FIG. 1 is a perspective view schematically showing a packed sheet 1 for a cooling tower according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II in FIG.

Referring to Fig. 1, the filling sheet 1 for a cooling tower according to the present embodiment has a hill 10 and a valley 20. These crests 10 and valleys 20 are alternately located in the first direction (+ x direction). Of course, the peak portions 10 and the valleys 20 are alternately located in the second direction (+ y direction) intersecting with the first direction (+ x direction).

A hollow protruding portion 30 is formed on the first surface S1 of at least one of the hill 10 and the valley 20. A groove 40 is formed on the second surface S2 of at least one of the hill 10 and the valley 20. The thickness of each of the peak 10, valleys 20, protrusions 30, and grooves 40 may be substantially the same. That is, the packed sheet for cooling tower according to this embodiment can be understood as a sheet having substantially the same thickness in each portion.

1 and 2, both the protruding portion 30 and the groove portion 40 are formed on the crest 10, that is, the first surface S1 and the second surface S2 as described above are the same surface However, it should be understood that the present invention is not limited thereto and various modifications are possible. The projecting portion 30 and the groove portion 40 may be formed in the valley portion 20 instead of the peak portion 10 and either one of the projecting portion 30 and the groove portion 40 may be formed in the peak portion 10, Or may be formed in the valley portion 20. 1 and 2, both the protrusion 30 and the groove 40 are formed on the crest 10, but both the protrusion 30 and the groove 40 may be formed on the crest 20 as well.

Here, the first surface S1 or the second surface S2 does not necessarily have to be a flat surface, it may be a curved surface, and a part may be somewhat rugged. 2, not only the first surface S1 and the second surface S2 appear flat on the sectional view but also a recessed portion in the vicinity of the protruding portion 30 and / or the groove portion 40 in addition to the flat portion, As shown in FIG.

1, the same shape is repeated. Therefore, when a plurality of the above-mentioned cooling tower packing sheets 1 are used, air and / or cooling water moves inside A filling sheet laminate for a cooling tower can be realized. 3 is a schematic side view showing a part of a packed sheet laminate for a cooling tower using the packed sheets 1 for cooling towers of FIG.

In the case of Fig. 3, for example, a filling sheet 1 for a cooling tower as shown in Fig. 1 is placed on the lower side, and a filling sheet 2 for a cooling tower having the same shape is placed on the upper side, And the protruding portion of the cooling tower charging sheet 1 is inserted into the groove of the cooling tower charging sheet 2 to form the cooling tower charging sheet 1 and the cooling tower 1, It can be understood that the charging sheet 2 for the first embodiment is mutually coupled. The protruding portion 30 and the groove portion 40 are alternately arranged in the first direction (+ x direction) of the filling sheet 1 for the cooling tower and the filling sheet 2 for the cooling tower as shown in Figs. 1 and 3 The filling sheet 1 for the cooling tower and the filling sheet 2 for the cooling tower are mutually combined at a plurality of positions so that the high bonding force between the cooling sheet 1 and the cooling tower filling sheet 2 can be secured can do. In particular, when the filling sheets 1 for cooling towers are coupled to each other, the filling sheets 1 for the cooling tower are roughly arranged and pressed slightly so that the projections 30 and the groove portions 40 face each other.

Of course, another filling sheet for cooling towers (not shown) may be placed in the lower part of the filling sheet 1 for the cooling tower and bonded to the filling sheet 1 for the cooling tower in the same manner. Fig. 4 is a cross-sectional view taken along the line IV-IV in Fig. 1, in which a protrusion 30 is formed on the first surface S1 of the valley 20, And a groove 40 is formed on the second surface S2. When another filling sheet for the cooling tower located at the lower portion of the filling sheet 1 for the cooling tower is to be bonded to the filling sheet 1 for the cooling tower, the protrusions or grooves of the filling sheet 1 for the cooling tower shown in Figs. The protruding portion 30 or the groove portion 40 such as shown in Fig. 4 positioned adjacent to the second direction (+ y direction) of the protruding portion or the groove portion is engaged with the groove portion or the protruding portion of the other cooling tower- .

