Description

Cooling device of gasoline octane number tester Technical Field The utility model belongs to the technical field of gasoline octane number measurement, and particularly relates to a cooling device of a gasoline octane number measuring machine. Background The gasoline octane number tester is one instrument for measuring the antiknock performance of gasoline and is used mainly in evaluating the octane number of gasoline. Octane number is an important index for measuring the anti-knock capability of gasoline in an engine, and directly influences the performance and fuel economy of the engine. The gasoline octane number tester typically performs the test by preparing a sample by adding a sample of gasoline to be tested to a test vessel. Ignition, namely igniting the gasoline sample in a controlled environment. Pressure monitoring, namely monitoring pressure waves generated in the combustion process through a pressure sensor and analyzing the characteristics of the pressure waves. And (3) calculating the octane number of the gasoline according to the intensity and duration of the pressure wave. And outputting the result, namely displaying the measurement result on a screen for recording and analyzing by an operator. In the gasoline combustion process, the generated high-temperature gas often contains a certain amount of dust and solid particles. These particulate materials not only pollute the environment but may also adversely affect the proper operation of the device. When these high temperature gases are cooled directly through the cooling pipe, dust and solid particles are liable to adhere to the inner wall of the cooling pipe, forming dirt deposits. The deposition phenomenon can result in a reduction in cooling efficiency, namely, dust accumulation in the cooling pipe can increase thermal resistance, reduce the effective heat exchange area between the cooling liquid and the gas, and further reduce the cooling efficiency, and influence the normal working temperature of the equipment. The maintenance difficulty increases in that once dust adheres to the inner wall of the cooling tube, the cleaning work becomes complicated and time-consuming. Conventional cleaning methods may have difficulty thoroughly removing accumulated dirt, resulting in increased maintenance costs of the equipment. Therefore, in order to solve the problem of dust adhesion in high-temperature gas generated by gasoline combustion, it is highly desirable to develop an effective cooling device capable of reducing adhesion of dust and solid particles while ensuring cooling efficiency, thereby improving reliability of equipment and convenience of maintenance.
