[0031] Reference below Figure 1-Figure 3 Description According to the vehicle refrigerator 100 of the embodiment of the utility model, by arranging a plurality of evaporation pipes 31 on the outer peripheral wall of the refrigerator inner tank 4, the refrigerator inner tank 4 can be cooled at multiple locations, thereby improving the refrigeration efficiency of the vehicle refrigerator 100 and improving the temperature balance of the refrigerator inner tank 4.

[0032] like Figure 1-Figure 3 As shown, a vehicle refrigerator 100 according to an embodiment of the present utility model includes: a compressor 1, a condenser 2 and an evaporator 3.

[0033] The compressor 1, the condenser 2 and the evaporator 3 are connected in series in sequence to form a heat exchange circuit. Specifically, the compressor 1 is connected to the condenser 2 through a pipeline, the condenser 2 is connected to the evaporator 3 through a pipeline, and the evaporator 3 is connected to the compressor 1 through a pipeline. The compressor 1, the condenser 2 and the evaporator 3 can be connected in series in sequence to form a complete heat exchange circuit, and the heat exchange circuit exchanges heat with the refrigerator inner tank 4 to achieve refrigeration of the refrigerator inner tank 4.

[0034] Among them, the evaporator 3 includes a plurality of evaporation pipes 31, which are installed on the outer peripheral wall of the refrigerator inner tank 4, and the plurality of evaporation pipes 31 are connected in parallel between the condenser 2 and the compressor 1. That is to say, at the evaporator 3, heat is exchanged with the refrigerator inner tank 4 through the plurality of evaporation pipes 31 to achieve cooling of the refrigerator inner tank 4.

[0035] Specifically, the evaporator 3 is arranged outside the refrigerator inner tank 4. The evaporator 3 includes a plurality of evaporation pipelines 31. The plurality of evaporation pipelines 31 can be fixedly installed on the outer peripheral wall of the refrigerator inner tank 4. For example, the plurality of evaporation pipelines 31 can be arranged around the outer periphery of the refrigerator inner tank 4, or can be arranged on part of the outer peripheral wall of the refrigerator inner tank 4. Both of these settings can meet the layout requirements of the plurality of evaporation pipelines 31, and can be flexibly selected according to the actual space and pipeline setting requirements.

[0036] like Figure 1As shown, the compressor 1 is arranged between the condenser 2 and the evaporator 3, and the compressor 1, the condenser 2 and the evaporator 3 are connected in series in sequence to form a refrigeration circuit, and a plurality of evaporation pipes 31 are distributed in parallel on the outer peripheral wall of the refrigerator inner tank 4. In this way, the outer peripheral wall of the refrigerator inner tank 4 can be quickly cooled by the compressor 1 and the condenser 2 exchanging heat with the plurality of evaporation pipes 31 at the same time.

[0037] In addition, the cavity of the refrigerator liner 4 is a storage room for placing water, beverages, food, etc., wherein the refrigerant can be R134a. When the vehicle refrigerator 100 needs to be used, first, the user needs to input a refrigeration temperature, and then the compressor 1 compresses the refrigerant and transports the compressed high-temperature and high-pressure refrigerant to the condenser 2. The condenser 2 is connected to a heat dissipation fan 21. The heat dissipation fan 21 works to dissipate part of the heat of the high-temperature and high-pressure refrigerant, and then transports the refrigerant to multiple evaporation pipelines 31. The evaporation of the refrigerant will absorb the heat of the refrigerator liner 4 to achieve the refrigeration of the refrigerator liner 4, and the refrigerant flows back to the compressor 1 to continue the gas compression and refrigeration cycle until the temperature of the refrigerator liner 4 drops to the set temperature, and the compressor 1 stops working to end the refrigeration cycle. At this time, the refrigerator liner 4 is in a heat preservation condition to achieve the refrigeration function; with the use of the vehicle refrigerator 100, when the temperature at the refrigerator liner 4 rises, the compressor 1 works again to reduce the temperature of the refrigerator liner 4, so that the continuous refrigeration of the vehicle refrigerator 100 is achieved.

