Problems solved by technology

One is that there is a gap at the connection between the corrugated plate and the guide block, so leakage is easy to occur, which affects heat transfer; the other is that the heat transfer coefficient of the circular corrugated plate is not ideal, which affects the heat transfer effect

Abstract

The invention relates to a plate-shell heat exchanger with oval corrugated plates. The multiple oval corrugated plates form a corrugated plate bundle, each corrugated plate is provided with two corner holes correspondingly, the corrugated plate bundle is arranged in a shell, the shell is provided with a plate pass inlet and a plate pass outlet, and the plate pass inlet and the plate pass outlet are communicated through the corner holes in the corrugated plates; a guide block is formed between the corrugated plate bundle and the shell and divides the annular area between the corrugated plate bundle and the shell into a shell pass inlet cavity and a shell pass outlet cavity; the shell is provided with a shell pass inlet and a shell pass outlet correspondingly. The plate-shell heat exchanger is characterized in that the corrugated plates are oval, and the two corner holes of each corrugated plate are formed in the upper portion and the lower portion of the corrugated plate respectively.

Description

technical field [0001] The invention relates to an oval corrugated plate-shell heat exchanger. Background technique [0002] Plate heat exchangers are widely used in energy, power, heating, refrigeration and other fields due to their high heat transfer efficiency and compact structure. With the maturity of plate heat exchanger technology, it has replaced the traditional shell and tube heat exchanger in some fields. However, the existing rectangular plate heat exchanger generally has the problem of low pressure bearing capacity. In common high pressure fields such as petrochemical industry, the application of plate heat exchanger has been greatly restricted. Developing a plate heat exchanger that can withstand high pressure and has a compact structure has broad application prospects in the field of energy and power. Although there are some fully welded plate and shell heat exchangers at present, their working pressure generally does not exceed 4.5MPa, and their volume is r...
