The specific embodiment
Below, heat exchange elements of the present invention is carried out more specific description.
Among the present invention,, use tube with hollow bulb as with two separate members that the fluid road separates.Blank for tube is not particularly limited, yet in order to separate reliably between two fluid roads, obtains good heat exchanger effectiveness, preferably uses plastics blank or metal stock.In addition, be under the situation of liquid at dehumidifying purposes or fluid, then not ideal enough if there are two humidity exchange or the penetrating of liquid between fluids stream, so used tube is the material of air impermeability and moisture impermeability among the present invention.
The plastics blank can make the thickness attenuation of barrel owing to excellence aspect processability, can improve heat exchanger effectiveness etc., therefore preferred the use.As the concrete example of plastics blank, for example can enumerate acrylic resin, polyvinyl resin, polystyrene resin, (methyl) acrylonitrile styrene butadiene ter-polymer resin (ABS resin), polycarbonate resin, pet resin etc.
Metal stock can improve heat exchanger effectiveness because heat conductivity is good, therefore preferred the use.As the concrete example of metal stock, for example can enumerate aluminium, iron, copper, nickel, stainless steel alloy etc.
For the preferred cross sectional shape of tube, can enumerate closed curve (comprising positive circle, oval-shaped circle), polygonal etc.In polygonal, also comprise as star and see shape with recess from the tube outside.In addition, part or all that forms polygonal limit also can be curve, and part or all that also can make polygonal summit becomes circle.Because processing is easy to, therefore most preferably cross sectional shape is circular.
The thickness of tube wall surface is preferably below the above 1mm of 0.005mm.If the thickness of tube wall surface is less than preferred range, Tong undercapacity then, and then make the undercapacity of heat exchange elements and might can't keep structure.On the other hand, if surpass the scope of the thickness of preferred tube wall surface, then might cause the reduction of heat exchanger effectiveness.The thickness of tube wall surface is to be determined by (external diameter-internal diameter of tube).
Heat exchange elements of the present invention is that the veneer that tube is arranged in parallel is provided with the element that the compartment of terrain is laminated.Under the situation that tube is arranged in parallel, if make each in the same plane haply, then the pressure loss on the second fluid road will become still less, thereby preferred.
Fig. 1～3rd, an example of the veneer that tube 18 is arranged in parallel.At interval both can be as shown in Figure 1 between tube in the veneer and the tube, interval (zero) can not be provided with at interval shown in Fig. 2 and 3 yet.Both can be constant (Fig. 2) at interval, also can be different (Fig. 3).Wherein, if at interval constant, then fluid stream just can be partial to the specific part on fluid road, can stabilisation, thereby preferred.If the mean value at the interval in certain veneer is made as " equispaced ", then the external diameter with tube is made as 1, and the equispaced is preferably below 5.If the equispaced surpasses this value, heat exchanger effectiveness just might reduce.
Tube is parallel to each other in each veneer inside, and when stacked, tube is parallel to each other.This is because fluid stream can be partial to the specific part on fluid road, can stabilisation.For the compartment of terrain is set that veneer is stacked, can utilize the distortion of the part of the tube that constitutes veneer, also can use distance piece.In addition, can also utilize the parts or the structure of the portion that is provided with that uses the heat exchange elements in the devices such as air regulator that heat exchange elements of the present invention makes.In addition, also can be their combination.
To using the stacked situation of distance piece to describe.Distance piece be with keep in each veneer tube to be arranged in parallel and to form the second fluid road be that main purpose is used, and then play the structure-preserved effect of heat exchange elements monomer.As long as distance piece can satisfy the intensity of machinery, keep the structure of heat exchange elements, just be not particularly limited for material or shape.As material, can use plastics blank, metal stock, blank wooden (timber, paperboard etc.), ceramic batch etc.Bonding for distance piece and veneer, it is easy utilizing the bonding of bonding agent, yet is that it is bonding also can to utilize hot melt to fetch under the situation of plastics of thermal fusible in any one party of tube or distance piece.
Fig. 4 is the single hop 20 of the bonding veneer that tube 18 is arranged in parallel on distance piece 19.Fig. 5 is the heat exchange elements 21 that this single hop 20 is laminated.Fig. 6 is the perspective view of the heat exchange elements 21 of Fig. 5 of seeing along the arrow A direction.Fig. 7 is the perspective view of the heat exchange elements 21 of Fig. 5 of seeing along the arrow B direction.In this heat exchange elements 21, the hollow bulb of tube 18 is first fluid roads 23, and among Fig. 5, first fluid flows along the arrow B direction.In addition, the space that is marked off by distance piece 19 in the outside of tube 18 is second fluid roads 24, and among Fig. 5, second fluid flows along the arrow A direction.As shown in Figure 7, forming under the situation in gap 22, between tube 18 and the distance piece 19 preferably with its filling.As the method for filling gap 22, has with the form fit of tube 18 concavo-convex the method that do not form the method for the distance piece in gap 22, stop up with putty or bonding agent etc. thereby can enumerate to use.
