Detailed Description

In order to make the present utility model better understood by those skilled in the art, the technical solutions in the specific embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1, the present application provides a motorcycle 100 that includes a frame 11, a power system 12, a cooling system 13, and a running gear 14. The frame 11 constitutes the basic frame of the motorcycle 100, and the power system 12 is provided on the frame 11, the power system 12 including a driving device 121 for driving the motorcycle 100. The travel assembly 14 is at least partially coupled to the power system 12 for propelling the motorcycle 100. The cooling system 13 is partly connected to the power system 12, the cooling system 13 enabling the drive means 121 to be at a suitable operating temperature. The motorcycle referred to in this embodiment should not be interpreted as a motorcycle as shown in fig. 1 in a narrow sense. The motorcycle referred to in this embodiment should also include a motorcycle divided based on wheels of the motorcycle, and specifically may be a two-wheeled motorcycle including only one front wheel and one rear wheel, a motor tricycle including one front wheel and two rear wheels, a motor tricycle including two front wheels and one rear wheel, or a four-wheeled motorcycle including two front wheels and two rear wheels. It should be noted that there are various ways of classifying motorcycles at present, in some of which the classification will be made in parallel with the motorcycle, not being considered as a general motorcycle, and in other of which the classification is considered as a specific type of motorcycle, mainly considering whether the concept of a motorcycle is understood narrowly or in a broad sense.

As shown in fig. 2 and 3, the cooling system 13 includes a heat dissipating device 131, and the heat dissipating device 131 is connected to the driving device 121 through a pipe. When the driving device 121 is in operation, the high-temperature cooling liquid generated by the driving device 1211 is discharged into the heat dissipating device 131, the high-temperature cooling liquid circulates in the heat dissipating device 131 and is cooled down, and the cooling liquid cooled down in the heat dissipating device 131 is then fed into the driving device 121 to cool down the driving device 121. Specifically, the heat dissipating device 131 includes a first heat sink 1311, a second heat sink 1312, and a third heat sink 1313, and the first heat sink 1311, the second heat sink 1312, and the third heat sink 1313 are connected by a pipe. The first radiator 1311, the second radiator 1312, and the third radiator 1313 are disposed close to the power system 12, so that the distances of the heat dissipation pipes between the first radiator 1311, the second radiator 1312, the third radiator 1313, and the driving device 121 can be reduced, and the heat dissipation efficiency can be increased. Defining a longitudinal center plane 101 perpendicular to the width direction of the motorcycle 100, the motorcycle 100 being substantially symmetrical about the longitudinal center plane 101, the second heat sink 1312 being provided on one side of the longitudinal center plane 101, the third heat sink 1313 being provided on the other side of the longitudinal center plane 101, at least portions of the second heat sink 1312 and the third heat sink 1313 coinciding with the driving device 121 as seen in the width direction of the motorcycle 100. The first heat sink 1311 is provided at the front of the driving device 121, and the first heat sink 1311 is provided between the second heat sink 1312 and the third heat sink 1313. The above arrangement increases the contact area between the coolant and the air by increasing the number of the heat sinks in the heat sink 131, thereby improving the heat dissipation efficiency of the heat sink 131. Thus, the power drop caused by the excessively high temperature of the driving device 121 can be avoided, the operation stability of the driving device 121 can be improved, and the working efficiency of the driving device 121 can be improved. In general, at least part of the heat dissipating device 131 may be disposed at the front of the driving device 121, and in particular, the first heat sink 1311 in the heat dissipating device 131 is generally disposed at the front of the driving device 121, so that the heat dissipating efficiency of the whole heat dissipating device 131 can be enhanced, and the structural compactness of the whole motorcycle 100 can be improved.

As an embodiment, as shown in fig. 3, the second heat spreader 1312 and the third heat spreader 1313 are symmetrically arranged about the longitudinal center plane 101. The symmetrical arrangement of the second radiator 1312 and the third radiator 1313 can ensure that the second radiator 1312 and the third radiator 1313 basically maintain a balanced state, thereby improving the distribution uniformity of the overall weight of the motorcycle 100. Meanwhile, the cooling liquid can be uniformly radiated in the second radiator 1312 and the third radiator 1313, so that the balanced radiation of the driving device 121 is facilitated, and the driving device 121 is prevented from being damaged due to local overheating. The heat dissipation effect of the heat dissipation device 131 can be increased, and the service life of the whole driving device 121 can be prolonged.

