The utility model provides a flat heater, which comprises a substrate, a heating wire body penetrated on the substrate, two insulating plates arranged on the upper and lower surfaces of the substrate and a shell sheathed on the outer surfaces of the two insulating plates. The substrate is an insulating plate, on which a plurality of perforations are arranged in a plurality of rows along the longitudinal direction of the substrate, and the heating is described. The wire body is arranged in succession up and down in each perforation along the longitudinal direction of the substrate, and the two ends of the wire are connected with a power cord respectively. The substrate and the insulating plate are mica plates, and the shell is a flat cylinder. The flat heater is flat in shape to increase its contact area with the outside world, and the heating wire body is fixed on the substrate due to the perforation arranged on the substrate, and the heating wire body is fixed on the substrate in order to increase the area of the heating wire body and improve the heating property.

扁平状加热器
本技术涉及一种加热
,尤其涉及一种扁平状加热器。
技术介绍
目前的高温操作平台包括操作平台、加热管和保温层三个部分,由于其采用加热管进行加热,整个高温操作平台比较笨重;同时由于加热管是圆型的,与操作平台是线接触,其传热面积小,由此使得操作平台的温度不均匀,温差大,并容易出现过热点,有待于改进。
