SEMEM_SRZ散热器
一、SRZ钢制散热器概述
1.SRZ钢制散热器按照标准图集生产,结构紧凑,气密性好,安装方便;
2.SRZ钢制散热器主要由顺空气流向的三排翅片管叉排组成,SRZ钢制散热器翅片管均用Ф22×2mm无缝钢管绕制上16×0.5mm皱折钢带而成,呈螺旋状,翅片管片距有5mm-大“D”,6mm-中“Z”、8mm-小“X” 三类;
3.SRZ型钢制散热器是一种既适用于蒸汽系统、又适用于高温热水系统中,作为加热空气用的钢制散热器,主要用于热风采暖、空气调节系统及干燥装置的空气加热;
4.SRZ型钢制散热器型号表示:
SRZ①×②③
①—表示钢制散热器长尺寸分米化整
②—表示钢制散热器宽尺寸分米化整
③—表示钢制散热器散热能力的大小(大D,中Z,小X)
