Description

Water-cooled medium and small power IP55 generator

Technical Field

The invention belongs to the technical field of generator equipment, and particularly relates to a water-cooled medium and small power IP55 generator.

Background

The generator is mechanical equipment which converts other forms of energy into electric energy, is driven by a water turbine, a steam turbine, a diesel engine or other power machines, converts energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits the mechanical energy to the generator, and then the generator converts the mechanical energy into electric energy. The generator has wide application in industrial and agricultural production, national defense, science and technology and daily life. The generator has many forms, but the working principle is based on the law of electromagnetic induction and the law of electromagnetic force. The general principle of its construction is therefore: appropriate magnetic conductive and electric conductive materials are used to form a magnetic circuit and a circuit which mutually perform electromagnetic induction so as to generate electromagnetic power and achieve the purpose of energy conversion.

At present, most generators in use adopt air cooling heat dissipation, in order to promote air circulation, a generator shell needs to be opened, air heat dissipation is guaranteed, noise of the generator is greatly dissipated, good balance cannot be achieved between noise reduction and heat dissipation, and therefore the problems need to be solved through updated design.

Disclosure of Invention

The invention aims to provide a water-cooled medium-low power IP55 generator which is put into use to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a water-cooled medium and low power IP55 generator, includes generator sound insulation shell, the inside of generator sound insulation shell is provided with the holding cavity, the inboard of holding cavity is provided with fills the heat-conducting agent, and the inside of holding cavity is provided with the heat exchange tube, and the both ends of heat exchange tube respectively with two ring canal connections, be provided with the coupling on the ring canal, the inside welding of holding cavity has a plurality of copper sheets.

Preferably, the heat exchange tubes are spiral tubes and are uniformly distributed among the copper sheets.

Preferably, the copper sheet is made of brass, and a plurality of through holes are formed in the copper sheet.

Preferably, the side wall of the accommodating cavity is painted with anticorrosive paint.

Preferably, the outer side wall of the sound insulation shell of the generator is provided with a groove

The invention has the technical effects and advantages that: this medium and low power IP55 generator of water-cooled, the present case is the renewal design of going on generator housing, on guaranteeing to fall to make an uproar syllable-dividing basis, has guaranteed radiating quality, accomplishes to fall to make an uproar the balance between the heat dissipation, and the practicality is strong, job stabilization.

fig. 2 is a schematic structural view of the inside of the accommodating cavity.

In the figure: 1. a generator sound insulation housing; 2. an accommodating cavity; 3. a heat exchange pipe; 4. a ring pipe; 5. a pipe joint; 6. a copper sheet; 7. a through hole; 8. and (4) a groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a water-cooled medium and low power IP55 generator as shown in figure 1-2, which comprises a generator sound insulation shell 1, wherein a containing cavity 2 is arranged in the generator sound insulation shell 1, a heat conducting agent is filled in the containing cavity 2, a heat exchange tube 3 is arranged in the containing cavity 2, two ends of the heat exchange tube 3 are respectively connected with two ring tubes 4, a tube joint 5 is arranged on the ring tube 4, a plurality of copper sheets 6 are welded in the containing cavity 2 and rapidly transmitted to the generator sound insulation shell 1 after a stator winding of the generator generates heat, the generator sound insulation shell 1 transmits the heat to the heat conducting agent through the copper sheets 6, the heat conducting agent is heat conducting silicone grease, a water cooling pipe outside the tube joint 5 of the ring tube 4 is matched with the heat exchange tube 3 between the ring tubes 4 to form a passage, and the heat of the heat conducting agent is rapidly filled, the generator sound insulation shell 1 is continuously filled with heat conducting agent to realize heat dissipation, and the functions of sound insulation and noise reduction are realized by arranging a cavity and a closed space formed by a stator and a rotor.

The heat exchange tubes 3 are spiral tubes and are uniformly distributed among the copper sheets 6, so that the contact time between cooling water and a filled heat conducting agent is prolonged, and the heat exchange effect is ensured.

Copper sheet 6 is the brass material, and has seted up a plurality of through-hole 7 on the copper sheet 6, increases the area of contact between packing heat-conducting agent and the copper sheet 6 to the heat of copper sheet 6 can be quick to packing the heat-conducting agent transmission.

Anticorrosive paint is coated on the side wall of the accommodating cavity 2, so that the side wall of the generator sound insulation shell 1 is prevented from being corroded by filling a heat conducting agent, the service life is prolonged, and the use safety is ensured.

The lateral wall of generator sound insulation shell 1 is seted up flutedly 8, guarantees the area of contact of generator sound insulation shell 1 and air, strengthens the self radiating effect of generator sound insulation shell 1.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
