DETAILED DESCRIPTION

[0028] It should be noted that the technical solution of the present invention will be described in detail and completely below in combination with the drawings provided by the present invention and the marks in the drawings, corresponding to the technical solution of the present invention. However, the described content must only be one of the embodiments presented by the technical solution of the present invention, and cannot cover all the contents of the present invention. Therefore, based on the embodiments listed in the present invention, any embodiments derived from the embodiments obtained by those skilled in the art without substantial creation shall fall within the scope of protection of the present invention.

[0029] Embodiment: An automotive generator with active intervention heat dissipation function, such as Figure 1-Figure 4 As shown, it includes a generator body 1, a frame A2, an impeller 3, a temperature control seat 4, a frame B5, a key shaft 6, a clutch plate A7 and a clutch plate B8; an input shaft 101 is arranged on the front side of the generator body 1, and the generator body 1 is connected to the power inside the car through the input shaft 101; a frame A2 is fixedly installed on the rear of the generator body 1; an impeller 3 is rotatably installed on the rear of the frame A2, and the rotating impeller 3 can dissipate heat for the generator body 1; a temperature control seat 4 is fixedly installed on the rear of the generator body 1; a frame B5 is slidably installed on the temperature control seat 4, and the frame B5 moves forward and backward. The frame B5 is located between the generator body 1 and the impeller 3, and the temperature control seat 4 can sense the temperature. When the generator body 1 is used for a long time and generates heat, and the temperature exceeds the preset value of the temperature control seat 4, the temperature control seat 4 will control the frame B5 to move backward. On the contrary, when the temperature drops below the preset value of the temperature control seat 4, the temperature control seat 4 will control the frame B5 to move forward; a key shaft 6 is rotatably installed on the frame B5, and an output shaft 102 is arranged on the rear side of the generator body 1, and the output shaft 102 is connected to the input shaft 101. The key shaft 6 is key-connected to the output shaft 102 of the generator body 1, so that when the frame B5 moves forward and backward, the key shaft 6 can slide relative to the output shaft 102 of the generator body 1 and will not be separated from the output shaft 102, so that the output shaft 102 can always drive the key shaft 6 to rotate; a clutch plate A7 is fixedly installed on the key shaft 6; a clutch plate B8 is fixedly installed on the impeller 3, and when the frame B5 drives the key shaft 6 to move backward, the clutch plate A7 will contact the clutch plate B8, so that the key shaft 6 and the impeller 3 are connected in a contact transmission manner.

[0030] When the generator is used in the engine compartment, after the temperature of the generator body 1 exceeds the temperature value preset by the temperature control seat 4, the temperature control seat 4 starts, and the control frame B5 moves backward, so that the clutch plate A7 on the key shaft 6 contacts the clutch plate B8 on the impeller 3, and then the output shaft 102 on the generator body 1 drives the key shaft 6 to rotate. Since the clutch plate A7 on the key shaft 6 is in contact with the clutch plate B8 of the impeller 3 at this time, the impeller 3 is finally driven to rotate through the cooperation between the clutch plate A7 and the clutch plate B8, thereby accelerating the air flow in the engine compartment and accelerating the heat generated by the generator body 1 to dissipate, thereby preventing the heat from accumulating around the generator body 1. This causes the temperature of the generator body 1 itself to be too high, thereby reducing the damage to the generator caused by high temperature, extending the service life of the generator, and improving the use efficiency of the generator; conversely, when the temperature of the generator body 1 drops below the preset value, the temperature control seat 4 controls the frame B5 to move forward, and the key shaft 6 drives the clutch plate A7 to move forward and separate from the clutch plate B8, disconnecting the transmission relationship between the key shaft 6 and the impeller 3, and stopping the impeller 3 from rotating. Therefore, the generator senses the actual temperature through the temperature control seat 4, controls whether the impeller rotates, and controls whether the generator dissipates heat autonomously, thereby reducing energy waste of the generator body 1.

