Expensive and bad, but don’t want to have a wet back, is the seat ventilation worth it?

When I didn’t buy a car, I was thinking how cool it would be to have a car with the air conditioner running in the summer. After I bought the car, I realized that the car after exposure to the sun is not as good as walking. I often get in the car and turn on the air conditioner to the maximum, and the seat cushion is so hot. Sitting on the stove, no matter the long distance or the short distance, the common point is that you will definitely like to lift a wet back.

During this process, the chassis, power, and handling of the vehicle have all become clouds. I just want to make the body dry and comfortable. The seat ventilation once became the TOP1 position in my wish list. You can see the price and parts of the options. After riders reported the seat ventilation failure, I wondered if I needed to endure the summer heat.

Taking the medium-sized car in the BBA as an example, the optional price of Mercedes-Benz C seat ventilation needs 9800 yuan, and the optional price of Audi A4 needs 9900 yuan. And invariably, in the top models with a price of nearly 400,000 cars, seat ventilation is required to be optional. Does it really need to be so expensive to ventilate the seats?

By the way, the reason for the absence of the BMW 3 Series is that it is not optional.

The Toyota Camry only comes with seat ventilation as standard on top-of-the-line models with both powertrains.

Seat ventilation takes almost as much effort as seat remodeling

It seems that seat ventilation only needs to arrange air ducts, fans and perforated seats, but there will be certain requirements for the material and overall structure of the seats.

The principle of seat ventilation is to leave ventilation holes in the foam layer of the seat and add a fan. The working principle is to use the fan to inhale the air and then introduce it into the ventilation layer. The airflow passes through the surface of the ventilation layer and passes through the perforated seat to dissipate heat.

In this picture, it can also be seen that the seat heating device and the seat ventilation device are compared, which seems to exist like a stealth. In fact, seat heating is as simple as it looks. The combination of electric heating wire and temperature sensor is almost the seat heating assembly, which is why there must be heating if there is ventilation, because heating is too simple.

First of all, the breathability of the seat skin material is the first test. The choice of this material is not as simple as we usually buy goods.

Secondly, after changing the structure of the seat, it is necessary to test the strength and durability of the seat. The foamed area mentioned above will even be replaced with materials to resist the change of support caused by the change of structure.

These tests include, but are not limited to, entry and exit simulations, simulated knee tests, driving simulation experiments, performance tests, etc. The energy expended is almost equivalent to remodeling a set of seats, and it is necessary to make every effort to make the seats last for more than ten years or even a few years. In good condition over a ten-year life cycle.

In addition to the above basic tests, the working noise of the fan is also a major problem that needs to be solved. It is necessary to balance the rapid cooling and noise caused by the vigorous rotation of the fan. It is better to have both. The best effect is The cooling is fast and quiet.

The fan needs to rely on the air volume to control the cooling rate. Since you want to be quiet and cool quickly, it is better to lower the intake air temperature, so we will see that some car companies with BBA as the main member will add additional air-conditioning vents , so that the cooling efficiency is greatly improved.

Seat ventilation is indeed complicated, and I understand the increase in cost, but my throbbing heart still hopes to find a product that "replaces" seat ventilation.

After several purchases, I personally think that the linen seat with the pattern in the picture is the most refreshing and comfortable.

At the same time, the disadvantages are also obvious. First of all, the price is significantly higher than that of conventional seat cushions. Secondly, the height of some seat cushions will be increased in response to the refreshment it brings. This is difficult for vehicles with limited head space. "curb quality".

Summarize

Although seat ventilation will have more complicated manufacturing procedures, the threshold for standard seat ventilation for some new power brands and domestic brands is also getting lower and lower.

At the current stage when there are no insurmountable barriers to driving quality and power, consumers are more inclined to choose a partner who will make them more comfortable to accompany them. The configuration of seat ventilation is obviously not a reason to buy a car, but car companies The final result of "involution" between them will not be too bad, and it is also gradually moving away from the ethos of distinguishing consumers by configuration.
