Problems solved by technology

[0004] Although the fins can improve the turbulence of the fluid, they also have the problems of large flow resistance and low pressure resistance, which makes it difficult for the plate-fin heat exchanger to be suitable for heat exchange between low-pressure fluid and high-pressure fluid.

Abstract

The invention discloses a heat exchanger. The heat exchanger comprises first sheet bars and second sheet bars, wherein a plurality of convex parts are arranged on the side of a first sheet face of each first sheet bar, fins are arranged between a second sheet face of each first sheet bar and a first sheet face of the second sheet bar adjacent to the first sheet bar, while no fins are arranged between the side, provided with the convex parts, of each first sheet bar and a second sheet face of the second sheet bar adjacent to the first sheet bar, and the height of the convex parts is smaller than that of the fins. According to the heat exchanger, the flow turbulent performance in a first fluid channel is improved through the fins, the flow turbulent performance in a second fluid channel is improved through the structure of the convex parts, thus low-pressure fluid can flow in the first fluid channel, and high-pressure fluid can flow in the second fluid channel.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchanger. Background technique [0002] Plate-fin heat exchangers are usually composed of plates and fins. Fins are placed between adjacent two plates to form a fluid channel; multiple such plates are stacked in different ways according to actual needs, and brazed into a whole to form a plate bundle; the plate bundle and the corresponding The plate-fin heat exchanger is formed by assembling the head, connecting pipe, support and other parts. [0003] Compared with the traditional heat exchanger, the plate-fin heat exchanger has a secondary surface and a very compact structure. The disturbance of the fins to the fluid makes the boundary layer of the fluid continuously rupture. At the same time, due to the high thermal conductivity of the plates and fins, The plate-fin heat exchanger has high efficiency. [0004] Although the fins can improve the turbulence of the ...
