Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
In order to further illustrate particular content of the invention elaborates with reference to the accompanying drawing:
Referring to Fig. 1, a kind of air conditioning for automobiles HVAC Air System, the changes in temperature air door 2 being mounted on the total shell 1 of air-conditioning box,
Multiple air outlet 1-1 on empty van shell are set；Since air-conditioning box assembly is located on the inside of panel assembly, peripheral product compared with
More, so sized boundary often has certain limitations, and the size of heat exchanger is directly proportional to its heat exchange property.To meet vehicle simultaneously
Space layout and heat exchange property requirement, it may appear that heat exchanger is comfortable to reach the case where shell interior biasing is in left and right wind outlet
Temperature Distribution, on changes in temperature air door towards air outlet side be equipped with asymmetric wind-guiding gusset 3, and the wind-guiding gusset from
Changes in temperature air door windward side is tilted towards shaft centerline direction；Increase asymmetric water conservancy diversion gusset on changes in temperature air door to do air
Certain guiding role changes air flow direction；This method can be before meeting vehicle assembly space and not reducing heat exchange property
It puts and realizes Temperature Distribution demand.
Above structure, it is preferred that the guiding gusset and changes in temperature air door integrated injection molding.
Above structure, it is preferred that the tilt angle of the wind-guiding gusset is 20~25 °.
Above structure, it is preferred that the length of the wind-guiding gusset is 105~112mm, the height of the wind deflector is 12~
18mm。
Existing air-conditioning box assembly product using when there are changes in temperature to mix wind mode, on automatic air condition mix wind mode using more frequency
It is numerous.But many times cold air cannot be thoroughly mixed, and have layering in temperature, and causing the leaving air temp from each air outlet to have cold has
Warm, non-uniform temperature reduces vehicle comfort.To solve this problem, increase by one is independent inside air-conditioning box assembly
