Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator technology, and in particular to a generator with multi-channel heat dissipation. Background Technology
[0002] As the main power source of a car, the car alternator is responsible for supplying power to all electrical equipment (except the starter motor) and charging the battery when the engine is running normally. Traditional car alternators are usually based on the three-phase stator windings of a regular alternator, and their performance is improved by increasing the number of winding turns and adding a three-phase bridge rectifier. In actual operation, the alternator will generate a lot of heat due to electromagnetic induction and current transmission. If it cannot be dissipated in a timely and effective manner, the internal temperature will continue to rise, which will seriously affect the power generation efficiency, accelerate the aging of components, and even cause safety hazards.
[0003] In the existing technology, most vehicle generators adopt a relatively simple heat dissipation solution, usually relying on a single heat dissipation duct or natural convection for heat dissipation. The heat dissipation efficiency is limited, especially under low engine speed or high load conditions. Due to insufficient heat dissipation airflow, heat is easily accumulated, leading to a decrease in generator performance. Existing heat dissipation structures are often highly integrated and difficult to disassemble, which makes cleaning and maintenance difficult and further affects the long-term stable operation of the heat dissipation system. Therefore, a generator with multi-duct heat dissipation is needed to meet people's needs. Utility Model Content
[0004] In view of the above problems, the technical problem to be solved by this utility model is to provide a generator with multi-channel heat dissipation.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a multi-channel heat dissipation generator, including a generator, characterized in that: a support frame one and a support frame two are arranged on the generator, an exhaust hood is installed at one end of the generator, an air intake fan hood is arranged at the other end of the generator, an internal heat dissipation air duct one and an internal heat dissipation air duct two are opened inside the generator, the internal heat dissipation air duct one is located outside the rotor, the internal heat dissipation air duct two is located between the stator and the rotor, and multiple sets of external heat dissipation air ducts are equally spaced on the outside of the generator.
[0006] A further preferred embodiment of this utility model is: an exhaust hole is provided on the exhaust cover, and an exhaust fan is fixedly installed on the generator shaft.
[0007] A further preferred embodiment of this utility model is: a mounting bracket is fixedly installed inside the air intake fan cover, and a cooling fan is fixedly installed on the mounting bracket. The cooling fan is compatible with the external cooling air duct, the first internal cooling air duct, and the second internal cooling air duct.
[0008] A further preferred embodiment of this utility model is as follows: an L-shaped rod is fixedly installed on the bottom side of the air intake fan cover, a rotating shaft is fixedly installed on the L-shaped rod, a connecting rod is rotatably installed on the rotating shaft, and the connecting rod is fixedly installed on the support frame two.
[0009] A further preferred embodiment of this utility model is that a dustproof net is fixedly installed on the air intake end of the air intake fan cover.
[0010] A further preferred embodiment of this utility model is as follows: a positioning rod is fixedly installed at the top of the air intake fan cover, a positioning seat is fixedly installed at the top of the support frame two, a positioning pin is slidably installed on the positioning seat, and the positioning rod and the positioning pin are compatible.
[0011] A further preferred embodiment of this utility model is: a positioning groove is provided on the positioning seat, a positioning spring is fixedly installed in the positioning groove, and one end of the positioning spring is fixedly installed on the positioning pin.
[0012] Compared with the prior art, the present invention has the following advantages: by setting up an external heat dissipation duct, an internal heat dissipation duct one, and an internal heat dissipation duct two, multiple independent and collaborative heat dissipation ducts are constructed inside and outside the generator, which significantly increases the heat dissipation area and the airflow efficiency. It can quickly dissipate the heat generated during generator operation from multiple parts such as the stator, rotor, and casing, effectively avoiding heat accumulation, thereby ensuring the stable working efficiency and operational safety of the generator.
[0013] By installing an independent cooling fan on the outside, cooling airflow can be actively supplemented when the generator is running at low speed or when its own airflow is insufficient, ensuring that there is sufficient airflow through the internal and external air ducts under all operating conditions to maintain good heat dissipation. This design overcomes the defect of traditional generators where heat dissipation capacity decreases at low speeds and improves the environmental adaptability and reliability of the whole machine.

