Abstract
The utility model relates to an air inlet heater of a diesel engine, comprising a PTC electric heating element, a machine shell, an electric heating board, etc. The PTC electric heating element is a heating body, and the external side of the electric heating element is bonded with the electric heating board; a heat sink is rivet-welded at both sides of the electric heating board. When the power source is switched on, the heater can heat in constant temperature rapidly and the air can get in, so as to meet the required air inlet temperature of the cold start of the diesel engine. The utility model is suitable for the vehicles provided with the diesel engine, such as a diesel car, a tractor, a ship, etc.
Description
The utility model relates to a kind of diesel engine intake heating equipment, belongs to the diesel engine cold start technical field.
Aspect prior art, air inlet heating devices such as some diesel engine using plug type electric heating, type of furnace electric heating, flame air inlet.It is heater that the electric heating air inlet heating device adopts nickel chromium triangle electric heating bandlet, and the temperature rise time surpasses 45 seconds, because of overheated easy fusing; The flame air inlet heating device, flame is easily put out by cold airflow, and the blackening of heater plug root magnesia powder causes red-hot plug short circuit, and electric current increases, and damages controller.
The purpose of this utility model is: provide a kind of can the air inlet of quick temperature heated diesel, satisfy the heater of the intake temperature of diesel engine cold start needs.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described:
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model;
Wherein: 1.PTC electric heating element, 2. casing, 3. electric hot plate, 4. copper sheet, 5. radiating fin, 6. high temperature wire, 7. rivet
This pass will be by PTC heating (1), casing (2), electric hot plate with Novel main (3), the formations such as copper sheet (4), fin (5), high temperature wire (6). PTC electric heating unit Part (1) is heater, and copper sheet (4) is bonded in two groups of PTC electric heating units as positive electrode In the middle of the part (1), the outside of PCT heating (1) is respectively bonding with electric hot plate (3); Fin (5) rivet welding is in the both sides of electric hot plate (3). High temperature wire (6) copper sheet (4) phase Connect, pass through the wire hole of casing (2). By PTC electrothermal piece (1), copper sheet (4), Electric hot plate (3), fin (5) consist of the movement of this heating, by rivet (7) with this movement Be riveted on the casing (2).
Adopt this warmer of the PTC heating composition of modular in design, the work electricity Press: 24 volts; Resistance: 1 ohm; TC:300 ℃. The utility model is installed in diesel engine Air filter and air inlet pipe junction.
The utility model is after connecting power supply, and the fast constant temperature heating air inlet satisfies the needed intake temperature of diesel engine cold start.Have the long characteristics of quick high-temp, constant temperature, low, the anti-dry combustion method of power consumption, life-span, be applicable to the diesel engine assembling light, in, heavy-duty diesel vehicle, engineering truck, tractor, steamer etc.
Claims (1)
