[0002] A turbocharger is a device that compresses air to improve the intake efficiency of an internal combustion engine. It is commonly used in internal combustion engines to improve combustion efficiency by compressing the intake air. The turbocharger is mainly composed of a turbine and a compressor, and the intake air is pressurized by the rotation of the turbine. However, since the turbocharger generates a large amount of high-temperature exhaust gas and friction heat during operation, it is easy to cause the turbocharger to overheat and be damaged, but at the same time it also has the risk of overheating. In order to protect the turbocharger from damage due to overheating, a turbocharger thermal protection device is often installed to prevent damage to the turbocharger and ensure the safety of the engine and vehicle.

[0003] However, due to the limitations of the working principle, the turbocharger will generate a lot of heat when running at high speed, which will increase the thermal stress of the turbocharger components and easily cause damage or even failure. In view of the above problems, the inventors proposed a turbocharger thermal protection device to solve the above problems. Utility Model Content

[0018] In this embodiment, driven by the pump 5, the coolant inside the cooling chamber 6 flows to the inside of the water outlet pipe 7, and is transported to the inside of the annular pipe 3 through the water outlet pipe 7. When passing through the inside of the casing 1, the heat generated by the turbine blades 2 during operation is absorbed, and finally flows back to the inside of the cooling chamber 6 through the return pipe 8.

[0019] A fixing plate 9 is fixedly connected to one side of the top of the mounting plate 4 close to the pump 5 , and a cooling fan 10 is fixedly mounted on one side of the top of the fixing plate 9 .

[0020] By adopting the above technical solution and setting up a cooling fan 10, when the coolant inside the cooling chamber 6 absorbs heat through the interior of the flow casing 1 and then flows back into the interior of the cooling chamber 6, the rotation of the cooling fan 10 is used to cool the coolant inside the cooling chamber 6.

[0021] A water injection pipe 11 is fixedly connected to one side of the top end of the cooling chamber 6 , and a sealing cover 12 is threadedly connected to the top end of the water injection pipe 11 .

[0029] Working principle: coolant is injected into the cooling chamber 6 by opening the sealing cover 12. When the temperature sensor 15 detects that the temperature of the turbocharger element is too high, the coolant in the cooling chamber 6 flows to the inside of the water outlet pipe 7 under the drive of the pump 5, and is transported to the inside of the annular pipe 3 through the water outlet pipe 7. When passing through the inside of the casing 1, the heat generated by the turbine blades 2 during operation is absorbed, and finally flows back to the inside of the cooling chamber 6 through the return pipe 8.
