When a car is parked under the direct sun,the accumulated heat causes the car cabin and interior temperature to increase rapidly.When it's hot outside the temperature inside a car cabin can reach dangerous and sometimes fatal levels in a matter of minutes.Also,it represents an uncomfortable operating period for the passengers.This paper presents the experimental results of an innovative device for the temperature restriction in the interior compartment of a stationary car facing the solar energy from the sun.A very light restricted temperature device placed in the ceiling of the car through which the heat is removed with convective ventilation powered by solar energy.As a result the temperature of the car cabin is maintained in the comfort condition.This new device can be easily implemented as a practical solution to prevent undesirable heating in car cabins.The restricted temperature device is simple and has a potential to be implemented as a practical solution to prevent undesirable heating of the car's cabin.According to the quantitative data,the maximal temperature reduction at the driver's seat can reach 5.7 ℃ in 259 seconds with a relative reduction of 12.5%.
