Description
Technical field
The present invention relates to a kind of cooling system and application thereof of power plant, particularly a kind of motor boiling type constituent and motor.
Background technique
Motor is conventional power plant, because motor is typical heat engine, operationally can produce more heat, if these heats distribute not in time, understands rapid accumulation and causes engine breakdown, even occurring security incident.In prior art, for solving engine radiating problem, usually adopt air-cooled and cooling by water motor, to prevent gathering of heat; Wherein water-cooled has the high and stable feature of cooling effectiveness, and the problem of engine overheat can not occur; For the motor of slightly small displacement, if employing water cooled engine, then more employing motor boiling type water cooling system structure, namely direct engine cylinder-body to be cooled by cooling jacket, cooling jacket is provided with the hole for exhaust pressure relief, during engine operation, heating makes the cooling water in cooling jacket seethe with excitement and take away heat, and after cooling water boiling, temperature can not promote and reach effective cooling.
Although above-mentioned boiling type cooling structure reaches certain cooling effect, but, due to the existence of cooling jacket, have impact on the layout of motor associated components, such as, for underneath cam type engine, lower shake-changing arm is positioned at cooling jacket, corrosion is formed to lower shake-changing arm assembly, affects the normal operation of working life and motor; In addition, in the area that weather is colder, the cooling water in the cooling jacket of boiling type water-cooled engine is colder before activation, is with too much heat away, the thermal efficiency low, causes engine start initial stage power drop after startup; Meanwhile, pure motor boiling type constituent cylinder body is in subzero and when not starting in winter, and the cooling water in water jacket can freezing and expansion, and the crack damage of cylinder body even can be caused at motor.
Based on the problems referred to above, need to improve motor boiling type constituent, lower shake-changing arm can be avoided structure to be dipped in cooling water, avoid occurring corroding and affect the problem of life-span and running precision, further, there will not be under colder environment and affect engine thermal efficiency and freezing and expansion problem.
Summary of the invention
In view of this, the invention provides a kind of motor boiling type constituent and motor, lower shake-changing arm can be avoided structure to be dipped in cooling water, avoid occurring corroding and affect the problem of life-span and running precision, further, there will not be under colder environment and affect engine thermal efficiency and freezing and expansion problem.
Motor boiling type constituent of the present invention, comprise water tank and be positioned at engine cylinder external body and surround the cooling jacket of engine cylinder-body, the end cap that described cooling jacket comprises body and is tightly connected with body, described body rear and front end opening, described end cap comprises the front cover that be tightly connected corresponding to the opening of body rear and front end and rear end cover respectively, and described cooling jacket is provided with the water intake and relief opening that are communicated with water tank.
Further, described body internal surface forms radiating fin I, radiating fin I increases the heat exchange area of cylinder body and cooling water, improve refrigeration and radiating efficiency, meanwhile, remove front cover and rear end cover at comparatively cold season joint, after vehicle, radiating fin I is formed air-cooled and can meet requirement of freezing after contacting with cold wind, there will not be the problem significantly affecting engine thermal efficiency, more there will not be cold lack of water freezing and expansion problem.

Further, the cover external surface of described cooling jacket forms radiating fin II, during normal use, the body conduction of the heat of cooling water by cooling jacket can come and outwardly dispel the heat by radiating fin II, increase the radiating effect of cooling water, reduce cooling evaporation of water, extend the service time of cooling water; In the winter time, when adopting air-cooled, the heat diffusion area of the body of cooling jacket can be increased, and fully the heat that radiating fin I transmits be distributed, ensure the normal operation of motor.
Further, described radiating fin I is multiple and vertically and column distribution, structure is simple, is easy to manufacture, ensures radiating effect.
Further, radiating fin I is the sheet of level and parallel each other, after front cover of dismantling, rear end cover, enables that cooling air is smooth and easy to be passed through, ensures do not adopt cooling water and directly adopt air-cooled cooling effect; The cover body by integral forming of engine cylinder-body, radiating fin I and cooling jacket; Integrally formed structure is easily manufactured, meanwhile, be beneficial to and dispel the heat and increase the join strength of the body of cylinder body, radiating fin I and cooling jacket, certainly, can leave for the gap by cooling water after installing between front and rear cover and radiating fin I, not repeat them here.
Further, be provided with independently for the lower shake-changing arm installation position by lower shake-changing arm assembly in the body of described cooling jacket, have before and after end cap is positioned at instead of left and right, there is the condition of rocking arm installation position and cooling water space being separated, avoid rocker arm assembly directly contact with cooling water and cause adverse effect.
Further, the one-body molded body being formed at cooling jacket in described lower shake-changing arm installation position, by casting direct forming, also can split type direct installation, all can realize goal of the invention; Directly be cast as one, be beneficial to manufacture and cost-saving.
Further, the distributing position of described radiating fin II is relative with the distributing position one_to_one corresponding of radiating fin I, and radiating fin II and radiating fin I all one-body molded, the body of further increase cooling jacket and the join strength of radiating fin I, and radiating fin I and radiating fin II heat transfer nearest, be beneficial to heat radiation.
The invention also discloses a kind of motor, described motor is provided with described motor boiling type constituent, can be used for motorcycle, comprises three-wheel, two-wheeled, beach buggy etc.
Beneficial effect of the present invention: motor boiling type constituent of the present invention, adopt opening before and after the body of cooling jacket and the structure of end cap is set, the mounting point of opening and end cap and rocker arm assembly is avoided and noiseless, possesses the condition that rocker arm assembly installation position is set at cooling jacket, thus lower shake-changing arm can be avoided structure to be dipped in cooling water, avoid occurring corroding and affect the problem of life-span and running precision; Simultaneously, because opening is positioned at front and back, when vehicle is advanced, cooling air is entered by front opening and walks heat by open rearward end elution band, adopt air-cooled under colder environment, also just avoiding to there will not be under colder environment affects engine thermal efficiency and freezing and expansion problem; Structure of the present invention is simple, compared with prior art carries out less change and solves Motor Vehicle frequently adding water at Cold Winter and putting water problem, it also avoid the freezing engine damage problem caused.
