Description

Technical Field

[0001] The present application relates to the field of cold chain transportation technology, and more specifically to an aviation temperature-controlled container. Background Art

[0002] In the current active temperature-controlled air boxes, the refrigeration machine is mostly embedded in one side of the box, and the power supply and control modules such as batteries and controllers are configured on one side of the refrigeration machine. The condenser of the refrigeration machine exchanges heat with the external environment through the air duct, and the evaporator is directly sent into the insulation space of the air box through the air duct to provide refrigeration for the goods in the insulation space.

[0003] The thermal insulation space of the air box generally stores vaccines, blood products or other goods that need to be refrigerated. The thermal insulation structure is a metal frame and a foam layer, so there will be no fire in the thermal insulation space. Electronic components, batteries and other devices are designed on the side of the refrigeration machine, which may cause fire.

[0004] The space on the refrigerator side of the aviation box is relatively closed, and only the inlet and outlet air ducts of the condenser are connected to the outside environment. When a fire occurs on the refrigerator side of the box, the traditional control solution is that the refrigerator is quickly shut down due to circuit failure, and the fire smoke particles can only move to the condenser air duct through diffusion, and finally to the external environment, that is, the aircraft cargo hold, and are monitored by the smoke sensor arranged in the cargo hold to trigger the alarm. The entire process of fire monitoring is relatively slow.

[0057] Now, refer to the attached Figure 1 To the attached Figure 4 Exemplary embodiments according to the present application are described in more detail.

[0058] refer to Figures 1 to 3The present application provides an aviation temperature-controlled container 100, which includes an insulation box 110, an equipment box 120 and a refrigeration system. The equipment box 120 is connected to the side of the insulation box 110 to form a storage space 128 between the insulation box 110 and the equipment box 120. The refrigeration system is arranged on the side of the insulation box 110 and is at least partially located in the storage space 128. The refrigeration system includes a refrigeration component, a main power supply device (not shown), a sensing device 180 and a backup power supply device 160. The refrigeration component is arranged on the side of the insulation box 110, and the refrigeration component includes a condenser 140 and a fan 150. The fan 150 is used to drive air to flow to the outside through the condenser 140 to dissipate heat to the outside environment. The main power supply device is located in the storage space 128, and the main power supply device is electrically connected to the refrigeration component to supply power to the refrigeration component when the refrigeration component is working. The sensing device 180 is arranged in the storage space 128, and the sensing device 180 is used to sense whether a fire occurs in the storage space 128. The backup power supply device 160 is located in the accommodating space 128 , and the backup power supply device 160 is electrically connected to the fan 150 , and is used to supply power to the fan 150 separately when the sensing device 180 senses a fire.

[0059] According to the aviation temperature-controlled container 100 of the present application, a backup power supply device 160 is separately configured for the fan 150 of the condenser 140. When a fire occurs, the backup power supply device 160 can be used to drive the fan 150 to work, quickly exhaust the smoke from the equipment box 120, and shorten the time for the fire protection system in the cabin to discover the fire.

[0060] The backup power supply device 160 may be configured as a backup battery pack. The main power supply device may be configured as a main battery pack or an external power supply interface. The sensing device 180 is preferably configured as a smoke sensor.

[0061] Preferably, the refrigeration system further includes a control device 170 , which is located in the accommodating space 128 , and the control device 170 is signal-connected to the sensing device 180 , the refrigeration assembly, the main power supply device, and the backup power supply device 160 .

[0062] refer to Figure 4 The control device 170 is configured to control the main power supply device to supply power to the refrigeration component and control the refrigeration component to operate normally when the sensing device 180 does not sense a fire.

[0063] When the sensing device 180 senses a fire, the control device 170 controls the main power supply device to stop supplying power to the refrigeration assembly, and controls the backup power supply device 160 to supply power to the fan 150, so that the fan 150 works. Thus, when a fire occurs, the refrigeration assembly is shut down as a whole to protect the equipment and prevent the fire from spreading further, while the fan 150 is turned on by the backup power supply device 160 to quickly spread the fire smoke in the equipment box 120 into the cabin, so that the fire fighting system in the cabin can detect the occurrence of the fire as soon as possible, thereby improving the response speed.

