Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to an in-row computer room air conditioner. Background Art

[0002] With the advent of the big data era, the capacity and heat dissipation of servers have also increased rapidly, and the development of data centers has entered a new stage. In-row computer room air conditioners focus on the servers themselves and directly send cold air into the servers to adjust the temperature of the servers. Compared with traditional air conditioners, they can better solve the problem of local hot spots in servers. Therefore, more and more data centers choose to use in-row computer room air conditioners to maintain the temperature of server cabinets.

[0003] In-row computer room air conditioners are installed between server cabinets and dissipate heat directly near the heat source, so they have the characteristic of a narrow body width. In traditional in-row computer room air conditioners, the filter is installed inside the unit. Affected by the internal space of the unit, the filter is not easy to install. And the air inlet and outlet methods are mostly front and rear air inlet and outlet. Affected by the body width, the air inlet and outlet area is limited.

[0004] Due to the technical problems in the in-row computer room air conditioners in the prior art, such as limited air inlet and outlet area and inability to change the size of the air inlet and outlet area as needed, the present invention studies and designs an in-row computer room air conditioner. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the in-row computer room air conditioners in the prior art, such as limited air inlet and outlet area and inability to change the size of the air inlet and outlet area as needed, resulting in the cooling capacity not meeting the requirements of the cabinet servers, so as to provide an in-row computer room air conditioner.

[0041] In some embodiments,

[0042] When the air inlet is arranged on the first side plate, or the air inlet and the first side plate are on the same side and adjacent, the first side plate is divided into two upper and lower split side plates, and the two upper and lower split side plates are connected by an intermediate cross beam. The air inlet is also divided into a first air inlet arranged on the upper side plate and a second air inlet arranged on the lower side plate. The filtering structure is also divided into two upper and lower split filter meshes. The split filter mesh on the upper side is arranged opposite to the first air inlet and can change with the change of the size of the first air inlet. The split filter mesh on the lower side is arranged opposite to the second air inlet and can change with the change of the size of the second air inlet.

[0043] In some embodiments,

[0044] When the row-intercolumn computer room air conditioner further includes a top plate and a base, the row-intercolumn computer room air conditioner further includes a first bracket, a second bracket, a third bracket and a fourth bracket.

[0045] In some embodiments,

[0046] The structures of the first bracket, the second bracket and the third bracket are all Z-shaped sheet metal parts; the structure of the fourth bracket is a U-shaped sheet metal part.

[0047] The row - type computer room air conditioner provided by the present invention has the following beneficial effects:

[0048] 1. By setting the air inlet and / or air outlet on the first side plate or the second side plate of the row - type computer room air conditioner, or at a position on the same side as and adjacent to the first or second side plate, a side - return - side - discharge structure is formed. Compared with the prior - art solution where the air inlet is set on the back panel and the air outlet is set on the front panel, since the areas of the first and second side plates are much larger than those of the front panel and the back panel, the area of the air inlet can be made much larger than the area of the original air inlet set on the back panel, and the area of the air outlet can be made much larger than the area of the original air outlet set on the front panel. Thus, the air - inlet area and the air - outlet area of the row - type computer room air conditioner are effectively increased, the heat - exchange efficiency of the row - type computer room air conditioner is improved. Also, by setting the sizes of the air inlet and the air outlet to be changeable, the sizes of the air inlet and the air outlet can be adjusted according to the actual heat - exchange amount, so that the refrigeration efficiency is greatly improved compared with the original row - type air conditioner, ensuring that the refrigeration capacity meets the requirements of the cabinet servers, and the heat - exchange power can also be adjusted according to the actual needs to adapt to the internal environment of the computer room, thereby improving the energy - efficiency value of the heat - exchange in the row - type computer room space;

[0049] 2. The present invention also sets a filtering structure outside the air inlet. Since the air inlet and outlet are set on the first and / or second side plates, compared with the prior - art solution where the air inlet and outlet are set on the front panel and the back panel, in the original structure, due to the narrow areas of the front panel and the back panel, the filter - net structure can only be set inside the row - type air conditioner, otherwise it will affect the function of opening the front panel and the side panel for internal maintenance. The present invention effectively sets the filtering structure outside the first and / or second side plates, which is convenient for the installation of the filtering structure and does not affect the internal maintenance function of the row - type air conditioner; and the filtering structure can change its filtering area by movement, enabling the filtering structure to adapt to the change in the area of the air inlet and change the filtering area accordingly. Therefore, the area of the filtering structure can be changed according to the actual needs to meet the requirements of a large air - inlet volume or a small air - inlet volume, so as to adapt to the internal environment of the computer room and improve the energy - efficiency value of the heat - exchange in the row - type computer room space.

