Description

Technical Field

[0001] The utility model relates to the technical field of evaporative air coolers, in particular to a composite evaporative air cooler. Background Art

[0002] An evaporative air cooler is an efficient energy-saving cooling device that integrates water cooling, air cooling, heat transfer, and mass transfer processes and combines the advantages of both. It has the advantages of compact structure, high heat transfer efficiency, low investment, low operating cost, and convenient installation and maintenance. It has broad application prospects in industries such as oil refining, metallurgy, electric power, refrigeration, and light industry, and is a new direction for the development of air cooling technology.

[0003] In the process of using the existing composite evaporative air cooler, outside air enters through the air intake net below the body and then is discharged along the exhaust component at the top. During the movement of the air from the top of the body to the top, the falling cooling water is likely to combine with impurities in the air, resulting in an increase in impurities in the cooling water. These cooling waters are likely to cause a decrease in the inner diameter of the pipeline during subsequent recycling, thereby reducing the cooling efficiency. Summary of the Utility Model

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A composite evaporative air cooler includes a body. Exhaust components are symmetrically installed at the top of the body. A water collection rack is installed at the inner top of the body. A spraying component is arranged below the water collection rack. A circulation pipe is arranged below the spraying component. A recycling component is installed outside the body. A protection component is installed at the inner bottom of the body near one side of the recycling component. The protection component includes a water baffle in an L-shaped structure. A plurality of groups of through holes are evenly arranged on the vertical surface of the water baffle. A filter screen is installed at the back end of the vertical surface of the water baffle. An eccentric block is arranged outside the filter screen. A support shaft is fixed on one side inside the eccentric block, and a driving motor is installed outside the support shaft.

[0007] Preferably, the exhaust component includes an exhaust fan rotatably connected to the body, and a rotation motor is installed at the top of the exhaust fan.

[0008] Preferably, dust-proof nets are symmetrically installed on both sides below the rotation motor, and the dust-proof nets are fixed on the body.

[0011] Preferably, the inlets and outlets at both ends of the circulation pipe are both located outside the body.

[0012] Preferably, an air intake net is installed below the peripheral wall of the body, and the air intake net is snap-connected to the body.

[0013] The beneficial technical effects are as follows:

[0014] By providing a protective component, during use, the coolant can be blocked by the water baffle in the protective component, and the coolant can move to the recycling component through the through holes on the water baffle. When the coolant passes through the water baffle, the impurities inside are filtered by the filter net, preventing the inner diameter of the pipeline from decreasing during subsequent recycling use, improving the cooling efficiency. Moreover, the driving motor drives the eccentric block to rotate through the support shaft. During the rotation of the eccentric block, it contacts the filter net and causes it to vibrate, enabling the impurities adhered to the filter net to fall off, thus preventing the filter net from being blocked.

[0020] To make the technical solutions of the present invention clearer and more definite for those skilled in the art, the present invention will be further described in detail below in conjunction with the embodiments and the drawings. However, the implementation manners of the present invention are not limited thereto.

[0021] AsFigures 1 - 3 As shown in the figure, a composite evaporative air cooler provided in this embodiment includes a body 1. Exhaust components 2 are symmetrically installed at the top of the body 1. A water collection rack 3 is installed at the inner top of the body 1. The water collection rack 3 can collect the moisture in the discharged gas. A spraying component 4 is arranged below the water collection rack 3. A circulation pipe 5 is arranged below the spraying component 4. The circulation pipe 5 is used to transport the circulating liquid. A recovery component 6 is installed on the outer side of the body 1. A protection component 7 is installed on one side near the recovery component 6 at the inner bottom end of the body 1. The protection component 7 includes a water baffle 701 in an L-shaped structure. The water baffle 701 is used to block the cooling water. A plurality of groups of through holes 702 are evenly opened on the vertical surface of the water baffle 701. The cooling water moves to the recovery component 6 through the through holes 702. A filter screen 703 is installed on the back end of the vertical surface of the water baffle 701. When the water passes through the water baffle 701, the impurities inside are filtered through the filter screen 703. An eccentric block 706 is arranged outside the filter screen 703. A support shaft 705 is fixed on one side inside the eccentric block 706. A driving motor 704 is installed on the outside of the support shaft 705. The driving motor 704 drives the eccentric block 706 to rotate through the support shaft 705. During the rotation of the eccentric block 706, it contacts the filter screen 703 to cause it to vibrate, so that the impurities adhered to the filter screen 703 can fall off.

