Warm body sweating dummy

Warm body sweating dummy

This dummy can test detailed data systems, and the dummy itself does not have fingers or face. The dummy has higher strength, with nearly 700m of pure nickel wire placed from the fingers to the nasal cavity inside the dummy. The independent intelligent circuit ensures the accuracy of the measurement process. The internal circuits in each section ensure measurement accuracy, and the built-in thermal conductivity system ensures good uniformity. At the same time, the dummy can be divided into two parts, making it easy to transport.

Product Description:

In addition to dissipating heat 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 skin. If water vapor can spread to the surrounding environment through the clothing system in a timely manner, people will feel comfortable. If clothing obstructs the passage of water vapor, causing an increase in humidity in the microclimate between the human skin and clothing, water vapor will accumulate to a certain extent and condense into water, making people feel uncomfortable. When the human body engages in intense activities or is in a hot environment, the evaporation of sweat becomes an important way for the body to dissipate heat, which requires clothing to have sufficient water vapor transmission capacity. It can be seen from this 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 warm dummy system device is applied to:

Building thermal ventilation and air conditioning, comfort in aircraft and vehicles, thermal resistance testing of various clothing, research on wet and sports clothing, analysis of the impact of cold and warm rooms on the human body, high and low temperature environments, such as special fire experimental environments.

1. Building thermal ventilation and air conditioning.

2. Evaluation of aircraft and cars.

3. Thermal resistance testing of various types of clothing.

4. Research on wet clothing and sportswear.

5. Analysis of the impact of cold and warm rooms on the human body.

6. In high and low temperature environments, such as special fire experimental environments.

The main characteristics of the warm body dummy are:

The human body model of a warm body dummy is divided into 17 anatomical segments, including the head, torso, and limbs. Each segment has insulated and fine tuned heaters in each segment, and constant power control can achieve surface heating and constant temperature control.

In the control software section, various measurement data and records can be processed and statistically processed, including the internal heat of the human body model, the temperature insulation performance of the clothing, and the surface temperature evaluation and heat dissipation value calculation of the human body model.

3. When making the human body model of a warm mannequin, resin with small heat capacity is used, which can quickly handle the thermal response and heat exchange process of the human body model.

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

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

6. The warm body dummy system comes standard with a lifting bracket for the human body model, which can easily move the human body model.
