Abstract
The utility model relates to a finned pipe used in heat-exchange equipment, specifically to a cooling pipe with corrugated inner fins, comprising a heat transfer pipe and an inner pipe arranged inside the heat transfer pipe. Corrugated fins are brazed on the inner wall of the heat transfer pipe, and the inlet end plug of the inner pipe is flat head-shaped, R-shaped or parabolic-shaped. Compared with the prior art, the cooling pipe with corrugated inner fins provided in the utility model has the advantages of reasonable design, simple structure, long service life, low production cost, low fluid contact thermal resistance, high heat-transfer capability, etc.
Description
Technical field
The utility model relates to the finned tube that uses on a kind of heat transmission equipment, and a kind of ripple inner fin cooling tube specifically is provided.
Background technology
Usually, use on the heat transmission equipment, generally be the outer mode that adopts with fin of pipe, to increase heat exchange area, the weak point of this heat exchanger is that although strengthened the heat exchange area of gas side, the flow velocity of gas still remains at low levels, thereby total heat transfer coefficient is very low, thereby causes exchange capability of heat still not high.This class heat exchanger adopts the mode that increases volume to improve the heat exchange effect, and production cost also increases greatly.
Other has a kind of heat exchanger to adopt the zigzag heat exchanger fin, its heat exchange effect can but flow resistance increase, also because the restriction of inner fin structure, it only limits to common heat exchanger.
Summary of the invention
The utility model is at above deficiency, and a kind of reasonable in design, simple in structure, long service life, cost of manufacture is low, the fluid thermal contact resistance is little, heat-transfer capability is strong ripple inner fin cooling tube are provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of ripple inner fin cooling tube comprises heat-transfer pipe and interior pipe, is provided with interior pipe in the heat-transfer pipe, and soldering has corrugated fin on the inwall of described heat-transfer pipe, and described interior pipe import plug place adopts tack, R shape or parabola shaped structure.
Wing heat exchanger tube in the ripple of the present utility model, by heat-transfer pipe, interior pipe and be arranged on heat-transfer pipe and interior pipe between corrugated fin constitute, the wing item of corrugated fin is soldering with the inwall of heat-transfer pipe and is connected, so that corrugated fin and heat-transfer pipe really constitute integral body, interior pipe import plug adopts tack, R shape, parabola shaped structure, has reduced fluid contact flow resistance.
The wing heat exchanger tube has that flow resistance is little in the ripple of the present utility model, high efficient heat exchanging, making charge air cooler volume is little, overall structure simple, reduce manufacture cost and other advantages.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural front view of ripple inner fin cooling tube;
Fig. 2 is that A-A among Fig. 1 is to the cross section structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
A kind of ripple inner fin cooling tube comprises heat-transfer pipe 1 and interior pipe 2, pipe 2 in being provided with in the heat-transfer pipe 1, and soldering has corrugated fin 3 on the inwall of described heat-transfer pipe 1, and described interior pipe 2 import plugs 4 places adopt tack, R shape or parabola shaped structure.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
