The existing transpiration-cooled air cooled fin tube in surface that is suitable for has the physa pipe wound finned tube that Beijing benefit is U.S. high, and a pitch of fins is 7mm, and sheet height is 8mm, galvanizing by dipping, because wing is than little, heat exchange area increases limited, so water-saving result is not obvious, and the windage of physa pipe is comparatively large, unfavorable to Fan Energy-saving.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of novel transpiration-cooled air cooled fin tube in applicable surface.
A kind of novel transpiration-cooled air cooled fin tube in applicable surface of the present utility model, it comprises oval heat exchange base tube, rectangular fin, spacing spoiler, spoiler, flow-disturbing hole, oval heat exchange base tube is arranged with several rectangular fin, the medial surface of rectangular fin is evenly provided with several spacing spoiler and spoiler, rectangular fin is evenly provided with several flow-disturbing hole, and the flow-disturbing hole site of adjacent two rows in front and back is different.
As preferably, described oval heat exchange base tube adopts oval steel pipe to make, and its length external diameter is 100mm*20mm, and wall thickness is 1.5mm, and material is Q235B.
As preferably, described rectangular fin is of a size of 119mm*49mm, and sheet is thick is 0.35mm, pitch of fins 1=7.0mm, pitch of fins 2=5.0mm.
As preferably, be made by galvanizing by dipping treatment process between described oval heat exchange base tube and rectangular fin, galvanizing by dipping is an important step in steel pipe steel fin heat exchange pipe production process, zinc-plated effect has two: one to be the resistance to corrosion improving heat exchanger tube entirety, increases the service life; Two is the contact heat conductien resistances reducing base tube and fin, strengthens heat-transfer effect; And after galvanizing by dipping processing, rectangular fin and oval heat exchange base tube almost combine together, so can adopt the dirt in high pressure water cleaning fin and set of heat exchange tubes.
The beneficial effects of the utility model: its structure is simple, reasonable in design, simple to operate, easy to use, frost-cracking-preventing ability is strong, good energy-conserving effect, can not only clear up the dirt on fin fast, can also bear the ability more than twice thermal cycle every day, adopt oval heat exchange base tube, length radius ratio reaches five times, identical heat exchange area with during identical wind speed than the little twice of pipe windage more than, can effectively reduce power of fan more than 50%.

The oval heat exchange base tube of 1-; 2-rectangular fin; The spacing spoiler of 3-; 4-spoiler; 5-flow-disturbing hole.
Detailed description of the invention:
As Figure 1-Figure 4, this detailed description of the invention is by the following technical solutions: it comprises oval heat exchange base tube 1, rectangular fin 2, spacing spoiler 3, spoiler 4, flow-disturbing hole 5, oval heat exchange base tube 1 is arranged with several rectangular fin 2, the medial surface of rectangular fin 2 is evenly provided with several spacing spoiler 3 and spoiler 4, rectangular fin 2 is evenly provided with several flow-disturbing hole 5, and the position, flow-disturbing hole 5 of adjacent two rows in front and back is different.
Wherein, described oval heat exchange base tube 1 adopts oval steel pipe to make, and its length external diameter is 100mm*20mm, and wall thickness is 1.5mm, and material is Q235B; Described rectangular fin 2 is of a size of 119mm*49mm, and sheet is thick is 0.35mm, pitch of fins 1=7.0mm, pitch of fins 2=5.0mm; Be made by galvanizing by dipping treatment process between described oval heat exchange base tube 1 and rectangular fin 2, galvanizing by dipping is an important step in steel pipe steel fin heat exchange pipe production process, zinc-plated effect has two: one to be the resistance to corrosion improving heat exchanger tube entirety, increases the service life; Two is the contact heat conductien resistances reducing base tube and fin, strengthens heat-transfer effect; And after galvanizing by dipping processing, rectangular fin and oval heat exchange base tube almost combine together, so can adopt the dirt in high pressure water cleaning fin and set of heat exchange tubes.
This detailed description of the invention is when zinc-plated, the closed at both ends of oval heat exchange base tube 1, inner air tube expanded by heating, the effect producing expanded joint between oval heat exchange base tube 1 and rectangular fin 2 can be made, for augmentation of heat transfer, rectangular fin 2 has flow-disturbing hole 5, and the position, flow-disturbing hole 5 of adjacent two rows in front and back is different, and the suspender vibrations of finned tube in zinc pond and after going out zinc pond are very crucial, during leaching zinc, vibrations can promote that zinc enters between rectangular fin 2 and oval heat exchange base tube 1, not only make rectangular fin 2 reach atom level with oval heat exchange base tube 1 to be combined, reduce thermal resistance to greatest extent, and can guarantee anticorrosion without dead angle, finned tube shakes and the sagging between each fin can be removed when going out zinc pond, make the smooth windage of zinc layers little.
This detailed description of the invention prevents from occurring in pipe in winter that recirculated water flowing velocity inequality causes windward side, local heat exchanger tube to freeze, the spacing of fin of windward side ground floor finned tube be greater than second and third, four layers, with the intensity of cooling of balanced four layers of heat exchanger tube, prevent windward side ground floor from freezing because intensity of cooling crosses strong, simultaneously for preventing the dust in air from producing bridging phenomenon under the effect of water, cause between fin and block, the spacing of fin of four layers of finned tube is all greater than pure air-cooled heat exchanger; Because the exothermic coefficient of pipe Inner eycle water is higher, it not the main restricting factor of heat transfer process, and summer is under shower water evaporation and heat-exchange pattern, the exchange capability of heat of air side is also better than emission capacity in pipe, so the convection transfer rate of air side when the heat transfer property of heat exchanger tube depends primarily on Winter Dry air cooling, and the convection transfer rate of air side and face velocity have close relationship; The pitch of fins first row of finned tube is 7.0mm, rear three rows are 5.0mm, base tube triangular form is arranged, the heat of pipe Inner eycle water is passed to fin by the mode of heat conduction by base tube, base tube and fin transfer heat to outer air of plunderring by the mode of convection current again simultaneously, therefore, the heat transfer of heat exchanger tube is the diabatic process that cross-ventilation heat transfer and solid conductive heat intercouple.
This detailed description of the invention structure is simple, reasonable in design, simple to operate, easy to use, frost-cracking-preventing ability is strong, good energy-conserving effect, can not only clear up the dirt on fin fast, can also bear the ability more than twice thermal cycle every day, adopt oval heat exchange base tube, length radius ratio reaches five times, identical heat exchange area with during identical wind speed than the little twice of pipe windage more than, can effectively reduce power of fan more than 50%.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