[0038] Therefore, by arranging multiple evaporation pipes 31 in parallel, the outer wall of the refrigerator inner tank 4 and the multiple evaporation pipes 31 can exchange heat simultaneously, which can accelerate the refrigeration speed of the refrigerator inner tank 4. During the refrigeration process, the temperature difference between the multiple side walls of the refrigerator inner tank 4 is small, making the temperature more uniform, thereby improving the refrigeration effect of the vehicle refrigerator 100 and meeting the refrigeration needs.

[0039] According to the vehicle refrigerator 100 of the embodiment of the utility model, by arranging multiple evaporation pipelines 31 in parallel between the condenser 2 and the compressor 1, multiple evaporation pipelines 31 can simultaneously cool the outer peripheral wall of the refrigerator inner tank 4, so that the cooling speed of various parts of the refrigerator inner tank 4 is accelerated and the temperature is more uniform, thereby improving the refrigeration efficiency and enhancing the user experience.

[0040] In some embodiments, a first connecting pipeline 5 is connected between the evaporator 3 and the condenser 2 , and the first connecting pipeline 5 includes a main pipeline 51 and a multi-component pipeline 52 , one end of the main pipeline 51 is connected to the outlet end of the condenser 2 and the other end is connected to the multi-component pipeline 52 .

[0041] Specifically, the first connecting pipeline 5 is used to connect the condenser 2 and the evaporator 3. The first connecting pipeline 5 can be arranged outside the pipeline connecting the evaporator 3 and the compressor 1 to achieve the fixation of the first connecting pipeline 5. The first connecting pipeline 5 includes two parts of pipelines, namely a main pipeline 51 and a multi-component pipeline 52. The main pipeline 51 is connected to the multi-component pipeline 52. Specifically, one end of the main pipeline 51 is connected to the outlet end of the condenser 2, and the other end is connected to the multi-component pipeline 52. The outlet end of the multi-component pipeline 52 is respectively connected to multiple evaporation pipelines 31, wherein the main pipeline 51 and the multi-component pipeline 52 have the same diameter, the length of the main pipeline 51 is greater than the length of the multi-component pipeline 52, and the main pipeline 51 on the side close to the evaporator 3 is connected to the multi-component pipeline 52, so that the refrigerant in the condenser 2 can be transported to the evaporator 3 through the multi-component pipeline 52.

[0042] Among them, evaporation pipelines 31 are provided on multiple sides of the refrigerator inner tank 4, and the multi-component pipelines 52 are connected to the evaporation pipelines 31 on multiple sides respectively. In this way, the multi-component pipelines 52 are connected to the evaporation pipelines 31 on multiple sides of the refrigerator inner tank 4 correspondingly, and the refrigerant can be transported to multiple sides of the refrigerator inner tank 4, and evaporation and heat absorption are carried out simultaneously on multiple sides, thereby realizing synchronous cooling of multiple sides.

[0043] Specifically, the refrigerator liner 4 has a square shape, and the refrigerator liner 4 is formed with an installation cavity open upward, which can be used to place items. The outer periphery of the refrigerator liner 4 includes multiple side surfaces, and the multiple side surfaces are provided with evaporation pipelines 31. The multi-component pipelines 52 are respectively connected to the evaporation pipelines 31 on the multiple side surfaces in a one-to-one correspondence, wherein, Figure 3 As shown, the branch pipelines 52 can be three groups, and the three groups of pipelines 52 are connected to the evaporation pipelines 31 on three sides of the refrigerator inner tank 4 one by one, and the refrigerant evaporates and absorbs heat when entering the evaporation pipeline 31, so that when the refrigerant enters the evaporation pipelines 31 on three sides of the refrigerator inner tank 4 at the same time, the three sides can be cooled at the same time, reducing the refrigeration delay and improving the refrigeration efficiency. In addition, the number of branch pipelines 52 is not limited to that described in this embodiment, and can be set according to actual needs.

[0044] Therefore, by branching the main line 51 and connecting it to multiple side evaporation lines 31, the refrigerant can be input into the evaporator 3 in parallel. Compared with series input, the number of refrigerant input points is increased, thereby achieving multiple refrigeration of the refrigerator inner tank 4 and a better refrigeration effect.

