Wherein, R is the latent heat of vaporization of the water at 100Kpa, 0 DEG C, value 2500kJ/kg；
3) heat loss for considering PTC heating sheet, under the premise of insulation fully sheathed case carries out insulation, the value of n is 95%；
4) water generates saturated steam by absorbing the latent heat of vaporization, and the Thermal plume of hot-air adds the guide functions of blower around
Under, by escape pipe will be insulated the saturated steam that fully sheathed case generates be sent to dummy it is external in, so far entire human body dissipates wet mistake
Journey is completed；
5) for setting different moisture dispersed amounts, the corresponding voltage of PTC heating sheet controls light solid-state relay by PTC controller
Switch, passes through duty cycle adjustment PTC heating sheet required voltage.
11. what integration simulation human-body radiating according to claim 10 dissipated wet dummy's device dissipates wet method, feature
It is, the use environment of dummy's device requires as follows in this method:
A) air pressure: 90kPa-110kpa；
B) temperature: 0 DEG C -40 DEG C；
C) humidity: 10%R.H.-90%R.H.
12. integration simulation human-body radiating according to claim 1 dissipates the heat dissipating method of wet dummy's device, feature exists
In including the following steps:
1) according to the heating power P of setting, heat production controller is controlled by 485 signals that host computer exports, light is controlled with this
The switch of solid-state relay passes through the heat radiation power P of duty cycle adjustment dummy；
2) in entire radiation processes, manikin surface reaches the shape of a heat production and heat dissipation balancing by lasting heating
State；3) the actual power P1 that dummy is acquired by electric energy meter is adjusted by PID so that P1 is continuous with P according to the difference of P1 and P
Close to until identical.
