[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0034] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0035] First, as Figure 1 and Figure 2 As shown, the present application provides a refrigeration device installed in a cabin, comprising:

[0036] A dry ice box 11, having an air inlet on one side and an air outlet on the other side, for storing dry ice;

[0037] Fan 12, disposed at the air inlet;

[0038] The air door 13 is arranged at the air outlet.

[0039] Specifically, when the refrigeration device 1 is used to cool the interior of the cabin 2, the fan 12 located at the air inlet supplies air to the interior of the dry ice box 11, and the air flows out of the dry ice box 11 through the damper 13 from the interior of the dry ice box 11. The airflow formed inside the dry ice box 11 accelerates the sublimation of the dry ice to absorb the heat inside the cabin 2, thereby cooling the interior of the cabin 2.

[0040] More specifically, compared to the passive refrigeration of ice blocks, the refrigeration device of the present application is provided with a fan 12 and a damper 13, which can ventilate the interior of the dry ice box 11, accelerate the sublimation process of dry ice so that the heat inside the cabin 2 can be absorbed more quickly, thereby shortening the refrigeration time. Secondly, ice blocks are heavy, while the refrigeration device of the present application uses dry ice stored in the dry ice box 11 for refrigeration, which is light in weight and convenient for loading and unloading in the cabin 2. In addition, the dry ice manufacturing time of the refrigeration device of the present application is shorter than the freezing time of ice blocks, and can prepare for the refrigeration process more quickly. In addition, the refrigeration device of the present application refrigerates the interior of the cabin through cold air circulation, and does not need to cover the entire interior of the cabin like ice blocks, and occupies relatively less space.

[0041] The present application provides a refrigeration device, which is provided with a fan 12 and a damper 13, which can ventilate the interior of the dry ice box 11 and accelerate the sublimation process of the dry ice so that the heat inside the cabin 2 can be absorbed more quickly, thereby shortening the refrigeration time and improving the refrigeration efficiency; and the refrigeration device of the present application is light in weight and easy to load and unload in the cabin 2; in addition, the dry ice manufacturing time of the refrigeration device of the present application is short, and the refrigeration device of the present application occupies a smaller internal space of the cabin 2.

[0042] Preferably, the dry ice box 11 is an upper-opening structure.

[0043] In some preferred embodiments, the fan 12 and the damper 13 are arranged opposite to each other.

[0044] In this embodiment, the fan 12 and the damper 13 of the refrigeration device of the present application are arranged opposite to each other, which is convenient for ventilation inside the dry ice box 11, and can make the air and the dry ice fully contact to facilitate cooling, thereby further shortening the refrigeration time.

[0045] like Figure 3 As shown, in some preferred embodiments, the refrigeration device further comprises:

[0046] The partition net 14 is disposed in the dry ice box 11 and is used to separate the storage positions of the dry ice in the dry ice box 11 . The partition net 14 has holes 141 .

[0047] In this embodiment, the refrigeration device of the present application is provided with a spacer net 14, whose holes 141 can ensure that air flows in the dry ice box 11, and the spacer net 14 can separate the dry ice when multiple pieces of dry ice are stored in the dry ice box 11, thereby increasing the contact area between the dry ice and the air to facilitate cooling, thereby further shortening the refrigeration time.

[0048] In some preferred embodiments, the spacer mesh 14 is wavy.

[0049] In this embodiment, the refrigeration device of the present application is provided with a wavy spacer mesh 14, which can reduce the contact area between the spacer mesh 14 and the dry ice, thereby increasing the contact area between the dry ice and the air, allowing the air and the dry ice to fully contact to facilitate cooling, thereby further shortening the refrigeration time.

[0050] In some preferred embodiments, the spacer net 14 is laid flat on the bottom of the dry ice box 11.

[0051] In this embodiment, the refrigeration device of the present application allows the spacer net 14 to be laid flat on the bottom of the dry ice box 11, and can make the air in the dry ice box 11 flow along the surface of the spacer net 14 based on the fan 12 and the damper 13 arranged on both sides of the dry ice box 11, so that the air can better contact with the dry ice for cooling.

[0052] like Figure 5 As shown, in some preferred embodiments, the refrigeration device further comprises:

[0053] The controller is electrically connected to the damper 13 and the fan 12, and is used to control the fan 12 and the damper 13 to be opened or closed at the same time.

[0054] Specifically, since the controller controls the fan 12 and the damper 13 to open and close at the same time, when the refrigeration device 1 is needed to be used for cooling, the fan 12 and the damper 13 are turned on to cooperate with each other to ventilate the inside of the dry ice box 11. When the refrigeration device 1 is not needed to be used for cooling, the fan 12 and the damper 13 are turned off at the same time to prevent the consumption of cold energy in the dry ice box 11 as much as possible.

[0055] In this embodiment, the refrigeration device of the present application is provided with a controller electrically connected to the damper 13 and the fan 12, which can ventilate the interior of the dry ice box 11 when the refrigeration device 1 is needed for refrigeration, and can prevent the consumption of cold energy in the dry ice box 11 as much as possible when the refrigeration device 1 is not needed for refrigeration.

[0056] In some preferred embodiments, the refrigeration device further comprises:

[0057] The temperature control module (not shown) is electrically connected to the fan 12 and is used to adjust the speed of the fan 12 according to the temperature of the air outlet.

[0058] Specifically, when the temperature at the air outlet is high, the temperature control module increases the speed of the fan 12, which can speed up the cooling speed of the refrigeration device 1, and when the temperature in the air outlet is low, the temperature control module slows down the speed of the fan 12, which can reduce the power consumption of the fan 12.

[0059] In this embodiment, the refrigeration device of the present application is provided with a temperature control and adjustment module, which can increase the refrigeration speed of the refrigeration device 1 or reduce the power consumption of the fan 12 .

[0060] Preferably, the temperature control and adjustment module includes:

[0061] A temperature sensor is arranged at the air outlet and is used to detect the temperature of the air outlet;
