[0002] Since motorcycle engines generally require a radiator to dissipate heat, the radiator's heat dissipation capacity plays an important role in engine performance. Large-displacement motorcycles have a compact structure and complex layout, so it is particularly important to improve the radiator's heat exchange capacity in a limited space. The existing radiator's heat dissipation circulation pipes are flat pipes. In order to increase the heat dissipation capacity, the number of flat pipes needs to be increased, which requires a larger space and requires matching a larger motor and fan, thus significantly increasing the cost of the motorcycle.
[0003] In summary, how to reduce the production cost of motorcycles is an urgent problem to be solved by those skilled in the art. Summary of the Invention
[0004] In view of this, the purpose of the present invention is to provide a water-cooled radiator, in which a variable-section channel tube is provided with multiple channels, and the internal channels can circulate with each other, causing a strong disturbance effect on the fluid in the tube and improving the heat dissipation efficiency.
[0005] Another object of the present invention is to provide a motorcycle comprising the water-cooled radiator.
[0006] In order to achieve the above object, the present invention provides the following technical solutions:
[0007] A water-cooled radiator is used to be arranged between a left water chamber and a right water chamber of an engine, and the water-cooled radiator comprises:

[0010] Preferably, the first channel and the third channel are symmetrically arranged with respect to the second channel, and the cross-sectional area of the second channel is larger than the cross-sectional area of the first channel.
[0011] Preferably, there are multiple flat tube segments and multiple variable-section channel tubes, and the flat tube segments and the variable-section channel tubes are arranged at intervals and connected to form a heat dissipation circulation tube. Each heat dissipation circulation tube includes at least 10 flat tube segments and at least 10 variable-section channel tubes.
[0012] Preferably, a heat dissipation belt is provided between two adjacent heat dissipation circulation tubes, and the heat dissipation circulation tubes located at the uppermost end and the lowermost end are provided on a baffle.
[0013] Preferably, a fan is further included, and the fan is arranged opposite to the heat dissipation circulation pipe, and the fan is used to improve the heat dissipation efficiency of the heat dissipation circulation pipe.
[0014] Preferably, the heat dissipation circulation pipe is arranged between the left main piece and the right main piece, and the left main piece and the right main piece are further provided with a guide ridge plate and a fan guide cover.

The second channel is arranged between the first channel and the third channel. Perforations are provided on the side walls of the first channel, the second channel, and the third channel, so that the first channel and the second channel are connected, and the second channel and the third channel are connected. When fluid enters the flat tube section from the left water chamber or the right water chamber, it can be passed into the variable-section channel tube. Due to the internal connection between the first channel, the second channel, and the third channel, a strong disturbance effect is caused on the fluid in the tube.

[0028] The core of the present invention is to provide a water-cooled radiator, in which a plurality of interconnected channels are provided in a variable-section channel tube. When the fluid flows, it can cause a strong disturbance effect on the fluid in the tube, and the heat exchange with the tube wall area is more sufficient, thereby improving the heat exchange capacity of the radiator and reducing the production cost of the motorcycle.
[0029] Another core of the present invention is to provide a motorcycle comprising the above-mentioned water-cooled radiator.
[0030] It should be noted that the directions or positional relationships indicated by “upper”, “lower”, “front”, “back”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application.
[0031] The present application provides a water-cooling radiator, which is used to be arranged between the left water chamber and the right water chamber of the engine. The water-cooling radiator includes: a flat tube section 1 and a variable-section channel tube 2;
[0032] The flat tube section 1 is connected to the left water chamber or the right water chamber;
[0033] The variable-section channel tube 2 is connected to the flat tube section 1. A first channel 201, a second channel 202 and a third channel 203 are arranged in parallel in the variable-section channel tube 2. The second channel 202 is arranged between the first channel 201 and the third channel 203. The side walls of the first channel 201 and the second channel 202 are connected through perforations, and the side walls of the second channel 202 and the third channel 203 are connected through perforations.
