The PTC heating assembly 3 is fixedly installed in the aluminum frame 2. The insulating outer frame 1 is coated on the outer side edge of the aluminum frame 2. The heat dissipation runner 23 is arranged in the aluminum frame 2, an air inlet 24 and an air outlet 25 which are respectively communicated with the heat dissipation runner 23 are arranged on one surface of the aluminum frame 2 facing the air inlet end of the PTC heating assembly 3, and the air inlet 24 and the air outlet 25 are respectively positioned on two sides of the PTC heating assembly 3.
The automobile air conditioner heater of the embodiment can be installed in an automobile air conditioner air duct, the structural strength of the PTC heating assembly 3 can be increased by the aluminum frame 2, and the structural stability of the PTC heating assembly 3 is maintained, so that the wind pressure resistance of the PTC heating assembly 3 is increased.
The aluminum frame 2 of the automobile air conditioner heater is internally provided with a heat dissipation flow channel 23, and an air inlet 24 is connected with an air flow conveying end, so that cold air firstly enters the heat dissipation flow channel 23 and then is discharged to the air inlet end of the PTC heating assembly 3 through an air outlet 25. When the cold air flow passes through the heat dissipation runner 23, heat dissipation can be carried out on the aluminum frame 2, so that the temperature of the aluminum frame 2 is always lower than the temperature of the surface of the PTC heating assembly 3, and the heat conducted by the aluminum frame 2 can be prevented from deforming the insulating frame due to heating.
On the other hand, because the cold air flow is preheated once when passing through the heat dissipation flow channel 23, the air flow passes through the PTC heating component 3 for heating after being preheated, the time of air flow heat exchange is increased, and the temperature difference between the air inlet end and the air outlet end of the PTC heating component 3 is reduced, so that the heating efficiency of the heater can be improved, and the service life of the heating component is prolonged.
