Utility model content
The purpose of this utility model is the tubular heater providing a kind of built-in thermel protection device, is applicable to metal PTC and electric heating tube, to solve the problem.
The tubular heater of built-in thermel protection device, comprise an electric heater main body, described electric heater main body comprises at least one heating tube for heating, described heating tube left end is provided with the first eduction rod, described heating tube right-hand member is provided with the second eduction rod, it is characterized in that, in described heating tube, be provided with a thermel protection device;
The left end of described thermel protection device connects described first eduction rod by the first heating wire, and the right-hand member of described thermel protection device connects described second eduction rod by the second heating wire.Thermel protection device is arranged in heating tube by the utility model; can fuse in time after reaching design temperature; by cutting off the current channel in heating tube, avoid high temperature to continue or temperature continues to rise, and then the too high equipment burnout that causes of heating tube temperature or damage can be avoided.
In order to make stable connection, reduce resistance, two ends of described thermel protection device are equipped with external screw thread.To be connected with heating wire by external screw thread, and spot welding or other weldings are fixed.
As a kind of preferred version, described thermel protection device can be a hollow thermel protection device, and described hollow thermel protection device is provided with a cavity.Its advantage one; arranging of cavity can make thermel protection device when melting; section has retraction space, and then avoids the too small thermel protection device conducting again causing fusing in heating tube space, its advantage two; during fuse fusing; cavity provides enough spaces, allows and deposits melt, can avoid melt and tube wall conducting; cause and puncture, work the mischief.
The preferred shuttle shape of outline of hollow thermel protection device.To improve the uniformity that the draw overstocks the distortion caused in process.
Described thermel protection device is preferably placed at the middle part of described heating tube.To control the temperature of heating tube more accurately.
Described thermel protection device is preferably placed at the left part of described heating tube
