Problems solved by technology

Among them, the primary surface heat exchanger is usually processed from a thin metal plate with a thickness of 0.1-0.3mm. The metal plate is formed into fins with certain characteristics after stamping, and the multi-layer fins are stacked to form a heat exchange core. However, the existing The following difficulties exist in the design and manufacture process of the primary surface heat exchanger: 1. The fins inside the core are self-supporting and have high structural strength, but there is no support in the middle of the flange st

Abstract

The invention provides a primary surface type heat exchanger core. The primary surface type heat exchanger core comprises a plurality of heat exchanger fins arranged in parallel and sealing strips arranged on the edges of the heat exchanger fins, wherein the cross sectional area of the heat exchanger fins is equal to three times the product of the length of a periodic unit of the heat exchanger fins and the thickness of the fins. After the fins provided by the primary surface type heat exchanger core are subjected to edge pressing, the edge pressing thickness is approximately three times thatof the fins, the edge pressing strength is high, gaps in the pressed edges are tiny, and the welding performance of the fin pressed edges and the sealing strips is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of energy and power, in particular to a primary surface heat exchanger core. Background technique [0002] Heat exchangers are widely used in chemical, energy and other industries. At present, the commonly used forms of heat exchangers are shell and tube, plate-fin, plate and primary surface. Among them, the primary surface heat exchanger is usually processed from a thin metal plate with a thickness of 0.1-0.3mm. The metal plate is formed into fins with certain characteristics after stamping, and the multi-layer fins are stacked to form a heat exchange core. However, the existing The following difficulties exist in the design and manufacture process of the primary surface heat exchanger: 1. The fins inside the core are self-supporting and have high structural strength, but there is no support in the middle of the flange structure at the inlet and outlet, and the strength is low; The outlet structure often a...
