Abstract
The utility model discloses a composite immersed tube, which comprises an inner tube and an outer tube, wherein a gap exists between the inner tube and the outer tube, and the inner tube and the outer tube are hermetically connected onto at least one common end part. The composite immersed tube has the advantages of simple structure, convenience for installation and low cost, and the cooling effect is greatly optimized.
Description
Technical field
The utility model relates to a kind of compound pipe that soaks, and particularly relates to a kind of compound pipe that soaks that is applied to cooling water equipment.
Background technique
In the dynamoelectric equipment industry; Cooling system is an extremely important ring, concerns the safe operation and the working life of the electromechanical assembly that is cooled, and also is to be prone to the weak ring that is in out in the cold; Cooling system is at the cooling system of device for high-power power electronic, and corollary equipment more is very important.
In cooling water tank, the cooling water that water pump is lower with temperature pumps into heat exchanger, and cooling water absorbs heat in heat exchanger, and temperature raises, and flows back to cooling water tank then.
In a kind of mode; The intake pipe of heat exchanger is arranged on cooling water tank inside, and there is certain height in the water level of cooling water tank, because the characteristic of fluid; Water temperature in the cooling water tank also can be along with height of water level produces difference; Water level lower temperature is lower, and water level eminence temperature is higher, so usually the water inlet of water pipe is arranged on low water level water tank bottom just.Yet in this case, cold water is from water inlet makes progress process of flowing, and inevitably through the zone of too high water temperature, through transmission of heat, temperature raise before getting into heat exchanger, so, greatly reduced heat exchange efficiency.
In another kind of mode, the intake pipe of heat exchanger is arranged on the cooling water tank outside, has avoided cold water to form heat exchange through the zone of too high water temperature like this.But so the outside water pipe of cooling water tank will take up room, and influence the apparatus arrangement of cooling system; Simultaneously; Because intake pipe is arranged on the cooling water tank outside, have to intake pipe is incubated setting, as coating thermal insulating material; In order to avoid freeze winter, or under summer high-temperature, carry out heat exchange with ambient temperature.
Those skilled in the art is devoted to research and develop the low heat insulation water inlet technology scheme of a kind of cost.
The model utility content
The technical problem that the utility model will solve is in order to overcome in the existing technology, and the deficiency of cooling water inlet pipe effect of heat insulation difference provides a kind of NEW TYPE OF COMPOSITE to soak pipe.
The utility model solves above-mentioned technical problem through following technical proposals:
A kind of compound pipe that soaks, its characteristics are that the said compound pipe that soaks comprises interior pipe and outer tube, has the space between said interior pipe and the outer tube, and interior pipe and outer tube are tightly connected at least one common end.
Preferably, said interior pipe and outer tube are integrally formed.
Preferably, said interior pipe and outer tube independently are provided with, and interior pipe is arranged among the outer tube.
Preferably, said interior pipe and outer tube are plastic materials.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets related domain general knowledge promptly gets each preferred embodiment of the utility model.
The positive progressive effect of the utility model is: the utility model is simple in structure, and is easy for installation, and cost is very low, optimizes cooling effect greatly.
Description of drawings
Fig. 1 is according to the intake pipe schematic representation under specific embodiment of the utility model.
Fig. 2 is an I portion zoomed-in view shown in Figure 1.
Fig. 3 is an II portion zoomed-in view shown in Figure 1.
Embodiment
The embodiment of the utility model will describe with reference to accompanying drawing.In Figure of description, the element with similar structure or function will be used the components identical symbolic representation.Accompanying drawing for the ease of each embodiment of explanation the utility model, is not to carry out the explanation of exhaustive to the utility model just, neither the scope of the utility model be limited.
Fig. 1, Fig. 2 and Fig. 3 show the water pipe structure schematic representation under specific embodiment of the utility model jointly.In this embodiment, pipe 12 and outer tube 14 in water pipe 10 comprises.In pipe process respectively with outer tube, all be comparatively common plastic materials, like the PVC material etc., the external diameter of interior pipe 12 like this can be easily with interior pipe insertion outer tube less than the internal diameter of outer tube 14.
For the common lower end of interior pipe 12 and outer tube 14, need be with the gap sealing of two pipes, in case after in the composite pipe immersion water, water gets into the gap of two pipes, increases transmission of heat, reduces effect of heat insulation.In one embodiment, the external diameter of interior pipe 12 increases, and with the internal diameter interference fit of outer tube 14, thereby reaches sealing effect.In another embodiment, can directly seal the gap port, reach sealing effect equally by sealer.Those skilled in the art will appreciate that sealing means is varied, is mature technique comparatively in the industry, and any technological means that reaches sealing effect all can be brought use.
Whether for the common upper end of interior pipe 12 and outer tube 14, depending on the circumstances need seal.If the gap of common upper end does not contact with water, and does not have water vapor on every side, can reduce the requirement of sealing, even do not seal.
Like this, when water pump with cooling water when water tank upwards pumps into heat exchanger because heat-blocking action is played in the gap between interior pipe and the outer tube effectively, like this, the temperature difference was improved when cooling water carried out heat exchange, had improved the efficient of heat exchange greatly.
In another embodiment, when the length of composite water pipe more in short-term, can use mould that interior pipe and outer tube is integrally formed, like this with regard to the natural operation of having accomplished sealing.
Those skilled in the art will appreciate that this technology can not only be applied in the cooling water system of heater, also can be applied on the water inlet pipe fitting of all water cooling systems.
Though more than described the embodiment of the utility model, it will be understood by those of skill in the art that these only illustrate, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these mode of executions under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