As an embodiment, as shown in fig. 3, the maximum length L of the heat sink 131 in the width direction of the motorcycle 100 is 455mm or more and 845mm or less. The size of the heat dissipating device 131 is within the above range, so that the contact area between the cooling liquid and the air and the heat dissipating requirement can be satisfied, and the unreasonable occupation of the vehicle space by the heat dissipating device 131 when the maximum length L occupied in the width direction of the motorcycle 100 is too large can be avoided.

As one embodiment, as shown in fig. 3, the first heat sink 1311 is provided in an arc shape. The arcuate design can increase the surface area of the first radiator 1311 without increasing the width of the first radiator in the width direction of the motorcycle 100, further improving the cooling efficiency of the first radiator 1311. The internal structure of the motorcycle 100 is also made more compact, and the overall space utilization is improved.

As an embodiment, as shown in fig. 3 and 4, the heat dissipating device 131 includes a first fan 1314, a second fan 1315, and a third fan 1316, the first fan 1314 is disposed on one side of the first heat sink 1311, the second fan 1315 is disposed on one side of the second heat sink 1312, and the third fan 1316 is disposed on one side of the third heat sink 1313. The fan can drive the air around the radiator to flow, so that the air flow rate is increased, and the heat generated in the radiator is taken away by the air flow to radiate the cooling liquid, so that the cooling efficiency of the radiating device 131 is greatly improved. The first fan 1314 is integrally disposed with the first heat sink 1311, the second fan 1315 is integrally disposed with the second heat sink 1312, and the third fan 1316 is integrally disposed with the third heat sink 1313. The space occupied by the radiator and the fan is reduced, and the space utilization of the motorcycle 100 is improved. As an embodiment, a transverse plane 102 perpendicular to the longitudinal direction of the motorcycle 100 is defined, and an angle α between the plane 103 in which the first radiator 1311 is located and the transverse plane 102 is 60 ° or more and 90 ° or less as shown in fig. 4. Further, an included angle α between the plane 103 in which the first heat sink 1311 is located and the lateral plane 102 is 68 ° or more and 90 ° or less. Further, an included angle α between the plane 103 where the first heat spreader 1311 is located and the lateral plane 102 is 77 ° or more and 90 ° or less. The first radiator 1311 is inclined to form a certain angle with the transverse plane 102, so that the first fan 1314 can more conveniently drive the air circulation of the first radiator 1311, and the better the air circulation effect is, the stronger the heat dissipation effect is. As shown in fig. 5, an included angle β between the plane 104 where the second heat sink 1312 is located and the longitudinal center plane 101 is 0 ° or more and 30 ° or less. Further, an included angle β between the plane 104 where the second heat sink 1312 is located and the longitudinal center plane 101 is 0 ° or more and 28 ° or less. Further, an included angle β between the plane 104 where the second heat sink 1312 is located and the longitudinal center plane 101 is 0 ° or more and 25 ° or less. The angle formed between the second radiator 1312 and the longitudinal center plane 101 can increase the windward area of the second radiator 1312, and increase the airflow speed and flow rate on the surface of the second radiator 1312, so as to accelerate the heat dissipation process of the second radiator 1312, and improve the overall working efficiency and heat dissipation effect of the heat dissipation device 131. As shown in fig. 6, an included angle γ between the plane 104 where the second heat sink 1312 is located and the lateral plane 102 is 60 ° or more and 90 ° or less. Further, an included angle γ between the plane 104 where the second heat sink 1312 is located and the lateral plane 102 is 68 ° or more and 90 ° or less. Further, an included angle γ between the plane 104 where the second heat sink 1312 is located and the lateral plane 102 is 77 ° or more and 90 ° or less. The above arrangement can make the air flow more uniformly distributed on the surface of the second radiator 1312, reduce thermal resistance and air flow dead angle, and further improve heat dissipation efficiency. In addition, by defining the ranges of the included angle α, the included angle β, and the included angle γ, it is possible to avoid the occupation space of the first radiator 1311 and the second radiator 1312 in the length, width, or height directions of the motorcycle 100 from becoming excessively large, encroaching on the installation space of other components in the motorcycle 100. Meanwhile, the phenomenon that the air circulation effect is poor due to the fact that the windward areas of the first radiator 1311 and the second radiator 1312 are too small can be avoided, and the cooling performance of the motorcycle 100 is enhanced, so that the normal operation of the driving device 121 and the safe running of the motorcycle 100 are ensured. As an embodiment, as shown in fig. 7, the second radiator 1312 and the third radiator 1313 are connected in parallel by a pipe, and connected in series with the first radiator 1311 and the driving device 121 by a pipe. It will be appreciated that the water outlet of the driving device 121 is connected to the second heat sink 1312 and the third heat sink 1313 through one tee 1317, and the water outlet of the first heat sink 1311 is connected to the second heat sink 1312 and the third heat sink 1313 through another tee 1317. When the driving device 121 works, the cooling liquid enters the second radiator 1312 and the third radiator 1313 from the water outlet of the driving device 121 through one tee 1317, after the cooling liquid completes heat exchange in the second radiator 1312 and the third radiator 1313, the cooling liquid enters the first radiator 1311 through the other tee 1317, and finally the cooling liquid flows back into the driving device 121 through the first radiator 1311. Through the arrangement, on one hand, the pipelines connected between the radiators can be reduced, and the manufacturing and maintenance difficulties of the radiating device 131 are reduced. On the other hand, the cooling liquid enters the first radiator 1311 from the same three-way piece 1317, so that the flow resistance of the cooling liquid can be reduced, the flow rate of the cooling liquid is improved, and the overall heat dissipation efficiency of the heat dissipation device 131 is enhanced.

