Description
The technical field is as follows:
the invention relates to a pressure sensor cooling structure, in particular to a pressure sensor cooling device suitable for high-temperature environment testing.
The background art comprises the following steps:
the pressure is an important state parameter for representing the fluid mechanics characteristic of the object to be researched, and for the unsteady flow process, the state parameters of the working medium, such as the pressure, the temperature and the like, change along with the time and have the characteristic of dynamic change. At present, dynamic pressure is widely applied in the industrial production and scientific research fields, for example, pressure in internal combustion engines, gas turbines, steam turbines and rocket engines is basically dynamic, chamber pressure and explosion shock waves of firearms are dynamic pressure, and pulse pressure of hydraulic and pneumatic devices in various industrial control equipment and power machinery is also dynamic pressure. It is therefore necessary to carry out measurements of the dynamic pressure in order to study its hydrodynamic properties.
Since measurement of dynamic pressure generally requires a fast response time, common dynamic pressure sensors are mainly piezoelectric sensors and piezoresistive sensors. The silicon pressure sensor used in commercialization is mainly a silicon diffusion piezoresistive pressure sensor, the process is mature, the performance is excellent, the silicon diffusion piezoresistive pressure sensor is limited by the temperature resistance of a P-N junction, the pressure measurement can only be carried out below 120 ℃, the performance of the sensor can be seriously deteriorated to be invalid when the temperature exceeds 120 ℃, plastic deformation and current leakage can occur at 600 ℃, so that the extreme imbalance of a signal processing system and a circuit is caused, and the pressure measurement requirement in the fields of aerospace, power generation, petrochemical industry, automobiles and the like under the high-temperature environment can not be met. In addition, for the measurement of high-temperature combustion fluid working media, the pressure sensor has the problem of thermal shock, namely, during the combustion of fuel, the heat transferred to a sensing element of the pressure sensor is increased rapidly, so that the thermal shock occurs, and the deformation and the failure of the pressure sensor are caused.
The traditional dynamic pressure measurement of the fluid working medium in the high-temperature environment is mainly realized through a longer pressure guiding pipe, the heat of the high-temperature measured working medium is gradually dissipated after the high-temperature measured working medium passes through the pressure guiding pipe, and the temperature of the working medium is finally reduced to be lower than the maximum working temperature allowed by the stable operation of the sensor. The testing method is more suitable for measuring the dynamic pressure of the low-frequency pulsating fluid working medium, but for the high-frequency unsteady pulsating fluid working medium, after a longer pressure leading pipe is adopted, the amplitude-frequency and phase-frequency characteristics between the pressure signal measured by the sensor and the real pressure signal of the fluid working medium have larger difference, the measurement error is in direct proportion to the length of the pressure leading pipe, and the longer the pressure leading pipe is, the larger the measurement error is.
