Description

Technical Field

[0001] The invention discloses a device, which relates to the technical field of data center cooling, in particular to an indirect evaporative cooling data center air conditioning device. Background Art

[0002] A data center is a global collaborative network of specific equipment used to transmit, accelerate, display, calculate, and store data information on the Internet infrastructure. Most electronic components in a data center are driven by low DC power supplies.

[0003] Data centers are usually places where telecommunications, Netcom, mobile, dual-line, power, government or enterprise servers are stored. At the same time, data centers are equipped with air-conditioning devices to cool data servers. Existing air-conditioning devices usually use traditional refrigeration and indirect evaporative refrigeration technology to cool data centers. Air-conditioning devices using indirect evaporative refrigeration technology transfer the cold in the outdoor fresh air to the indoor return air through the intersection of indoor return air and outdoor fresh air, and pre-cool the indoor return air. However, the intersection time of indoor return air and outdoor fresh air is usually short, which will prevent the indoor return air from obtaining more cold air from the outdoor return air. At the same time, when the indoor return air is subjected to spray cooling treatment, the indoor return air is continuously transported at a faster rate, so that the indoor return air cannot fully contact with the spray water, thereby reducing the cooling efficiency of the indoor return air, resulting in a reduced pre-cooling effect of the indoor return air, and thus resulting in the overall energy consumption cannot be effectively reduced.

[0055] The present invention includes a shell 1, a fan unit 2, a refrigerator 3, a heat exchange box 4, a cooling mechanism 5, a dividing mechanism 6, a purification mechanism 7, a first air guide hole plate 15 and a second air guide hole plate 16 and a sprayer 8.

[0056] Further, based on the technical solution of the present invention, in some embodiments of the present invention, the cooling mechanism 5 includes a fixed box 501, a fixed plate 502, a guide plate 503, a sponge 504 and a connecting pipe 505, the fixed box 501 is fixedly connected to the inside of the heat exchange box 4, the side of the fixed plate 502 close to the inner wall of the fixed box 501 is fixedly connected to the fixed box 501, the side of the guide plate 503 close to the fixed plate 502 is fixedly connected to the fixed plate 502, the sponge 504 is fixedly connected to the inside of the guide plate 503, the side of the connecting pipe 505 close to the guide plate 503 is fixedly connected to the guide plate 503, and the side of the connecting pipe 505 close to the diverting mechanism 6 is fixedly connected to the diverting mechanism 6.

[0057] Further, based on the technical solution of the present invention, in some embodiments of the present invention, the direction-dividing mechanism 6 includes a fixed plate 601, a fixed rod 602, a bearing 603, a movable plate 604, a first through hole 605, a second through hole 606 and a push plate 607, the fixed rod 602 is fixedly connected to the fixed box 501 on one side close to the fixed box 501, the surface of the fixed rod 602 is fixedly connected to the inner wall of the fixed plate 601, the surface of the bearing 603 is fixedly connected to the inner wall of the movable plate 604, the inner wall of the bearing 603 is fixedly connected to the surface of the fixed rod 602, the first through hole 605 is opened inside the fixed plate 601, the second through hole 606 is opened inside the movable plate 604, and the push plate 607 is close to one side of the movable plate 604.

The larger impurities or foreign objects carried in the indoor return air and the outdoor fresh air can be filtered through the primary filter plate 707, and the smaller impurities in the indoor return air and the outdoor fresh air are intercepted again through the secondary filter plate 708. Finally, the particulate impurities in the indoor return air and the outdoor fresh air are adsorbed by the activated carbon filter plate 709, so that the indoor return air and the outdoor fresh air can be kept clean, avoiding the carrying of impurities for subsequent treatment, thereby ensuring the purity of the cooling air and will not affect the facilities in the data center.

[0059] Further, based on the technical solution of the present invention, in some embodiments of the present invention, the number of fixed plates 502 is two, and they are fixedly connected to the front and rear sides of the fixed box 501; the number of guide plates 503 is several, and they are fixedly connected between the two fixed plates 502 at equal intervals; a fluid channel is formed between two adjacent guide plates 503; by setting the number of fixed plates 502 to two, it is possible to facilitate the installation of multiple guide plates 503 to the use position, so that a seal is formed between the guide plates 503 and the fixed plates 502, thereby achieving the effect of limiting the flow trajectory of indoor return air; by increasing the number of guide plates 503 to several, and fixing them between the two fixed plates 502 at equal intervals, it is possible to facilitate the formation of a fluid channel between the two adjacent guide plates 503, thereby facilitating the indoor return air to flow between the two guide plates 503, and allowing the indoor return air to fully contact with the spray water.

[0060] Furthermore, based on the technical solution of the present invention, in some embodiments of the present invention, a closing plate 9 is fixedly connected to the opposite side of the upper and lower guide plates 503, and the connecting pipe 505 is fixedly connected to the guide plate 503 through the closing plate 9. The number of connecting pipes 505 is four, and they are respectively fixedly connected to the closing plate 9. The guide plate 503 is wavy in shape and stacked between the two fixed plates 502. By setting the closing plate 9, the effect of sealing the two guide plates 503 can be achieved to prevent the indoor return air from being discharged from between the two guide plates 503. By setting the number of connecting pipes 505 to four and fixing them to the closing plate 9 respectively, it is convenient to cooperate with the diversion mechanism 6 to divide the indoor return air into multiple strands, which can accelerate the cooling rate of the indoor return air. By stacking the guide plates 503 between the two fixed plates 502 in a wavy shape, the indoor return air can enter between the two guide plates 503 without the occurrence of flow dead corners, thereby ensuring the normal flow of the indoor return air.

