Abstract
The utility model discloses a generator load tester with a good heat radiation effect. The generator load tester comprises a resistance wire rack and a heat radiation mechanism mounted below the resistance wire rack, wherein the heat radiation mechanism comprises an air box and a fan mounted in the air box; the upper end of the air box is opened, and the opened end of the air box is connected with the resistance wire rack in a sealed manner; the air box is provided with a bottom board; an air inlet is arranged on the bottom board; a motor part of the fan is arranged in the air box; fan blades of the fan are mounted at the position of the air inlet; and air generated by the fan blades is blown into the air box. The air generated by the fan is partially blown upwards to the resistance wire rack directly and is partially blown to the surrounding walls of the air box. The air flows back after being in contact with the surrounding walls, a small circle of the air is generated in the air box, and the air is fully filled in the entire air box, so that a heat radiation blind area at the center of the fan blades is prevented from being formed. Furthermore, the heat of the resistance wire rack can be uniformly radiated.
Description
Technical field
The utility model relates to a kind of proving installation, is meant a kind of isoparametric load testing device of generator power that is used to test especially.
Background technology
The power that genset can be not in place according to environment, tenure of use, the daily servicing of machine room, the replacing of Device element etc. all can occur in various degree descends; Just there is very important potential safety hazard in this, and generator is long-time unloaded or idle, produces carbon distribution; Can cause engine output to reduce like this; Influence the output of the whole power of the assembling unit, even cause the illusion of normal operation, in case the significant trouble that generator can not normally move appears in real load.Therefore also to carry out the load test in the generator daily servicing.
The cooling mechanism that existing generator loading proving installation generally includes the resistance guide frame and is installed on resistance guide frame below; This cooling mechanism is usually by the fan that is uniformly distributed in resistance guide frame below, and this electric fan is positioned at the top of motor part, and the wind of flabellum directly up blows to the resistance guide frame; Though can play certain radiating effect; But fan is when blowing, and the core of flabellum can become the heat radiation blind area usually, and it is inhomogeneous to cause dispelling the heat; In addition, the wind that fan forms can cause the significant wastage of wind energy in a large number to diffusion all around.
The utility model content
The utility model provides a kind of radiating effect good generator loading proving installation, and its purpose is to overcome that prior art exists because the existence of heat radiation blind area influences radiating effect and the serious defective of wind energy waste.
The technical scheme of the utility model is following:
The generator loading proving installation that a kind of radiating effect is good, the cooling mechanism that comprises the resistance guide frame and be installed on resistance guide frame below, said cooling mechanism comprise bellows and are installed on the fan in the bellows; Uncovered and its opening end in the upper end of said bellows and resistance guide frame are tightly connected; Said bellows have a base plate, offer air inlet on this base plate, and the motor portion of said fan is positioned at bellows; The flabellum of said fan is installed on the air inlet place, and the wind that flabellum forms is in bellows.
As the improvement of the utility model, evenly offer at least two air inlets on the said base plate, the flabellum of said fan is installed on the air inlet place correspondingly.
As the improvement of the utility model, said bellows are cuboid, and three groups of fans evenly are installed on its base plate, and every group of fan is made up of left and right two fans.
As the further improvement of the utility model, the height of said bellows is 25-40cm.
As the further improvement of the utility model, the height of said bellows is 30cm.
Can know that by above-mentioned description compare with prior art, the advantage of the utility model is to the utility model:
1, the wind part of fan formation directly up blows to the resistance guide frame; Part blows to the leg of bellows, after running into leg, refluxes, and makes wind in bellows, form partial circulating and is full of whole bellows; Thereby avoided the formation of heat radiation blind area, flabellum center, and then the resistance guide frame is dispelled the heat uniformly.
2, when having a plurality of fan in the bellows, each fan can mix each other and separately the weak zone of flabellum center wind-force is replenished, thereby makes the wind-force in the whole bellows even, and then makes the resistance guide frame obtain better radiating effect.
3, partly be installed in the bellows below when the motor of fan, promptly the wind of fan is positive when up blowing, because the motor part has certain height usually, has therefore intangibly increased the whole height of generator loading proving installation.In addition, the wind itself that fan forms can partly dispel the heat to motor, no longer needs miscellaneous equipment to divide heat radiation to motor section, has saved equipment cost.

The bellows polycrystalline substance synoptic diagram of Fig. 2 embodiment one.
Fig. 3 is the bellows polycrystalline substance synoptic diagram of embodiment two.
Embodiment
The embodiment of the utility model is described with reference to the accompanying drawings.
Embodiment one
With reference to Fig. 1, the generator loading proving installation that a kind of radiating effect is good comprises resistance guide frame 1 and the cooling mechanism that is installed on resistance guide frame 1 below, the fan 4 that cooling mechanism comprises bellows 2 and is positioned at bellows 2.Simultaneously with reference to Fig. 2; Bellows 2 are cuboid; Uncovered and its opening end in its upper end and resistance wire 1 are tightly connected, and said bellows 2 have a base plate 3, evenly offer three air inlet groups on this base plate 3; Each air inlet group is formed by left and right two air inlets 31, and the flabellum 41 of fan 4 is installed on air inlet 31 places correspondingly; The motor portion 42 of fan 4 is positioned at bellows 2.
The wind of each fan 4 all is to be inverted taper shape to diffusion all around, and the also mixing of intersection each other of the conical wind territory between the adjacent fans 4 makes the wind-force of flabellum 41 central areas be enhanced than weak part.In addition, when wind was run into the leg of bellows 2, wind will reflux and in bellows 2, spread everywhere and form partial circulating, finally made the wind in the bellows 2 be tending towards equally distributed state, and then helped the heat radiation of resistance guide frame 1.
In addition, in order to reach desirable radiating effect, the height of above-mentioned bellows 2 is generally about 30cm.
Embodiment two
With reference to Fig. 3, the structure of present embodiment and the foregoing description one is basic identical, and its key distinction is, offers four air inlets 31 ' on the base plate 3 ' of the bellows 2 ' of present embodiment, and each air inlet 31 ' locates all to be equipped with fan 4 '.
The above-mentioned embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
