second passages

1211, 1213 are fitted with the spool member or the connector, even if there is a member or a part located in another member, it is intended herein that the member or the part is located in the first or second passage as long as the member is located in the first or second passage of the core member.

The plate portion 121 has a plurality of plates stacked and fixed by welding, each adjacent plate has at least a first hole and a second hole, and the first holes of the plates are aligned and the second holes of the plates are aligned along the stacking direction of the plates. The first and second holes are located adjacent to the edges of the plate, so that the fluid flowing through the plate can have a longer flow path, which helps to improve the heat exchange efficiency. The first apertures of each plate are aligned to form a portion of the first aperture 1211 and the second apertures of each plate are aligned to form a portion of the second aperture 1213.

The top press piece 122 has a third hole 1221, the third hole 1221 being aligned with the first hole, and the bottom press piece 123 has a communication hole 1231, the communication hole 1231 being aligned with the first hole.

Of course, in other cases, the second communicating path 104 may not directly communicate with the second cell 1213, for example, a pipe may be provided in the second cell 1213 to communicate with the second communicating path 104 through the pipe. In other cases, the second communicating channel 104 may not be communicated with the interplate channels 1212 through the second cell channels 1213, the second communicating channel 104 may be provided on the side of the core member 12 where the first communicating channel 103 is provided, and the second communicating channel 104 may be adjacent to the first communicating channel 103 and not directly communicated with the first communicating channel 103.

The spool member 11 may be a spool portion of an electronic expansion valve. In this way, fluid from the connecting channel 138 of the connecting piece 13 can enter the interplate channels 1212 through the bottom opening 1115, the orifice 1114, the peripheral opening 1113 and the first bore 1211, so that the fluid can exchange heat with the fluid between the adjacent plates inside the plate portion 121. The peripheral openings 1113 may communicate directly with the first port 1211 or may communicate directly with the interplate passages 1212.

Herein, the fact that the connecting passage is not directly communicated with the first duct does not exclude the transition communication between the two through a flow passage provided by other components.

When the stacked plates are welded, because the outer diameter of the second section is smaller than or equal to the inner diameter of the welding matching part, the plates can move from the second section to the first section relative to the connecting piece, and welding allowance of the welding matching part is reserved, so that the welding sealing of the connecting piece and the core body part is facilitated, and the sealing matching of the valve core part and the connecting piece is also facilitated.
