Description

Technical Field

[0001] This utility model relates to the field of refrigeration, and in particular to a refrigerated transport box and a refrigerated transport vehicle. Background Technology

[0002] In logistics and transportation, fruits, vegetables, or chilled foods often require low-temperature storage. Therefore, some logistics transport containers are equipped with refrigeration units to keep the interior of the container cool.

[0003] In related technologies, some logistics transport boxes with refrigeration devices use photovoltaic modules for power. To ensure continued cooling inside the transport box even after the photovoltaic modules stop supplying power, phase change energy storage materials are typically installed inside the box. However, in actual operation, due to weather conditions or geographical location, situations with short periods of sunshine are common. In such cases, the photovoltaic panels in the photovoltaic modules cannot absorb solar energy for an extended period to generate electricity, leading to insufficient power and compromising the continuous refrigeration of goods inside the transport box.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0023] Example 1:

[0024] A refrigerated transport box, as described in the following Figures 1-2 The device includes a first housing 1, a phase change cold storage component disposed within the first housing 1, a cooling component 3 for cooling the interior of the first housing, and a photovoltaic component 4 for supplying power to the cooling component 3. The photovoltaic component 4 is capable of converting solar energy into electrical energy. The photovoltaic component 4 is electrically connected to the cooling component 3. The photovoltaic component 4 includes a first photovoltaic panel 41 and at least one second photovoltaic panel 42. The first photovoltaic panel 41 is disposed on the top of the first housing 1, and the second photovoltaic panel 42 is disposed on at least one side of the top of the first housing 1.

[0025] In this embodiment, when the photovoltaic module 4 is working, the first photovoltaic panel 41 and the second photovoltaic panel 42 can simultaneously absorb solar energy, significantly increasing the solar energy receiving area of ​​the photovoltaic module 4 and improving its power generation efficiency. This, in turn, increases the operating time of the refrigerated transport box even when sunlight exposure is short. Furthermore, if one photovoltaic panel in the photovoltaic module 4 fails, the other photovoltaic panels can still continue to operate, improving the reliability of the photovoltaic module 4.

[0026] In this embodiment, at least one drive telescopic component 5 is provided on the first housing 1 for each second photovoltaic panel 42. The second photovoltaic panel 42 is rotatably connected to the first housing 1. This rotatable connection can be achieved through structures such as pins and hinges. The telescopic movement of the drive telescopic component 5 can cause the second photovoltaic panel 42 to rotate around the top side of the first housing 1, thereby adjusting the tilt angle of the second photovoltaic panel 42 relative to the top surface of the first housing 1. Therefore, when the second photovoltaic panel 42 is in power generation mode, the operator can adjust the tilt angle of the second photovoltaic panel 42 to maintain the optimal angle for receiving sunlight at different times or seasons, thus maintaining high power generation efficiency. Furthermore, when the second photovoltaic panel 42 is in a shutdown state, it can be controlled to rotate downwards, thereby reducing the horizontal space occupied by the second photovoltaic panel 42.

[0027] Specifically, the drive telescopic assembly 5 includes a telescopic component 51 and a fixed component 52. The telescopic component 51 can extend and retract relative to the fixed component 52. The telescopic component 51 is connected to the side of the second photovoltaic panel 42 near the first housing 1, and the fixed component 52 is connected to the outer side wall of the first housing 1. That is, the drive telescopic assembly 5 also serves to support the second photovoltaic panel 42. In addition, two drive telescopic assemblies 5 are provided for each second photovoltaic panel 42, and the two drive telescopic assemblies 5 are respectively connected to both ends of the second photovoltaic panel 42 to ensure the connection stability of the second photovoltaic panel 42.

[0028] In this embodiment, the drive telescopic component 5 is an electric telescopic rod, and the electric telescopic rod is electrically connected to the photovoltaic array, that is, the photovoltaic array 4 provides power to the electric telescopic rod.

