Abstract
The utility model relates to a finned tube radiator, which is composed of a casing, finned tubes in the casing, and connecting boxes for connecting the finned tubes. The utility model is characterized in that finned tubes adopts finned tubes with U-shaped double coiled spiral structure fins, as the finned tubes are used, the contact area of each fin and a core pipe can be increased, the heat resistance is small, the heat exchanging efficiency is high, the production cost is reduced, and the work efficiency is improved.
Description
The utility model relates to a kind of heat exchanger, particularly a kind of finned tubular radiator.
Usually, adopt in the heating equipment by the radiator that finned tube constituted that is provided with in housing and the housing, during work, its heat is to distribute by the louvre of finned tube through housing top, and the general finned tube or embedded finned tube or the cold wound finned tube that are welded into for high frequency that adopts of finned tube, and their fin is the monolithic fin, because monolithic fin and core pipe contact-making surface are less, so have the low shortcoming of heat exchange and working (machining) efficiency, particularly adopt cold wound finned tube, though production cost is lower than the finned tube that ratio-frequency welding is connected into, because contact is bad, thermal property is poorer.
The purpose of this utility model is to provide a kind of finned tubular radiator, and it is the working (machining) efficiency height not only, and cost is low, and thermal property is good.
Its concrete solution is: the finned tube that is provided with in the housing adopts the finned tube with type double-spiral structure fin, so not only can increase the contact area of fin and core pipe, make thermal resistance little, the heat exchanger effectiveness height, and the connected mode that can adopt cheap resistance welded mode or mechanical compaction between core pipe and the fin realizes working (machining) efficiency height, the purpose that cost is low with this with fin is cold on the core pipe, two stiles of type fin can be contour or not contour two kinds of forms, to satisfy the designing requirement of external heat-exchanging media flow resistance.
The utility model adopts the finned tube with type double-spiral structure fin as main heat exchange elements, make that this fin tube type heat spreader structures is simple, production cost is low, adopt high frequency fin tube type radiator to compare with prior art, its equipment investment can reduce half, and production efficiency is enhanced about more than once, and the reduction of thermal resistance also makes it have the good heat transfer effect, and hot working efficiency is improved greatly.
In conjunction with the accompanying drawings the utility model is described in detail below by embodiment:
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure vertical view.
Fig. 3 is the A-A cutaway view of Fig. 1.
Fig. 4 is the fin tube structure schematic diagram.
Among Fig. 1, Fig. 2, Fig. 3, Fig. 4, side cover plate (7), upper cover plate (6) and header plate (4) are by rivet (3) the formation housing that is riveted together, the upper cover plate of housing (6) is provided with microscler louvre (5), is furnished with cold type double-spiral structure fin (9) on core pipe (8) in the housing and constitutes.
Under the duty, the finned tube of flowing through heating hydro-thermal amount can be distributed by fin (9), and through louvre heat is exported.
Claims (1)
1, a kind of finned tubular radiator, header box (2) by finned tube that is provided with in housing, the housing (1) and connection finned tube (1) constitutes, the top of housing is provided with louvre (5), it is characterized in that finned tube (1) is for having the finned tube of type double-spiral structure fin.
