Of course, car owners can also choose to use sunshade gears. The most important thing is to block out the sun so that the sun cannot enter the car. To a certain extent, it reduces the combustion effect of the car and avoids the effect that the leather seat and dashboard are damaged by ultraviolet light.
The first choice to block the sun, of course, is the sunshade, but it has a certain impact on the line of sight. The second is to propose explosion-proof film and solar film. The most practical thing is to buy a polarizer for the driver. But with polarizer to remember one, suddenly enter the tunnel or parking lot and other dark areas should pay attention to safety.
Of course, if you buy some of the more expensive models, then the meters in your car are likely to come from high-end watch manufacturers, such as Jaeger and Wanguo. For example, the Mercedes-Benz 680s dashboard in 1928 is dotted with more than a dozen circular pointer dashboards, which can be mistaken for the built-in display cabinets of a watch shop. Moreover, even if it comes from a famous family, it can not solve the problem that the instrument is not easy to read due to the reflection on the surface of the instrument and the lack of radians on the instrument as a whole, which gives birth to the emergence of sunken instruments and instrument sunshades.
Car sunshade when the sun is empty, love the car can not always park in the shade or underground parking lot summer bar, more often have to rely on the sunshade to solve the problem. Each car is equipped with sunshades, installed above the heads of drivers and co-drivers, which can be called an “artifact” to ward off the dazzling sun while driving. However, with eggs, you will find two sunshades at a critical time, park your car in the hot sun for a moment, change into a sauna in a second, and the temperature will soar. So someone invented a better product-car sunshade, which is mainly used to block the front and rear windshield and four windows. The sunshade is made of reflective aluminum foil coil material, which can play a better heat insulation and shading effect, and it is also very convenient to be collected and used. In addition, in addition to ordinary aluminum foil coiled sunshades, there are more personalized sunshades to choose from, including a variety of patterns and customized models for special models.
Why the car stereo can not be exposed to the sun, the car audio is mostly installed on the upper part of the dashboard; if the door and window seals are not strict, they should be replaced, otherwise the loudspeakers are easy to rust and damage, or even cause short-circuit burning of the mainframe; the circuit boards and plastic components in the audio mainframe have different degrees of aging due to temperature changes. In the scorching sun, it is good to use sunshades to ward off the scorching sun and avoid direct sunlight.
As can be seen from the above picture, through horizontal shading, a certain direct area can be reduced on the outer window, which makes the radiation heat to the building caused by the heat of the outer window (red wave arrow part). At the same time, through the upper reflective surface of the sunshade, the sunlight is reflected to the ceiling of the building, and then through the diffuse reflection of the ceiling, the daylighting inside the building is increased (orange wave arrow part). It should be noted that this part of the reflected light also brings part of the energy into the room, which will cause indoor load, but the heat of reflected radiation can be reduced by using selective reflection coating, therefore, the heat caused by this part of solar reflected radiation can be considered to be much less than that caused by direct sunlight.
Car sunshade can prevent leather seats and dashboards from being damaged by ultraviolet rays. Direct exposure to the sun will make the temperature in the car as high as 70 degrees. Not only the shell of the central console is easy to deform, instruments and other equipment on the dashboard are also damaged by high temperature, such as aging components, pin soldering, etc., sunshade can effectively avoid direct sunlight.
