While the cold and hot cavity air exchanges heat, the hot and humid air in the hot cavity changes phase, and the gaseous water changes into liquid water. The cooled hot cavity condensate enters the water separator with the airflow, the water separator separates the water and the air, and the separated water is discharged from the machine body through the pipeline. Generally, the water separator is installed at the outlet end of the condenser hot cavity. Because the cold cavity inlet air temperature of the condenser is reduced, in order to increase the cold cavity outlet air temperature to the specified temperature, a reheater is generally arranged at the cold cavity inlet end of the condenser. In order to realize the specified temperature of the condenser cold cavity outlet and the drainage function of the hot cavity outlet, a reheater needs to be added at the hot and cold cavity inlet end of the condenser. A water separator is added at the hot cavity outlet end of the condenser, and related connecting pipelines also need to be added. Thus, the weight of the airplane is increased, the space size of the airplane is also increased, and the cost of the airplane is also increased. SUMMARY

[0004] The utility model discloses a kind of airborne condenser device with cabin air mixing function and drainage function, including shell and the radiator core being arranged in shell, the radiator core is provided with cold flow channel and hot flow channel for realizing heat transfer, it is characterized in that, the shell includes inner cylinder and outer cylinder, the outer cylinder top is provided with cold air inlet, and the outer cylinder bottom is provided with cold air outlet;

[0007] The inner cylinder is located on the upper part of the outer cylinder, and one end of the inner cylinder is sealed and fixedly connected to the inner ring surface of the outer cylinder near the cold air inlet. The other end of the inner cylinder is sealed and fixedly connected to the inner ring surface in the middle of the outer cylinder. One end of the inner cylinder is connected to the cold air inlet, and the other end of the inner cylinder is connected to the area where the radiator core is located in the outer cylinder.

[0008] An air intake channel is provided between the upper part of the inner cylinder and the outer cylinder, and the air intake channel is connected to the internal area of ​​the inner cylinder through a connecting hole provided on the circumference of the inner cylinder.

[0015] This invention features a simple structure. It utilizes an annular airflow channel formed by the inner and outer cylinders to uniformly mix the constant-temperature air and cold air entering the condenser's heat dissipation core. After heat exchange within the heat dissipation core, the hot air is cooled, and the gaseous water in the hot air condenses into liquid water. Driven by the airflow, the liquid water is blown towards the inner wall of the water separator cavity and the arc-shaped baffles inside the cavity. The liquid water adheres to these walls and flows downwards under gravity. Furthermore, the bottom of the water separation cavity is spherical, with a drain connector located at the lowest point of the sphere. This allows the condensed liquid water to collect and flow into the drain connector, exiting the condenser. This maximizes energy efficiency and saves costs. Attached Figure Description