Fig. 8 is the heat exchange elements 21 that the flat board that will offer the hole that is fit to tube 18 external diameter uses as distance piece 19.Between distance piece 19 and tube 18, can not form the gap.In this heat exchange elements 21, the hollow bulb of tube 18 is first fluid roads, and first fluid flows along the arrow B direction.In addition, the space that is marked off by distance piece 19 in the outside of tube 18 is second fluid roads, and second fluid flows along the arrow A direction.
The number of distance piece is not particularly limited, so long as get final product more than 1.Consider from structure-preserved viewpoint, be preferably more than 2.The width of each distance piece both can be identical when above to be 2 at distance piece, also can be different.For the width of distance piece, be made as 1 o'clock at width 40 the second fluid road, be preferably more than 0.001 below 0.3 more preferably (Fig. 6) below 0.3 more than 0.01.Here, the width of so-called distance piece is under 1 the situation at distance piece, is meant the width of this distance piece.Under distance piece is a plurality of situation, be meant the summation of the width of each distance piece.For example, among Fig. 6, have 2 distance pieces, as the width of each distance piece and (39a+39b) become the width 39 of distance piece.If the width of distance piece less than preferred range, then might can't obtain enough mechanical strengths of heat exchange elements.On the other hand, if surpass preferred range, then might cause the rising of the pressure loss on the second fluid road.
For the influence that makes the width that reduces the second fluid road tails off, distance piece also can have the hollow space parallel with the direction on the second fluid road.For example, can enumerate will have the tube of hollow bulb situation about using etc. as distance piece.
The interval between the tube in the veneer and the configuration place of distance piece impact the fluid stream in the second fluid road.Consider from the convenient of design of heat exchange elements, under the most situation, distance piece 19 (Fig. 4) is set orthogonally with tube 18.In addition, under being spaced apart zero the situation of the tube in veneer between 18, the fluid stream in the second fluid road flows along the long axis direction (arrow A direction) of distance piece 19, with the direction quadrature on first fluid road in the tube 18.Wanting flow direction to be set under the quadrature situation in addition, as long as come configuration space spare 19 (Fig. 9) according to major axis that makes distance piece 19 and the mode that tube 18 forms quadratures angle in addition with first and second fluid road.
Under the interval between the tube in veneer and the situation of non-zero, can regard the second fluid road as 2.Figure 10 is the perspective view of seeing from the entrance side on first fluid road in the heat exchange elements that veneer shown in Figure 2 is laminated.Distance piece is also not shown.One of the second fluid road is the fluid road (arrow A) of flowing abreast with veneer 20.Another is to pass the interval of the tube 18 in the veneer and the fluid road (arrow C) of running through each veneer.In addition, also can utilize two fluid roads simultaneously.Their selection is according to the relation decision of the position of the entrance and exit on the second fluid road in the heat exchange elements.
In the second fluid road, the mode by the position near the entrance side on first fluid road and outlet side is limited disposes the entrance and exit on the second fluid road respectively, also the first and second fluid streams can be made as convection current.
Run through under the situation of each veneer on the second fluid road, can select the position relation of the compartment of compartment between the tube in the veneer and adjacent veneer.As shown in figure 10, if the mode that between adjacent veneer, overlaps according to the compartment between the tube 18, entrance side from the first fluid road, if with tube 18 with right angle grid alignment arrangements, then flowing of arrow A and arrow C just all becomes flowing of straight line, can obtain the second low fluid road of the pressure loss.Figure 11 and 12 also is the perspective view of the heat exchange elements seen from the entrance side on first fluid road.As shown in figure 11, if the mode that between adjacent veneer, does not overlap according to the compartment between the tube 18, entrance side from the first fluid road, with tube 18 with sawtooth grid alignment arrangements, then flow and to be hindered and produce turbulent flow, fluid stream will spend the longer time by the second fluid road, and it is good that heat exchanger effectiveness becomes.As shown in figure 12, also can be in the arrangement of the different arrangement of 2 sizes that mix to have tube 18 more than the position or the compartment between the tube 18 etc.These arrangements can suitably be distinguished use according to the application target of heat exchanger.
Come under the stacked situation in the distortion that utilizes tube, the effect that keeps the interval between veneer is played in this distortion.As concrete example, the part that can enumerate tube become the situation of overshooting shape on the stacked short transverse.More preferably this projection is the spatial division of the outside of tube to be played the shape of the effect that forms the second fluid road.Can utilize and add hot-working or punch process and make the tube distortion.
The parts of the portion that is provided with of the heat exchange elements in utilizing the devices such as air regulator that use heat exchange elements of the present invention or structure are provided with under the situation at interval, these parts or structure are used with the appearance identical with distance piece, can obtain the effect of the formation on formation at interval and maintenance, the second fluid road.
