风道式加热器

风道电加热器概述
    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用钢板支撑电热管以减少风机停止时电热管的振动，在接线盒中都装有超温控制装置。低温型可直接安装在风道上，而中温型、高温型由于结构上的不同，在通道外壁至加热器接线盒夹有100mm 厚的保温材料，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。

Overview of duct heater

Air heater is mainly used for air duct in heating, specifications at low temperature, low temperature and high temperature in three forms, in the common structure is supported by a steel plate used to reduce the electric fan at the end of the electric vibration tube, in the junction box are equipped with ultra temperature control device. Low temperature can be directly installed in the air duct, and the medium temperature, high temperature due to structural differences in access to the outer wall heater junction box with 100mm thick insulation material, on the one hａnd to reduce the access of external cooling, on the other hａnd also reduces the wiring cavity temperature.

风道电加热器结构
　　1.风道加热器采用不锈钢加热管作为发热体
　　2.采用碳钢或者不锈钢材料做支架
　　3.采用组合式的连接方式构成

Air duct electric heater structure

1 air duct heater is made of stainless steel heating tube

2 use carbon steel or stainless steel as support

3 using a combination of connection form

风道电加热器产品特点
　　1．电加热管采用外绕波纹式不锈钢带，增加了散热面积，大大提高了热交换效率。
　　2．加热器设计合理，风阻小，加热均匀，无高、低温死角。
　　3．双重保护，安全性能好。在加热器上安装了温控器、熔断器，可以用来控制风道空气温度超温和无无风的情况下工作，确保。

Air duct electric heater product features

1 the electric heating tube adopts the external corrugated stainless steel belt, which increases the heat dissipation area and greatly improves the heat exchange efficiency.

The 2 heater is reasonable in design, small wind resistance, uniform heating, high temperature, no dead.

3 double protection, good safety performance. Install thermostat, fuse on the heater can be used to control the wind, air temperature without super mild calm under the circumstances, to ensure that no danger of anything going wrong.
