Abstract

The invention discloses a diesel oil filter heating device of an integrated contact type fuel oil temperature sensor. A guiding pipe is designed outside a heating element of the heating device, and fed oil can flow through the heating element to fully absorb heat and be heated through a backflow pipe. A temperature sensing element installing groove is designed on the outer side of the guiding pipe to enable a temperature sensing element to be directly in contact with the fed oil and timely sense the real temperature of the fed oil. The problem that the fuel oil is unevenly heated due to the existing insufficient design or a heater works when being not need and cannot perform heating when being needed is solved, meanwhile the accuracy degree of the temperature sensing element is improved, the service life of relevant elements is prolonged, energy consumption is reduced, and a vehicle can normally run.

Description

technical field [0001] The invention relates to the field of automobile filters, in particular to a filter heating device integrated with a contact type fuel temperature sensor. Background technique [0002] At present, the car preheating system currently in use in the market cannot solve the problem of mutual interference between the temperature sensing element and the heating element and can only be solved by a split design, which will greatly reduce production efficiency and increase costs. Most of the car preheaters In use, the metal shell is used to wrap the heating element. In this way, the heat of the heating element cannot be fully dissipated, and it cannot heat all the input oil well. It can only heat the oil flowing through its surroundings, and use The temperature sensors on the automotive filter are all non-contact, that is, the temperature sensing device is in contact with the casing and then the casing is in contact with the fuel to sense the temperature, which...
