Description

Technical Field

[0001] The utility model relates to evaporative air-water cooling equipment. Background Art

[0002] Air-water cooling equipment is widely used for cooling electrical equipment rooms. The temperature in electrical equipment rooms usually needs to be controlled between 5 and 40 degrees to ensure the normal operation and service life of the equipment. Air-water cooling equipment in the prior art mainly uses a circulating water pump to extract a large amount of external water resources for circulating cooling to meet the cooling requirements in electrical equipment rooms. However, this method relies on sufficient external water resources, and in some water-scarce or water-tight environments, it is difficult to achieve effective cooling.

[0003] Traditional air-water cooling equipment usually includes a shell and a heat exchanger. Hot air enters the shell through the hot air inlet, and after heat exchange with the cooling water in the heat exchanger, it forms cold air and is discharged from the cold air outlet. In order to maintain the low temperature of the cooling water, it is usually necessary to use a water pump to continuously draw a large amount of cold water from the outside for circulation. This not only increases energy consumption and operating costs, but may also face the limitation of insufficient external water sources, and cannot meet the use requirements of some specific environments. Utility Model Content

[0004] The utility model aims to provide an evaporative air-water cooling device which can not only meet the cooling demand of an electrical equipment room but also work normally in an environment with scarce water resources.

[0005] The purpose of the utility model is achieved in this way:

[0006] An evaporative air-water cooling device comprises a cooler and an evaporative cooling chamber for cooling water, wherein the cooler comprises a shell and a heat exchanger, wherein the shell is provided with a hot air inlet, a cold air outlet and a condensed water outlet, wherein the heat exchanger is disposed in an inner cavity of the shell, and an air duct is formed between the heat exchanger and the inner wall of the shell;

[0007] One end of the heat exchanger extends out of the shell and is connected to a water inlet pipe, and the other end of the heat exchanger extends out of the shell and is connected to a water return pipe;

[0008] The water inlet of the evaporative cooling bin is connected to the water return pipe, and the water outlet of the evaporative cooling bin is connected to the water inlet pipe;

[0009] A fan is arranged at the cold air outlet.

[0010] By installing a heat exchanger in the shell and using the evaporative cooling tank for water circulation cooling, the heat exchange efficiency is effectively improved, ensuring that the temperature in the electrical equipment room is stable between 5 degrees and 40 degrees. This efficient cooling performance can better protect electrical equipment and extend its service life.

[0011] Traditional air-water cooling equipment relies on a large amount of external water resources for circulation and cooling, such as industrial circulating water or other cooling water in the factory area, and is limited by high water temperature (water temperature requirement ≤33°C), which affects the cooling effect and the operating stability of the cooled electrical equipment. The evaporative cooling bin in this design can cool the hot water, so that the water of the entire system can be recycled, reducing dependence on external water resources. It is particularly suitable for areas with water shortage or water shortage.

[0012] By reducing the use of external water resources, this equipment significantly reduces water consumption and related costs. At the same time, the efficient cooperation of the evaporative cooling bin and the heat exchanger reduces the energy consumption of the system and further reduces the operating cost.

[0013] This equipment is designed to be suitable for various environmental conditions, especially in water-scarce areas or environments with limited water resources, and can still operate efficiently. This wide range of environmental adaptability makes the equipment more widely applicable.

[0014] By introducing the evaporative cooling tank, the equipment can achieve stable water circulation and temperature control without relying on external water resources, ensuring long-term stable operation of the system. At the same time, the optimized design of the evaporative cooling tank and heat exchanger improves the reliability of the system.

[0015] By reducing the reliance on external water resources and reducing energy consumption, this equipment performs outstandingly in terms of energy conservation and environmental protection. The evaporative cooling method of the evaporative cooling bin is more environmentally friendly and helps to reduce the carbon emissions and environmental impact of the entire system.

[0016] The purpose of the utility model can also be solved by the following technical measures:

[0017] Furthermore, the hot air inlet is opened at the top of the shell, the cold air outlet is opened at the side wall of the shell, and the condensed water outlet is opened at the bottom of the shell.

[0018] A condensate outlet is provided at the bottom to discharge the condensate naturally by gravity, which reduces the retention time of the condensate inside the shell, prevents water accumulation, and ensures the normal working efficiency of the heat exchanger and the operating stability of the entire system.

[0019] Furthermore, it also includes a water receiving pan, which is arranged on the shell and below the condensed water outlet, and the water receiving pan is provided with a sewage outlet connected to the outside.