[0034] For details, please refer to the attached Figure 1 With attached Figure 2 The water-cooled radiator is arranged between the left water chamber and the right water chamber, and the two ends of the water-cooled radiator are respectively connected to the left water chamber and the right water chamber. The flat tube section 1 is connected to at least one of the left water chamber or the right water chamber. The other end of the flat tube section 1 is connected to the variable-section channel tube 2. The interior of the variable-section channel tube 2 is provided with a first channel 201, a second channel 202 and a third channel 203. The three channels can divide the internal channel of the variable-section channel tube 2 into three parts. The second channel 202 is arranged between the first channel 201 and the third channel 203. Corresponding perforations are provided on the side walls of the first channel 201, the second channel 202 and the third channel 203. The positions of the perforations can be irregular. Distribution, so that the first channel 201, the second channel 202 and the third channel 203 can be connected in sequence. When the fluid enters the flat tube section 1, it flows into the variable-section channel tube 2 through the flat tube section 1. After the fluid enters the variable-section channel tube 2, it is divided into three parts and enters the first channel 201, the second channel 202 and the third channel 203 respectively. Since the first channel 201, the second channel 202 and the third channel 203 are connected in sequence through the perforations, it is convenient for the fluid in the tube to circulate with each other, causing a strong disturbance effect on the fluid in the tube, thereby improving the heat exchange capacity of the radiator itself. On the other hand, it can adjust the local pressure of each channel and effectively improve the uniformity of fluid flow distribution.
[0035] On the basis of the above embodiment, the first channel 201 and the third channel 203 are symmetrically arranged with respect to the second channel 202 , and the cross-sectional area of the second channel 202 is larger than that of the first channel 201 .
[0036] Specifically, please refer to the attached Figure 1The cross-sectional areas of the first channel 201 and the third channel 203 are the same, the cross-sectional area of the second channel 202 is larger than that of the first channel 201, and the second channel 202 is a convergent tube. Compared with the flat tube, when the flow area is the same, the contact surface between the convergent tube and the heat dissipation belt will be wider, thereby increasing the heat exchange capacity.
[0037] Based on the above embodiments, multiple flat tube segments 1 and variable-section channel tubes 2 are provided, and the flat tube segments 1 and variable-section channel tubes 2 are arranged at intervals and connected to form a heat dissipation circulation tube. Each heat dissipation circulation tube includes at least 10 flat tube segments 1 and at least 10 variable-section channel tubes 2.
[0038] For details, please refer to the attached Figure 2 Flat tube segments 1 and variable-section channel tubes 2 are arranged alternately to form the heat dissipation circulation tubes. Each heat dissipation circulation tube is terminated by a flat tube segment 1, connecting the heat dissipation circulation tube to the left and right water chambers. The alternating arrangement of flat tube segments 1 and variable-section channel tubes 2 reduces the temperature gradient of the fluid flowing within the radiator tubes, enhancing the radiator's heat exchange capacity. Furthermore, to better disturb the fluid within the tubes and enhance the radiator's heat transfer, the optimal number of alternating flat tube segments 1 and variable-section channel tubes 2 is 10-15.
[0039] On the basis of the above embodiment, a heat dissipation belt is provided between two adjacent heat dissipation circulation tubes, and the heat dissipation circulation tubes at the uppermost end and the lowermost end are provided on the baffle.
[0040] For details, please refer to the attached Figure 2 Multiple heat dissipation circulation tubes are arranged parallel to each other. The heat dissipation circulation tubes at the top and bottom are set on the baffle, which can play a limiting role. A heat dissipation belt is set between two adjacent heat dissipation circulation tubes. The heat dissipation belt can quickly take away the heat transferred from the fluid medium to the heat dissipation circulation tube, thereby achieving the goal of efficient heat dissipation.
[0041] On the basis of the above embodiment, a fan is further included. The fan is arranged opposite to the heat dissipation circulation pipe, and the fan is used to improve the heat dissipation efficiency of the heat dissipation circulation pipe.
[0042] Specifically, a fan is provided at a position directly opposite the heat dissipation circulation tube, which blows directly on the heat dissipation circulation tube, driving the heat to be transferred into the air, thereby increasing the air flow on the surface of the heat dissipation circulation tube to improve the heat dissipation efficiency of the heat dissipation circulation tube.
[0043] On the basis of the above embodiment, the heat dissipation circulation pipe is arranged between the left main piece and the right main piece, and the left main piece and the right main piece are further provided with a guide ridge plate 3 and a fan guide cover 4.
[0044] For details, please refer to the attached Figure 3The heat dissipation circulation pipe is embedded in the left and right main pieces, wherein the main pieces are connected to the left and right water chambers. The new heat dissipation circulation pipe is limited by baffles at the top and bottom. The new heat dissipation circulation pipe is composed of heat dissipation belts arranged in a staggered manner. A fan guide cover 4 is set on the back of the fan. At the same time, 8 guide ridges 3 are designed on the motor, wherein the guide ridges 3 are staggered between the blades of the fan, so that when the fan is turned on, it can better dissipate heat and also prevent hot air from blowing onto people.
