Bionic honeycomb-type plate sheet for plate-type heat exchanger

Abstract

The invention discloses a bionic honeycomb-type plate sheet for a plate-type heat exchanger, comprising a flow guiding region, a sealing region, a honeycomb region and a frame, wherein the honeycomb region is composed of a plurality of peripheral regular hexagons which are sequentially connected with each other in longitudinal and transverse directions, so as to form a honeycomb shape; a plurality of peripheral regular hexagons are uniformly and densely distributed on the bionic honeycomb-type plate sheet; a central regular hexagon is arranged at the center of each peripheral regular hexagon and the central regular hexagon is in a protruding structure; a connecting part between two peripheral regular hexagons is in a protruding structure and a ripple-like structure is formed by connection of connecting parts among the plurality of the peripheral regular hexagons; and a flow channel is formed by the peripheral regular hexagons between each protruding central regular hexagon and the ripple-like structure. According to the invention, the fluid is interfered by the flow channel and concave-convex structures of the central regular hexagons and the ripple-like structure in the process of flowing in a hollow cavity, and the heat-exchanging efficiency is improved; and the dense honeycombs such a plurality of I beams, which are mutually limited, can dispersedly bear pressure from a panel, so as to increase the use condition and range of the plate sheet.

Description

technical field [0001] The invention relates to a heat exchange plate, in particular to a bionic honeycomb plate for a plate heat exchanger. Background technique [0002] Plate heat exchangers and plate heat exchange devices are indispensable equipment in the process of industrial heat transfer and heat energy utilization, including power, chemical, metallurgy, food, light industry and other industrial sectors, and are also important components of air conditioning and heating equipment. The traditional plate heat exchanger is a heat exchange device made of heat transfer plates with a certain corrugated shape, which are compressed by rubber gaskets according to the required intervals. When the heat exchange plates are assembled in the plate heat exchanger, the heat exchange plates of each interval channel are arranged alternately, and the rubber sealing strips are fixed with adhesive between the plates, and the function is to prevent fluid leakage and make the two Fluid heat...
