The utility model provides a turbocharger and a turbine shell thereof. The turbine shell comprises a main airflow outlet and a bypass valve outlet. The partition wall is integrated on the inner wall of the turbine shell, a main flow channel is defined in the partition wall, a bypass flow channel is defined between the outer wall of the partition wall and the inner wall of the turbine shell, and the bypass flow channel and the main flow channel intersect at the highest point, close to an outlet of the turbine shell, of the partition wall; the bypass valve outlet is formed in the low point of the bottom of the bypass flow channel, and the bottom of the bypass flow channel rises around the outer wall of the partition wall in a gradient mode in the direction from the bypass valve outlet to the main airflow outlet. The bypass air flow gradually converges into the main air flow in parallel at the position far away from the turbine outlet, the influence of the bypass air flow on the main air flow can be reduced and
