Abstract

The invention discloses a fluid guide plate and a plate heat exchanger thereof. The fluid guide plate comprises a first heat exchange surface, a second heat exchange surface and a plurality of heat exchange parts, wherein the first heat exchange surface is sunken facing the second heat exchange surface to form the heat exchange parts, and the heat exchange parts are arranged on the second heat exchange surface in a protruding manner; and each heat exchange part has a polygon shape. The plate heat exchanger comprises a plurality of the fluid guide plates, and the heat exchange parts on the adjacent fluid guide plates are mutually staggered to form a runner system, so that the heat exchange parts can allow fluids to vigorously flow in the runner system to form a longitudinal eddy current, strong turbulence is generated, the heat transfer efficiency of fluids is improved, and the pressure drop is reduced; and besides, through the adoption of the fluid guide plate, the mold development can be greatly reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a plate heat exchanger, in particular to a plate heat exchanger with a fluid guide plate of a polygonal heat exchange part. Background technique [0002] At present, the plate heat exchangers are all made of stamped concave-convex stainless steel plates arranged side by side, and the concave-convex pattern is the most common. The mountain-shaped concavo-convex lines of two adjacent plates form a 180° opposite combination, so the concavo-convex ridges of the two adjacent plates form staggered contact points, thereby forming the staggered channel system of the plate heat exchanger. This staggered channel system is designed to make the fluid flowing into the plate heat exchanger generate strong turbulence to achieve high heat transfer effect. For example, the way of fluid flow in a plate heat exchanger is that one side of the channel passes through the cold fluid, the next side of the flow through the hot fluid, and the next side...