[0029] In this embodiment, the photovoltaic module 4 further includes a photovoltaic controller and an energy storage module 43. The photovoltaic controller is electrically connected to the first photovoltaic panel 41 and the second photovoltaic panel 42, and the energy storage module 43 is electrically connected to the photovoltaic controller so that the photovoltaic controller can charge the energy storage module 43. The photovoltaic controller is used to charge the energy storage module 43 with the electrical energy converted by the first photovoltaic panel 41 and the second photovoltaic panel 42. The energy storage module 43 is also electrically connected to the cooling component 3 to supply power to the cooling component 3.

[0030] In this embodiment, the phase change energy storage component is a component containing phase change energy storage material. Phase change energy storage material refers to a substance that changes its physical state while maintaining a constant temperature and can provide latent heat. Therefore, on the one hand, the temperature inside the first chamber 1 can be dynamically adjusted by utilizing the phase change energy storage component's ability to absorb or release cold energy, resulting in more stable temperature control within the first chamber 1. On the other hand, the phase change energy storage component can absorb and store a certain amount of cold energy when the photovoltaic module 4 is generating sufficient power, and release it when the photovoltaic module 4 stops generating power for an extended period and the cooling component 3 cannot be activated, thereby extending the refrigeration time of the refrigerated transport box.

[0031] In this embodiment, the phase change cold storage assembly includes multiple cold storage plates 2 and a phase change material housed within the cold storage plates 2. The cold storage plates 2 are installed on the inner wall of the first housing 1. The phase change material may include at least one of organic composite phase change material or inorganic composite phase change material. Furthermore, the cold storage plates 2 are installed on the top wall inside the first housing 1. On the one hand, this reduces the space occupied by the cold storage plates 2 inside the first housing 1, which helps to increase the load capacity of the first housing 1. On the other hand, when the cold storage plates 2 are installed at the top inside the first housing 1, due to the higher density of cold air, it will sink to the bottom of the first housing 1, while hot air can rise and be absorbed by the cold storage plates 2, making the temperature distribution inside the first housing 1 more uniform.

[0032] In this embodiment, the refrigeration assembly 3 may include a compressor 32, an evaporator 31, a condenser, and an expansion valve connected to each other. Furthermore, the compressor 32, evaporator 31, condenser, and expansion valve form a refrigeration mechanism, and refrigeration of the first housing 1 can be achieved by placing the evaporator 31 inside the first housing 1. It should also be noted that the evaporator 31 only needs to be installed inside the first housing 1 to achieve refrigeration of the interior of the first housing 1. Specifically, the evaporator 31 can be spaced apart from the cold storage plate 2, or the refrigerant pipe of the evaporator 31 can be embedded within the cold storage plate 2.

[0033] In this embodiment, the refrigerated transport box also includes a second box body 6, which is fixed to the outer wall of the first box body 1. The compressor 32, condenser, and expansion valve in the refrigeration assembly 3 are all installed inside the second box body 6, which can prevent the heat emitted by the compressor 32 and condenser during operation from interfering with the temperature inside the first box body 1. At the same time, the photovoltaic controller and the energy storage module 43 are also installed inside the second box body 6.

[0034] The operation process of the refrigerated transport box in this embodiment is as follows:

[0035] During operation, the cooling component 3 and the photovoltaic component 4 work simultaneously. The photovoltaic component 4 supplies power to the cooling component 4, and the cooling component 3 cools the first box 1. Under normal circumstances, the temperature inside the first box will reach 0℃ within 2-4 hours. During this process, the cold storage component continuously absorbs the cold energy inside the box. When the cooling component stops working, the cold storage component continues to release cold energy, keeping the temperature inside the first box 1 at 0-8℃ for a long time. After a period of time, the cold energy of the cold storage component continues to be consumed until the temperature inside the first box 1 is greater than 8℃. Then the cooling component 3 starts working again, causing the temperature inside the first box 1 to drop to 0℃, so as to ensure the continuous operation of the first box 1 at low temperatures.

[0037] A refrigerated transport vehicle includes the refrigerated transport box as described in Example 1.
