Description

Fluid heat exchange tube

technical field

The utility model relates to a heat exchange tube, in particular to a fluid heat exchange tube.

Background technique

A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions, and are widely used.

The traditional heat exchanger adopts multi-tube parallel connection and coil-based structure, which has the defects of complex structure, high cost and large space occupation, and the plate heat exchanger is not suitable for the specific environment of heat exchange while flowing. affect the use of heat exchangers.

Contents of the invention

The technical problem to be solved by the utility model is to provide a fluid heat exchange tube, which can realize heat exchange well.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a fluid heat exchange tube, including a tube body, a partition plate with a heat transfer function is arranged in the inner cavity of the tube body, and the partition plate and the tube body The wall of the cavity is sealed and connected, and the partition plate divides the inner cavity of the tube into two through cavities in the axial direction; each of the through cavities at both ends of the tube body is respectively connected with a fluid pipe interface.

In order to increase heat exchange efficiency, the plate surface of the partition is a curved surface, and the partition is made of a metal material with good heat transfer effect.

At least one reserved interface is provided on the tube body, and the reserved interface communicates with a through cavity in the tube body.

Further, a thermal insulation layer is laid on the outer surface of the pipe body.

The utility model adopts the fluid heat exchange tube designed by the above-mentioned technical scheme. Since a baffle with heat transfer function is arranged in the inner cavity of the tube body, the baffle is sealed and connected with the wall of the inner cavity of the tube, and the baffle connects the inner cavity of the tube along the axis. Divide into two through-cavities in the direction of the pipe body, and respectively set fluid pipe interfaces at the openings of each through-cavity at both ends of the pipe body. The hot fluid and the cold fluid flow through different inner cavities of the pipe body through their respective fluid pipes. Under the action of the partition with heat transfer function, the heat of the hot fluid is transferred to the cold fluid through the partition, so that the cold fluid is heated to realize better exchange of heat. The utility model has the advantages of simple structure, low manufacturing cost and good use effect.

Description of drawings

Fig. 1 shows a schematic structural view of the fluid heat exchange tube of the present invention.

Detailed ways

The fluid heat exchange tube of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, the fluid heat exchange tube of the present invention includes a tube body 3, and a partition 6 is arranged in the inner cavity of the tube body 3, and the partition 6 is sealed and connected with the inner cavity wall of the tube body 3, so that the partition 6 along the tube The axial direction of the body 3 divides the inner cavity of the tube body 3 into two through cavities, the through cavity 2 and the through cavity 7, and the separator 6 is made of a metal material with good heat transfer effect, such as copper, aluminum, white steel, iron, etc. . A fluid pipe interface 1 and a fluid pipe interface 4 are respectively connected at the mouths of the through chambers 2 at both ends of the pipe body 3. The fluid pipe interface 1 is used as an inlet for a fluid, and the fluid pipe interface 4 is used as an outlet for the same fluid. Similarly, a fluid pipe interface 9 and a fluid pipe interface 5 are respectively connected at the mouths of the through chambers 7 at both ends of the pipe body 3, the fluid pipe interface 9 is used as the entrance of another fluid, and the fluid pipe interface 5 is used as another fluid. export.

The utility model also sets the surface of the partition 6 as a curved surface to enhance the contact surface and contact time of the two fluids in the pipe body 3 and improve the heat exchange efficiency. At least one reserved interface 8 is provided on the tube body 3, and the reserved interface 8 communicates with one of the through-cavities in the tube body 3, and the reserved interface 8 is used to lead the fluid in the through-cavity through the pipeline or to the through-cavity. Introduce fluid. An insulating layer (not shown in the figure) is laid on the outer surface of the pipe body 3 to reduce the heat loss of the pipe body 3 .

When in use, the hot fluid source can be connected to the fluid pipe interface 1, the hot fluid flows out of the pipe body 3 from the fluid pipe interface 4, the cold fluid source is connected to the fluid pipe interface 9, and the cold fluid flows out of the pipe body 3 from the fluid pipe interface 5, During the flow of the cold and hot fluids in the pipe body 3, the heat of the hot fluid is transferred to the cold fluid through the partition plate 6, so that the temperature of the fluid flowing out of the fluid pipe interface 5 is raised, and the purpose of fluid heat exchange is achieved.
