Kind Code:
A1
Abstract:
Disclosed are an electronic expansion valve (1) and a thermal management assembly (400). The electronic expansion valve comprises a valve core (13), a rotor assembly (14), a stator assembly (15) and a circuit board (16), wherein the rotor assembly is electrically connected to the circuit board. The electronic expansion valve has a valve port (120), and the valve core moves with respect to the valve port; a valve body (11) comprises a first flow portion (23), a second flow portion (24), a first cavity (210) and a second cavity (220), wherein the first cavity is located above the valve port and the second cavity is located below the valve port; the first flow portion comprises a first connection section (232) and a first subsection (231), the first connection section is used for connecting to an external connection pipe (10), and the first subsection is directly in communication with the first cavity; the second flow portion comprises a second connection section (243) and a second subsection (241), the second connection section is used for connecting to an external connection pipe (5011), and the second subsection is directly in communication with the second cavity; in a clockwise direction, an angle formed between at least one of the center line of the first subsection and the center line of the second subsection and the center line of the valve core is an acute angle; and in this way, the electronic expansion valve can be mounted to a connection pipe of an adapter (501) and a connection pipe of an external system in a matching manner.
