Abstract

The invention relates to a ventilating device for a vehicle cab. The device comprises an air guide pipe, an air quantity regulating device positioned in the air guide pipe, an air outlet device and an air conditioning evaporator, wherein the inlet end of the air guide pipe is provided with an interface which protrudes out of a vehicle body coaming of the cab; the interface is connected with the air outlet of the air conditioning evaporator by pressing or sleeving; the tail end of the air guide pipe is connected with the air outlet device by pressing or sleeving; the air guide pipe is arranged on a vehicle body framework of the cab; and the air outlet direction of the air outlet of the air outlet device can be adjusted. The device can improve the ventilating stability and smoothness of the vehicle cab, ensures that a temperature and humidity in the vehicle cab are uniform, enhances an air conditioning effect, and reduces energy consumption, noise in the cab, production cost and using cost.

Description

technical field [0001] The invention belongs to the technical field of vehicle heating, cooling or ventilation equipment, and in particular relates to a ventilation device for an air-conditioning system in a vehicle cab. Background technique [0002] In order to improve the operating environment, in some trucks and construction machinery, the cab is equipped with an air-conditioning system. Generally, the air is blown directly from the evaporator of the air conditioner, which may cause uneven air temperature in the cab, and local wind speed is too high. Special requirements such as glass defrosting cannot be met. Some vehicle cab air-conditioning systems are also provided with air ducts to send air to ideal areas, but most of the air ducts are arranged in vehicle interior parts, such as Chinese patent application No. CN200620071300.X, named "Automobile The utility model patent of "Interior Luggage Rack" discloses a structure of an automobile air duct: it includes: an air-co...
