Definitions
- the invention relates to an electric motorcycle.
- An electric motorcycle is a two-wheeled vehicle that is at least partially driven by an electric motor.
- the electric motor converts the electrical energy stored in a high-voltage storage device into mechanical energy for propulsion.
- the object of the invention is to improve the heat dissipation of the electric motorcycle.
- an electric motorcycle which has a housing positioned in the front view in the middle of the motorcycle to accommodate an electric motor and / or a gearbox, an internal cooling device and / or an electronic component and two attached to opposite sides of the housing from the side of the housing comprises outwardly extending heat sinks.
- external cooling fins are arranged on the heat sinks, which extend in the longitudinal direction of the electric motorcycle, so that the heat sink and its cooling fins are in direct contact with the ambient air of the electric motorcycle.
- the cooling device and / or the electronic component is accommodated at least in sections in at least one of the cooling bodies and thermally connected to the cooling body in order to generate thermal energy of the cooling device and / or the Electronic components are released into the environment of the electric motorcycle via the heat sink.
- the invention is based on the basic idea of cooling the internal cooling device and / or electronic component to be cooled by means of two heat sinks directly through the ambient air of the electric motorcycle.
- the cooling device and / or electronic components are arranged at least in sections in at least one of the heat sinks.
- the heat sinks protrude outwards from the side of the electric motorcycle.
- the arrangement of the heat sinks means that a large area of the heat sinks is in direct contact with the ambient air, so that improved cooling is achieved, since a larger amount of thermal energy can be dissipated. Because at least a part of the cooling device and / or electronic component is arranged in heat sinks protruding laterally from the electric motorcycle, additional installation space is gained on the electric motorcycle so that a larger battery can be installed, for example.
- “being in direct contact with the ambient air of the electric motorcycle” is understood to mean that the airflow generated when the electric motorcycle is in motion flows around the heat sink. The ambient air is therefore not guided to the heat sinks via a flow channel.
- five side surfaces of the heat sink are in direct contact with the ambient air, so that a large contact area is provided between the heat sink and the ambient air.
- cooling ribs are integrally formed on the associated cooling body. In this way, good heat conduction is achieved between the heat sink and the cooling fins.
- At least some of the cooling ribs can circumferentially enclose the associated cooling body in a closed manner.
- the electronic component includes, for example, power electronics that heat up significantly during operation and / or charging electronics.
- the cooling device comprises a liquid cooler for a component of the electric motorcycle and / or a cooler for components of the electric motorcycle that are removed from the heat sink. The heat dissipation of the components to be cooled of the electric motorcycle is thus improved by the heat sink.
- the components of the electric motorcycle are the electronic component, the electric motor, the transmission and / or the battery of the electric motorcycle.
- Water, oil, glycol or a glycol-water mixture can be used as the cooling liquid for the liquid cooler.
- At least one of the heat sinks can have a cavity in which the cooling device and / or the electronic component is arranged.
- the cooling device and / or the electronic component is thus protected from external influences, for example moisture.
- internal cooling ribs protruding into the cavity can be provided on at least one cooling body.
- the internal cooling ribs in the cavity are connected directly to the cooling device and / or electronic component via flat contact. In this way, a simple structure of the heat sink is guaranteed.
- the oil can also contact the ribs directly.
- the cooling bodies and the external cooling fins comprise or consist of a light metal, preferably aluminum.
- a lightweight heat sink is thus provided, so that weight on the electric motorcycle is saved.
- aluminum has very good thermal conductivity properties.
- the heat sinks can extend in the middle or lower third of the height of the housing and end at least 50 mm apart from the upper and lower end of the housing.
- the heat sinks are preferably arranged in the lower two thirds of the housing and extend outward so far that the heat sinks do not contact the road when the electric motorcycle is in a maximum inclined position.
- the heat sinks are shorter than the housing in the longitudinal direction of the vehicle, so that additional space is created for the feet and legs of the driver of the electric motorcycle.
- the heat sinks each have a horizontal width which corresponds to at least 40% of the maximum width of the housing.
- the foot area of the driver of the electric motorcycle is thus additionally protected if the electric motorcycle tips over to the side.
- the distance of the point of each heat sink farthest from a vertical center plane of the electric motorcycle running in the vehicle longitudinal direction to the center plane of the electric motorcycle can be at least 35% and at most 50% of the total width of the electric motorcycle.
- the track width of the electric motorcycle is therefore determined by another component, for example the handlebar, and at the same time the largest possible contact surface is provided on the heat sinks for heat dissipation.
- the two heat sinks are preferably arranged in mirror image to the vertical center plane of the electric motorcycle running in the longitudinal direction of the vehicle. In this way, an uneven force of the airstream on different sides of the electric motorcycle is prevented.
- a variant of the invention provides that the electronic components are positioned in one heat sink and the liquid cooler is positioned in the other.
- the heat sink thus forms part of the liquid cooler.
- the cooler for example a cooling line, of a component removed from the heat sink in sections in the heat sink.
- FIG. 1 is a schematic front view of a housing with heat sinks from Figure 1,
- FIG. 3 is a schematic plan view of the housing with heat sinks of Figure 2
- FIG. 4 shows a section through a heat sink along the section line IV-IV in FIG.
