风道式电加热器

风道式电加热器主要用于风道中的空气加热,规格分低温、中温、高温三种形式,在结构上的共同之处是采用了钢板支撑电热管以减少风机停止时电热管的振动,在接线盒中都装有温控装置。
The air duct electric heater is mainly used to heat the air in the air ducting. It has three models of low tempt, medium tempt and high tempt. One common thing in terms of structure is that they adopt steel plate for supporting in order to reduce vibration of electric heating tubes when fan stops. Connection boxes are fitted with tempt controllers.

??? 其中低温型加热器可直接安装在风道上,如下图1,而中温型、高温型由于使用温度较高,与低温型加热器采用不同的结构,即在通道外璧至加热器接线盒之间设置一定的保温。
Of these models the low temperature heater can directly be installed on the duct as in fig 1. While the medium and high temperature heaters need certain insulation between the outer wall of the duct and the terminal connection box, as they are subjected to higher temperature and adopt a different structure.

??? 如下图2、图3,一方面减少整个通道的对外散热,另一方面也减少了接线腔内的温度,因此中、高温通道加热器的安装,必须在通道上先设置安装框(如图4)。低、中温型加热器采用翅片式电热元件,高温加热器采用管状元件。
As in fig 2 and fig 3. That way the heat diffusion of the entire ducting is reduced and on the other hand, temperature inside the terminal box is also reduced. That is why medium and high temperature heaters need a mounting frame to be set on the ducting as in fig 4.for their installation. Low and medium temperature heaters have wing shape heating elements and high temperature heater has tubular heating elements.



?型号含义:
? The type signifies:

??? 通道式电加热器配以离心风机、电控柜,并装于移动小车上,成为移动式电热风机。可用于容器或管道内吹干水份,化工管道、阀门局部解堵、解冻等。电热风机操作维护方便,应用广泛。
