By technique scheme, the beneficial effects of the utility model are：

1st, in the fabrication stage, early stage need not weld water route in narrow space to bending segment frames, significantly reduces welding difficult Degree；Chassis body just welds water route after processing, and the pipe after change opens up aperture in tram on the upper surface of which in advance, Pipe is penetrated by the perforate on the riser of the chassis body two ends outermost left and right sides, then pipe two ends respectively with vertical plates on both sides The water-in and water-out square tube phase weldering at place connects water route with this, finally using little bend pipe by bearing block and circular pipe communicated, completes whole framework The installation in water route and welding.

2nd, bending segment frames in the fabrication stage, do the water pressure test without monolithic riser, need not scarfing cinder repeatedly, save assembling Time, shorten the product manufacturing cycle；Because pipe is just welded after chassis body annealing, it is to avoid produce intercrystalline corrosion existing As effectively improving equipment on-line service life.

3rd, after square tube uses pipe instead, in the case of phase same material and same cross-sectional area, pipe surface of internal cavity amasss and compares square tube Greatly, so dispersion pressure is little, frictional resistance is also just little, and flow velocity is just fast, good cooling results；Pipe can rotate in welding, begins Ensure downhand welding job state (solder side is up) eventually, reduce welding difficulty.

Even if 4 equipment on-lines occur drainage it is only necessary to take off leak water cooling tube, re-replace, reduction equipment returns Repair difficulty.
