The utility model belongs to the
waste heat recovery technical field, concretely relates to a
waste heat recovery equipment, including heat
recovery channel, the evaporimeter of setting in the air outlet of heat recovery channel and the water tank of setting in the inboard of evaporimeter, the included angle of the side wall surface opposite water tank and evaporimeter is
acute angle, the horizontal cross section of water tank is trapeziform, the utility model discloses the included angle of the side wall surface opposite water tank and evaporimeter is
acute angle, so that the side of water tank and evaporimeter have certain angle of inclusion, and the hot air plays a guiding effect, and increases heat recovery efficiency, trapeziform water tank design, cleverly utilize the trapeziform gap of one end of evaporimeter contacted, and the sufficient clearance is left, and forms a half horn mouth smooth air duct, and the air inlet guiding effect is enhanced.
