In this case, in order to ensure the tightness of the fluid flow, a fifth seal ring 1226 needs to be added when the second hose connector 1223 is connected to the nylon tube or the rubber tube, and a fourth seal ring 1225 needs to be added when the third hose connector 1224 is connected to the nylon tube or the rubber tube.

The flow direction of the pipeline and the cooling liquid in the cooling system can be changed through the changing arrangement of the number of the hose connectors in the embodiment. Therefore, by changing the amount of the hose connector or changing the included angle between the hose connector and the opening end of the first body, different types of connector assemblies can be provided to meet different installation requirements.
