[0027] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Reference Figures 1 to 3 As shown, the utility model provides an air duct distribution structure, including a housing 10, an air duct 20, an air volume adjustment member 30 and a control member, wherein:

[0029] The air duct 20 is disposed within the housing 10 and includes a first end and a second end. The first end of the air duct 20 forms an air inlet 21 on the surface of the housing 10, and the second end of the air duct 20 forms at least two air outlets 22 on the surface of the housing 10. A fan is disposed within the air duct 20, and a control unit is connected to the fan signal to control the fan's wind speed. In the embodiment provided herein, the air inlet 21 is connected to the fan of the air duct distribution structure, and the fan delivers cooling air into the air duct 20 through the air inlet 21. The at least two air outlets 22 are respectively connected to different devices that need to be cooled. The air in the air duct 20 can be delivered to different devices through different air outlets 22 to achieve simultaneous cooling of multiple devices.

[0030] Since the air supply volume required by different equipment is different, in order to accurately meet the air volume required by different equipment, at least two air volume adjusting members 30 are set. The number of air volume adjusting members 30 is adapted to the number of air outlets 22. Each air outlet 22 is correspondingly provided with an air volume adjusting member 30. Each air volume adjusting member 30 is used to adjust the air volume of the corresponding air outlet 22, thereby achieving the cooling requirements of each equipment and accurately controlling the air volume of each air outlet 22.

[0031] At the same time, the present application also provides a control component, which is signal-connected to several air volume adjustment components 30 respectively. Each air volume adjustment component 30 is independently controlled by the control component. When air volume distribution is required, the control component is used to remotely control the air volume adjustment component 30 at the corresponding air outlet 22, which is conducive to realizing automatic control of the entire system, simple operation, and high distribution precision and accuracy.

[0032] The air duct distribution structure of the present application utilizes only one control component to precisely control the air volume of at least two air outlets 22, and can realize the distribution of any air volume of multiple air outlets 22. Compared with the temperature control equipment in the prior art, it has higher control accuracy and is conducive to reducing equipment costs. While meeting the air volume distribution and diversion, the temperature accuracy at the air outlet 22 can reach ±50mK.

[0033] In the embodiment provided herein, the air volume adjustment member 30 includes an adjustment portion 31 and an adjusted portion 32. The adjustment portion 31 is disposed within the air duct 20, and the adjusted portion 32 is disposed at the air outlet 22. Each adjustment portion 31 is used to adjust the corresponding adjusted portion 32, thereby controlling the air volume output from the corresponding air outlet 22. Different devices connected to the air outlet 22 require different air volumes, and the adjusted portion 32 can be controlled by the adjustment portion 31 at the air outlet 22 corresponding to the device, so that the air outlet 22 delivers the corresponding air volume.

[0034] In a feasible embodiment, referring to Figure 2 As shown, the regulated part 32 includes an air outlet valve port 321, and the regulating part 31 includes an air valve actuator 311. Each air outlet 22 is provided with an air outlet valve port 321, and each air outlet valve port 321 is correspondingly provided with an air valve actuator 311. Each air valve actuator 311 can control the opening and closing degree of the corresponding air outlet valve port 321, thereby realizing the control of the air outlet volume at the corresponding air outlet 22.

[0035] In order to further accurately control the air volume of each air outlet 22, in the embodiment provided in this application, refer to Figure 3 As shown, the air duct 20 includes a main air duct 23 and at least two secondary air ducts 24. One end of the at least two secondary air ducts 24 is connected to the main air duct 23, and the other end of each secondary air duct 24 is connected to an air outlet 22. The air volume adjustment member 30 at each air outlet 22 is provided in the corresponding secondary air duct 24. The air volume input by the main fan passes through the main air duct 23 and is respectively sent to each secondary air duct 24, and then sent out from the corresponding air outlet 22 in the secondary air duct 24. The air volume adjustment member 30 can adjust the opening and closing degree of the air outlet valve 321 in the corresponding secondary air duct 24 according to the air volume required by the equipment connected to the air outlet 22, so that the air volume of each air outlet 22 can be accurately controlled.

[0036] Preferably, the shell 10 has two air outlets 22, each air outlet 22 is connected to a device to be cooled, and the secondary air ducts 24 include two, and the two secondary air ducts 24 are respectively connected to one air outlet 22, and each secondary air duct 24 is provided with an air volume adjustment member 30 to distribute the air volume of the two devices. The distribution efficiency is high, and accurate distribution can be performed according to the equipment's demand for air volume; and the space inside the shell 10 can be reasonably utilized to set the main air duct 23 and the secondary air duct 24 to achieve a good distribution effect.

