Description

High-efficient shell and tube heat exchanger

Technical Field

The utility model relates to a heat energy engineering equipment technical field, in particular to high-efficient shell and tube heat exchanger.

Background

The heat pump is a device for transferring the heat energy of a low-level heat source to a high-level heat source, and is also a new energy technology which is concerned all over the world, the heat pump can obtain larger heat supply amount only by consuming a small amount of reverse circulation net work, and can effectively utilize the low-level heat energy which is difficult to apply to achieve the purpose of energy saving.

Disclosure of Invention

The utility model discloses a remedy prior art's defect, provide a high-efficient shell and tube heat exchanger that heat transfer volume is big.

The utility model discloses a realize through following technical scheme:

the utility model provides a high-efficient shell and tube heat exchanger, characterized by includes a barrel, upper and lower both ends are connected respectively to upper and lower head of barrel, the upper cover is equipped with into fluorine flange and goes out the water flange, the low head is equipped with out fluorine flange and the flange of intaking, it is equipped with into fluorine tube sheet in the fluorine flange to advance, it is equipped with out fluorine tube sheet to go out the fluorine flange, be equipped with the tube bank of compriseing a plurality of copper pipes in the barrel, the both ends of tube bank are fixed respectively on advancing fluorine tube sheet and going out fluorine tube sheet

Flanges are welded at the upper end and the lower end of the cylinder respectively and are connected with the upper seal head and the lower seal head through the flanges respectively.

The inner wall of the copper pipe is an internal thread, and the outer wall of the copper pipe is a trapezoidal thread.

The utility model has the advantages that:

the utility model can adopt copper pipes with thinner inner diameter to carry out inner and outer finned treatment, and then the copper pipes are integrated into a pipe bundle through the pipe plates, so that gaseous refrigerant enters into the fluorine inlet flange and then is separated by the fluorine inlet pipe plates to enter into each copper pipe, and the copper pipes are wound in the cylinder body to be more favorable for water flow scouring; the inner wall and the outer wall of the copper pipe are respectively provided with the threads and the trapezoidal threads, so that the heat dissipation area is increased, and the heat exchange efficiency is improved. The utility model discloses heat exchange efficiency is high, and is small, difficult scale deposit to simple to operate does not account for the space.

Drawings

The invention will be further described with reference to the accompanying drawings:

FIG. 1 is a schematic sectional view of the present invention;

FIG. 2 is a schematic longitudinal sectional view of a copper pipe;

fig. 3 is a schematic sectional view taken along the direction a-a in fig. 1.

In the figure, 1 cylinder, 2 flanges, 3 upper end sockets, 31 fluorine inlet flanges, 32 water outlet flanges, 4 lower end sockets, 41 fluorine outlet flanges, 42 water inlet flanges, 5 fluorine inlet pipe plates, 6 fluorine outlet pipe plates, 7 copper pipes, 71 internal threads and 72 trapezoidal threads.

Detailed Description

The attached drawings are specific embodiments of the invention. As shown in fig. 1 to 3, the high-efficiency shell-and-tube heat exchanger comprises a cylinder 1, wherein flanges 2 are welded at the upper end and the lower end of the cylinder 1 respectively, the flange 2 at the upper end is connected with an upper end enclosure 3, the flange 2 at the lower end is connected with a lower end enclosure 4, and the upper end enclosure 3 is provided with two flanges: the fluorine inlet flange 31 and the water outlet flange 32 are arranged on the lower end socket 4, and the two flanges are arranged on the lower end socket: the fluorine inlet flange 31 is internally provided with a fluorine inlet tube plate 5, the fluorine outlet flange 41 is internally provided with a fluorine outlet tube plate 6, the fluorine inlet tube plate 5 and the fluorine outlet tube plate 6 are respectively provided with holes with the same number, the fluorine inlet tube plate 5 and the fluorine outlet tube plate 6 play a role in shunting fluorine gas, the cylinder 1 is internally provided with a tube bundle consisting of a plurality of copper tubes 7, two ends of each copper tube 7 are respectively fixed on the holes of the fluorine inlet tube plate 5 and the fluorine outlet tube plate 6, and the copper tubes 7 are designed in a surrounding way in the cylinder 1.

In order to increase the heat exchange area and improve the heat exchange efficiency, the inner wall of the copper pipe 7 is designed into an internal thread 71, and the outer wall of the copper pipe 7 is designed into a trapezoidal thread 72. The copper pipe 7 has high heat exchange coefficient, the coolant in the copper pipe 7 has good disturbance, and the heat exchange is sufficient.

Gaseous refrigerant enters through a fluorine inlet flange 31 on the upper end enclosure, is distributed through a fluorine inlet tube plate 5, and then fluorine gas uniformly enters each copper tube 7 and flows in the copper tube 7, releases heat into the cylinder 1 to realize the process of converting the gaseous state into the liquid state, and then flows out of a fluorine outlet flange 41 on the lower end enclosure 4; cold water flows in from the water inlet flange 42 of the lower end enclosure 4 (when water is fed, a circulating water pump is connected, which is the prior art), flows in the cylinder 1 from bottom to top, fully absorbs heat released by the multiple copper pipes 7, and flows out from the water outlet flange 32 of the upper end enclosure 3 after the heat is changed into high-temperature hot water.

Other technical features than those described in the specification are known to those skilled in the art.
