[0026] The delivery box 100 of the embodiment of the present application can be used for takeout or other fields, and can be used to place meals, etc.

[0027] See also Figures 1 to 3The delivery box 100 includes: a box body 1 and a refrigeration device 2. The refrigeration device includes a condenser 21, a compressor 22 and an evaporator 23. The evaporator 23 is located in the space enclosed by the box body 1, and the condenser 21 and the compressor 22 are located outside the space enclosed by the box body 1, which saves the active cooling fan, reduces the failure risk of the refrigeration device 2, improves the operational reliability, and does not need to consider the waterproof and foreign body prevention issues of the cooling fan; at the same time, it reduces the space occupied in the box body 1 and improves the volume utilization rate of the box body 1; furthermore, the box body 1 does not need to have ventilation holes, which improves the waterproof performance and foreign body prevention capabilities.

[0028] The compressor 22 is used to compress the steam with a lower pressure into the steam with a higher pressure, so that the volume of the steam is reduced and the pressure is increased. The evaporator 23 absorbs the heat in the box 1 to reduce the temperature in the box 1.

[0029] The compressor 22 inhales the relatively low-pressure working fluid vapor coming out of the evaporator 23, increases its pressure, and then sends it to the condenser 21, where it is condensed into a relatively high-pressure liquid. After being throttled by a throttle valve, it becomes a relatively low-pressure liquid and is then sent to the evaporator 23, where it absorbs heat and evaporates to become relatively low-pressure vapor, which is then sent to the inlet of the compressor 22, thereby completing a refrigeration cycle.

[0030] The compressor 22 is the power of the refrigeration cycle. It is driven by an electric motor and rotates continuously. In addition to timely extracting the steam in the evaporator 23 to maintain low temperature and low pressure, it also increases the pressure and temperature of the refrigerant steam through compression, creating conditions for transferring the heat of the refrigerant steam to the external environment medium. That is, the low-temperature and low-pressure refrigerant steam is compressed to a high-temperature and high-pressure state so that the refrigerant steam can be condensed using air or water at room temperature as a cooling medium.

[0031] Optionally, the condenser 21 may be a pipeline connected to the compressor 22 .

[0032] The housing 1 includes a bottom wall 11 and a plurality of side walls 12 connected to the bottom wall 11 , and the condenser 21 and the compressor 22 are fixed on one of the side walls 12 .

[0033] See also Figure 4 When the delivery box 100 is placed on the rear seat 201 of the vehicle 200 , the bottom wall 11 is pressed against the rear seat 201 , and the plurality of side walls 12 face the front, rear, left, and right of the vehicle 200 , respectively.

[0034] When the delivery box 100 is placed on the rear seat 201 of the vehicle 200, the plurality of side walls 12 include a first side wall 121 facing the rider, and the condenser 21 and the compressor 22 are fixed on the first side wall 121 and located on the windward side, so as to achieve better heat dissipation effect.

[0035] The refrigeration device 2 includes a heat sink 24 , and the heat sink 24 contacts the condenser 21 to transfer heat, so as to improve the heat dissipation effect.

[0036] Optionally, the heat sink 24 may be integrally provided with the condenser 21 or may be separately provided.

[0037] See also Figure 1 and Figure 5 The heat sink 24 includes a first heat sink 241, a second heat sink 242 and a third heat sink 243. The side walls 12 include a second side wall 122 and a third side wall 123 connected to the first side wall 121. The first heat sink 241 covers at least a portion of the first side wall 121, the second heat sink 242 covers at least a portion of the second side wall 122, and the third heat sink 243 covers at least a portion of the third side wall 123.

[0038] The heat sink 24 covers the windward surface and transitions to the side of the box body 1, thereby improving the heat dissipation effect; at the same time, it does not affect the main information display surfaces of the delivery box 100, namely the back, left, right, and top.

[0039] The first heat dissipation portion 241 includes a split first base portion 2411 and a second base portion 2412. The second heat dissipation portion 242 is bent and extended from the first base portion 2411, and the third heat dissipation portion 243 is bent and extended from the second base portion 2412. The heat dissipation element 24 is divided into two parts, and the heat dissipation element 24 is easy to process and shape, and is also convenient to be assembled and fixed with the box body 1.

