Description

Technical Field

[0001] This utility model belongs to the field of air cooler technology, specifically relating to a packing composite high-efficiency evaporative air cooler. Background Technology

[0002] Air coolers, as an important heat exchange device, are widely used in chemical, power, metallurgical and other industrial fields. Their core function is to achieve heat exchange by cooling the circulating medium (such as water, steam, etc.) with air. In order to enhance the cooling effect of air coolers, some devices have begun to use cooling packing to enhance the heat and mass transfer process on the air side. The heat exchange efficiency is significantly improved by the evaporative cooling effect of the packing. For example, the existing patent with publication number CN202709804U discloses "a composite evaporative air cooler, including a water tank at the bottom, a shell above the water tank, an air inlet on the shell, a heat exchange device inside the shell and above the air inlet, a spray device above the heat exchange device, a circulating water pump connected to the spray device through a spray water pipe, a water collector above the spray device, and a cooling device above the water collector". It can be seen that the application describes a common composite evaporative air cooler.

[0003] However, in the actual use of such composite evaporative air coolers, the internal cooling packing is mostly welded, bolted, or integrally nested, which makes it difficult to disassemble and maintain the cooling packing in the later stage, increasing the maintenance cost of the air cooler for the operators and making it impossible to quickly disassemble and maintain the cooling packing. Therefore, this utility model proposes a high-efficiency evaporative air cooler with composite packing. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 4This is the first embodiment of the present invention, which provides a technical solution: a packed composite high-efficiency evaporative air cooler, comprising a water tank 4 at the bottom of the air cooler body 1, a heat exchange plate bundle 2 installed at the center of the air cooler body 1, an air inlet 3 disposed on the front surface of the air cooler body 1, a cooling fan 7 installed on the top of the air cooler body 1, and a circulating water pump 6 installed on the right side of the water tank 4. The circulating water pump 6 is connected to a spray pipe at the top inner side of the air cooler body 1 through a pipeline to spray the inner surface of the heat exchange plate bundle 2. The heat exchange plate bundle 2 has a medium inlet 11 and a medium outlet 12 respectively disposed on both sides of its surface. For the entry and exit of the heat medium, after the heat medium enters the heat exchange plate bundle 2, it can be sprayed by the spray pipe at the top of the inner side of the air cooler body 1 to achieve evaporative cooling. Before the sprayed water falls onto the surface of the heat exchange plate bundle 2, it is first cooled by the cooling filler 52, which removes some of the heat in the water. Then it falls onto the heat exchange plate bundle 2 for evaporative cooling, thereby removing more heat from the heat exchange plate bundle 2 and achieving cooling of the medium. The above structure is a technology that has been disclosed in the prior art. For the specific structural principle, please refer to the existing patent with publication number CN202709804U. It will not be elaborated on here.

[0024] The drawer-type packing assembly located above the heat exchange plate bundle 2 includes an outer end plate 5, a drawer frame 51 welded and fixed to the back of the outer end plate 5, and cooling packing 52 installed in the drawer frame 51. The outer end plate 5 is attached to the front surface of the air cooler body 1, and the drawer frame 51 extends through to the inside of the air cooler body 1 and is located at the top of the heat exchange plate bundle 2. The drawer-type installation method allows subsequent operators to quickly pull out the drawer frame 51 to replace or clean the cooling packing 52 without disassembling the outer shell of the air cooler body 1.

[0025] The quick-release limiting structure 8 is provided between the outer end plate 5 and the air cooler body 1. It includes two U-shaped base blocks 81 welded and fixed to the top surface of the outer end plate 5, two cylindrical base blocks 82 corresponding to the U-shaped base blocks 81 welded and fixed to the front surface of the air cooler body 1, and a rotating pressure strip 83 movably installed at the front end of the cylindrical base blocks 82. The end of the rotating pressure strip 83 presses against the surface of the U-shaped base blocks 81, which can effectively press and limit the U-shaped base blocks 81 to ensure the pressing stability of the outer end plate 5, thereby ensuring the installation stability of the drawer-type packing assembly.

[0026] In this embodiment, preferably, a rectangular slot for inserting the drawer frame 51 is provided through the front surface of the air cooler body 1.

[0027] In this embodiment, preferably, a cylindrical inner groove 86 is formed inside the cylindrical base block 82. A cylindrical inner sliding plate 87 and a spring 88 are installed inside the cylindrical inner groove 86. A cylindrical connecting rod 89 is fixed to the front surface of the cylindrical inner sliding plate 87, and the front end of the cylindrical connecting rod 89 extends through to the front surface of the cylindrical base block 82 and is fixed to the rotating pressure strip 83. Under the pushing of the spring 88, the rotating pressure strip 83 can be stably pressed against the front surface of the U-shaped base block 81 during daily use. One end of the spring 88 abuts against the inner wall of the cylindrical inner groove 86, and the other end of the spring 88 abuts against the front surface of the cylindrical inner sliding plate 87. The quick-release structure 8 also includes two limiting blocks 84 welded and fixed to the front surface of the U-shaped base block 81. A corresponding limiting block 84 is formed through the surface of the rotating pressure strip 83. The limiting hole 85 has a limiting block 84 that engages with it, allowing the rotating pressure strip 83 to be stably pressed against the front surface of the U-shaped base 81 during daily use, preventing it from rotating and moving away on its own. To quickly release the limiting effect on the outer end plate 5, simply pull the rotating pressure strip 83 forward, causing the cylindrical connecting rod 89 to move forward along with the cylindrical inner slide plate 87, gradually compressing the spring 88 until the limiting block 84 is no longer in the limiting hole 85. Then, rotate the rotating pressure strip 83 90 degrees so that it aligns with the opening of the U-shaped base 81, thus no longer obstructing the U-shaped base 81. At this point, the outer end plate 5 can be moved forward, allowing the drawer frame 51 and cooling filler 52 to be easily removed from the air cooler body 1 for replacement or cleaning.

[0028] In this embodiment, preferably, a guide support strip 13 is fixed on each of the inner walls on both sides of the air cooler body 1 above the heat exchange plate bundle 2, and the guide support strip 13 slides in contact with the side of the drawer frame 51, so as to play a guiding and supporting role during the drawer frame 51 being pulled out.

[0029] Example 2

[0030] Please see Figures 1 to 4This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the guide support bar 13 has a groove 131 on its side, and a rubber seat 132 is embedded in the groove 131. The side of the rubber seat 132 has an integrated positioning protrusion 133. Both are made of fluororubber and will undergo elastic deformation when squeezed. The two sides of the drawer frame 51 have positioning slots 511 corresponding to the positioning protrusions 133. The positioning protrusions 133 are inserted into the positioning slots 511, so that after the drawer frame 51 is pushed into the air cooler body 1 by the operator, it can slide between the two guide support bars 13. When the outer end plate 5 is attached to the front surface of the air cooler body 1, the drawer frame 51 is pushed into place, and at this time the positioning protrusions 133 will be inserted into the positioning slots 511, realizing the auxiliary limit of the drawer frame 51 at this time, thereby facilitating the subsequent further limit of the outer end plate 5 by the operator.

[0031] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
