Description

Technical Field

[0001] This invention relates to a cooling tower device, and more particularly to a cooling tower device for discharging cooled fluid and its refrigeration unit. Prior Technology

[0002] Existing cooling towers can introduce high-temperature fluids and evaporate the fluid or water vapor in the fluid as it passes through the packing layer (or heat sink) of the cooling tower, thereby cooling the fluid into a cooled fluid and discharging it from the cooling tower to achieve a cooling effect. However, although existing cooling towers can achieve a cooling effect through water vapor evaporation, the cooling efficiency is limited due to the limited evaporation effect. Therefore, how to improve the cooling efficiency is the focus of current cooling tower developers. Summary of the Invention

[0003] Therefore, the object of the present invention is to provide a refrigeration unit with improved refrigeration efficiency.

[0004] Therefore, the cooling unit of the present invention includes a circulation pipe and a plurality of heat dissipation plates. The circulation pipe is adapted to guide the circulation of a refrigerant. The heat dissipation plates are connected to the circulation pipe and arranged at intervals. The outer surfaces of two adjacent heat dissipation plates together define a cooling channel suitable for fluid passage. The hollow interior of each heat dissipation plate forms an internal space suitable for the passage of the refrigerant. When the refrigerant passes through the internal space, the heat dissipation plates exchange heat with the refrigerant, and an ice layer is formed on the outer surface of each heat dissipation plate, so that the heat energy of the fluid passing through the cooling channel is absorbed by the ice layer and cooled.

[0005] In some embodiments, the heat dissipation panels are arranged at intervals along a front-to-back direction. Each heat dissipation panel has two panels arranged front-to-back that together define the internal space.

[0006] In some embodiments, each of the plates has a main body portion and a peripheral portion connected to the periphery of the main body portion. The main bodies of each heat dissipation plate are spaced apart from each other in the front-back direction, and the peripheral portions of each heat dissipation plate are in contact with each other.

[0007] In some embodiments, each plate also has a plurality of recessed solder joints formed in an array on the outer surface of the main body of the plate. The solder joints of the two plates of each heat dissipation layer are aligned and abutted against each other in the front-back direction. The solder joints of each heat dissipation layer divide the internal space into a plurality of transverse channels extending in a left-right direction and a plurality of longitudinal channels extending in a vertical direction, the longitudinal channels connecting to the transverse channels.

[0008] In some embodiments, the circulation piping includes an inlet pipe assembly and an outlet pipe assembly. The inlet pipe assembly is connected to the bottom of the heat dissipation plates and is adapted to guide the refrigerant into the internal spaces. The outlet pipe assembly is connected to the top of the heat dissipation plates and is adapted to guide the refrigerant out of the internal spaces.

[0009] In some embodiments, the inlet pipe assembly and the outlet pipe assembly are respectively connected to the left and right sides of the heat dissipation plates.

[0010] In some embodiments, the cooling unit further includes two heat dissipation pipe assemblies spaced apart in a front-to-back direction. The heat dissipation plates are spaced apart along the front-to-back direction and located between the heat dissipation pipe assemblies. Each heat dissipation pipe assembly is connected to the circulation pipe and has multiple heat dissipation tubes spaced apart and extending in a vertical direction. The interior of each heat dissipation tube is adapted for the passage of refrigerant. The heat dissipation tubes of each heat dissipation pipe assembly collectively define a side cooling space adapted for the passage of fluid. When the refrigerant passes through the interior of the heat dissipation tubes, the heat dissipation tubes exchange heat with the refrigerant, and another ice layer forms on the outer surface of each heat dissipation tube, such that the heat energy of the fluid passing through the side cooling space is absorbed by the other ice layer and cooled.

[0011] In some embodiments, each heat sink assembly further includes a lower connecting plate and an upper connecting plate respectively connected to the upper and lower ends of the heat sink components of the respective heat sink assembly. The lower connecting plate is connected to the inlet pipe assembly, and the interior of the lower connecting plate is adapted to allow the refrigerant from the inlet pipe assembly to pass through. The upper connecting plate is connected to the outlet pipe assembly, and the interior of the upper connecting plate is adapted to guide the refrigerant from the heat sink components to the outlet pipe assembly.

[0012] Therefore, another object of the present invention is to provide a cooling tower device having the aforementioned refrigeration unit.

[0013] Therefore, the cooling tower device of the present invention includes an insulated outer shell and at least one cooling unit. The insulated outer shell defines an accommodating space. The cooling unit is disposed in the accommodating space.

[0014] In some embodiments, the cooling unit is capable of controlling the formation of such ice layers during off-peak power periods and supplying the fluid for cooling during off-peak power periods.

