Description

Technology Field

[0001] The present invention relates to a cooling tower, and more specifically, to a two-in-one modular cooling tower formed in a stacked form for use in cooling water, installed on the rooftop of a building, etc. Background Technology

[0002] Unless otherwise indicated in this specification, the contents described in this identification item are not prior art for the claims of this application, and are not recognized as prior art simply because they are described in this identification item.

[0003] Cooling towers are essential components of industrial and building cooling systems, typically installed on rooftops to release heat and enable the reuse of cooling water. However, in high-rise urban buildings or environments with limited space, cooling towers often need to be designed with a stacked structure.

[0004] Several issues may arise when installing stacked cooling towers. First, cooling towers with a multi-cell structure require a complex piping system, necessitating measures to simplify it. Second, flow distribution issues require separate flow control valves, and failure to optimize these valves can lead to reduced cooling efficiency. Third, in a stacked structure, there is a high likelihood of excessive water loss as cooling water accumulates in the lower layers when operation stops. In particular, if the capacity of the upper layer's water tank is small, the design must ensure that no overflow occurs in the lower layer even when the equipment is shut down.

[0005] These issues are important considerations in the installation and operation of stacked cooling towers, and various technical approaches have been studied to address them. However, these technologies still have room for improvement, and advancements are required, particularly in terms of space utilization and ease of maintenance. Prior art literature

[0006] 1. Patent Document 1: Korean Published Patent Application No. 10-2001-0027988 (Published April 6, 2001) The problem to be solved

[0007] The embodiment of the present invention has been devised to solve the above-mentioned problems and aims to provide a two-in-one modular cooling tower that not only improves space utilization and facilitates maintenance but also reduces overall manufacturing costs. means of solving the problem

[0008] An embodiment of the present invention provides a two-in-one modular cooling tower characterized by comprising: a cooling tower housing including an upper housing having an upper heat exchanger formed therein and a lower housing having a lower heat exchanger formed therein, in order to solve the above-mentioned problem; an upper filling material installed in the upper heat exchanger; a lower filling material installed in the lower heat exchanger; an upper cooling water spray disposed above the upper filling material and spraying cooling water onto the upper filling material; an upper water storage distribution tank installed in the upper housing to store cooling water located below the upper filling material; a lower cooling water spray installed above the lower filling material and communicating with the upper water storage distribution tank; and a lower water storage tank installed in the lower housing to be disposed below the lower filling material.

[0009] It is effective to further include a transfer pipe that supplies cooling water to the upper layer cooling water spray; and a transfer pump installed in the transfer pipe.

[0010] It is preferable that the lower layer cooling water spray sprays the cooling water stored in the upper layer water distribution tank by gravity.

[0011] It is effective to position the lower end of the upper filler relative to the upper end in the direction of the discharge port of the cooling tower housing so as to be inclined overall, and position the lower end of the lower filler relative to the upper end in the direction of the discharge port of the cooling tower housing so as to be inclined overall, and position the lower end of the upper filler so as to protrude more than the upper end of the lower filler in the direction of the discharge port so as to be arranged so that the upper filler and the lower filler are not continuous with each other but are offset from one another.

[0012] The upper layer cooling water spray preferably comprises: a front header formed in a tubular shape with a cooling water inlet; a rear header formed in a tubular shape and spaced apart from the front header; and a plurality of spray tubes, one end of which is connected to the front header and the other end of which is connected to the rear header, with a plurality of spray holes formed through the middle.

[0013] It is effective to further include an adapter comprising a plurality of front insertion holes formed through the front header to be connected to the spray tube, an insertion protrusion having one end fitted into the front insertion hole, and a spray coupling part having the other end connected to one end of the spray tube.

[0014] It is preferable to further include a waterproof packing that is fitted onto the outer surface of the insertion protrusion and seals the space between the front insertion hole and the insertion protrusion.

[0015] It is effective to further include an inspection door installed on the upper housing above the upper cooling water spray, which allows the upper cooling water spray to be inspected from the outside. Effects of the invention

[0016] According to the means for solving the problem of the present invention as described above, various effects including the following can be expected. However, the present invention is not required to exhibit all of the following effects to be valid.

