Zusammenfassung:The invention discloses a combined type heat exchanger convenient to clean. The combined type heat exchanger comprises an outer shell, a heat exchange cavity, a flow guide cleaning mechanism, a heat exchange pipe, a second output valve, a first input valve, a first blow-down valve, a second cleaning valve and the like. The cleaning device is reasonable and simple in structure, low in production cost and convenient to mount, a movable plate moves rightwards through extension of an air cylinder, so that a sliding block can be integrally pushed into an opening in the left side of a heat exchange pipe through a connecting rod, and then cleaning liquid enters a conveying cavity through a first cleaning valve; and then the cleaning liquid pushes the whole sliding block to move rightwards along the interior of the heat exchange pipe, so that dirt on the inner wall of the heat exchange pipe can be cleaned out through the cleaning ring, and the cleaning liquid conveniently discharges the dirt through the first blow-do