[0022] As Figures 1 - 2 shown in the figure, the exhaust component 2 includes an exhaust fan 201 rotatably connected to the body 1. A rotation motor 202 is installed at the top of the exhaust fan 201, which can drive the exhaust fan 201 to rotate by the rotation motor 202, and extract the gas through the exhaust fan 201.

[0023] As Figures 1 - 2 shown in the figure, dust-proof nets 203 are symmetrically installed on both sides below the rotation motor 202, and the dust-proof nets 203 are fixed on the body 1, which can prevent sundries from entering the body 1 from the exhaust component 2.

[0024] As Figures 1 - 2 shown in the figure, the spraying component 4 includes a pipe rack 401 fixed inside the body 1. A plurality of groups of nozzles 402 are equidistantly installed at the bottom end of the pipe rack 401, which can transport the cooling liquid through the pipe rack 401, and these cooling liquids are evenly sprayed on the circulation pipe 5 through the nozzles 402.

[0025] As Figures 1 - 2 shown in the figure, the recovery component 6 includes a pump 601 and a delivery pipe 602. The two ends of the delivery pipe 602 are respectively connected to the pump 601 and the pipe rack 401, which is convenient for the pump 601 to extract the cooling liquid, and then the cooling liquid moves into the pipe rack 401 through the delivery pipe 602.

[0026] As Figures 1 - 2 shown in the figure, the inlets and outlets at both ends of the circulation pipe 5 are located outside the body 1, which is convenient for the external pipeline to be connected to the circulation pipe 5.

[0027] AsFigures 1 - 2 As shown, air intake nets 8 are installed below the peripheral wall of the body 1, and the air intake nets 8 are snap-connected to the body 1, enabling external air to enter the body 1 through the air intake nets 8 and preventing external sundries from entering through the air intake nets 8.

[0028] Working principle of this device: When this device is in specific use, the circulation pipe 5 is connected to an external liquid inlet pipe and a liquid discharge pipe. The circulating liquid in a high-temperature state enters the circulation pipe 5 and flows. During the flowing process, external air enters the body 1 through the air intake nets 8, and the air intake nets 8 prevent external sundries from entering. At the same time, the pump 601 extracts the coolant, and then the coolant moves through the delivery pipe 602 to the pipe rack 401 on the spraying assembly 4. These coolants are evenly sprayed on the circulation pipe 5 through the nozzles 402, thereby cooling the circulating liquid in the circulation pipe 5. The rotating motor 202 can drive the exhaust fan 201 to rotate. The exhaust fan 201 extracts the moist gas generated after the coolant contacts the circulation pipe 5 and discharges it. The water collecting rack 3 can collect the water in the discharged gas, and the excess coolant falls to the bottom end inside the body 1 by gravity. At the same time, the baffle 701 in the protection assembly 7 blocks the coolant, and these coolants can move to the recovery assembly 6 through the through holes 702 on the baffle 701. When the coolant passes through the baffle 701, the impurities inside it are filtered through the filter screen 703 to avoid reducing the inner diameter of the pipeline during subsequent recycling, improving the cooling efficiency. And the driving motor 704 drives the eccentric block 706 to rotate through the support shaft 705. During the rotation of the eccentric block 706, it contacts the filter screen 703 and causes it to vibrate, enabling the impurities adhered to the filter screen 703 to fall off, thus avoiding blocking the filter screen 703.

[0029] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent replacements or changes, all belong to the protection scope of the present utility model.
