Tandem type forced cooling pressurization system

The utility model belongs to the field of automobile cooling systems, and particularly relates to a tandem type forced cooling pressurization system which comprises a pressurizer, a water inlet pipeline connected with the water inlet side of the pressurizer, a water return pipeline connected with the water outlet side of the pressurizer, an electronic water pump and an engine main water pump. Theelectronic water pump is arranged on the downstream of the engine main water pump in series in the flowing direction of cooling liquid. According to the turbocharger rotor system, the temperature of the turbocharger rotor system is reduced, and the problems of high-temperature coking and the like of the turbocharger rotor system caused by frequent starting and stopping of an engine and special application of hybrid power are solved. 本实用新型属于汽车冷却系统领域，具体是一种串联式强制冷却增压系统，包括增压器，连接所述增压器的进水侧的进水管道，连接所述增压器的出水侧的回水管道，电子水泵和发动机主水泵，所述发动机主水泵设置在所述进水管道上；沿着冷却液的流动方向看，在所述电子水泵串联设置在所述发动机主水泵的下游。本实用新型降低了涡轮增压器转子系统温度，解决了发动机频繁启停、混合动力特殊应用带来的增压器转子系
