In the field of cooling computing equipment by adopting a traditional cooling tower, the cooling tower sprays water for a heat exchanger by using circulating water inside the cooling tower, cools the heat exchanger by using evaporation and heat absorption of water, and then drives airflow in the cooling tower to circulate by a fan positioned at the top of the cooling tower so as to take hot airflow subjected to heat exchange with the heat exchanger out of the cooling tower, so that the purpose of cooling is achieved. When the external environment temperature is lower, the cooling tower can also close the water cooling system, the air cooling mode is independently adopted for cooling the computing equipment, and the working mode is a dry working condition running mode.

However, impurities from the external environment easily enter the inside of the cooling tower and are deposited in the water collecting tray at the bottom of the cooling tower, and when the wet condition operation mode is started, the impurities flow along with the internal water circulation and are attached to positions such as the inside of a water circulation pipeline, the inside of an internal spray header, the surface of a heat exchanger and the like. Impurities attached to the surface of the heat exchanger can reduce the heat exchange efficiency between the heat exchanger and the outside, so that the cooling capacity of the cooling tower is reduced; in addition, the internal spray header is easily blocked by impurities, and once the spray header is blocked, the cooling tower cannot continue to work. When the internal spray header is maintained or the water collecting tray in the cooling tower is cleaned, the operation of the cooling equipment needs to be suspended, so that the utilization rate of the cooling equipment is influenced, and the operation and maintenance work is inconvenient.

In order to solve the technical problem, the utility model provides a portable dismouting spray cooling device, this portable dismouting spray cooling device includes portable regulation support, through portable regulation support, portable dismouting spray cooling device detachably installs in preset position, for example detachably installs in preset position relative to the cooling tower, not only can be in the lower period of cooling demand (for example spring and autumn) alone for the heat exchanger cooling and not start the inside shower head of cooling tower, reduce the operating time of the wet operating mode of cooling tower, reduce the frequency of use of inside shower head, thereby reduce the jam of inside shower head and pipeline; and can also assist the cooling of inside shower head in the period that the cooling demand is higher (for example summer), improve the cooling capacity of cooling tower. In addition, when the portable detachable spray cooling device is not needed for cooling (for example, in winter), the portable detachable spray cooling device can be conveniently detached, so that the maintenance is convenient, and the normal operation of the cooling tower cannot be interrupted.

The portable detachable spray cooling device according to the embodiment of the present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram illustrating a portable disassembled spray cooling device according to an exemplary embodiment of the present invention. As shown in fig. 1, the portable detachable spray cooling device 100 includes: an air flow generating unit 110 including an air flow outlet; a spray unit 120 disposed at an air flow outlet side of the air flow generation unit 110, and including an air flow input end facing the air flow outlet of the air flow generation unit 110, a spray output end, and a spray unit water inlet; a water supply unit 130 including a water supply unit inlet and a water supply unit outlet, the water supply unit outlet communicating with the spray unit inlet to supply water to the spray unit 120; and a portable adjustable stand 140 comprising a securing mechanism for securing at least one of the airflow generating unit 110 and the spray unit 120 to the portable adjustable stand 140, and by which portable adjustable stand 140 the portable detachable spray cooling device 100 is detachably mounted in a predetermined position, for example, a predetermined position relative to a cooling tower. The hollow arrows in fig. 1 indicate the general direction of flow of the air flow. Thus, the supplied water from the water supply unit 130 enters the spraying unit 120 through the spraying unit water inlet, and is atomized into a mist by the spraying unit 120. The airflow generated by airflow generating unit 110 ejects water mist from the mist output end of mist spraying unit 120 via the airflow input end of mist spraying unit 120, and can generate water mist droplets that can be substantially completely vaporized at the heat exchanger inside the cooling tower. In addition, the portable detachable spray cooling device 100 fixed on the portable adjusting bracket 140 can be detachably installed at a predetermined position along with the portable adjusting bracket 140, and can be detached according to requirements, thereby facilitating use and maintenance.

According to some embodiments, the airflow generating unit 110 may include a fan, which may be an axial flow fan that may generate a relatively high flow rate of airflow and have a relatively simple structure for easy maintenance. On one hand, the fan can spray the water mist generated by the spraying unit into a heat exchanger in the cooling tower, so that the water mist is quickly vaporized and absorbs heat at the heat exchanger; on the other hand, the air quantity entering the cooling tower can be increased, the pressure of an air outlet fan at the upper part of the cooling tower can be relieved, and the energy-saving effect is achieved on fan loads. In addition, the airflow generating unit may also include other types of fans or exhaust fans, etc., which are not described in detail herein.

