Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1, 2 and 3: the utility model provides a diesel oil heater, including both ends open-ended casing 1, casing 1 is the tubulose, casing 1's one end is overhead to have outside protrusion and rather than coaxial setting's fixing base 2, form entry 3 between this end and the fixing base 2, be equipped with temperature switch 4 in the fixing base 2, and its card is equipped with a pair of heating element 5 that sets up and lie in casing 1 about the axis symmetry of casing 1, heating element 5 includes a pair of relative electrode plate 51 that sets up, link firmly heating plate 52 between a pair of electrode plate 51 and with the airtight metal side's pipe 53 including electrode plate 51, specifically, the heating plate is the PTC heating plate. The heating element 5 is provided with a plurality of radiating fins 6 uniformly distributed on the area opposite to the shell 1, and specifically, the metal square pipes 53 and the radiating fins 6 are made of aluminum material. Casing 1 has seted up a pair of 5 relative exports 11 of heating element on keeping away from the lateral wall of fixing base 2, and the joint has assorted cap 7 on the other end of casing 1, is equipped with the PCB circuit board 8 that all links to each other with heating element 5 and temperature switch 4 in the cap 7 to the filling has the epoxy 9 of wrapping up PCB circuit board 8 in, and the surface of cap 7 is equipped with the line control case 10 that links to each other with the PCB electricity. Through this kind of structure, not only make heating area of contact big, the heating plate is isolated with the medium of treating to heat moreover to make this diesel oil heater realize can high-efficient and safely carry out the technological effect of heating to diesel oil.

Further, the radiating fins 6 are of a wave-shaped structure, so that the heating contact area is further enlarged, and smooth flowing of diesel oil is guaranteed.

Further, each electrode plate 51 is covered with an insulating sheet on the back surface of the heating sheet 52, so that the short circuit between a pair of electrode plates 51 is avoided, and the normal operation of the heating assembly 5 is ensured.

Further, the shell 1 and the fixing seat 2 are integrally formed, so that the structure is compact and the strength is high.

Further, the periphery of the shell cover 7 is annularly provided with a connecting flange integrally formed with the shell cover, and the connecting flange is provided with a pair of symmetrically arranged mounting holes, so that the convenience of mounting is improved.

Furthermore, a matched bushing is arranged in each mounting hole, so that the service life is prolonged.

The working principle is as follows: when the diesel oil heating device is used, diesel oil flows into the shell 1 from the inlet 3 and then flows out from the outlet 11 of the shell 1, in the process, the temperature switch 4 monitors the temperature of the fuel oil and sends data to the circuit control box 10 through the PCB, the circuit control box 10 compares the data with a preset temperature value, and if the data is larger than the preset value, the circuit control box 10 controls the heating component 5 to stop working through the PCB; if the temperature is smaller than the preset value, the circuit control box 10 controls the heating component 5 to heat through the PCB so as to enable the diesel oil to be heated.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
