Three-way pipe for parallel thermal management system of hydrogen energy vehicle

The utility model discloses a three-way pipe for a parallel thermal management system of a hydrogen energy automobile, which is characterized in that the sectional area of an inlet end of the three-way pipe is smaller than the sum of the sectional areas of two outlet ends of the three-way pipe, and the sectional areas of the two outlet ends are the same. The separation sections of the two outlet ends and the inlet end are in smooth transition through involutes, the involutes on the two sides are tangent to the outer wall of the inlet end and the outer wall of the outlet end, and the axis angle a of the two outlet ends ranges from 100 degrees to 120 degrees. Cooling liquid is stable when entering and exiting the three-way pipe, vortex of the cooling liquid is prevented from being generated in a separation section, and the cooling liquid is evenly distributed. 本实用新型公开了一种用于氢能汽车并联热管理系统中的三通管.本实用新型的一种用于氢能汽车并联热管理系统中的三通管，三通管的进口端的截面积小于其两个出口端的截面积之和，两个出口端的截面积相同，两个出口端与进口端的分离段以渐开线平滑过渡，两侧渐开线与进口端外壁和出口端的外壁均相切，两个出口端的轴线角度a为100