[0045] In some embodiments, each group of pipelines 52 includes a first branch 521 and multiple second branches 522, one end of the first branch 521 is connected to the main pipeline 51 and the other end is connected to the multiple second branches 522. Specifically, the branch pipeline 52 includes two parts of pipelines 52, namely the first branch 521 and the multiple second branches 522, the first branch 521 is connected to the multiple second branches 522, specifically, one end of the first branch 521 is connected to the main pipeline 51, and the other end is connected to the multiple second branches 522, that is, the branch pipeline 52 is branched, and the outlet ends of the multiple second branches 522 are respectively connected to the multiple evaporation pipelines 31, and the first branch 521 on the side close to the evaporation pipeline 31 is connected to the multiple second branches 522. In this way, the refrigerant can be divided from the first branch 521 into multiple paths and transported to the evaporator 3.

[0046] A plurality of evaporation pipes 31 are disposed on each side of the refrigerator inner container 4, and the plurality of second branches 522 are connected to the plurality of evaporation pipes 31 on the corresponding side in a one-to-one correspondence.

[0047] Specifically, a plurality of evaporation pipes 31 are provided on each side of the refrigerator inner tank 4, and the area of ​​each side may be the same or different, that is, the number of evaporation pipes 31 on each side may be the same or different, and the number of second branches 522 is correspondingly set to be the same or different. The plurality of second branches 522 are respectively connected to the plurality of evaporation pipes 31 on the corresponding sides in a one-to-one correspondence, and the refrigerant can be transported to multiple positions on one side, and evaporate and absorb heat at the multiple positions at the same time, thereby realizing synchronous refrigeration of multiple positions on multiple sides, which can speed up the refrigeration efficiency of each side, and the three sides are cooled at the same time, which can improve the refrigeration efficiency of the refrigerator inner tank 4.

[0048] Therefore, by branching and re-branching the main line 51, the first connecting line 5 is connected in parallel to the evaporating line 31, increasing the input points of the refrigerant on different sides, thereby achieving refrigeration at multiple locations on the corresponding sides of the refrigerator inner tank 4, and achieving a better refrigeration effect.

[0049] In some embodiments, the evaporation pipeline 31 includes a connected collecting main pipeline 311 and a connecting branch 312, the collecting main pipeline 311 of multiple evaporation pipelines 31 is connected, and the connecting branches 312 of multiple evaporation pipelines 31 are respectively connected to the multi-component pipeline 52, and the collecting main pipeline 311 is connected to the inlet end of the compressor 1.

[0050] Specifically, the evaporation pipeline 31 includes two parts of pipelines 52, namely a collecting main pipeline 311 and a connecting branch 312, and the connecting branch 312 is connected to the collecting main pipeline 311, wherein one end of the connecting branch 312 of the plurality of evaporation pipelines 31 is respectively connected to the multi-component pipeline 52, and the other end is connected to the collecting main pipeline 311, and the collecting main pipelines 311 of the plurality of evaporation pipelines 31 are connected to each other, such as Figure 1 and Figure 2 As shown, the converging main paths 311 of multiple evaporation pipelines 31 on different sides of the refrigerator inner tank 4 are connected in sequence, and the outlet end of the converging main path 311 on one side is connected to the inlet end of the compressor 1 to achieve the reflux of the refrigerant.

[0051] Therefore, after the refrigerant enters the connecting branch 312, it evaporates and absorbs heat, realizing heat exchange with the refrigerator inner tank 4. In the refrigeration process, the refrigerants of multiple connecting branches 312 flow into the collecting main path 311 respectively, and flow back to the compressor 1 through the collecting main path 311 to enter the next refrigeration cycle, realizing continuous refrigeration.

[0052] In some embodiments, the connecting branch 312 is arranged to extend vertically, and multiple groups of connecting branches 312 are distributed in a spaced-apart manner in the horizontal direction. The collecting main road 311 of multiple evaporation pipelines 31 is connected in the horizontal direction, and the upper end of the connecting branch 312 is connected to the branch pipeline 52 and the lower end is connected to the collecting main road 311.

[0053] Specifically, the connecting branch 312 and the collecting main road 311 extend in different directions, such as Figure 1 and Figure 2 As shown, the connecting branch 312 is set to extend vertically, and the collecting main road 311 is set to extend horizontally, that is, the shape of the evaporation pipeline 31 can be set to an L-type or T-type pipeline, wherein the upper end of the connecting branch 312 is connected to the second branch 522 of the branch road 52, and the lower end is connected to the collecting main road 311, and multiple groups of connecting branches 312 are spaced apart and distributed in the horizontal direction, and the intervals are the same, and multiple evaporation pipelines 31 are connected in the horizontal direction through the collecting main road 311, and the horizontal direction includes the front-back direction and the left-right direction, that is, the extension direction of the collecting main road 311 on different sides of the refrigerator inner tank 4 is parallel or vertical.

