Description

A kind of automobile current generator and the attachment structure of guide duct

Technical field

This utility model relates to automobile current generator, is specifically related to the attachment structure of a kind of automobile current generator and guide duct.

Background technology

Automobile current generator is the main power source of automobile, and its function is when normal working of engine, powers to all electrical equipments in addition to starter, charges to accumulator simultaneously.Along with the progress of automotive engineering, the power consumption of automobile is more and more higher, and automobile generating acc power is consequently increased, and causes engine radiating amount to increase.Generation current machine has two kinds of arrangements on the engine, and one is arranged on air inlet side, and one is arranged on exhaust side.For by generator arrangements in the structure of the exhaust side of engine, electromotor works the most under the high temperature conditions, relies solely on natural wind and cannot be carried out effectively dispelling the heat, and so can cause the hydraulic performance decline of electromotor, thus the problem such as cause electrical appliance work abnormal.CN101877512A is disclosed " a kind of electromotor with guide duct ", including engine block and guide duct.Guide duct is arranged at rear cover for generator, the air inlet of described guide duct is rectangle cartridge type, the rear end of rectangle cartridge type air inlet connects semicircular guide duct runner, the circumferential distribution of described guide duct runner has clamp, with rear cover for generator clamping, guide duct runner is identical with the air channel, inside of electromotor, and designs bolt hole on guide duct, bolt be connected by guide duct fixing with rear cover for generator.Using said structure, cold wind enters from the air inlet of guide duct, enters back into generator through guide duct runner, and cold wind absorbs heat after generator circulates, and from engine block, air outlet flows out.Visible by increasing guide duct on electromotor, thermal source can be separated and change the flow direction of wind, and then improving the working environment of electromotor, effectively reducing the ambient temperature of electromotor, improve generator performance and life-span.This is undoubtedly a kind of new trial in this field, but also needs to improve further.

Summary of the invention

The purpose of this utility model is to provide the attachment structure of a kind of automobile current generator and guide duct, and it takes up room little, it is possible to effectively cool down electromotor, extends the service life of electromotor；Simple in construction, compact simultaneously.

A kind of automobile current generator described in the utility model and the attachment structure of guide duct, including engine block and the rear cover that engine block is connected, it is positioned at the radiator on the right side of engine block, it is characterized in that: also include being located at the rectangle air inlet on the right side of described rear cover and the guide duct of rectangle air inlet clamping；Described guide duct is made up of the first rectangular tube, the second rectangular tube and the 3rd rectangular tube, and the right-hand member of described first rectangular tube and the rear end of the second rectangular tube connect, and the front end of described second rectangular tube is connected with the left end of the 3rd rectangular tube；The right-hand member of described 3rd rectangular tube is corresponding with described radiator.

Further, the surrounding of described first rectangular tube is equipped with clamp, being formed around and the draw-in groove of described clamp corresponding matching of described rectangle air inlet；Described rectangle air inlet and guide duct are by described clamp and draw-in groove clamping.

Further, described clamp is wedge shaped.

The technique effect that this utility model is useful:

Owing to changing the shape of guide duct so that guide duct, just to radiator, decreases and takes up room, and effectively cools down electromotor, extend the service life of electromotor；Owing to changing the shape of clamp and draw-in groove so that structure is simpler, compact.

Detailed description of the invention

Below in conjunction with accompanying drawing and preferred embodiment, this utility model is elaborated, it is to be understood that protection domain of the present utility model is not limited by detailed description of the invention.

See Fig. 1 and Fig. 2, the attachment structure of a kind of automobile current generator and guide duct, including engine block 1 and the rear cover 2 that engine block 1 is connected, it is positioned at the radiator on the right side of engine block 1, its substantive distinguishing features is:

Also include being located at the rectangle air inlet 21 on the right side of described rear cover 2 and the guide duct 3 of rectangle air inlet 21 clamping；Seeing Fig. 3, described guide duct 3 is made up of first rectangular tube the 31, second rectangular tube 32 and the 3rd rectangular tube 33, and the right-hand member of described first rectangular tube 31 and the rear end of the second rectangular tube 32 connect, and the described front end of the second rectangular tube 32 is connected with the left end of the 3rd rectangular tube 33；The right-hand member of described 3rd rectangular tube 33 is corresponding with described radiator.The design of guide duct decreases and takes up room, it is possible to effectively cools down electromotor, extends the service life of electromotor.

See the surrounding of the first rectangular tube 31 described in Fig. 3 and be equipped with clamp 4, see Fig. 2, being formed around and the draw-in groove 5 of described clamp 4 corresponding matching of described rectangle air inlet 21；Described rectangle air inlet 21 and guide duct 3 are by described clamp 4 and draw-in groove 5 clamping.

Seeing Fig. 4, described clamp 4 is wedge shaped.

Clamp and the design of draw-in groove so that structure is simpler, compact.Ensureing that rectangle air inlet 21 is connected under premise reliable, tight with guide duct 3, clamp and the quantity of draw-in groove and position can according to specific circumstances depending on, can be four, five, seven, eight etc..

Radiator wind enters rear cover 2 by guide duct 3 and rectangle air inlet 21, by the cooling fan of engine block 1 by the inside of radiator wind inspiration engine block, cools down electromotor, it is ensured that the functional reliability of electromotor.
