car air conditioner

Abstract

An automobile air conditioner comprises an outer housing (1) and a chassis (2). An inner unit area (21) for mounting an inner unit and an outer unit area (22) for mounting an outer unit are located in a space between the outer housing (1) and the chassis (2). The outer housing (1) is provided with an air inlet, the air inlet having a water retaining structure. An air outlet is provided at an end portion, close to the outer unit area (22), of the chassis (2). An outer housing of the air conditioner is provided with an air inlet, the air inlet area can be increased, and the condensation pressure is reduced. Meanwhile, heat dissipation of a compressor of an outer unit area is facilitated. Moreover, the air inlet of the outer housing is provided with the water retaining structure, and is capable of preventing rain and high-pressure automobile washing water from entering an electrical appliance box part of the outer unit area. An air outlet of a chassis is away from the air inlet of the outer housing, so hot air reflowing cannot be caused.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a vehicle air conditioner. Background technique [0002] Facing the harsh vehicle environment, the general vehicle air conditioner needs to have functions such as rain protection and car washing spray on the premise of ensuring stable performance and reliable quality of the whole machine. The outer casing of the existing vehicle-mounted air conditioner adopts a sealing method, and the air enters from the chassis, and the air is discharged on both sides of the rear part of the chassis. The disadvantageous effects brought by the above-mentioned settings are: [0003] 1) The air inlet area is small, resulting in too high condensation pressure, which has a great impact on performance; [0004] 2) Due to the airtightness on both sides of the shell, it is not conducive to the heat dissipation of the compressor, which also affects the performance; [0005] 3) The air enters from the ch...

AI Technical Summary

Problems solved by technology

[0003] 1) The air inlet area is small, resulting in too high condensation pressure, which has a great impact on performance;

[0004] 2) Due to the airtightness on both sides of the shell, it is not conducive to the heat dissipation of the compressor, which also affects the performance;

[0005] 3) The air enters from the chassis, and the air exits on both sides of the rear of the chassis. If the distance between the air inlet and the air outlet is too close, the air intake will be affected, resulting in hot air backflow
