Abstract
The invention discloses a heat exchange tube with a wavy fin. The heat exchange tube comprises a tube body and the fin. The fin is spirally arranged on the outer surface of the tube body. A plurality of grooves are arranged in the side face of the fin and connected sequentially into a wavy form. The outer end face of the fin is smaller than the inner end face of the fin. According to the heat exchange tube with the wavy fin provided by the scheme of the invention, the grooves are arranged in the side face of the fin and connected sequentially into the wavy form. Compared with the prior art, the outer surface area of the fin is increased, so that the heat exchange efficiency of the heat exchange tube is improved. The outer end face of the fin is smaller than the inner end face of the fin so that heat can be diffused to the periphery of a heat exchanger conveniently. The heat exchange efficiency of the scheme of the invention can be at least improved by 20%.
Description
Technical field
The present invention relates to a kind of improvement of heat exchange element of heat exchanger, especially a kind of heat exchange efficiency high with Wavelike finned heat exchanger tube.
Background technology
Heat exchanger tube is placed within the cylindrical shell of heat exchanger as one of element of heat exchanger, is used for the exchange of heat between two media, is widely used in the equipment such as air-conditioning.Usually, in order to improve heat exchange efficiency,, increase the external surface area of heat exchanger tube, thereby reach the purpose that improves heat exchange efficiency by with fin on the surface of heat exchanger tube.The cross section of the fin on the existing heat exchanger tube is take square as main, but the heat exchange efficiency of the heat exchanger tube of this structure is not high.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of heat exchange efficiency high with Wavelike finned heat exchanger tube.
For achieving the above object, the technical solution used in the present invention is: a kind of with Wavelike finned heat exchanger tube, comprise body, fin; Described fin helical form is arranged on the outer surface of body, and the side of described fin is provided with a plurality of grooves, and described a plurality of grooves link to each other successively and form waveform.
Preferably, the outer face of described fin is less than its inner face.
Preferably, the thickness of the outermost end of described fin is no less than 1mm.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The present invention program is described with Wavelike finned heat exchanger tube, the side of described fin is provided with a plurality of grooves, and described a plurality of grooves link to each other successively and form waveform, with respect to prior art, the external surface area of fin is increased, and gets heat exchange efficiency thereby improved heat exchanger tube; And the outer face of described fin is conducive to heat and distributes to the periphery of heat exchanger less than its inner face; The present invention program's heat exchange efficiency can improve 20% at least.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram with Wavelike finned heat exchanger tube of the present invention;
Accompanying drawing 2 is the described fin cross section enlarged drawing with Wavelike finned heat exchanger tube of band of the present invention;
Wherein: 1, body; 2, fin; 3, groove.
The specific embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1-2 is of the present invention a kind of with Wavelike finned heat exchanger tube, comprises body 1, fin 2; Described fin 2 helical forms are arranged on the outer surface of body 1, and the side of described fin 2 is provided with a plurality of grooves 3, and described a plurality of grooves 3 link to each other successively and form waveform; The outer face of described fin 2 is less than its inner face; The thickness of the outermost end of described fin 2 is no less than 1 mm, and in the present embodiment, the thickness of the outermost end of described fin 2 is 2mm, and the end of described fin 2 is not fragile.
The present invention program is described with Wavelike finned heat exchanger tube, the side of described fin is provided with a plurality of grooves, and described a plurality of grooves link to each other successively and form waveform, with respect to prior art, the external surface area of fin is increased, and gets heat exchange efficiency thereby improved heat exchanger tube; And the outer face of described fin is conducive to heat and distributes to the periphery of heat exchanger less than its inner face; The present invention program's heat exchange efficiency can improve 20% at least.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
