Abstract
The invention relates to a pipe fin type heat exchanger which comprises a plurality of refrigerant pipes (1) and fins (2), wherein the fins (2) are tightly sleeved outside the refrigerant pipes (1). The fins (2) in the first row, which are sleeved on the refrigerant pipes (1) and positioned in the flow direction of a heat exchange medium, are flat, and the fins (2) in the other rows have slit; or the front parts of the fins (2) in the first row are flat, and the rear parts of the fins (2) in the first row and the fins (2) in the other rows have slit. The invention can greatly reduce the wind resistance of the front part of the heat exchanger, increase the heat exchange temperature difference of the rear part, and enhance the whole heat exchange effect of the heat exchanger. When the pipe fin type heat exchanger is adopted under the condition of operation in equal pump power, the heat exchange performance can be improved by 5 to 10 percent. The invention can be widely used for various air-conditioning condensers and evaporators.
Description
Technical field
The present invention is a kind of fin-tube type heat exchanger, belongs to the renovation technique of fin-tube type heat exchanger.
Background technology
In recent years, along with the fierceness of the competition in air-conditioning market and the raising of national standard, the energy-conservation requirement of air-conditioner more and more comes into one's own.Fin-tube type heat exchanger is a heat exchanger structure form the most frequently used in the air-conditioning, and the slitted fin form that traditional single row or multiple rows heat exchanger is adopted mainly contains window and bridge sheet, and the fin of the front and rear part pattern of cracking is identical, and windage is bigger.The heat exchange effect of this heat exchanger front portion is better relatively, but because rear portion velocity field and temperature field concertedness become worse and worse, makes that back row's heat exchange effect is relatively poor, and then make the heat exchange property of heat exchanger integral body not high relatively.Chinese patent application number is to disclose the fin-tube type heat exchanger of dredging the close structure in back before a kind of front and rear part bridge shape fin adopts in 03108079.0, Chinese patent application number is for disclosing the fin-tube type heat exchanger that a kind of bridge shape and window shape fin adopt front wide and rear narrow structure among the 200720054033.X, these structure heat exchangers can reduce the windage at heat exchanger front row, strengthen the heat exchange effect, but since will be on a large scale mold exchange more, in real exchanger is produced, be difficult to apply.
Summary of the invention
The objective of the invention is to consider the problems referred to above and a kind of windage that can reduce the heat exchanger front portion greatly is provided, increase the heat transfer temperature difference at rear portion, strengthen the fin-tube type heat exchanger of the whole heat exchange effect of heat exchanger.
Technical scheme of the present invention is: comprise some refrigerant pipes and tightly be enclosed within the outer fin of refrigerant pipe, the first row's fin that is nested with on the direction that flows on the refrigerant pipe, along heat transferring medium is a plain film, other row's fins are slitted fin, or the first half of first row's fin is plain film, and the first row rear portion of fin and other row's fins are slitted fin.
Above-mentioned slitted fin is the slitted fin of bridge sheet or window form.
Offer several cold-producing medium pores on the above-mentioned fin.
The cross sectional shape of above-mentioned refrigerant pipe is circular, oval, oblate or bent limit shape.
Above-mentioned fin is a monoblock type, or is combined by the single fin more than two or two.
Above-mentioned some refrigerant pipes and the fin that tightly is enclosed within outside the refrigerant pipe are arranged as the single row or multiple rows form.
The above-mentioned version that whenever arranges the seam fin is identical, and promptly the angle of inclination of window is identical, the width of bridge sheet or window, highly, number is all identical.
The caliber of above-mentioned many row's refrigerant pipes is identical, or the caliber of first row's refrigerant pipe is respectively arranged the caliber of refrigerant pipe less than its rear portion.
The present invention is owing to adopt the structure of the original many row's finned heat exchangers of maintenance constant, change the form of cracking of first row's fin or first row's fin first half into the plain film structure, can effectively reduce the windage at heat exchanger front row, increase back row's heat transfer temperature difference, strengthen the collaborative of flow regional temperature field and velocity field, strengthen the heat exchange effect at rear portion, and then promoted the whole heat exchange property of heat exchanger.Adopt fin-tube type heat exchanger of the present invention, waiting under the pump power operational circumstances, heat exchange property can improve 5%-10%, and the present invention can be widely used on various air-conditioner condensers, the evaporimeter.The present invention is that a kind of design is ingenious, function admirable, convenient and practical fin-tube type heat exchanger.
