Description
Technical field
The utility model belongs to energy and power engireering field, and in particular to a kind of cellular air cooled fin tube heat exchanger.
Background technology
A kind of structure type that air cooled fin tube uses when being and being exchanged heat between a kind of air and other heat transferring mediums.By
In air side surface film thermal conductance well below other heat transferring mediums in pipe surface film thermal conductance, so adding wing in air side
Piece is substantially shorter the length of heat-transfer pipe to reduce the volume and weight of heat exchanger.Usual finned tube exchanger is by heat exchange coil
It puts on whole fin to form through mechanical tension, as the main heat transfer form of air-cooled heat exchanger.The sky being widely used at present
Cold finned tube is：Pectination piece finned tube to enhance its heat transfer, is developed many new film types such as：Corrugated plate, windowing piece,
Point piece, quadric flanging etc., all have a certain upgrade effect.
For example, application publication number be CN106403689A Chinese invention patent application, disclose a kind of corrugated fin and
Air-conditioning heat exchanger is related to air-conditioning heat exchanger technical field, and the heat exchanger to solve existing air conditioner uses corrugated fin in name
The problem of heat exchange property is relatively low under volunteer's condition and invent.Corrugated fin of the present invention, including corrugated fin ontology, the corrugated fin
A plurality of hollow out item seam is offered on ontology.
In another example application publication number is the Chinese invention patent application of CN106370041A, a kind of air conditioner refrigerating is disclosed
The ripple slitted fin of technical field, including：Region, leeward region and it is arranged on two interregional several heat exchange areas under control windward
Domain, the heat exchanger tube region are evenly equipped with several heat exchanger tube mounting holes along longitudinal direction；The neighbouring heat exchanger tube mounting hole it
Between be arranged with several first bar shaped hollow outs along heat exchanger tube region axis face and stitch, the region windward and leeward region are arranged with
Several second bar shaped hollow out seams.
It is above-mentioned that the prior art is defective is：Because pectination piece is parallel with air-flow direction, to reduce noise,
In the air heat exchanger of forced convertion, the flowing velocity of air is typically limited to 2.0~2.5m/s.It is changed when air head-on flows to
During hot device, fin side is with the presence of the viscid layer, that is, boundary layer of certain thickness air, and the heat transfer of air is leaned on substantially in boundary layer
Conduction, and the thermal conductivity factor of air is very low, this is the root of finned tube heat-transfer capability difference, and many improvement of people are also from broken
Bad selvedge interlayer starts, and heat transfer efficiency highest can reach 35~45W/m2H DEG C, but because the structure of pectination piece limits,
Without much rooms for promotion.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of cellular air cooled fin tube heat exchange
Device.
The technical solution of the utility model is：A kind of cellular air cooled fin tube heat exchanger, the heat exchanger both sides are equipped with
Air panel is passed in and out, finned tube (not shown) is provided in the heat exchanger, finned tube is laminated using single row fin pipe structure
Arrangement, when needing several combs, it is that 1 piece is wide often to arrange the distance between finned tube, and the fin of finned tube is inclined ripple
Fin, is provided with pore on inclined corrugated fin, and the angle between the ripple of adjacent corrugated fin is 90 °, corrugated fin
Ripple and the angle of air-flow direction be 45 °~60 °, single row fin pipe combine to be formed it is cellular.
Further, the modes of emplacement of corrugated fin is symmetrically stacks in 90 ° of angle.
Further, the thickness of corrugated fin is 0.15~0.3mm.
Further, the distance of pore is 2.5 times of pore diameter.
The advantageous effect of cellular air cooled fin tube heat exchanger described in the utility model is：When air flows, it can rise
To souring, boundary layer is substantially not present, and by matching trial operation with unit, effect is ideal, has reached expected effect
Fruit.It is detected through authoritative department, the heat transfer efficiency of new finned tube has reached 80~100W/m2H DEG C, and the usage amount of aluminium foil reduces
Half.
