The invention discloses an electronic expansion valve. The electronic expansion valve comprises a driving part, a valve element part, a containing cavity and a first installation cavity, wherein the valve element part is connected with the driving part, a motor assembly comprises a stator assembly, the stator assembly is arranged in the motor assembly in a sealed mode, the motor assembly is located in the containing cavity, part of the valve element part is located in the first installation cavity, and a first mounting cavity communicates with the containing cavity through a balance hole, so that when the electronic expansion valve works, a working medium can enter the containing cavity from the first mounting cavity through the balance hole, the working medium can be in contact with the periphery of the motor assembly, and under the action of the working medium, the heat dissipation of the motor assembly is facilitated, and the heat dissipation of the stator assembly is facilitated.
一种电子膨胀阀,包括驱动部件、阀芯部件、容置腔以及第一安装腔,阀芯部件与驱动部件连接,电机组件包括定子组件,定子组件内置于电机组件并密封设置,电机组件位于容置腔,部分阀芯部件位于第一安装腔,部分阀芯部件位于容置腔,第一安装腔和容置腔之间通过平衡孔连通,这样,电子膨胀阀在工作时,工作介质能够通过平衡孔从第一安装腔进入容置腔,工作介质能够与电机组件的外周接触,在工作介质的作用下,有利于提高电机组件的散热,进而有利于提高定子组件的散热。
