Abstract
The utility model relates to a finned heat exchanger for an air conditioner, which comprises more than two refrigerant pipes (1) and fins (2) which are closely sheathed on the refrigerant pipes (1). The utility model is characterized in that the diameters (D) of the refrigerant pipes (1) are 3.5-6mm; the center distance (S) between every adjacent two refrigerant pipes (1) in one row is 10.4-18mm; and the widths (B) of the fins (2) are 9-16mm. Compared with the prior art, the utility model has the characteristics of compact structure, small physical dimensions, low cost and the like, and can effectively enhance the heat exchange efficiency per unit volume.
Description
Technical field
The utility model is a kind of air-conditioner fin formula heat exchanger, belongs to the improvement technology of air-conditioner fin formula heat exchanger.
Background technology
Improving the heat exchange efficiency of air-condition heat exchanger and the cost of reduction heat exchanger is current air conditioner industry emphasis research topic, little caliber, miniaturization, compact conformation will be the developing direction of following air-conditioning, air-condition heat exchanger copper pipe external diameter is from 9.52mm, and then the exploitation and 7.94mm, 7mm, the 6.35mm of extensive use, and now just at 5mm, the 6mm of large-scale promotion with carried out the research of 4mm heat exchanger.But enforcement along with the new efficiency standard of China and various countries, there are the following problems for tradition tubule footpath heat exchanger technology: though the coefficient of heat transfer in the small caliber inner screw thread pipe pipe increases, but heat exchange area in the unit length pipe and pipe outside fin heat exchange area can't directly substitute big caliber heat exchanger all less than the heat exchanger of 7mm.For example, the centre-to-centre spacing of 5mm caliber heat exchanger is 19～21mm now, and sheet is wide to be 10～12mm, and the sheet type is bridge sheet or shutter, and owing to fin heat exchange area outside the pipe is less, the heat exchanger overall performance is not high when directly using as evaporimeter for this heat exchanger; Then need when using as window machine condenser more than at least two rows, it is main mostly being three rows in the practical application.When condenser three rows when above, the heat exchanger effect is poor after the 3rd row and the 3rd row, thereby causes whole heat exchanger cost performance not high.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and a kind of compact conformation is provided that appearance and size is little, can effectively improve heat exchange efficiency in the unit volume, the air-conditioner fin formula heat exchanger that cost is low.
The technical solution of the utility model is: a kind of air-conditioner fin formula heat exchanger, comprise that two above refrigerant pipes reach the fin that tightly is enclosed within on the refrigerant pipe, the caliber that it is characterized in that described refrigerant pipe is 3.5～6mm, with the centre-to-centre spacing between the adjacent refrigerant pipe of row is 10.4～18mm, and the width of fin is 9～16mm.
Above-mentioned refrigerant pipe is light pipe or riffled tube.
The form of cracking of above-mentioned fin is plain film, shutter, bridge sheet or corrugated plate.
The utility model compared with prior art its to have a beneficial effect fruit as follows: compact conformation, characteristics such as appearance and size is little, can effectively improve the unit volume heat exchange efficiency, and cost is low.
Description of drawings
Fig. 1 is the novel structural representation of this usefulness.
The specific embodiment
As shown in Figure 1, the utility model air-conditioner fin formula heat exchanger, comprise that two above refrigerant pipes 1 reach the fin 2 that tightly is enclosed within on the refrigerant pipe 1, the caliber D of described refrigerant pipe 1 is 3.5～6mm, with the centre-to-centre spacing S between the adjacent refrigerant pipe 1 of row is 10.4～18mm, the width B of fin 2 is 9～16mm, and spacing P is 9～20mm between the adjacent staggered refrigerant pipe 1.
Because with the centre-to-centre spacing S between the adjacent refrigerant pipe 1 of row is 10.4～18mm, with existing centre-to-centre spacing 19～21mm reducing by a relatively large margin arranged, increased unit length intraductal heat exchange area, the fin sheet is wide accordingly suitably adjusts, and makes it to be complementary with the intraductal heat exchange area.Simultaneously, in order to enhance productivity, the equipment that reduces bending machine and electric tube expander drops into expense, and preferred center is apart from S=P, in this example, the centre-to-centre spacing S=P=15.5mm between the refrigerant pipe, the width B of fin 2 is 13.42mm.
In the present embodiment, above-mentioned refrigerant pipe 1 is light pipe or riffled tube.The form of cracking of above-mentioned fin 2 is plain film, shutter, bridge sheet or corrugated plate.Because centre-to-centre spacing reduces with respect to former centre-to-centre spacing, air wide pre. drop increases, and preferably the form of cracking is the bridge sheet, and the bridge sheet that cracks is counted 2-6, and air side has the higher coefficient of heat transfer and the little characteristics of circulation of air resistance; For the outer machine condenser of split air conditioner, consider defrost, preferred W type or sinusoidal waveform fin.
Claims (3)
1. air-conditioner fin formula heat exchanger, comprise that two above refrigerant pipes (1) reach the fin (2) that tightly is enclosed within on the refrigerant pipe (1), the caliber (D) that it is characterized in that described refrigerant pipe (1) is 3.5～6mm, with the centre-to-centre spacing (S) between the adjacent refrigerant pipe of row (1) is 10.4～18mm, and the width (B) of fin (2) is 9～16mm.
2. air-conditioner fin formula heat exchanger according to claim 1 is characterized in that above-mentioned refrigerant pipe (1) is light pipe or riffled tube.
3. air-conditioner fin formula heat exchanger according to claim 1, the form of cracking that it is characterized in that above-mentioned fin (2) are plain film, shutter, bridge sheet or corrugated plate.