Without further statement, the above terms have no special meaning, and thus should not be construed as limiting the protection scope of the present invention.

[0072] As shown in FIGS. 1-6, the present invention provides an in-row computer room air conditioner, wherein:

[0073] The in-row computer room air conditioner is disposed between two adjacent rows of server cabinets. The in-row computer room air conditioner includes a front panel 1, a rear panel 2, a first side panel 3 and a second side panel 4. The front panel 1 and the rear panel 2 are oppositely disposed, the first side panel 3 and the second side panel 4 are oppositely disposed, the front panel 1, the rear panel 2, the first side panel 3 and the second side panel 4 enclose an internal cavity, and an evaporator 15 and a fan (and preferably also structures such as a compressor 16, an oil separator 17, an electrical box 18, a humidifier 19 and a liquid level switch 20, etc.) can be placed in the internal cavity. Moreover, the area of any one of the first side panel 3 and the second side panel 4 is larger than the area of any one of the front panel 1 and the rear panel 2;

[0074] The in-row computer room air conditioner includes an air inlet 5 and an air outlet 6. The air inlet 5 is disposed on one of the first side panel 3 and the second side panel 4, or the air inlet 5 is disposed at a position on the same side and adjacent to one of the first side panel 3 and the second side panel 4. The air outlet 6 is disposed on one of the first side panel 3 and the second side panel 4, or the air outlet 6 is disposed at a position on the same side and adjacent to one of the first side panel 3 and the second side panel 4. Moreover, the size of the air inlet 5 can be changed, and / or the size of the air outlet 6 can also be changed.

[0075] By arranging the air inlet and / or air outlet on the first side plate or the second side plate of the in-row computer room air conditioner, or at a position on the same side as and adjacent to the first or second side plate, a side-return and side-outlet structure is formed. Compared with the prior art solution where the air inlet is arranged on the back panel and the air outlet is arranged on the front panel, since the areas of the first and second side plates are much larger than those of the front panel and the back panel, the area of the air inlet can be made much larger than the area of the air inlet arranged on the back panel in the original design, and the area of the air outlet can be made much larger than the area of the air outlet arranged on the front panel in the original design. Thus, the air inlet area and the air outlet area of the in-row computer room air conditioner are effectively increased, the heat exchange efficiency of the in-row computer room air conditioner is improved, and by setting the sizes of the air inlet and the air outlet to be changeable, the sizes of the air inlet and the air outlet can be adjusted according to the actual heat exchange amount. Therefore, compared with the original in-row air conditioner, the refrigeration efficiency is greatly improved, and the heat exchange power can also be adjusted according to actual needs to adapt to the internal environment of the computer room and improve the energy efficiency value of the heat exchange in the in-row computer room space.

[0076] The beneficial effects of the present invention are as follows:

[0077] 1. The present invention provides a new in-row cabinet air conditioner. By arranging the air inlet and outlet on the side plate structure, the air inlet and outlet mode is changed to form a side-outlet and side-return air inlet and outlet mode, which improves the refrigeration efficiency. The areas of the air inlet and outlet can be adjusted according to the actual working conditions, which can ensure refrigeration while reducing power consumption and improving the energy efficiency of the air conditioner. The side-outlet air outlet mode can directly blow on the cabinet, more effectively refrigerate the cabinet, and the increased air inlet and outlet areas can effectively improve the refrigeration efficiency.

[0078] 2. The double-layer filter screen structure provided by the present invention can adjust the air inlet area as needed, which can ensure refrigeration while reducing power consumption and improving the energy efficiency of the air conditioner.

[0079] 3. The new filter screen installation structure of the present invention changes the installation position and structure of the traditional filter screen, that is, installs the filter screen outside the air inlet, which is beneficial to the installation and disassembly of the filter screen, can effectively improve the assembly efficiency, and is also convenient for after-sales replacement of the filter screen.