[0017] As described above, the two-in-one modular cooling tower of one embodiment of the present invention has the advantage of simplifying complex piping because, despite having a multi-cell structure with a plurality of heat exchange sections, it does not need to supply cooling water through separate pipes for each section. That is, even though the cooling water inlet is connected only to the upper cooling water spray, the cooling water is supplied sequentially to the lower filling material as well, so there is an advantage that cooling water pipes do not need to be placed in the upper and lower heat exchange sections respectively.

[0018] As a result, since expensive components such as flow control valves for controlling the flow rate supplied to the upper and lower heat exchangers do not need to be used, installation costs can be reduced.

[0019] Since the upper cooling water spray uses a pressure system, a separate reservoir is unnecessary in the upper part of the upper housing, which allows for a reduction in the overall size of the cooling tower. Additionally, even when the system is shut down, the amount of drainage is minimal, preventing cooling water from overflowing to the lower level. Consequently, the size of the upper water distribution tank is also reduced, allowing for a decrease in the overall volume.

[0020] The advantage is that uniform pressure is applied to all spray pipes due to the front and rear headers located on both sides of the upper cooling water spray.

[0021] In addition, the spray tube can be easily attached to and detached from the front header and rear header using the adapter.

[0022] In addition, the inspection door makes maintenance of the upper cooling water spray easier.

[0023] In addition, the bottom of the upper filler protrudes toward the discharge port more than the top of the lower filler, and by arranging them so that they are not continuous but offset from each other, the left-right length of the entire cooling tower can be prevented from increasing.

[0024] In addition, since the position of the lower cooling water spray can be aligned with the top of the lower filler, heat exchange efficiency can be further increased. Brief explanation of the drawing

Specific details for implementing the invention

[0026] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0027] FIG. 1 is a front view of a two-in-one modular cooling tower according to an embodiment of the present invention, FIG. 2 is a left side view of FIG. 1, FIG. 3 is a top view of FIG. 1, FIG. 4 is an enlarged view of the part where the upper cooling water spray is installed of FIG. 1, and FIG. 5 is an exploded perspective view of part A of FIG. 4.

[0028] As illustrated in these drawings, a two-in-one modular cooling tower of one embodiment of the present invention is a stacked cooling tower and comprises a cooling tower housing (100), an upper layer filler (220), a lower layer filler (210), an upper layer cooling water spray (300), a transfer pipe (700), a transfer pump (600), a lower layer cooling water spray (400), and a blower fan (500).

[0029] The cooling tower housing (100) includes an upper housing (110) in which an upper heat exchanger (111) is formed inside, and a lower housing (120) in which a lower heat exchanger (121) is formed inside. The cooling tower housing (100) is formed in a cuboid shape overall and is stacked in two layers with the lower housing (120) and the upper housing (110). However, it is not limited to this, and may be stacked in multiple layers as needed.

[0030] Based on FIG. 1, an upper intake port (116) is formed through the lower right side of the upper housing (110), and an upper discharge port (117) is formed on the left side. An upper blower fan (510) and a motor to drive it are installed in the lower right side adjacent to the upper intake port (116). An upper guide section (115) is formed on the upper side of the upper blower fan (510) to guide the air introduced through the upper intake port (116) to move smoothly to the upper discharge port (117). An upper heat exchanger (111) is formed in the space between the upper discharge port (117) and the upper guide section (115). An upper filler material (220) is installed in the upper heat exchanger (111).

[0031] A lower intake port (126) is formed through the lower right side of the lower housing (120), and a lower discharge port (127) is formed on the left side. A lower blower fan (520) and a motor to drive it are installed in the lower right side adjacent to the lower intake port (126). A lower guide section (125) is formed on the upper side of the lower blower fan (520) to guide the air introduced through the lower intake port (126) to move smoothly to the lower discharge port (127). A lower heat exchanger (121) is formed in the space between the lower discharge port (127) and the lower guide section (125). A lower filler material (210) is installed in the lower heat exchanger (111).

[0032] An upper layer cooling water spray (300) is positioned on the upper side of the upper layer filler (220) to spray cooling water onto the upper layer filler (220), and cooling water is supplied by a transfer pump (600) through a transfer pipe (700). On the lower side of the upper layer filler (220), an upper layer water distribution tank (113) is installed in the upper layer housing (110) to store cooling water.

[0033] The upper cooling water spray (300) includes a front header (310) formed in a tubular shape, a rear header (320) in a tubular shape spaced apart from the front header (310), and a plurality of spray pipes (330) with a plurality of spray holes (331) formed through them between the front header (310) and the rear header (320). A cooling water inlet (360) is installed on one side of the front header (310) and connected to a transfer pipe (700).

