Claims

[Scope of utility model registration request]

Straight pipes housed in the can body to form an upper tube bundle and a lower tube bundle are arranged so that fluid flows into the tubes of the lower tube bundle and flows out from the tubes of the upper tube bundle, and so that these fluids do not mix. In a heat exchanger consisting of an inflow/outflow side lid provided with a partition plate at the top and a return side lid provided to reverse the flow of fluid in the lower stage tube bundle and transfer it to the upper stage tube bundle, the upper part inside the said return side lid and By narrowing the fluid passage going from the bottom of the tube to the top by providing a wall plate that projects a predetermined length from both ends of the side surface of the lower part approximately in the middle of the tube to the center of the tube and has a predetermined interval between the tip of each protrusion. A heat exchanger characterized by equalizing fluid distribution and improving efficiency.
