Plate heat exchanger composite corrugated plate bind

Abstract

The invention discloses a plate exchanger compound ripple lamella bundle. A plurality of ripple plates are folded to form a lamella bundle of the plate exchanger; the ripple plate is struck out of a plurality of rectangle compound ripples arranged by matrix on a flat plate, and each matrix unit comprises two layers of ripples of different height and different shapes. Ripples arranged in the outer circle have relatively high wave height and a relatively big pitch of waves with the top being a bearing part between plates, and the ripples of the outer circle are arranged in pairs and in parallel with the vertical axes of two pairs of ripples forming a rectangle. Ripples heave transversely arranged in the rectangle, vertical ripples subside, and one or a plurality of raised inner layer ripples of relatively small wave height is / are arranged between the ripples of the outer circle. The invention has the advantages that the invention has high efficiency and intensifies the heat transmitting; the invention has a relatively wide flow passage and can allow relatively ropy liquid to get through; the invention enlarges the circulating surface, reduces the flowage resistance, and is helpful for energy saving and expense reducing in the industry process; the invention is easy to be processed, decreases the production cost and is helpful for the product popularization and application.

Description

technical field [0001] The invention relates to a heat exchanging element of a plate heat exchanger, which is especially suitable for a large-channel composite corrugated plate for heat transfer between two fluids. Background technique [0002] Plate heat exchanger is a compact and efficient heat exchanger widely used in petroleum, chemical, energy, HVAC, electric power and metallurgical industries. The research on the plate form is the core of the plate heat exchanger research. It is the pursuit of the majority of designers to develop plate types with high heat transfer efficiency, low flow resistance and wide adaptability. The existing plate types at home and abroad use simple corrugated plates, which are not ideal for heat transfer performance and rigidity, and the channel of the flow channel is narrow. Contents of the invention [0003] The purpose of the present invention is to provide a large-channel plate heat exchanger composite corrugated plate bundle suitable fo...
