Zusammenfassung: | The utility model provides a flow guide device for an electronic expansion valve, the electronic expansion valve comprises a valve needle, a flow guide device annular wall and a flow guide wall, the annular wall is provided with a first end and a second end, a first fluid port is formed in the first end, and a second fluid port is formed in the wall of the annular wall; the flow guide wall is arranged at the second end, the flow guide wall is obliquely arranged relative to the axis of the annular wall, the flow guide wall and the annular wall jointly form a fluid channel, and a through hole is formed in the flow guide wall and used for containing the valve needle. By means of the structure, refrigerants can be effectively guided to pass through the flow channel of the electronic expansion valve, flow resistance is reduced, turbulent flow is restrained, and therefore noise can be reduced.
