[0007] By adopting the above technical scheme, after the semiconductor refrigeration plate is energized, the temperature of the semiconductor cooling fins decreases and the temperature of the semiconductor heat dissipation fins increases. When the air flow inside the medical refrigerator passes through the cold end air duct, the semiconductor cooling fins cool the air flow, and the water vapor in the air flow condenses into liquid and is discharged from the inner shell along the condensate drain pipe; the air outside the inner shell enters the inner shell through the hot end air duct and continuously cools the semiconductor heat dissipation fins; the present application sets the dehumidification module outside the box body of the medical refrigerator, which reduces the occupancy of the storage space of the box body and improves the dehumidification effect.

[0009] By adopting the above technical scheme, since the semiconductor heat dissipation fins and the semiconductor cooling fins are integrally formed to form the semiconductor refrigeration plate, it is very necessary to set up a cross-area between the hot-end air duct and the cold-end air duct for installing the semiconductor refrigeration plate; moreover, setting up a cross-area between the hot-end air duct and the cold-end air duct can shorten the distance between the hot-end air duct and the cold-end air duct, reduce the volume of the inner shell, and reduce the manufacturing cost of the dehumidification device.

When the hot-end heat dissipation fan is running, the flow of gas inside the hot-end air duct can be accelerated, thereby enhancing the cooling effect on the semiconductor heat dissipation fins.

[0016] In the preferred technical solution of the dehumidification device of the above-mentioned medical refrigerator, the inner shell has a second filter screen, and the second filter screen is arranged at the air outlet of the hot end air duct.

[0017] By adopting the above technical solution, the second filter can block and filter the dust in the air entering the hot end air duct, thereby keeping the inside of the hot end air duct clean.

[0021] By adopting the above technical solution, the thermal insulation foam can effectively insulate the cold end air duct at low temperature, further improving the dehumidification effect of the dehumidification device.

[0050] As mentioned in the background technology, medical refrigerators are mainly used for the refrigeration, storage and transportation of medicines, reagents, vaccines, blood, etc. A built-in dehumidification module is provided inside the medical refrigerator. According to the characteristics of the refrigerated goods, the humidity inside the medical refrigerator needs to be adjusted accordingly through the built-in dehumidification module to ensure the quality of the refrigerated goods. However, the above-mentioned built-in dehumidification module occupies more storage space in the box liner, and the dehumidification effect is not obvious enough.

[0051] Therefore, in order to improve or solve the above technical problems, the embodiment of the present application provides a dehumidification device for a medical refrigerator. The technical solution provided in the embodiment of the present application includes:

[0052] The inner shell is arranged on the outside of the medical refrigerator. The inner shell is provided with a cold end air duct and a hot end air duct. Both ends of the cold end air duct are connected with the inside of the medical refrigerator. A condensate drain pipe is arranged at the lowest point of the cold end air duct, and both ends of the hot end air duct are arranged on the inner shell.

[0053] It also includes a semiconductor refrigeration sheet, which includes a semiconductor heat dissipation fin and a semiconductor cooling fin. The semiconductor heat dissipation fin is located inside the hot end air duct, and the semiconductor cooling fin is located inside the cold end air duct. A cold end circulation fan is arranged in the cold end air duct, and a hot end heat dissipation fan is arranged in the hot end air duct.

[0060] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a dehumidification device for a medical refrigerator, which includes: a dehumidification module shell 100, an inner shell 200, a mounting base 400 and a thermal insulation foam 700. The four corners of the dehumidification device are threaded with screws, and the screws fix the dehumidification device to the medical refrigerator. The dehumidification device is fixedly connected to the outside of the medical refrigerator, and the thermal insulation foam 700 fits tightly to the medical refrigerator.

[0061] Specifically, the present application arranges the dehumidification module outside the box body of the medical refrigerator, thereby reducing the storage space occupied by the inner liner of the box body.

[0062] Please refer to Figure 2 and Figure 3 In some embodiments provided in the present application, illustratively, the inner shell 200 is provided with a cold-end air duct 210 and a hot-end air duct 220, and the hot-end air duct 220 and the cold-end air duct 210 have an intersection area, and the two ends of the cold-end air duct 210 and the two ends of the hot-end air duct 220 respectively form an air inlet and an air outlet, and the cold-end air duct 210 and the hot-end air duct 220 are both groove-shaped, and the grooves are oriented in the same direction, and the lowest point of the cold-end air duct 210 is connected to a condensate drain pipe 211, and the two ends of the hot-end air duct 220 are both arranged on the inner shell 200 and are located on the adjacent sides of the two surfaces of the inner shell 200.

[0063] Please refer to Figure 2 and Figure 3 The mounting base 400 is covered on the inner shell 200, and the mounting base 400 and the inner shell 200 jointly close the slots of the hot end air duct 220 and the cold end air duct 210; the mounting base 400 is connected with two interfaces 410 with a distance therebetween, and the air inlet and the air outlet of the cold end air duct 210 are respectively connected to the inside of the medical refrigerator through the two interfaces 410, and the two interfaces 410 penetrate the thermal insulation foam 700.

[0064] Please refer to Figure 2 and Figure 3 A semiconductor cooling sheet 300 is provided at the intersection of the hot-end air duct 220 and the cold-end air duct 210 . The semiconductor cooling sheet 300 includes an integrally formed semiconductor heat dissipation fin 310 and a semiconductor cooling fin 320 . The semiconductor heat dissipation fin 310 is located inside the hot-end air duct 220 , and the semiconductor cooling fin 320 is located inside the cold-end air duct 210 .

