A warm body dummy for environmental thermal comfort experiment

Abstract

The invention provides a body-warming dummy for environmental thermal comfort experiment, which adopts 16 electric heating sheets which are reasonably designed and can be mass-produced, and the traditional method of directly winding heating wires on the dummy model by hand. Compared with the heat flux, the production 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 flow density requirements of each part, and are produced by one-time processing by the chemical etching method of the copper sheet, which can avoid the traditional It is difficult to fully guarantee the production accuracy by laying the heating wire manually; each heating piece is obtained by the method of unfolding the surface of the model, and the double-sided thermally conductive adhesive film is used to ensure the good fit between the heating piece and the surface of the dummy; the electric heating of the heating piece The wire adopts a corrugated design, which makes the heating piece have a certain ductility; the input voltage of the electric heating wire is 24V, which is within the safe voltage range of the human body; the heating piece adopts a three-layer film structure.

Description

technical field [0001] The invention relates to a body-warming dummy for environmental thermal comfort experiment. Background technique [0002] Whether it is commercial vehicles such as airplanes, cars, ships, or scientific research or military transportation vehicles such as manned spacecraft and submarines, the internal thermal environment is an important factor affecting the survival of members. In order to ensure that the occupants can effectively perform the assigned tasks during the transportation activities, it is first necessary to ensure that the transportation means can provide a suitable artificial environment (air composition, temperature, pressure, humidity, etc.) for the occupants in the aircraft. Therefore, the above-mentioned artificial environment must undergo necessary environmental tests before being put into normal use, and in the thermal environment test, it is necessary to use a warm-up dummy instead of a real person to simulate the thermal load of the...

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
