Abstract

The utility model relates to an energy-saving radiating tube of a heat exchanger. The energy-saving radiating tube of the heat exchanger comprises an outer tube, an inner tube, air holes and a ring-shaped end plate, wherein the outer tube is of a cylindrical structure with the two open ends, the inner tube is of a cylindrical structure with one open end, the inner tube is installed in the outer tube in a coaxial and sleeved mode, a plurality of air holes are evenly distributed in the side wall of the inner tube in a spaced mode, and the ring-shaped end plate which is fixedly connected with the outer tube is fixedly installed on the periphery of the open end of the inner tube. The energy-saving radiating tube of the heat exchanger is simple in structure, and due to the facts that the inner tube with the air through holes is fixedly installed in the outer tube in the coaxial mode, and a plurality of axial pressing marks are manufactured on the outer tube, the heat transfer area between the inner tube and the outer tube is increased, the velocity of fluid in the inner tube and the velocity of fluid in the outer tube can be adjusted, heat transfer can be facilitated, and the effect of heat exchange is good.

Description

The energy-saving heat exchanger radiating tube

Technical field

The utility model belongs to heat exchange, heat dissipation technology field, especially a kind of energy-saving heat exchanger radiating tube.

Background technology

Heat exchanger is one of visual plant in the chemical enterprise, aborning, need to adapt to hyperbaric environment, quick heat loss through conduction, the primary structure of array pipe heat exchanger is to adopt array to be intervally arranged radiating tube to be installed on the tube sheet now, and radiating tube adopts common metal straight pipe, and tube wall area is less, and can not regulate internal gas flow speed, heat transfer effect is undesirable.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of simple in structure, design science, processing ease, high-efficiency environment friendly are provided.

The utility model solves its technical problem and takes following technical scheme to realize:

A kind of energy-saving heat exchanger radiating tube is characterized in that: comprise outer tube, inner tube, passage and annular endplate, outer tube is the penetrating cylinder barrel shaped structures in two ends, and inner tube is the cylinder barrel shaped structure of an end opening; Coaxial sleeve is equipped with an inner tube in the outer tube, and the sidewall spacers of this inner tube is uniform to be shaped with a plurality of passages, and an end periphery of interior tube opening is fixed with the annular endplate affixed with outer tube.

And an end of described interior channel closure is fixed with a mounting rod that radially is fixedly mounted with within the outer tube.

And, state the outer tube radial equipartition and be shaped with many axial impressions.

Advantage of the present utility model and good effect are:

Radiating tube of the present utility model, simple in structure, the inner coaxial inner tube that is shaped with through hole that is fixedly mounted with, outer tube is shaped with many axial impressions, increases inside and outside heat transfer area, and inner and outer pipe can be adjusted the speed of internal flow, more is conducive to conduct heat good effect of heat exchange.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of energy-saving heat exchanger radiating tube comprises outer tube 1, inner tube 3, passage 5 and annular endplate 6, and outer tube is the penetrating cylinder barrel shaped structures in two ends, and inner tube is the cylinder barrel shaped structure of an end opening; Coaxial sleeve is equipped with an inner tube in the outer tube, horizontal, vertical a plurality of passages, the space between these a plurality of passages connection inner tubes and outer tube of being shaped with uniformly at intervals of the sidewall of this inner tube; One end periphery of interior tube opening is fixed with the annular endplate affixed with outer tube, and the axial two ends of outer tube are all than interior pipe range.

During work, the air-flow of waiting for heat exchange enters inner tube by opening one end of inner tube, enters gap between inner tube and the outer tube through passage made on the inner tube, and finally the other end by outer tube flows out.

In order to guarantee the axiality of inner tube, prevent from rocking, an end of interior channel closure is fixed with a mounting rod 4 that radially is fixedly mounted with within the outer tube.

In order to strengthen radiating effect, described outer tube middle part radial equipartition is shaped with many axial impressions 2, and the outer tube middle part radial equipartition of the present embodiment is shaped with six impressions, and as shown in Figure 4, outer tube section is pressed into plum blossom-shaped.

During installation, with the affixed Len req that reaches of the coaxial order of many radiating tubes.

Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
