Abstract
The utility model discloses a novel cooling system for an external air path, which comprises a cooler mounted above a motor casing. One end of the cooler is connected with an air outlet barrel, a fan end shield is connected at a position, which is close to an external fan at the end of a spindle of a motor, on the lower side of the other end of the cooler, the outer side of the fan end shield is connected with an air inlet barrel, an air outlet is disposed at the periphery of the upper end of the air outlet barrel, and a curved air inlet structure is arranged in the air inlet barrel. The novel cooling system has the advantages that noise is reduced, the curved air inlet structure is arranged in the air inlet barrel, curved air inlet is realized, and noise reduction materials are adhered on barrel walls of the air inlet barrel and the air outlet barrel and the total air path.
Description
Technical field
The utility model relates to machine field, especially relates to the exogenous wind line cooling system of motor.
Background technology
The outer wind path part of box motor is cooled off motor from the outside, and present exogenous wind line cooling system has following problem:
Usually adopt cooler and ventilating duct independent separately, and fix, install, hole, make working strength of workers big but do like this by securing member.The producer that has takes air duct out of, but after the chimney fan break-in, the opening of chimney fan need be positioned at the top of cooler, causes the motor whole height to increase.Air duct or air intake tube are not taken in the direct air-out of the producer that has out of, but it is poor to do erasure effect like this, and noise is very big.Though the producer that has takes air duct out of, opening is contained in the side directly from the both sides air-out, and rainwater may fall in the chimney fan.Also have some producers that fan end shield and cooler are made integral body, motor shaft is not easy in the position of fan end shield to adjust, and adjusts very inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of exogenous wind line cooling system that reduces noise, improves degree of protection.
The technical solution of the utility model is:
A kind of novel exogenous wind line cooling system, comprise the cooler that is installed in the motor case top, one end of cooler is connected with chimney fan, the below of the other end is connected with the fan end shield near external fan place, electric machine main shaft end, the fan end shield outside is connected with the air intake tube, end periphery is provided with air outlet on the described chimney fan, is provided with bent road air inlet structure in the described air intake tube.
Described cooler below is provided with the groove that makes things convenient for cooler and support to install and fix, and minor flaps is installed on the groove.
Described chimney fan bottom is provided with osculum.
Described chimney fan upper surface is connected with cover plate, and the cover plate area is greater than the area of section of chimney fan.
The inwall of described air intake tube, chimney fan is provided with quieter material.
Be wind path between air intake tube, the chimney fan, described wind path is provided with quieter material.
Advantage of the present utility model has:
1, reduce noise:
1) is provided with curve air intake wind path in the air intake tube, adopts the curve air intake;
2) be stained with quieter material on air intake tube, chimney fan barrel and the whole wind path.
2, improve degree of protection:
1) cooler is whole is buckled on the motor, and size is slightly larger than motor, and the bolt that is connected with motor is positioned at the groove of cooler bottom;
2) chimney fan is provided with cover plate, and the chimney fan bottom is provided with osculum.
3, reduce height:
Compare the exogenous wind line cooling system of existing chimney fan break-in, the utility model chimney fan height and cooler are contour basically, can not increase the height of equipment, and the user that is more convenient for uses.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in Figure 1, 2, the utility model comprises cooler 1 and chimney fan 2, cooler 1 is connected in aggregates with chimney fan 2, chimney fan 2 is positioned at the left end of cooler 1, the air outlet 7 of chimney fan 2 is located at end periphery on the chimney fan 2, chimney fan 2 upper surfaces are connected with the bigger cover plate of an area 3, and cover plate 3 areas can prevent that greater than the area of section of chimney fan 2 rainwater from entering.Simultaneously offer osculum in chimney fan 2 bottoms.
The right-hand member below of cooler 1 connects fan end shield 4 with bolt, fan end shield 4 is provided with hole near electric machine main shaft right-hand member place, bore hole size is slightly larger than the electric machine main shaft diameter, so that in short transverse or axially adjust fan end shield 4, guarantees that fan end shield 4 can not interfere with electric machine main shaft.Fan end shield 4 can be made the nest shell-type when the unidirectional rotation of external fan.Fan end shield 4 right-hand members are connected with air intake tube 5, and air intake tube 5 adopts bent road air intake, is provided with bent road air intake pipeline 6 in the air intake tube 5.Noise when adopting bent road air intake to reduce air intake.
Be provided with four grooves that concave 8 around cooler 1 bottom, be provided with bolt hole in the groove 8, groove 8 is externally connected with minor flaps 9, during installation, cooler 1 is buckled on the electric machine stand, with bolt that cooler 1 is fixing internally in groove 8 then, cover minor flaps 9 then, do like this and can improve the motor degree of protection, effectively reduce noise of motor.Air intake tube 5, chimney fan 2 are flexible for installation, and the space is limit or noise can remove when not having specific (special) requirements, reduces cost.All be stained with quieter material on air intake tube 5, chimney fan 2 barrels and the whole wind path, to reduce noise.
The utility model outward appearance is simple and clear, and apolegamy reduces labour intensity flexibly, the degree of protection height, and can effectively reduce noise of motor, be specially adapted to the requirement of high-speed electric expreess locomotive low noise sound pitch protection.
