Description

Technical Field

[0001] The utility model belongs to the technical field of data room, and in particular relates to a temperature-controlled pumping natural cold source device for a room. Background Art

[0002] At present, with the continuous improvement of the integration of data equipment, its heat generation is also increasing sharply. At the same time, due to the explosive growth of information application demand and the scarcity of construction land and other factors, the concentration of equipment in existing computer rooms is getting higher and higher, which has caused the continuous increase in demand for refrigeration and air conditioning equipment. However, there is no space in some computer rooms to install air-conditioning energy-saving equipment. Installing only a small amount of air-conditioning energy-saving equipment is just a drop in the bucket, resulting in low energy-saving efficiency.

[0003] Nowadays, it is more popular to introduce natural cooling sources to increase the cooling capacity in the computer room and replace the air conditioning equipment with compressors during some periods of time. This energy-saving method has been unanimously recognized by users due to its high energy-saving efficiency and high system cost-effectiveness. The energy efficiency ratio of computer room precision air conditioning is generally around 3-3.5, while the energy efficiency ratio of natural cooling source energy-saving system can reach around 8-25, which is much higher than the computer room precision air conditioning system.

[0004] A Chinese patent with application number CN202120988942.0 discloses a cooling system using a natural cold source for constant temperature control. The cooling system using the natural cold source includes: a computer room cooling device, a constant temperature layer, an outdoor cooling device and a controller. The constant temperature layer has a built-in cold medium. The computer room cooling device can exchange heat with the outside natural air through the evaporation of tap water using a wet curtain; the computer room cooling device can exchange heat with the outside natural air outdoor cooling device by utilizing the evaporation of the wet curtain, and can be connected to the buried water pipe by utilizing the evaporation of the wet curtain; the controller controls the heat exchange between the computer room cooling device and the cold medium and / or the outdoor cooling device according to the outdoor air temperature sensor.

[0005] As the applicant conducted further research, it was found that since the technical solution failed to improve the structure of the outdoor cooling mechanism itself, although it could reduce the temperature in the machine room to a certain extent, the outdoor cooling mechanism was relatively close to the residential area as a whole, and the high-speed operation of the built-in fan generated a lot of noise, which would affect the life and work of outdoor residents. If the outdoor cooling mechanism was isolated, such as adding sound insulation cotton, the project workload would be large and the effect would not be ideal. Utility Model Content

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A temperature-controlled pumping natural cooling source device for a machine room, comprising:

[0008] The outdoor cooling mechanism is arranged outside the wall;

[0009] A fan is arranged inside the wall;

[0010] An air duct runs through the wall and connects the outdoor cooling mechanism and the fan;

[0011] Under the action of the fan, the outdoor air is cooled by the outdoor cooling mechanism and then enters the machine room through the air duct.

[0012] Furthermore, a dehumidification component is connected to the rear end of the fan.

[0013] Furthermore, it also includes a first air-blocking valve, which is connected to the air outlet of the dehumidification component.

[0014] Furthermore, a mounting shell fixedly connected to the wall is provided in the machine room, and the fan and dehumidification components are placed on the mounting shell.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] This technical solution adopts the method of modifying the traditional outdoor cooling mechanism and moving the built-in fan into the machine room.

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Among them, the drawings are only used for exemplary explanations, and they only show schematic diagrams rather than actual drawings, and cannot be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted, and the same or similar reference numerals in the drawings of the embodiments of the utility model correspond to the same or similar parts; in the description of the utility model, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer" and the like appear, the directions or positional relationships indicated are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, so the terms describing the positional relationship in the drawings are only used for exemplary explanations, and cannot be understood as limitations on this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] like Figure 1 - Figure 2 As shown, a temperature-controlled pumping natural cooling source device for a machine room of the utility model comprises an outdoor cooling mechanism 1, a fan 2 separated from the outdoor cooling mechanism 1, and an air guide duct 3;

[0029] The outdoor cooling mechanism 1 is arranged outside the wall 8, and the fan 2 is arranged inside the wall 8;

[0030] The air duct 3 penetrates the wall 8 and connects the outdoor cooling mechanism 1 and the fan 2;

[0031] Under the action of the fan 2, the outdoor air is cooled by the outdoor cooling mechanism 1 and then enters the machine room through the air duct 3. The traditional outdoor cooling mechanism 1 is modified and the built-in fan 2 is moved into the machine room. Since the fan 2 is indoors, the noise generated is isolated by the wall 8, and the noise heard outdoors is greatly reduced compared to before the modification, reducing the impact of the outdoor noise of the machine room on residents. Before the modification, according to the test, the original noise outside the machine room was about 83 decibels. After it was moved indoors and modified, if a certain EC type fan 2 is used indoors, the noise outside the machine room can be reduced to about 60 decibels, which can reduce the impact of the noise of the fan 2 on residents.

