Description
Technical field
The utility model relates to a kind of oil, gas heat exchanger that mainly but uses on unit in air-cooled oil, air cooling, belongs to technical field of heat exchangers.
Background technology
Air-cooled oil, air cooling but set heat exchange device generally adopt steel pipe to roll several modes such as aluminium flake around steel disc, steel pipe around aluminium flake, steel pipe.When steel pipe is made around aluminium flake around steel disc, steel pipe, adopt steel band or aluminium strip to process on steel pipe, its contact-making surface is little, closeness of contact is strong not, heat exchange efficiency is low; When steel pipe rolls the aluminium flake making, adopt steel, aluminum casing extruding to form, its tube wall is thicker, the aluminium fin is straight, heat exchange efficiency is general, and the heat exchanger contour structures is larger, and the manufacturing cost expense is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of contact-making surface is large, contact closely, but set heat exchange device of air-cooled oil that heat exchange efficiency is high, air cooling.
the technical scheme that provides according to the utility model, described air-cooled oil, air cooling is the set heat exchange device but, comprise heat exchange fin, heat exchanger tube, the heat exchanger tube connecting bend, the first distributing pipe, framework and the second distributing pipe form, heat exchange fin is waveform, be provided with the hydrophilic film corrosion-inhibiting coating at the heat exchange fin outer surface, some heat exchanger tubes are installed in the heat exchanger framework, the import and export of adjacent two heat exchanger tubes are connected by connecting bend is corresponding, the entrance point of first row heat exchanger tube is connected with the first distributing pipe, the port of export of last row's heat exchanger tube is connected with the second distributing pipe, offer installing hole on heat exchange fin, heat exchanger tube is inserted in the installing hole of heat exchange fin, the outer tube wall of heat exchanger tube and heat exchange fin installing hole inwall are interference fit.
Described heat exchange fin is made by metal aluminum foil.
Described heat exchanger tube is made by stainless steel material.
In the utility model heat exchange fin and heat exchanger tube contact-making surface large, contact tight, between heat exchange fin and heat exchanger tube, heat transfer efficiency is high, the advantage such as the utlity model has structure, compactness, heat transfer coefficient is high, heat exchange efficiency good, windage is low, antiseptic property is strong, repair and maintenance is convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of A part in Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
as shown in the figure, this air-cooled oil, air cooling is the set heat exchange device but, comprise heat exchange fin 1, heat exchanger tube 2, connecting bend 3, the first distributing pipe 4, framework 5 and the second distributing pipe 6, heat exchange fin 1 is waveform, outer surface at heat exchange fin 1 is provided with the hydrophilic film corrosion-inhibiting coating, some heat exchanger tubes 2 are installed in framework 5, the import and export of adjacent two heat exchanger tubes 2 are connected by connecting bend 3 according to number of tube passes, the entrance point of first row heat exchanger tube 2 is connected with the first distributing pipe 4, the port of export of last row's heat exchanger tube 2 is connected with the second distributing pipe 6, offer installing hole on heat exchange fin 1, heat exchanger tube 2 is inserted in the installing hole of heat exchange fin 1, the outer tube wall of heat exchanger tube 2 and heat exchange fin 1 installing hole inwall are interference fit, heat exchanger tube is inserted in the installing hole of heat exchange fin, adopt the mechanical expanding technology the installing hole inwall interference swelling of the outer tube wall of heat exchanger tube 2 and heat exchange fin 1.
Described heat exchange fin 1 is made by metal aluminum foil.
Described heat exchanger tube 2 is made by stainless steel material.
The utility model adopts first has punching the heat exchange fin 1 of installing hole to be placed in framework 5, the heat exchanger tube 2 of making of stainless steel seamless pipe is through in the installing hole of heat exchange fin 1, after all heat exchanger tube 2 is put on, through the mechanical expanding technology, with heat exchanger tube 2 with heat exchange fin 1 interference swelling, then according to the number of tube passes that designs, with connecting bend 3, the first distributing pipe 4, the second distributing pipe 6 corresponding and and heat exchanger tube 2 welding fabrications one by one.
The utility model will adopt heat exchange fin 1 to be sleeved on heat exchanger tube 2, then through the processing of mechanical expanding technology, make the outer wall of heat exchanger tube 2 with the heat exchange fin 1 tight Interference contact of installing hole inwall.Because the outer surface of heat exchange fin 1 scribbles the hydrophilic film corrosion-inhibiting coating, and the sheet type adopts corrugatedly, greatly improved heat transfer coefficient, antiseptic property; According to different medium flow velocity reasonable distribution number of tube passes, make the utility model can obtain better heat exchange efficiency, resistance is lower.