That is, the protruding portion 30 is formed along the second direction (+ y direction) of the packed sheet for cooling tower 1 so that the protruding direction of the protruding portion 30 along the second direction (+ y direction) Direction and the -z direction). Of course, the groove portion 40 is also formed along the second direction (+ y direction) so that the recessed direction of the groove portion 40 along the second direction (+ y direction) . Whereby a plurality of packing sheets for cooling towers are mutually coupled, thereby realizing a packed sheet laminate for a cooling tower in which a space (SP, see FIG. 3) in which air and / or cooling water can be moved therebetween is secured.

Conventionally, in order to make such a packed sheet for a cooling tower, the packed sheets for the cooling tower were bonded together using an adhesive. These adhesives have various problems such as being harmful to the human body and weak in flame. However, when the packed sheet for a cooling tower according to the present embodiment is used, it is eco-friendly because it does not use an adhesive which may be harmful to the environment. Further, when the filling sheets 1 for cooling towers are joined to each other, the filling sheets 1 for the cooling towers are roughly arranged and pressed slightly so that the projections 30 and the groove portions 40 face each other, Can readily bond the charge sheets for the cooling tower. In particular, since no separate equipment or device is required in the combining process, and simply pressing each other is required, the formation process of the filling sheet laminate for cooling tower is simplified, and the formation cost can be drastically reduced.

FIG. 5 is an enlarged sectional view schematically showing the portion A of FIG. 2, that is, the protruding portion 30, and FIG. 6 is an enlarged sectional view schematically showing the portion B of FIG. As shown in Fig. 3, when the packed sheet for cooling tower 1 and the packed sheet for cooling tower 2 are combined, it is necessary to prevent their mutual separation because of their excellent bonding strength. For this purpose, the plane (xy plane) defined by the first direction (+ x direction) and the second direction (+ y direction) The cross sectional area 34A in the reference plane (xy plane) is larger than the cross sectional area 44A in the reference plane (xy plane) of the second extended portion 44 corresponding to the first extended portion 34 as a part of the groove 40 ).

Thus, when the protruding portion 30 of the one-cooling tower charging sheet is inserted into the groove portion 40 of the other cooling tower charging sheet, the protruding portion 30 is brought into close contact with the groove portion 40, The portion 34 is brought into close contact with the second extended portion 44 of the groove portion 40 so that it is possible to effectively prevent the charge sheets for the cooling tower, which are mutually coupled due to the mutual frictional force, from being separated from each other. Of course, the projections 30 and / or the grooves 40 may have a flexible characteristic or elasticity so as to smoothly insert the projections 30 into the grooves 40. In some cases, At least a part of the groove 30 may be collapsed and inserted into the groove 40.

5 and 6, the area 36A of the first end face 36 farthest from the first surface S1 of the protrusion 30 is greater than the area 36A of the second surface 34 of the groove 40 The area 46A of the second end face 46 (bottom face) farthest from the first end face 46 (S2). If the area 36A of the first end face 36 of the protrusion 30 is greater than the area 46A of the second end face 46 of the groove 40 then at least a portion of the protrusion 30 is deformed The first end face 36 of the projection 30 may not be able to contact the second end face 46 of the groove 40 when the charge sheets for the cooling tower are bonded together. In this case, the distance between the adjacent cooling towers for the cooling tower can not be kept constant.

The area 36A of the first end face 36 of the projecting portion 30 is equal to or less than the area 46A of the second end face 46 of the groove 40 in the case of the cooling tower charging sheet according to the present embodiment. Thus, by engaging the packing sheets for cooling towers of this structure with one another, the first end surface 36 of the protrusion 30 can be in contact with the second end surface 46 of the groove 40, The distance between the charge sheets can be kept constant.

