Embodiment Construction

[0015] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0016] As shown in Figure 1, 2 or 3, the technical solution for the specific implementation of the present invention is: a heat exchange plate for a plate evaporator, based on the heat exchange plate base 1, the upper end surface of the heat exchange plate base 1 is processed The micro-ribs 2 are provided with dimples 3 or a rough structure is processed on the upper end surface of the heat exchange plate substrate.

[0017] The micro-ribs 2 processed on the upper end surface of the heat exchange plate base 1 are uniformly distributed, the height of the micro-ribs 2 is 0.02-0.05 mm, the length is 0.1-0.5 mm, and the width is 0.1-0.5 mm The distance bet...

Abstract

The invention belongs to the technical field of heat transmission, and relates to a heat exchange plate, in particular to a heat exchange plate for a plate-type evaporator. On the basis of a heat exchange plate substrate, the upper end face of the heat exchange plate substrate is provided with micro ribs and micro grooves, and alternatively, the surface of the heat exchange plate substrate is provided with rough structures. The heat exchange plate has the advantages that multiple rough surfaces can increase vaporization core number, reduce the degree of superheat of the wall surface, strengthen boiling heat transfer, and further improve the total heat transfer coefficient of the evaporator.

Description

technical field [0001] The invention belongs to the technical field of heat transfer, and relates to a heat exchange plate, in particular to a heat exchange plate for a plate evaporator. Background technique [0002] In the existing technology, the plate heat exchanger has the advantages of high heat transfer efficiency and compact structure, and has been widely used in the production processes of chemical industry, refrigeration, food and medicine. In recent years, with the in-depth research on complex working conditions, plate heat exchangers have also been expanded from simple single-phase working conditions to complex working conditions with evaporation or condensation. The design pressure of the traditional detachable plate heat exchanger is usually less than 2.5MPa, and the design temperature is less than 350°C, which is suitable for low temperature and low pressure occasions. In order to overcome the limitation of temperature and pressure, detachable fully welded pla...