[0015] In some embodiments, the cooling tower assembly includes multiple cooling units. These cooling units are disposed within the accommodating space and stacked vertically. Each cooling unit also includes a support frame. Each support frame includes a frame body accommodating the corresponding heat dissipation plates, and at least four limiting members extending upward from the four corners of the top of the frame body. The frame body of the lower support frame supports the frame body of the upper support frame, and the at least four limiting members of the lower support frame abut against the front, rear, left, and right sides of the frame body of the upper support frame, preventing the upper support frame from moving forward, backward, left, or right.

[0016] In some embodiments, each support frame includes eight limiting members. The eight limiting members of the lower support frame are arranged in pairs against the front, rear, left, and right sides of the frame body of the upper support frame. Each support frame also includes four hanging members. The four hanging members of each support frame are respectively connected to four of the limiting members located at the four corners of the top of the frame body. The four hanging members of each support frame are adapted for hooking by a crane, allowing the corresponding refrigeration unit to be lifted and moved by the crane.

[0017] The advantages of this invention are: by forming ice layers in the cooling channels using the heat dissipation plates, the fluid passing through the cooling channels can exchange heat with the ice layers and be cooled, thereby improving cooling efficiency. Furthermore, by controlling the formation of the ice layers during off-peak power periods using at least one cooling unit and allowing the fluid to pass through for cooling during off-peak power periods, the cooling tower device can also achieve energy savings.

Implementation

[0019] Referring to Figures 1 and 2, an embodiment of the cooling tower device 100 of the present invention is shown. For ease of explanation, directional terms used in the following description of the cooling tower device 100 are defined according to the environment in which it is used. Specifically, in Figure 1, the arrow pointing in the front (X) direction points to the front of the cooling tower device 100, and the opposite direction points to the rear; the arrow pointing in the right (Y) direction points to the right side of the cooling tower device 100, and the opposite direction points to the left; the arrow pointing in the top (Z) direction points to the top of the cooling tower device 100, and the opposite direction points to the bottom. The cooling tower device 100 is suitable for cooling fluids (not shown, such as hot air or cooled water after heat absorption) and includes a heat-insulating shell 1 and a plurality of cooling units 2. The heat-insulating shell 1 may be, for example, a hollow cylinder, but is not limited to this, and is used to block heat transfer. The heat-insulating shell 1 defines an accommodating space 11. The cooling units 2 are disposed in the accommodating space 11 and stacked vertically. In this embodiment, two cooling units 2 are used as an example, but the number of cooling units 2 can also be one or more. The more cooling units 2 there are, the better the cooling tower device 100 can cool the fluid.

[0020] Referring to Figures 1 to 4, each cooling unit 2 includes a support frame 21, a circulation pipe 22, and multiple heat dissipation plates 23 arranged at intervals along the front-rear direction X. Each support frame 21 includes a frame body 211 and multiple L-shaped fasteners 211a. The frame body 211 is, for example, a hollow square frame with openings connecting the accommodating space 11 on all six sides (front, rear, left, right, top, and bottom), but is not limited thereto. The frame body 211 accommodates the corresponding heat dissipation plates 23. The fasteners 211a are connected in pairs to the inner surfaces of the top left and right sides and the bottom left and right sides of the frame body 211, and the multiple sets of two fasteners 211a on each side are arranged in the front-rear direction X. The two fasteners 211a in each set are spaced apart from each other and symmetrically arranged in the front-rear direction X, defining a fixing groove 211b. The fixing slots 211b are respectively for inserting the top and bottom of the heat dissipation plates 23, so that the heat dissipation plates 23 are disposed in the frame body 211.

[0021] Referring to Figures 2 to 6, the circulation pipe 22 is adapted to be connected to an outdoor unit (not shown) and is driven by the outdoor unit to circulate a refrigerant (not shown, also referred to as a coolant). The outdoor unit is equipped with components not shown, such as a compressor, evaporator, and condenser. The heat dissipation plates 23 are, for example, hollow metal plates and are connected to the circulation pipe 22. The hollow interior of each heat dissipation plate 23 forms an internal space 231 suitable for the passage of the refrigerant (see Figure 7). The outer surfaces of two adjacent heat dissipation plates 23 together define a cooling channel 24 suitable for the fluid (not shown) to pass through from top to bottom or from bottom to top.

[0022] When the refrigerant passes through the internal space 231, the heat dissipation plates 23 exchange heat with the refrigerant and form an ice layer (not shown) on the outer surface of each heat dissipation plate 23 with two adjacent cooling channels 24 on each side. This allows the heat energy of the fluid passing through the cooling channels 24 to be absorbed by the ice layer and cooled, forming a cooled fluid that is discharged outward.

