Male thermal manikin

Product Description:

In addition to heat dissipation to the surrounding environment through conduction, convection, and radiation, the human body also loses heat through the evaporation of sweat on the surface of the human skin. If water vapor can diffuse through the clothing system to the surrounding environment in time, people will feel comfortable. If clothing obstructs the passage of water vapor and increases the humidity in the microclimate between human skin and clothing, the water vapor will accumulate to a certain extent and condense. It becomes water and makes people feel uncomfortable. When the human body is engaged in vigorous activities or is in a hot environment, the evaporation of sweat becomes an important way for the human body to lose heat. At this time, clothes are required to have sufficient water vapor transmission capacity. It can be seen that it is necessary to accurately test the evaporation resistance of clothing in order to make a comprehensive evaluation of the heat and moisture transfer performance of clothing.
 
The dummy can test detailed data systems, and the dummy itself does not have fingers and faces. The dummy has a higher strength. A pure nickel wire close to 700m is placed from the fingers to the nasal cavity inside the dummy. The independent intelligent circuit ensures the accuracy of the measurement process. The only circuit inside each part ensures the accuracy of the measurement, and the built-in heat conduction system can ensure good uniformity. At the same time, the dummy can be divided into two parts, which is easy to transport.
　　
The thermal manikin system device is used in:

Building thermal ventilation and air-conditioning, the comfort of airplanes and cars, the thermal resistance test of all kinds of clothing, the research of wet clothes and sportswear, the analysis of the impact of heating and cooling rooms on the human body, the high and low temperature environment, such as the special fire experiment environment.

The main features of the thermal manikin:

1. The whole body of the mannequin is divided into 17 anatomical sections such as head, torso, and limbs. Each section has adiabatic and fine-tuned heaters in each section. Constant power control can achieve surface heating and constant temperature control.

2. In the control software, the internal heat of the human body model, the temperature insulation performance of the clothing, and the surface temperature evaluation of the human body model, heat dissipation calorific value calculation, etc., can process various measurement data, records and statistical processing.

3. The resin with small heat capacity is used to make the human body model of the warm body manikin, which can quickly handle the thermal reaction and heat exchange process of the human body model.

4. Thermal nickel wire sensor, connected to the entire system, can measure the average temperature in each section with good sensitivity.

5. The joints, shoulders and knees can be bent and can be changed into a standing or sitting position, making it easy to remove clothes.

6. The body warmer system is equipped with a mannequin lifting frame as standard, which can easily move the mannequin.
