Description

Technical Field

[0001] This invention relates to the field of air conditioning cooling equipment technology, specifically to a data center evaporative cooling technology device. Background Technology

[0002] With the advent of the big data era, people are paying more and more attention to the energy consumption of data center air conditioning systems. Traditional mechanical refrigeration systems are divided into air-cooled and water-cooled types. Air-cooled mechanical chiller units have low cooling efficiency and high energy consumption, and are prone to shutdown under extreme operating conditions; water-cooled mechanical chiller units have lower energy efficiency and are not easy to adjust the outlet water temperature during use.

[0003] Currently, indirect evaporative cooling chillers are increasingly used as natural cold sources in data centers. However, their temperature drop is limited by outdoor weather conditions, making it essential to expand the applicability of indirect evaporative cooling. Employing dew point indirect evaporative cooling technology can significantly increase the cooling driving force, allowing the temperature of the treated air to exceed the wet-bulb temperature and even approach the dew point temperature. Therefore, this invention proposes a data center evaporative cooling technology device to improve cooling efficiency and expand its applicability to varying environmental temperatures and humidity. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a data center evaporative cooling technology device that employs dew point indirect evaporative cooling technology and cold air collection and recycling methods, significantly improving cooling efficiency and the applicable range of ambient temperature and humidity.

[0005] The dew point indirect evaporative cooling technology is adopted. Through the cooperation of a blower and a dew point indirect evaporative cooler, the blower blows the gas in the main body of the computer room into the installation cavity through the air inlet pipe, where it is initially cooled by the surface cooler. When the water pump is started, it delivers water to the first water storage tank through the water pumping pipe and the water supply pipe, and sprays it onto the dew point indirect evaporative cooler through the first nozzle to perform isohumid cooling on the dew point indirect evaporative cooler. This improves the airflow cooling efficiency, enhances the heat dissipation performance of the main body of the computer room, and improves the applicability of dew point indirect evaporative cooling.

[0006] By adopting a cold air collection and utilization method, the airflow passing through the surface cooler and the dew point indirect evaporative cooler can pass through the installation chamber, so that the water flow discharged into the installation chamber is cooled by the water flow through the packing material, thereby further cooling the water flow pumped into the main body of the machine room, and the water flow sprayed on the dew point indirect evaporative cooler can also be cooled more, further improving the cooling efficiency and expanding the temperature and humidity applicable range of indirect evaporative cooling technology.

A blower is fixedly installed on the inner bottom wall of the fixed compartment. An exhaust pipe connected to the lower end of the fixed compartment is connected to the supporting base plate. A filter assembly is disposed inside the supporting base plate.

[0009] Furthermore, there are two water supply pipes, which are symmetrically distributed on the left and right sides. The inlet end of each water supply pipe passes through the supporting base plate and is connected to the water tank.

[0010] Furthermore, the support base plate has two first air guide holes, one end of which is connected to the mounting cavity and the air inlet pipe respectively, and the mounting cavity has two second air guide holes, one end of which is connected to the exhaust pipe and the mounting cavity respectively.

[0011] Furthermore, the inner bottom wall of the fixed chamber is provided with a ventilation hole located on the left side of the exhaust pipe, and the first air guide hole is connected to the inner top wall of the fixed chamber.

[0012] Furthermore, the filter assembly includes two filter screens, and an air inlet is provided inside the support base plate, with one end connected to the exhaust pipe. Both filter screens are fixedly connected to the inside of the air inlet, and an activated carbon plate is fixedly connected to the inside of the air inlet.

[0013] Furthermore, the evaporative cooling chiller unit includes an installation chamber with one end fixedly connected to the inside of the installation cavity. A second water storage tank is fixedly connected to the inside of the installation chamber. A second nozzle is connected to the lower end of the second water storage tank. The inside of the installation chamber is filled with packing material. An installation groove with one end connected to the installation cavity is opened inside the support base plate. An exhaust fan is fixedly installed inside the installation groove.

[0014] Furthermore, the inner bottom wall of the installation chamber is conical, and a drain hole is provided on the inner bottom wall of the installation chamber, one end of which is connected to the water tank.

