The invention relates to the technical field of automobile heating, ventilation and air conditioning systems, in particular to an air inlet box shell with a double-drainage structure, a heating, ventilation and air conditioning assembly and a vehicle. The air inlet box shell comprises an air inlet box upper shell and an air inlet box lower shell, the air inlet box upper shell is fixedly connected with the air inlet box lower shell, and an outer circulation air opening is formed in the air inlet box upper shell; an air inlet channel, an air conditioner filter element mounting structure, an air blower assembly mounting structure and an evaporator assembly mounting structure are arranged on the air inlet box lower shell, the air inlet channel is communicated with the outer circulation air opening, and an air inlet channel drainage structure is arranged at the air conditioner filter element mounting structure. And an evaporator drainage structure is arranged at the evaporator assembly mounting structure. Water in the air inlet box of the heating ventilation air conditioner can be more completely discharged, the situation that microorganisms such as mould breed in the shell due to water accumulation is effectively avoided, and the problem that an air blower, a speed regulation module and other electric devices are damaged due to water inflow can also be effectively avoided.

    本发明涉及汽车暖通空调系统技术领域,尤其涉及一种带双排水结构的进风箱壳体、暖通空调总成及车辆,包括进风箱上壳体和进风箱下壳体,所述进风箱上壳体与进风箱下壳体固定连接,所述进风箱上壳体上设置有外循环风口,所述进风箱下壳体上设置有进风风道、空调滤芯安装结构、鼓风机总成安装结构和蒸发器总成安装结构,所述进风风道与外循环风口连通,所述空调滤芯安装结构处设置有进风道排水结构,所述蒸发器总成安装结构处设置有蒸发器排水结构。本发明能够更加完全的对暖通空调进风箱内的水进行排出,有效避免水的堆积导致壳体内出现霉菌等微生物滋生的情况,也可以有效避免鼓风机、调速模块等电器件因进水导致的损坏问题。
