Summary of the invention
The invention provides that a kind of heat exchange area is large, heat transfer effect is better, and the liquid cooling casing of the electric motor coach drive motors that processing technology is simple, waste is less.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of liquid cooling casing of electric motor coach drive motors, this casing comprises the liquid cooling cavity between inner core, urceolus and inner core and urceolus, on urceolus, offer water inlet and delivery port, between inner core and urceolus, be provided with vertically multiple gussets, this gusset is divided into liquid cooling cavity the cyclic water channel of multiple intercommunications, is provided with the fin of ridge shape in described cyclic water channel.
Further, be provided with an Inlet and outlet water beam between described inner core and urceolus, described water inlet and delivery port are opened in respectively on the two ends of this Inlet and outlet water beam.
Described water inlet and delivery port bottom are equipped with tank, and wherein water inlet tank is contrary with delivery port tank opening direction and be communicated with respectively two adjacent cyclic water channels.
Described fin is fixedly installed on inner core vertically.
Further, the end, one group of diagonal angle of described adjacent two gussets offers watercourse port, and this watercourse port is communicated with adjacent two cyclic water channels.
Further, the open type cavity that the liquid cooling cavity forming between described inner core and urceolus is both ends open, liquid cooling cavity two ends are provided with outside seal assembly.
Described outside seal assembly comprises O grommet type seal and end cap seam, and this end cap seam is for being connected to liquid cooling cavity two ends by the interference of O grommet type seal.
Described outside seal assembly is bolted on gusset, and the both ends of described gusset all offer installation screw.
From above technical scheme, the present invention has following beneficial effect:
The present invention by arranging fin on the inner core of each cyclic water channel, increased the area of dissipation of inner core, in liquid cooling cavity, the heat exchange area of recirculated water increases, and radiating effect is more obvious, also the intensity of inner core is effectively strengthened, extend the useful life of liquid cooling casing simultaneously.The Inlet and outlet water beam arranging in liquid cooling cavity plays a part and strengthens beam action, makes liquid cooling casing more firm; Inlet and outlet water beam two ends arrange water inlet and delivery port, and are communicated with respectively two adjacent cyclic water channels by the contrary tank of opening direction, make recirculated cooling water abundant circulation heat absorption in liquid cooling cavity, improve the radiating effect of liquid cooling casing.Liquid cooling casing is designed to open type cavity, can adopt aluminium alloy once to draw moulding, enhances productivity, and reduces the waste of rapidoprint simultaneously, thereby lowers the production cost of liquid cooling casing.

Embodiment
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present invention is described in detail.
The invention provides a kind of for the drive motors of electric motor coach being carried out to cooling liquid cooling casing, as shown in figures 1 and 3, this liquid cooling casing is mainly made up of inner core 1 and urceolus 2, between inner core and urceolus, form the liquid cooling cavity 3 of an annular, in this liquid cooling cavity, be provided with vertically polylith gusset 6, gusset 6 is evenly divided into multiple cyclic water channels by liquid cooling cavity 3 along its circumferencial direction.The end, one group of diagonal angle of adjacent two gussets offers watercourse port, and this watercourse port is communicated with adjacent two cyclic water channels.
As shown in Figures 2 and 3, in one of them cyclic water channel, be provided with an Inlet and outlet water beam 8, the water inlet 4 of liquid cooling cavity 3 and delivery port 5 are opened in respectively on the two ends of this Inlet and outlet water beam, the bottom of water inlet 4 and delivery port 5 is equipped with tank, wherein water inlet tank 91 is contrary with delivery port tank 92 opening directions and be communicated with respectively two adjacent cyclic water channels, multiple cyclic water channels that are communicated with successively in whole like this liquid cooling cavity 3, are just formed, can make recirculated water flow in each water channel, absorb the heat in inner core 1, and carry out heat exchange with external refrigeration device, thereby arrive the effect of radiating and cooling.The middle part of Inlet and outlet water beam 8 also offers tight ingot screw 12, can use tight ingot screw to be fixed, and prevents that liquid cooling casing is loosening.
