Abstract
The utility model discloses a controllable fixed point uniform electric heating device which is used in model tests, and which has good insulation performance and high security. The controllable fixed point uniform electric heating device includes an insulative heat-resisting substrate (1), a plurality of electric heating plates (2) which are arranged on the insulative heat-resisting substrate (1) in a parallel manner, insulative heat-resisting surrounding plates (3) which are connected at the edges of the electric heating plates (2), and an electric wire supply inlet (4) and an electric supply wire outlet (5) which are arranged on the insulative heat-resisting surrounding plates (3), wherein the electric heating plates (2) are connected with a temperature control unit (6). With the controllable fixed point uniform electric heating device, not only uniform heating is achieved, but also independent heating and temperature control for each electric heating plate are achieved, so that fixed point heating is achieved, and continuity of heating and accuracy of fixed point heating are guaranteed.
Description
Technical field
The utility model relates to a kind of model test electric heater unit, the even electric heater unit of controlled fixed point in especially a kind of good insulating, safe model test.
Background technology
In model test, conventionally need electric heater unit to heat tested model.Existing electric heater unit is to be provided with a monoblock electric boiling plate, at the electric heating layer of electric boiling plate, covers one deck silicon rubber or glass fibre outward as insulator.Silicon rubber is easily aging, and the heating layer that makes electric boiling plate is exposed and directly contact with being heated model, thereby causes electric leakage and fire incident; Glass fibre can not be combined closely with heating layer, therefore can not be really and exterior insulation, also exist potential safety hazard.In addition, also exist heating inhomogeneous and be difficult to realize the problem that fixed point adds thermal control.
Summary of the invention
The utility model is in order to solve the existing above-mentioned technical problem of prior art, and the even electric heater unit of controlled fixed point in a kind of good insulating, safe model test is provided.
Technical solution of the present utility model is: the even electric heater unit of controlled fixed point in a kind of model test, it is characterized in that: have insulation heat resistant substrate, there are a plurality of electric boiling plates that are in parallel insulation is evenly distributed on heat resistant substrate, be connected to the heat-resisting coaming plate of insulation with the periphery of electric boiling plate, on the heat-resisting coaming plate of described insulation, have power line entrance and power line outlet, each electric boiling plate all joins with temperature control unit.
Between the heat-resisting coaming plate of described adjacent insulation, there is spacing, be positioned on the insulation heat resistant substrate at spacing place and have wiring groove.
Each electric boiling plate all joins with temperature control unit.
Between the heat-resisting coaming plate of described adjacent insulation, there is spacing, be positioned on the insulation heat resistant substrate at spacing place and have wiring groove.
Described electric boiling plate is the square of 10 * 10cm, is matrix and arranges.
Spacing between the heat-resisting coaming plate of described adjacent insulation is 1cm.
The utility model is the heating unit that on whole insulation heat resistant substrate, a plurality of heat-conducting mediums with air is set, is separated by with the heat-resisting coaming plate that insulate, homogeneous heating not only, and can be as required, realization is to the independent heating of each electric boiling plate and control temperature, thereby realize fixed point heating, guarantee the continuity of heating and the accuracy of fixed point heating thereof; The characteristics such as the heat-resisting coaming plate of set insulation (bakelite plate) has insulation, do not produce static, wear-resisting and high temperature resistant, therefore have good insulating properties, can prevent from occurring because of accidents such as electric leakage that poor insulativity causes, fire.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the partial sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As Fig. 1, shown in 2: have and take the insulation heat resistant substrate 1 that bakelite plate is material, on insulation heat resistant substrate 1, be bonded with and be 81 electric boiling plates 2 that matrix (9 * 9) is arranged, what each electric boiling plate 2 was 10 * 10cm is square, be connected to and take the heat-resisting coaming plate 3 of insulation that bakelite plate is material with the periphery of electric boiling plate 2, insulate and have power line entrance 4 and power line outlet 5 on heat-resisting coaming plate 3, power line joins with electric boiling plate 2 through power line entrance 4 and power line outlet 5, at power line entrance 4 and power line, export 5 places and with insulating cement, power line is fixed and sealed gap, each electric boiling plate 2 all with temperature control unit 6(temperature detect switch (TDS), single-chip microcomputer etc.) join.The heat-resisting coaming plate 3 that insulate is trapped among electric boiling plate 2 wherein, forms to take a plurality of heating units that are in parallel that air is heat medium.The spacing 7 that has 1cm between the heat-resisting coaming plate 3 of adjacent insulation, is positioned on the insulation heat resistant substrate 1 at spacing 7 places and has wiring groove 8, available insulating cement by power line fixed closed in wiring groove 8.
Claims (4)
1. the even electric heater unit of controlled fixed point in a model test, it is characterized in that: have insulation heat resistant substrate (1), at the upper evenly distributed a plurality of electric boiling plates (2) that are in parallel that have of insulation heat resistant substrate (1), be connected to insulation heat-resisting coaming plate (3) with the periphery of electric boiling plate (2), on the heat-resisting coaming plate of described insulation (3), have power line entrance (4) and power line outlet (5), each electric boiling plate (2) all joins with temperature control unit (6).
