Fig. 1 is an oil-water separation heater schematic top plan view;
Wherein: 1, Thermal Cutoffs, 2, heating pipe, 3, temperature controller, 4, the diesel oil heating cup, 5, heated base, 6, the dewatering outlet.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
Shown in Figure 1, the oil-water separation heater, its structure comprises, diesel oil heating cup 4, heating pipe 2, diesel oil heating cup 4 is a cylindrical cavity, heating pipe 2 is the airtight heating pipe of circular insulation.
The oil-water separation heater is the self-temperature-control type heater.Its distinguishing feature is that heat transfer is fast, the thermal efficiency is high.Diesel oil heating cup 4 is combined closely by the cleaner bottom secction of worm structure and seal ring and diesel engine, heated base 5 is by the firm bottom that is installed in diesel oil heating cup 4 of tapping screw, and by the close-fitting through hole in bottom lead is drawn, be attached on the vehicle-mounted 24V power supply of motor car engine.When diesel stream is crossed filter cleaner, liquid is full of whole diesel oil heating cup 4.If diesel fuel temperature is lower than the setting temperature of temperature controller 3, temperature controller 3 automatic conductings, heating pipe 2 begins heating, the temperature of diesel oil is improved constantly, mobile constantly increase, when the oil temperature reached the break-off signal that temperature controller sets, temperature controller 3 cut off the power supply automatically, and heating pipe 2 stops to heat.If temperature controller 3 can't stop heating because accidental cause lost efficacy, can not make diesel fuel temperature overheated and finally cause fire to take place yet, this mainly is because the present invention all has the double insurance function.Under the situation that temperature controller 3 lost efficacy, temperature will be by Thermal Cutoffs 1 control.Between 3 controlling temperatures of Thermal Cutoffs 1 and temperature controller certain temperature difference is arranged, when temperature controller 3 inefficacies, when the oil temperature reaches Thermal Cutoffs 1 setting temperature above temperature controller 3 setting temperatures, Thermal Cutoffs 1 fusing, circuit is disconnected by force, guarantee engine health.Its compact overall structure, volume is little, and cost is low, and is flexible for installation, and temperature controller is easy to type selecting.
The utility model is applied widely, can heat different medium.