[0080] In some embodiments,

[0081] The in-row computer room air conditioner has a cuboid structure and further includes a top plate 7 and a base 8. The first side plate 3 faces one row of server cabinets, the second side plate 4 faces another adjacent row of server cabinets, the front panel 1 is located at the front side and is a user operation panel, the top plate 7 is located at the top of the cuboid structure and is respectively connected to the first side plate 3, the second side plate 4, the front panel 1 and the back panel 2, and the base 8 is located at the bottom of the cuboid structure and is respectively connected to the first side plate 3, the second side plate 4, the front panel 1 and the back panel 2; the sizes of the air inlet 5 and the air outlet 6 can both be changed according to actual requirements.

[0082] This is the preferred structural form of the in-row computer room air conditioner of the present invention. By forming a cuboid structural form, it can effectively adapt to the in-row space of adjacent server cabinets. This space is a long and narrow space. The front panel is located at the front side and is provided with a user operation panel, which is convenient for users to control. The first and second side plates face two opposite rows of server cabinets respectively. Since the air inlet and the air outlet are arranged on the side surface, the areas of the air inlet and the air outlet are effectively increased, the air intake volume and the air outlet volume are increased, and the refrigeration effect on the server cabinets is enhanced. The air inlet and the air outlet can be changed according to actual requirements, so that the sizes of the air inlet and the air outlet can be effectively adjusted according to the actual working conditions (such as the temperature of the server cabinets and the temperature of the indoor environment) to select the most suitable air intake and air outlet volumes to refrigerate the server cabinets, ensuring effective refrigeration while improving the energy efficiency of the air conditioner and saving energy consumption.

[0083] In some embodiments,

[0084] When both the air inlet 5 and the air outlet 6 are arranged on the first side plate 3, or when the air inlet 5 and the air outlet 6 are both on the same side as and connected to the first side plate 3, the first side plate 3 can move to increase or decrease the size of the air inlet 5 and / or increase or decrease the size of the air outlet 6;

[0085] When both the air inlet 5 and the air outlet 6 are arranged on the second side plate 4, or when the air inlet 5 and the air outlet 6 are both on the same side as and connected to the second side plate 4, the second side plate 4 can move to increase or decrease the size of the air inlet 5 and / or increase or decrease the size of the air outlet 6;

[0086] When the air inlet 5 is provided on the first side plate 3, or the air inlet 5 and the first side plate 3 are on the same side and are adjacent, and the air outlet 6 is provided on the second side plate 4, or the air outlet 6 and the second side plate 4 are on the same side and are adjacent, the first side plate 3 can move to increase or decrease the size of the air inlet 5, and the second side plate 4 can move to increase or decrease the size of the air outlet 6;

[0087] When the air inlet 5 is provided on the second side plate 4, or the air inlet 5 and the second side plate 4 are on the same side and are adjacent, and the air outlet 6 is provided on the first side plate 3, or the air outlet 6 and the first side plate 3 are on the same side and are adjacent, the second side plate 4 can move to increase or decrease the size of the air inlet 5, and the first side plate 3 can move to increase or decrease the size of the air outlet 6.

[0088] This is a preferred structural form for changing the area of the air inlet and air outlet of the present invention.

[0100] This is the preferred structural form of the first side plate and the second side plate of the present invention, so as to be able to change the area sizes of the air inlet and the air outlet through movement. When the air inlet is provided on the first side plate or at a position on the same side as and in contact with the first side plate, the first side plate is a foldable structure, and the area of the air inlet is increased or decreased by folding and contracting or expanding.

[0101] In some embodiments,

[0102] When both the air inlet 5 and the air outlet 6 are provided on the first side plate 3, or when the air inlet 5 and the air outlet 6 are on the same side as and in contact with the first side plate 3, the first side plate 3 is an elastic structure, so as to increase or decrease the size of the air inlet 5 and / or increase or decrease the size of the air outlet 6 by elastic compression or elastic stretching;

[0103] When both the air inlet 5 and the air outlet 6 are provided on the second side plate 4, or when the air inlet 5 and the air outlet 6 are on the same side as and in contact with the second side plate 4, the second side plate 4 is an elastic structure, so as to increase or decrease the size of the air inlet 5 and / or increase or decrease the size of the air outlet 6 by elastic compression or elastic stretching;