According to some embodiments, the spraying unit 120 may be fixedly connected with the air flow generating unit 110. The positions of the spraying unit 120 and the airflow generating unit 110 are relatively fixed, and after the positions of the spraying unit 120 and the airflow generating unit 110 are adjusted to a proper installation distance, the airflow generated by the airflow generating unit 110 is blown to the spraying unit 120 as much as possible, so that the utilization efficiency of water and the atomization efficiency of the spraying unit 120 are improved, and further, the target to be cooled (such as a heat exchanger inside a cooling tower) is cooled to the maximum extent. The fixing connection may be a screw connection, a welding connection, an adhesive connection, a snap connection, or a detachable or non-detachable connection via a special connector, which is not limited herein.

According to some embodiments, the portable detachable spray cooling device 100 may include a water collection tank 150, and the water collection tank 150 may be disposed at a lower side of the portable detachable spray cooling device 100 and receive water from above the water collection tank 150, which may prevent water mist or water leakage generated by the portable detachable spray cooling device 100 from dripping to the ground or other equipment below, causing unnecessary loss or pollution. The water collection sump 150 may have any shape suitable for mounting on the underside of the portable detachable spray cooling device 100 and may be connected in any manner of connection, not limited thereto.

The technical solution of the present invention will be described below with reference to the accompanying drawings, how to cool by combining the portable detachable spray cooling device with a cooling tower.

Fig. 2 is a schematic diagram illustrating a cooling tower with a portable disassembled spray cooling device according to an exemplary embodiment of the present invention. As shown in fig. 2, portable disassembled spray cooling device 100 according to an exemplary embodiment of the present invention can be detachably installed outside of the side wall 210 of the cooling tower 200, and the horizontal position of the portable disassembled spray cooling device 100 is lower than the horizontal position of the heat exchanger 250 inside the cooling tower, and the portable disassembled spray cooling device 100 sprays toward the heat exchanger 250.

As shown in fig. 2, the cooling tower 200 includes a sidewall 210, a blower 220, an internal shower head 230, a circulation pipe 240, a heat exchanger 250, a water collection tray 260, and an air intake 270. The hollow arrows in fig. 2 indicate the general direction of flow of the air flow. Under the condition that the portable detachable spray cooling device 100 is not installed, the cooling tower sprays water for the heat exchanger 250 by using circulating water inside the cooling tower, a part of the sprayed water drops is vaporized and absorbs heat at the heat exchanger 250, the fan 220 positioned at the top of the cooling tower 200 drives airflow in the tower to circulate, and hot airflow after heat exchange with the heat exchanger is taken out of the cooling tower 200; another portion of the sprayed water droplets drop into a water collection tray 260 located at the bottom of the cooling tower 200, and the stored water in the water collection tray 260 is recirculated through the circulation line 240 to spray the heat exchanger 250 through the internal spray header 230. In some cases, foreign substances (e.g., dust, poplar seed, etc.) from the external environment may enter the inside of the cooling tower 200 through the air inlet 270, and the water circulating inside for a long time may also generate foreign substances such as scale. After the continuous wet working condition operation in spring, summer and autumn, partial impurities in water easily block the inner spray header 230, so that equipment is shut down; or attached to the surface of the heat exchanger 250, which reduces the heat exchange efficiency and causes inconvenience to the use and maintenance of the cooling tower equipment.

According to some embodiments, as shown in FIG. 2, the portable disassembled spray cooler 100 can be installed at the air inlet 270 of the side wall 210 (the left air inlet in FIG. 2) by using the existing air inlet 270 of the cooling tower 200, without additionally providing a new opening on the side wall 210. The portable detachable spray cooling device 100 sprays water to the radiator 250 from the lower part of the heat exchanger 250, and the sprayed water is quickly vaporized at the radiator 250 to take away a large amount of heat; moreover, because the liquid drops after water atomization are small, the water can be vaporized basically and cannot be dripped to a water collecting tray below like the traditional internal spraying mode, so that the utilization rate of the water is low. In a time period with low cooling requirements (such as spring and autumn), the portable detachable spray cooling device 100 can independently cool the heat exchanger 250 without starting the spray header 230 in the cooling tower, so that the running time of the wet working condition of the cooling tower is reduced, the use frequency of the spray header 230 is reduced, and the blockage of the spray header 230 and the circulation pipeline 240 is reduced; in a period of time (e.g., summer) when the cooling demand is high, the portable detachable spray cooling device 100 can also assist the inner spray header 230 in cooling, thereby improving the cooling capacity of the cooling tower. In addition, when the working condition is dry (for example, winter), the portable detachable spray cooling device 100 can be conveniently detached, so that the maintenance is convenient, and the normal operation of the cooling tower 200 cannot be interrupted.

Fig. 3 is a schematic structural diagram illustrating an indirect evaporative cooling apparatus equipped with a portable disassembled spray cooling device according to an exemplary embodiment of the present invention. Wherein the hollow arrows indicate the general direction of flow of the air flow. As shown in FIG. 3, a portable disassembled spray cooler 100 according to an exemplary embodiment of the present invention can also be mounted on an indirect evaporative cooling apparatus 300. The indirect evaporative cooling equipment 300 transfers the cold energy of the wet air (secondary air) obtained by direct evaporative cooling to the air to be treated (primary air) through the indirect contact heat exchanger 350 to realize air equal-humidity cooling. The portable detachable spray cooling device 100 can cool the heat exchanger 350 by the same principle as that shown in fig. 2, and will not be described herein.

