Abstract

The utility model relates to a silastic heater which is characterized in that the an electric heating layer is arranged on the silastic heater; the electric heating layer is formed by arranging a heating cord disc in an alkali-free glass fiber layer; and a silastic layer is respectively agglutinated on the upper surface and the lower surface of the electric heating layer, wherein an aluminum alloy plate is agglutinated on one silastic layer, a power socket is installed on the other silastic layer, and a lead connected with the anode and the cathode of the power socket is respectively connected with the anode and the cathode of a heating cord after passing through the silastic layer. The utility model has flat type and ultra-thin characteristic by combining aluminum alloy and silastic through a special technology; the silastic heater has good heating effect, fast heating, high thermal efficiency and long service life because a heating body adopts nichrome wires. Double insulation of the dampproof silastic and the alkali-free glass fiber enables the insulating performance of the silastic heater to be more reliable. The aluminum alloy plate is adopted for assisting radiation, so the silastic heater has higher thermal efficiency, longer service life and convenient installation.

Description

Silicon rubber heater

Technical field:

The utility model relates to a kind of heater, specifically relates to a kind of silicon rubber heater.

Background technology:

The cabinet heater generally is used for the heating and the insulation of cabinet, casing, for example switch cubicle, communication counter, illumination cabinet, anti-condensation case, computer casing etc.The insulation of the cabinet heater of prior art and heat sinking function are not very good.

Summary of the invention:

The utility model provides a kind of silicon rubber heater, and its purpose is to solve the prior art defective, provides that a kind of heating is fast, the heat efficiency is high, double insulation, the silicon rubber heater of long service life.

The technical solution of the utility model is:

A kind of silicon rubber heater, it is characterized in that: have electrothermal layer, electrothermal layer is located in the alkali-free glass fibre layer by the electric filament disc and is constituted, at each bonding silastic-layer of electrothermal layer upper and lower faces, be bonded with aluminium alloy plate on the silastic-layer therein, on another silastic-layer, supply socket is installed, is connected with the both positive and negative polarity of heating wire respectively after the lead that the both positive and negative polarity of supply socket connects passes silastic-layer.

Described heating wire is nichrome wire (also can be Ka Masi, pure nickel wire, constantan wire, copper nickel wire, iron and iron metal exothermic materials such as silk).

The utility model combines aluminium alloy and silicon rubber by special technology, has flat ultra-thin characteristics, and this silicon rubber heater heats is good, and heater adopts nichrome wire, and heating is fast, heat efficiency height, long service life.Prevent humidifying silicon rubber and alkali-free glass fibre double insulation, make described silicon rubber heater insulation property more reliable.Described aluminium alloy plate auxiliary heat dissipation improves the heat efficiency of described silicon rubber heater, and prolongs its useful life, and is easy for installation.
