摘要
电动割胶刀在持续作业过程中,内部的传动结构会产生热量,若不能及时将其传导至外界,会影响电动割胶刀的工作效果。针对该问题,从散热叶片的工作原理做出分析,对结构进行优化设计,采用SolidWorks软件的flow simulation流体分析插件,进行胶刀腔体内部的气流仿真模拟,然后从叶片的型式、数量和安装角度上提出了两种散热叶片的设计改进方案,最后对散热片改进前后的静压、涡量和气流轨迹进行比较。分析结果表明:改进后的两种型式散热叶片,静压值在出风口处更加稳定、涡量的数目明显增多、气流轨迹的分布也相对均匀,总体效果的提升相对改进前较为明显。
During the continuous operation of the electric rubber tapping knife,the internal transmission structure will generate heat.If it cannot be conducted to the outside in time,it will affect the working effect of the electric rubber tapping knife.Aiming at this problem,this paper analyzes the working principle of the cooling blades,optimizes the design of the structure,uses the flow simulation fluid analysis plug-in of SolidWorks software to simulate the airflow inside the glue knife cavity,and then the design improvement scheme of two kinds of heat dissipation blades is put forward from the angle of blade type,quantity and installation.Finally,the static pressure,vorticity and airflow trajectory before and after the improvement of the heat dissipation blade are compared.The results show that after the improvement of the two types of cooling blades,the static pressure value at the outlet is more stable,the number of vorticity is significantly increased,and the distribution of airflow trajectory is relatively uniform.The overall effect is improved more obviously than before the improvement.
