DETAILED DESCRIPTION

[0030] It should be noted that the embodiments and technical features in the present application can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as the explanation and description of the purpose of the present application, and should not be regarded as improper limitation on the present application.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The "first", "second" and the like in the embodiments of the present application are only for the purpose of description, and should not be understood as indicating or implying relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0032] The present application provides a refrigerator on vehicle 100 in one aspect, please refer to Figures 1 to 4The vehicle-mounted refrigerator 100 comprises a storage module 1 and a heat exchange module 2. The storage module 1 comprises an outer shell 11 and a storage shell 12. The outer shell 11 is formed with a placing cavity 11a and a through hole 11b communicating with the placing cavity 11a. The storage shell 12 is arranged in the placing cavity 11a. The heat exchange module 2 is detachably arranged outside the outer shell 11 to cover the through hole 11b. The heat exchange module 2 is used for heat exchange with the storage shell 12. The vehicle-mounted refrigerator 100 provided by the application can realize the refrigeration effect by arranging the storage shell 12 in the placing cavity 11a and arranging the heat exchange module 2 outside the outer shell to cover the through hole 11b. The heat exchange module 2 can transfer cold energy into the placing cavity 11a through the through hole 11b to exchange heat with the storage shell 12. The outer shell 11 can protect the storage shell 12 to some extent and reduce heat loss, thereby improving the heat preservation effect.

[0033] Through the detachable connection mode of the heat exchange module 2 and the storage module 1, on the one hand, when the vehicle-mounted refrigerator 100 needs to be maintained and repaired, the heat exchange module 2 can be detached from the through hole 11b, and then the heat exchange module 2 and / or the storage module 1 can be checked and maintained separately, which is convenient and efficient. On the other hand, when the storage module 1 or the heat exchange module 2 needs to be upgraded, such as increasing the space of the storage shell 12 or improving the refrigeration capacity of the heat exchange module 2, the part that needs to be replaced can be detached, and then the upgraded part can be installed, without the need to replace the entire vehicle-mounted refrigerator 100, thereby forming a modular installation and being good in flexibility.

[0034] For example, in an embodiment, the first direction can be a front-rear direction; the second direction can be one of an up-down direction and a left-right direction, such as the up-down direction; and the third direction can be the other of the up-down direction and the left-right direction, such as the left-right direction.

[0035] It should be noted that up can mean the direction of the top of the vehicle, and down is opposite to up. The first direction, the second direction and the third direction can be perpendicular to each other to form a three-dimensional perpendicular coordinate system.

[0036] For example, in an embodiment, Figure 2 R1 in the above can be the first direction, R2 can be the second direction, and R3 can be the third direction.

[0037] In an embodiment, please refer to Figure 1 and Figure 2 The outer shell 11 comprises a first heat preservation shell 111 and an air cooling shell 112. The first heat preservation shell 111 is formed with a placing cavity 11a and a mounting hole 111a communicating with the placing cavity 11a. The air cooling shell 112 is detachably arranged in the mounting hole 111a. The air cooling shell 112 is formed with an air duct 112a, an air inlet and a through hole 11b communicating with the air duct 112a. A fan 13 is arranged in the air duct 112a. The fan 13 is used to drive airflow to flow between the placing cavity 11a and the air duct 112a.

[0038] Exemplarily, the end face of the air-cooled shell 112 with the through port 11b can be detachably connected with the heat exchange module 2, and the end face of the air-cooled shell 112 relative to the through port 11b can be detachably connected with the end face of the first heat preservation shell 111 with the mounting port 111a. The air port can include an air inlet 112b and an air outlet 112c, both of which are communicated with the air duct 112a and the mounting port 111a. The air fan 13 can be arranged at the air outlet 112c to drive the air flow to be heat exchanged to pass through the placement cavity 11a, enter the air duct 112a through the air inlet 112b, and then enter the placement cavity 11a through the air outlet 112c to be heat exchanged with the storage shell 12.

[0039] Here, by detachably connecting the air-cooled shell 112 with the first heat preservation shell 111, the air fan 13, the air duct 112a or the air port in the air-cooled shell 112 can be conveniently and quickly overhauled and adjusted. On the one hand, by arranging the first heat preservation shell 111, the storage shell 12 can be protected to some extent, and damage such as physical collision or scratching from the outside during installation or transportation is reduced, and the service life is improved. On the other hand, the first heat preservation shell 111 can reduce heat exchange between the storage shell 12 and the outside, and reduce large temperature fluctuations.

[0040] Exemplarily, in an embodiment, the air fan 13 can be an axial flow fan 13. In this way, the high-flow output of the air flow can be improved to accelerate forced convection heat exchange and fast refrigeration rate.

