Abstract

The utility model discloses a finned-tube heat exchanger, which comprises a finned-tube heat exchanger core, wherein the finned-tube heat exchanger core has an open round structure and the round end face of the finned-tube heat exchanger core faces an air hole of an axial flow fan; fins of the finned-tube heat exchanger core are the single-row hole fins; and the finned-tube heat exchanger core with the open round structure is constituted of multiple layers of finned tubes. The finned-tube heat exchanger in the utility model has the prominent advantages that volume is small, thermal efficiency is high and energy sources are saved.

Description

A kind of fin-tube heat exchanger
Technical field:
The utility model relates to heat transfer technology, particularly a kind of fin-tube heat exchanger.
Background technology:
The condenser of domestic air conditioner generally all adopts fin string pipe heat exchanger core body, and blower fan adopts axial fan, for the volume that makes condenser core reduces, saves space, adopts L-type or U-shaped structural shape more.The shortcoming that this structure exists is that the air-flow of axial-flow type aircraft is inhomogeneous, causes heat transfer coefficient inhomogeneous, causes heat exchanger core body heat exchanger effectiveness lower, and it is more to consume electric energy.
Summary of the invention:
The purpose of this utility model is to provide a kind of fin-tube heat exchanger of a kind of heat exchange efficiency height and good energy-conserving effect.
The technical scheme that realizes the utility model object is, a kind of fin-tube heat exchanger, comprise fin-tube heat exchanger core body, it is characterized in that: described fin-tube heat exchanger core body is opening circular configuration, and the circular end surface of this fin-tube heat exchanger core body is relative with the air port of axial fan.The fin of described fin-tube heat exchanger core body is single row of holes fin.The circular fin-tube heat exchanger core body of institute's opening is multilayer finned tube.
The utility model has the remarkable advantage that volume is little, the thermal efficiency is high and save the energy compared with the prior art.
Brief description of the drawings:
Fig. 1 is front view of the present utility model, and Fig. 2 is the A-A part section enlarged drawing of Fig. 1.
Detailed description of the invention:
The off-premises station (condenser) of domestic air conditioning is in order to reduce the appearance and size of condenser, generally the core body of condenser is made to L-type or U-shaped structure, because the round-shaped inconsistent heat exchanger fin causing of L-type or U-shaped structure and blower fan conducts heat inhomogeneous, the defect that heat exchange efficiency is lower, the utility model adopts the heat exchanger core body of circular configuration, this circular core body is even with contacting of blower fan, and heat exchange efficiency is higher, and the volume of core body is less.Due to the two ends of heat exchange core body need to arrange end socket 3 and coolant media into and out of pipe joint 1,2, thereby above-mentioned circular heat exchanger core body can not be the circle of sealing, but the circle of opening, fin 4 can be single row of holes (referring to figure), this single row of holes fin is easier in the time of bending, also can be double-row hole fin, but difficulty relatively when bending.The opening Round fin 4 pipe heat exchanger core bodys 5 that Fig. 1 provides are made up of the circular fin-tube heat exchanger core bodys of four layers of opening, the number of plies number and the hole count of each fin how much determine according to heat exchanger size.When multilayer opening fin-tube heat exchanger core body bending forming, successively bend, then assemble, the curvature of each layer is identical, consider the pitch smaller of bending rear fin inner termination, and the spacing of external end head becomes large characteristic, the fin inner termination after bending should not be in contact with one another even crimp.
The circular finned heat exchanger core body of above-mentioned opening shape is identical with the axial fan of circular blade, thereby the wind of its each several part is more even, and heat exchange efficiency is higher, and its volume is less, and power of fan is less, saves material.Both can dry, also can exhausting, two kinds of forms can be optional.
