Abstract

The model utility relates to a heat absorption slice for heat exchanger, comprising a basal plate up and down distributed with at least two lines of water pipe holes and tubular convex holes at the upper side of the lower water pipe holes, wherein fume channels are formed by vertically interpenetrating the tubular convex holes. The tubular convex holes are at the two sides of the upper water pipe holes. The tubular convex holes are approximately arranged in line and the fume channels in the tubular convex holes are continuously communicated with each other. The tubular convex holes are local rupture protrusion on the basal plate. Because the tubular convex holes on the basal plate form continuously communicated fume channels, the heat exchange condition of the heat absorption slice away from the heat is improved by guiding the flow of the hot air, finally the heat exchanger effectiveness of the whole gas water heater is increased to save the energy.