[0107] In some embodiments,

[0108] A filtering structure 9 is further arranged outside the air inlet 5. When the air inlet 5 is arranged on the first side plate 3 or the air inlet 5 and the first side plate 3 are on the same side and adjacent, the filtering structure 9 is arranged on the side of the first side plate 3 away from the internal cavity, that is, on the outside of the row - type computer room air conditioner, and the filtering structure 9 is arranged opposite to the air inlet 5 so as to completely cover the air inlet 5, so that the air flow first passes through the filtering structure 9 and then enters the internal cavity through the air inlet 5.

[0109] When the air inlet 5 is arranged on the second side plate 4 or the air inlet 5 and the second side plate 4 are on the same side and adjacent, the filtering structure 9 is arranged on the side of the second side plate 4 away from the internal cavity, that is, on the outside of the row - type computer room air conditioner, and the filtering structure 9 is arranged opposite to the air inlet 5 so as to completely cover the air inlet 5, so that the air flow first passes through the filtering structure 9 and then enters the internal cavity through the air inlet 5.

[0110] The present invention also arranges a filtering structure on the outside of the air inlet. Since the air inlet and outlet are arranged on the first and / or second side panels, compared with the original solution in which the air inlet and outlet are arranged on the front panel and the back panel, the original structure has a narrower area of the front panel and the back panel, and its filter structure can only be arranged inside the inter-row air conditioner, otherwise it will affect the function of opening the front panel and the side panel for internal maintenance. The present invention effectively arranges the filtering structure on the outside of the first and / or second side panels, which can facilitate the installation of the filtering structure and will not affect the maintenance function inside the inter-row air conditioner.

[0111] In some embodiments,

[0112] The filter structure 9 can change its filter area by movement to match the size of the air inlet 5 after the area is changed, so as to completely cover the air inlet 5. When the area of the air inlet 5 increases, the area of the filter structure 9 also increases, and when the area of the air inlet 5 decreases, the area of the filter structure 9 also decreases. The filter structure of the present invention can change its filter area by movement, so that the filter structure can adapt to the change of the area size of the air inlet and change the filter area. Therefore, the area of the filter structure can be changed according to actual needs to meet the needs of large or small air intake, to adapt to the internal environment of the machine room, and to improve the energy efficiency value of heat exchange between rows of machine room space.

[0113] The present invention proposes a side-outlet and side-return row-to-row machine room air conditioner with an easy-to-install filter. The filter of this structure is installed on both sides (outside) of the unit and fixed with a bracket, which is easy to install and remove. And the size of the filter can be adjusted according to the actual required air inlet area. This structure also increases the air inlet and outlet area and improves the cooling efficiency.

[0114] The traditional air inlet and outlet mode of the row-to-row computer room air conditioner is generally front-to-back air inlet and outlet (the air inlet and outlet mode is as follows Figure 1-1 , 1-2and 1-3), that is, the air enters the back door and the air exits the front door. The air enters the unit through the back door, flows to the evaporator after being filtered by the coarse filter, and then enters the fan chamber after being cooled by the evaporator. Finally, the cooled air is sent out from the front door by the fan, thereby realizing refrigeration. The front and rear doors of the unit are hollowed out through sheet metal processes such as honeycomb holes or shutters, so that air can enter and exit from the front and rear doors. Therefore, the filter can only be installed inside the unit. However, since the inter-row computer room air conditioner needs to be installed between the rows of server cabinets, the space is small, so the installation of the filter is limited by the space, the installation place is small, and it is not easy to install. Moreover, since the width of the unit is relatively small, door locks, display screens and other devices need to be installed on the door panels, the area of air inlet and outlet of the unit is relatively small, and the cooling capacity of the unit is also affected by the air inlet and outlet area and is difficult to increase. Therefore, in order to solve the problem that the filter installation space is small and difficult to install, the present invention proposes a side-outlet and side-return inter-row computer room air conditioner with easy installation of the filter. The filter is installed on the outside of the unit, the installation space is sufficient, and the structure is easy to install and disassemble. The air inlet and outlet of this type of air conditioner is side-inlet and side-outlet, and the air inlet and outlet area is also increased. Figure 2 shown.

