TECHNICAL FIELD

[0002] The prior art CN216342423U discloses a motorcycle engine high-efficiency heat dissipation device, which proposes a motorcycle engine body, a shell is sleeved on the surface of the motorcycle engine and corresponds to the position of the heat dissipation fins, a vortex cooler is fixedly installed on one side of the inner cavity of the shell, and a connecting mechanism is connected to the cold air end of the vortex cooler;Through the setting of the vortex cooler, air compressor and connecting mechanism, external air is sucked by the air compressor, compressed, and then discharged into the vortex cooler through the air inlet of the vortex cooler, and the compressed air is discharged through the connecting mechanism after conversion in the vortex cooler, so that the motorcycle engine and the heat dissipation fins are rapidly cooled, and the motorcycle engine is prevented from being forced to stop and cool due to poor heat dissipation, thereby affecting the travel distance and ensuring the service life of the motorcycle engine.

[0003] The above-mentioned scheme and prior art can dissipate heat when the motorcycle engine is cooled, but the existing off-road water-cooled motorcycle engine may encounter a sudden increase in heat that cannot be dissipated by the water-cooled radiator when working at low speed and climbing, and the original radiator is limited by the volume constraint of the vehicle and cannot be further enlarged. For such unexpected situations, the user can only choose to temporarily stop working, and then start after the engine is fully cooled, which will delay the normal use of the motorcycle and cannot meet the actual use requirements.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below. All other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figures 1 to 5 The utility model provides three technical schemes for a high-efficiency heat dissipation structure for a motorcycle engine.

[0023] Embodiment one: a high-efficiency heat dissipation structure for a motorcycle engine, including engine water cooling cylinder body 1, fin 2 and heat dissipation auxiliary assembly, engine water cooling cylinder body 1 mainly refers to the equipment of cooling cylinder body through water cooling mode, and its design pays more attention to lightweight, high efficiency and low noise,

[0024] The left outer side wall of the engine water cooling cylinder body 1 is provided with the fin 2, and the fin 2 is provided with six pieces, and the heat dissipation auxiliary assembly is arranged on the fin 2, the heat dissipation auxiliary assembly is used for heat dissipation work to the engine water cooling cylinder body 1, the heat dissipation sheet material is different in heat conduction performance, and according to the heat conduction performance from high to low, it is silver, copper, aluminum, steel respectively. However, if silver is used as a heat dissipation sheet, it will be too expensive, so the best solution is to use copper. Although aluminum is much cheaper, but obviously the heat conductivity is not as good as copper (about 50% of copper).

[0025] Embodiment two: on the basis of embodiment one, the heat dissipation auxiliary assembly includes first heat dissipation hole 201, second heat dissipation hole 202;The first heat dissipation hole 201 is fixedly arranged at the center position of the fin 2, and the second heat dissipation hole 202 is equidistantly arranged on both sides of the first heat dissipation hole 201.

[0026] The heat dissipation connecting block 3 is connected between every two fins 2, and the third heat dissipation hole 301 is arranged in the heat dissipation connecting block 3, and the third heat dissipation hole 301 is arranged corresponding to the first heat dissipation hole 201.

[0027] Embodiment three;On the basis of embodiment two, the inner side wall of the heat dissipation connecting block 3 is provided with a limiting groove 302, and the heat dissipation plate 4 is connected in the limiting groove 302;The outer side wall of the heat dissipation connecting block 3 is equidistantly provided with a heat dissipation block 303;The two sides of the heat dissipation plate 4 are equidistantly provided with a first connecting hole 401, and the heat dissipation plate 4 is provided with a second connecting hole 402, and the first connecting hole 401 and the second connecting hole 402 are connected through the third connecting hole 403.

[0028] When using, heat is absorbed from the fin 2 on the left side of the engine water cooling cylinder body 1 to dissipate heat, and through the cooperation between the first heat dissipation hole 201, the second heat dissipation hole 202 and the heat dissipation connecting block 3, the heat dissipation can be more effective.

[0029] The left side of the water-cooled cylinder block of the engine is designed to increase a first group of 6 pieces of radiating fins 4, which directly diffuse the heat generated during combustion of the cylinder block. This is the method used by air-cooled engines, which we borrow to use, which can effectively increase the heat dissipation efficiency of the engine. In combination with the water-cooled mechanism, they complement each other and perfectly solve the problem of heat dissipation of off-road vehicles under complex working conditions. From the installation method of water cooling, it can be divided into built-in water cooling and external water cooling. For built-in water cooling, it is mainly composed of a radiator, a water pipe, a water pump and sufficient water source, which determines that most of the water-cooled cooling system has a larger "volume" and requires sufficient space inside the machine case.

[0030] The first radiating fin 4 is selected on the left side during design. The space position outside the cylinder barrel is wide enough, which is beneficial to arrange the radiating fin. The air flow is smooth at this position, and the heat dissipation effect is best. The original engine cylinder design space is not increased. The cost is not increased, and it is simple and reliable.

[0031] The utility model relates to the circuit and mechanical connection as the usual means of the person skilled in the art, and can obtain technical inspiration through limited test, and belongs to the public common knowledge. The components not described in detail in the text are prior art.

[0032] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