The first surface S1 of the protruding portion 30 may be formed in the area of the first end surface 36 of the protruding portion 30 even if the area 36A of the first end surface 36 is equal to or smaller than the area 46A of the second end surface 46 of the groove portion 40. [ Sectional area 32A in the reference plane (xy plane) closest to the second surface S2 of the groove 40 is larger than the sectional area 42A in the reference plane (xy plane) closest to the second surface S2 of the groove 40 . When the projecting portion 30 of the one-cooling tower charging sheet is inserted into the groove portion 40 of the other cooling tower charging sheet, the projecting portion 30 is brought into close contact with the groove portion 40, It is possible to effectively prevent the charging sheets for separating from each other. The first extended portion 34 of the protruding portion 30 is brought into close contact with the second extended portion 44 of the groove portion 40 so that the coupling between the filling sheets for the cooling tower can be reliably maintained. Of course, the projections 30 and / or the grooves 40 may have a flexible characteristic or elasticity so as to smoothly insert the projections 30 into the grooves 40. In some cases, At least a part of the groove 30 may be collapsed and inserted into the groove 40.

As shown in FIG. 5, the shape of the protruding portion 30 is the same as the protruding portion 30 of the first surface S1, which is the farthest from the first surface S1, The cross sectional area of the protruding portion 30 in the reference plane (xy plane) and the planes parallel to this reference plane can be gradually reduced toward the side surface 36. Of course, the degree of reduction of the cross-sectional area may vary depending on the portion of the protrusion 30 in this process. (Xy plane) from the portion closest to the first surface S1 of the protrusion 30 to the first enlarged portion 34 is smaller than the extent of the sectional area in the reference plane The degree to which the cross-sectional area at the reference plane (xy plane) decreases until reaching the first end face 36 may be smaller.

As shown in FIG. 6, the shape of the groove portion 40 may be formed in the groove portion 40 from the portion closest to the second surface S2 of the groove portion 40, The cross sectional area of the groove 40 in the reference plane (xy plane) and the planes parallel to the reference plane can be gradually reduced toward the side surface 46. Of course, the extent of the reduction of the cross-sectional area may vary depending on the portion of the groove 40 in this process. The distance from the second extending portion 44 to the second extending portion 44 is smaller than the degree of reduction in the cross-sectional area in the reference plane (xy plane) from the portion closest to the second surface S2 of the groove portion 40 to the second extending portion 44, The degree to which the cross-sectional area at the reference plane (xy plane) decreases until reaching the second end face 46 may be smaller.

When the protruding portion 30 of the one-cooling tower packed sheet is inserted into the groove portion 40 of the other cooling tower filling sheet, the insertion of the one cooling tower filling sheet is smoothly performed . The protruding portion 30 and the groove portion 40 have a relatively small cross sectional area as described above so that when the protruding portion 30 of the one cooling tower charging sheet is inserted into the groove portion 40 of the other cooling tower charging sheet It is possible to effectively prevent the charging sheets for cooling towers, which are coupled to each other due to the mutual frictional force, from being separated from each other by allowing the protruding portions 30 to sufficiently adhere to the groove portion 40 while allowing the insertion to proceed smoothly.

In FIGS. 5 and 6, the protruding portion 30 and the groove 40 gradually decrease in cross sectional area toward the first end surface 36 and the second end surface 46, but the present invention is limited to this no.

For example, from the portion closest to the first surface S1 of the protrusion 30 to the first enlarged portion 34, the protrusion 30 in the reference plane (xy plane) and the planes parallel to this reference plane So that the cross-sectional area of the cross section can be gradually reduced. And from the first extending portion 34 to the first end face 36 farthest from the first surface S1 of the projection 30, the distance between the reference plane (xy plane) and the plane parallel to the reference plane The cross-sectional area of the protruding portion 30 of the protruding portion 30 can be gradually reduced. However, in at least a portion of the first extended portion 34 of the protrusion 30, the cross-sectional area of the protrusion 30 in the reference plane (xy plane) and the planes parallel to this reference plane may be constant.

The groove 40 may also be similar. For example, from the portion closest to the second surface S2 of the groove portion 40 to the second extending portion 44, the groove portion 40 in the reference plane (xy plane) and the planes parallel to the reference plane, So that the cross-sectional area of the cross section can be gradually reduced. And from the second extending portion 44 to the second end face 46 farthest from the second surface S2 of the groove portion 40, the distance between the reference plane (xy plane) and the planes parallel to the reference plane The cross-sectional area of the groove 40 of the groove 40 can be gradually reduced. However, in at least a portion of the second extended portion 44 of the groove 40, the cross-sectional area of the groove 40 in the reference plane (xy plane) and the planes parallel to this reference plane may be constant.

