Embodiment Construction

[0033] The technical solution of the present invention will be further introduced below in conjunction with the accompanying drawings.

[0034] combine figure 1 and figure 2 As shown, the surface porous high flux heat transfer plate tube 1 of the present invention includes a plate tube base 11 and a porous metal layer 12 . The plate tube base 11 is formed by pairing upper and lower heat transfer corrugated plates. Adjacent surface-porous high-flux heat transfer plate tubes 1 are arranged in parallel at a certain distance, and the enclosed space is used as a low-temperature medium side channel. Adjacent sheets of the porous high-flux heat transfer plate tube 1 on the same surface form through holes 13 as high-temperature medium flow channels.

[0035] Preferably, the heat transfer corrugated plate is made by molding process, and the wall surface of the heat transfer corrugated plate is sinusoidally corrugated along the flow direction. The thickness of the heat transfer cor...

Abstract

The invention relates to a high-flux heat transfer plate and tube with a porous surface and a plate reboiler. The high-flux heat transfer plate and tube with the porous surface is disclosed in order to solve the problems that an existing heat transfer plate is low in rigidity and poor in deformation resistance, and warping deformation and a high rejection rate exist during high-temperature sintering. The high-flux heat transfer plate and tube with the porous surface comprises a plate and tube substrate and a porous metal layer, the outer surface in the length direction of the surface of the plate and tube is of a corrugated structure, wave peaks on the upper surface correspond to wave valleys on the lower surface, and a plurality of parallel and independent penetrating holes are formed; and the porous metal layer is located on the outer surface of the plate and tube substrate. According to the high-flux heat transfer plate and tube with the porous surface, liquid evaporation can be accelerated, the boiling heat transfer efficiency is improved, the deformation resistance is high, and the yield of the high-flux heat transfer plate and tube with the porous surface is increased.

Description

technical field [0001] The invention relates to an evaporator, a vaporizer and a reboiler used in the field of energy and power engineering, in particular to a surface porous high-flux heat transfer plate tube and a plate reboiler. Background technique [0002] The plate heat exchanger has the characteristics of high compactness and high heat transfer coefficient, and can be used for medium boiling, evaporation heat transfer and material separation. [0003] Plate boiling heat transfer equipment is widely used in oil refining, chemical industry, refrigeration, nuclear energy, food processing, industrial waste liquid concentration, air separation, and seawater desalination. For example, plate-type rising film and falling film steamers used in food, light industry, and refrigeration industries. The heat transfer element of the existing plate-type boiling heat transfer equipment is generally a metal corrugated plate with a smooth surface. [0004] The heat transfer theory sho...
