Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, the most ad initio
Represent same or similar element to same or similar label eventually or there is the element of same or like function.Below by ginseng
It is exemplary for examining the embodiment that accompanying drawing describes, it is intended to be used for explaining this utility model, and it is not intended that to this utility model
Restriction.
As in figure 2 it is shown, the heating assembly of the heater of the existing air conditioning system for electric automobile is along described
The horizontal direction of the air outlet of air conditioning system is arranged.It is obvious that based on this structure, regulation controls end 2 and control end 3 can only be adjusted
Save the total amount of heat of described air conditioning system air outlet.Specifically, ptc heater the total amount of heat produced is in the level side of air outlet
Distribution upwards is uniform, and the distribution on the vertical direction of air outlet is adjustable.For example, end 2 is controlled when Guan Bi
Time, heater strip A, C, E work as heating source；When Guan Bi controls end 3, heater strip B, D, F work as heating source；When simultaneously
When Guan Bi controls end 2 and controls end 3, heater strip A, B, C, D, E, F work simultaneously as heating source.
Under the structure of the ptc heater of existing air conditioning system is arranged, it is desirable to meet different temperatures output, can only pass through
Arrange air door to regulate.But, the heat regulation effect of this structure is not fully up to expectations, it is impossible to meet the use that user strengthens day by day
Family is experienced.
Below with reference to the accompanying drawings 3 describe in detail according to this utility model embodiment for electric automobile air-conditioning system
PTC heater.As shown in Figure 3, according to the PTC heater 100 for electric automobile air-conditioning system of the present utility model
