Problems solved by technology
The problem with this device is that the heat flow provided by the high-temperature graphite plate is a static heat flow, which cannot be dynamically changed at a certain frequency. In practical applications, the calibration heat flow is often dynamic, so this method can only calibrate the static heat flow. Can not meet the requirements of the actual working conditions of heat flow

Description
technical field [0001] The invention mainly relates to the technical field of heat flow sensors, in particular to a heat flow sensor calibration device. Background technique [0002] Heat flow testing is widely used in thermal protection system design of aerospace weapons and equipment, aerodynamic thermal profile design and thermal engineering kiln heat transfer design. The application of heat flow testing tends to be the actual working conditions of dynamic heat flow testing. The sensor calibration device provides symmetrical heat flow on both sides of the specially processed high-temperature graphite plate. The standard heat flow sensor and the experimental heat flow sensor are placed in symmetrical positions. The calibration of the experimental heat flow sensor is completed by comparing the signal output of the standard heat flow sensor and the experimental heat flow sensor. The problem with this device is that the heat flow provided by the high-temperature graphite plat...
