Embodiment
Referring to figs. 1 through Fig. 6, a kind of motor casing with heat sinking function, comprise housing 1 and the forward and backward end cap 2,3 being fixed on the forward and backward end of housing 1, described housing 1 is the annular solid of hollow, be positioned at housing 1 and be provided with multiple through hole 11 running through its front and back ends, described front end housing 2 is provided with multiple forward recess 21, and described rear end cap 3 is provided with multiple rearward recess 31; Wherein, each forward recess 21 and adjacent two through hole 11 front end are connected, each rearward recess 31 is connected with adjacent two through hole 11 rear end thus forms the circulation flow-guiding channel of a S shape, motor casing is provided with the entrance 4 that is connected with flow-guiding channel and exports 5.
Wherein, entrance 4, outlet 5 can be arranged on housing 1 or forward and backward end cap 2,3, as long as water or the fluid such as oil or gas can be realized can to circulate along flow-guiding channel under the effect of compression pump.
Use compression pump will be connected to entrance 4 and outlet 5 ends of motor casing into and out of pipeline respectively, water or the heat eliminating medium such as wet goods liquid or cold air are sent in circulation flow-guiding channel from entrance 4, and are back to compression pump from outlet 5 thus reach the object to motor cycle heat radiation; This motor casing, owing to have employed said structure, directly arranges S shape circulation flow-guiding channel compared to existing on housing, and what this motor casing adopted is that forward and backward end cap 2,3 opens multiple groove respectively, is combined into circulation flow-guiding channel with clear opening 11 multiple on housing 1.Like this when realizing S shape circulation flow-guiding channel structure, only need to housing 1, these three parts perforates respectively of forward and backward end cap 2,3, slot, greatly simplify processing technology, improve production efficiency.And if employing water or wet goods liquid dispel the heat through circulation flow reversal groove, after motor casing uses a period of time, incrustation scale or grease is had unavoidably in circulation flow-guiding channel, at this moment only housing 1 and forward and backward end cap 2,3 need be split, directly to these directly to hole, groove carry out clean, clean very convenient, cleaning effect is very good.