[0023] Referring to Figures 7 to 9, specifically, each heat dissipation plate 23 has two plates 232 arranged front to back and jointly defining the internal space 231. Each plate 232 is, for example, a solid metal sheet, but not limited thereto, and has a plate body portion 233, for example, square, a plate periphery portion 234 connected to the periphery of the plate body portion 233, and a plurality of arrayed and recessed welding points 235 formed inwardly on the outer surface of the plate body portion 233. The plate body portions 233 of each heat dissipation plate 23 are spaced apart from each other in the front-rear direction X to form the internal space 231. The plate periphery portions 234 of each heat dissipation plate 23 are fitted together, isolating the internal space 231 from the cooling channel 24. The welding points 235 of the two plates 232 of each heat dissipation plate 23 are aligned and fitted together in pairs in the front-rear direction X. The welding points 235 of each heat dissipation plate 23 divide the internal space 231 into multiple transverse channels 231a extending in the left-right direction Y, and multiple longitudinal channels 231b extending in the up-down direction Z. The transverse channels 231a are arranged in the up-down direction Z, and the longitudinal channels 231b are arranged in the left-right direction Y. The longitudinal channels 231b connect to the transverse channels 231a, and the welding points 235 make the inner walls of the longitudinal channels 231b and the transverse channels 231a undulate like waves to increase the heat exchange area between the heat dissipation plate 23 and the refrigerant, thereby improving the cooling efficiency. In this embodiment, the welding points 235 are made by laser welding, but are not limited thereto.

[0024] Referring to Figures 4 to 6, each cooling unit 2's circulation pipe 22 has an inlet pipe assembly 221 connected to the bottom of the outdoor unit and the heat dissipation plates 23, and an outlet pipe assembly 222 connected to the top of the compressor and the heat dissipation plates 23. Each inlet pipe assembly 221 is adapted to guide the refrigerant into the bottom of the internal spaces 231, allowing the refrigerant to fill the internal spaces 231 from bottom to top. Each outlet pipe assembly 222 is adapted to guide the refrigerant that has filled the internal spaces 231 outwards. Furthermore, the inlet pipe assembly 221 and the outlet pipe assembly 222 of each cooling unit 2 are respectively connected to the left and right sides of the corresponding heat dissipation plates 23. In this way, when the refrigerant flows from the inlet pipe assembly 221 to the outlet pipe assembly 222, the refrigerant can automatically and completely fill the internal space 231 from bottom to top and from right to left, thereby increasing the heat exchange area between the heat dissipation plates 23 and the refrigerant and improving the cooling efficiency of the corresponding cooling unit 2. In this embodiment, the inlet pipe assemblies 221 of the cooling units 2 are located on the same side (right side) and connected vertically to each other, and the outlet pipe assemblies 222 of the cooling units 2 are located on the same side (left side) and connected vertically to each other, so that the heat dissipation plates 23 of the cooling units 2 can simultaneously guide the refrigerant from the inlet pipe assemblies 221 into the internal spaces 231, and simultaneously guide the refrigerant in the internal spaces 231 to the outlet pipe assemblies 222. However, in some other embodiments, the inlet pipe assemblies 221 of the cooling units 2 are located on opposite sides (left and right sides) and separated from each other, and the outlet pipe assemblies 222 of the cooling units 2 are also located on opposite sides (left and right sides) and separated from each other. The lower outlet pipe assembly 222 is connected to the upper inlet pipe assembly 221. In this way, the lower inlet pipe assembly 221 of the cooling unit 2 will first guide the refrigerant into the internal space 231 of the corresponding heat dissipation plate 23. Then, after the internal space 231 of the lower cooling unit 2 is filled, the lower outlet pipe assembly 222 guides the refrigerant to the upper inlet pipe assembly 221, so that the internal space 231 of the upper cooling unit 2 is subsequently filled.

[0025] Referring to Figures 2 to 4, preferably, each cooling unit 2 further includes two heat dissipation pipe assemblies 25 spaced apart in the front-rear direction X. The heat dissipation pipe assemblies 25 of each cooling unit 2 are located in front of and behind the corresponding heat dissipation plates 23, and connected to the front and rear sides of the corresponding support frame 21. Each heat dissipation pipe assembly 25 is connected to the circulation pipe 22 and has multiple heat dissipation pipes 251 spaced apart in the front-rear direction X and / or the left-right direction Y and extending along the vertical direction Z, a lower connecting plate 252 and an upper connecting plate 253 respectively connected to the upper and lower ends of the heat dissipation pipes 251 of the corresponding heat dissipation pipe assembly 25. Each cooling unit 2 has a lower connecting plate 252 connected to the bottom of the support frame 21 and the inlet pipe assembly 221 (only the lower connecting plate 252 of the cooling unit 2 located below is shown in Figure 2). The interior of the lower connecting plate 252 is adapted to allow the refrigerant from the inlet pipe assembly 221 to pass through the heat dissipation pipes 251. Each cooling unit 2 has an upper connecting plate 253 connected to the top of the support frame 21 and the outlet pipe assembly 222 (only the upper connecting plate 253 of the cooling unit 2 located below is shown in Figure 3). The interior of the upper connecting plate 253 is adapted to guide the refrigerant from the heat dissipation pipes 251 to the outlet pipe assembly 222. The interior of each heat dissipation pipe 251 is adapted to allow the refrigerant to pass through. The heat dissipation pipes 251 of each heat dissipation pipe assembly 25 collectively define a side cooling space 26 suitable for the passage of the fluid. When the refrigerant passes through the interior of the lower connecting plate 252, the heat dissipation pipes 251 and the upper connecting plate 253 of each cooling unit 2 in sequence, the heat dissipation pipes 251 exchange heat with the refrigerant, and another layer of ice (not shown) is formed on the outer surface of each heat dissipation pipe 251 in the corresponding side cooling space 26, so that the heat energy of the fluid passing through the side cooling space 26 is absorbed by the other layer of ice and cooled to form cooled fluid that is discharged outward.

