The water after heat exchange falls into the water collection assembly 103 and is discharged through the drain valve 111. The upper shell 101 and the lower shell 102 are connected and fixed by bolts.

[0025] The sliding frame 104 is detachably connected to the lower housing 102 and slides within the lower housing 102, located below the inner shell inside the upper housing 101. The lower partition 105 is detachably connected to the sliding frame 104 and located at the bottom of the sliding frame 104. A first filler layer 115 is provided on the upper side of the lower partition 105. The upper partition 106 is detachably connected to the sliding frame 104 and located above the first filler layer 115. A second filler layer 116 is provided on the upper partition 106. The movable door 107 is detachably connected to the lower housing 102 and is located on the side of the lower housing 102 near the sliding frame 104. The abutment plate 108 is integrally formed with the movable door 107 and abuts against the sliding frame 104. The sealing gasket 109 is detachably connected to the movable door 107 and is fitted onto the outside of the abutment plate 108. The handle 110 is welded to the movable door 107. The lower housing 102 is provided with a mating cavity for mounting the sliding frame 104. The mating cavity is in the form of one side being through and the other side being closed. The lower partition 105 is fixed to the bottom of the stepped interior of the sliding frame 104 by four fixing bolts, and multiple water passage grooves are provided at the bottom. The lower partition 105 is provided with the first packing layer 115.

The upper partition 106 is provided with multiple water passage grooves at the bottom and the second packing layer 116 is provided on the upper side. The abutment plate 108 is integrally provided on the movable door 107 and is used to abut against the sliding frame 104 for limiting the position after the movable door 107 is installed. An installation groove is provided at the connection between the abutment plate 108 and the movable door 107 to facilitate the installation of the sealing gasket 109. The function of the sealing gasket 109 is to improve the sealing performance after the movable door 107 is installed. The handle 110 facilitates the installation and removal of the movable door 107.

[0026] Secondly, a drain valve 111 is provided at the bottom of the water collection assembly 103. The drain valve 111 is used to discharge the water after heat exchange.

[0028] Finally, the stabilizing bracket 114 is welded and fixed to the left bracket 112 and the right bracket 113 respectively, and is set at a certain angle. After the stabilizing bracket 114 is set, it will improve the stability of the ends of the left bracket 112 and the right bracket 113 near the lower housing 102.

[0029] When using this utility model to solve the problem of inconvenience caused by the need to disassemble the water collection assembly before replacing the packing in existing open cooling towers, the cooling tower body 100, during operation, delivers hot water through an L-shaped inlet pipe on one side of the upper shell 101 to the inner shell. The inner shell, driven by a waterproof motor and shaft, rotates, generating centrifugal force that evenly throws the hot water from the bottom water outlet onto the first packing layer 115 and the second packing layer 116 to complete heat exchange. This increases the utilization rate of the packing and improves cooling efficiency. The water after heat exchange falls into the water collection assembly 103 and is discharged through the drain valve 111. When the first packing layer 115 and the second packing layer 116 need to be replaced... During replacement, simply remove the fixing bolts of the movable door 107, then remove the movable door 107 using the handle 110. Finally, pull the sliding frame 104 outward to remove the first packing layer 115 and the second packing layer 116 from the equipment together. After removal, the second packing layer 116 can be replaced first. Then, after removing the fixing bolts of the upper partition 106, the upper partition 106 can be removed to replace the first packing layer 115. In this application, the water collection component 103 can be replaced without disassembly during packing replacement, thus solving the problem that existing open cooling towers require disassembly of the water collection component for packing replacement, causing inconvenience.
