Description
Technical field
The utility model relates to a kind of heat flux sensor, relates in particular to water cassette heat flux sensor.
Background technology
Water cassette heat flux sensor, its ultimate principle is that heat passes to test water by central sensitive surface, causes test water temperature rise.The effect of water-cooled protective cover makes to prevent the side direction heating of high temperature gas flow to water cassette heat flux sensor, reduces side direction heat interchange.Using sensitive surface as research object, enough little in wall thickness, wall surface temperature changes in little situation, ignore the impact of wall internal thermal resistance, think that Aerodynamic Heating heat has all passed to the test water in water cassette sensor, can think that to the impact of test water heat transfer the heat that transmits feedwater cassette heat flux sensor sensitive surface equals the heat that water cassette sensor water absorbs if ignore other walls.Like this, predicting rate of flow of water, sensitive surface area, measuring under the prerequisite of water physical property, just can be poor with test water out temperature, calculate the heating hot-fluid of sensitive surface.Current water cassette sensor, complex structure, and central sensitive surface easily absorbs inner wall temperature, and heat exchange is carried out in side, causes metering inaccurate.
Utility model content
The utility model, for the defect of prior art, has proposed a kind of water cassette heat flux sensor, simple in structure, the mode that adopts measurement water and chilled water to separate, accurate measurement.Chilled water has large chamber, can effective cooling.Visit core and adopt oxygen-free copper, heat transfer efficiency is high, and hot conduction eror is little.
A kind of water cassette heat flux sensor, comprising:
