Condensing type fuel gas heat exchanger side plate

The utility model relates to a heat exchanger side plate, in particular to a condensing type fuel gas heat exchanger side plate, and belongs to the field of a heat exchanger. The condensing fuel gas heat exchanger side plate comprises a side plate body, wherein a first water inlet region is a low-temperature region, a water inlet is formed in the first water inlet region, the center axis line of the water inlet is vertical to the side plate body, an eleventh water outlet region is a high-temperature region, a water outlet is formed in the eleventh water outlet region, and the center axial line of the water outlet is vertical to the side plate body. The axial lines of the water inlet and the water outlet are vertical to the side plate body, and water pressure inside the heat exchanger is favorably reduced; the water outlet is directly communicated with the outer side surface of the side plate body without passing through a water outlet passage, the heat loss is reduced, and the heat conversion efficiency is higher; the unique water flow region is adopted, the water flow smoothness can be ensured, the water flowing speed is accelerated, the pressure difference is increased, the heat generated during the combustion is absorbed layer by layer, the maximum heat radiation area of the heat exchanger is ensured, and the heat conversion efficiency is improved.