[0026] Referring to Figures 4, 5, and 10, each support frame 21 also includes eight limiting members 212. These limiting members 212 are arranged in pairs on the front, rear, left, and right sides of the top of the corresponding frame body 211. The pairs of limiting members 212 are spaced apart from each other and adjacent to each other in adjacent groups. In other words, these limiting members 212 extend upwards from the four corners of the top of the frame body 211. When the cooling units 2 are stacked vertically, the top surface of the frame body 211 of the lower support frame 21 supports the bottom surface of the frame body 211 of the upper support frame 21. The eight limiting members 212 of the lower support frame 21 abut against the front, rear, left, and right sides of the frame body 211 of the upper support frame 21 in pairs, preventing the upper support frame 21 from moving forward, backward, left, or right, thus ensuring a stable stacking. However, in other embodiments, there may be only four limiting members 212, and the four limiting members 212 respectively abut against the front, rear, left and right sides of the frame body 211 of the upper support frame 21. In this way, the limiting members 212 can still restrict the movement of the support frame 21.

[0027] Preferably, each support frame 21 further includes four hanging members 213. The four hanging members 213 of each support frame 21 are respectively connected to the top edges of four limiting members 212 located at the four corners of the top of the frame body 211 and extend upwards. The four hanging members 213 of each support frame 21 are suitable for hooking by a crane (not shown), so that the four corners of the corresponding cooling unit 2 can be simultaneously and stably and balancedly lifted and moved by the crane. In this embodiment, the four hanging members 213 are respectively connected to pairs of limiting members 212 located on the left and right sides.

[0028] The operation of the cooling tower device 100 is described in detail below. First, the inlet pipe assembly 221 of the circulation pipes 22 introduces the refrigerant from the outdoor unit into the internal space 231 of the heat dissipation plates 23 and the interior of the heat dissipation pipe assembly 25. At this time, the heat dissipation plates 23 and the heat dissipation pipes 251 exchange heat with the refrigerant and cool down, causing water vapor in the cooling channels 24 to condense on the outer surface of the heat dissipation plates 23 to form ice layers, and water vapor in the side cooling spaces 26 to condense on the outer surface of the heat dissipation pipes 251 to form another ice layer. Furthermore, the heat insulation shell 1 is used to block the heat transfer between the ice layers and the other ice layer and the outside, thereby delaying the melting of the ice layers and the other ice layer. Next, when there is a cooling demand, one end of the containing space 11 introduces the fluid from the outside, and the cooling channels 24 and the side cooling spaces 26 allow the fluid to pass through. At this time, the ice layers located in the cooling channels 24 and the other ice layers located in the side cooling spaces 26 absorb the heat energy of the fluid and melt, so that the fluid passing through the cooling channels 24 and the side cooling spaces 26 is cooled into a cooled fluid and discharged from the other end of the containing space 11 to the outside, thereby achieving a cooling effect.

[0029] Preferably, the cooling unit 2 can be controlled to form such ice layers during off-peak electricity periods and to allow the fluid to pass through for cooling during non-off-peak electricity periods. This allows for a more even distribution of electricity throughout the day, avoiding peak electricity usage periods and thus achieving energy-saving effects.

[0030] In summary, by forming ice layers in the cooling channels 24 using the heat dissipation plates 23, the fluid passing through the cooling channels 24 can exchange heat with the ice layers and be cooled, thereby improving cooling efficiency. Furthermore, by controlling the formation of the ice layers during off-peak power periods using at least one cooling unit 2 and allowing the fluid to pass through for cooling during off-peak power periods, the cooling tower device 100 can achieve energy savings, thus effectively achieving the objectives of this invention.

[0031] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification of the present invention shall still fall within the scope of the patent of the present invention.
