Abstract
The invention relates to the technical field of airborne evaporation cycle refrigeration, in particular to an automatic condensate water discharging device of an onboard evaporator. The device comprises an evaporator shell, an evaporation draught fan, a ventilation pipe, a water drainage pipe and a valve body; a three-way structure is formed in an inner cavity of the valve body; and a valve plateis rotatably arranged in the inner cavity of the valve body. When the evaporation draught fan forms air exhaust negative pressure, the valve plate seals the lower end of the ventilation pipe and the lower end of the water drainage pipe; and when the evaporation draught fan does not work, the valve plate is in a free rotating state. By the adoption of the automatic condensate water discharging device of the onboard evaporator, electric energy is not consumed, the installation space on a machine is not increased, condensed water of the machine-mounted evaporator can be automatically discharged,the situation that condensed water is smoothly discharged out of the evaporator in a negative pressure environment is guaranteed, the influence of the negative pressure in the evaporator on condensedwater discharging is reduced, and the functional performance of the evaporator is improved; and meanwhile, the condensate water is prevented from entering a cabin due to unsmooth discharge to influence the safety of other equipment on an aircraft, and the comfort of passengers in the cabin is improved.
Description
technical field [0001] The invention relates to the technical field of onboard evaporative cycle refrigeration, in particular to an automatic discharge device for condensed water of an onboard evaporator. Background technique [0002] The evaporator is one of the four essential components of the airborne evaporative cycle refrigeration system. The evaporative refrigeration cycle technology is used to evaporate the refrigerant in the evaporator core to cool the air passing through the evaporator, and use the evaporator fan to The low-temperature air is sent to the cabin to achieve the purpose of cooling. In order to reduce the temperature and humidity of the air in the cabin, the evaporator must have sufficient cooling and dehumidification capacity. Due to the large pressure difference between the front and rear of the evaporator core, a negative pressure chamber is formed in the air duct from the back of the evaporator core to the blower, resulting in condensation. The wate...