[0031] like Figure 5-Figure 8As shown, it also includes heat dissipation fins 9, liquid cooling pipes 10, pump body 11, transmission assembly 12 and insulation frame 10a; heat dissipation fins 9 are fixedly installed on frame A2, and the heat dissipation fins 9 are wavy. The wavy heat dissipation fins 9 will be able to greatly increase the heat dissipation area of ​​the generator body 1, improve the heat dissipation capacity of the generator body 1 itself, so that the heat can be dispersed by the impeller 3 in the subsequent process. The heat dissipation fins 9 are wrapped around the outer wall of the generator body 1, and the impeller 3 is arranged on the rear side of the generator body 1. Therefore, under the joint action of the heat dissipation fins 9 and the impeller 3, the generator body 1 can be fully surrounded to dissipate heat, thereby improving the comprehensiveness of the heat dissipation of the generator body 1 and improving the heat dissipation effect of the generator; a liquid cooling pipe 10 is fixedly installed on frame A2, and the liquid cooling pipe 10 is provided with three circles, and the three circles of liquid cooling pipes 10 all pass through the heat dissipation fins 9, and the liquid cooling pipe 1 0 has cooling liquid flowing therein, when the cooling liquid flows in the liquid cooling pipe 10, the heat dissipation fins 9 will be liquid-cooled, and the heat dissipation speed of the heat dissipation fins 9 will be accelerated; a pump body 11 is fixedly installed on the generator body 1, and the pump body 11 is connected with the liquid cooling pipe 10, and the pumped cooling liquid circulates in the liquid cooling pipe 10, and the heat dissipation fins 9 are continuously liquid-cooled. Specifically, the pump body 11 is a centrifugal pump, which generates centrifugal force by the rotation of the blades to pump the cooling liquid; a transmission assembly 12 is installed between the pump body 11 and the impeller 3, and the transmission assembly 12 is used to convert the rotational power of the impeller 3 into the pumping power of the pump body 11; an insulation frame 10a is fixedly connected to the generator body 1, and the insulation frame 10a covers the outside of the liquid cooling pipe 10, reduces the temperature loss of the cooling liquid, and enables the cooling liquid to better act on the heat dissipation fins 9, thereby improving the setting and use of the liquid cooling pipe 10.

[0032] like Figure 7-Figure 8 As shown, the transmission assembly 12 includes a transmission shaft 12a, a gear 12b and a ring gear 12c; the transmission shaft 12a is rotatably mounted on the pump body 11, and the transmission shaft 12a is fixedly connected to the blades in the pump body 11; the gear 12b is fixedly mounted on the transmission shaft 12a; the ring gear 12c is fixedly mounted on the rotating shaft of the impeller 3, and the ring gear 12c is meshed with the gear 12b.

[0033] When the temperature control seat 4 senses that the temperature of the generator body 1 is too high and controls the impeller 3 to rotate for autonomous heat dissipation, the impeller 3 sequentially transmits the power through the gear ring 12c and the gear 12b to provide operating power for the pump body 11, so that the pump body 11 pumps the coolant for circulation to reduce the temperature around the cooling fins 9. In this way, even if the temperature inside the engine compartment of the generator body 1 is too high due to heat dissipation, the cooling fins 9 can also effectively dissipate heat with the help of the coolant, that is, the cooling fins 9 cooperate with the coolant circulating in the liquid cooling pipe 10 to further dissipate heat for the generator body 1 and reduce the temperature of the generator. In addition, with the heat dissipation treatment of the impeller 3, under the double treatment, the generator body 1 can better dissipate heat, improve the heat dissipation effect of the generator, and improve the uniformity of the heat dissipation effect of the generator.

[0034] like Figure 1-Figure 2 As shown, it also includes a protection frame 13; the protection frame 13 is fixedly installed on the generator body 1, and the protection frame 13 covers the outside of the impeller 3. The protection frame 13 protects the components of the generator and improves the safety of the generator.

[0035] The generator is provided with a rotating impeller 3 to dissipate heat on the generator body 1, so as to improve the heat dissipation effect of the generator, extend the service life of the generator, and improve the use efficiency of the generator. In addition, by adding a temperature control seat 4 and clutch plates A7 and B8, whether the impeller 3 rotates is controlled. In other words, the use of the impeller 3 will be directly controlled by the temperature of the generator body 1, so that the generator can dissipate heat autonomously, optimize the use structure of the generator, and reduce energy waste.

[0036] The generator expands the heat dissipation area of ​​the generator body 1 by providing heat dissipation fins 9, and uses liquid cooling pipes 10 in combination so that the coolant assists the heat dissipation fins 9 to dissipate heat, thereby further improving the heat dissipation effect of the generator; and the heat dissipation fins 9 assist in heat dissipation from the periphery of the generator, while the impeller 3 dissipates heat from the rear of the generator. Therefore, it is possible to dissipate heat for the generator in all directions, thereby improving the comprehensiveness of the heat dissipation of the generator.