[0020] The water receiving tray is arranged at the bottom of the shell and below the condensation water outlet, which can effectively collect the condensation water discharged from the condensation water outlet, prevent the condensation water from dripping to the outside of the equipment or the ground, and keep the equipment room clean and dry.

[0021] The water collection pan is provided with a sewage outlet connected to the outside, which can discharge the collected condensed water to the outside in time to prevent water accumulation and overflow in the water collection pan, and further ensure the normal operation of the system and the cleanliness of the equipment room.

[0022] The reasonable design of the water tray and drain outlet automates the condensate discharge process, reduces manual intervention and maintenance work, reduces maintenance costs and workload, and improves the overall maintenance efficiency of the system.

[0023] Furthermore, it also includes a water pump, the inlet of the water pump is connected to the water outlet of the evaporative cooling bin, and the outlet of the water pump is connected to the inlet of the water inlet pipe.

[0024] The setting of the water pump ensures that the water cooled in the evaporative cooling bin can be quickly and efficiently transported back to the heat exchanger, achieving rapid water circulation and significantly improving the cooling efficiency and heat exchange efficiency of the entire system.

[0025] The addition of the water pump makes the water circulation process smoother and more continuous, avoiding poor or stagnant water flow, ensuring the stability of the cooling process, and allowing the temperature in the equipment room to always remain between 5 and 40 degrees.

[0026] Through the forced circulation of the water pump, the system can operate under a wider range of environmental conditions and adapt to installation requirements at different altitudes and complex terrains, thus enhancing the environmental adaptability and application scope of the equipment.

[0027] The water pump can be intelligently controlled according to system needs, optimize water flow rate and circulation volume, maximize energy utilization efficiency, and further achieve the goal of energy saving and consumption reduction.

[0028] The use of water pumps makes the control of the water circulation system more precise and reliable, avoids system failures caused by insufficient or excessive water flow, and improves the reliability and service life of the entire system.

[0029] The water pump effectively cooperates with the work of the evaporative cooling bin, so that the cooled water in the evaporative cooling bin can be quickly returned to the heat exchanger, maximizing the cooling capacity of the evaporative cooling bin and improving the cooling efficiency of the overall system.

[0030] Furthermore, a water leakage alarm is provided at the water receiving tray at the position of the highest water level, and the water leakage alarm is electrically connected to the water pump.

[0031] When the water outlet is blocked or the heat exchanger is leaking, the water level in the water tray rises to the water leakage alarm, which immediately sends out an alarm signal to remind maintenance personnel to take measures to prevent the water tray from overflowing.

[0032] The water leakage alarm not only sends out an alarm signal, but also automatically stops the water pump, cuts off the water circulation, prevents more water from flowing into the system, and reduces potential damage. This automated safety protection measure effectively improves the safety and reliability of the system.

[0033] Through the automatic detection and alarm function of the water leakage alarm, maintenance personnel can discover and deal with problems in a timely manner, reducing the workload of daily inspections, improving maintenance efficiency, and reducing equipment operation risks.

[0034] Timely water leakage alarm and water pump stop function prevent equipment damage caused by water flooding, protect the heat exchanger and other key components, and extend the service life of the entire system.

[0035] The beneficial effects of the utility model are as follows:

[0036] The utility model effectively improves the heat exchange efficiency by arranging a heat exchanger in the shell and using the evaporative cooling chamber for water circulation cooling, ensuring that the temperature in the electrical equipment room is stable between 5 degrees and 40 degrees. This efficient cooling performance can better protect the electrical equipment and extend its service life.

[0037] In this utility model, the evaporative cooling bin can cool down the hot water, so that the water of the whole system can be recycled, reducing the dependence on external water resources. It is particularly suitable for areas with water shortage or water shortage. This equipment design is suitable for various environmental conditions, especially in areas with water shortage or limited water resources. It can still operate efficiently. This wide range of environmental adaptability makes the application range of the equipment wider.

[0038] In the utility model, when the water outlet is blocked or the heat exchanger leaks, the water level in the water tray rises to the water leakage alarm, and the water leakage alarm immediately sends out an alarm signal to remind the maintenance personnel to take measures to prevent the water tray from overflowing. In addition, the water leakage alarm not only sends out an alarm signal, but also automatically stops the water pump, cuts off the water circulation, prevents more water from flowing into the system, and reduces potential damage. This automated safety protection measure effectively improves the safety and reliability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0043] Example, combined with Figures 1 to 3 As shown, an evaporative air-water cooling device comprises a cooler 1 and an evaporative cooling chamber 2 for cooling water, the cooler 1 comprises a shell 3 and a heat exchanger 4, the shell 3 is provided with a hot air inlet 31, a cold air outlet 32 ​​and a condensed water outlet 33, the heat exchanger 4 is placed in the inner cavity of the shell 3, and an air duct 34 is formed between the heat exchanger 4 and the inner wall of the shell 3;

[0044] One end of the heat exchanger 4 extends out of the shell 3 and is connected to a water inlet pipe 5, and the other end of the heat exchanger 4 extends out of the shell 3 and is connected to a water return pipe 6;

[0045] The water inlet of the evaporative cooling bin 2 is connected to the water return pipe 6, and the water outlet of the evaporative cooling bin 2 is connected to the water inlet pipe 5;

[0046] A fan 7 is provided at the cold air outlet 32 ​​.