By setting the liquid outlet hole 10, the spray water can be easily discharged from the fixed box 501 and the circulating spraying work can be carried out after treatment. By setting the air guide cover 11, the indoor return air can be easily guided to the refrigerator 3, so that the refrigerator 3 can compensate the cooling capacity of the indoor return air.

[0062] Further, based on the technical solution of the present invention, in some embodiments of the present invention, the number of the first through holes 605 is four, and they are respectively opened inside the fixed disk 601 corresponding to the connecting pipes 505, the number of the pushing plates 607 is several, and they are evenly fixedly connected to the movable disk 604, and the pushing plates 607 are arranged on the movable disk 604 in an inclined state. By setting the number of the first through holes 605 to four, and opening them inside the fixed disk 601 corresponding to the connecting pipes 505, respectively, it is convenient to guide the indoor return air to between the two guide plates 503, and by setting the number of the pushing plates 607 to several, and installing them on the movable disk 604 in an inclined state, the windward surface of the pushing plates 607 can be consistent with the flow direction of the indoor return air, so that the indoor return air can easily push the movable disk 604 to rotate, thereby performing directional work on the indoor return air.

[0063] Further, based on the technical solution of the present invention, in some embodiments of the present invention, a support frame 12 is provided on the surface of the frame 705, and the support frame 12 is fixedly connected to the box body 701 on one side close to the inner wall of the box body 701.

The top and bottom of the right side of the box body 701 are respectively fixedly connected with a return air duct 13 and a fresh air duct 14. By setting the support frame 12, the effect of supporting the frame 705 can be achieved when the frame 705 is installed, so that the frame 705 can be stably installed inside the box body 701. By setting the return air duct 13 and the fresh air duct 14, it is convenient to suck indoor return air and outdoor fresh air into the shell 1 for processing.

[0064] Further, based on the technical solution of the present invention, in some embodiments of the present invention, the bottom of the shell 1 is fixedly connected to an air outlet 17. Since the top of the heat exchange box 4 is fixedly connected to the first air guide hole plate 15, and the bottom of the heat exchange box 4 is fixedly connected to the second air guide hole plate 16, by arranging the first air guide hole plate 15 and the second air guide hole plate 16, the effect of guiding the indoor return air and the outdoor fresh air respectively can be achieved. At the same time, the hole-shaped arrangement can slow down the convergence rate of the indoor return air and the outdoor fresh air, increase the convergence time of the indoor return air and the outdoor fresh air, and enable the indoor return air to obtain more cooling from the outdoor fresh air. By arranging the air outlet 17, the processed indoor return air can be discharged into the data center for cooling.

[0065] It should be noted that the present invention is an indirect evaporative cooling data center air conditioning device. First, the fan 704 works to suck the indoor return air and the outdoor fresh air into the box body 701 through the return air duct 13 and the fresh air duct 14 respectively. Then, the larger impurities or foreign objects carried in the indoor return air and the outdoor fresh air can be filtered through the primary filter plate 707. The smaller impurities in the indoor return air and the outdoor fresh air are intercepted again through the secondary filter plate 708. Finally, the particulate impurities in the indoor return air and the outdoor fresh air are adsorbed by the activated carbon filter plate 709. The purified indoor return air and the outdoor fresh air enter the heat exchange box 4 for heat exchange. At the same time, the sprayer 8 works and the sprayer 8 sprays the sponge 504 and the outdoor fresh air respectively. The outdoor fresh air after spraying intersects with the indoor return air through the second air guide hole plate 16. The outdoor fresh air after intersection is discharged from the shell body 1 by the top fan unit 2 through the first air guide hole plate 15, and the indoor return air contacts the push plate 607 through the first air guide hole plate 15. And push the push plate 607 to rotate, so that the push plate 607 drives the movable disk 604 to drive the bearing 603 to rotate on the surface of the fixed rod 602. When the movable disk 604 drives the second through hole 606 to coincide with the first through hole 605 on the fixed disk 601, a part of the indoor return air can be introduced into a group of guide plates 503. By setting the first through holes 605 at different positions, the indoor return air can be introduced into different positions and enter between the two guide plates 503 through the connecting pipe 505. Under the action of the sprinkler 8, the spray water is sprayed on the sponge 504. The sponge 504 absorbs a part of the spray water, and a part of the spray water contacts with the indoor return air. Multiple streams of indoor return air pass through the sponge 504 and are discharged from the fixed box 501 from top to bottom to complete the cooling process. Then, they are transported to the refrigerator 3 by the air guide cover 11 for cooling compensation. Finally, the indoor return air after cooling is sent through the air outlet 17 through the fan unit 2 at the bottom into the data center for cooling.

[0066] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
