摘要： A fluid management device includes a control assembly (1), at least two block portions (2), and at least two valve core assemblies. The at least two block portions are hermetically connected to a same control assembly. The valve core assemblies are electrically connected to the control assembly. Each block portion includes a body portion. The body portion defines a mounting channel. A portion of the valve core assembly is located in an inner cavity of the control assembly, and another portion is located in the mounting channel. A gap is formed between two adjacent body portions for separating the body portions so as to reduce the possibility of heat transfer, thereby reducing harmful heat loss of the fluid management device.

摘要： A bidirectional filter and a heat pump system. The bidirectional filter comprises a housing (200) and at least two control value components (400). The two control value components (400) divide the inner chamber of the housing (200) into a filter chamber (211) and two transitional chambers (212, 213). The control value component (400) comprises a frame body (440) fixed on an inner wall of the housing (200), and an outlet blocking piece (430) fitting an outlet (441) of the frame body (440). The outlet blocking piece (430) is on an outer side of the frame body (440). The bidirectional filter further comprises a protective member (500) located in the filter chamber (211) and fixed relative to the housing (200). The protective member (500) is provided with a protective surface (501) opposite to an outer side surface of the outlet blocking piece (430). When the pressure of a refrigerant in the pipeline is too high, the protective surface (501) of the protective member (500) can limit movement of the outlet blocking piece (430), so as to prevent the flow cross-section between the filter chamber (211) and a connecting pipe (202) from being too small, and make the refrigerant pass smoothly, thereby reducing the adverse effect of the change of the pressure of the refrigerant on the bidirectional filter.

摘要： An electronic expansion valve comprises a valve seat (1), a nut (2) disposed on the valve seat (1), and a lead screw (4) in screw thread fit with the nut (2). With rotation of a magnetic rotor (5), the lead screw (4) drives a valve needle (3) to adjust a valve port flow of the electronic expansion valve. The nut (2) is provided with a nut guiding section (22). The lead screw (4) is provided with a lead screw guiding section (42) that fits the nut guiding section (22). An end portion of the nut (2) close to the nut guiding section (22) is provided with a noise reduction component (8), which is fastened by using a sleeve ring (9). The noise reduction component is disposed above the nut and is fastened by using the sleeve ring, so that the impact strength of the screw thread fit between the lead screw and the nut can be reduced, and the noise produced in operation can be reduced.
