them, the control valve 72 can be an on-off valve or a flow regulating valve.

[0049] Furthermore, the vehicle thermal management system 100 further includes a check valve 80, which is disposed on the flow path between the output end of the ice-making evaporator 51 and the output end of the vehicle-mounted evaporator 30, and is used to prevent the refrigerant outputted from the ice-making evaporator 51 from flowing back toward the vehicle-mounted evaporator 30. In this way, it is possible to prevent the high-temperature refrigerant in the ice-making evaporator 51 from flowing back into the vehicle-mounted evaporator 30 during the deicing process, thereby affecting the refrigeration effect of the vehicle-mounted evaporator 30.

[0050] Optionally, the vehicle-mounted evaporator 30 includes a first evaporator 31, a second evaporator 32 and a third evaporator 33 arranged in parallel, and a check valve 80 is arranged on the flow path between the output junction of the first evaporator 31, the second evaporator 32 and the third evaporator 33 and the output end of the ice-making evaporator 51, so as to prevent the high-temperature refrigerant of the ice-making evaporator 51 from flowing back into any one of the first evaporator 31, the second evaporator 32 and the third evaporator 33 during the defrosting process.

[0051] Based on the above embodiments, Figure 1 As shown, in one embodiment, a first branch and a second branch are connected in parallel between the output end of the main flow regulating element 40 and the return air port 12 of the compressor 10, and the vehicle-mounted evaporator 30 includes a first evaporator 31 for vehicle air conditioning, the first evaporator 31 is connected in series to the first branch, the ice-making evaporator 51 is connected in series to the second branch, the first branch is provided with a first flow regulating element 41, and the second branch is provided with a second flow regulating element 42.

[0052] In this embodiment, the first evaporator 31 is specifically an air conditioning evaporator to cool the interior space of the vehicle cabin. The exhaust port 11 of the compressor 10, the condenser 20, the main flow regulating member 40, the first evaporator 31, and the return air port 12 of the compressor 10 are connected to form a refrigerant circulation loop of the vehicle air conditioning, and the ice-making evaporator 51 is connected in parallel to the refrigerant circulation loop of the air conditioning, so as to realize rapid ice making by utilizing the large cooling capacity of the air conditioning refrigerant system. The first branch and the second branch are respectively provided with a first flow regulating member 41 and a second flow regulating member 42, so that the refrigerant flow entering the first evaporator 31 and the ice-making evaporator 51 can be controlled respectively to meet different cooling capacity requirements. In addition, in the scenario where ice making is not required, the second branch is turned off by the second flow regulating member 42, so that the refrigerant can be prevented from entering the ice-making machine evaporator, and the first branch is controlled by the first flow regulating member 41 to be turned on, so that the normal operation of the air conditioning system can be ensured, so that the operation of the air conditioning and the ice-making module 50 do not affect each other. In addition, during the process of defrosting after ice making is completed, the control valve 72 controls the refrigerant delivery pipe 71 to be open, and shuts off the second branch through the second flow regulator 42, so as to prevent the low-temperature refrigerant after the pressure reduction by the main flow regulator 40 from entering the ice-making evaporator 51 through the second branch and affecting the defrosting effect.

[0053] Furthermore, in one embodiment, a third branch connected in parallel with the first branch is connected between the output end of the main flow regulator 40 and the return air port 12 of the compressor 10, and the vehicle-mounted evaporator 30 also includes a second evaporator 32 for cooling the vehicle battery, and the second evaporator 32 is connected in series to the third branch, and the third branch is provided with a third flow regulator 43.

[0054] In this embodiment, the second evaporator 32 is specifically a battery cooling evaporator to cool down the battery of the vehicle to prevent the battery temperature from being too high. The first evaporator 31, the second evaporator 32 and the ice-making evaporator 51 are arranged in parallel so that the three can operate independently. The refrigerant flow entering the second evaporator 32 can be adjusted and controlled by the third flow regulating member 43 to meet the cooling capacity required for battery cooling.

