Special external safety air duct for special vehicle

Abstract

The invention discloses a special external safety air duct for a special vehicle. The special external safety air duct for the special vehicle comprises an air duct main body; the air duct main body is a cavity structure consisting of a bottom shell and a housing; an air inlet is formed in the bottom shell; a plurality of air outlets are formed in the housing; the air inlet and the air outlets arestaggered from each other; the special external safety air duct for the special vehicle further comprises an internal heat insulation board and an air guide plate; the internal heat insulation boardfits the internal walls of the bottom shell and the housing; the air guide plate divides the cavity structure into a plurality of air guide areas; each air guide area is correspondingly in communication with one or more air outlets; and each air guide area is in communication with the air inlet. According to the special external safety air duct for the special vehicle, as the heat insulation boardis arranged in the air duct, the outside hot air is isolated from cold air during using an air conditioner refrigeration mode so that condensed water generated on the external wall of the air duct isavoided; and through adoption of the air guide plate, the air outlet volume of each air outlet is uniform so that the loss of air energy is reduced.

Description

technical field [0001] The invention relates to the field of automobile air-conditioning air ducts, in particular to an external safety air duct dedicated to special vehicles. Background technique [0002] The cockpits of some special vehicles are larger and have more instruments inside, and the air-conditioning ducts are mostly arranged on the upper part of the instrument assembly to achieve better cooling or heating effects. All the air outlets of the conventional air duct are connected to each other through the air duct, and the air after the heat exchange of the air conditioner reaches each air supply outlet respectively through the air inlet of the air duct. There is less wind, and the air from each air outlet is uneven, resulting in a large loss of wind energy, reducing the efficiency of the air conditioner, and increasing energy consumption; If the temperature is relatively high, the temperature of the air cooled by the air conditioner in the air duct is relatively l...
