Description
Technical Field
The utility model is applied to the technical field of demisting and wind increasing of automobiles, and particularly relates to a multifunctional flow guiding device of a pure electric bus.
Background
At present, a domestic pure electric bus is generally defogged through an electric heating defroster arranged in an instrument desk or a front wall, and the defogging principle of the electric heating defroster is that an electric heating plate heats air in the bus and then directly blows the air to a front windshield, namely, the fog on the front windshield is blown dry by hot air. The reason for the fog of the front windshield in the automobile is that the temperature outside the automobile is much lower than the temperature inside the automobile, and the inner side of the front windshield generates water fog under the combined action of the larger temperature difference and the higher air humidity. If the electric defrosting machine is used, demisting efficiency is low, energy consumption is high, and comfort of a driver or a passenger is reduced.
Part manufacturers design an air conditioner air outlet on the front top, and the defogging function is achieved by directly blowing the front baffle glass with the cool air of the air conditioner. Because the air outlet of the blower of the air conditioner is generally arranged in the air duct of the middle section or even the rear section of the carriage, and the pipeline and the parts installed in the air duct are blocked, the air outlet of the front ejection air outlet is smaller, and the demisting effect is also directly reduced. In order to increase the demisting effect, a driver can adjust the air outlet of the air conditioner to the maximum. The operation can not only increase the energy consumption of the whole car, but also improve the noise of an air conditioner blower and the air output of cool air in a carriage, and seriously affect the comfort.
Part of pure electric buses often cause poor refrigerating effect of the air conditioner of the driving position due to the fact that the overhead air conditioner is installed too far back. The driver can reduce the air conditioner refrigerating temperature or increase the air output of the air conditioner to improve the comfort and improve the refrigerating effect of the driving position. This can result in excessive cooling capacity, excessive temperature, and reduced comfort in the passenger compartment. In order to inject fresh air into a carriage and ensure the freshness of the air in the carriage, a ventilation fan is generally arranged on a vehicle roof. The air inlet of the ventilating fan is connected with the outside of the vehicle, the air outlet is connected with the inside of the carriage, and outside air is directly injected into the inside of the carriage during working. For vehicles with more than 8 meters, the ventilation of 1 ventilator is not uniform, and 2 or more ventilators are required to be installed to achieve the effect of uniform ventilation in the carriage. The installation of a plurality of ventilation fans can increase the cost of the fresh air function, and occupy more roof space, so that the flexible arrangement of roof parts is not facilitated. Therefore, the multifunctional flow guiding device of the pure electric bus, which has the advantages of simple structure and capability of realizing air-conditioning air defogging, external circulation air defogging and fresh air function, is necessary.
