In the description of the embodiments of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly specified.

[0026] The present application provides a vehicle-mounted refrigerator 100 in one aspect, please refer to Figures 1 to 3 The vehicle-mounted refrigerator 100 includes a storage device 1 and a heat exchange device 2. The storage device 1 includes a shell 11 and a storage shell 12, the shell 11 is formed with a placement cavity 11a, and the storage shell 12 is arranged in the placement cavity 11a. The heat exchange device 2 includes an air cooling assembly 21 and a cold storage assembly 22, the air cooling assembly 21 includes an air cooling shell 211, a fin 212 and a fan 213, the air cooling shell 211 is connected between the cold storage assembly 22 and the shell 11, the air cooling shell 211 is formed with a containing cavity 211a, an air inlet 211b and an air outlet 211c, the containing cavity 211a communicates with the air inlet 211b and the air outlet 211c, the air inlet 211b and the air outlet 211c both communicate with the placement cavity 11a, the fin 212 is arranged in the containing cavity 211a, the fan 213 is arranged in the air inlet 211b and / or the air outlet 211c, and the cold storage assembly 22 is in air flow heat exchange with the containing cavity 211a through the fin 212.

[0027] Exemplarily, the fan 213 is arranged at the air inlet 211b and / or the air outlet 211c, which means that when the number of the fan 213 is one, the fan 213 can be arranged at the air inlet 211b or the air outlet 211c, and when the number of the fan 213 is more than one, the fan 213 can be arranged at both the air inlet 211b and the air outlet 211c.

[0028] Here, by arranging the storage shell 12 in the placing cavity 11a, the shell 11 can protect the storage shell 12 to a certain extent and reduce the loss of cold energy, thereby improving the heat preservation efficiency.

[0029] The vehicle-mounted refrigerator 100 provided by the embodiment of the present application has the following advantages. The air-cooled shell 211 is connected between the cold storage assembly 22 and the shell 11, the air-cooled shell 211 is formed with an air inlet 211b, an air outlet 211c and a containing cavity 211a, the containing cavity 211a is communicated with the air inlet 211b and the air outlet 211c, the air inlet 211b and the air outlet 211c are both communicated with the placing cavity 11a, and the fan 213 is arranged at the air inlet 211b and / or the air outlet 211c. In this way, by driving the fan 213, the air flow to be heat exchanged in the placing cavity 11a can enter the containing cavity 211a from the air inlet 211b, and then be heat exchanged with the fins 212 in the containing cavity 211a. The air flow after heat exchange can flow out from the air outlet 211c and be heat exchanged with the storage shell 12. On the one hand, the fins 212 can increase the heat exchange area with the air flow to be heat exchanged, thereby improving the heat exchange effect, and the air-cooled shell 211 can protect the fins 212 to a certain extent and reduce the loss of cold energy in the containing cavity 211a, thereby further improving the heat exchange effect. On the other hand, the air-cooled shell 211 is connected between the cold storage assembly 22 and the shell 11, that is, the heat exchange between the air flow to be heat exchanged and the cold storage assembly 22 is performed in the containing cavity 211a outside the placing cavity 11a. In this way, the effective volume of the storage shell 12 can be effectively increased, and the storage shell 12 and the cold storage assembly 22 can be effectively isolated, thereby reducing the influence of the heat generated by the cold storage assembly 22 and the like on the storage shell 12.

[0030] Exemplarily, in an embodiment, the first direction can be the front-rear direction of the vehicle, the second direction can be one of the up-down direction and the left-right direction of the vehicle, such as the up-down direction, and the third direction can be the other one of the up-down direction and the left-right direction of the vehicle.

[0031] It should be noted that up refers to the direction toward the roof, and down is opposite to up. The up-down direction, the front-rear direction and the left-right direction can be perpendicular to each other to jointly constitute a three-dimensional perpendicular coordinate system.

[0032] Exemplarily, in an embodiment, Figure 1 R1 in the first direction, R2 in the second direction, and R3 in the third direction.

