The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0035] See also Figure 1The radiator 100 includes a substrate 1 and a plurality of heat sinks 2. A plurality of first heat dissipation channels 11 are spaced apart, and a plurality of heat sinks 2 are fixed to one surface of the substrate 1. Second heat dissipation channels 3 are formed between two adjacent heat sinks 2. There are multiple second heat dissipation channels 3, and the second heat dissipation channels 3 are used to allow airflow to flow through, so that both the substrate 1 and the heat sinks 2 exchange heat with the airflow to dissipate heat. One surface of the substrate 1 is the surface of the substrate 1 away from the heat source, and the other surface of the substrate 1 is used to be fixed to the heat source, thereby receiving heat from the heat source and transferring the heat to the heat sink 2. In some embodiments, the heat source is a motorcycle controller.

[0036] For the above substrate 1, see Figure 1 The substrate 1 is provided with a plurality of first heat dissipation channels 11. The plurality of first heat dissipation channels 11 are arranged at intervals, and the first heat dissipation channels 11 penetrate the substrate 1. The first heat dissipation channels 11 are used for allowing airflow to flow through, thereby performing heat exchange with the airflow to dissipate heat.

[0037] In some embodiments, see Figure 1 The cross-section of the first heat dissipation channel 11 is circular, and the cross-section of the first heat dissipation channel 11 is a cross-section from one surface to the other surface of the substrate 1. Of course, the cross-section of the first heat dissipation channel 11 can also be square, elliptical, triangular or trapezoidal.

[0038] In some embodiments, in order to reduce the space occupied by the radiator 100, a receiving groove 12 is provided on one surface of the substrate 1, and the receiving groove 12 passes through the substrate 1. The bottom of the receiving groove 12 is fixed to multiple heat sinks 2. The heat sink 2 located on the outermost side is spaced apart from the first side wall of the receiving groove 12 to form a second heat dissipation channel 3, and the heat sink 2 located on the other outermost side is spaced apart from the second side wall of the receiving groove 12 to form a second heat dissipation channel 3.

[0039] In some embodiments, see Figure 2 The heat sink 100 includes a guide member 4 . The guide member 4 is fixed to one end of the substrate 1 . The direction from one end to the other end of the substrate 1 is the flow direction of the airflow. The guide member 4 is used to guide the airflow to the first heat dissipation channel 11 .

[0040] In some embodiments, in order to reduce the space occupied by the heat sink 100 , a first accommodating groove 13 is provided at one end of the substrate 1 . The first accommodating groove 13 is connected to the first heat dissipation channel 11 and accommodates at least a portion of the guide member 4 .

[0041] In some embodiments, see Figure 2The heat sink 100 also includes a flow concentrator 5, which includes a fixed plate 51 and a plurality of flow concentrators 52. The fixed plate 51 is fixed to one surface of the substrate 1, and is provided with a plurality of openings 511. The plurality of openings 511 are spaced apart from one end of the flow concentrator 5 to the other end. One side of the flow concentrator 52 is fixed to the opening 511, so that the plurality of flow concentrators 52 are spaced apart, and the other side of the flow concentrator 52 protrudes from the fixed plate 51. The flow concentrator 52 is provided with a flow concentrating channel 521, which is connected to the second heat dissipation channel 3. The flow concentrator 52 allows the irregular airflow to be orderly concentrated in the flow concentrating channel 521, and the airflow is guided to the second heat dissipation channel 3, thereby accelerating the airflow speed in the second heat dissipation channel 3, improving the heat dissipation efficiency, and enhancing the heat dissipation effect.

[0042] It is understood that in some embodiments, see Figure 3 and Figure 4 The radiator 100 is not limited to the above structure and may also have other structures. The radiator 100 includes a fluid supply assembly 6, which includes multiple connecting tubes 61 and a fluid source. In addition to the other end of the outermost first heat dissipation channel 11 and the other end of the outermost first heat dissipation channel 11, one end of each adjacent first heat dissipation channel 11 is connected to one end of the tube 61, one end of each adjacent first heat dissipation channel 11 is connected to the other end of the tube 61, and the other end of each adjacent first heat dissipation channel 11 is connected to one end of the connecting tube 61, and the other end of each adjacent first heat dissipation channel 11 is connected to the other end of the connecting tube 61. Thus, the multiple first heat dissipation channels 11 are sequentially connected through the multiple connecting tubes 61 to form fluid flow channels. One end of the fluid flow channel is connected to the fluid source.

[0043] The fluid source includes an air source. The air source is connected to one end of the fluid flow channel. In other words, the air source is connected to the other end of the first heat dissipation channel 11 located on the outermost side. The other end of the fluid channel is connected to the outside world. In other words, the other end of the first heat dissipation channel 11 located on the outermost side is connected to the outside world, so that the airflow flowing through the fluid flow channel flows out to the outside world from the other end of the fluid flow channel. The air source is used to supply air to the fluid flow channel, so that the airflow flows along the fluid channel to exchange heat with the substrate 1 to dissipate heat.

