Although it has begun to fall, but there is still a fall tiger, the car is still under the hot sun to receive roasted and exposed. As the interior of the car is a confined space, the internal temperature can reach 40-50 degrees minutes and minutes, and it can fry eggs and burn teppanyaki. Just imagine what happens when such a high temperature person gets in? It certainly won't be good. Is there any way to effectively reduce the interior temperature before driving? Then let's take a look at some of the ways which are faster and more effective.
1, artificial cooling
Artificial cooling is to manually switch the door 5 times. It is reported that this method is a rapid cooling method experimentally validated by Prof. Sakai Hiroyuki of Japan. The method is to first open the front passenger seat window, and then switch the driver's seat door 5 times. Using the power of the sliding door, the hot air is discharged from the side of the door, and the outside cold air can come in through the window of the front passenger seat, thus achieving the effect of temperature drop. However, this method has a BUG, ​​that is, the hot days of their own in the car door made the car cool, but made it sweat.
2, alcohol cooling
Alcohol cooling is the use of alcohol which is volatile and can take away heat when volatilized. The method is to first adjust the alcohol concentration. The ratio of alcohol and water is adjusted to 1:10, and then the spraying tool is used to spray around the vehicle. After a minute of spraying, the temperature inside the car will be significantly reduced. What we have to say here is that although alcohol is also flammable, in fact, as long as the ratio of alcohol and water is properly prepared, there is basically no risk of burning, so you can rest assured. This method has low cost and obvious effect.
3, cooling agent cooling
The cooling agent is a preparation that can quickly reduce the temperature inside the car. The main ingredients are dry ice, softened water, and a small amount of spices. The method is to open the door and spray the cooling agent on the surface of the vehicle, the seat, and the vehicle disc without starting the vehicle and the air conditioning in the vehicle. When the cooling agent is heated, it quickly vaporizes to absorb the heat on its surface. After using the cooling agent for 1 minute, the temperature in the vehicle can drop by 20°C. Therefore, the cooling effect of cooling agent is still very good, a bottle of cooling agent can be used about 3 to 5 times, and a bottle of about 10 yuan, compared to the cost of the first two are higher.
In fact, there are many ways to cool down, and the best effect is definitely to park in the indoor parking lot. Of course, it is hard to find a car parked outside, not to mention the parking lot. In this case, the above cooling method is relatively simple and practical, and the operation is simple. We might as well try.
Steel frame electric bicycles, processing performance, chromium-molybdenum steel is the oldest bicycle materials, the longest of its research, the processing technology has been developed to a very stable level. 2. Strength According to the conclusion of the car, it can be concluded that car enthusiasts can draw the conclusion that the strength of the same volume steel is much larger than that of aluminum alloy and titanium alloy, so the strength of qualified steel frame can be reassuring. 3. Take a comfortable, good steel elastic steel made of metal, can absorb the vibration when riding. Therefore, the steel frame will not be as uncomfortable as the aluminum frame, especially for the travel frame. 4. Steel metal fatigue stronger than aluminum, so the same conditions of use, the life of the aluminum frame longer life. Of course, the steel frame also has its insurmountable shortcomings: 1. Light weight, today in the pursuit of lightweight equipment, the quality of 7.8g / cm3 steel so that everyone does not encourage him. Although light steel construction, while pumping pumping technology wall is very thin, but the weight of the steel is difficult to reduce to 1600 grams or less. Many aluminum frame weighs only about 1400 grams. This is a competitive framework, rarely seen the reasons for the steel frame. 2. Rusted, relative to other materials, steel is relatively easy to rust. Rust can drastically reduce the strength of the steel, shortening its service life. (Such as BEARS these frames in order to prevent the problem of rust to the framework of the new tube coating), so we must take various measures to prevent rust.
