Description

Condenser assembly and refrigerating device for airplane Technical Field The invention belongs to the technical field of air conditioning, and particularly relates to a condenser assembly and a refrigerating device for an aircraft. Background The cooling device of the aircraft galley is an important component part of the aircraft auxiliary cooling system, but frost formation on its heat exchanger (condenser) during its operation has always been a focus problem for its design. The defrosting design of the cooling device of the existing aircraft kitchen dining car mainly focuses on two aspects, namely, how to collect defrosting water to the greatest extent and reduce water vapor from entering an air supply pipeline, and the influence on the collection of the defrosting water when the aircraft is inclined is reduced, for example, when the aircraft ascends or descends to a stage or turns, the airframe can incline, and at the moment, the collection of the defrosting water can be difficult. The structure for collecting the defrosting water of the prior aircraft kitchen cooling device mainly comprises a strip-shaped water collecting tank which is arranged by a gas inlet of the device, wherein the defrosting water drips into the water collecting tank from a heat exchanger and is collected to a drain pipe along the gravity direction under the action of falling film flow, but the effect of collecting the defrosting water is influenced by the flight inclination angle of the aircraft, and when the inclination angle of the aircraft is slightly larger and opposite to the inclination direction of a chute, the effect of collecting the defrosting water is poor.