[0040] The first base 2411 includes a first connection portion 24112 and a pair of first side walls 24113 extending from opposite ends of the first connection portion 24112. The first connection portion 24112 and the pair of first side walls 24113 enclose a first space, and at least a portion of the compressor 22 is located in the first space.

[0041] The second base 2412 includes a second connecting portion 24122 and a pair of second side walls 24123 extending from opposite ends of the second connecting portion 24122 . The second connecting portion 24122 and the pair of second side walls 24123 enclose a second space 24124 . At least a portion of the compressor 22 is located in the second space 24124 .

[0042] The heat sink 24 includes a plurality of first heat sink fins 244 and a plurality of second heat sink fins 245. The first heat sink fins 244 are disposed on the first base 2411 and the second heat sink 242, and the second heat sink fins 245 are disposed on the second base 2412 and the third heat sink 243. The arrangement of the first heat sink fins 244 and the second heat sink fins 245 ensures an effective heat sink area and improves the heat sink effect; at the same time, it can prevent the rider from contacting the high-temperature condenser 21, thereby improving the safety of the system.

[0043] The free end of the first heat dissipation fin 244 arranged on the first base 2411 is inclined toward the first end 1211 of the first side wall 121, and / or the free end of the second heat dissipation fin 245 arranged on the second base 2412 is inclined toward the second end 1212 opposite to the first end 1211.

[0044] When the delivery box 100 is in use, the compressor 22 transfers heat to the condenser 21, and the condenser 21 transfers heat to the heat sink 24. The heat is transferred from high temperature to low temperature in the form of heat conduction, and is finally dissipated into the atmosphere through the air flowing near the first heat sink fins 244 and the second heat sink fins 245.

[0045] The heat dissipation area of ​​the refrigeration device 2 is simulated and fitted by the whole machine to ensure that the heat dissipation requirements of low-power refrigeration can be met in a breeze environment without extremely high temperatures.

[0046] The high temperature area of ​​the refrigeration device 2 is in the middle of the box body 1 , and the outer edge of the first heat dissipation fin 244 and the outer edge of the second heat dissipation fin 245 are at a lower temperature, which can prevent the rider from touching the high temperature parts and causing discomfort.

[0047] See also Figures 2 to 3 The delivery box 100 includes an electronic module 3, which is located outside the space enclosed by the box body 1 and is fixed to the compressor 22 and / or the first side wall 121 to reduce the space occupied in the box body 1 and improve the volume utilization of the box body 1.

[0048] The electronic module 3 comprises a compressor driver 31 and / or a networking module 32 and / or a controller 33 and / or a power plug terminal 34 and / or an adapter 35 .

[0049] The setting of the networking module 32 enables the delivery box 100 to be wirelessly connected to the rider's mobile phone, and the start and stop of the refrigeration device 2 can be controlled by the mobile phone, which is more convenient to use.

[0050] Optionally, the refrigeration device 2 may be started and shut down by a switch.

[0051] Optionally, the delivery box 100 includes a temperature detection device for detecting the amount of refrigerant supercooling.

[0052] Optionally, if the amount of supercooling is lower than a certain threshold, the power of the refrigeration device 2 is reduced, for example, the rotation speed of the compressor 22 is reduced.

[0053] The power plug terminal 34 can be connected to a vehicle so that the battery of the vehicle can supply power or charge the delivery box 100 to extend the refrigeration time of the delivery box 100 .

[0054] Optionally, the opening of the power plug terminal 34 faces downward to avoid accidental touching and improve waterproof performance.

[0055] Optionally, the compressor 22 is detachable. When refrigeration is not needed, the compressor 22 is detached to reduce the weight of the delivery box 100 .

[0056] Optionally, the connectors of the compressor 22, the condenser 21 and the electronic module 3 are arranged in the center for easy installation and disassembly; at the same time, the compressor 22, the condenser 21 and the electronic module 3 can also be protected, thereby improving the overall anti-fall performance of the delivery box 100.
