Problems solved by technology

[0004] In terms of the automobile industry, the solar radiation simulator currently used in China mainly uses halogen lamps and infrared lamps as light sources, and its spectrum has a certain deviation compared with natural light. The thermal effect is mainly used to evaluate the performance of the vehicle air conditioner, without considering the actual energy absorbed by the surface of the experimental vehicle under natural light conditions, so it is quite different from the changes in the cabin microenvironment caused by natural light
The controllable range of sunlight energy density simulated by halogen lamp is 600~1000W/m 2 , can not cover my country's 200 ~ 1200W/m 2 range of natural light
And most of the simulators are only designed to illuminate the top of the car body, failing to take into account the thermal effect caused by direct sunlight on the side wall

Description

technical field [0001] The invention relates to the technical field of the correlation between the thermal effect of a vehicle cabin and sunlight and the control of the cabin micro-environment, in particular to a matrix solar radiation simulation experiment system for vehicle thermal comfort research. Background technique [0002] In summer, when the vehicle is exposed to the sun, the car body will absorb the energy of the sun's rays, resulting in high temperature in the cabin, and the cabin microenvironment is relatively harsh. The high temperature in the cabin directly affects the physiological condition and work efficiency of the operators, leading to a decrease in ride comfort and even causing traffic accidents. Reports of sudden death of drivers and children being mistakenly locked in cars due to high temperature inside the car every year are not uncommon. For military combat vehicles, the temperature rise caused by solar radiation will also increase the probability of...
