Male warm body dummy

Product description.

The human body, in addition to heat dissipation to the surrounding environment through conduction, convection and radiation, also loses heat through the evaporation of sweat on the surface of the human skin. If the water vapor can be spread to the surrounding environment through the clothing system in time, people feel comfortable, if the clothing hinders the passage of water vapor, so that the humidity in the microclimate between human skin and clothing increases, water vapor will accumulate to a certain extent and condense into water, making people feel uncomfortable. When the human body for strenuous activities or in a hot environment, the evaporation of sweat becomes an important way for the body to lose heat, at this time more requirements for clothing with sufficient water vapor transfer capacity. It follows that it is necessary to accurately test the evaporation resistance of the garment in order to make a comprehensive evaluation of the heat and moisture transfer performance of the garment.

The dummy can test a detailed data system and the dummy itself does not come with fingers and face. The dummy has higher strength, with close to 700m of pure nickel wire placed inside the dummy from the fingers to the nasal cavity, and independent intelligent circuitry to ensure the accuracy of the measurement process. The internal circuitry in each part ensures the accuracy of the measurement and the built-in heat conduction system ensures a good uniformity. At the same time the dummy can be divided into two parts, easy to transport.
　　
The warm body dummy system device is used in:
Building thermal ventilation and air conditioning, comfort in airplanes and cars, thermal resistance testing of various types of clothing, research on wet suits and sportswear, analysis of the effects of cold and warm rooms on the human body, in high and low temperature environments, such as special fire experimental environments.
1. Building thermal ventilation and air conditioning.

The main characteristics of the warm dummy:
1. warm body dummy of the human body model is divided into head, torso, limbs and other anatomical segments of a total of 17 segments, each segment has adiabatic and fine-tuned heater in each segment, constant power control can do surface heating, constant temperature control.
2. In the control software section, the internal heat of the mannequin, the temperature insulation performance of the clothing, and the surface temperature evaluation of the mannequin, heat dissipation heat value calculation, etc., can handle various measurement data and records and statistical processing.
3. The mannequin of the warm body dummy is made with a resin with small heat capacity, which can quickly process the thermal reaction and heat exchange process of the mannequin.
4. Heat-sensing nickel wire sensors, connected to the whole system, can measure the average temperature in each segment with good sensitivity.
5. joints, shoulders and knees can be bent and changed to standing or sitting position, easy to remove clothing.
6. The warm body dummy system comes standard with a lifting frame for the mannequin, which allows easy movement of the mannequin.