[0115] The present invention is conceived as follows: the installation position of the unit filter and the air inlet and outlet mode are as follows: Figure 2 , 2-1 As shown in Figure 2-2, based on the traditional row-to-row machine room air conditioner, the present invention proposes a new filter installation position and installation structure, and installs the filter on the outside of the unit to solve the problem of insufficient installation space and difficulty in installing the filter in the row-to-row machine room air conditioner. At the same time, the honeycomb holes on the front and rear doors are eliminated, making the front and rear doors completely sealed, and honeycomb holes (or other processes such as blinds) are added to the front door columns, so that the wind can only be blown out from both sides, forming a side air inlet and side air outlet structure. Its specific frame structure is as follows Figure 3 As shown in the figure, the filter is installed on the outside of the unit, between the rear door pillar and the side panel.

[0116] In some embodiments,

[0117] The filtering structure 9 is a push-pull structure, which increases or decreases the size of the filtering area by pushing or pulling;

[0118] Alternatively, the filtering structure 9 is a foldable structure, so as to increase or decrease the size of the filtering area by folding, contracting or unfolding;

[0119] Alternatively, the filtering structure 9 is an elastic structure, so as to increase or decrease the size of the filtering area by elastic compression or elastic stretching.

[0120] These are several preferred structural forms of the filtering structure of the present invention, which can control the size of its filtering area according to the size of the actual working conditions, so as to filter the gas at the air inlet and improve the energy efficiency of the in-row air conditioner; it can be a push-pull structure, and the filtering area can be increased or decreased by pushing and pulling, or it can be a folding structure to increase or decrease the filtering area by folding and shrinking or unfolding, or it can be an elastic structure to increase or decrease the filtering area by elastic compression or elastic stretching.

[0121] In some embodiments,

[0122] When the air inlet 5 is arranged on the first side plate 3, or when the air inlet 5 and the first side plate 3 are on the same side and in contact, the first side plate 3 is a double-layer plate structure and can increase or decrease the size of the air inlet 5 by pushing and pulling; the filtering structure 9 is also a double-layer stacked push-pull structure to increase or decrease the size of the filtering area by pushing and pulling; the first side plate 3 can adjust the size of the air inlet 5 according to the actual required air intake volume; the filtering structure 9 is a filter screen.

[0123] This is the preferred structural form of the present invention. The preferred first side plate of the present invention is a double-layer plate structure, and the area of the air inlet is increased or decreased by pushing and pulling. The matching filtering structure is also a double-layer stacked push-pull structure, which is adapted to the air inlet formed by the double-layer plate structure of the first side plate to increase or decrease the filtering area by pushing and pulling, so as to be able to adjust the area of the air inlet and the area of the filtering structure according to the size of the actual working conditions, so as to ensure sufficient cooling of the server cabinet while reducing energy consumption, thereby improving the overall energy efficiency of the air conditioner.

[0124] The filter screen of the present invention is preferably a double-layer structure, and the filter screen can be pushed and pulled according to the actual required air intake area, so as to realize the change of the air intake area. As Figures 4-1 to 4-5 shown in the cross-sectional view of the side plate, the side plate is also a double-layer structure. When adjusting the filter screen, the side plate needs to be adjusted together to ensure that there is no gap between the filter screen and the side plate, so that air can only enter the unit through the filter screen. As Figure 2 、 2-1As shown in Figures 2-2, it is a schematic diagram of the unit after adjusting the air inlet area. The advantages of this structure are as follows: 1. The filter screen is installed on the outside of the unit, with sufficient installation space, which is more conducive to the installation and disassembly of the filter screen; 2. The filter screen fixing bracket is fixed with bolts, which can avoid thread stripping caused by frequent replacement of the filter screen; 3. One end of the filter screen is limited and the other end is fixed. The fixed position is at the middle cross beam of the unit and is fixed with a small bracket. The structure is simple, the position is appropriate, which is convenient for installation and disassembly of the bracket when replacing the filter screen; 4. The filter screen and the side plate are of double-sided structure, and the filter screen and the side plate can be adjusted according to actual needs to meet different air inlet volume requirements. The air outlet is on the front door column, and the column sheet metal is hollowed out (honeycomb holes, louvers, rectangular holes are all acceptable and can be punched according to actual needs). The front door column is located on both sides of the fan cavity, and the fan blows the air out from both side columns. According to the actual required air outlet area, the size of the column can be adjusted to meet different air outlet volume requirements.

