For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of engine water pump cap assembly, described engine water pump includes water pump seat and water pump cover, and described water pump seat is provided with impeller；Described water pump cover is provided with intake tunnel and exhalant canal, and described intake tunnel and described exhalant canal one-body molded by water pump cover；
Wherein, described intake tunnel includes a main channel, and this main channel is lying on described water pump seat, and the head end of main channel is coolant the first entrance, the end of main channel bends and covers on the impeller installation cavity of described water pump seat, constitutes " L " shape that described main channel is accumbency；
Described intake tunnel the most also includes one first subchannel, and this first subchannel is opened in the middle part of main channel, and its entrance is coolant the second entrance；
Described exhalant canal connects setting with described impeller installation cavity.
Relevant content in technique scheme is explained as follows:
1. in such scheme, the systemic circulation path of described main channel connection automobile cooling system, i.e. the coolant pipeline of the outside chiller of connection, import the coolant through outside chiller cooling.
3. in such scheme, the partial circulating path of described coolant the second entrance connection automobile cooling system, i.e. connect the cylinder body of electromotor and the coolant pipeline of cylinder cap, import cylinder body and the coolant of cylinder cap of electromotor.
2. in such scheme, described intake tunnel also includes the second subchannel, and this second subchannel is opened in the bending place of described main channel, and the entrance of the second subchannel is arranged obliquely, for coolant the 3rd entrance.Described coolant the 3rd entrance connection cabin temperature control system, imports the coolant of cabin temperature control system.
Operation principle of the present utility model and advantage are as follows:
This utility model one engine water pump cap assembly, integrally formed with intake tunnel and go out water passage.Wherein intake tunnel includes " L " shape main channel, and the head end of this main channel is coolant the first entrance, the impeller installation cavity of the end connection water pump seat of main channel；And at least one first subchannel, it is opened in the lower section of main channel, for coolant the second entrance.Designing whereby, this utility model solves the more problem causing cost height and being easily caused coolant leakage of prior art part, has processing technique simple, the advantage that dependability is high.
