Abstract

The utility model discloses a multi-internal pipe sleeve typed heat exchanger. The sleeve is internally provided with a plurality of internal pipes which are compositely distorted in spiral shape. The utility model has the advantages of good heat exchange efficiency, high heat exchange efficiency, large heat exchange flux, and can be made into large-power sleeve-typed heat exchangers.

Description

Pipe box pipe heat exchanger in many

Technical field:

The utility model relates to a kind of heat exchanger.

Background technology:

In the prior art, the double pipe heat exchanger that comprises tube-in-tube condenser, be field common devices such as refrigeration, chemical industry, thermal power, its effect is by cold fluid refrigerant vapor to be carried out carrying out between condensation or the cold fluid and hot fluid heat exchange, usually form the interior and outer fluid of walking variety classes or temperature respectively of pipe of the pipe of interior pipe by interior pipe and sleeve pipe.But existing double pipe heat exchanger, heat exchange efficiency are not high, and the flow of heat exchanging fluid is also less.

Summary of the invention:

The purpose of this utility model is to provide pipe box pipe heat exchanger in big many of a kind of heat exchange efficiency height, heat exchange flow.

Technical solution of the present utility model is:

A kind of many interior pipe box pipe heat exchangers, its feature: adorn pipe in many in the sleeve pipe, distortion is combined into helical form between the many interior pipes.

At the end of interior pipe dress separation orifice, the import and export pipe of pipe in the dress of the separation orifice outside.Sleeve pipe is connected with the import and export pipe of sleeve pipe.Interior pipe has 3～10.Interior pipe is bellows, the helical bellows of light pipe or the effect of tool augmentation of heat transfer.

The utility model adopts many comparable single thick interior pipes of carefully interior pipe to increase heat transfer area; The pipe one-piece auger has shortened the length of double-pipe condenser (heat exchanger) on the one hand in many, makes its volume compact more, has increased the disturbance to outer fluid in managing on the other hand, increases fluid flow, and plays the effect of enhanced heat exchange; Owing to adopted in many pipe one-piece auger structure, good effect of heat exchange, heat exchange efficiency height, heat exchange flow are big, can be made into high-power double pipe heat exchanger.

Description of drawings:

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the configuration diagram of an embodiment of the utility model.

Fig. 2 is the A-A view of Fig. 1.

The specific embodiment:

A kind of many in the pipe box pipe heat exchanger, adorn in the sleeve pipe 4 and manage 3 (interior pipe can have 3～10 or more) in many, in many between the pipe 3 distortion be combined into helical form.At the end of interior pipe 3 dress separation orifice 2, the import and export pipe 1,7 of pipe in the dress of separation orifice 2 outsides, sleeve pipe 4 is connected with the import and export pipe 6,8 of sleeve pipe, and interior pipe can be bellows, the helical bellows of light pipe or the effect of tool augmentation of heat transfer.Whole heat exchanger can be made circle, ellipse or other shapes.

The course of work of the present utility model is: one of heat exchanging fluid is entered and is managed 3 in the one-piece auger by the inlet pipeline separation orifice 2 of flowing through, another kind of heat exchanging fluid is entered by the inlet tube 6 of sleeve pipe, outlet 8 outflow heat exchangers are passed through in the gap 5 between the pipe 3 and sleeve pipe 4 in many of flowing through.