[0054] Therefore, by distributing the connecting branches 312 at intervals, the connecting branches 312 can be distributed on each side of the refrigerator inner tank 4, so that each side can be quickly cooled, the refrigeration effect of the refrigerator inner tank 4 can be improved, and the temperature difference between different sides can be reduced, thereby improving temperature balance.

[0055] In some embodiments, the plurality of sides include a first side 41 and a second side 42 , where the first side 41 and the second side 42 are two oppositely distributed sides of the refrigerator inner tank 4 , and each of the first side 41 and the second side 42 is provided with at least one evaporation pipeline 31 .

[0056] Specifically, the plurality of side surfaces may include two oppositely distributed first side surfaces 41 and second side surfaces 42, wherein the first side surfaces 41 and the second side surfaces 42 are connected via a third side surface 43 and a fourth side surface. Figure 1 and Figure 2As shown, evaporation pipelines 31 are provided on three of the side surfaces of the refrigerator inner tank 4, and at least one evaporation pipeline 31 may be provided on each of the first side surface 41 and the second side surface 42. The number of evaporation pipelines 31 on the first side surface 41 and the second side surface 42 may be set to five, and the connecting branches 312 of the five evaporation pipelines 31 are spaced apart and distributed along the front-to-back direction. Correspondingly, the number of the second branches 522 is also five, and the converging main roads 311 of the five evaporation pipelines 31 extend along the front-to-back direction. The evaporation pipeline 31 on one side surface between the first side surface 41 and the second side surface 42 is set to three, and the connecting branches 312 of the three evaporation pipelines 31 are spaced apart and distributed along the left-to-right direction. Correspondingly, the number of the second branches 522 is also three, and the converging main roads 311 of the three evaporation pipelines 31 extend along the left-to-right direction. Figure 2 As shown, the front end pipeline of the main converging path 311 on the second side 42 is connected to the inlet end of the compressor 1. With this arrangement, the overall evaporation pipeline 31 is clearly and neatly arranged, and multiple locations of the refrigerator inner tank 4 can be cooled.

[0057] The number of the evaporation pipelines 31 and the second branches 522 on the three sides is not limited to that described in the present embodiment, and can be flexibly set according to specific design requirements.

[0058] In some embodiments, the first side surface 41 and the second side surface 42 are opposite to each other along a first direction, and the evaporation lines 31 on the first side surface 41 and the evaporation lines 31 on the second side surface 42 are opposite to each other along the first direction.

[0059] Specifically, the vehicle refrigerator 100 of the utility model can be installed in the space between two rear seats, and the vehicle refrigerator 100 can be integrated with the vehicle body. The first side surface 41 and the second side surface 42 of the refrigerator liner 4 can be relatively distributed along the front-to-back direction or the left-to-right direction, such as Figure 1 and Figure 2 As shown, in this embodiment, the first direction can be the left-right direction, the first side 41 is the left side, the second side 42 is the right side, the third side 43 is the rear side, and the fourth side is the front side, wherein the evaporation pipeline 31 is arranged on the left side, rear side and right side of the refrigerator liner 4, the first side 41 and the second side 42 have the same area, and the third side 43 and the fourth side have the same area, so that the evaporation pipeline 31 of the first side 41 and the evaporation pipeline 31 of the second side 42 are arranged opposite to each other along the left-right direction, and the arrangement is regular and simple, which simplifies the arrangement cost and reduces the assembly cost, and can realize synchronous refrigeration on the first side 41 and the second side 42, and the refrigeration capacity of the two sides is close to the same, which reduces the temperature difference between the two sides. Among them, the refrigerator controller can be installed on the front side of the fourth side, and the refrigerator controller is used to receive and send control signals to control the operation of the vehicle refrigerator 100.

[0060] During the cooling process, the refrigerant on the left side and the rear side flows into the right side of the main collecting path 311 through the main collecting path 311 of the evaporation pipeline 31 , and then flows back into the compressor 1 .

