Description

From generator casing of taking cooling

Technical Field

The utility model relates to a shell, in particular to a generator shell with cooling.

Background

At present, the cooling measures of the high-voltage power generation equipment adopt an external air-air cooler, the external installation is limited by the space of a site, the applicability is limited, nonstandard customization is usually required, the use cost of the power generation equipment is increased by matched equipment, and the later maintenance cost of the cooler is also increased.

Disclosure of Invention

The utility model provides the self-cooling generator shell which has a simple structure, does not need external equipment, directly adopts the cooling pipe to penetrate into the shell to directly cool the inside of the generator, and greatly reduces the use cost.

The technical scheme adopted by the utility model is as follows: the utility model provides a from generator casing of taking cooling, includes the casing, and the casing includes inner shell, shell and both sides end plate, and the inner shell is coaxial to be set up in the shell, its characterized in that: the inner shell is characterized in that a front air guide retainer ring and a rear air guide retainer ring are respectively arranged at two axial ends on the outer wall of the inner shell, an air inlet and an air return opening are respectively arranged at the upper part and the lower part of the inner shell between the front air guide retainer ring and the rear air guide retainer ring, gaps are reserved on the peripheries of the front air guide retainer ring and the rear air guide retainer ring on the inner wall of the outer shell, a plurality of cooling pipes axially penetrate through the front air guide retainer ring and the rear air guide retainer ring, the cooling pipes are connected with an air inlet cover at one end of the shell in a sharing mode, and the air inlet cover consists of an inner ring cover and an outer ring cover.

The cooling pipe is an aluminum pipe.

The cooling pipe is connected with the front and rear wind guiding rings and the end plates at the two sides of the shell in an expansion and connection mode.

The upper parts of the front and rear windshield guiding rings are provided with upper gaps with the inner wall of the upper part of the shell, and the lower parts of the front and rear windshield guiding rings are provided with lower gaps with the inner wall of the lower part of the shell.

The air inlet and the air return opening are staggered in the axial direction.

The utility model adopts the air inlet cover to inlet a plurality of cooling pipes to cool the hot air which is fed between the inner shell and the outer shell from the air inlet of the generator in the inner shell, and the cooled hot air passes through the upper clearance to the outer side cavities of the inner, outer front and rear wind guide rings and passes through the lower clearance, and then returns cold air to the generator in the inner shell from the air return port, thereby realizing the cooling and cooling of the inside of the generator, realizing the self-cooling of the inside by additionally arranging the cooling pipes on the shell, eliminating the external cooler device, saving the installation space of equipment, reducing the weight of the whole generator and reducing the manufacturing cost of equipment. The design is simple, the structure is simple and convenient, the later maintainability is good, and the design and manufacturing cost is effectively reduced.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

in the figure: the air conditioner comprises an inner shell 1, an air inlet 2, an air return opening 3, an outer shell 4, an end plate 5, an upper gap 6, a lower gap 7, a cooling pipe 8, an air inlet cover 9 and a wind guiding ring 10.

Detailed Description

Further description is provided below with reference to the accompanying drawings.

Fig. 1 shows: the utility model provides a from generator shell of taking cooling, its casing includes inner shell 1, shell 4 and both sides end plate 5, inner shell 1 coaxial set up in outer shell 4 and both ends encapsulate through end plate 5, the axial both ends set up respectively preceding, two back wind-guiding collars 10 on the inner shell 1 outer wall, the air intake 2 that axial dislocation is seted up respectively to the upper and lower part of inner shell 1 between preceding, two back wind-guiding collars 10, return air inlet 3, upper gap 6 is left with the outer shell upper inner wall to preceding, two back wind-guiding collars upper end, lower gap 7 is left with the outer shell lower inner wall to preceding, two back wind-guiding collars lower extreme, a plurality of aluminum pipe cooling tubes 8 of axial expansion cross-under on the preceding, a plurality of cooling tubes connect the air inlet cover 9 of casing one end altogether.

In this embodiment, the air inlet cover is composed of an inner ring cover and an outer ring cover, and the inner ring cover and the outer ring cover are correspondingly connected with the inner shell and the outer shell outwards.

In the embodiment, two return air inlets are arranged and are staggered at the front and rear positions of the axial direction of the air inlet respectively.
