Description

Water cooling mechanism for motorcycle engine
Technical Field
The utility model relates to a motorcycle engine, especially a motorcycle engine water-cooling mechanism.
Background
At present, most engines mostly adopt a water-cooling mode, namely, a water pump is adopted to introduce cooling liquid into a heat engine water channel, and the cooling liquid in the heat engine water channel exchanges heat with the engines, so that the heat load of the whole engine is reduced, and the reliability of the engines is improved. However, most of the existing connection methods of the water pump and the cylinder body are that the water pump is connected with an external water pipe, namely the water pump is assembled on the engine, and then the water pump is connected with a cooling liquid channel in the cylinder body through the external water pipe, namely the cooling liquid flows into the water pump → the external water pipe → the cylinder body → the cylinder head → the thermostat, so that heat exchange is carried out on the engine through circulation, the heat load of the whole engine is reduced, and the reliability of the engine is improved.
The "external water pipe" in traditional water course arrangement has following not enough:
1. the cost is increased, an external water pipe and a clamp are required to be designed independently, and the cost of the engine is increased;
2. the assembly is complicated, the external water pipe needs to be assembled independently, the number of parts is large, and the reliability is poor;
3. the risk of water leakage is high, and the external water pipe has the risk of water leakage in the running process of the engine, and the safety performance is poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a convenient assembling can effectively prevent motorcycle engine water-cooling mechanism who leaks.
The utility model aims at realizing through such technical scheme, a motorcycle engine water cooling body, including cylinder head and cylinder body be provided with cylinder head cooling water course die cavity and cylinder body cooling water course die cavity in the cylinder head and the cylinder body respectively, cylinder head cooling water course die cavity and cylinder body cooling water course die cavity intercommunication the outside of cylinder head is provided with the water pump with cylinder head cooling water course die cavity intercommunication just keep away from on the cylinder head the water pump be provided with the outlet pipe of cylinder head cooling water course die cavity intercommunication.
The cylinder head cooling water channel cavity comprises a water inlet and a water outlet, and the water pump is arranged at the water inlet and communicated with the water inlet; the water outlet pipe is communicated with the water outlet.
Further, the cylinder head cooling water channel cavity comprises a cavity A and a cavity B which are arranged in the cylinder head and are independent, and the cavity A and the cavity B are both communicated with the cylinder body cooling water channel cavity; the water pump is communicated with the cavity A, and the water outlet pipe is communicated with the cavity B.
Since the technical scheme is used, the utility model has the advantages of simple structure, convenient assembling, use reliably, low cost, adopt it to carry out the heat exchange to the engine, reduce whole quick-witted heat load, improve the engine reliability, simultaneously, reduced the assembly of external water pipe, the cost is reduced, and effectively prevented the risk of leaking and taken place.
Drawings
The drawings of the utility model are as follows:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a cross-sectional view of fig. 1.
Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or substitutions in the basic spirit of the embodiments will still fall within the scope of the present invention as claimed in the appended claims.
Example 1: as shown in fig. 1, a water cooling mechanism for a motorcycle engine comprises a cylinder head 1 and a cylinder block 2, wherein a cylinder head cooling water channel cavity and a cylinder block cooling water channel cavity 3 are respectively arranged in the cylinder head 1 and the cylinder block 2, the cylinder head cooling water channel cavity is communicated with the cylinder block cooling water channel cavity 3, a water pump 4 communicated with the cylinder head cooling water channel cavity is arranged on the outer side of the cylinder head 1, and a water outlet pipe 5 communicated with the cylinder head cooling water channel cavity is arranged on the cylinder head 1 and far away from the water pump 4.
The cylinder head cooling water channel cavity comprises a water inlet 6 and a water outlet 7, and the water pump 4 is arranged at the water inlet 6 and communicated with the water inlet 6; the water outlet pipe 5 is communicated with the water outlet 7.
Further describing, in the novel usage model, the cylinder head cooling water channel cavity comprises a cavity A8 and a cavity B9 which are arranged in the cylinder head 1 and exist independently, and the cavity A8 and the cavity B9 are both communicated with the cylinder block cooling water channel cavity 3; the water pump 4 is communicated with the cavity A8, and the water outlet pipe 5 is communicated with the cavity B9.
In the utility model, the cooling liquid flows into the cavity A8 from the water pump 4, then flows into the engine water tank from the water outlet pipe 5 after passing through the cylinder block cooling water channel cavity 3 and the cavity B9, and the cooling liquid flows into the water pump 4 after being radiated by the water tank, so that the heat exchange is carried out on the engine by the circulation, the heat load of the whole engine is reduced, and the reliability of the engine is improved; because the whole water channel adopts the built-in water channel structure, the process structure is simple, the assembly is convenient, and the use is reliable.
