A vertical shell and tube heat exchanger

The present invention relates to a vertical shell and tube heat exchanger, characterized in that: it comprises a vertical housing arranged in the housing, the lower ends are connected to a tank through a plate, the upper end of the housing is provided on the side shell-side inlet pipe, an outlet pipe provided at one side of the shell side of the lower end of the housing is provided with an inlet-side upper end of the tube at the top of the header tank is provided with a lower end of the tube located at the bottom of tank an outlet-side pipe, the spacer is provided with a plurality of staggered baffles notched inside the housing, two adjacent baffle side wall fastened to the different sides of the housing, a fluid communication between each of the baffle plates of channel, the free end of each baffle plate are lower than the connection end, through a heat exchange tube bundle arranged along each of the baffle, and both ends of the heat exchange tube bundle two plates fastened. Located within the housing with one side of each baffle are parallel to each other, the angle of each baffle and the horizontal plane is 15 ~ 25 °. The present invention prevents the formation of fluid in the baffle, to improve the heat transfer effect, increases the service life.
