Abstract

The utility model relates to a novel baffle plate which comprises a baffle plate body, a round hole, a flow guide structure and an anti-corrosion layer. The baffle plate body is a segment-type baffle and is made of stainless steel, the surface of the baffle plate body is uniformly provided with round channels, and the area of holes accounts for 60-90% of the total area. The round hole is a through hole with a hole diameter of 8-20 mm. The flow guide structure is of an arc-shaped structure and is welded to a round end face of the baffle plate body, so that a right-angle transition area is prevented from being formed on the welding position of the baffle plate body and a condenser, and a flow dead area formed on the position is eliminated. The anti-corrosion layer is located on the outer end face of the baffle plate body, and the situation that acid or alkaline matter in water can easily corrode the baffle plate body in the condenser is avoided. According to the baffle plate body arranged in the condenser, when fluids in the condenser pass through the baffle plate body and flow through the round hole, due to the fact that the hole diameter becomes smaller, the flowing speed of liquid is increased, flowing liquid in the condenser passes through the flow guide structure of the baffle plate and flows at a certain arc in a transition mode, and accordingly the flow dead area is avoided, and the novel baffle plate is simple in structure and convenient to manufacture.