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
[0019] This embodiment mainly describes a generator with multi-channel heat dissipation, as detailed below: like Figures 1-4 As shown, a multi-channel heat dissipation generator includes a generator 1, on which a support frame 101 and a support frame 102 are arranged. An exhaust hood 3 is installed at one end of the generator 1, and an intake fan hood 4 is arranged at the other end of the generator 1. An internal heat dissipation channel 1 2 and an internal heat dissipation channel 201 are opened inside the generator 1. The internal heat dissipation channel 1 2 is located outside the rotor, and the internal heat dissipation channel 201 is located between the stator and the rotor. Multiple sets of external heat dissipation channels 103 are equidistantly opened on the outside of the generator 1.
[0020] The exhaust hood 3 has an exhaust hole 301, and the generator 1 has an exhaust fan 302 fixedly installed on its shaft. Specifically, the exhaust fan 302 works in conjunction with the cooling fan 402 inside the device to simultaneously deliver and draw air at the air inlet and outlet ends, ensuring rapid airflow.
[0021] A mounting bracket 401 is fixedly installed inside the air intake fan cover 4. A cooling fan 402 is fixedly installed on the mounting bracket 401. The cooling fan 402 is compatible with the external cooling air duct 103, the internal cooling air duct 1 2, and the internal cooling air duct 2 201. Specifically, the airflow generated by the cooling fan 402 flows through the external cooling air duct 103, the internal cooling air duct 1 2, and the internal cooling air duct 2 201. The flowing air dissipates heat in both the inner and outer parts of the generator 1. The multiple air ducts work together to improve the equipment's self-heating efficiency.
[0022] An L-shaped rod 404 is fixedly installed on the bottom side of the intake fan cover 4. A rotating shaft 406 is fixedly installed on the L-shaped rod 404. A connecting rod 405 is rotatably installed on the rotating shaft 406. The connecting rod 405 is fixedly installed on the support frame 102. Specifically, the L-shaped rod 404, the connecting rod 405, and the rotating shaft 406 are used to realize the rotation of the intake fan cover 4, thereby unfolding the intake fan cover 4 to facilitate the maintenance of the cooling fan 402.
[0023] A dustproof net 403 is fixedly installed at the air intake end of the air intake fan cover 4. A mounting bracket 401 is used at the air intake end of the air intake fan cover 4 to prevent dust and avoid large particles of impurities from entering the device.
[0024] A positioning rod 5 is fixedly installed at the top of the intake fan cover 4, and a positioning seat 501 is fixedly installed at the top of the support frame 102. A positioning pin 502 is slidably installed on the positioning seat 501. The positioning rod 5 and the positioning pin 502 are adapted to each other. A positioning groove 503 is opened on the positioning seat 501. A positioning spring 504 is fixedly installed in the positioning groove 503. One end of the positioning spring 504 is fixedly installed on the positioning pin 502. Specifically, when the intake fan cover 4 is in use, it is fixed by the positioning rod 5 and the positioning seat 501 to ensure that the position of the intake fan cover 4 relative to the generator 1 is fixed. The positioning pin 502 moves on the positioning seat 501 and locks one end of the positioning rod 5. Under the restriction of the positioning spring 504, the positioning pin 502 can move in the positioning groove 503, thus having an automatic limiting function. Moving the positioning pin 502 into the positioning groove 503 can release the restriction on the position of the positioning rod 5.
[0025] Working principle: During operation, this device requires the cooling fan 402 to drive. The airflow generated by the cooling fan 402 flows through the outer cooling duct 103, the inner cooling duct 1 2, and the inner cooling duct 2 201. The flowing air dissipates heat in both the inner and outer parts of the generator 1. The multiple air ducts work together to improve the device's self-cooling efficiency. Furthermore, an exhaust fan 302 works in conjunction with the cooling fan 402 to simultaneously deliver and draw air at the inlet and outlet ends, ensuring rapid airflow. For maintenance, the intake fan shroud 4 can be rotated using the L-shaped rod 404, connecting rod 405, and rotating shaft 406 to allow the air intake fan to be rotated. The fan cover 4 can be unfolded to facilitate the maintenance of the cooling fan 402. The air intake end of the fan cover 4 is protected from dust by the mounting bracket 401 to prevent large particles of impurities from entering the device. When in use, the fan cover 4 is fixed by the positioning rod 5 and the positioning seat 501 to ensure that the position of the fan cover 4 relative to the generator 1 is fixed. The positioning pin 502 moves on the positioning seat 501 and locks one end of the positioning rod 5. Under the restriction of the positioning spring 504, the positioning pin 502 can move in the positioning groove 503, thus having an automatic limiting function. Moving the positioning pin 502 into the positioning groove 503 will release the restriction on the position of the positioning rod 5.
