Abstract
The utility model discloses an internal and external tooth cooling tube comprising an outer tube whose center is provided with an inner tube. A tooth-shaped radiating fin is arranged between the inner tube and the outer tube. The tooth-shaped radiating fin is fixedly connected with the inner tube and is uniformly distributed around the periphery of the inner tube. The internal and external tooth cooling tube has the advantages of simple structure, safe use, good cooling effect, and high stability.
Description
Technical field
The utility model relates to the heat transmission equipment parts, is specifically related to a kind of inside and outside tooth cooling tube.
Background technology
At present, some machinery equipments of in many commercial production fields such as machinery, electric power, refrigeration, using all can produce heat in the process of running; Stable in order to guarantee that machine moves, just must use cooler, and the heat exchange effect of cooler depends on the heat exchange effectiveness of cooling tube; Common cooling tube is generally copper aluminium material matter, mono-tube design, and the heat exchange effect is general; And in a single day leakage point appear in single tube, can cause damage to the machine ability; In order to improve the heat exchange effect; Also being employed in the cooling tube outside rolls helicitic texture or manages outside suit heat radiating fin structure; The purpose of doing so mainly is to strengthen the heat-transfer effect of cooling tube lateral media, but such design can strengthen the volume of cooling tube, under the high pressure duty; Cooling tube stable bad, the difficulty of manufacturing and cost also can strengthen.
The utility model content
It is high that the purpose of the utility model provides a kind of heat exchange property, and stability is strong, safe and practical new and effective inside and outside tooth cooling tube.
The technical scheme of the utility model: a kind of inside and outside tooth cooling tube, comprise outer tube, outer tube hub is provided with interior pipe, is provided with the profile of tooth fin between the inner and outer pipes, between profile of tooth fin and the interior pipe is to be fixedly connected.
Said profile of tooth fin evenly distributes around interior pipe periphery.
Said profile of tooth fin is at least 10.
The technique effect of the utility model: the double layer design of inner and outer pipes, cooling medium flows at interior pipe, in case breakage appears in interior pipe, it is inner that cooling medium leaks the inflow outward appearance, avoided the damage to machinery equipment; The profile of tooth heat radiating fin structure is set between the inner and outer pipes, and the temperature of pipe is well passed through fin conductive to outward appearance in making, has quickened the heat exchange efficiency of cooling tube, and the utility model is simple in structure, and is safe in utilization, good cooling results, and stability is high.
Description of drawings
Fig. 1 is the longitudinal section cutaway view of the utility model.
Fig. 2 is the cross section view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of inside and outside tooth cooling tube comprises outer tube 1, pipe 2 in outer tube 1 center is provided with; Being provided with profile of tooth fin 3 between the inner and outer pipes, is integrated molding between profile of tooth fin 3 and the interior pipe 2, and said profile of tooth fin evenly distributes around interior pipe periphery; Said profile of tooth fin is 13, outward appearance diameter 10mm, diameter of inner pipe 5mm; The high 4mm of fin during use, goes into interior pipe box between the outer tube to get final product.
The cooling tube of the utility model can adopt material such as copper, aluminium, stainless steel; Through test; Its single phase flow heat transfer coefficient can reach 2.5-6 times of common light pipe cooling tube; Boiling heat transfer coefficient can reach 2-5 times of common light pipe cooling tube, and condensation heat transfer coefficient can reach 3-5 times of common light pipe cooling tube, and test data is following:
| Project/product | Inside and outside tooth cooling tube | Common light pipe cooling tube |
| Water-water | 1000-30000w/m2k | 400-5000w/m2k |
| Air-water | 500-900w/m2k | 120-160w/m2k |
| Gas-gas | 40-400w/m2k | 15-50w/m2k |
| Gas (in the pipe)-water boiling | 70-200w/m2k | 30-40w/m2k |
| Gas (pipe external chiasma-devaporation | 100-400w/m2k | 25-100w/m2k |
