Abstract

The utility model discloses a screwed titanium heat exchanger, which comprises a pipe body composed of a screwed inner pipe made of titanium material, wherein an outer pipe is sleeved outside the inner pipe and is made of titanium or stainless-steel; and meanwhile, the pipe body is helicoidally wound. The heat exchanger has the advantages of high heat transmission efficiency, low probability of corrosion, low probability of scaling interior, strong stress compensation capacity and compact structure.

Description

Titanium screw thread heat exchanger

Technical field

The utility model relates to technical field of heat exchangers, especially relates to a kind of titanium screw thread heat exchanger.

Background technology

Heat exchanger is the common components of fluid heat transfer.Usually, it mostly is zinc-plated light pipe preparation.Its defective is: 1, heat transfer efficiency is low.2, be easy to corrosion.3, inside is easy to fouling.4, a little less than the stress compensation ability.5, take up room greatly.Therefore be necessary to be improved.

The utility model content

For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of titanium screw thread heat exchanger, it have heat transfer efficiency high, be difficult for that burn into inside is less scaling, the stress compensation ability strong, the characteristics of compact conformation.

To achieve these goals, the technical scheme that the utility model adopts is: titanium screw thread heat exchanger, comprise body, described body comprises the screw-shaped inner tube, this inner tube outer cover has outer tube, and this inner tube is titanium material preparation, and this outer tube is titanium material or stainless steel material preparation, simultaneously, this body is wound around in the shape of a spiral.

Described body inside is provided with support.

After adopting said structure, the advantage that compared to the prior art the utility model has is:

1, heat transfer efficiency is high.Because heat exchanger adopts the titanium screwed pipe, the pipe inner runner section continuously suddenlys change, even cause fluid in the situation that the very low high turbulence state that also is in all the time of flow velocity, be difficult to form laminar flow, the main thermal resistance of convection heat transfer' heat-transfer by convection is overcome effectively, the inside and outside heat transfer of pipe strengthened simultaneously, thereby heat transfer coefficient is very high, is generally 2～3 times of traditional light pipe heat exchanger.

2, not perishable.The titanium material has the characteristics such as acidproof, alkaline-resisting, can be applicable to the stronger liquid of corrosivity such as relatively poor water quality or seawater, acid, alkali.

3, inner less scaling.The high turbulence of runner inner fluid makes the particulate in fluid be difficult to deposit fouling, even there is a small amount of dirt to generate, also due to medium turbulent flow inside and outside pipe, tube wall is washed away strongly, and the good antiscale property ability is strong.In addition, exist the strain that produces because of inner tube and outer tube thermal (temperature difference) stress on screwed pipe, make the curvature generation micro-variations of the screwed pipe with elastic characteristic, thereby make heat exchanger have the ability of antiscale and scale removal.

4, the stress compensation ability is strong.Screwed pipe when the inner and outer tubes thermal (temperature difference) stress is larger, has the curvature generation micro-variations of the screwed pipe of elastic characteristic because of its planform characteristic, in order to compensation, elimination thermal stress, has prevented that effectively traditional heat exchanger is easily by phenomenons such as drawing cracks.

5, compact conformation.Because this heat transfer coefficient of heat exchanger is very high, required heat exchange area is little, and the wall thickness of screwed pipe is thinner, so this heat exchanger structure is compact, both little light again.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated:

Fig. 1 is the front view of embodiment of the present utility model;

Fig. 2 is the top view of Fig. 1.

In figure: 10, body, 11, inner tube, 12, outer tube; 20, support.

The specific embodiment

Embodiment, see illustrated in figures 1 and 2: titanium screw thread heat exchanger comprises body 10.In the utility model, this body 10 comprises screw-shaped inner tube 11.So-called screw-shaped inner tube 11, the inside and outside side that refers to the longitudinal section of this inner tube 11 all is wavy.These inner tube 11 outer cover have outer tube 12.And this inner tube 11 is the preparation of titanium material, and this outer tube 12 is titanium material or stainless steel material preparation.Simultaneously, this body 10 is wound around in the shape of a spiral.That is, this body 10 forms similar helical spring structure.Obviously, the further like this heat exchange efficiency that increased.

Optimize, this body 10 inside are provided with support 20.Certainly, the inside of this body 10, refer to its in the shape of a spiral after, this spiral helicine inside is not to refer to this inner tube 11 places.This support 20 is used for convenient the installation.

The above is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