As an embodiment, as shown in fig. 8, the second radiator 1312 and the third radiator 1313 are connected in series through a pipe, and connected in parallel with the first radiator 1311 through a pipe, and the driving device 121 is connected in series with the first radiator 1311. It will be appreciated that the water outlet of the drive 121 is connected to the first heat sink 1311 and the second heat sink 1312 via a tee 1317. The water inlet of the driving device 121 is connected to the first radiator 1311 and the third radiator 1313 through another tee 1317. When the driving device 121 is in operation, the cooling liquid enters the first radiator 1311 and the second radiator 1312 from the water outlet of the driving device 121 through a tee 1317. The cooling liquid in the first radiator 1311 flows back to the driving device 121 directly through the other three-way member 1317 after the circulation is completed. The cooling liquid in the second radiator 1312 enters the third radiator 1313, and after circulation, returns to the driving device 121 through the other tee 1317. A cooling circuit is formed between the first radiator 1311 and the driving device 121, and a cooling circuit is formed between the second radiator 1311, the third radiator 1313 and the driving device 121. When any cooling loop fails, normal operation of other cooling loops is not affected, and therefore modularization of the heat dissipating device 131 is facilitated, and maintenance cost of the heat dissipating device 131 is reduced.

As one embodiment, the heat dissipating device 131 includes at least two first heat sinks 1311, and the adjacent two first heat sinks 1311 overlap at least partially in the longitudinal direction of the motorcycle 100. In the case of a high power drive 121, the plurality of heat sinks are kept in operation to ensure that the drive 121 reaches a good operating temperature. Thereby avoiding the damage of the driving device 121 due to the long-time high temperature state, prolonging the service life of the driving device 121 and improving the stability of the motorcycle 100. Specifically, the plurality of first heat sinks 1311 may be provided in a stack. With the above arrangement, the contact area between the first radiator 1311 and the air can be increased, and the heat radiation efficiency of the heat radiation device 131 can be further enhanced.

As an embodiment, the driving device 121 may be an engine or a motor. The heat dissipation device 131 can meet the heat dissipation requirement of the driving device 121 under different powers, and the heat dissipation device 131 can meet the heat dissipation requirement of an engine in a fuel motorcycle and the heat dissipation requirement of a motor in an electric motorcycle. The heat dissipating device 131 of the present application has a wide application range.
