Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
In the embodiment, the engine cover structure comprises a shell 110, wherein the shell 110 is in a basin-shaped structure, a hollow part 111 is arranged at the bottom of the shell 110, a connecting surface 120 is arranged at the top of the shell 110, and a cavity of an archimedean spiral structure is formed on the side wall of the shell 110.
In this embodiment, as shown in fig. 1 to 4, the engine cover is formed by stamping or casting, and includes a casing 110, wherein the casing 110 is integrally formed into a basin-shaped structure, a through hole is integrally formed at the bottom of the casing 110 to form a hollow portion 111, and the area of the hollow portion 111 matches with the area covered by the fan blades of the engine cooling fan, so as to facilitate air suction of the engine fan, and prevent other impurities from entering the casing 110. The top of the shell 110 is provided with a connecting surface 120, which is convenient for the shell 110 to be connected with a cylinder body or a cylinder cover and is convenient for the assembly of the shell 110; a cavity having an archimedes spiral structure is formed inside the sidewall of the case 110, and the cavity is also formed along the inside of the sidewall of the case 110 with the rotation center of the heat dissipation fan as the center; after the structure is assembled with the cylinder body, the cavity forms a heat dissipation air duct which adopts an Archimedes spiral structure, so that the obstruction of the shell 110 to cooling air is reduced, the heat dissipation efficiency of the cooling air formed by the heat dissipation fan is improved, and the service efficiency of the engine heat dissipation fan is improved. Through tests, compared with the prior art, the structure of the cooling fan improves the heat dissipation efficiency of the cooling fan by more than 30%; on the engine with the same power, a heat radiation fan with smaller power compared with the prior art can be arranged, so that the running cost and the manufacturing cost of the engine are reduced; in addition, the appearance of the cooling fan with low power is relatively small, so that the overall appearance size of the engine is indirectly reduced, and the transportation and the installation of the engine are facilitated.
Further, in the present embodiment, as shown in fig. 1-2; the bottom of the shell 110 is provided with a first connecting part 112; the first connecting part 112 is arranged around the hollow part 111 of the shell 110, wherein the first connecting part 112 corresponds to the side wall of the cylinder body, and the structure of the present application can be effectively fixed on the side wall of the cylinder body through the arranged first connecting part 112, so that the assembly is convenient; for further convenience in assembly, the first connecting portion 112 in the present application adopts a structure with a plurality of groups of bolt holes, and when in specific use, the bolt holes are penetrated through by a bolt assembly, so that the structure of the present application is fixed on the side wall of the cylinder body; in another embodiment of the present application, in order to reduce the weight of the housing 110, a hollow structure 113 is further disposed at the bottom of the housing 110; in this application, can set up hollow out construction 113 around well kenozooecium 111, so when reducing weight, can also improve radiator fan's the area that induced drafts, further increase radiator fan's radiating efficiency.