[0041] In an embodiment, referring to Figure 1 , the first heat preservation shell 111 includes an inner container 1111 and an outer container 1112. The inner container 1111 forms the placement cavity 11a and the mounting port 111a, and is arranged in the outer container 1112. A heat insulation material 1113 is arranged between the inner container 1111 and the outer container 1112.

[0042] Exemplarily, the heat insulation material 1113 can be foamed material or VIP plate (vacuum insulation panel).

[0043] Here, by arranging the heat insulation material 1113 between the inner container 1111 and the outer container 1112, the heat insulation effect can be further improved, and the heat exchange between the storage shell 12 and the outside can be reduced.

[0044] In an embodiment, referring to Figures 1 to 3 , the edge of the mounting port 111a forms a first clamping part 111b, and the outer periphery of the air-cooled shell 112 forms a second clamping part 112d matched with the first clamping part 111b.

[0045] Exemplarily, the inner container 1111 is located at the edge of the mounting port 111a and forms the first clamping part 111b.

[0046] Here, through the clamping cooperation mode of the first clamping part 111b and the second clamping part 112d, the use of fasteners such as screws or bolts can be reduced to reduce manufacturing costs and be economical.

[0047] In an embodiment, referring to Figures 1 to 3 , one of the first clamping part 111b and the second clamping part 112d is a buckle, and the other is a clamping groove.

[0048] For example, the first clamping part 111b can be a clamping groove, and the second clamping part 112d can be a buckle.

[0049] Here, through the clamping cooperation of the buckle and the clamping groove, connection can be performed without additional auxiliary tools, and the installation and disassembly efficiency and the connection strength are high.

[0050] For example, in an embodiment, the shape of the mounting port 111a is not limited, for example, the projection shape of the mounting port 111a along the first direction can be a rounded rectangle.

[0051] In an embodiment, referring to Figures 1 to 4 , the number of the first clamping part 111b and the second clamping part 112d is multiple, the multiple first clamping parts 111b are circumferentially spaced apart at the edge of the mounting port 111a, and the multiple second clamping parts 112d are correspondingly arranged on the outer periphery of the air-cooled shell 112. Each first clamping part 111b is clamped and cooperated with the corresponding second clamping part 112d.

[0052] For example, the two side edges of the mounting port 111a along the second direction and the two side edges along the third direction can each be formed with three first clamping parts 111b, and the two side edges of the air-cooled shell 112 along the second direction and the two side edges along the third direction can each be formed with three second clamping parts 112d. Each first clamping part 111b is clamped and cooperated with the corresponding first clamping part 111b.

[0053] In this way, by arranging multiple first clamping parts 111b and second clamping parts 112d circumferentially, the connection strength between the air-cooled shell 112 and the first heat preservation shell 111 can be further improved, and the situation that the two shells fall off can be reduced, and the working stability is good.

[0054] In an embodiment, referring to Figure 2 and Figure 3A plug-in portion 111c is formed on one of the outer periphery of the air-cooled housing 112 and the edge of the mounting port 111a. A slot 112e1 is formed on the other of the outer periphery of the air-cooled housing 112 and the edge of the mounting port 111a. The slot 112e1 has an insertion port 112e2 facing the plug-in portion 111c. The plug-in portion 111c enters or exits the slot 112e1 through the insertion port 112e2. When the plug-in portion 111c is located in the slot 112e1, the outer surface of the plug-in portion 111c abuts against the groove wall of the slot 112e1.

[0055] For example, the inner liner 1111 has a plug-in portion 111c formed at the edge of the mounting port 111a. The plug-in portion 111c can be a part of the inner liner 1111, such as the wall surface of the inner liner 1111 located at the mounting port 111a. The outer peripheral surface of the air-cooled shell 112 can be formed with a plug-in block 112e. The plug-in block 112e has a slot 112e1 and a plug-in port 112e2 along a first direction toward the side near the plug-in portion 111c. The plug-in block 112e is disposed through both ends along a third direction to form a clearance port 112e3. The clearance port 112e3 is used to avoid the plug-in block 112e located in the slot 112e1. The plug-in portion 111c can be inserted into or removed from the slot 112e1 through the plug-in port 112e2.

[0056] In this way, the connection stability between the air-cooled shell 112 and the first insulation shell 111 can be further improved by the cooperation between the plug part 111c and the slot 112e1, and the shaking situation can be reduced.

[0057] As an example, in one embodiment, please refer to Figures 2 to 4 There are multiple plug-in parts 111c and slots 112e1. Multiple plug-in parts 111c can be arranged at intervals along the circumference at the edge of the mounting port 111a. The plug-in parts 111c and the first snap-fit ​​part 111b are arranged alternately. Multiple slots 112e1 are correspondingly arranged on the outer peripheral surface of the air-cooled shell 112 to further improve the connection stability between the air-cooled shell 112 and the first insulation shell 111.

