Specifically, in the vertical direction, the distance between the water pan 230 and the inner wall of the lower side of the main air duct housing 200 is half of the distance between the water pan 230 and the inner wall of the upper side of the main air duct housing 200.

Optionally, the air inlet 510 at the upper end of the outlet casing 500 is communicated with the air outlet at the lower side wall of the main air duct casing 200. Therefore, the air mixing airflow in the air mixing area 240 in the main air duct housing 200 flows into the air outlet housing 500 through the air outlet to be further mixed, the mixing effect of the heat exchange airflow and the non-heat exchange airflow is improved, and the mildness of the air outlet airflow is further improved.

Therefore, the inner wall of the rear side of the main air duct housing 200 is matched with the air outlet housing 500, and the occupied space and the production cost of the air outlet housing 500 are reduced.
Referring to fig. 10, in some embodiments, a method for controlling a duct structure of a medical cooler comprises:
s01, the processor obtains the internal environment temperature of the medical refrigerating box;
s02, the processor determines the temperature interval of the internal environment temperature;
and S03, controlling the opening and closing of the first air opening and the second air opening of the air duct structure by the processor according to the temperature interval of the internal environment temperature.
In the embodiment of the disclosure, by acquiring the internal environment temperature of the medical refrigerating box, the opening and closing of the first air port and the second air port of the air duct structure are controlled according to the temperature interval where the internal environment temperature is located, that is, the opening and closing of the heat exchange air duct and the circulation air duct in the air duct structure are selectively controlled according to the internal environment temperature of the medical refrigerating box, so that the internal environment temperature of the medical refrigerating box is better regulated, and the internal environment temperature uniformity is higher.
It can be understood that the temperature sensor is arranged in the medical refrigerating box, and the internal environment temperature of the medical refrigerating box is detected in real time through the temperature sensor.
Optionally, the processor controls the opening and closing of the first air opening and the second air opening of the air duct structure according to the temperature range of the internal environment temperature, and includes: under the condition that the internal environment temperature is in the first temperature range, the processor controls the first air opening to be opened and the second air opening to be closed, as shown in fig. 8; under the condition that the internal environment temperature is in the second temperature range, the processor controls the first air opening and the second air opening to be in an opening state, as shown in fig. 9; wherein the minimum value in the first temperature interval is greater than the maximum value in the second temperature interval. Thus, the internal environment temperature of the medical refrigerator is detected in real time through the temperature sensor, the processor obtains a detection result sent by the temperature sensor, and since the minimum value in the first temperature interval is larger than the maximum value in the second temperature interval, the first temperature interval belongs to a high-temperature interval, and the second temperature interval is in a low-temperature interval, when the internal environment temperature obtained by the processor is in the first temperature interval, the internal temperature of the medical refrigerator is higher at the moment, and rapid cooling is needed, the first air port is controlled to be opened, the second air port is controlled to be closed, so that all return air flows flow flows into the heat exchange air duct to exchange heat with the heat exchanger, and cold air flow after heat exchange is blown out of the medical refrigerator through the air supply port to rapidly cool the medical refrigerator; under the condition that the internal environment temperature obtained by the processor is within the second temperature range, the temperature inside the medical refrigerating box is lower at the moment, rapid cooling is not needed, the generation of a supercooling region is caused due to the fact that the air outlet temperature of the air supply opening region is lower, therefore, the first air opening and the second air opening are controlled to be in an open state, the return air flow part flows into the heat exchange air duct, the rest parts flow into the circulating air duct, and the temperature of the heat exchange air flow is neutralized by the non-heat exchange air flow, so that the temperature of the air flow blown out from the air supply opening is improved.

The switch assembly employs a conventional airflow switch structure in the art, and is not described herein.
Referring to fig. 11, in some embodiments, a method for controlling a duct structure of a medical cooler includes:
s01, the processor obtains the internal environment temperature of the medical refrigerator;
s02, the processor determines the temperature interval of the internal environment temperature;
s03, controlling the opening and closing of the first air opening and the second air opening of the air duct structure by the processor according to the temperature interval of the internal environment temperature;
s04, the processor acquires the working mode of the heat exchanger of the medical refrigerating box;
and S05, the processor controls the first air port and the second air port to be in a closed state under the condition that the heat exchanger operates in the defrosting mode.
In the embodiment of the disclosure, because the frosting phenomenon can appear on the surface of the heat exchanger after the heat exchanger in the heat exchange air duct works for a long time, the refrigeration effect of the heat exchanger is affected, so the heat exchanger needs to be defrosted, because the heat exchanger is in a heating state in the defrosting mode, the heat generated in order to avoid the defrosting of the heat exchanger flows into the medical refrigerator through the heat exchange air duct and the air supply opening, the refrigeration effect is affected, therefore, the processor acquires the working mode of the heat exchanger, and under the condition that the heat exchanger operates in the defrosting mode, the first air opening and the second air opening are controlled to be closed, the airflow flowing in the heat exchange air duct and the circulating air duct is blocked, the heat of the heat exchanger is prevented from flowing into the medical refrigerator, and the fluctuation of the internal environment temperature of the medical refrigerator in the defrosting of the heat exchanger is reduced.
It can be understood that the switching between the refrigeration mode and the defrosting mode of the heat exchanger is a conventional switching means of the existing refrigeration system, when the heat exchanger needs defrosting, the processor controls the four-way valve of the refrigeration system to reverse to enable the high-temperature and high-pressure refrigerant flowing out of the compressor to flow into the heat exchanger for defrosting, and the control logic of the processor about defrosting of the heat exchanger is not described herein again.
In some embodiments, the method for controlling the air duct structure of the medical cooler further comprises: the method comprises the steps that a processor obtains the end duration of a defrosting mode of a heat exchanger; the processor controls the first air opening to be opened under the condition that the ending time length is greater than or equal to the preset time length.
In the embodiment of the disclosure, after the defrosting of the heat exchanger is finished, the influence of defrosting heat on the heat exchange air duct and the surrounding environment is still far higher than the internal environment temperature of the medical refrigerating box, and the humidity in the heat exchange air duct is higher due to the water vapor generated by the defrosting, if the first air port is opened at the moment, the heat and the humid water vapor flow into the medical refrigerating box along with the air flow, so that the internal environment temperature and the humidity of the medical refrigerating box fluctuate, therefore, the first air port needs to be opened in a delayed manner after the heat exchanger finishes defrosting and carries out the refrigerating mode again, the inside of the heat exchange air duct and the surrounding environment thereof are pre-cooled and pre-dehumidified by the refrigeration of the heat exchanger, the processor obtains the finish time of the defrosting mode of the heat exchanger, and controls the first air port to be opened under the condition that the finish time is greater than or equal to the preset time, so that the fluctuation of the internal environment temperature and the humidity of the medical refrigerating box can be reduced, the refrigeration effect is improved.
It can be understood that, in order to meet the refrigeration requirement of the medical refrigerating box, the heat exchanger is switched to the refrigerating mode operation immediately after the defrosting mode operation is finished.
Specifically, the preset time duration is a preset time duration when the medical refrigeration box leaves a factory or a time duration set by a user according to actual needs, for example, the preset time duration is 4 minutes, and when the time duration when the defrosting mode of the heat exchanger is finished is greater than or equal to the preset time duration, it can be considered that the temperature and the humidity of the heat exchange air duct and the ambient environment thereof are reduced to a level with a small difference from the internal ambient temperature and the humidity of the medical refrigeration box.
