WGLL Rank tubes cooler has horizontal and vertical type is applied in metallurgy , mine ,light industry ,food industry etc. to cool the lubricant and hydraulic oil in the lubrication system and hydraulic system. The heat transfer adopts ; for the WGLCQ type is wing tube ,and water side passage with two tube range stuffing box and floating tubes ; for the WGLLQ type is bare tube ,water-side passage adopts tow tube range or four tube range stuffing box and floating tubes ; and WGLLQ5、WGLLQ6、WGLLQ7 series are vertical type. The media viscidity is 10～460mm2/s,working temperature lesser than 100℃.
