Radiator assembly of a hybrid electric bus

Abstract

The invention discloses a radiator assembly for a hybrid electric bus. The radiator assembly comprises a motor and controller cooling radiator, an engine cooling radiator, a supercharging intercooler and a cooling fan, wherein the motor and controller cooling radiator and the engine cooling radiator are connected in the same row; the supercharging intercooler is arranged outside the motor and controller cooling radiator and the engine cooling radiator; the engine cooling radiator is close to a hot end of the supercharging intercooler; the motor and controller cooling radiator is close to a cold end of the supercharging intercooler; and the cooling fan is arranged inside the motor and controller cooling radiator and the engine cooling radiator. Since the circulating water passages of the two radiators are independent of each other, the cooling effects of an engine and a motor and controller cooling system are enhanced, and the work and the life of the radiator assembly are guaranteed; and thus, the problem of arrangement of the radiator assembly in an engine driving cabin of the hybrid electric bus is solved.

Description

technical field [0001] The invention relates to the field of bus auxiliary accessories, in particular to a radiator assembly of a hybrid electric bus.