[0044] In some embodiments, the gas source is an air pump.

[0045] It will be appreciated that in some embodiments, the fluid source is not limited to the above-described structure and may also have other structures, including a fluid pump and a fluid tank. The fluid pump connects one end of the fluid flow channel to the fluid tank. The fluid tank connects the other end of the fluid flow channel, so that the fluid pump, the fluid flow channel, and the fluid tank form a heat dissipation circuit. The fluid tank is used to contain a first fluid. The fluid pump draws the first fluid from the fluid tank and causes it to flow back to the fluid tank along the fluid flow channel. As the first fluid flows through the fluid flow channel, it exchanges heat with the substrate 1 to dissipate heat.

[0046] In some embodiments, the fluid pump is a water pump, and the first fluid may be a cooling medium such as coolant, cooling oil, etc.

[0047] In some embodiments, the fluid supply assembly 6 further includes a plurality of connectors 62. A connector 62 is fixed to each end of each first heat dissipation channel 11. The connector 62 fixed to the other end of the outermost first heat dissipation channel 11 is connected to a fluid source, and the connector 62 fixed to the other end of the other outermost first heat dissipation channel 11 is connected to a fluid source or is used to connect to the outside world. In addition to the connector 62 fixed to the other end of the outermost first heat dissipation channel 11 and the connector 62 fixed to the other end of the other outermost first heat dissipation channel 11, every two adjacent connectors 62 are respectively connected to one end and the other end of a connecting tube 61.

[0048] In some embodiments, in order to facilitate the installation of the connector 62 , threads are provided at one end and the other end of the first heat dissipation channel 11 , so that both ends of the first heat dissipation channel 11 are screwed and fixed to the connecting tube 61 structure through the threads.

[0049] In some embodiments, a portion of the connector 62 fixed to one end of the first heat dissipation channel 11 is received in the first receiving groove 13. A second receiving groove 14 is further provided at the other end of the substrate 1. The second receiving groove 14 communicates with the first heat dissipation channel 11 and receives the portion of the connector 62 fixed to the other end of the first heat dissipation channel 11. The first receiving groove 13 and the second receiving groove 14 reduce the space occupied by the heat sink 100.

[0050] It is understandable that, in some embodiments, in order to improve the heat dissipation efficiency and enhance the heat dissipation effect, the radiator 100 includes not only the flow supply component 6 but also the flow focusing component 5 .

[0051] It is understood that in some embodiments, see Figure 5 and Figure 6The radiator 100 is not limited to the above structure. The radiator 100 can also be other structures. The radiator 100 includes multiple first plugs 7, multiple second plugs 8 and a second fluid. The first plug 7 is fixed to one end of the first heat dissipation channel 11. The second plug 8 is fixed to the other end of the first heat dissipation channel 11. The first heat dissipation channel 11 forms a closed flow channel through the first plug 7 and the second plug 8. The second fluid is arranged in the first heat dissipation channel 11, and the second fluid can flow relative to the first heat dissipation channel 11. In other words, the second fluid does not fill the entire first heat dissipation channel 11, so that the second fluid can flow in the first heat dissipation channel 11, thereby improving the heat dissipation efficiency and enhancing the heat dissipation effect, while also preventing the second fluid from expanding and damaging the radiator 100.

[0052] In some embodiments, a portion of the first plug 7 is received in the first receiving groove 13 so that the first plug 7 does not protrude from the first receiving groove 13, and a portion of the second plug 8 is received in the second receiving groove 14 so that the second plug 8 does not protrude from the second receiving groove 14. The first receiving groove 13 and the second receiving groove 14 reduce the space occupied by the heat sink 100.

[0053] In some embodiments, the second fluid may be a cooling medium such as coolant or cooling oil.

[0054] It is understandable that, in some embodiments, in order to improve the heat dissipation efficiency and enhance the heat dissipation effect, the heat sink 100 includes a plurality of first plugs 7 and a plurality of second plugs 8 as well as a flow concentrator 5 .

[0055] In an embodiment of the present invention, a heat sink 100 includes a base plate 1 and a plurality of heat sink fins 2. The base plate 1 is provided with a plurality of first heat dissipation channels 11, which are arranged at intervals. The plurality of heat sink fins 2 are fixed to a surface of the base plate 1 at intervals, and second heat dissipation channels 3 are formed between adjacent heat sinks 2. The provision of first heat dissipation channels 11 on the base plate 1 increases the number of heat dissipation channels of the heat sink 100, thereby increasing the heat dissipation area of the heat sink 100 and improving the heat dissipation efficiency of the heat sink 100.

[0056] The present invention further provides a motorcycle embodiment, the motorcycle including the above-mentioned radiator 100. The structure and function of the radiator 100 can be referred to the above-mentioned embodiment and will not be described in detail here.