[0015] Furthermore, the inner bottom wall of the installation chamber is provided with a through hole located above the packing material, and the interior of the support base plate is provided with a perforation at one end that is connected to the installation groove and the main body of the machine room respectively.

[0016] Furthermore, there are two drain pipes, which are symmetrically distributed on the left and right sides. The outlet ends of the two drain pipes penetrate the supporting base plate and are connected to the second water storage tank.

This device has the advantage of high evaporative cooling efficiency and solves the problem of limited applicable environmental temperature and humidity range due to poor cooling efficiency, thereby achieving energy-saving, low-carbon, green, and environmentally friendly effects for data centers.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1 An evaporative cooling technology device for a data center in this embodiment includes a supporting base plate 1. A computer room body 2 is provided at the upper end of the supporting base plate 1. A drain pipe 3 is connected to the outside of the computer room body 2, with one end connected to the supporting base plate 1. A water supply pipe 5 is connected to the outside of the computer room body 2, with one end connected to the supporting base plate 1. An evaporative cooling air cooler 4 is provided inside the supporting base plate 1.

[0028] In this embodiment, the air delivered to the main body of the computer room 2 is cooled twice by the evaporative cooling air cooler unit 4 and then delivered back to the main body of the computer room 2, forming a circulating cooling channel, which improves the cooling efficiency of the main body of the computer room 2. It can also cool the water flow delivered to the main body of the computer room 2, further improving the cooling efficiency.

[0029] Example 2: Please refer to Figure 2-4In this embodiment, the evaporative cooling air cooler unit 4 includes an installation cavity 41 with one end connected to the inside of the support base plate 1. A surface cooler 42 is disposed between the inner bottom wall and the inner top wall of the installation cavity 41 and is located on the support base plate 1. A first water storage tank 45 is fixedly installed on the inner top wall of the installation cavity 41. The lower end of the first water storage tank 45 is connected to a first nozzle 44. A water tank 415 is fixedly installed inside the support base plate 1. A water pump 414 is fixedly installed on the inner top wall of the water tank 415. The water inlet of the water pump 414 is connected to a water suction pipe 413 located inside the water tank 415. The outlet of 414 is connected to a water pipe 47 that passes through the water tank 415 and is connected to the first water storage tank 45. An evaporative cooling chiller 46 located on the support base plate 1 is installed inside the mounting cavity 41. A dew point indirect evaporative cooler 416 is installed on the evaporative cooling chiller 46. A fixed chamber 411 is fixedly connected inside the mounting cavity 41. A blower 410 is fixedly installed on the inner bottom wall of the fixed chamber 411. An exhaust pipe 412 connected to the lower end of the fixed chamber 411 is connected to the support base plate 1. A filter assembly 49 is installed inside the support base plate 1.

[0030] In this embodiment, the activated blower 410 blows the gas inside the main body 2 of the computer room into the installation cavity 41 through the air inlet pipe 48, where it is initially cooled by the surface cooler 42. When the activated water pump 414 delivers water to the first water storage tank 45 through the water pumping pipe 413 and the water supply pipe 47, it sprays water onto the dew point indirect evaporative cooler 416 through the first nozzle 44 to perform isohumid cooling on the dew point indirect evaporative cooler 416, thereby improving the airflow cooling efficiency and improving the heat dissipation performance of the main body 2 of the computer room.

[0031] There are two water supply pipes 5, which are symmetrically distributed on the left and right. The inlet end of the water supply pipe 5 passes through the supporting base plate 1 and is connected to the water tank 415. The outlet end of the water supply pipe 5 is connected to the input end of the air conditioning equipment in the main body of the machine room 2.

[0032] In addition, the support base plate 1 has two first air guide holes, one end of which is connected to the mounting cavity 41 and the air inlet pipe 48 respectively. The mounting cavity 41 has two second air guide holes, one end of which is connected to the exhaust pipe 43 and the mounting cavity 41 respectively. The circulating cooling airflow enters the main body 2 of the computer room through the first air guide holes and then returns to the mounting cavity 41 through the second air guide holes.

