Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Fig. 1～Fig. 7, horizontal immersion coil cluster case type feed-water heater of the present utility model includes housing 1, coil 7 and the header being attached thereto, thin cold section of heater is provided with the general " l " shape involucrum of monnolithic case 3, described involucrum 3 constitutes the general frame dredging cold section, it is fixed by welding in header on the upside of involucrum 3, involucrum 3 bottom is left, the right side is respectively arranged with a support member 6, described support member 6 is welded by I-steel 5 and round steel 8, I-steel 5 is fixed with involucrum 3 bottom welding, round steel 8 and housing 1 inwall are linear contact lay, so involucrum 3 can not only be played a supporting role, can also be when involucrum 3 and coupled parts be pushed in housing 1, reduce and rub between itself and housing 1 inwall, can smoothly enter in housing 1.Involucrum 3 is internal is disposed with the baffling structure matched with coil 7 mode of assembling, this baffling structure includes eight groups of deflecting bar pipe groups, the deflecting bar pipe 4 constituting described deflecting bar pipe group is nick shaped structure, the size of its breach matches with the external diameter of coil 7, so by coil 7 is fixed securely by coil 7 through the breach on deflecting bar pipe 4, constitute in all deflecting bar pipes 4 of same deflecting bar pipe group are respectively positioned on same plane and be spaced a distance between adjacent deflecting bar pipe 4, the plane at all deflecting bar pipe group places is all vertical with the snakelike tube bank direction dredging cold section, and be spaced a distance between adjacent deflecting bar pipe group, the two ends of all deflecting bar pipes 4 are individually fixed in end face and the bottom surface of involucrum 3 by welding.nullWhen assembling deflecting bar pipe and coil，Owing to can only be assembled and limited by string string by coil，So first one piece of deflection plate of overall processing，Then deflection plate is cut into deflecting bar pipe one by one，Then deflecting bar pipe is assembled smoothly with each column coil，The piecemeal processing and the piecemeal that realize baffling structure assemble，Described baffling structure is made to be easily applied in heater of the present utility model，Simultaneously，Owing to arranging eight groups of deflecting bar pipe groups in dredging the involucrum 3 of cold section，When dredging continuation flow forward in cold section hydrophobic enters into involucrum 3，Hydrophobic flow channel area in involucrum 3 will reduce，Hydrophobic flow velocity in involucrum 3 is increased，So that the hydrophobic heat transfer coefficient to coil increases，Furthermore，All of deflecting bar pipe 4 is all to be fixed by welding on end face and the bottom surface of involucrum 3，The hydrophobic leakage current being so avoided that between deflecting bar pipe 4 and involucrum 3，Further increase the hydrophobic heat transfer coefficient to coil 7 in involucrum 3.
As to a kind of optimization of the present utility model, described housing 1 is provided with a venting mouthpiece 2, described involucrum 3 is provided with an exhaustor 11, then it is connected with described venting mouthpiece 2 and connects formation after described exhaustor 11 being carried out bending process and flexibly connect, so can not only drain the incondensable gas in involucrum 3, moreover it is possible to avoid the exhaustor 11 destruction under thermal (temperature difference) stress effect；In order to realize being connected easily with exhaustor 11 by venting mouthpiece 2, venting mouthpiece 2 is extend in housing 1.
As to further optimization of the present utility model, an inner sleeve 9 it is provided with bottom described involucrum 3, the port of export of this inner sleeve 9 is connected by being welded and fixed with hydrophobic outlet base 10 inwall being arranged on housing 1, so make outside involucrum 3 hydrophobic must be introduced into involucrum 3 in give the heat transfer of all coils 7 after could flow to, outside housing 1, further ensure the heat transfer property of thin cold section from inner sleeve 9.
