Air outlet flow equalizing plate of automotive air conditioning evaporator

Abstract

The invention discloses an air outlet flow equalizing plate of an automotive air conditioning evaporator. The air outlet flow equalizing plate is of an injection-molding plate body structure, wherein a first ventilation hole region (1) and a second ventilation hole region (2) are formed in a plate body, ventilation holes in the first ventilation hole region (1) are larger than those in the second ventilation hole region (2), a limiting column (3) is arranged on one side of the plate body, and the axis of the limiting column (3) is parallel to a plate body plane. The ventilation holes in the flow equalizing plate are formed in different regions, and the ventilation holes in different ventilation hole regions are different in size. When the air outlet flow equalizing plate is installed, one side where the ventilation holes are large is installed on the side where the air speed is high, one side where the ventilation holes are small is installed on the side where the air speed is low, and the air outlet flow equalizing effect is achieved. The front end of the air outlet flow equalizing plate is clamped in installing grooves correspondingly formed in a right casing and a left casing, meanwhile a plug hole is formed in the right casing, and the limiting column is inserted into the plug hole to achieve positioning during installation, so that an installing structure is simplified.

Description

technical field [0001] The invention belongs to the technical field of vehicle air-conditioning devices, and in particular relates to a structure of an equalizer plate at an air outlet of a vehicle air-conditioning evaporator. Background technique [0002] The evaporator (abbreviated as NBM1) is a crucial component in the automotive air-conditioning system, which has a significant impact on the cooling effect of the air conditioner. It uses liquid low-temperature refrigerant to evaporate easily at low pressure, transforms into vapor and absorbs the heat of the cooled medium , so as to achieve the purpose of cooling. The vehicle air conditioner evaporator is divided into a front evaporator assembly and a top evaporator assembly according to the installation position in the vehicle. [0003] Such as figure 1 The front evaporator shown is composed of connecting air duct A, air intake box shell E, upper and lower shell components B, left and right shell components C, etc. conn...
