Description

Heat exchange tube

Technical Field

The utility model relates to a heat transfer device, specifically speaking are heat exchange tubes.

Background

CN201320830624.7 discloses a heat exchange tube, which comprises a tube body and a plurality of fins located on the front and rear surfaces of the tube body, wherein the tube body and the plurality of fins are integrated into a whole. In order to increase the heat exchange efficiency of the heat exchange tube, the contact area between the heat exchange tube and the heat exchange medium on the outer side is increased, and the strength of the fin is increased, wherein the fin is in a water ripple shape or a zigzag shape.

However, the pipe body is a common square pipe body, the flow resistance of fluid in the pipe body is small, the flow speed is high, and the heat exchange effect with the pipe wall is poor.

Disclosure of Invention

The utility model aims at providing a can effectively increase heat transfer area, improve heat exchange efficiency's heat exchange tube.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the heat exchange tube of the utility model comprises a tube body and a plurality of fins positioned on the outer surface of the tube body; the tube body is wavy, the fins and the tube body are integrated, the heights of the fins from the roots of the fins connected with the tube body to the outer ends of the fins are equal, and the outer end faces of the fins are wavy and consistent with the waves of the tube body.

In the heat exchange tube, the tube body is wavy, namely the cross section of the tube body is wavy, and the fins extend in the width direction of the tube body.

In the heat exchange tube, the fins extend in a zigzag manner in the width direction of the tube body.

In the heat exchange tube, at least one partition plate is arranged in the cavity of the tube body, the partition plate is arranged along the length direction of the tube body, and the cavity of the tube body is divided into at least two flow channels by the partition plate.

In the heat exchange tube, the tube body is a flat tube, two side faces of the flat tube are wavy, and fins are arranged on the two side faces of the flat tube.

The utility model has the advantages that: because the pipe body is in the wave shape, the flowing resistance of fluid in the pipe body is large, the flowing speed is low, heat exchange can be carried out with the pipe wall more fully, and meanwhile, the heat exchange area is increased by the wave-shaped pipe body, so that the heat exchange efficiency is higher.

The tube body and the fins are integrated, the heights of the fins from the roots of the fins connected with the tube body to the outer ends of the fins are equal, and the outer end faces of the fins are wavy and consistent with the waves of the tube body. The heat exchanger with the structure can obtain an integral heat exchanger blank by adopting forming processes such as extrusion, drawing and the like, and then metal cutting processing is carried out on the heat exchanger blank to form fins on the outer surface of the tube body. The height of each part of the fin is equal, and the outer end face of the fin is in a wave shape consistent with the wave shape of the tube body, so that metal cutting processing is more convenient.

Drawings

FIG. 1 is a schematic structural view of a heat exchange tube of the present invention;

fig. 2 is a side view of fig. 1.

Detailed Description

Referring to the heat exchange tubes shown in fig. 1 and 2, the tube body 1 is a flat tube extending along the length direction, and the upper side surface and the lower side surface of the cross section of the flat tube are wavy. All set up a plurality of fins 2 as an organic whole with flat pipe on the flat pipe both sides face.

The fins extend in a zigzag manner in the width direction of the tube body.

The fins are of equal height from the roots of the fins connected to the tube body to the outer ends of the fins, and the outer end surfaces 21 of the fins are of a wave shape conforming to the wave shape of the tube body.

At least one partition plate 3 is arranged in the cavity of the pipe body and arranged along the length direction of the pipe body, and the cavity of the pipe body is divided into at least two flow channels by the partition plate.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention still belong to the protection scope of the technical solution of the present invention.