According to some embodiments, the water supply unit inlet of the portable detachable spray cooling device 100 may be in communication with a municipal water supply. The relatively clean municipal water supply is adopted, so that the problems of blockage of an internal spray header and the like caused by internal water circulation can be fundamentally avoided; on the other hand, municipal water supply's temperature is generally lower, and the low temperature water smoke that forms by low temperature municipal water supply is bigger with the heat exchanger difference in temperature, can improve heat exchange efficiency. Here, the municipal water supply may be communicated with the water supply unit inlet through various types of valves, connectors, and may be controlled by input of water supply through the valves.

The following will continue to describe other configurations of the portable detachable spray cooling device with reference to fig. 4. Fig. 4 is a schematic structural diagram illustrating a portable disassembled spray cooling device according to an exemplary embodiment of the present invention. Wherein the hollow arrows indicate the general direction of flow of the air flow.

According to some embodiments, the portable detachable spray cooling device 400 may further include a pure water unit 440, one end of the pure water unit 440 may be communicated with a water inlet of the water supply unit, and the other end may be communicated with a cooling tower, for example, for purifying water from a water collecting tray (not shown) inside the cooling tower to provide purified water to the water supply unit 430, in which case, municipal water supply is not required, and water resources may be saved without clogging the spray unit 420 by using internal water circulation.

According to some embodiments, one end of the pure water unit 440 may communicate with the water supply unit inlet and the other end may also communicate with the municipal water supply to provide the purified municipal water supply to the water supply unit 430. In this case, the municipal water supply may be further purified to ensure that the spray unit 420 is not clogged.

It should be noted that the pure water unit 440 may further include a pure water tank for temporarily storing purified internal circulating water or purified municipal water for the portable detachable spray cooling device 400 to be used at any time.

In practical applications, the water supply unit 430 may further include a constant pressure element for maintaining a constant pressure of the water supplied to the spraying unit 420 so as not to cause damage to the spraying unit 420 or reduce the lifespan of the spraying unit 420.

According to some embodiments, portable knock-down spray cooling device 400 may also include a temperature sensor and/or humidity sensor 450, which may be used to sense the temperature and/or humidity of the external environment. The temperature sensor and the humidity sensor can respectively detect the ambient temperature and the ambient humidity and respectively send out a temperature sensing signal and a humidity sensing signal, so that the spray cooling device 400 can be adjusted based on the ambient temperature and/or the ambient humidity, and the labor is saved; moreover, the adjustment based on the environmental parameters is more accurate than the adjustment based on pure manpower, so that the effects of saving water resources and electric power resources can be brought.

According to some embodiments, portable knock-down spray cooler 400 may further include a controller 460, and controller 460 may receive a sensing signal from temperature sensor and/or humidity sensor 450 and, based on the sensing signal, send a control signal to at least one of: an air flow generating unit 410, a spraying unit 420, and a water supply unit 430. The controller 460 may be powered by an ac power source or a dc power source, without limitation. In one example, when the temperature and humidity conditions of the external environment are detected by the sensor 450 to meet the preset requirement for starting the portable detachable spray cooling device 400, the controller 460 may send a starting signal to the airflow generating unit 410, the spraying unit 420 and the water supply unit 430, respectively, so that the portable detachable spray cooling device 400 starts spraying to the inside of the cooling tower. In one example, the sensor 450 detects that the temperature and humidity conditions of the external environment meet a predetermined requirement for reducing the power of the portable detachable spray cooling device 400, and the controller 460 may send signals for reducing the power to the airflow generating unit 410, the spraying unit 420, and the water supply unit 430, respectively, to reduce the spray power of the portable detachable spray cooling device 400; the controller 460 may also only send a signal to the water supply unit 430 to reduce the power, and reduce the amount of water supplied per unit time without changing the amount of air supplied, thereby achieving the goal of reducing the spray power of the portable detachable spray cooling device 400. In one example, the sensor 450 detects that the temperature and humidity conditions of the external environment meet a predetermined requirement for turning off the portable detachable spray cooling device 400, and the controller 460 can send a turn-off signal to the airflow generating unit 410, the spraying unit 420 and the water supply unit 430, respectively, to turn off the portable detachable spray cooling device 400. After closing, the portable detachable spray cooling device 400 can be detached or maintained.

The portable dismounting spray cooling device 400 is controlled based on external environment parameters, the operation power of the portable dismounting spray cooling device 400 and the portable dismounting spray cooling device 400 can be accurately determined when the portable dismounting spray cooling device 400 is started and stopped, and the purpose of assisting the inner spray header to cool the heat exchanger can be achieved, so that the blockage of the inner spray header and a pipeline is reduced, and the cooling capacity of a cooling tower can be further improved.
