Described mozzle comprises many straight tubes and Duo Gen bending tube, and the two ends of described bending tube connect the straight tube described in respectively, the central axis of described straight tube and the centerline axis parallel of described casing ontology; At this, bending tube can adopt existing U-tube.
The central axis of described feed tube and the central axis of described drain pipe all with the centerline axis parallel of described casing ontology; During enforcement, feed tube is connected with a wherein straight tube, and drain pipe is also connected with a wherein straight tube.
On the outer wall of described casing ontology, turning vertically has the groove of strip, and the locus of described groove is between the straight tube described in adjacent two; At this, the weight that groove not only can reduce casing is set, and the storing stability of casing can be increased.
On the outer wall of described casing ontology, integrally casting has terminal box mounting platform; At this, the setting party of terminal box mounting platform the installation of terminal box.
Compared with prior art, the utility model has the advantage of:
1) casing ontology, liquid cooling conduit, feed liquor liquid cooling joint and the disposable hot investment casting of fluid liquid cooling joint complete, and structure is simple, and manufacture is simple easily, manufacturing procedure is few.
