Manufacture method for positive temperature coefficient devices and anti-overheating system for plane heating element

Abstract

The invention discloses a manufacture method for positive temperature coefficient devices and an anti-overheating system for a plane heating element, comprising steps of mixing one or more than two polymer resins, carbon blacks and additives selected from ethylene butyl acrylate monomer copolymer, ethylene vinyl acetate copolymer, and polyoxyethylene, squeezing the mixed composite into a thin-film shape and adhering electrodes to the two sides, and irradiating electron rays to perform crosslinking processing. Then, the plurality of positive temperature coefficients are in a serial connection to be used as anti-overheating sensor cables of a plane heating element controller and are adhered to the surface of the heating element in certain spacing, the positive temperature coefficient anti-overheating sensor cables are in a bending arrangement toward any direction at a position using the plane heating body, therefore, the positive temperature coefficient devices are in a scattering arrangement at any position. When heating phenomenon is generated at the part adhered by positive temperature coefficients and the surrounding area due to abnormal operation, power on of the plane heating body is controlled, thereby improving anti-overheating safety, saving energy, facilitating construction, saving cost and improving durability.

Description

technical field [0001] The present invention relates to a positive temperature coefficient (Positive Temperature Coefficient, PTC) device manufacturing method and a planar heating body anti-overheating system using the above-mentioned positive temperature coefficient device, and a plurality of positive temperature coefficient devices connected in series are used as an anti-overheating sensor of a planar heating body controller. Therefore, when overheating (or heat storage) occurs, the power supply of the planar heating element is controlled to improve the safety of the planar heating element. Background technique [0002] So far, most of the ground heating and other heating devices widely used are heating devices using fossil fuels such as oil and natural gas. Due to the serious problem of depletion, people are paying more and more attention to heating devices using alternative energy sources, and research and development are being carried out continuously, so that electric ...

AI Technical Summary

Problems solved by technology

If one of the multiple temperature sensors is abnormal, it will affect the entire system. Therefore, it is difficult to find the best heating conditions, and the reality is poor.

In addition, due to the complex structure of the floor heating system, it is difficult to install and construct, and the construction cost is relatively high.

[0009] In addition, PTC (Positive Temperature Coefficient, positive temperature coefficient) heating elements (positive temperature coefficient heating elements) are mainly small heater components with narrow electrode spacing, and heating products are used for construction in a small area, but the cost is relatively high. High, and most of the products are low voltage products

The reason is that if a high voltage (AC100V or more) is repeatedly applied to heat the positive temperature coefficient heating element, the product is easily damaged due to the deterioration of the positive temperature coefficient heating element and the repetition limit of the positive temperature coefficient device.