Of course, the shapes of the projections 30 and the grooves 40 may be modified in various other ways. In any case, from the portion closest to the first surface S1 of the projections 30, The cross sectional area of the protruding portion 30 in the reference plane (xy plane) and the planes parallel to the reference plane can be prevented from increasing. In the case of the groove portion 40 as well, from the portion closest to the second surface S2 to the second end surface 46 of the groove portion 40, the distance from the reference plane (xy plane) The cross-sectional area of the groove portion 40 can be prevented from increasing. This is for the convenience of storage and transport of the charge sheets 1 for the cooling tower.

When the projecting portion 30 of the one-phase cooling tower charging sheet is inserted into the groove portion 40 of the other cooling tower charging sheet to form the filling sheet stack for cooling tower, as shown in FIG. 3, 1 and 2, a space SP through which air and / or cooling water can move is formed. However, in the case of storing or transporting the charge sheets 1 for the cooling towers before forming the charge sheet laminate for cooling towers, it is preferable that there is no space between the charge sheets 1 for the cooling towers, Do.

When the charge sheets 1 for the cooling tower are stored or transferred prior to forming the charge sheet laminate for cooling tower, the projections 30 of the charge sheet for one cooling tower are inserted into the back surface of the projections 30 of the other cooling tower And attempts to reduce the overall volume of the filling sheets for the cooling tower in such a manner that the back surface of the groove portion 40 of the filling sheet for the other cooling tower is inserted into the groove portion 40 of the filling sheet for one cooling tower. (Xy plane) and planes parallel to this reference plane, while moving from the portion closest to the first surface S1 of the protrusion 30 to the first end face 36 of the protrusion 30 The protruding portion 30 of the filling sheet for one cooling tower is not closely attached to the back surface of the protruding portion 30 of the filling sheet for the other cooling tower so that the filling sheet for cooling towers The overall volume is greatly increased. From the portion closest to the second surface S2 of the groove portion 40 to the second end surface 46 of the groove portion 40, the surface of the groove 40 in the reference plane (xy plane) The back surface of the groove portion 40 of the filling sheet for the other cooling tower is not closely attached to the groove portion 40 of the one cooling tower charging sheet, The overall volume is greatly increased. However, in the case of the filling sheet for the cooling tower according to the present embodiment, the reference plane (xy plane) is formed from the portion closest to the first surface S1 of the protrusion 30 to the first end surface 36 of the protrusion 30, And the sectional area of the projections 30 on the planes parallel to the reference plane are not increased. Therefore, when storing or transporting the charge sheets for cooling towers before forming the packed sheet stack for cooling towers, the volume thereof is remarkably reduced .

FIG. 7 is a cross-sectional view schematically showing a part of a structure in which two sheets of cooling towers for a cooling tower are combined, and FIG. 8 is an enlarged sectional view schematically showing a part of FIG. 7 and 8, the protruding portion 30 of the packed sheet for cooling tower protruded in the + z direction is joined to the groove portion 40 of the packed sheet for cooling tower which is recessed in the + z direction.

The first end face of the protrusion 30 is formed in the groove 40 (the bottom face of the protrusion 30) as shown in the figure, because the area of the first end face of the protrusion 30 is equal to or narrower than the area of the second end face (Bottom surface) of the first end surface (bottom surface). It is also preferable that the cross sectional area of the first extended portion of the protrusion 30 in the xy plane is larger than the cross sectional area of the second extended portion of the groove 40 The expanded portion is in close contact with the second extended portion of the groove portion 40, so that the bonding force of the filling sheets for the cooling tower can be increased without using an adhesive or the like. At this time, since the cross-sectional area of the first extended portion of the protrusion 30 is larger than the cross-sectional area of the first extended portion of the groove 40 (in the pre-engagement situation), the first extension of the protrusion 30 And the space SP 'may be formed between the vicinity of the first extended portion of the groove 40 and the vicinity thereof. This space SP 'is different from the space SP between the charge sheets for the cooling tower through which the air and / or the cooling water can move, and is not a space to which the air and / or the cooling water can move.