[0033] In an example, the fan 213 can be an axial fan. In this way, the high flow output of the air flow can be improved to accelerate the forced convection heat exchange, and the refrigeration rate is fast.

[0034] In an example, referring to Figure 1 and Figure 2 , the arrangement direction of the storage device 1, the cold storage assembly 22 and the air-cooled assembly 21 is the first direction, the cavity wall of the housing 11 close to the cavity 211a along the first direction is the air exchange wall 211d, and the air inlet 211b and the air outlet 211c are located on the two side edges of the air exchange wall 211d along the second direction, wherein the first direction intersects the second direction.

[0035] In an example, the housing 11 is formed with a connecting port 11b communicated with the placing cavity 11a at one end along the first direction, the air-cooled shell 211 can include a ring shell 2111 and a cover plate 2112, the ring shell 2111 is formed with the containing cavity 211a, the containing cavity 211a penetrates through one side of the ring shell 2111 along the first direction to form a penetration port, the cover plate 2112 is connected to the periphery of the connecting port 11b at one end along the first direction, and the cover plate 2112 is covered on the penetration port at the other end along the first direction. One end of the cold storage assembly 22 along the first direction is connected to one end of the ring shell 2111 relative to the penetration port, and the area of the containing cavity 211a projected on the cover plate 2112 along the first direction can be the air exchange wall 211d.

[0036] Here, by setting the air inlet 211b and the air outlet 211c on the two side edges of the air exchange wall 211d along the second direction, the air flow to be exchanged out of the placing cavity 11a can enter the containing cavity 211a from the air inlet 211b on the air exchange wall 211d along the first direction, and then exchange heat with the fins 212. The air flow after heat exchange can flow back to the placing cavity 11a from the air outlet 211c on the air exchange wall 211d and exchange heat with the storage shell 12. Since the air inlet 211b and the air outlet 211c are located on the two side edges of the air exchange wall 211d along the second direction, the heat exchange path of the air flow to be exchanged along the second direction can be extended, and the heat exchange effect can be improved.

[0037] In an example, referring to Figure 3 , the fins 212 can include a plurality of heat exchange fins 2121, and the heat exchange fins 2121 are arranged along the second direction. The plurality of heat exchange fins 2121 can be arranged at intervals along the third direction, so that two adjacent heat exchange fins 2121 define a heat dissipation channel extending along the second direction between them along the third direction, and the heat dissipation channel communicates the air inlet 211b and the air outlet 211c.

[0038] In an example, referring to Figure 1In an embodiment, the storage shell 12 can be a drawer, the top of the storage shell 12 has an opening 12a, the opening 12a is in communication with the placing cavity 11a, the shell 11 forms a taking and placing opening relative to the connecting opening 11b along the first direction, the taking and placing opening is in communication with the placing cavity 11a, the storage shell 12 can be slidably arranged in the placing cavity 11a through the slide rail and the slide block, when it is needed to place and / or take the articles, the storage shell 12 can be pulled out from the taking and placing opening, then the articles can be taken and / or placed from the opening 12a, after the placing and / or taking of the articles is completed, the storage shell 12 can be pushed into the placing cavity 11a from the taking and placing opening.

[0039] In an embodiment, the second direction is the up-down direction of the vehicle, the air inlet 211b is located at the lower side edge of the air exchange wall 211d, and the air outlet 211c is located at the upper side edge of the air exchange wall 211d.

[0040] In this way, the to-be-exchanged heat flow can enter the containing cavity 211a from the air inlet 211b at the lower side edge of the air exchange wall 211d, and can flow back to the placing cavity 11a from the air outlet 211c at the upper side edge after heat exchange with the fins 212, since the articles are generally placed below the storage shell 12, at this time, the heat-exchanged air flow (cold air) can naturally sink to better exchange heat with the articles in the storage shell 12, and the air outlet from the upper side can also reduce the situation of being blocked by the articles in the storage shell 12.

[0041] In an embodiment, please refer to Figure 1 A part of the fins 212 is located between the air inlet 211b and the air outlet 211c, and another part of the fins 212 shields the air inlet 211b along the first direction.

