DETAILED DESCRIPTION

[0025] See also Figures 1 to 3 The present invention provides an energy-saving device for a computer room air conditioner, comprising an air inlet cover 101, an exhaust cover 102, an air duct, a pressurizing mechanism and a pressurizing chamber 103, wherein the pressurizing chamber 103 is communicated with the air duct and is located on one side of the air duct, the exhaust cover 102 is arranged at one end of the air duct, and the exhaust cover 102 covers the air duct, the air inlet cover 101 is arranged at the other end of the air duct, and the air inlet cover 101 covers the air duct, and the number of the pressurizing mechanisms is multiple groups, and each group of the pressurizing mechanisms is respectively fixedly connected to the pressurizing chamber 103 and respectively embedded in the interior of the pressurizing chamber 103.

[0026] In this embodiment, the air duct is embedded in the wall, and the air inlet cover 101 is close to the ground, and the exhaust cover 102 is close to the roof. The air inlet cover 101 and the exhaust cover 102 are correspondingly installed at the two ends of the air duct. According to the measurement of the current indoor temperature and the calculation and judgment of the indoor heating and cooling rates, the number of the pressurizing mechanisms involved is controlled. The more the pressurizing mechanisms involved, the greater the flow rate and wind pressure of the circulating air, thereby improving the mixing efficiency of the indoor hot air and cold air. Multiple pressurizing mechanisms simultaneously apply pressure to the airflow, thereby increasing the wind pressure. When the wind pressure increases, the wind speed increases accordingly.

[0027] Furthermore, the pressurizing mechanism includes an installation bin 104, a telescopic electric cylinder 105, a pressurizing plate, a driving motor 106 and a fan propeller 107. The telescopic electric cylinder 105 is fixedly connected to the installation bin 104 and embedded in the interior of the installation bin 104. The pressurizing plate is fixedly connected to the output end of the telescopic electric cylinder 105 and is located on one side of the telescopic electric cylinder 105. The pressurizing plate is embedded in the inner side of the installation bin 104. The driving motor 106 is arranged on one side of the pressurizing plate, and the output end of the driving motor 106 passes through the pressurizing plate and is fixedly connected to the fan propeller 107.

[0028] In this embodiment, the telescopic electric cylinder 105 is installed and fixed by the mounting bin 104, and the pressure plate is embedded in the mounting bin 104, and the telescopic electric cylinder 105 drives the pressure plate to be telescopically regulated inside the mounting bin 104. When the pressure mechanism is engaged, the telescopic electric cylinder 105 is in an extended state, and the air duct is cut off by the pressure plate, and the drive motor 106 is started to drive the fan 107 to rotate, thereby pressurizing the air and increasing the air pressure and flow rate. When the pressure mechanism is not engaged, the telescopic electric cylinder 105 is in a contracted state, and the pressure plate completely closes the mounting bin 104 to prevent air turbulence in the air duct from affecting the flow of air.

[0029] Furthermore, the pressure plate includes a side panel 108, a mounting plate 109 and a connecting piece 110. The side panels 108 are provided in two groups.

The connecting piece 110 is fixedly connected to any one group of the side panels 108 and is located on one side of the side panels 108.

[0030] In this embodiment, the mounting plate 109 is used to install and fix the driving motor 106 and the fan propeller 107, the connecting member 110 is used to connect the output end of the telescopic electric cylinder 105, and the two sets of side panels 108 are used to close the mounting bin 104 when the telescopic electric cylinder 105 is extended and retracted to avoid air turbulence.

[0031] Furthermore, the pressure plate further includes a sealing rubber ring 111 . The sealing rubber ring 111 is provided in two groups. Each group of the sealing rubber rings 111 is fixedly connected to the corresponding side plate 108 and is located on one side of the corresponding side plate 108 .

[0032] In this embodiment, the sealing performance between the side panel 108 and the installation chamber 104 is improved by the sealing rubber ring 111, so as to prevent air from entering during flow and causing abnormal noise, so that the computer room air conditioning energy-saving device is quieter and more stable during operation.

[0033] Furthermore, the air duct includes an air inlet chamber 112, an air outlet chamber 113, a pressure regulating chamber 114 and a universal chamber 115. The number of the universal chambers 115 is two groups. The two groups of universal chambers 115 are respectively connected to the pressure regulating chamber 114 and are respectively located at the two ends of the pressure regulating chamber 114. The air outlet chamber 113 is connected to one group of the universal chambers 115, and the air inlet chamber 112 is connected to the other group of the universal chambers 115.

[0034] In this embodiment, the air inlet bin 112 and the air outlet bin 113 are used for air intake and air outlet respectively. At the same time, the angles of the air inlet bin 112 and the air outlet bin 113 can be adjusted through the two sets of universal bins 115 to achieve the desired installation angle. The pressure regulating bin 114 is the main air pressure regulating area.

[0035] Furthermore, the air duct also includes reinforcing fins 116 , and the number of the reinforcing fins 116 is multiple groups. Each group of the reinforcing fins 116 is fixedly connected to the pressure regulating chamber 114 and is respectively located on the outer wall of the pressure regulating chamber 114 .

[0036] In this embodiment, the reinforcing fins 116 can improve the stability of the embedded installation of the pressure regulating chamber 114, thereby ensuring the stability and reliability during operation.

[0037] Furthermore, the computer room air conditioning energy-saving device also includes a support adjustment mechanism, the number of the support adjustment mechanism is two groups, and the two groups of the support adjustment mechanism are respectively arranged on one side of the air duct.

[0038] In this embodiment, the support adjustment mechanism can adjust and fix the installation angles of the air inlet bin 112 and the air outlet bin 113, and can be installed and fixed in advance to avoid angle deviation during installation, thereby improving the installation stability of the computer room air conditioning energy-saving device.

[0039] Furthermore, each group of the support adjustment mechanism includes a support plate 117, a vertical plate 118 and a connecting plate 119, and the two ends of the vertical plate 118 are respectively arranged between the support rod and the connecting plate 119, and the two ends of the vertical plate 118 are respectively adapted to the corresponding support plate 117 and the connecting plate 119.

[0040] In this embodiment, the support plate 117 and the connecting plate 119 support and fix the vertical plate 118. The support plate 117 and the connecting plate 119 are fixed points. The two ends of the vertical plate 118 are respectively placed on the support plate 117 and the connecting plate 119 and are locked by nuts. In this way, the vertical plate 118 fixes the angle of the pressure regulating chamber 114 and the air inlet chamber 112 or the air outlet chamber 113. Different sizes of vertical plates 118 can be replaced for different installation angles to achieve fixed control of the installation angle.
