To certain temperature, meet requirement of experiment, then air-flow completes test function, but air-flow stream in experimentation into wind tunnel noumenon is crossed
Measure constant, only consume part kinetic energy and thermal energy, then, air-flow outflow wind tunnel noumenon, during by wind-tunnel heat exchanger, by partial heat energy
Change the tunnel airstream to the low temperature for having just enter into wind-tunnel heat exchanger.After wind-tunnel heat exchanger, air-flow is discharged into air.The program
When only realizing wind-tunnel work, the recycling of after-heat in air-flow, and after can not realizing that wind-tunnel is stopped, remained in heater
The recycling of excess heat.Remaining heat is suitable with the heat consumed during wind tunnel operation in wind tunnel heater, but in current wind
In the design of hole, in order to protect heater, after the test, the mode of generally use ventilation cooling, by the heat in heater
It is discharged into air and dissipates.