[0064] In addition, the control device 170 is further configured to control the backup power supply device 160 to stop supplying power to the fan 150 after supplying power for a predetermined time. The predetermined time can be set to 2 to 3 minutes. In this way, the fan 150 can be protected after the smoke is quickly diffused, and the possibility of the fire being further developed by the wind is reduced. At the same time, after the smoke diffuses into the cabin, the airflow generated by the fan 150 can be reduced to reduce the concentration of smoke in the cabin, further improving the response speed of the fire fighting system in the cabin.

[0065] As an optional embodiment, the control device 170 is also used to connect to the cabin fire protection system signal. The control device 170 is also configured to control the backup power supply device 160 to stop supplying power to the fan 150 when the cabin fire protection system is started.

[0066] The following will be combined Figure 1 , Figure 2 and Figure 3 The structure of the aviation temperature-controlled container 100 is described in more detail. The heat-insulating container body 110 has a door 111 ( Figure 2 As shown), the side where the door 111 is located is adjacent to the side where the equipment box 120 is set.

[0067] The equipment box 120 includes a top wall 121, a bottom wall 122, an outer wall 123 and a side wall 124. The top wall 121 and the bottom wall 122 are spaced apart and are respectively connected to the top and bottom ends of the heat preservation box 110. The outer wall 123 is connected between the outer ends of the top wall 121 and the bottom wall 122 and is spaced apart from the heat preservation box 110. The side wall 124 is located on the side of the equipment box 120 and is connected to the top wall 121, the bottom wall 122, the outer wall 123 and the heat preservation box 110, and an inspection door 127 is provided on the side wall 124. Among them, the top wall 121 extends in the horizontal direction, the outer wall 123 extends in the vertical direction, and the bottom wall 122 is inclined relative to the vertical direction. In other words, the bottom wall 122 forms an inclined surface.

[0068] The equipment box 120 is also provided with an inner warehouse body 130, and the inner warehouse body 130 can be connected to the heat preservation box body 110. The condenser 140, the fan 150, the backup power supply device 160 and the control device 170 are arranged in the inner warehouse body 130, and the sensing device 180 is arranged outside the inner warehouse body 130 to detect the environment in the accommodation space 128.

[0069] Specifically, refer to Figure 3 The inner compartment 130 includes a first compartment 131, a second compartment 134 and a third compartment 135 arranged side by side. The condenser 140 and the fan 150 are arranged in the first compartment 131, the backup power supply device 160 is arranged in the second compartment 134, and the control device 170 is arranged in the third compartment 135. The equipment box 120 is provided with an air inlet 125 and an air outlet 126. The air inlet 125 is arranged on the bottom wall 122 and communicates with the accommodation space 128. The air outlet 126 is arranged on the outer wall 123 and communicates with the outside. The first compartment 131 has an air inlet 132 and an air outlet 133, wherein the air inlet 132 is communicated with the accommodation space 128, and the air outlet 133 is connected to the air outlet 126.

[0070] Thus, when a fire occurs in the equipment box 120, the smoke in the storage space 128 is sensed by the sensing device 180, and the signal is transmitted to the control device 170. The control device 170 immediately cuts off the main power supply device to shut down the refrigeration component, and starts the backup power supply device 160 to operate the fan 150. Under the action of the fan 150, the outside air enters the storage space 128 through the air inlet 125, and brings the smoke into the fan 150, and is discharged to the outside cabin through the air outlet 126, so that the fire protection system in the cabin can detect the occurrence of the fire in the first time.

Unless adverse effects occur, various processing operations can be performed in a sequence different from the sequence of the above processes. The sequence of steps in the above processes can also be increased, merged or deleted according to actual needs.
