Warm dummy for environmental thermal comfort experiment

Abstract

The invention provides a warm dummy for an environment thermal comfort experiment. The warm dummy is characterized in that 16 electric heating sheets which are reasonably designed and can be produced in batches are adopted, so that compared with a traditional method that heating wires are directly wound on a dummy model manually, the manufacturing efficiency is greatly improved, and the cost is saved; the thickness, width and spacing of the electric heating wire of the heating sheet are uniformly designed according to the heat flux density requirements of each part, and the heating sheet is processed and generated at one time by adopting a copper sheet chemical etching method, so that the problem that the manufacturing precision is difficult to comprehensively guarantee in a traditional manual heating wire laying mode can be avoided; each heating sheet is obtained by utilizing a model curved surface unfolding method, and by virtue of a double-sided heat-conducting adhesive film, the good fitting property of the heating sheets and the surface of the dummy is ensured; the electric heating wire of the heating sheet adopts a corrugated design, so that the heating sheet has certain ductility; the input voltage of the electric heating wire is 24V and is within the safe voltage range of a human body; and the heating sheet adopts a three-layer film type structure.

Description

Technical field [0001] The present invention relates to a warm body fake person for ambient thermal comfort experiment. Background technique [0002] Whether it is aircraft, automotive, ship, etc., or carrier, submarine and other scientific research or military transportation tools, the internal thermal environment is an important factor affecting members' survival. In order to ensure that the occupants can effectively implement the assigned tasks in the transportation activities, it is first to ensure that the transportation tool can provide a suitable artificial environment (air ingredient, temperature, pressure, humidity, etc.). Therefore, the above-mentioned artificial environment is necessary to carry out the necessary environmental tests before investing in normal use, and the thermal environmental test needs to be used to replace the real human thermal load simulation. [0003] In the prior art, the warm body fake people typically use a method of winding the heating wire t...

AI Technical Summary

Problems solved by technology

Among them, the process of winding the heating wire needs to be manually operated, the production process is complicated and time-consuming, and the uniformity and surface fit of the heating wire are heavily dependent on manual operation experience, and the labor cost of the production process is extremely high.

[0004] At present, thermal dummies on the market mainly include products from three suppliers in the United States, Germany, and Hong Kong, China. The single price is around one million yuan, and the cost is high. Cabin environment thermal comfort test experiment