[0058] In one embodiment, please refer to Figure 1 The heat exchange module 2 includes a metal plate 21, an evaporator 22, a phase change material, and a cold storage shell 23. The cold storage shell 23 has a communication port 23a that communicates with its internal space. The phase change material is filled inside the cold storage shell 23. The evaporator 22 is disposed inside the cold storage shell 23. One end face of the metal plate 21 is covered by the communication port 23a, and the other end face of the metal plate 21 is detachably disposed in the through port 11b. The evaporator 22 is used to generate cooling capacity.

[0059] For example, the phase change material can be water. The metal plate 21 is detachably connected to the air-cooled housing 112.

[0060] In this way, by arranging the evaporator 22, the phase change material, the cold storage shell 23 and the metal plate 21, the evaporator 22 can perform refrigeration, the cold storage shell 23 can insulate the inside to a certain extent to reduce the loss of cold, and the phase change material in the cold storage shell 23 can store a certain amount of cold for subsequent cold release. The released cold can be transferred to the placement cavity 11a through the metal plate 21 for heat exchange. Here, the cold transfer through the metal plate 21 can further improve the refrigeration rate and refrigeration effect, and the metal plate 21 also has a certain strength and can better withstand the vibration, bumping and impact generated during vehicle driving.

[0061] For example, in an embodiment, the material of the cold storage shell 23 is metal, and the metal plate 21 is connected to the cold storage shell 23 by screwing and a sealing gasket, or the metal plate 21 is connected to the cold storage shell 23 by welding.

[0062] For example, the metal plate 21 can be fixed on the edge of the cold storage shell 23 at the communication port 23a by bolts, screws or the like to cover the communication port 23a. The metal plate 21 and the edge of the communication port 23a can be provided with a sealing gasket.

[0063] Here, the metal plate 21 is connected to the cold storage shell 23 by screwing or welding, which can not only improve the connection strength between the two and facilitate heat conduction, but also make the cold storage shell 23 and the metal plate 21 can be manufactured separately, which is convenient for maintenance and replacement.

[0064] In an embodiment, the metal plate 21 and the cold storage shell 23 are integrally formed.

[0065] For example, the material of the cold storage shell 23 can be plastic or nylon material, and then the metal plate 21 is integrally formed with the cold storage shell 23 by injection molding. In this way, the sealing and reliability between the metal plate 21 and the cold storage shell 23 are enhanced, and the heat exchange performance is better.

[0066] Another aspect of the embodiment of the application provides a heat management system, which comprises the vehicle-mounted refrigerator 100 in any one of the above embodiments.

[0067] The heat management system provided by the application has the advantages of the vehicle-mounted refrigerator 100, and is convenient to maintain and repair.

[0068] Exemplarily, in an embodiment, the heat management system can include a compressor, a condenser, a refrigeration circuit, an air conditioning evaporator and an air conditioning expansion valve. The compressor, the condenser, the air conditioning evaporator and the air conditioning expansion valve can be all arranged on the refrigeration circuit. The compressor can compress the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant and flow through the refrigeration circuit to the condenser, where 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 conditioning expansion valve, which can throttle the liquid refrigerant into low-temperature and low-pressure gaseous-liquid mixed-state refrigerant, and finally flows to the air conditioning evaporator, which can vaporize the low-temperature and low-pressure mixed-state refrigerant into low-temperature and low-pressure gaseous refrigerant by absorbing the temperature inside the vehicle, thereby achieving refrigeration in the vehicle, and the low-temperature and low-pressure gaseous refrigerant can flow back to the compressor along the refrigeration circuit for compression, and the cycle is repeated.

[0069] In an embodiment, the refrigerant pipe 22a of the evaporator 22 is in communication with the refrigeration circuit of the heat management system.

[0070] Exemplarily, the refrigerant pipe 22a can include a refrigerant outlet pipe and a refrigerant inlet pipe. The cold storage shell 23 can be formed with a refrigerant pipe opening 23b, and the communication opening 23a and the refrigerant pipe opening 23b can be located at opposite ends of the cold storage shell 23 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 23b to communicate 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 respectively communicate with the inlet and outlet of the evaporator 22, so that the low-temperature and low-pressure gaseous-liquid mixed-state refrigerant in the refrigeration circuit of the vehicle can enter the evaporator 22 through the refrigerant inlet pipe, the evaporator 22 can absorb the temperature inside the cold storage shell 23 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 heat management system through the refrigerant outlet pipe, and finally flow back to the compressor of the vehicle, and the cycle is repeated.