[0032] According to the standard requirements of the computer room, the maximum air humidity in the computer room cannot exceed 70%, otherwise it will have an adverse effect on the electrical equipment in the computer room. In the rainy season, the outdoor air humidity becomes relatively high. If the natural cold source air is directly drawn in, the humidity in the computer room will increase. In addition, due to the effect of the outdoor cooling mechanism 1, the air humidity rises to about 80%, exceeding the standard requirements. A dehumidification component 4 can be connected to the rear end of the fan 2 to absorb moisture in the air. After experimental testing, the air humidity entering the computer room dropped below 60%, and the humidity in the computer room remained within a reasonable range.

[0033] In addition, after the temperature in the machine room reaches the set value, the cold source device of the utility model can be in a shutdown state. In order to avoid indoor and outdoor air convection in the machine room, causing the indoor temperature to rise too quickly, a first air-closing valve 5 can be set, and the first air-closing valve 5 is connected to the tail air outlet of the dehumidification component 4. A second air-closing valve 80 can also be set on the air duct 3. The first air-closing valve 5 and the second air-closing valve 80 have a rotating baffle. When the cold source device is in operation, the flowing air blows the rotating baffle and is in an open state. When the cold source device is stopped, the rotating baffle shields the air outlet of the air duct or the dehumidification component 4 under the action of its own gravity. The first air-closing valve 5 and the second air-closing valve 80 can also be electrically controlled, with a motor structure added, and the motor is used as a driving force to control the opening and closing of the rotating baffle. In this way, the reliability of the rotating baffle in place can be guaranteed, and the air-closing valve is prevented from leaking or the rotating baffle cannot be opened.

[0034] In addition, a mounting shell 6 fixedly connected to the wall 8 is provided in the machine room, and components such as the fan 2 and the dehumidification assembly 4 are placed in the mounting shell 6 to combine them into a whole.

[0035] In addition, a flange 30 is provided at the connection between the outdoor cooling mechanism 1 and the air guide duct 3 .

[0036] A maintenance platform 7 fixed to the wall 8 is provided outside the machine room, and the outdoor cooling mechanism 1 is placed on the maintenance platform 7. The maintenance platform 7 can be connected to the wall 8 through inclined ribs 70 and expansion screws, and the maintenance platform 7 can be connected to the inclined ribs 70 by welding, clamping, plugging, etc. The connection method between the maintenance platform 7 and the inclined ribs 70 can be set as needed. The outdoor cooling mechanism 1 is hoisted outside the machine room by the above method.

[0037] Among them, a number of anti-vibration feet 10 are arranged at the bottom of the outdoor cooling mechanism 1. It is worth noting that the anti-vibration feet 10 can be made of rubber materials or other materials with buffering effects, which can reduce the wear of the maintenance platform 7 and improve the mechanical stability.

[0038] like Figure 2 As shown, the outdoor cooling mechanism 1 can adopt a water-cooling device, which has a wet curtain 11 on at least one side. Through the action of the fan 2, a certain negative pressure is generated in the outdoor cooling mechanism 1, and the external air is drawn into the outdoor cooling mechanism 1. In this process, the air passes through the wet curtain 11, and at the same time, the water pump arranged inside the outdoor cooling mechanism 1 transports the water stored in the outdoor cooling mechanism 1 to the water distribution pipe on the wet curtain 11. The contact surface of the entire wet curtain 11 will be evenly infiltrated by water, absorbing a large amount of heat in the air, so that the air passing through the wet curtain 11 is cooled and filtered at the same time, and enters the machine room through the air guide duct 3, thereby reducing the indoor temperature. Specifically, the wet curtain 11 can be arranged in three groups. In addition, each group of wet curtains 11 can be hinged to the side of the outdoor cooling mechanism 1. Such an arrangement can facilitate the replacement of the wet curtain 11 and the cleaning of impurities inside the outdoor cooling mechanism 1.

[0039] Sensors are installed at multiple locations in the machine room to monitor the temperature and humidity in the machine room, and exhaust fans 2 and air valves are installed on the wall 8 of the machine room to cooperate with the natural cooling source device to form a circulating temperature control system for the machine room. When the temperature of the machine room rises to the set temperature reduction range, in addition to the operation of the natural cooling source device, the over-temperature gas in the machine room is discharged to the outside through the opening of the air valve by the exhaust fan 2. Specifically, the exhaust fan 2 is installed on the top of the machine room or in an unrestricted place.

[0040] The intelligent control cabinet in the computer room receives the temperature, humidity and other information from the indoor and outdoor sensors at the same time for judgment. The control cabinet can simultaneously start the exhaust fan 2 and / or the indoor air conditioner and turn on the natural cooling source device to control the temperature;

[0041] The cooling system using a natural cold source also includes a data room and an air temperature sensor in the room. The room cooling equipment and the room air temperature sensor are respectively arranged in the data room. The controller controls one or more outdoor cooling equipment to exchange heat with the room cooling equipment according to the air temperature sensor in the room.

[0042] The above are only embodiments of the utility model. The common sense such as the known specific structures and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field are aware of all the common technical knowledge in the technical field to which the utility model belongs before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement the scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for the ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