[0055] Furthermore, in one embodiment, a fourth branch connected in parallel with the first branch is connected between the output end of the main flow regulating element 40 and the return air port 12 of the compressor 10, and the vehicle-mounted evaporator 30 also includes a third evaporator 33 for a vehicle-mounted refrigerator, and the third evaporator 33 is connected in series to the fourth branch, and the fourth branch is provided with a fourth flow regulating element 44.

[0056] In this embodiment, the third evaporator 33 is specifically a refrigerator evaporator to cool the vehicle refrigerator, thereby realizing the refrigeration function of the vehicle refrigerator. The first evaporator 31, the third evaporator 33 and the ice-making evaporator 51 are arranged in parallel so that the three can operate independently. The refrigerant flow entering the third evaporator 33 can be adjusted and controlled by the fourth flow regulating member 44 to meet the cooling capacity required by the vehicle refrigerator.

[0057] Alternatively, if Figure 1 As shown, the vehicle-mounted evaporator 30 includes a first evaporator 31, a second evaporator 32 and a third evaporator 33; the first evaporator 31, the second evaporator 32, the third evaporator 33 and the ice-making evaporator 51 are connected in parallel between the output end of the main flow regulating component 40 and the return air port 12 of the compressor 10, and each branch where the evaporator is located is correspondingly provided with a flow regulating component, so that each evaporator can operate independently and can also operate simultaneously with other evaporators, so that the control of the entire vehicle thermal management system 100 is more flexible and can better meet different usage scenarios.

[0058] Optionally, the vehicle thermal management system 100 further includes a temperature detection element 90 , and the temperature detection element 90 is used to detect the temperature of at least one of the first evaporator 31 , the second evaporator 32 , the third evaporator 33 , and the ice-making evaporator 51 .

[0059] In this embodiment, the temperature detection element 90 includes but is not limited to temperature sensing packages, thermocouples, etc. The temperature detection element 90 and each flow regulating component are electrically connected to the control device respectively. When the vehicle thermal management system 100 is in operation, the temperature detection of the corresponding evaporator is realized through the temperature detection element 90. The control device can control each flow regulating component in the vehicle thermal management system 100 in a targeted manner according to the temperature detection signal fed back by the temperature detection element 90, thereby realizing the control of the refrigerant flow through the corresponding evaporator to achieve a better heat exchange effect.

[0060] The following combination Figure 1 , an ice making process in a specific embodiment is illustrated by way of example.

[0061] When the vehicle thermal management system 100 receives a request for ice making and cooling, the water pump 63 of the water supply assembly 60 is started to pump the water in the water storage container 61 into the water box 52, and the amount of water delivered to the water box 52 is determined according to the relationship between the water flow rate and the pumping time to ensure that the water in the water box 52 reaches the preset water level. The second flow regulating member 42 is controlled to conduct the second branch, so that the high-temperature refrigerant discharged from the compressor 10 passes through the condenser 20 and the main flow regulating member 40 and is delivered to the ice-making evaporator 51 through the second branch, and the ice-making evaporator 51 starts to cool the water in the water box 52 to make ice. When ice making reaches a preset time, the second flow regulating member 42 is controlled to shut off the second branch, the control valve 72 turns on the refrigerant delivery pipe 71, and the high-temperature refrigerant discharged from the compressor 10 is directly delivered to the ice-making evaporator 51 through the refrigerant delivery pipe 71 for de-icing. The flip mechanism 53 drives the water box 52 to flip to pour the ice cubes in the water box 52 into the ice storage box 54 for storage, and the excess water is discharged through the drain port 541 of the ice storage box 54 to prevent the ice cubes from melting, thus completing an ice making process. The check valve 80 can prevent the high-temperature refrigerant in the ice-making evaporator 51 from flowing back to the vehicle-mounted evaporator 30 during the de-icing process.
