Abstract
The utility model relates to a heat exchange tube with waved fins. The heat exchange tube with the waved fins comprises a tube body and the fins, wherein the fins are arranged on the outer surface of the tube body in a spiral mode, a plurality of grooves are formed in the side faces of the fins, the plurality of grooves are connected in sequence to form a wave shape, and the outer end face of each fin is smaller than the inner end face of each fin. Due to the fact that the plurality of grooves are formed in the side faces of the fins, and the plurality of grooves are connected in sequence to form the wave shape, the outer superficial area of the fins is increased compared with the prior art, and further heat exchanging efficiency of the heat exchange tube is improved. Furthermore, due to the fact that the outer end face of each fin is smaller than the inner end face of each fin, emission of heat to the periphery of a heat exchanger is benefited. According to the heat exchange tube with the waved fins, heat exchanging efficiency can be improved by at least 20%.
Description
Technical field
The utility model 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.
The utility model content
The utility model purpose be 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 adopted in the utility model 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 utility model compared with prior art has following advantages:
The utility model scheme 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 obtains increasing, 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 heat exchange efficiency of the utility model scheme can improve 20% at least.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the stereogram with Wavelike finned heat exchanger tube described in the utility model;
Wherein: 1, body; 2, fin; 3, groove.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1-2 is described in the utility model 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 utility model scheme 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 obtains increasing, 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 heat exchange efficiency of the utility model scheme can improve 20% at least.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
