The structure of a traditional air door and a traditional baffle is shown in the attached drawing 1, and cold air and hot air are exhausted after passing through an air door body and the baffle.

The defects in the prior art are as follows: the air flowing through the cold runner and the air flowing through the hot runner are not mixed uniformly, the temperature difference gradient of the air opening is large, and the comfort degree of the air opening is poor due to sudden cooling and sudden heating.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an air door structure that wind gap difference in temperature is optimized to solve the wind gap and neglect cold suddenly hot, the poor problem of comfort level in the car.

In order to achieve the purpose, the utility model provides an air door structure that wind gap difference in temperature is optimized, including the air door body, the air door body rotates to be connected in the runner of ventilation casing, be equipped with the vent on the air door body, the air door body is equipped with the baffle, the baffle is followed the air door body is rotatory, its characterized in that: the baffle is the form of buckling, be equipped with unevenness's structure on the baffle.

For effectual vortex, improve the homogeneity that cold wind and hot-blast mix, rugged structure is the sawtooth on the baffle.

Preferably, the ratio of the wave distance to the wave height of the saw teeth is 2:1.

in order to enlarge the turbulent flow range, the two baffles are symmetrically arranged on the left and right of the air door body.

In order to directionally control the wind direction and collect the wind, the left end and the right end of the baffle are bent in the same direction, so that the cold wind and the hot wind are collected towards the middle to be convenient for mixing.

Preferably, the baffle is located right in front of the ventilation opening, and the baffle is perpendicular to the damper body.

In order to reduce the manufacturing cost, the baffle is integrally formed with the damper body.

The utility model has the advantages that: cold air and hot air can generate turbulent flow with different degrees when passing through the rugged structure, compared with a straight plate baffle, the air port has high mixing uniformity degree and small temperature difference change, as figure 3 is turned angle and temperature curve graph, the abscissa is turned angle, the ordinate is the front row difference in temperature, through with the contrast experiment of straight board baffle experimental condition: inlet side air temperature-15 ℃; the water inlet temperature is as follows: (85 +/-2) DEG C; water flow rate: 6L/min; test medium: 50% water +50% ethylene glycol; installing an actual vehicle air pipe, an air outlet, a filter screen and the like; mode (2): blowing the face, blowing the feet to defrost and defrost, wherein the scheme of the straight plate is an A curve, the front row temperature difference adopting the straight plate scheme has large gradient change, the rotation angle and the temperature curve are parabolic, and the temperature is greatly changed by the rotation angle; the scheme is a curve B, the up-and-down fluctuation of the rotation angle and the temperature curve is small, the front row temperature difference change is small by adopting a sawtooth scheme, the hot air and the cold air are uniformly mixed, the temperature difference fluctuation range of the air port is small, and the comfort level in the vehicle is effectively guaranteed; the whole structure is simple, and the production cost is low.
