Description

Cooling water jacket structure of motorcycle engine

Technical Field

The utility model relates to a motorcycle technical field especially relates to a motorcycle engine cooling water jacket structure.

Background

The water jacket has the function of transferring the temperature of the combustion chamber of the engine and the inner wall of the cylinder body to the cooling liquid through heat conduction, and the liquid can flow and circulate to the radiator through the water pump, and then the radiator radiates the heat of the cooling liquid through the flow of the outside air. When the existing motorcycle engine water jacket is used for cooling, dead angles of cooling liquid are easily generated, the local non-flowing of the cooling liquid is caused, the local temperature is overhigh, and the overall heat dissipation effect is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a cooling water jacket structure of a motorcycle engine.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the design is a motorcycle engine cooling water jacket structure, which comprises a first cylinder and a second cylinder, wherein a fixing ring is fixedly connected to the outer side of the upper end of the second cylinder and the first cylinder, a sleeve is fixedly connected to the outer side of the fixing ring, a cooling cavity is formed between the sleeve and the first cylinder and between the sleeve and the second cylinder, a water guide port is formed in the middle position of the lower end of the cooling cavity, two water guide ports are fixedly connected with connecting pipes, two ends of each connecting pipe are fixed through fastening mechanisms, a connecting block is fixedly connected to the outer side of the sleeve, a fixing frame is fixedly connected to the outer side of the connecting block, two sleeves are fixedly connected through connecting plates, one sleeve upper end is communicated with a water inlet pipe, and the other sleeve.

Preferably, the fastening mechanism comprises a fixing sleeve fixedly connected with the outer wall of the connecting pipe, the upper end of the fixing sleeve is fixedly connected with a fixing column, and the upper end of the fixing column is fixedly connected with the sleeve.

Preferably, a plurality of radiating fins are fixedly connected to two sides of the lower end of the sleeve at equal distances.

Preferably, the inner walls of the cooling cavity are coated with non-stick layers.

The utility model provides a pair of motorcycle engine cooling water jacket structure, beneficial effect lies in:

1. the cooling cavity, the connecting pipe and the water guide port are designed, so that the cooling liquid can flow conveniently, the situation that local non-circulation occurs to cause over-high local temperature is prevented, and the cooling effect is enhanced;

2. the design of receiving of fastening device plays fixed effect to the connecting pipe, prevents that the connecting pipe from appearing not hard up, and the design of on-stick layer prevents that water from being heated from generating the incrustation scale, causes the incrustation scale adhesion on cooling chamber inner wall, influences refrigerated effect.

Drawings

Fig. 1 is a schematic structural view of a cooling water jacket structure of a motorcycle engine according to the present invention;

fig. 2 is a top view of a cooling water jacket structure of a motorcycle engine according to the present invention.

In the figure: the water-cooling type water heater comprises a sleeve 1, a water inlet pipe 2, a first air cylinder 3, a fixing frame 4, a connecting pipe 5, a water guide opening 6, a second air cylinder 7, a connecting block 8, a water outlet pipe 9, a fixing ring 10, a connecting plate 11, a fixing sleeve 12, a fixing column 13, a cooling cavity 14 and cooling fins 15.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a motorcycle engine cooling water jacket structure, including first cylinder 3 and second cylinder 7, the equipartition distance fixedly connected with a plurality of fin 15 of sleeve 1 lower extreme both sides, the upper end outside fixedly connected with solid fixed ring 10 of second cylinder 7 and first cylinder 3, gu fixed ring 10 outside fixedly connected with sleeve 1, all form cooling chamber 14 between sleeve 1 and first cylinder 3 and the second cylinder 7, all coat the non-stick layer on the inner wall of cooling chamber 14, the non-stick layer is made for polytetrafluoroethylene, prevent the high temperature of water in cooling chamber 14, produce the incrustation scale, play the adhesion at the cooling chamber 14 inner wall, influence endothermic effect, fin 15's design, the radiating effect of sleeve 1 has been strengthened, be convenient for get rid of the absorbed heat.

The water guide port 6 has been seted up to 14 lower extreme middle part positions in cooling chamber, fixedly connected with connecting pipe 5 between two water guide ports 6, through injecting water in from inlet tube 2, water can be along 14 inner walls in cooling chamber downstream, under the effect of connecting pipe 5, water can go on along another 14 inner walls in cooling chamber upstream, discharge from outlet pipe 9 at last, cause the removal to the cooling water, prevent to cause the part of cooling water not to flow, cause local high temperature, the refrigerated effect has been strengthened, coolant liquid water for use, because the specific heat capacity of water is big, the while low price.
