Description

Technical Field

[0001] The present application relates to the technical field of generators, and in particular to a heat dissipation component and a generator. Background Art

[0002] The generator includes components such as an inverter module, a powertrain and a fuel tank. The powertrain converts the oil in the fuel tank into alternating current, which is then transmitted to the inverter module and then converted into direct current for output. During the operation of the generator, the inverter module will generate a large amount of heat. The heat accumulated inside the generator can easily cause the temperature of the generator to be too high, thus affecting the normal operation of the generator. In the related art, heat is dissipated by setting a radiator inside the generator, but this heat dissipation method is inefficient, and after the generator has been working for a long time, it is still easy to generate heat accumulation.

[0059] The generator includes components such as an inverter module, a powertrain and a fuel tank. The powertrain converts the oil in the fuel tank into alternating current, which is then transmitted to the inverter module and then converted into direct current for output. During the operation of the generator, the inverter module will generate a large amount of heat. The heat accumulated inside the generator can easily cause the temperature of the generator to be too high, thus affecting the normal operation of the generator. In the related art, heat is dissipated by setting a radiator inside the generator, but this heat dissipation method is inefficient, and after the generator has been working for a long time, it is still easy to generate heat accumulation.

[0060] An embodiment of the present application provides a heat dissipation assembly, which is applied to a generator, wherein the generator has an inverter module and an air supply port, and the air supply port is configured to allow air to enter the generator. The heat dissipation assembly includes a shroud, an air guide, and a radiator. The shroud has an air inlet. The air guide is disposed on one side of the shroud, and the air guide is configured to connect the air inlet with the air supply port; the radiator is used for heat exchange with the inverter module, and the radiator is disposed on a side of the shroud away from the air guide; the front of the radiator is exposed to the air inlet, a first flow channel is formed between the front of the radiator and the shroud, an air outlet is formed between the side of the radiator and the shroud, and the first flow channel connects the air inlet and the air outlet.

[0061] In the above heat dissipation assembly, the airflow outside the generator can reach the air guide from the air supply port, and can enter the air inlet from the air guide. The air guide can guide the airflow entering the generator to the air inlet of the air guide cover as much as possible to increase the air intake of the air inlet. At the same time, a first flow channel is formed between the air guide cover and the front of the radiator, and an air outlet is formed between the air guide cover and the side of the radiator. The airflow entering the air inlet passes through the first flow channel and enters the inside of the generator from the air outlet. That is, the airflow will flow through the front and side of the radiator to fully contact the radiator, increasing the heat dissipation area of ​​the radiator, thereby effectively taking away the heat of the radiator, with high heat dissipation efficiency and improved heat dissipation effect.

[0064] See also Figure 1 and Figure 2 In some embodiments, the housing 201 has an air supply port 2011 and an air exhaust port 2012, and the air supply port 2011 is configured to allow airflow to enter the generator 200. The exhaust fan 205 is configured to allow airflow outside the generator 200 to enter the housing 201. When the exhaust fan 205 is working, the external airflow can enter the housing 201 from the air supply port 2011. During the airflow flowing in the housing 201, it can pass through the heat dissipation component 100, the inverter module 204 and the power assembly 202, thereby taking away the heat in the housing 201 and discharging it from the exhaust port 2012, thereby effectively dissipating the heat inside the generator 200 and reducing the heat accumulation inside the generator 200.

[0065] See also Figures 1 to 3In some embodiments, the air supply port 2011 and the air exhaust port 2012 are arranged opposite to each other, and along the direction from the air supply port 2011 to the air exhaust port 2012, the heat dissipation component 100, the inverter module 204, the exhaust fan 205, and the power assembly 202 are sequentially arranged between the air supply port 2011 and the air exhaust port 2012, and the oil tank 203 is located above the heat dissipation component 100, the exhaust fan 205, and the power assembly 202. In the process of the airflow entering the housing 201 from the air supply port 2011 and being discharged from the air exhaust port 2012, the airflow can sequentially pass through the heat dissipation component 100, the inverter module 204, the exhaust fan 205, and the power assembly 202 in the housing 201, and can sequentially take away the heat generated by the heat dissipation component 100, the inverter module 204, the exhaust fan 205, and the power assembly 202, thereby improving the heat dissipation effect.

The first handle 206 and the second handle 207 transmit the force to the bottom shell 2016 through the front shell 2013, the rear shell 2014 and the two side shells 2017, so that the force of the first handle 206 and the second handle 207 can be transmitted to the bottom shell 2016 without additional internal support, so that the overall force is evenly distributed, and the outer shell 201 is prevented from being damaged by excessive local force, thereby improving the structural strength of the outer shell 201. At the same time, the force can be transmitted to the bottom shell 2016 without the need for additional internal support structures, which can reduce the weight of the whole machine and reduce costs.

[0068] The two tops 2017b and the top cover 2015 can be formed together above the generator 200 to increase the thickness of the housing 201 above the generator 200, thereby providing protection for the top of the generator 200. The first handle 206 and the second handle 207 on the top cover 2015 facilitate the user to move the generator 200 by holding the first handle 206 and the second handle 207, thereby improving the convenience of moving the generator 200.

[0069] The front shell 2013 is connected to the two side shells 2017, which may mean that the front shell 2013 is connected to the side portions 2017a and the top portion 2017b of the two side shells 2017. The rear shell 2014 is connected to the two side shells 2017, which may mean that the rear shell 2014 is connected to the side portions 2017a and the top portion 2017b of the two side shells 2017, so as to further improve the overall structural strength of the housing 201.

[0070] See also Figure 1 and Figure 2 In some embodiments, the air supply port 2011 is disposed on the front shell 2013, and the air exhaust port 2012 is disposed on the rear shell 2014.

