Description
Technical field
The present invention relates to the manufacturing methods of a kind of raw sheet material as heat exchange plate and the raw sheet material.
Background technology
The heat exchange for being assembled in heat exchanger etc. requires high thermal conductivity with plate.Want to improve conductivity of heat, in plate surface shape
Carry out enlarged surface product at micron-sized fine bumps to be preferred.Quote micron-sized fine concave-convex side as in plate surface
Method develops technology shown in such as patent document 1 and patent document 2.
Patent document 1 it is disclosed to the method for quoting of metal sheet surface be that will quote to the concavo-convex of the peripheral surface for quoting roller
The portion of quoting press on by the rotation of transfer roller transfer come metal sheet method.In the method, in metal sheet
Surface formed with the concaveconvex shape that quote portion roughly the same of quoting roller by the portion of quoting.
In addition, the raw sheet material of heat exchange plate disclosed in patent document 2 is by being formed with fine concave-convex titanium on surface
Flat-sheet material is formed, and becomes heat exchange plate after implementing punch process to the flat-sheet material as post-processing.In the raw sheet material, the original
The bumps on the surface of plank are set to：Make by protrusion height (μm) × [between the protrusion of the width (μm) of recess portion × adjacent
Angle (deg) away from (μm)/protrusion] form parameter that defines becomes 0.94 or less.
Technology disclosed in patent document 1 forms micron-sized fine bumps in heat exchange plate, on the surface of flat-sheet material
Carry out enlarged surface product, to improve conductivity of heat.But in most cases, fine concave-convex raw sheet material is formed on surface
The case where (flat-sheet material) becomes heat exchange plate with original shape (that is, in the case of remaining concave-convex) is few.
In general, forming the protrusion (example that multiple height are several mm to several cm on the surface of heat exchange plate by punch process
Such as the protrusion for the chevron shape for being known as " herringbone ").Therefore, in the technology disclosed in patent document 1, it is formed in the table of raw sheet material
The fine bumps in face can be crushed in punch process.It is therefore desirable to improve the press formability of raw sheet material.
In this regard, the technology for solving the stamping sex chromosome mosaicism of the raw sheet material is disclosed in patent document 2.
In the technology disclosed in patent document 2, it is formed in the concave-convex form parameter of heat exchange plate surface by regulation, carries
The press formability of plateau plank.In addition, turbulent flow, forced convertion when the protrusion for being formed in raw sheet material promotes to be assembled in heat exchanger
To improve condensation heat transfer.
The condensation heat transfer realized using heat exchanger plates is significantly influenced by the discharge of generation liquid.But utilizing patent
In the concaveconvex shape (lobe shape) for the raw sheet material that the technology of document 2 is formed, generates liquid and moisten extension because of surface tension, because
This, the effect that discharge generates liquid is sometimes lower than imagination (discharge rate for generating liquid tails off).That is, using using
Raw sheet material that the technology of patent document 2 is formed and the heat exchange that manufactures be difficult to improve condensation heat transfer with plate during conductivity of heat.
In addition, the concaveconvex shape formed with the technology of patent document 2 is because height is low and (protrusion is not to connect for the shape of disjunction
Continuous shape), therefore, the disturbance promoting effect in heat exchange plate is sometimes lower than imagination.In addition, the bumps of patent document 2
The contact area of medium of shape when gas is condensed into liquid due to the liquid film generated in condensation process tails off, and condensation is promoted to pass
The effect of heat is sometimes lower than imagination.
That is, the liquid film generated when heat exchanger being made to work makes the heat transfer property for the heat exchange plate for being assembled in the heat exchanger
Decline, therefore, in the raw sheet material for being manufactured as heat exchange plate, needs the liquid film for considering that generation is expeditiously discharged and make the liquid
Film is thinning and designs.
