Description

Technical Field

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

[0002] An indirect evaporative cooler is a device that utilizes heat and moisture exchange between unsaturated air and water and uses natural cold sources to obtain cold air and cold water. The structure of a vertical tube indirect evaporative cooler is as follows: the inside of the heat exchange tube is water film and secondary air, and the outside of the tube is primary air. The flow path of the primary air is shorter than that of other forms of heat exchangers, and the resistance loss is small, so it occupies a small area and is used in many cluster air-conditioning and refrigeration equipment.

[0003] After searching, a vertical indirect evaporative cooler with announcement number CN216845772U includes a box body, wherein the box body has a horizontally arranged upper tube sheet and a lower tube sheet, and the upper tube sheet and the lower tube sheet are fixedly sealed around the inner wall of the box body, and vertically arranged heat exchange tubes are evenly distributed between the upper tube sheet and the lower tube sheet, and the upper end of the heat exchange tube passes through the upper tube sheet, and the lower end of the heat exchange tube passes through the lower tube sheet. A primary air inlet and a primary air outlet are provided on a set of parallel side walls of the section of the box body between the upper tube sheet and the lower tube sheet. A secondary air inlet is provided on the side wall of the box body below the lower tube sheet, and a secondary air outlet is provided on the top of the box body. A spray pipe is provided in the box body above the upper tube sheet, and a circulation pipe is provided between the spray pipe and the bottom of the box body, and a circulation pump is provided on the circulation pipe. It is characterized in that grooves are evenly distributed on the inner wall of the heat exchange tube along its circumference, so that the inner wall of the heat exchange tube is rough. The cooler has high heat exchange efficiency, small size, and low energy consumption;

[0004] Based on the above patent, the inner wall of the heat exchange tube is evenly distributed with grooves along its circumference, so that the inner wall of the heat exchange tube is rough. The grooves on the inner wall of the heat exchange tube have a capillary effect, which strengthens the expansion of the water film on the heat exchange surface, is conducive to controlling the uniform thickness of the water film formed on the heat exchange surface, reducing the temperature difference in the internal area of ​​the heat exchanger, and the heat exchange efficiency is high. Moreover, the rough inner wall of the heat exchange tube can make the water film formed on the inner surface of the heat exchange tube evenly coated, avoid the dry area on the heat exchange surface, and improve the heat exchange efficiency of the heat exchanger. In addition, the rough inner wall of the heat exchange tube can also increase the Reynolds number of the secondary air flowing through the heat exchange tube, improve the flow state of the secondary air, and further improve the efficiency of heat exchange. Therefore, the heat exchange efficiency of this vertical indirect evaporative cooler can achieve the required heat exchange with fewer heat exchange tubes, reducing the size of the heat exchanger. At the same time, by increasing the Reynolds number of the secondary air, a smaller secondary air volume can also achieve the required heat exchange, greatly reducing energy consumption. However, the above device lacks the ability to filter dust in the primary air. After long-term use, the surface of the heat exchange tube is easily adhered to dust, which affects the heat exchange effect and reduces the cooling efficiency.

[0005] In view of this, and aiming at this technical problem, the present application proposes a vertical indirect evaporative cooler. Utility Model Content

[0027] The humid air (secondary air) obtained by evaporative cooling is introduced into the device through the secondary air inlet pipe 26, and the fan 19 is started to drive the secondary air to be discharged through the heat exchange pipe 17, the water baffle 25 and the secondary air outlet pipe 18. The water baffle 25 can block the water vapor in the secondary air and make the water vapor fall into the bottom of the device. By starting the water pump 22, the water and water vapor sprayed from the spray pipe 24 are transported to the spray pipe 24 through the first circulation pipe 21 and the second circulation pipe 23, and sprayed again. The primary air enters the device through the primary air inlet pipe 2 and is filtered by the filter 10. The dust in the air is filtered to prevent the surface of the heat exchange tube 17 from being stuck by dust and affecting the heat exchange effect. Then, by starting the motor 3, the primary air inlet pipe 2 is driven to rotate, and then the first connecting rod 4 is driven to rotate. Through the transmission relationship between the active bevel gear 5 and the driven bevel gear 6, the second connecting rod 7 is driven to rotate, and then the cleaning plate 8 is driven to rotate to clean the filter 10 to prevent dust from clogging the filter 10.

The water baffle 25 can block the water vapor in the secondary air and make the water vapor fall into the bottom of the device. By starting the water pump 22, the water and water vapor sprayed from the spray pipe 24 are transported to the spray pipe 24 through the first circulation pipe 21 and the second circulation pipe 23, and sprayed again. The primary air enters the device through the primary air inlet pipe 2, and the dust in the primary air is filtered by the filter 10, which can prevent the surface of the heat exchange tube 17 from being adhered to by dust and affecting the heat exchange efficiency. The result is that the motor 3 is started, thereby driving the primary air inlet pipe 2 to rotate, and then driving the first connecting rod 4 to rotate. Through the transmission relationship between the active bevel gear 5 and the driven bevel gear 6, the second connecting rod 7 is driven to rotate, and then the cleaning plate 8 is driven to rotate, so as to clean the filter 10 to prevent dust from clogging the filter 10. The primary air after filtering the dust exchanges heat with the secondary air in the heat exchange tube 17 through the outside of the heat exchange tube 17, so as to achieve the process of cooling the primary air and discharge it through the primary air outlet pipe 20. The cleaned dust is collected into the collection box 13 through the connecting pipe 11, and then the handle 14 is pulled to drive the collection box 13 to move to the left, so as to facilitate the cleaning process of the collection box 13 after collection.
