怎样解决防爆配电箱散热问题

1、防爆配电箱的防爆处置

因为防爆配电箱所运用的环境有性气体或粉尘较多，这就需求防爆配电箱密封防爆，所以它的外壳不能用一般的壳体，必需用规范的防爆腔，把防爆配电箱一切的元件都装在防爆腔内。在防爆腔门上开一个观察窗，把显现有些装在上面，把发动、中止、调速操控装在防爆腔门上。

2、防爆配电箱的散热处置

防爆配电箱散热疑问因为防爆配电箱的一切元件都装在隔爆型防爆腔内，空气不能活动，散热疑问变成防爆配电箱所要解决的关键疑问。在这里咱们采用了一种新的散热技能-热管散热技能。

(1)热管技能原理热管是一种具有极高导热功能的传热元件，它经过在全封闭真空管内工质的蒸腾与凝结来传递热量，具有极高的导热性、杰出的等温性、冷热两侧的传热面积可任意改动、可远距离传热、可操控温度等一系列长处。由热管组成的换热器具有传热效率高、构造紧凑、流体阻损小等长处。

(2)变频器构造安置咱们将主回路规划成一个大单元，安装在长方形防爆腔内后壁，后壁上经过一个过度散热器与IGBT模块、整流模块等发热元件接合，防爆外壳外壁加焊槽形散热器，过度散热器与槽形散热器经过热管相连接。变频器内部发生的热量就经过防爆腔后壁过度散热器热管槽形散热器发出出去。

Explosion proof, explosion-proof distribution box 1

Due to the use of the explosion-proof box environment more explosive gas or dust,which requires the explosion-proof box sealed explosion-proof housing, so it cannotuse ordinary housing, must use explosion-proof cavity standard, the explosion-proofbox all components are arranged on the explosion cavity. Open a window in the explosion-proof chamber door, the display part is arranged on the top, start, stop,speed control is arranged in the explosion-proof chamber door.

Heat treatment 2, explosion-proof distribution box

The explosion-proof distribution box heat problems due to all the components of the explosion-proof distribution box are installed in the flameproof explosion-proof cavity,the air can not flow, the key problems of heat problems become explosion-proofdistribution box to solve. Here we use a heat dissipation technology - the new heat pipe technology.

(1) the technical principle of heat pipe and heat pipe is a heat transfer element withhigh heat conductivity, it closed in vacuum tube refrigerant evaporation and condensation to transfer heat, the heat transfer area has high thermal conductivity,good uniformity, hot and cold sides can be arbitrarily changed, remote heat transfer,can be a the advantages of control temperature. The heat exchanger has theadvantages of high heat transfer efficiency, compact structure, small fluid resistance loss is composed of heat pipe.

(2) converter arrangement we will main circuit design into a large unit, arranged in the rectangular explosion-proof cavity wall, posterior wall by an excessive heat sink and IGBT module, rectifier module heating elements such as joint, explosion-proof enclosure wall welding groove shaped radiator, radiator and excessive trough by heatpipe radiator connection. Transducer internal heat produced by explosion cavity wallexcessive heat pipe radiator radiator gives out groove.
