[0002] The engine base or supercharger needs to be continuously cooled during operation. The cooling water pipe is responsible for connecting the water pump assembly, thermostat assembly, supercharger, engine base and other functional units to provide a flow path for the coolant. The current conventional design schemes for cooling water pipes mainly include metal pipes and rubber pipes. Either of these two water pipes is used to accommodate the flow of coolant.

[0003] However, the designs of these two types of water pipes have certain disadvantages. Traditional metal pipes are limited by stamping design. Too many bending points will greatly affect the cost.

Rubber pipes require a larger layout space due to their larger outer diameter. In addition, due to the soft nature of the rubber pipe itself, fixed points need to be added in the middle section, which puts further requirements on the layout space. Utility Model Content
