Abstract

The invention relates to a turbine supercharger. The turbine supercharger with a cooling water jacket comprises a turbine motor shaft, a turbine motor turbine, and a turbine motor scroll, wherein the turbine motor is installed on the turbine motor shaft, the turbine motor turbine shell covers outside the turbine motor turbine shell, an air inlet and an air outlet are formed in the turbine shell, the water jacket is arranged inside the turbine motor turbine shell, a water inlet and a water outlet are formed in the water jacket, the water inlet is placed in one side, facing the air outlet, of the water jacket, and the water outlet is placed in one side, facing the air inlet, of the water jacket. The turbine supercharger where the water jacket is installed on the turbine motor turbine shell, and water inside the water jacket and the turbine motor turbine shell can conduct highly-efficient heat exchanging resolves the problems that effective use ratio of fuel oil is low and light materials being used in the turbine motor turbine shell for manufacture is restricted because of high temperature of the turbine motor, the fact that the light materials cannot be adopted in the turbine motor for manufacture can cause that the turbine exchanger is weight, and therefore the effective work of a motor is lowered.

Description

technical field

[0001] The invention relates to a turbocharger, in particular to a turbocharger with a cooling water jacket, and belongs to the technical field of engines. Background technique

[0002] At present, the turbocharger generally requires that the exhaust temperature of the engine should not be too high due to the limitation of the turbine volute structure and material (generally high-nickel cast iron or high-nickel stainless steel). The current turbocharger turbine volute material is high-nickel cast iron or stainless steel, the temperature resistance can reach 950°, and the material density is 7.8g / cm3. The exhaust temperature of the engine directly affects the effective utilization of fuel. When the engine is at low speed, high load and high speed, the temperature in the engine cylinder will be very high. Because the existing turbocharger cannot effectively reduce the temperature of the turbine, and The temperature that turbocharger and other components can w...