[0125] In some embodiments,

[0126] When the air inlet 5 is provided on the first side plate 3, or when the air inlet 5 and the first side plate 3 are on the same side and are connected, the first side plate 3 is divided into two upper and lower split side plates, and the two upper and lower split side plates are connected by an intermediate cross beam 10. The air inlet 5 is also divided into a first air inlet provided on or connected to the upper side plate and a second air inlet provided on or connected to the lower side plate. The filtering structure 9 is also divided into two upper and lower split filter screens. The split filter screen on the upper side is arranged opposite to the first air inlet and can change with the size of the first air inlet. The split filter screen on the lower side is arranged opposite to the second air inlet and can change with the size of the second air inlet.

[0127] This is a further preferred structural form of the first side plate of the present invention, that is, a split side plate structure is formed in the upper and lower two parts, which are connected by an intermediate cross beam. The filtering structure is also divided into two upper and lower split filter screen structures. The upper split filter screen is arranged in cooperation with the upper first air inlet, and the lower split filter screen is arranged in cooperation with the lower second air inlet, forming a structure of an upper and lower split overall system, and can control the change of the air inlet and the filtering area according to the actual working conditions, so as to ensure effective cooling of the server cabinet while reducing power consumption and improving system energy efficiency.

[0128] In some embodiments,

[0129] When the in-row computer room air conditioner further includes a top plate 7 and a base 8, the in-row computer room air conditioner further includes a first bracket 11, a second bracket 12, a third bracket 13, and a fourth bracket 14. The first bracket 11 can fix the upper end of the upper split filter screen to the top plate 7, the second bracket 12 can fix the lower end of the upper split filter screen to the middle cross beam 10, the third bracket 13 can fix the upper end of the lower split filter screen to the middle cross beam 10, and the fourth bracket 14 can fix the lower end of the lower split filter screen to the base 8.

[0130] This is the preferred installation and fixing method for the side plate and filter screen of the split structure of the present invention. That is, the first bracket is used to fix the upper end of the upper split filter screen to the top plate, the second bracket is used to fix the lower end of the upper split filter screen to the middle cross beam, the third bracket is used to fix the upper end of the lower split filter screen to the middle cross beam, and the fourth bracket is used to fix the lower end of the lower split filter screen to the base, so as to effectively connect and fix the upper and lower split filter screens, and ensure the effective filtering effect at the air inlet.

[0131] In some embodiments,

[0132] The structures of the first bracket 11, the second bracket 12, and the third bracket 13 are all Z-shaped sheet metal parts; the structure of the fourth bracket 14 is a U-shaped sheet metal part. This is the preferred structural form of the first bracket, the second bracket, the third bracket, and the fourth bracket of the present invention, which can achieve the effect of fixing the filter screen to the top plate, the middle cross beam, and the base. The upper and lower split structural forms are set to support the structural strength of the middle part through the middle cross beam, avoiding the situation of poor structural strength, instability, or vibration at the middle position due to the side plate being set as a whole vertical plate with too long vertical length.

[0133] The specific installation method of the filter screen of the present invention is as Figures 4-1 to 4-5As shown in the figure. Four brackets four 14 are installed on the unit base, with 2 on each side (the quantity is not fixed and can be adjusted according to the size of the filter screen used, so as to adjust the quantity and size of the sheet metal). The bracket four 14 is a U-shaped sheet metal (or "concave" shape), and the lower end of the lower filter screen is clamped between the U-shaped sheet metals to achieve fixation. The bracket three 13 is a Z-shaped sheet metal, which tightly presses the upper end of the lower filter screen on the middle cross beam of the unit, and then is fixed with bolts. Four brackets one 11 are installed at the top cover of the unit, with 2 on each side (the quantity is not fixed and can be adjusted according to the size of the filter screen used, so as to adjust the quantity and size of the sheet metal). This sheet metal is a Z-shaped structure, and one end of the Z-shaped sheet metal is connected to the hem of the top cover to form a "concave" card slot. The upper end of the upper filter screen is clamped in this "concave" card slot, and the lower end is pressed on the middle cross beam of the unit by the bracket two 12. The bracket two 12 is fixed on the middle cross beam with bolts, so as to achieve the fixation of the filter screen. The structure of the filter screen fixing bracket is not unique and can be appropriately changed according to actual needs.

