The device comprises a water circulating pump (6) arranged on the outside of a single-cylinder diesel engine (3) equipped with a water tank (4) and a cooling water channel (2), a radiator (10) and a cooling fan (11). The water inlet of the water circulating pump (6) communicates with the cooling water channel (2) of the single-cylinder diesel engine (3) via a water intake pipe (5). The water outlet of the water circulating pump (6) communicates with the water inlet of the radiator (10) via a circulating water pipe (8). The water outlet of the radiator (10) communicates with the water tank (4) of the single-cylinder diesel engine (3) via a backwater pipe (1). The cooling fan (11) is arranged at the side part of the radiator (10) and the center of the cooling fan (11) coincides with the center of the radiator (10). The water circulating pump (6) is connected with a belt pulley (9) arranged on the output shaft of the single-cylinder diesel engine (3) via a belt (7). The auxiliary heat radiation device is simple in structure. By utilizing the device, the number of charging cooling water into the single-cylinder diesel engine and the power loss are reduced and the operating efficiency is improved.
Description
Technical field
The utility model relates to a kind of single cylinder diesel, particularly the sink of evaporative type single cylinder diesel.
Background technique
The cooling system of present single cylinder diesel is divided into evaporative type and follows steaming formula two big classes from the water cooling aspect, the evaporative type single cylinder diesel is the temperature that relies on temperature difference change single cylinder diesel body between cooling liquid and the engine body, it has simple in structure, be easy to maintaining, advantages of cheap price, but adopt single cylinder diesel cooling liquid evaporation when work of this kind type of cooling very fast, cause the continuous loss of cooling liquid to cause the diesel engine power loss, therefore need frequently add inject cooling liquid, make troubles to use; Compare with the evaporative type single cylinder diesel and follow steaming formula single cylinder diesel,, complex structure is arranged also, cost an arm and a leg the shortcoming that power ascension is slow though have the few advantage of cooling liquid filling number of times.
The model utility content
At the above-mentioned defective that exists in the prior art, it is a kind of simple in structure that the utility model provides, and can reduce the number of times that single cylinder diesel adds inject cooling liquid, reduces its power loss, improves the auxiliary radiating device of its working efficiency.
The utility model is achieved by the following technical solution: the auxiliary radiating device of single cylinder diesel, comprise be arranged on have water tank, circulating water pump, radiator and the cooling fan of the single cylinder diesel outside of cooling water channel, the water intake of described circulating water pump is communicated with the cooling water channel of single cylinder diesel by intake pipe, its water outlet is communicated with the water intake of described radiator by circulating pipe, and the water outlet of radiator is communicated with the water tank of single cylinder diesel by return pipe; Cooling fan is arranged on the radiator side, and the center of its center and radiator coincides; Circulating water pump is connected with belt pulley on being located at the single cylinder diesel output shaft by belt.
In single cylinder diesel when work,, circulating water pump obtains power by being connected belt pulley on the single cylinder diesel output shaft and the belt between the circulating water pump from single cylinder diesel.Cooling liquid is by the flow through cooling water channel of single cylinder diesel of water tank, and heat absorption back temperature raises, and by being connected the intake pipe between cooling water channel and the circulating water pump water intake, flow into circulating water pump; In circulating water pump, cooling liquid obtains supercharging, and the cooling liquid after the supercharging enters in the radiator by circulating pipe again; In radiator, cooling liquid is lowered the temperature to flowing through the heat radiation of radiator ambient air; At last, cooled cooling liquid flow back in the water tank of single cylinder diesel by the return pipe that is connected between radiator and the single cylinder diesel water tank, and so circulation endlessly.In cooling fan when work,, air high speed flow mistake around the radiator is to strengthen the cooling to cooling liquid.In the single cylinder diesel working procedure, liquid circulation flows, thereby reaches the operating temperature that reduces single cylinder diesel, the purpose that improves its working efficiency.
In order to improve the radiating effect of radiator, the distance between cooling fan and the radiator is: 30mm～100mm.
The beneficial effects of the utility model are, because independent auxiliary radiating device is set outside single cylinder diesel, take away the heat that diesel engine produces by radiator, can not only effectively reduce the operating temperature of single cylinder diesel, and the cooling water loss is few, can significantly reduce the number of times of filling cooling water, reduce the power loss of diesel engine, improve the working efficiency of single cylinder diesel.The utility model is simple in structure, is easy to maintaining.

Embodiment
Embodiment below by indefiniteness also is further described the utility model in conjunction with the accompanying drawings:
As shown in drawings, single cylinder diesel 3 is the evaporative type single cylinder diesel, and it has cooling water channel 2 and water tank 4.Belt pulley 9 is installed on the output shaft of single cylinder diesel 3.Be provided with circulating water pump 6, radiator 10, cooling fan 11 in single cylinder diesel 3 outsides.The water intake of circulating water pump 6 is communicated with the cooling water channel 2 of single cylinder diesel 3 by intake pipe 5, and its water outlet is communicated with the water intake of radiator 10 by circulating pipe 8, and the water outlet of radiator 10 is communicated with the water tank 4 of single cylinder diesel 3 by return pipe 1.Cooling fan 11 is arranged on radiator 10 sides, and the center of its center and radiator 10 coincides, and the distance of 30mm～100mm is arranged.Circulating water pump 6 is connected with belt pulley 9 by belt 7.
In the present embodiment, cooling fan 11 can obtain power from single cylinder diesel 3 or other power plant.
During single cylinder diesel 3 work, circulating water pump 6 obtains power by belt pulley 9 and the belt 7 between the circulating water pump 6 that is connected on single cylinder diesel 3 output shafts from single cylinder diesel 3.Cooling liquid is by the flow through cooling water channel 2 of single cylinder diesel 3 of water tank 4, and heat absorption back temperature raises, and by being connected the intake pipe 5 between cooling water channel 2 and circulating water pump 6 water intakes, flow into circulating water pump 6; In circulating water pump 6, cooling liquid obtains supercharging, and the cooling liquid after the supercharging enters in the radiator 10 by circulating pipe 8 again; In radiator 10, cooling liquid is lowered the temperature to flowing through the heat radiation of radiator 10 ambient airs; At last, cooled cooling liquid flow back into by the return pipe 1 between the water tank 4 that is connected radiator 10 and single cylinder diesel 3 in the water tank 4 of single cylinder diesel 3, and so circulation endlessly.During cooling fan 11 work, air high speed flow mistake around the radiator 10 is to strengthen the cooling to cooling liquid.In single cylinder diesel 3 working procedure, liquid circulation flows, thereby reaches the operating temperature that reduces evaporative type single cylinder diesel 3, the purpose that improves its working efficiency.
