Abstract
The invention relates to a sheet bar for a full-welded plate type heat exchanger and a heat exchanger using the sheet bars. The sheet bar for the full-welded plate type heat exchanger is a rectangular sheet bar, wherein a plurality of individual vertically-arranged bar-shaped grooves and a plurality of individual transversely-arranged bar-shaped bumps are arranged on the sheet bar; and round reinforced grooves or bumps are arranged between each two adjacent bar-shaped groove and each two adjacent bar-shaped bumps. According to the heat exchanger using the sheet bars, the sheet bars are positively and negatively overlapped from top to bottom; the both left and right edges of a first sheet bar and a second sheet bar are respectively welded in a sealing manner; the both front and back edges of the second sheet bar and a third sheet bar are respectively welded in the sealing manner; the both left and right edges of the third sheet bar and a fourth sheet bar are respectively welded in the sealing manner, and so on. The rigidity, the precision and the thermal efficiency are high.
Description
Technical field
The present invention relates to a kind of heat-exchanger rig, belong to full-welding plate-type heat exchanger, be used for fixed head all welded type heat-exchange apparatus or the parts of two kinds of exchange medias.
Background technology
Along with country in recent years to environmental protection, reduce thermal pollution, improve environment, save the raising of energy requirement and the maximization of thermoelectricity, nuclear power oil, chemical industry, oil refining and smelting device, the heat exchange efficiency of heat exchanging product, temperature tolerance, resistance to pressure are had higher requirement.
Plate-type heat exchanger slab exists precision on the low side at present, the shortcoming of intensity, insufficient rigidity and plate warpage, cause pressure strip in the process that compresses, to need to overcome the load that plate warpage, local gross distortion etc. apply, directly affect the size of the diameter of pressure strip and fishbolt.Because plate is out of shape after moulding seriously, need to carry out the secondary cutting edge, causes raw-material waste.The uniform property of side direction of plate type heat exchanger medium is relatively poor at present, easily causes flow blind angle, and heat transfer efficiency is low.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of full-welding plate-type heat exchanger plate and use the heat exchanger of this plate, its rigidity, precision, the thermal efficiency are high.
The present invention solves the technical scheme that its technical problem takes: a kind of full-welding plate-type heat exchanger plate is the plate of rectangle, the strip groove a plurality of independent of each other of longitudinal arrangement and transversely arranged strip projected parts a plurality of independent of each other are arranged on the plate, circular reinforcement groove or projection are arranged between described per two adjacent strip grooves and per two adjacent strip projected parts.
A kind of heat exchanger that uses described plate, plate is positive and negative superimposed, and from falling down, first and second sheet the right and left is seal welding respectively, both sides seal welding respectively before and after second and third sheet, third and fourth sheet the right and left is seal welding respectively, and the rest may be inferred.
1), plate rigidity, precision is high the present invention has following advantages:, thereby reduce the thickness of clamping plate and the diameter of fishbolt; 2), a blanking of plate, can satisfy matching requirements, reduce the secondary cut amount that plate is shaped; 3), the length of plate and width can adjust as required; 4), after assembly welding becomes plate bundle or plate pipe, flow diameter is widened, and reduces fouling, easy to clean; 5), adopt the heat exchanger fluid of this plate under very low Reynolds, to form turbulent flow, improve heat exchange efficiency, save heat exchange area, dwindle the volume of heat exchanger, reduce the operation cost of manufacturing cost and equipment.

The specific embodiment
As shown in drawings,
A kind of full-welding plate-type heat exchanger plate is the plate of rectangle, and the strip groove 3 a plurality of independent of each other of longitudinal arrangement and transversely arranged strip projected parts 1 a plurality of independent of each other are arranged on the plate.Described per two adjacent strip grooves 3 and 1 of per two adjacent strip projected parts have circular reinforcement groove 4 or strengthen projection 2.
Described strip groove 3 or strip projected parts 1 be shaped as rectangle that ellipse, dumbbell shape, two ends are circular arcs or trapezoidal.
The length of described strip groove 3 is 10-40mm, the length direction of strip groove 3 and horizontal angle are 15-30 °, the side of strip groove 3 and the angle of vertical line are 50-60 °, and the distance of adjacent strip groove 3 is 20-30mm, and the degree of depth of strip groove 3 is 2-5mm.
The length direction of described strip projected parts 1 and the angle of vertical line are 15-30 °, and other parameters are identical with described strip groove 3.
Described reinforcement groove 4 or to strengthen protruding 2 diameters be φ 5-8mm, the degree of depth or highly be 0.5-1mm.
A kind of heat exchanger that uses described plate, plate is positive and negative superimposed, and from falling down, first and second sheet the right and left is seal welding respectively, both sides seal welding respectively before and after second and third sheet, third and fourth sheet the right and left is seal welding respectively, and the rest may be inferred.
