Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to figs. 1 to Fig. 3.Diesel oil preheating of the present utility model heater assembly comprises collecting bowl 1, is arranged on heating equipment 2 and drain valve 3 in the collecting bowl 1.
Collecting bowl 1 has the chamber 10 of an open-topped, and the wire harness that the bottom surface of chamber 10 is provided with a heating equipment passes hole 14.The outer circumferential face of collecting bowl 1 is provided with an annular groove 11, and 11 are embedded with seal ring 50 in this annular groove.
Above-mentioned external power supply comprises the ECU(or the ECM of motor) or car battery.When driver and passenger's opening automobile ignition switch, ECU(or ECM by motor) or car battery provides the input power supply to this heater assembly, under an assigned temperature condition, temperature detect switch (TDS) 42 conductings of heater assembly, ptc heater 41 beginning heating works.Because the own characteristic of ptc material, very low at the early stage PTC resistance of heating, at this moment, export a big current value, along with the rising of ptc heater temperature, the PTC self-resistance increases, the PTC electric current can reduce, thereby realized the self-regulating function of PTC heating, greatly reduced loss of power efficient, improved the product characteristics of energy saving.Continue at ptc heater under the condition of heating, the ambient temperature of temperature detect switch (TDS) 42 improves constantly, make temperature detect switch (TDS) 42 reach break-off signal, this heater power source is just cut off by temperature detect switch (TDS) 42, stop heating at once, guaranteed that fuel oil can not be under the lasting heated condition, has guaranteed the safety in utilization of fuel oil.
