Description

Evaporating pipe with multiple heat exchange points

Technical Field

The utility model relates to an evaporation heat exchange tube, in particular to an evaporation tube with multiple heat exchange points.

Background

Evaporative heat exchangers are indispensable components in refrigeration systems. Among them, the evaporation tube is the most important component in the evaporation heat exchanger. The heat absorption by evaporation is to liquefy and absorb heat of the refrigerant in the tube body to form refrigeration, and the heat release by liquefaction and evaporation is realized in the reverse heating process. Therefore, in the using process, the heat exchange area of the evaporation heat exchange tube needs to be increased, and the evaporation heat exchange effect is ensured. The conventional mode is that the fin is arranged on the outer wall of the tube body and used for increasing the heat exchange area, however, the conventional radiating fin is easy to damage, and the fin with a large area is inconvenient to process and high in processing cost.

Disclosure of Invention

The utility model aims to provide a multi-heat-exchange-point evaporation tube, and by using the structure, the evaporation heat exchange effect is improved, and the processing cost is reduced.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a many heat transfer points evaporating pipe, includes the body, be equipped with outside helicla flute on the outer wall of body, outside helicla flute clockwise spiral set up in on the outer wall of body, it is equipped with multiunit heat dissipation bump still to separate on the outer wall of body, the multiunit heat dissipation bump sets up in adjacent between the outside helicla flute.

In the above technical scheme, the heat dissipation salient points are triangular pyramid structures or rectangular pyramid structures.

In the technical scheme, the protruding height of the heat dissipation salient point is 1/10-1/3 of the wall thickness of the tube body.

In the technical scheme, the inner wall of the pipe body is provided with the inner spiral groove, and the inner spiral groove is spirally arranged on the inner wall of the pipe body anticlockwise.

In the above technical scheme, the cross section of the internal spiral groove is in a semicircular arc structure.

In the above technical solution, a distance between adjacent outer helical grooves is equal to a distance between adjacent inner helical grooves.

Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

1. according to the utility model, the external spiral groove and the heat dissipation salient points are arranged, so that the heat exchange area can be increased, the heat exchange effect is improved, and the processing are convenient, and the cost is low;

2. according to the utility model, the inner spiral groove and the outer spiral groove are arranged in a reverse direction, so that the strength of the tank body is ensured, the heat exchange area can be increased, and the heat exchange effect is improved.

Drawings

Fig. 1 is a schematic structural diagram in a first embodiment of the present invention.

Wherein: 1. a pipe body; 2. an outer helical groove; 3. heat dissipation salient points; 4. an inner helical groove.

Detailed Description

The utility model is further described with reference to the following figures and examples:

the first embodiment is as follows: referring to fig. 1, the evaporating tube with multiple heat exchange points comprises a tube body 1, wherein an external spiral groove 2 is formed in the outer wall of the tube body, the external spiral groove is spirally formed in the outer wall of the tube body clockwise, multiple groups of heat dissipation salient points 3 are further arranged on the outer wall of the tube body at intervals, and the multiple groups of heat dissipation salient points are arranged between adjacent external spiral grooves.

In this embodiment, through set up the heat dissipation bump on the body outer wall, can increase body and outside heat transfer area as far as like this, improve the heat transfer effect, and simultaneously, set up outside helicla flute, also can increase heat transfer area, and set up the heat dissipation bump on the body outer wall between adjacent outside helicla flute, further heat transfer effect heat dissipation above the basis of outside helicla flute heat transfer can be so, and, the setting of outside helicla flute, the flow of the outside air medium of being convenient for, play the water conservancy diversion effect, improve the heat transfer effect, and when utilizing outside helicla flute water conservancy diversion heat transfer, the air medium that flows from outside helicla flute can flow into between the adjacent heat dissipation bump, be used for increasing heat exchange efficiency and effect.

Referring to fig. 1, the heat dissipation bump has a triangular pyramid structure or a rectangular pyramid structure. The polygonal cone is convenient to process, the contact area of the polygonal cone with an external air medium is increased, and the heat exchange effect is improved.

The protruding height of the heat dissipation salient points is 1/10-1/3 of the wall thickness of the tube body.

Referring to fig. 1, an inner spiral groove 4 is formed in the inner wall of the pipe body, and the inner spiral groove is spirally formed in the inner wall of the pipe body in a counterclockwise direction.

In this embodiment, the setting of inside helicla flute can play the effect of a direction, water conservancy diversion to the flow of inside flowing medium, can make the medium at the inside helical motion of body, and the area of contact and the contact volume of unit interval of further increase inside medium and body inner wall can improve heat transfer effect.

The section of the internal spiral groove is of a semicircular arc-shaped structure.

In this embodiment, the distance between adjacent outer helical flutes is equal to the distance between adjacent inner helical flutes. And outside helicla flute can misplace the setting with inside helicla flute each other, when inside and outside medium flows, has a plurality of cross positions like this, improvement heat exchange efficiency and effect that can be abundant.
