What kind of seat heating pads do you have?

There are two heating methods for automobile seat heating pad: built-in automobile heating pad and external automobile heating pad.

The working principle of seat heating is relatively simple. The seat is covered with a resistance heating wire, which is sewn in the seat cover, and is heated by energizing the heating resistance wire, so that the temperature of the seat is gradually increased in a short time; By setting a temperature sensor in the heating pad, the change of seat temperature can be monitored.

So as to control the power on and off of the heating wire and keep the heating temperature of the seat within a proper range. It is not difficult to see that the working principle of seat heating is very similar to that of electric blanket. Because the heating wire itself is soft, it will not occupy too much space in the seat, so there is no need to change the internal structure of the seat, and the cost is naturally not too high.

Seat heating instructions are as follows:

Compared with the internal structure of seat heating, seat ventilation is much more complicated. It is necessary to add ventilation systems to the seat cushion and backrest respectively, and use fans to suck air into the ventilation layer. After punching holes in the seat surface, the airflow can penetrate the ventilation layer upwards and blow to the seat surface.

In order to leave the position of the fan, the internal structure of the seat needs to be changed, and the noise and vibration of the fan, ventilation and cooling speed are also factors to be considered. The foam and covering of ventilated seats also need special structure to meet the ventilation needs. The complicated structure and low cost should be the biggest reason why the ventilation permeability of the seat is lower than that of the seat heating.

Phoenix net-seat heating is very common, why is the seat ventilation penetration rate so low? The reason is very