[0071] Here, by communicating the refrigerant pipe 22a of the evaporator 22 with the refrigeration circuit of the heat management system, the refrigerant can enter the evaporator 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 arrange an independent compressor, thus the occupied space of the heat exchange module 2 and the manufacturing cost can be reduced.

[0072] In an embodiment, please refer to Figure 1 The heat exchange module 2 includes fins 24 and semiconductor refrigeration pieces, the fins 24 are arranged on the end face of the metal plate 21 covering the through opening 11b, and the semiconductor refrigeration pieces are arranged between the fins 24 and the metal plate 21.

[0073] Exemplarily, in the state that the metal plate 21 covers the through opening 11b, the fins 24 and the semiconductor refrigeration pieces can be located in the air duct 112a.

[0074] Here, by setting the semiconductor refrigeration sheet and the fin 24 on the metal plate 21 covering the end face of the through hole 11b, the cold produced by the evaporator 22 can be conducted to the semiconductor refrigeration sheet through the metal plate 21, and then heat-exchanged with the air flow to be heated placed in the cavity 11a through the heat dissipation fin 24, thereby increasing 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 22, thereby improving the heat exchange rate and heat exchange effect.

[0075] For example, in an embodiment, the fin 24 can be fixedly arranged on the metal plate 21 by screwing to clamp the semiconductor refrigeration sheet and reduce the possibility of falling off.

[0076] In an embodiment, a heat-conducting coating is coated between the metal plate 21 and the semiconductor refrigeration sheet and / or between the fin 24 and the semiconductor refrigeration sheet.

[0077] For example, the heat-conducting coating can be silicone grease. In this way, the heat transfer can be further strengthened, and the heat exchange performance can be improved.

[0078] In an embodiment, referring to Figure 1 , the vehicle-mounted refrigerator 100 comprises a second heat-insulating shell 3, which covers the outside of the heat exchange module 2 and is detachably connected with the outer shell 11.

[0079] For example, the second heat-insulating shell 3 comprises an inner shell 31 and a protective shell 32, the heat exchange module 2 can be arranged in the inner shell 31, the inner shell 31 can be arranged in the protective shell 32, and a heat-insulating material 1113 can be filled between the inner shell 31 and the protective shell 32. The protective shell 32 can be detachably connected with the first heat-insulating shell 111.

[0080] Here, by setting the second heat-insulating shell 3, on the one hand, the heat exchange module 2 can be protected to some extent, reducing the damage caused by physical impact, scratching, etc. from the outside during installation or transportation, thereby improving its service life; on the other hand, the second heat-insulating shell 3 can reduce heat exchange between the heat exchange module 2 and the outside, thereby reducing the temperature fluctuation. By detachably connecting the second heat-insulating shell 3 with the outer shell 11, the maintenance and repair are facilitated, and the structure is compact.

[0081] In an embodiment, referring to Figure 1 , the outside of the second heat-insulating shell 3 is formed with a third mounting hole 32a, the outside of the outer shell 11 is formed with a fourth mounting hole 1112a, and the vehicle-mounted refrigerator 100 comprises a second fastener 5, which is arranged through the third mounting hole 32a and the fourth mounting hole 1112a.

[0082] Exemplarily, the two sides of the protective shell 32 along the second direction and the two sides along the third direction can each form a mounting lug, which is formed with a third mounting hole 32a, which can be a light hole; the two sides of the outer shell 1112 along the second direction and the two sides along the third direction can each form a mounting lug, which is formed with a fourth mounting hole 1112a, which can be a threaded hole. The second fastener 5 can be a screw or a bolt, etc., which can be screwed through the third mounting hole 32a and the fourth mounting hole 1112a.

[0083] Here, the second heat preservation shell 3 and the outer shell 11 are connected by the second fastener 5, which not only facilitates installation and removal, but also improves the connection strength between the second heat preservation shell 3 and the outer shell 11, and has good working stability.

[0097] It should be noted that the bearing portion 21c can be an abutting end surface, and the limiting block 11f is formed by the edge of the through hole 11b, and the metal plate 21 forms the bearing portion 21c, for example, the bearing portion 21c can be the end surface of the metal plate 21 along the third direction, that is, the limiting block 11f abuts against the two end surfaces of the metal plate 21 along the third direction.

[0098] For example, in an embodiment, referring to Figure 4 The through hole 11b is provided with sealing foam 6, and when the heat exchange module 2 is connected at the through hole 11b, the gap between the through hole 11b and the heat exchange module 2 can be sealed by extruding the sealing foam 6, so as to reduce the cold leakage.
