Description
Technical field
The utility model relates to field of air conditioning, is specifically the U-shaped heat exchanger of air-conditioning.
Background technology
The heat exchanger of the air-conditioning of prior art is generally adopt straight type heat exchanger, and namely fin adopts board-type fin, and heat exchanger tube is also straight tube or straight U pipe, and straight tube or straight U pipe swelling are in board-type fin.The ventilation shaft that this board-type heat exchanger is arranged on air-conditioning is interior and vertical with the air intake direction of ventilation shaft.The area of this board-type heat exchanger is limited to the sectional area of ventilation shaft, namely the area of this board-type heat exchanger can not exceed the area of section of ventilation shaft, not enough once this heat exchanger exchange capability of heat, exchange capability of heat can only be improved by the shunt of the caliber or adjustment heat exchanger tube of changing heat exchanger tube, as each heat exchanger tube is arranged more closely knit, by caliber expansion etc., but find in actual production process that the practice operability of adjusting pipe diameter and shunt is not strong, the restriction of concrete technology can be subject to and be difficult to carry out, the processing and manufacturing required precision of set pair elbow as overstocked in pipeline is very high, be difficult to mass production, and, also can increase material cost and cost of labor.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of effectively can improve exchange capability of heat and manufacture process U-shaped heat exchanger easily under not increasing ventilation shaft sectional area and not changing heat exchange tube diameter and prerequisite along separate routes.
Technical solution of the present utility model is, a kind of U-shaped heat exchanger with following structure is provided, it comprises fin and swelling many heat exchange U in fin manage, fin becomes the U-shaped structure be made up of the first vertical section, the first arc section, crosspiece, the second arc section, the second vertical section with the heat exchange U pipe Integral bending of fin inside, crosspiece is vertical with the air intake direction of ventilation shaft, and two vertical sections are parallel with the air intake direction of ventilation shaft.
After adopting above structure, the U-shaped heat exchanger of the utility model compared with prior art, has the following advantages:
After this U-shaped heat exchanger bending, crosspiece still coincide with ventilation shaft sectional area, bend out two vertical sections then significantly increase heat exchange area, therefore this heat exchanger is under the prerequisite not increasing ventilation shaft sectional area, effectively improve exchange capability of heat, and bending implementation Process is convenient, workable; Improve just because of exchange capability of heat conversely speaking, therefore can under the prerequisite ensureing its exchange capability of heat, that the size of the sectional area of ventilation shaft and whole air-conditioning is done is more a little bit smaller, in air-conditioning market competition day by day intensely, obtain advantage.
As improvement, the both sides of every sheet fin are provided with one block of side plate, be provided with row's heat exchange U in every sheet fin to manage, this row's heat exchange U manages the circular hole and the integrant heat exchanger fin of circular hole swelling of heat exchange U pipe and the circular hole of the first side plate, the long through-hole of fin and the second side plate that pass the circular hole of the first side plate, the long through-hole of fin and the second side plate successively, and it is convenient and reliable that this structure manufactures assembling process.
As preferably, it comprises polylith heat exchanger fin, this U-shaped heat exchanger also comprises connecting plate, polylith heat exchanger fin draw close side by side and polylith heat exchanger fin from inside to outside length successively increase progressively, second side plate of whole heat exchanger fin is mutually concordant, polylith heat exchanger fin Integral bending foldable type, the second side plate of whole heat exchanger fin and connecting plate are spirally connected fixing; Namely first monolithic heat exchanger fin expand tube makes that the heat exchange U in every sheet fin, this fin manages, two pieces of side plate swellings heat exchanger plates integrally of fin both sides, again polylith heat exchanger plates is drawn close side by side a unified bending and molding, like this, can be simplified the operation step, enhance productivity, and a unified bending can make the heat exchanger plates bending radian of each layer identical, ensures that each piece of heat exchanger plates fits tightly; And, second side plate of whole heat exchanger fin is mutually concordant, because the straight tube outlet of heat exchange U pipe is all positioned at the second side plate side, this side before bending first to it, it is also alignment after ensureing bending, be convenient to the straight tube outlet weld ell of later stage at each heat exchange U pipe of this side, make each heat exchange U pipe be welded into overall coil pipe; Finally, polylith heat exchanger fin from inside to outside length successively to increase progressively i.e. outer heat exchanger fin the longest, take second place in centre, internal layer heat exchanger fin is the shortest, and after being convenient to bending, the first side plate side is mutually concordant.