[0065] Specifically, after the semiconductor refrigeration chip 300 is powered on, the temperature of the semiconductor cooling fins 320 decreases, and the temperature of the semiconductor heat dissipation fins 310 increases. When the air flow inside the medical refrigerator passes through the cold end air duct 210, the semiconductor cooling fins 320 cool the air flow, and the water vapor in the air flow condenses into liquid and is discharged from the inner shell 200 along the condensate drain pipe 211; the air outside the inner shell 200 enters the inner shell 200 through the hot end air duct 220, and continuously cools the semiconductor heat dissipation fins 310.

[0066] The hot-end air duct 220 and the cold-end air duct 210 are provided with a cross region, which can shorten the distance between the hot-end air duct 220 and the cold-end air duct 210, reduce the volume of the inner shell 200, and reduce the manufacturing cost of the dehumidification device.

[0067] The mounting base 400 can close the slots of the hot-end air duct 220 and the cold-end air duct 210 to maintain the airtightness of the hot-end air duct 220 and the cold-end air duct 210; since two interfaces 410 are provided on the mounting base 400, the cold-end air duct 210 can be well connected with the air inlet and outlet of the medical refrigerator through the two interfaces 410, and the gas can flow stably and orderly in one direction in the cold-end air duct 210, thereby ensuring an efficient dehumidification effect.

[0068] Please refer to Figure 2 and Figure 3 In some embodiments provided in the present application, the dehumidification module housing 100 covers the side of the inner housing 200 away from the mounting base 400, and the bottom of the dehumidification module housing 100 is provided with a condensate drain port 110 connected to the condensate drain pipe 211. Specifically, the dehumidification module housing 100 can protect the inner housing 200, and the dehumidification module housing 100 covers the cold end air duct 210, which can insulate the cold end air duct 210 to a certain extent, thereby improving the dehumidification effect of the dehumidification device.

[0069] Please refer to Figure 2 and Figure 3 In some embodiments provided in the present application, illustratively, there is a cavity between the dehumidification module shell 100 and the inner shell 200, and the inner shell 200 is provided with a foam injection port 230 communicating with the inside of the cavity, and the foam injection port 230 is provided with a sealing plug 231. It is easy to understand that after the dehumidification module shell 100 and the inner shell 200 are assembled together, the sealing plug 231 is removed, and the thermal insulation foam is filled into the cavity between the dehumidification module shell 100 and the inner shell 200 through the foam injection port 230. The thermal insulation foam completely occupies the cavity between the dehumidification module shell 100 and the inner shell 200, which can better insulate the cold end air duct 210 and further improve the dehumidification effect of the dehumidification device.

[0070] Please refer to Figure 2 and Figure 4 In some embodiments provided in the present application, for example, a cold end circulation fan 500 is provided in the cold end air duct 210, and the cold end circulation fan 500 is installed at the air inlet of the cold end air duct 210. A first mounting baffle 212 for clamping the cold end circulation fan 500 is also integrally formed in the cold end air duct 210, and the top, bottom, left and right sides of the cold end circulation fan 500 are provided with the first mounting baffle 212. Specifically, the first mounting baffle 212 can stably clamp the cold end circulation fan 500 in the cold end air duct 210, and when the cold end circulation fan 500 is in operation, it can accelerate the gas flow speed inside the cold end air duct 210 and the medical refrigerator, and enhance the dehumidification effect.

[0071] Please refer to Figure 2 and Figure 4 In some embodiments provided in the present application, for example, a hot end heat dissipation fan 600 is provided in the hot end air duct 220, and the hot end heat dissipation fan 600 is installed at the air outlet of the hot end air duct 220. A second mounting baffle 223 for clamping the hot end heat dissipation fan 600 is also integrally formed in the hot end air duct 220, and the top, bottom, left and right sides of the hot end circulation fan are provided with a second mounting baffle 223. Specifically, the second mounting baffle 223 can stably clamp the hot end heat dissipation fan 600 in the hot end air duct 220, and when the hot end heat dissipation fan 600 is in operation, the flow of the gas inside the hot end air duct 220 can be accelerated, and the cooling effect on the semiconductor heat dissipation fins 310 can be enhanced.

[0072] Please refer to Figure 2 and Figure 4In some embodiments provided in the present application, the inner shell 200 is exemplarily formed with a first filter 221 and a second filter 222, the first filter 221 is arranged at the air inlet of the hot end air duct 220, and the second filter 222 is arranged at the air outlet of the hot end air duct 220. Specifically, the first filter 221 and the second filter 222 can filter dust in the air entering the hot end air duct 220 to keep the hot end air duct 220 clean.

[0073] In summary, when the dehumidification device is powered on, the semiconductor refrigeration plate 300, the hot end heat dissipation fan 600 and the cold end circulation fan 500 operate simultaneously. After the semiconductor refrigeration plate 300 is powered on, the temperature of the semiconductor heat dissipation fins 320 decreases, and the temperature of the semiconductor heat dissipation fins 310 increases. The cold end circulation fan 500 causes the airflow to circulate back and forth between the cold end air duct 210 and the medical refrigerator. When the airflow inside the medical refrigerator flows through the cold end air duct 210, the semiconductor heat dissipation fins 320 cool the airflow, and the water vapor in the airflow condenses into liquid and is discharged from the inner shell 200 along the condensate drain pipe 211.

[0074] The hot end heat dissipation fan 600 allows the air outside the inner shell 200 to enter the inner shell 200 through the hot end air duct 220. The continuously flowing gas takes away the heat generated by the semiconductor heat dissipation fins 310, continuously cools the semiconductor heat dissipation fins 310, and the airflow continues to flow.
