Description

A kind of shell and tube light pipe heat exchanger

Technical field

The utility model relates to heat-exchanger rig field more particularly to a kind of shell and tube light pipe heat exchangers.

Background technique

For heat exchanger as a kind of facility essential in people's daily life, its development prospect is wide.With life Horizontal continuous improvement, the requirement of people's heat exchanging device are also higher and higher.Current finned heat exchanger is generally stainless by more The fin composition that steel-pipe welding extends, in each own connector imported and exported each other in both ends, remaining pipe fitting is all by both ends Special-shaped connecting tube pipe fitting is joined end to end two-by-two by soldering processes, conspire to create a water-flowing path.

Finned heat exchanger has as following drawbacks:

One, there are tolerance in special-shaped connecting tube process, there are deviation, assembly for the Hard link for causing between any two-stage When be not easy to assemble, need live manual tension sometimes or be bent these special-shaped connecting tubes.

Two, the special-shaped connecting tube being brazed bears internal high pressure after being heated in use again, is easy cracking, leak occurs The case where.

Three, after finned heat exchanger fin absorbs heat, heat is taken away without enough refrigerants (water for flowing through pipeline), After heated for a long time, fin is easy to melt adhesion, leads to heat exchanger uneven heating, heat exchanger local dry burning, after burning out heat exchanger Leak.

Four, stress can be generated after pipe fitting is heated, the deformation for causing pipe fitting junction certain is used for multiple times, holds in use process Medium easily in leakage pipe, is cashed as leak or gas leakage.

Utility model content

In order to overcome at least one defect described in the above-mentioned prior art, the utility model provides a kind of shell and tube light pipe and changes Hot device.

The utility model is that technical solution used by solving the problems, such as it is:

A kind of shell and tube light pipe heat exchanger, including heat-exchanging tube bundle and the cylinder manifold that the heat-exchanging tube bundle both ends are arranged in；Institute The heat exchange tube layer that heat-exchanging tube bundle is parallel to each other by one layer or more is stated to form；The heat exchange that the heat exchange tube layer is set side by side by several Pipe composition, and heat exchanger tube passes through the collecting tray connection being arranged in the cylinder manifold, the confluence two-by-two in the heat exchange tube layer Slot is staggeredly arranged at intervals in cylinder manifold；Manifold port is additionally provided on the cylinder manifold.

Shell and tube light pipe heat exchanger provided by the utility model is compared with finned heat exchanger, and shell and tube light pipe heat exchanger is not With fin, therefore the spacing between heat exchanger tube and pipe is shortened, when solving finned heat exchanger close to fire row, the heat of fin Measure the defect that cannot be transmitted to heat exchanger tube in time and be easy to cause deformation；At the same time, it by setting cylinder manifold and collecting tray, allows Heat exchanger tube in heat exchange tube layer is also serially connected between any two, eliminates special piece interconnected between different pipes, significantly The problem of saving the cost of labor of installation, while also avoiding pipe fitting joint leak.

Specifically, the heat exchanger tube is stainless steel material, it can high temperature high voltage resistant.

Specifically, the manifold port is cold medium import or thermal medium outlet.

Further, further include heat exchange tube fixer, be evenly equipped with and the heat exchange tube diameter on the heat exchange tube fixer The through-hole to match, the both ends of the heat exchanger tube extend through the through-hole.

By the fixed heat exchanger tube of heat exchange tube fixer, it ensure that and be spaced uniformly between Guan Yuguan, prevent heat exchanger tube from heating When deformation generate stress, destroy the structure of entire shell and tube light pipe heat exchanger.

Further, the heat exchange tube fixer is between the cylinder manifold, and equal along heat exchanger tube pipeline axis direction It is even be provided with it is multiple.

Further, the heat exchange tube fixer is integrally formed.

Multiple equally distributed integrally formed heat exchange tube fixers are unlikely to deform when heated as a result, so as to more preferable Protect heat exchanger tube in ground.

In conclusion shell and tube light pipe heat exchanger provided by the utility model has the following technical effect that

1) by the way that collecting tray is arranged in cylinder manifold, the place connected before allowing using copper pipe also becomes directly to exchange heat now Place, the area of entire heat exchange increases.Heat exchange area increases under same volume, and evaporation capacity can be improved；

2) due to shell and tube light pipe heat exchanger be not present front stage connection special piece, save installation it is artificial at The problem of this also avoids pipe fitting joint leak simultaneously；

3) by the fixed heat exchanger tube of heat exchange tube fixer, it ensure that and be spaced uniformly between Guan Yuguan, prevent heat exchanger tube from adding Deformation generates stress when hot, destroys entire shell and tube light pipe heat exchanger structure.