[0033] Secondly, the bottom wall of the fixed chamber 411 is provided with a ventilation hole located on the left side of the exhaust pipe 412. The first air guide hole is connected to the top wall of the fixed chamber 411, so that the airflow after secondary cooling enters the fixed chamber 411 through the ventilation hole and is transported to the main body of the computer room 2 for circulation cooling.

[0034] Then, the filter assembly 49 includes two filter screens 492. An air inlet 493 is opened inside the support base plate 1, with one end connected to the exhaust pipe 412. Both filter screens 492 are fixedly connected to the inside of the air inlet 493. An activated carbon plate 491 is fixedly connected to the inside of the air inlet 493, so that the airflow drawn into the main body of the computer room 2 can be filtered by the filter screens 492 and the activated carbon plate 491 in sequence.

[0035] Example 3: Please refer to Figure 5 In this embodiment, the evaporative cooling chiller unit 46 includes an installation chamber 461 with one end fixedly connected to the inside of the installation cavity 41. A second water storage tank 462 is fixedly connected to the inside of the installation chamber 461. A second nozzle 465 is connected to the lower end of the second water storage tank 462. A packing material 466 is provided inside the installation chamber 461. An installation groove 464 with one end connected to the installation cavity 41 is opened inside the support base plate 1. An exhaust fan 463 is fixedly installed inside the installation groove 464.

[0036] In this embodiment, since the airflow passing through the surface cooler 42 and the dew point indirect evaporative cooler 416 can pass through the installation chamber 461, the water flow discharged into the installation chamber 461 is cooled by the water flow through the packing 466, making the water flow pumped into the main body 2 of the machine room even cooler, and the water flow sprayed onto the dew point indirect evaporative cooler 416 can also be cooled even more, further improving the cooling efficiency.

[0037] The inner bottom wall of the installation chamber 461 is conical, and a drain hole 467 is provided on the inner bottom wall of the installation chamber 461, which is connected to the water tank 415 at one end. This allows a water film to form on the surface of the packing 466, and the water flow is cooled by the air. The air and the water film exchange heat and moisture, and the water temperature drops. Then, the water flows into the water tank 415 through the drain hole 467.

[0038] In addition, the inner bottom wall of the installation chamber 461 has a through hole located above the packing 466, and the inside of the support base plate 1 has a perforation that connects one end to the installation groove 464 and the main body of the machine room 2, so that the cooled air can be drawn back into the main body of the machine room 2 for secondary cooling.

[0039] Secondly, there are two drain pipes 3, which are symmetrically distributed on the left and right. The water outlet of the two drain pipes 3 passes through the support base plate 1 and is connected to the second water storage tank 462. The water inlet of the drain pipes 3 is connected to the output of the air conditioning equipment in the main body 2.

[0040] The overall working principle of the above embodiments is as follows:

[0041] The activated blower 410 blows air from the main body 2 of the computer room into the installation cavity 41 through the air inlet pipe 48, where it is initially cooled by the surface cooler 42. Meanwhile, the activated water pump 414 delivers water to the first water storage tank 45 through the water suction pipe 413 and the water supply pipe 47, and sprays it onto the dew point indirect evaporative cooler 416 through the first nozzle 44 to perform isohumid cooling on the airflow passing through the dew point indirect evaporative cooler 416, thereby improving the airflow cooling efficiency. The airflow, after dual cooling, can be re-delivered into the main body 2 of the computer room by the activated blower 410, improving the heat dissipation performance of the main body 2 and thus enhancing the applicability of the dew point indirect evaporative cooling system. Furthermore, due to the surface cooler... The airflow of the device 42 and the dew point indirect evaporative cooler 416 can pass through the installation chamber 461, so that the water flowing into the installation chamber 461 is cooled by the water flow passing through the packing 466 and forming a water film on the surface of the packing 466. After the water flow is cooled by the cold air, the cold air after the air and the water film exchange heat and moisture will be delivered to the main body of the machine room 2 by the activated exhaust fan 463 for further cooling. At the same time, the water flow will also be cooled by the passing cold air, making the water flow pumped into the main body of the machine room 2 even cooler, and the water flow sprayed on the dew point indirect evaporative cooler 416 will also be cooled even more, further improving the cooling efficiency, so as to achieve the effects of energy saving, low carbon, green and environmental protection.