[0037] In other embodiments, the number of air outlets 22, secondary air ducts 24 and air volume adjustment members 30 can be set according to the overall structure of the shell 10, the internal space and the air volume required by each device connected to the air outlet 22, and is not limited here.

[0038] In order to achieve the desired cooling effect, in addition to controlling the air volume, the air temperature must also be controlled to achieve a precise cooling effect. Figure 2 As shown, a temperature sensor 40 is further provided at the second end of the air duct 20. The temperature sensor 40 can detect the outlet air temperature of the air outlet 22. When the cooling air flows through the air outlet 22, the temperature of the cooling air entering the device connected to the air outlet 22 can be detected in real time through the detection of the temperature sensor 40, and then it can be known whether the outlet air temperature meets the required cooling temperature. When the outlet air temperature does not meet the requirements, the air volume adjustment member 30 can be used to adjust the outlet air volume of the corresponding air outlet 22 so that the cooling air entering the device can reach the required outlet air temperature.

[0039] In the embodiment provided herein, the air volume adjustment member 30 includes an air outlet valve 321 and an air valve actuator 311. The air valve actuator 311 is used to control the opening and closing degree of the air outlet valve 321. Thus, the control member is used to remotely control the air valve actuator 311 to open and close the air outlet valve 321. When air volume distribution is required, the control member remotely controls the air valve actuator 311 of each air outlet 22 to operate independently, thereby facilitating automated control of the entire system, simplifying operation, and achieving high distribution precision and accuracy.

[0040] In a feasible implementation, the control component is the host computer software. The original software program code is edited on the host computer and instructions are sent to the lower part. The host computer instructions are then transmitted to the PLC board through the SNMP card, giving an AO signal. The opening of the air outlet valve 321 is adjusted by the output signal, thereby realizing remote automatic control of the host computer.

[0041] Under the premise that the air duct distribution structure is cooling normally, the overall safety of the air duct distribution structure must also be ensured. In the embodiment provided by the present application, a pressure sensor and a speed sensor are also provided at each air outlet 22. The pressure sensor and the speed sensor can detect the speed and pressure of the cooling air at the corresponding air outlet 22 in real time. When the pressure sensor and the speed sensor detect that the wind speed and the wind pressure at the air outlet 22 are too high, it may affect the overall safety performance of the air duct distribution structure. At this time, the speed of the main fan can be adjusted to reduce the wind speed or wind pressure at the air outlet 22 to improve the safety of the whole machine. When the pressure sensor and the speed sensor detect that the wind speed or wind pressure at the air outlet 22 is too low, the wind speed or wind pressure at the air outlet 22 can be appropriately increased to increase the air output of the air outlet 22 per unit time, thereby improving the cooling efficiency.

[0042] To precisely control the outlet temperature of air from the air outlet 22, a heating assembly is installed within the air duct 20. This assembly is used to adjust the outlet temperature of the air from the air outlet 22. Based on the temperature sensor's detection of the outlet temperature of the air outlet 22, if the outlet temperature is too low, the heating assembly heats the cooling air to bring the outlet temperature of the air outlet 22 up to the specified level. When the outlet temperature reaches or exceeds the specified level, the heating assembly is turned off to maintain the specified temperature.

[0043] Several embodiments are listed below to further illustrate the contents of the present invention. Those skilled in the art will appreciate that more air volume distribution methods can be designed based on the following embodiments, all of which fall within the scope of protection of the present invention.

[0044] Example 1

[0045] Two air outlets 22 are provided on the shell 10, and two air outlet valves 321 and air valve actuators 311 are configured at the ends of the air outlets 22. The air valve actuators 311 can be remotely controlled to control the air outlet valves 321 and adjust the air volume of the air outlets 22 on the left and right sides. At the same time, point tests were conducted and it was found that the performance was equally good.

[0046] Example 2

[0047] Using two fans corresponding to two different air outlets 22 on the same air duct distribution structure, the different air volumes of the two air outlets 22 can be controlled separately by adjusting the fan speed. The structure of the two fans makes it more stable and convenient to adjust the left and right air volumes.

[0048] Example 3

[0049] Two sets of air duct distribution structures are used and integrated into one complete machine to control the air outlets 22 of different air ducts 20 separately. When two sets of air duct distribution structures are used, stable air volume and accuracy requirements can be obtained at the end, but the equipment is relatively large and requires a higher cost.

[0050] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
