Embodiment Construction
[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0021] Such as figure 1 , 2 As shown, a double-sided cooling plate of a high-speed boat engine cooling system has a balance shaft through hole 1a in the middle of the cooling plate body 1, and an oil cooling labyrinth 2 is provided on one surface of the cooling plate body 1. The oil-cooled labyrinth 2 is composed of an oil-cooled labyrinth cavity 2a and an oil-cooled heat dissipation rib 2b, wherein the oil-cooled labyrinth cavity 2a is provided with at least one oil-cooled heat dissipation rib 2b along the cavity extension direction of the oil-cooled labyrinth cavity 2a. In this case, the number of oil cooling ribs 2b is preferably three. The starting point of the oil cooling rib 2b is provided with a circular oil inlet 2c, and the end point of the oil cooling rib 2b is provided with a circular oil outlet 2d, and both the oil inlet 2c and the oil outlet 2d...

The invention discloses a double-side cooling plate of a high-speed yacht engine cooling system. An oil cooling labyrinth is arranged on one plate surface of a cooling plate main body, the oil cooling labyrinth consists of an oil cooling labyrinth cavity and an oil cooling heat dissipating rib, at least one line of oil cooling heat dissipating rib is arranged in the oil cooling labyrinth cavity, and the oil cooling heat dissipating rib is lower than the oil cooling labyrinth cavity; and a water cooling labyrinth is arranged on the other plate surface of the cooling plate main body, the water cooling labyrinth consists of a water cooling labyrinth cavity and a water cooling heat dissipating rib, and at least one line of water cooling heat dissipating rib is arranged in the water cooling labyrinth cavity. The double-side cooling plate comprehensively adopts the design of reducing the height of the oil cooling heat dissipating rib and increasing the water cooling labyrinth, wherein the height of the oil cooling heat dissipating rib not only can ensure the contact area of cooling oil and the oil cooling heat dissipating rib, but also can ensure the mobility of the cooling oil, so that the temperature of the cooling oil is lowered; and the cooling oil is cooled through cooling water, the temperature of the cooling oil can also be lowered in this way, and as a result, the cooling effect of the cooling oil on an engine combustion chamber is improved.
Description
technical field [0001] The invention belongs to a high-speed boat engine cooling system, in particular to a double-sided cooling plate of the high-speed boat engine cooling system. Background technique [0002] The engine is an important part of the high-speed boat, and the combustion chamber will generate a lot of heat when it works. In order to ensure the normal operation of the engine, a cooling system is currently installed on the engine. The cooling system mainly includes an outer plate, an inner plate and a cooling plate in the middle. At present, an oil-cooling labyrinth is provided on the surface of the cooling plate close to the engine side. The oil-cooling labyrinth is composed of an oil-cooling labyrinth cavity and oil-cooling ribs, wherein the oil-cooling labyrinth cavity is provided with at least An oil cooling rib, the height of the oil cooling rib is consistent with the height of the oil cooling labyrinth cavity. [0003] When the engine is working, the cool...