[0034] The front header (310) and the rear header (320) are formed vertically and horizontally as shown in FIG. 3 and are installed parallel to each other with a gap between them. Multiple spray tubes (330) are arranged in a direction that crosses the front header (310) and the rear header (320) and are positioned on the top of the upper layer filler (220).

[0035] A plurality of front insertion holes (311) are formed through the front header (310) to which a spray tube (330) is connected, and the adapter (350) includes an insertion protrusion (351) that fits into the front insertion hole (311) and a spray coupling part (352) that is coupled to one end of the spray tube (330). A waterproof packing (340) that seals the space between the front insertion hole (311) and the insertion protrusion (351) is fitted onto the outer surface of the insertion protrusion (351).

[0036] An inspection door (114) is installed on the upper side of the upper cooling water spray (300) of the upper housing so that the upper cooling water spray (300) can be inspected from the outside.

[0037] A lower layer filler (210) is installed in the lower layer heat exchanger (121). Additionally, a lower layer cooling water spray (400) is installed on the upper side of the lower layer filler (210) and is connected to the upper layer water distribution tank (113), and a lower layer water tank (123) is installed in the lower layer housing (120) on the lower side of the lower layer filler (210).

[0038] The lower cooling water spray (400) has a structure in which it is sprayed by the gravity of the cooling water stored in the upper water distribution tank (113). That is, it has a structure in which it is sprayed downward by the gravity of the cooling water stored in the upper water distribution tank (113) itself, without a separate pressure-applying pipe being connected. The lower cooling water spray (400) is installed in the upper housing in the same way as the upper water distribution tank (113). The lower cooling water spray (400) is positioned to be located above the lower filling material (210). That is, when the upper end of the lower filling material (210) is positioned so as to be offset from the lower end of the upper filling material (200), the lower cooling water spray (400) is positioned in the upper water distribution tank (113) at a position offset from the upper end of the lower filling material (210). As a result, the heat exchange efficiency of the lower filling material (210) can be increased.

[0039] A cooling water discharge port (128) is formed at one end of the lower reservoir (123) and connected to a transfer pipe (700). As a result, the cooling water stored in the lower reservoir (123) is supplied to the load (800), heated through heat exchange with the load, then flows into the cooling water inlet (360) and is supplied to the upper cooling water spray (300).

[0040] The upper layer filler (220) and the lower layer filler (210) are each positioned such that their lower ends are located toward the discharge port of the cooling tower housing (100) relative to their upper ends, and are arranged so that the lower end of the upper layer filler (220) protrudes toward the discharge port more than the upper end of the lower layer filler (210), so that they are arranged so as not to be continuous with each other but offset.

[0041] By arranging it in this way, the left-right length of the entire cooling tower can be prevented from increasing based on Figure 1.

[0042] As described above, the two-in-one modular cooling tower of one embodiment of the present invention has the advantage of simplifying complex piping because, even though it has a multi-cell structure having a plurality of heat exchange sections, it does not need to supply cooling water through separate pipes for each section. That is, even though the cooling water inlet (360) is connected only to the upper cooling water spray (300), the cooling water is sequentially supplied to the lower filling material (210), so there is an advantage that cooling water does not need to be placed in the upper and lower heat exchange sections respectively.

[0043] As a result, since expensive components such as flow control valves for controlling the flow rate supplied to the upper and lower heat exchangers do not need to be used, installation costs can be reduced.

[0044] Since the upper cooling water spray uses a pressure system, a separate reservoir is unnecessary in the upper part of the upper housing, which allows for a reduction in the overall size of the cooling tower. Additionally, even when the system is shut down, the amount of drainage is minimal, preventing cooling water from overflowing to the lower level. Consequently, the size of the upper water distribution tank is also reduced, allowing for a decrease in the overall volume.

[0045] The advantage is that uniform pressure is applied to all spray pipes due to the front and rear headers located on both sides of the upper cooling water spray.

[0046] In addition, the spray tube can be easily attached to and detached from the front header and rear header using the adapter.

[0047] In addition, the inspection door makes maintenance of the upper cooling water spray easier.

[0048] Although preferred embodiments of the present invention have been described illustratively above, the scope of the present invention is not limited to such specific embodiments and can be appropriately modified within the scope described in the claims. Explanation of the symbols
