Embodiment

[0052] figure 1 and 2 Show respectively the internal schematic diagram and the external schematic diagram of the water-cooled motor casing according to the exemplary embodiment of the present invention, image 3 A schematic diagram showing a sand core for manufacturing a water-cooled motor casing according to an exemplary embodiment of the present invention.

[0053] Such as Figure 1-3 As shown, the water-cooled motor casing according to the exemplary embodiment is provided with a water channel cavity 5 extending along a cylindrical surface. The water channel cavity 5 includes two C-shaped water channels 6 connected end to end in sequence. Wherein, the openings of the two C-shaped water channels face opposite directions. Such as figure 1 As shown, the two C-shaped water channels have openings 10 and 11 respectively, and the openings 10 and 11 face in opposite directions, so that the two C-shaped water channels are connected end to end to form a serpentine water channel ca...

Abstract

The invention discloses a water-cooling motor case, a sand core, and a method for manufacturing the water-cooling motor case. The interior of the water-cooling motor case is provided with a water channel cavity which extends along a cylindrical surface, and the water channel cavity comprises a plurality of C-shaped water channels which are connected in an end-to-end manner. According to the invention, the water channel cavity in the water-cooling motor case comprises the plurality of C-shaped water channels, and the C-shaped water channels are connected in the end-to-end manner. When cooling water flows in a water cooling channel, a turbulent flow can be generated at a corner, thereby facilitating the heat exchange, and improving the heat dissipation efficiency.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a water-cooled motor case for new energy vehicles, a sand core for manufacturing the water-cooled motor case and a method for manufacturing the water-cooled motor case. Background technique [0002] New energy vehicles generally require motors to be light in weight, small in size, and high in power density, so water cooling is generally used for motor cooling. At present, the production process methods of water-cooled motor casings for new energy vehicles mainly include the following: [0003] 1. The method of two-body welding of the inner shell and the outer shell. This process method needs to cast the inner shell and the outer shell separately, and then carry out mechanical processing respectively, process the spiral water channel on the inner shell, and then weld as a whole. The disadvantages of this process are waste of labor and time, low efficiency, high cost, and unsta...
