Problems solved by technology

Although the heat exchange effect of the plate heat exchanger using the herringbone plate is good, the corrugation of the traditional herringbone plate causes relatively large flow resistance, which makes the flow distribution uneven, which affects the further improvement of the overall performance of the plate heat exchanger and Further expansion of the scope of application

Embodiment Construction

[0013] combine image 3 , a plate heat exchanger plate with semi-cylindrical protrusions, including a plate main body, on which a positioning hole 1, a corner hole 2, a diversion area 3, a diversion area 4, and a heat exchange area 5 are arranged. The positioning holes 1 are located at both ends of the main body of the sheet for positioning. There are four corner holes 2 respectively located on the four corners of the plate main body, and the heat exchange medium flows through the corner holes 2 . The flow guide area 3 guides the heat exchange medium to the flow distribution area 4 . The split area 4 splits the heat exchange medium to different areas of the heat exchange area 5 . Corrugations 11 are arranged on the heat exchange area 5 along the flow direction of the heat exchange medium, and the corrugations are arranged symmetrically, that is, the identical plates rotate 180° and are completely pressed together.

[0014] The side of the herringbone corrugation 11 facing t...

Abstract

The invention provides a plate heat exchanger herringbone plate. The plate heat exchanger herringbone plate comprises a plate body; an angle hole, a guide area, a shunting area and a heat exchange area are arranged on the plate body; herringbone ripples are arranged in the flowing direction of a heat exchange medium in the heat exchange area; groove-shaped front small ripples are arranged on the surfaces, facing the flowing direction of the heat exchange medium, of the herringbone ripples; projected back small ripples are arranged on the other surfaces of the herringbone ripples; and the frontsmall ripples and the back small ripples are the same in shape.

Description

technical field [0001] The invention relates to a heat exchanger plate technology, in particular to a plate heat exchanger plate with semi-cylindrical protrusions. Background technique [0002] The world energy crisis in the 1970s strongly promoted the development of heat transfer enhancement technology. In order to save energy and reduce consumption and improve production economic benefits, it is required to develop high-efficiency heat exchange plates suitable for different requirements. In recent years, with the advancement of manufacturing technology and the development of enhanced heat transfer elements, the research on new high-efficiency heat exchangers has made great progress. According to different process conditions and heat transfer conditions, new types of heat exchangers with different structures have been designed and manufactured. Heat exchange plates have been applied and promoted in many industries, and have achieved great economic benefits. Therefore, in ...
