BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of the utility model.

[0017] Figure numerals: box body -1, board body -2, insulation component -3, board body -2 includes outer shell -21, heating layer -22, pasting board -23, aluminum silicate fiber layer -31, rock wool layer -32, polyurethane foam layer -33, aluminum foil layer -34. DETAILED DESCRIPTION

[0018] like Figure 1 As shown, the utility model proposes: a high uniform efficiency heating plate, comprising a box body 1 and a plate body 2, wherein the plate body 2 is in an annular plate shape and its inner side is in contact with the box body 1 (the box body 1 may be an oil tank of an excavator, etc.), and is arranged in an annular manner on the outer side of the box body 1 to provide an annular heating to improve uniformity;

[0019] The plate body 2 is coated with a heat preservation component 3, and the heat preservation component 3 is in contact with the box body 1, so that the plate body 2 is sandwiched between the box body 1 and the heat preservation component 3, and the heat is concentrated in the box body 1 to improve the heat utilization rate;

[0020] In order to implement the above-mentioned thermal insulation component 3, it is proposed that Figure 1 As shown, the specific structure and composition of the heat preservation component 3 can be as follows: the heat preservation component 3 includes an aluminum silicate fiber layer 31 which is attached and fixed to the plate body 2 and attached to the box body 1 (as shown in the figure, the aluminum silicate fiber layer 31 is annular U-shaped and wraps the plate body 2. The attachment position can be fixed by bonding or the like, and at the same time, it is attached to the surface of the box body 1, and has good insulation), (the excellent high temperature resistance and low thermal conductivity of the aluminum silicate fiber layer 31 effectively blocks the heat of the heating plate from being conducted outward);

[0021] The thermal insulation component 3 also includes a rock wool layer 32 which is fixedly attached to the outside of the aluminum silicate fiber layer 31 and attached to the box body 1 (as shown in the figure, the rock wool layer 32 is attached to the outside of the aluminum silicate fiber layer 31, and the attachment position can be fixed by bonding or the like, and at the same time, it is attached to the surface of the box body 1, and has good insulation), (the rock wool layer 32, as a natural material, not only provides good thermal insulation performance, but also enhances the mechanical strength and stability of the thermal insulation structure, and is an insulation layer that can further slow down heat transfer);

[0022] The thermal insulation component 3 also includes a polyurethane foam layer 33 which is fixedly attached to the outside of the rock wool layer 32 and attached to the box body 1 (as shown in the figure, the polyurethane foam layer 33 is attached to the outside of the rock wool layer 32, and the attachment position can be fixed by bonding or the like, and at the same time, it is attached to the surface of the box body 1, and has good insulation), (the extremely low thermal conductivity and excellent sealing performance of the polyurethane foam layer 33 can effectively fill the gaps, improve the overall sealing of the thermal insulation structure, and further reduce energy loss);

[0023] The heat preservation component 3 also includes an aluminum foil layer 34 which is fixedly attached to the outside of the polyurethane foam layer 33 and attached to the box body 1 (as shown in the figure, the polyurethane foam layer 33 is attached to the outside of the rock wool layer 32, and the attachment position can be fixed by bonding or the like, and at the same time, it is attached to the surface of the box body 1, and has good insulation), (due to the reflection principle of the aluminum foil layer 34, the heat exchange caused by radiation is significantly reduced, and the material is light and thin, which can greatly improve the efficiency of the heat preservation system);

[0024] In summary, the advantages of different materials are utilized to form multiple barriers, each layer blocks different heat transfer modes (conduction, convection, radiation), achieving a more comprehensive insulation effect;

[0025] The plate body 2 includes a shell 21 attached to the aluminum silicate fiber layer 31, a heating layer 22 disposed in the shell 21, and a plate 23 fixedly embedded in the shell 21 (the heating layer 22 may be a heating wire, etc.);

[0026] The outer surface of the plate 23 is in contact with the box body 1, and the thermal conductivity of the plate 23 is greater than that of the outer shell 21 (the outer shell 21 can be made of polytetrafluoroethylene, etc., and the material of the plate 23 can be aluminum alloy, etc., to ensure that the heat is concentratedly discharged at the plate 23, and the heat utilization rate is high).

[0027] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
