Abstract

The utility model relates to a carry out endothermal needle type fin heat pipe at the heat pipe surface through increasing needle type fin, include: one is located the heat pipe body, diameter 4 -8mm's needle type fin in the surface parts welding outside the heat pipe body. Be filled with working medium in the tube. The needle type fin that the fin heat pipe is located the outer surface parts of body carrying out the bending through the crook with needle type fin, makes needle type fin heat pipe's volume littleer after welding the body. Needle type fin heat pipe can exert fine energy -conserving environmental protection profit in flue gas waste heat utilization field, have high using value.

Description

Needle type fin heat pipe

Technical field

The utility model relates to a kind of heat pipe, particularly relates to a kind of needle type fin heat pipe being undertaken absorbing heat by increasing needle type fin at heat pipe outer surface.

Background technology

In existing industrial furnace smoke discharge, flue gas takes away a large amount of heats, namely wastes the energy, pollutes environment again.In flue gas waste heat recovery heat exchanger, widely applied heat pipe, it is high that heat pipe has heat exchange efficiency, and every root heat pipe can independently conduct heat, the advantages such as long service life.

Heat pipe under prior art is for increasing heat exchange area, and major part adopts high frequency welding spiral fin tube, or nickel-based brazing spiral fin coil, and in the running of equipment, dust stratification appears in the dust in flue gas in helical fin, has a strong impact on the heat exchange property of equipment.

Now can increase heat pipe outer surface heat exchange area in the urgent need to one, again the heat pipe of not dust stratification, needle type fin heat pipe can effectively solve the problem.

Utility model content

The utility model object is to provide a kind of and improves heat pipe not dust stratification in flue gas running by changing heat pipe outer surface augmented form, improves the service life of heat exchange of heat pipe.Concrete structure of the present utility model is as described below:

Needle type fin heat pipe, comprising: one is positioned at tube body of heat pipe, the needle type fin of diameter 4-8mm in the welding of tube body of heat pipe outer surface part.

The needle type fin that described needle type fin heat pipe is positioned at body external portion arranges weekly 8-12 needle type fin.

Described needle type fin heat pipe is positioned at the needle type fin of outer surface of tube body part after being welded to body, is being bent by needle type fin by flector, makes the volume of needle type fin heat pipe less.

Needle type fin heat pipe of the present utility model is used to obtain following beneficial effect:

The utility model needle type fin heat pipe is welded on the surface of shell because of one end of each pin, and the other end can produce micro-quivering along with the flowing of flue gas in flue gas, a small amount of dust vibrations on needle type fin can be gone down.

The utility model needle type fin heat pipe because of each needle type fin be cylindrical, dust can get off by Automatic-falling above falling, thus ensure needle type fin heat pipe run in not dust stratification.

The utility model needle type fin heat pipe flue gas can contact with heat exchanger tube is horizontal or vertical, can not increase the running resistance of equipment.

The extended surface that the utility model needle type fin heat pipe structure is compact, lightweight, needle-tube is unique increases by 8 times than light pipe.

Detailed description of the invention

Below in conjunction with drawings and Examples, utility model needle type fin heat pipe is further described:

Embodiment

As shown in Figure 1 and Figure 2, the utility model needle type fin heat pipe has heat transfer medium 2 in body 1 inside, has needle type fin 3. in body 1 outside

Lower end first seals by the body 1 in the present embodiment, then is joined in body 1 by medium 2, and is sealed body 1 upper end.

The utility model needle type fin heat pipe is needle type fin 3 in the welding of the outside of body 1, and is bent with flector by needle type fin 3, to reduce the volume of needle type fin heat pipe.

The utility model needle type fin heat pipe utilizes in field can play good energy conservation and environmental protection benefit at fume afterheat, has high using value.

Claims

1. needle type fin heat pipe, comprising: one is positioned at tube body of heat pipe, the needle type fin of diameter 4-8mm in the welding of tube body of heat pipe outer surface part.

2. needle type fin heat pipe as claimed in claim 1 is characterized in that the needle type fin that described needle type fin heat pipe is positioned at body external portion arranges weekly 8-12 needle type fin.

3. needle type fin heat pipe as claimed in claim 1 is characterized in that described needle type fin heat pipe is positioned at the needle type fin of outer surface of tube body part after being welded to body, is being bent by needle type fin, make the volume of needle type fin heat pipe less by flector.
