Water treatment field and refrigeration and chemical industry technological process in, evaporate and condensation process as wherein important technical process, the heat transfer efficiency how improving this process receives the concern of more and more people.Along with the continuous expansion of maturation and the application gradually of plate type heat exchanger technology, in evaporation and condensation process, plate type heat exchanger just progressively replaces shell-and-tube heat exchanger, becomes the main heat transmission equipment of this technical process.As in field of seawater desalination, because of plate type heat exchanger compact conformation, the feature such as mounting or dismounting are convenient, heat exchange efficiency is high, structural material seawater corrosion resistance is strong, the evaporimeter in sea water desalinating unit and condenser all adopt plate type heat exchanger.But, Conventional plate-type heat exchanger plate all adopts shiny surface titanium plate or steel plate to process, for evaporation heat transfer or condensation heat transfer, its coefficient of heat transfer is relatively low, therefore the ability of enhanced boiling heat transfer and condensation heat transfer can significantly improve the heat exchange property of whole table apparatus.Seethed with excitement from strengthening and strengthening Condensation Theory, change sheet surface structure, significant to strengthening boiling and strengthening condensation.
Summary of the invention
For the problems referred to above, the invention provides a kind of for evaporating or the enhanced heat transfer component of condensation process, this enhanced heat transfer component is used for plate-type evaporator or plate-type condenser, the effect of strengthening boiling and strengthening condensation can be played, and can the features such as heat exchange area be increased, improve a lot than the heat transfer efficiency of general plate-type evaporator or plate-type condenser and Utilizing Rate.
To achieve these goals, technical scheme of the present invention is as follows:
For evaporating or the enhanced heat transfer component of condensation process, comprising plate body, it is characterized in that, at least one side surface of described plate body rolls out equally distributed projection or pit by rolling and forming technology.
In the present invention, the cross sectional shape of described projection or pit is the one in circle, rectangle, triangle, ellipse.
In the present invention, the equivalent diameter of described projection or pit is 0.1 ~ 0.5mm.
In the present invention, described pit depth or height of projection are 0.01 ~ 0.05mm.
In the present invention, described plate body has the side porosity of projection or pit to be 50% ~ 80%.
Material selected by plate body, according to the difference of working media, can select the materials such as titanium, titanium alloy, nickel, nickel-base alloy, stainless steel, copper alloy, carbon steel.
The present invention passes through at plate body surface rolling pit or protruding particle, to reach the object of enhanced water evaporation or condensation.According to concrete technological requirement and medium character, plate body can at one or both sides rolling pit or protruding particle.When the dirtier easy fouling of side medium or only have in whole heat transfer process side be evaporation or condensation heat transfer time, plate body one-sided rolling pit or protruding particle; When media of both sides all totally less scaling or side is evaporation heat transfer opposite side be condensation heat transfer time, plate both sides rolling pit or protruding particle.The present invention is applicable to the totally less scaling plate-type evaporator of medium or condenser, and the welded plate type heat exchanger that there is gas-liquid phase transition is as lamella heat exchanger.
The detailed description and obtaining that feature of the present invention can consult the graphic and following better embodiment of this case is well understood to.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below in conjunction with specific embodiment.
Embodiment 1
See Fig. 1, for evaporating or the enhanced heat transfer component of condensation process, comprise plate body 10, plate body is provided with corner apertures 11, heat transfer zone 12, seal groove 13, two road sealing groove 14, guiding region 16, wherein the corrugated form in main heat exchange district is the carinate ripple of fish.
See Fig. 2 and Fig. 3, be provided with protruding 15 on the surface of plate body.
Projection is triangular in shape is evenly distributed in plate side.Protruding cross sectional shape is circular (also can be other regular shapes such as rectangle, triangle, ellipse).Round diameter is 0.1 ~ 0.5mm; Described height of projection is 0.01 ~ 0.05mm; Plate has protruding side porosity to be 50% ~ 80%.
First by rolling and forming technology, equally distributed projection is rolled out to the plate material sheet adopted, then punch process is being carried out to plate, obtaining that there is corner apertures 11, guiding region 16, heat transfer zone 12, seal groove 13, two road sealing groove 14, the isostructural augmentation of heat transfer heat exchange plate of rat 15.
Embodiment 2
See Fig. 4, for evaporating or the enhanced heat transfer component of condensation process, comprising plate body 20, plate body 20 being provided with flanging 22, guiding region 23, heat transfer zone 21.The corrugated form of heat transfer zone is the carinate ripple of fish.
See Fig. 5, the surface of plate body 20 is provided with pit 24.
Pit is that square is evenly distributed in plate both sides, and the cross sectional shape of pit is also circular (also can be other regular shapes such as rectangle, triangle, ellipse).Round diameter is 0.1 ~ 0.5mm; Described pit height is 0.01 ~ 0.05mm; The porosity of plate pit is 50% ~ 80%.
According to concrete technological requirement and medium character, plate body can at one or both sides rolling pit or protruding particle, see Fig. 3, Fig. 5.When the dirtier easy fouling of side medium or only have in whole heat transfer process side be evaporation or condensation heat transfer time, plate body one-sided rolling pit or protruding particle; When media of both sides all totally less scaling or side is evaporation heat transfer opposite side be condensation heat transfer time, plate both sides rolling pit or protruding particle.The present invention is applicable to the totally less scaling plate-type evaporator of medium or condenser, and the welded plate type heat exchanger that there is gas-liquid phase transition is as lamella heat exchanger.