[0077] See also Figure 2 , Figures 4 to 8 In some embodiments, the heat dissipation assembly 100 includes a bracket 10, an air guide 20, and a radiator 30.

The radiator 30 is disposed on a side of the air guide 11 away from the air guide 20. The front of the radiator 30 is exposed to the air inlet 1111, and a first flow channel 40 is formed between the front of the radiator 30 and the air guide 11, and an air outlet 50 is formed between the side of the radiator 30 and the air guide 11, and the first flow channel 40 connects the air inlet 1111 and the air outlet 50.

The air guide 20 can guide the airflow entering the generator 200 to the air inlet 1111 of the air guide 11 as much as possible, thereby increasing the air intake of the air inlet 1111. At the same time, a first flow channel 40 is formed between the air guide 11 and the front of the radiator 30, and an air outlet 50 is formed between the air guide 11 and the side of the radiator 30, so that the airflow entering the air inlet 1111 passes through the first flow channel 40 and then enters the inside of the generator 200 from the air outlet 50, that is, the airflow will flow through the front and side of the radiator 30 to fully contact the radiator 30, thereby increasing the heat dissipation area of ​​the radiator 30, thereby effectively taking away the heat of the radiator 30, with high heat dissipation efficiency and improved heat dissipation effect.

[0079] See also Figure 5 In some embodiments, the air guide 20 has an air duct 21, and a first end 22 and a second end 23 arranged opposite to each other. The first end 22 is configured to face the air supply port 2011 so that one end of the air duct 21 is connected to the air supply port 2011; the second end 23 is configured to fit the wall of the air guide cover 11 so that the air inlet 1111 is completely located at the other end of the air duct 21, which is conducive to the airflow in the air duct 21 to be able to completely enter the first flow channel 40 from the air inlet 1111, thereby ensuring the air intake of the first flow channel 40.

[0080] See also Figures 5 to 8 In some embodiments, the air outlet 50 includes a first sub-air outlet 51 and a second sub-air outlet 52 located on two opposite sides of the radiator 30, one end of the first flow channel 40 is connected to the first sub-air outlet 51, and the other end is connected to the second sub-air outlet 52, and the air inlet 1111 is located between the first sub-air outlet 51 and the second sub-air outlet 52.

[0081] The arrangement of the first sub-air outlet 51 and the second sub-air outlet 52 allows the airflow in the first flow channel 40 to be divided into two parts, one part is discharged from the first sub-air outlet 51, and the other part is discharged from the second sub-air outlet 52, thereby accelerating the flow rate of the airflow and improving the heat dissipation efficiency. In addition, the first sub-air outlet 51 and the second sub-air outlet 52 are respectively located on the two sides of the radiator 30, so that the airflow can flow through the radiator 30 toward the entire surface of the air guide cover 11, which can increase the contact area between the airflow and the radiator 30, thereby facilitating the effective removal of heat from the radiator 30 and further improving the heat dissipation effect.

[0082] See also Figures 5 to 8In some embodiments, the air guide cover 11 includes a first air guide portion 111, a second air guide portion 112 and a third air guide portion 113. The first air guide portion 111 is connected between the second air guide portion 112 and the third air guide portion 113. The first air guide portion 111 has an air inlet 1111. The second air guide portion 112 and the third air guide portion 113 are arranged opposite to each other. The surface of the radiator 30 facing the second air guide portion 112 and the third air guide portion 113 is the two side surfaces of the radiator 30. A first sub-air outlet 51 is formed between the second air guide portion 112 and the radiator 30, and a second sub-air outlet 52 is formed between the third air guide portion 113 and the radiator 30. The surface of the radiator 30 facing the first air guide portion 111 is the front surface of the radiator 30.

[0083] After the airflow enters the air inlet 1111, a part of the airflow flows along the first air guide 111 to the second air guide 112 and is discharged from the first sub-air outlet 51; the other part of the airflow flows along the first air guide 111 to the third air guide 113 and is discharged from the second sub-air outlet 52. The air inlet 1111 is arranged at the first air guide 111, that is, the air inlet 1111 is located between the first sub-air outlet 51 and the second sub-air outlet 52, so as to improve the consistency of the time when the airflow reaches the first sub-air outlet 51 and the time when the airflow reaches the second sub-air outlet 52, so as to facilitate uniform heat dissipation of the radiator 30.

[0084] See also Figures 4 to 8 In some embodiments, the air guide cover 11 also includes a fourth air guide portion 114 and a fifth air guide portion 115, the fourth air guide portion 114 is connected to the second air guide portion 112 and is located at the first sub-air outlet 51, and the fourth air guide portion 114 is bent toward the third air guide portion 113 relative to the second air guide portion 112; the fifth air guide portion 115 is connected to the third air guide portion 113 and is located at the second sub-air outlet 52, and the fifth air guide portion 115 is bent toward the fourth air guide portion 114 relative to the third air guide portion 113; the fourth air guide portion 114 and the fifth air guide portion 115 are both located on the side of the radiator 30 away from the air inlet 1111.

[0085] The airflow at the first sub-air outlet 51 can flow along the fourth air guide 114 and pass through the side of the radiator 30 away from the air inlet 1111 during the flow; the airflow at the second sub-air outlet 52 can flow along the fifth air guide 115 and pass through the side of the radiator 30 away from the air inlet 1111 during the flow. After the airflow passes through the first flow channel 40 to dissipate heat on the side of the radiator 30 close to the air inlet 1111, it can also dissipate heat on the side of the radiator 30 away from the air inlet 1111, thereby further improving the heat dissipation effect of the radiator 30.

[0086] See also Figures 4 to 8In some embodiments, the first guide portion 111 , the second guide portion 112 , the third guide portion 113 , the fourth guide portion 114 and the fifth guide portion 115 are all substantially in the shape of a flat plate.