[0042] In this way, after entering from the air inlet 211b, the to-be-exchanged heat flow can directly exchange heat with the fins 212 to further prolong the flow path of the to-be-exchanged heat flow and improve the heat exchange effect.

[0043] In an embodiment, please refer to Figure 1 The heat exchange device 2 includes a temperature sensor 23 arranged at the air outlet 211c to monitor the temperature of the air outlet 211c.

[0044] In an embodiment, the circumferential side of the fin 212 abuts against the corresponding cavity wall of the containing cavity 211a.

[0045] In an embodiment, the side along the first direction, the side along the second direction, and the side along the third direction of the fin 212 can abut against the corresponding cavity wall of the containing cavity 211a. In this way, the to-be-exchanged heat flow can be prevented from flowing from the gap between the fin 212 and the cavity wall of the containing cavity 211a to the air outlet 211c, so that the to-be-exchanged heat flow flows out of the placing cavity 11a through the fin 212 and then flows out of the air outlet 211c, which can further improve the heat exchange effect of the to-be-exchanged heat flow.

[0046] In an embodiment, referring to Figure 1 , the number of fins 212 is multiple, and the multiple fins 212 are arranged at intervals along the arrangement direction of the air inlet 211b and the air outlet 211c.

[0047] For example, the number of fins 212 can be two, and the two fins 212 can be arranged at intervals along the second direction.

[0048] Here, by arranging multiple fins 212 at intervals along the arrangement direction of the air inlet 211b and the air outlet 211c, the flow of the air to be heated will form a turbulent flow when passing through the intervals, so that the heat exchange time of the air to be heated with the fins 212 and the heat exchange path of the air to be heated can be prolonged, and the heat exchange effect is better.

[0049] In an embodiment, referring to Figure 3 , the fin 212 has a turbulent groove 212a, and the extension direction of the turbulent groove 212a intersects the arrangement direction of the air inlet 211b and the air outlet 211c.

[0050] For example, the fin 212 has a turbulent groove 212a extending along the third direction in the middle along the second direction, so that the flow of the air to be heated will form a turbulent flow when passing through the turbulent groove 212a, so that the heat exchange time of the air to be heated with the fin 212 and the heat exchange path of the air to be heated can be prolonged, and the heat exchange effect is better.

[0051] For example, in an embodiment, the number of turbulent grooves 212a can be multiple, for example, two or more, to further improve the heat exchange effect. It should be noted that the number of turbulent grooves 212a cannot be too many, and too many can cause the heat exchange area of the fin 212 to decrease.

[0052] For example, in an embodiment, referring to Figures 1 to 3 , the number of air inlets 211b, air outlets 211c and fans 213 can be multiple, for example, the number of air inlets 211b, air outlets 211c and fans 213 can be four, and the four air inlets 211b, four air outlets 211c and four fans 213 can be arranged at intervals along the third direction, so that the air inlet amount and the air supply amount can be increased, and the heat exchange efficiency is higher.

[0053] In an embodiment, referring to Figure 1 and Figure 2The end surface of the air-cooled shell 211 relative to the air inlet 211b and the air outlet 211c is provided with a communication port 211e, and the communication port 211e communicates with the accommodating cavity 211a. The cold storage assembly 22 comprises a heat conduction plate 221, a cold storage shell 222, a phase change material, and an evaporator 223. The cold storage shell 222 is provided with a mounting port 222a which communicates with the internal space of the cold storage shell 222. The evaporator 223 and the phase change material are arranged in the cold storage shell 222. One end of the heat conduction plate 221 is arranged on the communication port 211e, and the other end of the heat conduction plate 221 is arranged on the mounting port 222a. The fin 212 is arranged on the heat conduction plate 221.

[0054] For example, the ring shell 2111 is provided with a communication port 211e relative to the end surface of the through port in the first direction. The phase change material can be water.

