The invention discloses a hybrid electric vehicle cooling system arrangement mode and a control method, and belongs to the technical field of automobile cooling systems. The arrangement mode comprises an engine cooling loop, a motor electric control cooling loop, a DHT cooling branch, a high-voltage battery cooling branch, a cab cooling loop and a cooling device. The control method utilizing the arrangement mode of the cooling system of the hybrid electric vehicle comprises a cab cooling loop and high-voltage battery cooling branch control method, an engine cooling loop control method and a motor electric control cooling loop and DHT cooling branch control method. According to the method, cooling pipelines of the DHT hybrid power automobile are arranged to be combined with an effective control method for components, a transmission, a motor electric controller and a battery are preheated through cooling water, so that the whole system rapidly reaches the optimal temperature, then the motor electric controller, a hybrid power gearbox and the battery are preheated, all the systems can be rapidly warmed up, the working efficiency of the whole system is improved, and the service life of the system is prolonged. And the economical efficiency of the hybrid electric vehicle is further improved, and emission is reduced.
