PURPOSE: A cross flow type heat exchanger is provided to recover exhaust energy contained in hot-water drain, steam drain, overflow water, and cooling water discharged after being used in building equipment and production facilities and reuse the exhaust energy as water preheating and precooling resources. CONSTITUTION: A cross flow type heat exchanger is composed of a double jacket-type cross flow heat exchanging unit(10) including a pair of fixing pipe plates mounted at regular intervals with having a plurality of heat transferring tube fitting grooves, outer heat transferring tube plates(13) mounted at the upper and lower parts, and the front and rear between the fixing pipe plates, and an inlet(14) and an outlet installed at the upper and lower of the outer heat transferring tube plate to flow in and out fluid; a plurality of heat transferring tubes(20) of which sides are inserted and fixed to the heat transferring fitting grooves to alternatively open; a plurality of first inductive division plates(30) of which sides are fixed to the rear outer heat transferring tube plate, dividing between the heat transferring tubes and having a water passage at the front; a cross flow inductive member blocking up the extended part of the heat transferring tube and guiding fluid flowing along the outside to flow at a right angle by the first inductive division plate; a heat absorbing channel part(50) integrated to both sides of the heat exchanging unit to form a space(51) passed through by heat absorbing resources and formed with an inlet(52) and an outlet(53) at the upper and lower; and a second inductive division plate(60) fixed to an outer plate(54) of the heat absorbing channel part, penetrating and dividing the heat transferring tube into upper and lower parts, having a water passage(61) at the front, accordingly deciding the flow direction and velocity of fluid, and obtaining excellent heat transferring efficiency.
