Front steam assembly of automobile air conditioner system

Abstract

The invention discloses a front evaporator assembly of an automotive air conditioner system. According to the front evaporator assembly, connection is carried out in a screw screwing manner after snapping buckles of a connecting air passage and an inlet air box shell are damaged; left and right shells are connected through surrounding bolts and middle bolts running through middle mounted columns of the left and right shells; a first longitudinal air outlet and a second longitudinal air outlet in the left and right shells are connected through a first horizontal connecting rib, and a third longitudinal air outlet is connected with a first edge of a right gap through a second horizontal connecting rib; wrong-mounting preventing marks are arranged on a face blowing and frost removing throttle rocking arm, the right shell close to the face blowing and frost removing throttle rocking arm, a mixing throttle rocking arm and the right shell close to the mixing throttle rocking arm. The front evaporator assembly has the advantages that the condition that the connecting air passage is rejected in advance due to a damaged snapping buckle is avoided, the occurrence of the wrong mounting of the face blowing and frost removing throttle rocking arm and the mixing throttle rocking arm is prevented, the deformation of gaps at outlets of the left and right shells during machining and use is prevented, and the reliability of the assembling of the left and right shells is improved.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a structure of a front evaporator assembly of a vehicle air conditioner. Background technique [0002] The evaporator assembly (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, convert it into vapor and absorb the cooled medium heat, 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] The front evaporator assembly (referred to as the front evaporator assembly) is composed of the connecting air duct, the air intake box shell, the upper and lower shell components and the left and right shell components connected...

AI Technical Summary

Problems solved by technology

During the maintenance process, the connecting air duct needs to be disassembled, which is likely to cause damage to the buckle of the connecting air duct, causing the connecting air duct to be scrapped and unable to continue to be used

As for the connecting air duct, except for the buckle damage, the rest of the parts are intact, resulting in great waste

[0005] In addition, since the rocker arm of the blowing surface defrosting door and the rocker arm of the mixing air door are very similar in structure, but the two cannot be installed interchangeably, therefore, during assembly, workers are likely to mix the rocking arm of the blowing surface defrosting door and the mixing door The rocker arm is installed incorrectly, causing the front steamer assembly to fail to work normally. It must be disassembled and reinstalled, which is very troublesome and will leave a bad impression on consumers
