Embodiment 1

[0018] Figure 1-A The structure of the first electric heating sheet material layer provided by the embodiment of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0019] The material layer of the electric heater includes:

[0020] The first insulating layer 11 is used for insulating and protecting the constantan foil;

[0021] The heating layer 12 made of constantan foil, the first surface is connected to the first insulating layer 11, and is used to generate heat after electrification;

[0022] The second insulating layer 13, the first surface of which is connected to the second surface of the heating layer 12, is used for insulating and protecting the constantan foil;

[0023] The first adhesive layer 14, the first surface of which is connected to the second surface of the second insulating layer 13, is used to bond the heat equalizing layer 15 and the second insulating lay...

Embodiment 2

[0029] figure 2 The structure of the material layer of the second heating sheet provided by the embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0030] In this embodiment, the first insulating layer and / or the second insulating layer adopts a polyimide film, and the polyimide film is thinner and lighter than the traditional electric heater insulating layer, so when polyimide When the film is used as an insulating layer and constantan foil as a heating layer, the thickness and weight of the heating element can be reduced more effectively, so that the heating element can meet the requirements of defense electronic products, aerospace equipment, portable medical instruments, high-density electronic equipment, etc. Heating requirements for applications that require more sophisticated instruments or equipment.

[0031] In addition, the polyimide film can better protect t...

Embodiment 3

[0034] Figure 4 A structural diagram of the electric heater provided by the embodiment of the present invention is shown, and only parts related to the embodiment of the present invention are shown for convenience of description.

[0035] The electric heating sheet is composed of a heating sheet 41 and a conductive wire 43 , and the joint of the conductive wire 43 and the heating sheet 41 is pressed together by a high temperature resistant glue 42 . By adopting this method, no space is left around the conductive wire, so as to better protect the conductive wire from being disconnected.

Abstract

The invention is applicable to the field of heating device design, and provides an electric heating piece, an electric heating device and equipment, wherein the electric heating piece comprises a first insulating layer, a heating layer which is connected with the first insulating layer, a second insulating layer which is connected with the heating layer, a first bonding layer which is connected with the second insulating layer, a uniform heating layer which is connected with the first bonding layer and a second boding layer which is connected with the uniform heating layer, and the heating layer is constantan foil. The electric heating piece selects the constantan foil as the heating layer, so the thickness of the electric heating piece is reduced, and the electric heating piece can be applied in an application range with higher precision; and meanwhile, the heat transfer efficiency of the electric heating piece is also improved, and accordingly, the power and the preheating speed of the electric heating piece are improved.

Description

technical field [0001] The invention belongs to the field of heating device design, and in particular relates to an electric heating sheet, an electric heating device and equipment. Background technique [0002] Electric heaters have been widely used in medical, military and daily life fields due to their lightness, compactness and relatively simple manufacturing process. On the other hand, because the material of the existing electric heating sheet is too thick, there are problems such as the limitation of the application range, and at the same time, due to the low heat transfer efficiency of the existing electric heating sheet, the gap formed between the resistance element and the radiator The heat difference is large, which leads to problems such as low power of the electric heater and slow warm-up speed. Contents of the invention [0003] The purpose of the embodiment of the present invention is to provide a heating plate, aiming to solve the problem of the large appl...
