Abstract
The utility model discloses a reinforcing car alternator radiating generator protection shroud, including protection shroud main part and wind scooper, be provided with a plurality of screw holes in the protection shroud main part, the wind scooper is connected with the protection shroud main part, is provided with an air inlet entry on the wind scooper, the utility model discloses carry out the sealing treatment with the through-hole of the protection shroud among the prior art, the heat that isolated exhaust supercharging system gived off only remains the used screw hole of fixing bolt, increases the wind scooper in the protection shroud main part, and the air inlet entry on the wind scooper is towards the generator body, and leading-in the air through the wind scooper, will have the generator of this type of wind scooper to install on the engine, and the protection shroud main part of generator can be with the air of keeping away from exhaust supercharging system leading-in to the generator inside because of the reason that the wind scooper exists, for, The support bearing and other parts are practical in heat dissipation.
Description
Technical Field
The utility model relates to an automobile parts technical field, in particular to radiating generator protection shroud of reinforcing car alternator.
Background
In the actual installation and matching of the automobile alternating-current generator, when the installation position of the automobile alternating-current generator is on the leeward side of an engine and is close to an exhaust supercharging system, the environment temperature of the generator is in a high-load state, and even exceeds the high-temperature resistant grade of a rectifying circuit diode, a voltage regulator and support bearing grease. The heat load to parts such as a rectifying circuit inside a generator and a bearing with grease is large, the existing protective cover cooling air guide structure is difficult to meet the cooling requirement of the generator in the severe environment, the original air guide structure can cause failure of the rectifying circuit, frequent opening of a high-temperature protection function of a voltage regulator, deterioration of grease of a supporting bearing and the like, and the normal use of a vehicle is influenced or even fire risks are caused.
The generator protection cover cap in the prior art is a cover cap with a circular concave structure, a plurality of through holes are formed in the generator protection cover cap and used for air inlet, the distance between the generator protection cover cap and the exhaust pressurization system is very short, the temperature of the exhaust pressurization system is high, and then the temperature of air entering the generator is high.
Disclosure of Invention
The utility model aims at providing a reinforcing automobile alternator radiating generator protection shroud can be with the leading-in generator inside of the lower air of temperature, reinforcing heat potential difference, protection rectifier circuit, voltage regulator and bearing grease.
The utility model provides a reinforcing radiating generator protection shroud of car alternator, includes protection shroud main part and wind scooper, is provided with a plurality of screw holes on the protection shroud main part, and the wind scooper is connected with protection shroud main part, is provided with an air inlet entry on the wind scooper.
The utility model discloses a theory of operation:
the utility model discloses seal the through-hole of the protection shroud among the prior art and handle, the heat that isolated exhaust supercharging system gived off, only remain the used screw hole of fixing bolt, increase the wind scooper in the protection shroud main part, the air inlet entry on the wind scooper is towards the generator body, it directly gets into the inside heat dissipation of generator through protection shroud main part rear end by exhaust supercharging system vicinity directly to change among the prior art air, it is leading-in with the air through the wind scooper, wind scooper structural dimension confirms ventilation capacity through hydrodynamics emulation and actual measurement and is X liter per minute (X is greater than generator system actual demand). The generator with the wind scooper is arranged on an engine, and the protective cover cap body of the generator can guide air far away from the exhaust pressurization system into the generator due to the existence of the wind scooper, so that the heat dissipation of parts such as a rectification circuit, a voltage regulator, a support bearing and the like in the generator is practical.
The utility model has the advantages that:
the utility model discloses seal the through-hole of the protection shroud among the prior art and handle, the heat that isolated exhaust supercharging system gived off only remains the used screw hole of fixing bolt, increases the wind scooper in the protection shroud main part, and the air inlet on the wind scooper is towards the generator body, changes among the prior art that the air is direct to get into the inside heat dissipation of generator through protection shroud main part rear end by exhaust supercharging system vicinity, through the wind scooper with the leading-in of air, the utility model discloses can be with the lower air introduction of temperature to the generator inside, reinforcing heat potential difference protects rectifier circuit, voltage regulator and bearing grease.

Detailed Description
Referring to fig. 1 to 2, a generator protecting cover for enhancing heat dissipation of an automotive alternator includes a protecting cover main body 1 and an air guiding cover 2, wherein the protecting cover main body 1 is provided with a plurality of threaded holes 3, the air guiding cover 2 is connected with the protecting cover main body 1, and the air guiding cover 2 is provided with an air inlet 4.
The utility model discloses a theory of operation:
the utility model discloses seal the through-hole of the protection shroud among the prior art and handle, the heat that isolated exhaust supercharging system gived off, only remain the used screw hole of fixing bolt, increase wind scooper 2 in the protection shroud main part 1, 4 orientation generator bodies 5 of air inlet entry on the wind scooper 2, change among the prior art that the air is direct to get into the inside heat dissipation of generator through 1 rear end of protection shroud main part by exhaust supercharging system vicinity, it is leading-in with the air through wind scooper 2, 2 structural dimension of wind scooper confirm ventilation capacity through hydrodynamics emulation and actual measurement and be X liter per minute (X is greater than generator system actual demand). The generator with the wind scooper 2 is mounted on an engine, and the protective cover main body 1 of the generator in fig. 2 introduces air far away from the exhaust pressurization system into the generator due to the existence of the wind scooper 2, and is practical for heat dissipation of parts such as a rectification circuit, a voltage regulator, a support bearing and the like in the generator.
The utility model discloses keep apart the generator with the heat source and introduce the lower air of temperature, can effectively improve the life-span of generator rectifier circuit and bearing grease, effectively reduce the generator failure trouble because the high temperature arouses.
