Abstract
The utility model discloses a high-pressure coiled tubular heat exchanger center cylinder reinforcing devicewhich comprises a center cylinder (2), a heat exchange tube (4) wound on the center cylinder (2), and a filler strip (3) arranged between the center cylinder (2) and the heat exchange tube (4), wherein reinforcing and supporting ribs (1) are arranged on an inner wall of the center cylinder (2). The reinforcing and supporting ribs and the center cylinder are welded into a whole, the moment of inertia of the cross section of the center cylinder and the flexural modulus of the center cylinder are greatly improved, the deflection of the center cylinder is effectively reduced, the maximum normal stress of the center cylinder is reduced, and a mechanical model of the center cylinder is greatly improved. When the equipment is large, the thickness of the center cylinder can be greatly reduced under the condition that the length and weight of the heat exchanger are greatly improved, the material purchase difficulty and equipment manufacturing difficulty are reduced, the materials are greatly saved, and the product cost is reduced.
Description
Technical field
The utility model relates to a kind of intensity reinforcing device that uses at heat transmission equipment, particularly a kind of high voltage winding pipe heat exchanger central tube intensity reinforcing device.
Background technology
The high voltage winding heat exchange of heat pipe mainly by forming around tube core body and housing two parts, mainly is comprised of tube sheet, central tube, heat exchanger tube, filler strip and clip, wrapping cylinder etc. around the tube core body.Heat exchanger tube closely is wrapped on the central tube with certain coiling angle, between the heat exchanger tube and the separating with flat strip and special-shaped filler strip between layers of coiling, guarantee the horizontal and vertical spacing between the heat exchanger tube, be fixedly connected with clip between filler strip and the heat exchanger tube, central tube plays a supportive role when assembling.Because the maximization of domestic project, heat transmission equipment is also done larger and larger, length and weight around the tube core body all improve greatly, the high voltage winding heat exchange of heat pipe is in manufacture process, central tube is because amount of deflection is excessive, and is whole serious around the sinking of tube core body, the central tube insufficient strength, cause coiling to arrive last central tube fracture, equipment scrapping.Satisfy the intensity of central tube when assembling, certainly will will greatly increase the thickness of central tube, increased material purchases difficulty and manufacture difficulty, greatly wasted material, increased product cost.
Therefore, provide a kind of thickness that need not to increase central tube, but simple in structure, easy to use, and can improve the composite bending modulus of central tube and reduce the maximum （normal） stress of central tube, high voltage winding pipe heat exchanger central tube stiffening device has become a good problem to study.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, it is a kind of simple in structure, easy to use that the utility model provides, can effectively reduce the amount of deflection of central tube during assembling, improve the composite bending modulus of central tube and the maximum （normal） stress of reduction central tube, improve the device of central tube intensity.
The technical solution of the utility model is achieved in that
High voltage winding pipe heat exchanger central tube stiffening device comprises central tube 2, and is wrapped in the outer heat exchanger tube 4 of central tube 2, and is arranged on the filler strip 3 between central tube 2 and the heat exchanger tube 4, is provided with reinforcement brace rod 1 at the inwall of central tube 2;
Described filler strip 3 comprises flat strip and special-shaped filler strip;
Described reinforcement brace rod 1 is evenly arranged in central tube 2 inside;
Be furnished with flat strip and special-shaped filler strip on described central tube 2 outer surfaces; Heat exchanger tube 4 is coiled on flat strip and the special-shaped filler strip with identical helical angle;
Offer groove according to the axial spacing of heat exchanger tube 4 on the described special-shaped filler strip, heat exchanger tube 4 is placed in the groove;
Described heat exchanger tube 4 is fixed on flat strip and the special-shaped filler strip by clip;
The described reinforcement brace rod 1 that is positioned at central tube 2 inside is arranged in central tube 2 inside with the even number pattern;
Described reinforcement brace rod 1 vertical elongated central tube 2 inside that are arranged in that are positioned at central tube 2 inside, length direction can be divided into some sections, then staggered being evenly arranged in the central tube 2.
Positive beneficial effect:The utility model will strengthen brace rod and central tube is welded as a whole, greatly improved the inertia distance of central tube cross section, composite bending modulus with central tube, effectively reduced the amount of deflection of central tube, reduced the maximum （normal） stress of central tube, improve greatly the stress model of central tube, improved the intensity of central tube.In the situation of equipment enlarging, in the situation that heat exchanger length and weight all improve greatly, adopt the utility model can greatly reduce the thickness of central tube, reduce material purchases difficulty and device fabrication difficulty, greatly saved material, reduced product cost.