[0055] Here, by arranging the evaporator 223, the phase change material, the cold storage shell 222, and the heat conduction plate 221, the evaporator 223 can perform refrigeration, the cold storage shell 222 can insulate its internal space to a certain extent to reduce the loss of cold energy, and the phase change material arranged in the cold storage shell 222 can store a certain amount of cold energy for subsequent cold release. The released cold energy can be transmitted to the fin 212 through the heat conduction plate 221 to exchange heat with the airflow to be exchanged. Here, the transmission of cold energy through the heat conduction plate 221 can further improve the refrigeration rate and refrigeration effect.

[0056] For example, in an embodiment, the heat conduction plate 221 can be a metal plate. In this way, the heat conduction plate 221 can better withstand the vibration, jolt, and impact generated during vehicle driving through its own strength.

[0057] For example, in an embodiment, the cold storage shell 222 is made of metal, and the heat conduction plate 221 is connected to the cold storage shell 222 by screwing, clamping, or gluing.

[0058] For example, the heat conduction plate 221 can be fixedly arranged on the edge of the cold storage shell 222 at the mounting port 222a by bolts, screws, or the like to cover the mounting port 222a. The heat conduction plate 221 can also be arranged on the edge of the cold storage shell 222 at the mounting port 222a by a clasp and a slot connection method, for example, one of the heat conduction plate 221 and the cold storage shell 222 is provided with a clasp, and the other of the heat conduction plate 221 and the cold storage shell 222 is provided with a slot, and the clasp and the slot are clamped and matched. The heat conduction plate 221 can also be fixedly arranged on the edge of the cold storage shell 222 at the mounting port 222a by an adhesive method.

[0059] Here, the heat conduction plate 221 is connected to the cold storage shell 222 by screwing, clamping, or gluing, which not only improves the connection strength between the two and facilitates heat conduction, but also makes the cold storage shell 222 and the heat conduction plate 221 separable for manufacturing, which is convenient for maintenance and replacement.

[0060] In an embodiment, the heat conduction plate 221 is integrally formed with the cold storage shell 222. For example, the cold storage shell 222 can be made of plastic or nylon material, and the heat conduction plate 221 can be integrally formed with the cold storage shell 222 by injection molding. In this way, the sealing and reliability between the heat conduction plate 221 and the cold storage shell 222 are enhanced, and the heat exchange performance is better.

[0061] In another aspect, the present application provides a thermal management system, which includes the vehicle-mounted refrigerator 100 in any of the above embodiments.

[0062] The thermal management system provided by the present application has the advantages of the vehicle-mounted refrigerator 100 described above, and has the advantage of good heat exchange effect.

[0063] For example, in an embodiment, the thermal management system can include a compressor, a condenser, a refrigeration circuit, an air conditioner evaporator, and an air conditioner expansion valve. The compressor, the condenser, the air conditioner evaporator, and the air conditioner expansion valve can be arranged on the refrigeration circuit. The compressor can compress the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant and flow to the condenser through the refrigeration circuit. In the condenser, the high-temperature and high-pressure gaseous refrigerant is condensed and liquefied into high-temperature and high-pressure liquid refrigerant, and then flows to the air conditioner expansion valve. The air conditioner expansion valve can throttle the liquid refrigerant into low-temperature and low-pressure gaseous-liquid mixed state refrigerant, and finally flows to the air conditioner evaporator. The air conditioner evaporator can vaporize the low-temperature and low-pressure mixed state refrigerant into low-temperature and low-pressure gaseous refrigerant by absorbing the temperature in the vehicle, thereby achieving refrigeration in the vehicle. The low-temperature and low-pressure gaseous refrigerant can flow back to the compressor through the refrigeration circuit, and the cycle is repeated.

[0064] In an embodiment, the cold storage assembly 22 has a refrigerant pipe 22a, and the refrigerant pipe 22a is in communication with the refrigeration circuit of the thermal management system.