[0061] In some embodiments, the flow cross-sectional area of ​​the evaporation pipeline 31 is larger than the flow cross-sectional area of ​​the first connecting pipeline 5. In this way, when the refrigerant flows from the first connecting pipeline 5 into the evaporation pipeline 31, the flow cross-sectional area of ​​the refrigerant changes suddenly, and the refrigerant absorbs heat and evaporates to realize the refrigeration effect of the evaporator 3.

[0062] Among them, Figure 3 As shown, the first connecting pipe 5 can be constructed as a capillary tube, the flow cross-sectional area of ​​the capillary tube is small, the flow cross-sectional area of ​​the evaporation pipe 31 is large, and the flow cross-sectional area of ​​the two is very different, so that the flow cross-sectional area suddenly increases when the refrigerant enters the evaporation pipe 31 from the capillary tube. At this time, the refrigerant absorbs heat and evaporates into gas, which can take away the heat of the refrigerator inner tank 4, thereby realizing the cooling of the refrigerator inner tank 4.

[0063] In some embodiments, a second connecting pipeline 6 is connected between the compressor 1 and the condenser 2 , and a flow cross-sectional area of ​​the second connecting pipeline 6 is greater than a flow cross-sectional area of ​​the first connecting pipeline 5 .

[0064] Specifically, the second connecting pipeline 6 is used to connect the compressor 1 and the condenser 2. The compressor 1 is provided with an air inlet and an air outlet. The air outlet is connected to the second connecting pipeline 6, and the air inlet is connected to the evaporation pipeline 31. The flow cross-sectional area of ​​the second connecting pipeline 6 is larger than the flow cross-sectional area of ​​the first connecting pipeline 5, and a dryer 9 is provided between the first connecting pipeline 5 and the condenser 2. One end of the dryer 9 is connected to the heat exchange pipeline of the condenser 2, and the other end is connected to the first connecting pipeline 5. In this way, the high-temperature and high-pressure gas in the compressor 1 can be transported to the condenser 2 through the second connecting pipeline 6 for cooling, and then the water vapor in the refrigerant is removed by the dryer 9. The dried refrigerant enters the capillary tube, reducing the flow cross-sectional area of ​​the refrigerant. The flow cross-sectional area of ​​the evaporation pipeline 31 is larger than the flow cross-sectional area of ​​the second connecting pipeline 6, which can expand the cross-sectional area difference between the first connecting pipeline 5 and the evaporation pipeline 31, which is beneficial for the refrigerant to flow into the evaporation pipeline 31 to achieve a sudden change in cross-sectional area, so as to realize the refrigeration of the evaporator 3.

[0065] It should be noted that the vehicle refrigerator 100 is also provided with a compressor controller 7 for controlling the working state of the compressor 1. The compressor controller 7 is provided between the compressor 1 and the condenser 2. The compressor controller 7 is electrically connected to the compressor 1 and the cooling fan 21, and can control the operation of the compressor 1 and the cooling fan 21 respectively. After receiving the refrigeration instruction from the refrigerator controller, the compressor controller 7 controls the compressor 1 to work, starts to compress the refrigerant, and controls the cooling fan 21 to rotate, blows away part of the heat of the refrigerant in the condenser 2, and realizes the cooling of the refrigerant. After the refrigerator liner 4 meets the refrigeration demand, the compressor controller 7 controls the compressor 1 to stop working, and the intelligent refrigeration of the vehicle refrigerator 100 can be realized. An upper trim plate 8 is installed on the upper side of the refrigerator liner 4, and a storage area is provided in the upper trim plate 8 for storing items. The rear side of the upper trim plate 8 is movably connected to the refrigerator cover plate, and the connection method can be a hinge or the like. In this way, when the vehicle refrigerator 100 needs to be used, the refrigerator cover plate is rotated back relative to the upper trim plate 8 to open, and the food or items to be refrigerated can be placed.

[0066] The utility model also provides a vehicle.

[0067] According to the vehicle of the embodiment of the utility model, a vehicle refrigerator 100 according to any one of the above embodiments is provided. By arranging a plurality of evaporation pipes 31 in parallel between the condenser 2 and the compressor 1, the plurality of evaporation pipes 31 can simultaneously cool the outer peripheral wall of the refrigerator inner tank 4, so that the cooling speed of various parts of the refrigerator inner tank 4 is accelerated and the temperature is more uniform, thereby improving the refrigeration efficiency and enhancing the user experience.