[0045] On the basis of the above embodiment, it further includes a water inlet pipe 5 and a water outlet pipe 6, the water inlet pipe 5 is connected to the left water chamber, and the water outlet pipe 6 is connected to the right water chamber;
[0046] Alternatively, the water inlet pipe 5 is connected to the right water chamber, and the water outlet pipe 6 is connected to the left water chamber.
[0047] For details, please refer to the attached Figure 3 The water inlet pipe 5 and the water outlet pipe 6 are embedded between the left water chamber and the right water chamber. The water inlet pipe 5 and the water outlet pipe 6 are respectively connected to the engine pipeline to realize the water circulation loop.
[0048] On the basis of the above embodiment, both the water inlet pipe 5 and the water outlet pipe 6 are provided with limiting protrusions 7 .
[0049] Specifically, a limiting protrusion 7 is provided on the water inlet pipe 5 and the water outlet pipe 6. On the one hand, it is a seal that isolates the seal from the water chamber. On the other hand, the water inlet pipe 5 and the water outlet pipe 6 are respectively connected to the engine pipeline, which plays a limiting and sealing role to avoid water leakage at the connection between the engine and the radiator. The length of the straight section between the two limiting protrusions 7 is limited to 32-40mm, so that when the other layouts are compact, the straight section can be bent to ensure the roundness of the section.
[0050] In some embodiments, the second channel 202 is a converging tube.
[0051] Specifically, the cross-sectional area of the second channel 202 is larger than that of the first channel 201 , and the second channel 202 is a convergent tube. Compared with a flat tube, when having the same flow area, the contact surface between the convergent tube and the heat dissipation belt is wider, thereby increasing the heat exchange capacity.
[0052] The above-mentioned water cooling radiator is in use in two situations:
[0053] When the motorcycle is running at high speed, Figure 2As can be seen, since the new heat dissipation circulation tube is provided with three channels, the flat tube sections 1 and the variable-section channel tubes 2 are arranged in an interlaced manner, and a perforation is provided between the first channel 201 and the third channel 203, with the multiple holes positioned at different positions. When the fluid in the tube enters the heat dissipation circulation tube, due to the cross-sectional design, the fluid preferentially flows through the second channel 202 and then flows through the perforation into the first channel 201. The mutual circulation of the fluids in the three-channel tubes enhances the heat exchange capacity of the radiator itself. Therefore, under the same heat exchange conditions, fewer heat dissipation circulation tubes of the present application can be used, saving space, and the fan does not need to be turned on.
[0054] When the motorcycle is idling or running at low speed, the heat dissipation capacity of the radiator itself is not enough to dissipate the heat of the engine. At this time, the fan is turned on. The fan guide cover 4 and the guide ridge plate 3 are provided to guide the flow, thereby avoiding heat damage. The heat generated by the engine is taken away by the external factors of the fan and the internal structure of the radiator.
[0055] In summary, the present application provides a water-cooled radiator comprising a flat tube segment 1 and a variable-section channel tube 2. The variable-section channel tube 2 is provided with three channels that can flow through each other. To facilitate on-site assembly, the new heat dissipation circulation tube has a similar appearance to conventional flat tubes. The flat tube segments 1 and variable-section channel tubes 2 are staggered to adjust the local pressure in each channel, effectively improving the uniformity of fluid flow distribution. The alternating arrangement of the flat tube segments 1 and variable-section channel tubes 2 reduces the temperature gradient of the fluid flowing within the radiator tubes. To better disturb the fluid within the tubes and enhance the radiator's heat transfer, the number of staggered heat dissipation circulation tubes is preferably approximately 10-15. To prevent water leakage caused by unstable connections between the radiator's water inlet and outlet pipes 5 and 6 and the engine water pipes, stopper protrusions 7 are designed on the radiator's water inlet and outlet pipes 5 and 6 to provide a stopper. The distance between the stopper protrusion 7 and the radiator water chamber should be 32-40 mm, ensuring that the straight segments are curved and rounded. To enhance the radiator's cooling efficiency, a fan shroud 4 is installed on the back of the fan. Eight guide ridges 3 are designed on the motor. These ridges are staggered between the fan blades, allowing for better heat dissipation when the fan is on, while also preventing hot air from blowing towards people. The water-cooled radiator's structure, through its integrated internal and external design, enhances the heat transfer capability of the new cooling circulation tube. The fan shroud and guide ridges also enhance the radiator's cooling capacity when the fan is on.
[0056] In addition to the above-mentioned water-cooled radiator, the present invention also provides a motorcycle including the water-cooled radiator disclosed in the above-mentioned embodiment. For the structures of other parts of the motorcycle, please refer to the prior art and will not be described in detail herein.
[0057] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
