Description
Technical field
The present invention relates to a kind of flexible electric heater unit and its screed for screed bottom plate heating, belong to paver
Screed technical field.
Background technology
Screed, as a kind of indispensable part on paver, serves more and more important effect.Paver is pressed
The technology development of flat board is also with rapid changepl. never-ending changes and improvements, and new technology emerges in an endless stream.
Being presently used for the technology of screed bottom plate heating mainly has gas to heat and two kinds of electrical heating, and wherein electrical heating is divided into
Stainless steel electrically heated rod and the aluminium sheet that stainless steel electrically heated rod is cast in aluminium sheet heat two kinds, are all integrally fixed at during work and pressed
On flat board base plate, base plate is heated by heat exchange.It is nichrome heating wire inside stainless steel heating rod, outside is stainless
Steel pipe, inserts is magnesia powder material, and it has the disadvantage that heat transfer area is smaller so that screed base plate has Same Efficieney
Lower firing rate is slow, baseplate temp is uneven causes the problems such as deforming；Electrical heating aluminium sheet heat transfer area is big, heating-up temperature
Than more uniform, but it is larger to there is volume and weight, causes heat to scatter and disappear also big, not the shortcoming of energy-conservation.
The content of the invention
Purpose：In order to overcome the deficiencies in the prior art, the present invention provides a kind of for screed bottom plate heating
Flexible electric heater unit, can realize screed base plate under Same Efficieney firing rate faster, heating-up temperature evenly.
