Problems solved by technology

This leads to many hidden dangers. First, the electric heating plate is too much affected by man-made, natural and random combination factors, so it is difficult to judge the quality of various products. 1. The heating wire floor is in the midst of contention among a hundred schools of thought, each saying its own good; the second is that a variety of materials with different functions are compounded together. For example, when heated, the linear expansion coefficients of different materials are different, and the board surface will warp and deform; Metal, inorganic, and organic materials are combined together, which is difficult to maintain and recycle; fourth, the combination of materials with different specific gravity is not only heavy, but also thick. professional installation

Embodiment Construction

[0043] In this patent background analysis and specification attached Figure 1-4 The 4 disclosed patents on the method of making electric heating panels or floor heating, compared with the production of electric heating panels or floor heating in this patent, except for the heating elements and their temperature control systems, the rest of the laying, bonding, assembling, pressing The multiple and multi-layered wrapping materials are all replaced by a two-layer foamed aluminum plate with different upper and lower functions, which can achieve the following common technical effects: First, the production material is reduced from multiple to one, and from multi-layer sandwiches to The upper and lower layers are sandwiched, and the production method and process are greatly simplified; the second is light weight, foamed aluminum is lighter than any material selected in the 4 patents, and the construction and installation are very convenient; the third is the only one that can use m...

Abstract

The invention relates to the technical field of electric-heat conversion, in particular to an electric heating board manufactured by nesting heating elements in foamed aluminum. Multifunctional foamed aluminum structural materials are adopted to replace various and multi-layer materials having different functions and composited on a heating element, the heating elements are nested in the foamed aluminum structural materials, and therefore various defects existing in an existing electric heating board are eliminated. The foamed aluminum is composed of a porous metallic aluminum framework, an aluminum oxide film arranged on the outer surface of the framework in a covering mode and air bubbles inside the framework, integrates the superior performance of metallic aluminum, the superior performance of nonmetallic aluminum oxide and the superior performance of air, has the functional and structural advantages of being light, multifunctional, environmentally friendly and designable, and is an ideal engineering material for improving the cost performance of electric heating boards.

Description

[0001] The invention relates to the technical field of electrothermal conversion, in particular to an electric heating plate made of foamed aluminum nested heating elements. Background technique [0002] Existing electric heating boards or electric floor heating are all products made of compound metals and non-metallic materials with heating elements as the heart. Patent No. 2007100559294 discloses a method for making a small electric heating plate, which consists of a box-shaped plate made of a metal plate, a non-woven fabric to prevent dust, a natural charcoal layer embedded with a ceramic heating element, a non-woven fabric fiber layer, and a lower outer layer material , the upper outer layer material, and the old window-like essential backing plate are pressed and bonded; Patent No. 20113547401 discloses an electric heating floor including a porous insulating fireproof material layer, which consists of a floor base material layer, a thermal diffusion layer, and a conductive...