[0047] Furthermore, the hot air inlet 31 is opened at the top of the shell 3 , the cold air outlet 32 ​​is opened at the side wall of the shell 3 , and the condensed water outlet 33 is opened at the bottom of the shell 3 .

[0048] Furthermore, it also includes a water receiving tray 9, which is arranged on the shell 3 and below the condensed water outlet 33, and the water receiving tray 9 is provided with a sewage outlet 91 connected to the outside.

[0049] Furthermore, a water pump 8 is included, the inlet of the water pump 8 is connected to the water outlet of the evaporative cooling bin 2 , and the outlet of the water pump 8 is connected to the inlet of the water inlet pipe 5 .

[0050] Furthermore, a water leakage alarm 10 is provided at the water receiving tray 9 at the position of the highest water level, and the water leakage alarm 10 is electrically connected to the water pump 8 .

[0051] The process of cooling the electrical equipment room with evaporative air-water cooling equipment is as follows:

[0052] Hot air enters the device:

[0053] The hot air in the electrical equipment room enters the inner cavity of the shell 3 of the evaporative air-water cooling device through the hot air inlet 31 on the top of the shell 3.

[0054] Heat exchange process:

[0055] The hot air passes through the heat exchanger 4 in the inner cavity of the housing 3. The cooling water in the heat exchanger 4 absorbs the heat of the hot air, causing the temperature of the hot air to drop. At this time, the hot air is converted into cold air through heat exchange with the heat exchanger 4.

[0056] Cold air output:

[0057] The cold air after the temperature reduction treatment is discharged from the cold air outlet 32 ​​on the side wall of the housing 3, and re-enters the electrical equipment room under the action of the fan 7. The cold air circulates in the equipment room, absorbs the heat in the equipment room, and thus reduces the temperature in the room.

[0058] Hot water discharge:

[0059] After absorbing the heat of the hot air, the cooling water in the heat exchanger 4 increases in temperature and becomes hot water. The hot water is discharged to the evaporative cooling chamber 2 through the return pipe 6 of the heat exchanger 4.

[0060] Evaporative cooling chamber 2 cooling:

[0061] After the hot water enters the evaporative cooling chamber 2, it dissipates heat through evaporation and heat exchange, and the temperature is reduced. The evaporative cooling chamber 2 uses the evaporation principle to remove heat through air flow and water evaporation, so that the hot water is cooled to a suitable temperature.

[0062] Water pump 8 cycles:

[0063] The cooled water flows out through the water outlet of the evaporative cooling bin 2, is pumped by the water pump 8, and is re-sent into the heat exchanger 4 through the water inlet pipe 5, completing a water circulation cycle.

[0064] Condensate management:

[0065] During the cooling process (when the hot air contacts the heat exchanger 4 with a low temperature), the condensed water generated on the outer wall of the heat exchanger 4 flows into the water receiving pan 9 through the condensed water outlet 33 at the bottom of the shell 3. The water receiving pan 9 collects the condensed water and discharges it through the drain outlet 91 connected to the outside to prevent the condensed water from accumulating inside the device.

[0066] Water leakage protection:

[0067] The water receiving pan 9 is provided with a water leakage alarm 10 at the highest water level. When the water outlet is blocked or the heat exchanger 4 leaks, causing the water level of the water receiving pan 9 to rise to the position of the water leakage alarm 10, the water leakage alarm 10 sends an alarm signal to notify the maintenance personnel and automatically stops the water pump 8 to prevent further leakage.

[0068] Through the above process, the evaporative air-water cooling equipment can effectively convert the hot air in the electrical equipment room into cold air, maintain the temperature in the equipment room between 5 degrees and 40 degrees, and ensure the normal operation and safety of the electrical equipment. The entire system is highly efficient and energy-saving, suitable for various environments, especially in water-scarce areas. Through the evaporative cooling of the evaporative cooling bin 2, the recycling of water resources is realized, and the stability and reliability of the system are improved.
