A motor cylinder with water cooling and air cooling functions

Abstract

The invention discloses a motor cylinder block with water cooling and air cooling functions, the cylinder block includes a block body having an inner cavity for accommodating a rotor, the outer wall of the block body is provided with cooling fins, between the inner cavity and the outer wall of the block body, a plurality of pipe cavities through which cooling water flows are arranged, the longitudinal direction of the pipe cavity is parallel to the self-axis of the block body, and partition ribs are arranged in the pipe cavities along the axial direction of the block body, wherein each pipe cavity is divided into two single pipes by the partition rib, and an axial concave notch is arranged at the same end of the partition rib, and the notch connects two single pipes in the same pipe cavity. An end cap is included and is fitted to the end of the block body. The end cap comprises a flat end cap and an inlet and outlet end cap respectively arranged with both ends of the block body, the flat end cap is arranged with one end close to the notch, and the inlet and outlet end cap is provided with a connecting passage inside, and the connecting passage communicates with each single pipe inthe adjacent pipe cavity. The water cooling and air cooling forms of the invention are combined with each other, and the cooling efficiency is high. The distance of the waterway is increased, coolingwater circulation is realized, and further the heat transfer efficiency is improved.

Description

technical field [0001] The invention relates to the field of motor cylinders, in particular to a motor cylinder with water cooling and air cooling functions. Background technique [0002] The motor will inevitably generate a large amount of internal energy during long-term operation, resulting in an increase in the temperature of the motor itself. It is necessary to dissipate heat and cool down the motor. The traditional heat dissipation method is to install a heat sink on the motor casing for air cooling, but Air cooling has limited efficiency and cannot adapt to higher heat dissipation requirements. Contents of the invention [0003] The problem to be solved by the present invention is to provide a motor cylinder with water cooling and air cooling functions, the water cooling and air cooling forms are combined with each other, and the cooling efficiency is high. Increase the distance of the waterway, realize the circulation of a cooling waterway, and further improve the...
