Abstract
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. Including evaporator shell, evaporating fan, ventilation pipe, drain pipe and valve body; the inner cavity of the valve forms a three-way structure, and a valve plate is rotatably installed in the inner cavity of the valve; when the evaporating fan forms a suction negative pressure, the The valve plate closes the lower end of the ventilation pipe and the lower end of the drain pipe; when the evaporation fan is not working, the valve plate is in a state of free rotation. The device of the present invention does not consume electric energy, does not increase the installation space on the machine, and can realize the automatic discharge of condensed water from the on-board evaporator, ensuring that the condensed water can be discharged smoothly from the evaporator in a negative pressure environment, and reducing the impact of negative pressure in the evaporator on condensation. The impact caused by water discharge can improve the functional performance of the evaporator, and at the same time prevent the condensed water from entering the cabin due to poor drainage and affect the safety of other equipment on board, and increase the comfort of the cabin crew.
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...