[0134] The internal layout of the unit of the present invention is as Figure 5-6 shown. To avoid affecting the air intake of the unit, the electrical box 18 needs to maintain a certain distance from the filter screen. In the present invention, the electrical box is placed obliquely, so that the electrical box forms a certain angle with the filter screen, increasing the distance between the electrical box and the filter screen and the side plate, thus avoiding affecting the air intake on both sides of the unit (for traditional row-by-row computer room air conditioners with front and rear air intake and exhaust, the electrical box is generally placed parallel to and close to the side plate to avoid affecting the air volume of the front and rear air intake). Since the width of the row-by-row computer room air conditioner is small and the internal space of the unit is limited, the evaporator is placed in an inclined manner. The unit air duct is as Figure 5 shown in the top view in the figure. Air enters the unit interior through the filter screens on both sides of the unit, and the filtered air flows inside the unit along the Figure 5 direction indicated by the arrow in the figure. After being cooled by the evaporator, it enters the cold air cavity. The fan rotates, sucks the air in the cold air cavity into the fan cavity, and then sends the cooled air out from both sides, thus achieving refrigeration. Since the areas on both sides of the row-by-row computer room air conditioner are much larger than the areas of the front and rear, and both the left and right sides can intake and exhaust air, the air intake and exhaust method of side air outlet and side air return makes the air intake and exhaust area much larger than that of traditional row-by-row computer room air conditioners, greatly improving the refrigeration efficiency. According to actual needs, the sizes of the air intake and exhaust ports can also be appropriately adjusted (as Figure 2 shown), so as to adjust the air intake and exhaust volume to meet the required refrigeration capacity. Moreover, since the row-by-row computer room air conditioner is installed between the server cabinets, the air outlet method of side air outlet can directly blow on the cabinets, and can cool the cabinets more efficiently.

[0135] After comparing the experimental data, when the length and width of the unit are the same, the cooling capacity of the present invention is higher than that of the traditional row-to-row computer room air conditioner (front and rear inlet and outlet air) with a height of 20 cm higher. The experimental data of the unit are compared as follows: the unit is powered at the rated voltage under the conditions of an inner ring temperature of 35 / 21°C and an outer ring temperature of 35 / -°C, turned on in cooling mode, set the compressor frequency to 64Hz, the number of electronic expansion valve steps to 196B, the external fan speed to 100%, the outlet air static pressure to 10Pa, and runs stably for 1h. The actual cooling capacity of the unit of the present invention is 24.216kW, and the actual cooling capacity of the front and rear inlet and outlet air unit is 23.819kW. The cooling capacity of the unit of the present invention is greater than that of the traditional front and rear inlet and outlet air unit. Moreover, during the installation and bench testing process, it is indeed more convenient to install and remove the filter when the filter is installed on the outside of the unit. In this experiment, the filter of the unit is relatively small (that is, the air inlet area is relatively small). Figure 4-1 and 4-2 As shown, the size of the filter is increased to increase the air intake area, thereby improving the cooling efficiency. It can be concluded that the side-outlet and side-return air-in-row computer room air conditioner with an easy-to-install filter proposed by the present invention is more convenient to install and disassemble than the traditional row-in-row computer room air conditioner, and the air intake area is relatively larger, and the cooling efficiency is higher.

[0136] The present invention is applicable to most inter-row machine room air conditioners. Through the invented filter installation structure, the filter is installed on the outside of the unit, thereby solving the problem of insufficient installation space and difficulty in installation of the filter. The filter is fixed to the outside of the unit by a few simple small brackets, with low installation cost and convenient installation and replacement, which not only reduces the cost, but also improves the assembly efficiency and facilitates after-sales maintenance of the filter. At the same time, through the new filter installation structure, the change of air inlet and outlet mode is realized, making the air inlet area larger (and the filter size can be adjusted according to the actual required air inlet area), and improving the cooling efficiency.

Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention. These improvements and variations should also be regarded as the protection scope of the present invention.