- Figure 1 shows schematically an electric motorcycle 10 in a front view.
- the electric motorcycle 10 is a motorcycle that is at least partially, in particular completely, driven by an electric motor.
- the electric motorcycle 10 has a handlebar 12, a housing 14 to accommodate the electric motor and / or a transmission, two heat sinks 16, a front wheel 18, an internal cooling device 20 and several electronic components 22, only one of which is shown.
- the length of a component described below is the extent in the longitudinal direction of the electric motorcycle 10, that is to say in the longitudinal direction of the vehicle, in the installation position.
- the width is then the dimension of the component arranged in the horizontal, orthogonal to the longitudinal direction of the vehicle, and the height of a component is the dimension in the vertical direction.
- the handlebar 12 determines the overall width B M of the electric motorcycle 10.
- the internal cooling device 20 comprises, for example, a liquid cooler for the transmission, the electric motor or the battery of the electric motorcycle 10 and / or a cooler for the components of the electric motorcycle 10 that are removed from the heat sink.
- the electronic component 22 has power electronics and / or charging electronics of the electric motorcycle 10.
- the power electronics are, for example, an inverter that converts the DC voltage provided by the battery of the electric motorcycle 10 into an AC voltage, and / or a voltage converter that converts the high voltages (more than 60 V) of the battery into low voltages (12 V to 24 V). transferred, which is required for an electrical system of the electric motorcycle 10.
- Components of the electric motorcycle 10 such as a digital speedometer, a blinker, etc. are supplied with electrical energy by the on-board network.
- the heat sinks 16 are arranged on opposite sides of the electric motorcycle 10.
- the heat sinks 16 are arranged on opposite sides of the housing 14, so that the heat sinks 16 create a boxer silhouette for the electric motorcycle 10.
- the heat sinks 16 create an appearance like that of a motorcycle with a boxer engine, in which the cylinders are arranged on opposite sides of the motorcycle.
- the heat sinks 16 have a cavity 24 (see FIG. 4) in which the internal cooling device 20 and / or the electronic component 22 are accommodated at least in sections.
- the internal cooling device 20 is arranged at least in sections in the left heat sink 16 seen in the front view, and the electronic component 22 is arranged at least in sections in the right heat sink 16.
- External cooling ribs 26 are arranged on each of the cooling bodies 16, which extend in the longitudinal direction of the electric motorcycle 10 and encircle the respective cooling body 16 in a circumferentially closed manner.
- the cooling fins 26 are integrally formed on the associated heat sink 16, in that they together form a cast part.
- the heat sinks 16 in combination with the associated external cooling fins 26 are therefore designed as lamellar coolers.
- the heat sinks 16 and the external cooling fins 26 are made of a light metal, preferably aluminum.
- FIG. 1 it can be seen that the two laterally protruding heat sinks 16 are arranged in mirror image to a vertical center plane 28 of the electric motorcycle 10 running in the longitudinal direction of the vehicle.
- the maximum external distance 30 of the heat sinks 16 from one another is 70% to 100% of the total width BM of the electric motorcycle 10.
- the outer spacing 30 is approximately 75% of the total width BM of the electric motorcycle 10.
- the distance 32 of the point of each heat sink 16 furthest from the center plane 28 to the center plane 28 is between 35% and 50% of the total width BM of the electric motorcycle 10.
- the heat sinks 16 are designed to dissipate the thermal energy of the cooling device 20 and the electronic component 22 to the surroundings of the electric motorcycle 10.
- the left heat sink 16 is in thermal contact with the cooling device 20 and the right heat sink 16 is in thermal and physical contact with the electronic component 22, so that the thermal energy of the cooling device 20 and / or the electronic component 22 is transmitted to the heat sink 16 and the corresponding cooling fins 26 .
- FIG. 2 shows the housing 14 and the arrangement of the heat sinks 16 on the housing 14 in the front view of FIG.
- Heat sinks 16 designed as one-piece bodies are attached to opposite sides of the housing 14.
- the maximum height H G and the maximum width B G of the housing 14 and the width BK of a heat sink 16 are shown in FIG.
- the width BK of the heat sink corresponds to approximately 50% of the width B G of the housing 14.
- the width BK of the heat sink 16 is at least 40% of the width B G of the housing 14.
- the heat sinks 16 are attached laterally to the housing 14 in the vertical at least for the most part, preferably completely in the middle third 34.
- two auxiliary lines 36 are drawn in, which subdivide the housing 14 at the height H G into three equal parts.
- the heat sink 16 can also be arranged in the lower third or in the lower two thirds of the housing 14 or can extend there.
- the heat sinks 16 are at a distance A from the upper and lower ends of the housing 14 which is at least 50 mm.
- the distances A to the top and bottom of the housing 14 are the same. In general, of course, these can be different.
- FIG. 3 shows the housing 14 and the heat sinks 16 in a plan view.
- the length LK of the heat sinks 16 and the length L G of the housing 14 are also shown.
- FIG. 4 shows a section along the section line IV-IV in FIG. 3 through the left heat sink 16.
