The notched base ring comprises a base ring sheet body including a top portion, a bottom portion, a first end connecting the top portion to the bottom portion, and a second end connecting the bottom portion to the top portion. The top portion includes a plurality of attachment lugs and defines a plurality of notches, each notch being at least partially defined by two lugs disposed on opposite sides of the notch, the top portion also including an angled top edge that is disposed at each of the attachment lugs, and the bottom portion includes a bottom support edge.

A shell and plate heat exchanger includes a shell forming an internal space, and a plate stack housed in the internal space. A plurality of refrigerant channels communicate with the internal space, and a plurality of heating medium channels are blocked from the internal space. Each of the refrigerant channels is adjacent to an associated one of the heating medium channels with heat transfer plate interposed between. Each of the heat transfer plates includes a first communication hole that communicates with the heating medium channels to introduce the heating medium, a second communication hole formed below the first communication hole that communicates with the heating medium channels to emit the heating medium, and a guide crossing between the first and second communication holes to guide the heating medium that has flowed into the heating medium channels from the first communication hole toward side portions of the heat transfer plate.

A heat exchanger includes tubes, a tank, and a prevention plate arranged inside the tank and contacting end surfaces of the tubes to prevent heat medium from flowing into the tubes in a certain region. Flow paths are formed in each tube and arranged in a width direction of the tube. The prevention plate includes a deformable portion elastically deformable by contacting an edge of the opening at a time of inserting the prevention plate into the tank from the opening. The deformable portion of the prevention plate that has been inserted into the tank is restored and receives a reaction force from an inner surface of the tank such that the prevention plate is shifted along the width direction by the reaction force.
