Abstract
The utility model relates to a positive temperature coefficient (PTC) electric heater for an automobile air conditioner. Fin strips are evenly distributed in a rectangular frame of the electric heater and a heating bar is arranged between two adjacent fin strips and forms a whole with the fin strips in a brazing mode. A wire bundle is connected at one side of the rectangular frame. The heating bars are made of PTC heating pipes. Odd heating bars are connected in parallel to form a group and a gear and even heating bars are connected in parallel to form another group and another gear. The two groups are respectively connected with the wire bundle through wires. The fins are wave-shaped fins. A window is arranged in every half wave in an angle of 25 degrees. According to the PTC electric heater for the automobile air conditioner, heating is controlled by divided gears and a user can choose to start a gear or start all heating bars based on the air temperature. The radiating fins are wave-shaped fins and the radiating windows are arranged in the fins. Radiating efficiency is improved. A traditional water heating device or an auxiliary heating device can be replaced by the PTC electric heater for the automobile air conditioner.
Description
Technical field
The utility model belongs to the temperature booster technical field, is specifically related to the automobile temperature booster.
Background technology
New-energy automobile is an a new direction of development of automobile, and temperature booster is used as heating in winter and defrosting, and a part is absolutely necessary.In the new-energy automobile, directly with the energy source of electric energy as heating, convenient and reliable, cal val is high, and is controlled.In pure electric automobile, adopt the PTC electric heater, still, but had following improvements: 1, do not divide gear control, be arranged in heating strip or energising in the PTC, or outage, can not be according to the temperature height, by the different gear controls of user selection; 2, radiating fin is corrugated fin, does not window, and heat-sinking capability is to be improved.
The utility model content
Regulate for the heat-sinking capability of improving temperature booster, the stepping of realizing heating, it is a kind of from controlling upper improved used for automobile air conditioning PTC electric heater that the utility model provides.
The improved technical scheme of the utility model is as follows:
Used for automobile air conditioning PTC electric heater comprises rectangular frame 1, and interior uniform the fin 3 of rectangular frame 1 is provided with heating strip between the adjacent fins 3, and heating strip and fin 3 are connected to form an integral body by soldering; Rectangular frame 1 one sides are connecting wire harness 4, and improvement is: described heating strip is comprised of the PTC heat-generating pipe; The heating strip parallel connection of odd number is one group, forms one grade, and is connecting wire harness 4 by wire; The heating strip parallel connection of even numbers is another group, forms another shelves, and is connecting wire harness 4 by wire.
Described fin 3 is corrugated fin, has window at each half-wave, 25 ° of louver angles.
Useful technique effect of the present utility model embodies in the following areas:
1. PTC being carried out stepping control, for example, by the heating strip of odd number and even numbers is in parallel respectively, form two gears, is to open one grade or many grades by user selection;
2. radiating fin adopts corrugated fin, and opens thermal window at fin, has improved radiating efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
Sequence number among the upper figure: rectangular frame 1, heating strip 2, fin 3, wire harness 4.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Referring to Fig. 1 and Fig. 2, fin 3 and heating strip 2 are placed in the rectangular frame 1 interior interval of used for automobile air conditioning PTC electric heater, and they connect an integral body by soldering; The wire harness 4 of one side of rectangular frame 1 is connected connection with heating strip.Heating strip 2 forms for the PTC heat-generating pipe; Be stepping control, for example: the heating strip parallel connection of single sequence number is one group, forms one grade; The heating strip parallel connection of two sequence numbers is another group, forms another shelves 4.Fin 3 is corrugated fin, has window at each half-wave, and 25 ° of louver angles are seen Fig. 3.
Principle of work of the present utility model: heating after heating strip 2 energisings reaches the specified power substantially constant.The PTC heat-generating pipe is positive temperature coefficient resistor, and the conventional, electric-resistance different in kind, and temperature is high, and resistance is high; Temperature is low, and resistance is little, according to the formula of resistance energising consumed power: P=U
2/ R, after the heating strip temperature reached certain temperature, resistance value was stable, power with regard to basicly stable a value.The PTC flames of anger, safer.When the moving air of the car internal fan manufacturing fin 3 of flowing through, air is heated, thereby reaches the purpose of heating.The user can select to open one grade or many grades as required.