[0065] For example, the refrigerant pipe 22a can include a refrigerant outlet pipe and a refrigerant inlet pipe. The cold storage shell 222 can be formed with a refrigerant pipe opening 222b, and the mounting opening 222a and the refrigerant pipe opening 222b can be located at opposite ends of the cold storage shell 222 along the first direction. One end of the refrigerant inlet pipe and one end of the refrigerant outlet pipe can pass through the refrigerant pipe opening 222b and be in communication with the refrigeration circuit of the vehicle, and the other end of the refrigerant inlet pipe and the other end of the refrigerant outlet pipe can be in communication with the inlet and outlet of the evaporator 223, respectively, so that the low-temperature and low-pressure gaseous-liquid mixed state refrigerant in the refrigeration circuit of the vehicle can enter the evaporator 223 through the refrigerant inlet pipe, the evaporator 223 can absorb the temperature in the cold storage shell 222 to vaporize the mixed state refrigerant into low-temperature and low-pressure gaseous refrigerant, thereby achieving refrigeration, and the gaseous refrigerant can flow back to the refrigeration circuit of the thermal management system through the refrigerant outlet pipe, and finally flow back to the compressor of the vehicle, and the cycle is repeated.

[0066] Here, by connecting the refrigerant pipe 22a of the cold storage assembly 22 with the refrigeration circuit of the thermal management system, the refrigerant can enter the cold storage assembly 22 through the refrigerant pipe 22a for refrigeration, cold storage and cold release, that is, the vehicle-mounted refrigerator 100 provided by the present application utilizes the refrigerant of the refrigeration circuit of the vehicle, so that it is not necessary to set an independent compressor, thus the occupied space of the heat exchange module and the manufacturing cost can be reduced.

[0067] In an embodiment, the air cooling assembly 21 comprises a semiconductor refrigeration sheet, which is arranged between the fin 212 and the heat conduction plate 221.

[0068] Here, by arranging the semiconductor refrigeration sheet and the fin 212 on the heat conduction plate 221, the cold energy generated by the evaporator 223 can be conducted to the semiconductor refrigeration sheet through the heat conduction plate 221, and then heat exchanged with the air flow to be heated in the placing cavity 11a through the fin 212, so as to increase the heat exchange area with the air flow to be heated, and based on the characteristics of the semiconductor refrigeration sheet, the semiconductor refrigeration sheet can obtain a lower temperature than the evaporator 223, thereby improving the heat exchange rate and heat exchange effect.

[0069] For example, in an embodiment, the fin 212 can be fixedly arranged on the heat conduction plate 221 by screwing, so as to clamp the semiconductor refrigeration sheet and reduce the falling probability.

[0070] In an embodiment, a heat conduction coating is coated between the heat conduction plate 221 and the semiconductor refrigeration sheet and / or between the fin 212 and the semiconductor refrigeration sheet.

[0071] For example, the heat conduction coating can be silicone grease. In this way, the heat conduction can be further strengthened, and the heat exchange performance can be improved.

[0072] For example, in an embodiment, referring to Figure 1 , the vehicle-mounted refrigerator 100 comprises a first heat preservation shell (not shown in the figure) and a second heat preservation shell 3, the first heat preservation shell is formed with an assembly opening communicating with the internal space thereof, the outer shell 11 is arranged in the first heat preservation shell, the second heat preservation shell 3 comprises a heat preservation inner shell 31 and a heat preservation outer shell 32, the heat exchange device 2 can be arranged in the heat preservation inner shell 31, the heat preservation inner shell 31 can be arranged in the heat preservation outer shell 32, and the heat preservation outer shell 32 covers the assembly opening.

[0073] Here, by arranging the first heat preservation shell and the second heat preservation shell 3, on the one hand, the outer shell 11 and the heat exchange device 2 can be protected to a certain extent, so as to reduce the damage caused by physical collision, scratching and the like of the outside world during installation or transportation, and improve the service life thereof; on the other hand, the first heat preservation shell and the second heat preservation shell 3 can reduce the heat exchange between the heat exchange device 2 and the outer shell 11 and the outside world, and reduce the temperature fluctuation.

[0074] In still another aspect, the embodiment of the present application provides a vehicle comprising the heat management system in the above embodiments.

[0075] The vehicle provided by the embodiment of the present application has the advantages of the above vehicle-mounted refrigerator 100, and has the characteristics of good refrigeration effect and comfort.
