Abstract
The invention discloses a motor air-cooled casing based on integrated extrusion molding and phase-change heat pipe technology. The casing comprises a pipe shaped casing; the side wall of the casing is provided with at least four installation holes; the installation holes are provided with phase-change heat pipes and the outer side wall of the casing is provided with heat radiating fins. According to the invention, the casing utilizes phase-change heat pipes as heat conduction and soaking components; the phase-change heat pipes possess extremely high efficient heat conduction capability and the heat conduction coefficient is ten thousand times as that of the known metal and could achieve the rapid re-organization of the distributed heat energy inside a drive motor. As the phase-change heat pipes are installed in the installation holes, the large amount of heat concentrated in the stator core and the casing contact part can be spread rapidly to the entire casing, therefore, eliminating the problem with the over-heat in some parts of the casing and reducing the temperature difference of the casing substantially. In this way, the heat distribution can be re-organized so that more heat can be transmitted from the stator windings and the stator core to the fins on the casing for heat radiation and more excellent temperature control performance can be achieved for the drive motor.