Although the groove portion 40 has been described as having the second extending portion 44 so far, the present invention is not limited thereto. 9, which is a cross-sectional view schematically showing a part of a filling sheet for a cooling tower according to another aspect of the present invention, (Xy plane) and the grooves 40 in the planes parallel to the reference plane (the xy plane) from the portion closest to the first surface S2 to the second end surface 46 farthest from the second surface S2, So that the cross-sectional area of the cross-sectional area gradually decreases (uniformly). Of course, also in this case, the protruding portion 30 of the filling sheet for the cooling tower can have the shape as described above with reference to Fig. 5 and the like. Therefore, when the projecting portion 30 of the one-cooling tower charging sheet is inserted into the groove portion 40 of the other cooling tower charging sheet, the projecting portion 30 is brought into close contact with the groove portion 40, It is possible to effectively prevent the charge sheets from being separated from each other. Of course, the projections 30 and / or the grooves 40 may have a flexible characteristic or elasticity so as to smoothly insert the projections 30 into the grooves 40. In some cases, At least a portion (e.g., the first enlarged portion 34) of the recess 30 may be collapsed to be inserted into the groove 40.

10 is a perspective view schematically showing portions of a charge sheet for a cooling tower according to another aspect of the present invention, that is, protrusions 30 and grooves 40. As shown in Fig.

10, the protruding portion 30 has a depression 38 at the center, and the depressed portion 40 has a protruding support portion 48 at the center. In this case, when the projecting portion 30 of the charge sheet for one cooling tower is inserted into the groove portion 40 of the other cooling tower charging sheet, the projecting support portion 48 of the groove portion 40 is inserted into the recessed portion 38 of the projecting portion 30 Can be inserted. By such a structure, the contact area between the protruding portion 30 and the groove portion 40 is remarkably widened, so that it is possible to effectively prevent the charging sheets for the cooling tower, which are coupled to each other due to mutual frictional force, from being separated from each other. Of course, as shown in FIG. 11, which is a perspective view schematically showing a part of a packed sheet for a cooling tower according to another aspect of the present invention, a depression 38 ' The protruding support portion 48 'of the groove portion 40 may divide the groove portion 40 into a first groove portion and a second groove portion which are spaced apart from each other have.

On the other hand, in the embodiments described heretofore or in modifications thereof, the roughness of at least a part of the outer surface (the + z direction outer surface in the case of FIG. 5) of the protruding portion 30 is less than the roughness of at least a part of the first surface S1 It can be rough. Here, the roughness can be understood as a numerical value represented by the root mean square (RMS) of the roughness of each surface. The frictional force between the protruding portion 30 and the groove portion 40 is further increased to increase the bonding force of the cooling tower packing sheets when the protruding portion 30 of the one cooling tower charging sheet is inserted into the groove portion 40 of the other cooling tower charging sheet. . Of course, the roughness of at least a part of the inner surface (the + z direction inner surface in the case of FIG. 6) of the groove 40 can be made rougher than the roughness of at least a part of the second surface S2. The frictional force between the protruding portion 30 and the groove portion 40 is further increased so that the bonding strength of the cooling sheet packing sheets can be enhanced even when the protruding portion 30 of the one-cooling tower packing sheet is inserted into the groove portion 40 of the other cooling- . Of course, the roughness of both the projecting portion 30 and the groove portion 40 can be made rougher than the roughness of the first surface S1 or the second surface S2.

A brief description will be given of a manufacturing method of such a cooling sheet for a cooling tower. A mold having the same or similar shape as the filling sheet for a cooling tower as shown in Fig. 1 is prepared, a thin flat sheet is placed on the top of the mold, The air between the mold and the sheet is pumped and removed while applying heat to the sheet, so that the sheet has the same / similar shape as the upper surface of the mold while closely adhering to the upper surface of the mold. With this method, a packed sheet for a cooling tower can be easily produced. Heat lines may be embedded in the mold to apply heat to the sheet, and a pressure may be applied to the top of the mold to press the sheet toward the mold.
