Plate heat exchanger
By providing a first arc-shaped spoiler in the plate heat exchanger, the possibility of fluid flowing through the edge area of the plate sheet is increased, and the problem of low heat exchange efficiency caused by fluid flowing through the intermediate area in the plate heat exchanger is solved, thereby achieving a more efficient heat exchange effect.

AI Technical Summary
Technical Problem
In a plate heat exchanger, fluid flows in the middle area of the plate, resulting in a short heat exchange path and affecting the overall heat exchange efficiency.
Method used
A plate heat exchanger is designed, and a first plate and a second plate are arranged in a stacked layer, and a first arc-shaped spoiler is provided in the fluid distributor, which is located on the side of the inlet angle hole facing the outflow angle hole, thereby increasing the flow resistance and allowing the fluid to be distributed more evenly through the edge area of the plate.
Benefits of technology
By increasing the flow rate of fluid flow through the edge area of the plate and extending the flow path, the overall heat exchange efficiency of the plate heat exchanger is improved.

Abstract
The plate heat exchanger at least comprises a first plate piece and a second plate piece which are arranged in a stacked mode, the plate heat exchanger is provided with a first heat exchange channel, the first heat exchange channel is located between the first plate piece and the second plate piece, the first plate piece is provided with an inflow angle hole and an outflow angle hole, and the first heat exchange channel communicates with the inflow angle hole and the outflow angle hole; the plate heat exchanger comprises a fluid distribution piece, the fluid distribution piece is fixed to the first plate sheet, the fluid distribution piece at least comprises a first arc-shaped turbulent flow part, and the first arc-shaped turbulent flow part is located on the side, facing the outflow angle hole, of the inflow angle hole. According to the plate heat exchanger, the flow resistance of the side, facing the flow outlet corner hole, of the flow inlet corner hole is increased, so that the flow of fluid flowing from the flow inlet corner hole to the flow outlet corner hole can be reduced, the flow of fluid with a short heat exchange path can be reduced, more fluid tends to flow through an area with a long heat exchange path, and the heat exchange efficiency is improved. And the overall heat exchange efficiency of the plate heat exchanger can be improved.
