Said front-seat refrigerant pipe and middle row's refrigerant pipe are light pipe or screwed pipe, and front-seat fin and middle row's fin are plain film, corrugated plate or louvered fin; Back row's refrigerant pipe is a screwed pipe, and back row's fin is a louvered fin; D1＜D2, d1＜d2.
Row's trepanning during row's refrigerant pipe is provided with in row's fin correspondence in said; In the caliber of row's refrigerant pipe equal the caliber D1 of front-seat refrigerant pipe, the width of middle row's fin equals the width d1 of front-seat fin, the distance of center circle of row's trepanning is from being L in adjacent two.
The design of the asymmetric finned tube exchanger of the utility model is to come balance and improve the whole exchange capability of heat of many row's two devices through the exchange capability of heat that the exchange capability of heat that weakens the windward side finned tube improves leeward side two devices; Optimize the performance parameter of two devices; Reach and not only can save cost but also can improve air-conditioning overall performance coefficient purpose; Can reduce the complete machine material cost again, thereby improve the cost performance of air-conditioning, improve competitiveness of product.It is simple and reasonable, be prone to processing, improve heat transfer rate, cost is low.
Description of drawings
Fig. 1 is the utility model one example structure sketch map.
Fig. 2 is another example structure sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
First embodiment
Referring to Fig. 1, asymmetric finned tube exchanger is two row's heat exchangers, and two row's refrigerant pipes reach and tightly are enclosed within the front and rear row fin on the front and rear row refrigerant pipe before and after comprising.The caliber D1 of front-seat refrigerant pipe is less than the caliber D2 of back row's refrigerant pipe; The width d1 of front-seat fin 1 is less than the width d2 of back row's fin 2.
D1 is 5mm-7mm, and D2 is 7mm-9.52mm, and d1 and d2 scope are 11mm-22mm.
Front-seat fin 1 corresponding front-seat refrigerant pipe is provided with front-seat trepanning 1.1, and row's fin 2 corresponding back row's refrigerant pipes in back are provided with back row's trepanning 2.1; Wherein, the distance of center circle between adjacent two front-seat trepannings 1.1 and the adjacent two back row's trepannings 2.1 is from being L.
