Abstract
The utility model relates to a PTC electric heater for an electric vehicle, which is used for a vehicle air conditioning system. The PTC electric heater for the electric vehicle comprises a square-shaped frame corresponding to an air outlet of the vehicle air conditioning system, wherein a plurality of aluminum heat sink strips are abreast arranged in the frame, and a plurality of PTC electric heating tubes with flat casings are clamped among the aluminum heat sink strips. The PTC electric heater for the electric vehicle has the advantages that 1 the heat sink strips arranged compactly and the PTC electric heating tubes can obtain larger heating power in a narrow space of a vehicle; 2 the heating sink strips are tightly fixedly connected with the PTC heating tubes through braze welding, so that the integral strength of the electric heater is increased, and the electric heater can be adaptable to bumpy and vibrated operation environments of the vehicle; and 3 on the basis of self-protection to over heating, the PTC electric heater can monitor operation temperature at real time so that operation reliability of electric heating is further improved through a traffic computer system.
Description
Technical field
The utility model relates to a kind of electric automobile PTC (Positive Temperature Coefficient) electric heater that is used for automotive air-conditioning system.
Background technology
In fuel-engined vehicle, the interior heating of automobile in winter is to adopt independent thermal source formula (fuel oil) heating system or waste heat formula (utilizing engine cooling water or waste gas residual heat) heating system.These two kinds of automobile heating service systems all need to depend on the engine of automobile, that is to say could to implement the heating in the automobile under the state of engine operation, in case engine stop work heating does not just realize yet.In addition, the heating efficient of this heating system is very low, and its structure is more complicated also, has started in the time of in the winter time that need behind the engine could heat supply after 6-10 minute.Owing to requirement energy-conservation and that reduce discharging, electric automobile becomes the developing direction of automotive engineering in recent years.And the heating of warming oneself in electric automobile also is the problem of car manufactures common concern and research, and existing common electrical heater is difficult to directly apply in the electric vehicle air conditioning system.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of operational environment of suitable electric automobile, simple in structure, programming rate is fast, functional reliability is high electric automobile PTC (Positive Temperature Coefficient) electric heater are provided.
Electric automobile PTC (Positive Temperature Coefficient) electric heater of the present utility model includes the framework of a square shape that adapts with the automotive air-conditioning system air outlet, a plurality of aluminium heat sink strips that are arranged side by side in framework, a plurality of PTC electric heating tubes with flat shell are clamped between each aluminium heat sink strip.
Described aluminium heat sink strip is made of undulatory fin, and undulatory fin is connected and fixed with the housing of brazing mode and PTC electric heating tube.
But also be provided with the fuse of the thermal protector that can recover automatically that is connected in the electric heater current supply circuit and overheat fusion on the described framework.
Also be provided with the temperature sensor that is connected in the automobile air conditioner control system on the described framework.
The utility model has the advantages that: 1, the heat sink strip of intensive setting and PTC electric heating tube can obtain bigger heating power in the narrow space of vehicle, can satisfy the instructions for use of automotive air-conditioning system; 2, heat sink strip is closely fixedlyed connected by soldering with the PTC electric heating tube, has improved its bulk strength, can adapt to the running environment that vehicle jolts and vibrates; 3, on the basis of the overheated self-protection that can realize electric heater unit by thermal protector and fuse; can also monitor in real time operating temperature by the temperature sensor that is connected with the vehicle air conditioning control system, thereby can utilize the car running computer system further to improve electrically heated operational reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, this electric automobile PTC (Positive Temperature Coefficient) electric heater includes the framework 1 of a square shape that adapts with the automotive air-conditioning system air outlet, a plurality of aluminium heat sink strips 2 that are arranged side by side in framework, a plurality of PTC electric heating tubes 3 with flat shell are clamped between each aluminium heat sink strip 2.Aluminium heat sink strip 2 is made of undulatory fin, and undulatory fin is connected and fixed with the housing of brazing mode and PTC electric heating tube 3.But framework 1 is provided with 139 ℃ of fuses 5 of the 85 ℃ of thermal protectors that can recover automatically that are connected in the electric heater current supply circuit 4 and overheat fusion.Also be provided with the temperature sensor 6 that is connected in the automobile air conditioner control system on the framework.
