[0002] Because the equipment in the computer room generates a lot of heat, special heat dissipation equipment is needed to maintain the temperature inside the computer room. The common practice is to use comfort air conditioning to run continuously to remove the heat from the room. Although this heat dissipation method can meet the requirements of heat dissipation and temperature control, it consumes a lot of energy and results in high operating costs. In transitional seasons (such as spring and autumn) or in low-temperature areas, air conditioning still cannot effectively utilize natural cold sources, resulting in energy waste. Utility Model Content

Through a heat pipe and dual-duct structure, outdoor cold air is introduced into the heat exchange shell to exchange heat with indoor hot air. The controller is electrically connected to indoor and outdoor temperature sensors, a first fan, and a second fan, enabling real-time acquisition of indoor and outdoor temperature information and automatic adjustment of fan operation based on preset temperature thresholds.

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] This utility model discloses a fresh air energy-saving system for a communication equipment room. The system mainly includes a heat exchange housing 1, a first air duct 2, a diverter plate 3, a second air duct 4, a heat pipe 5, a first filter 6, a first fan 7, a second filter 8, a second fan 9, an indoor temperature sensor 10, an outdoor temperature sensor 11, and a controller 12. The heat exchange housing 1 is installed on the side wall of the equipment room 13. One end of the first air duct 2 is connected to the heat exchange housing 1, and the other end is installed on the side wall of the equipment room 13, connecting the heat exchange housing 1 to the interior of the equipment room 13. The second air duct 4 is installed at the top of the heat exchange housing 1, connecting it to the outside air. The heat exchange housing 1 has a rectangular box structure, and the diverter plate 3 is installed inside the heat exchange housing 1. The interior of the exchange housing 1 is divided into two independent chambers by a diversion plate 3. The lower chamber is connected to the first air duct 2, and the upper chamber is connected to the second air duct 4. Both the upper and lower chambers are provided with air outlets 14 on their sides. Multiple heat pipes 5 pass through the diversion plate 3 and are evenly distributed. The two ends of the heat pipes 5 extend into the upper and lower chambers, respectively. The first filter 6 and the first fan 7 are installed inside the first air duct 2. The second filter 8 and the second fan 9 are installed inside the second air duct 4. The indoor temperature sensor 10 is installed inside the machine room 13, and the outdoor temperature sensor 11 is installed outside the machine room 13. The controller 12 is installed on the side wall outside the machine room 13. The first fan 7, the second fan 9, the indoor temperature sensor 10, the outdoor temperature sensor 11 and the controller 12 are electrically connected.

[0020] like Figure 5 , Figure 6 , Figure 7 As shown, the heat pipe 5 adopts a gravity heat pipe structure. The evaporation section of the heat pipe 5 is located in the lower chamber, and the condensation section is located in the upper chamber. The heat pipe 5 is filled with a phase change working fluid. When hot air in the machine room 13 enters the lower chamber, the evaporation section of the heat pipe 5 absorbs heat, the working fluid evaporates into a gaseous state and flows upward to the condensation section. After releasing heat in the condensation section, it turns back into a liquid state and flows back to the evaporation section. This cycle repeats, achieving efficient heat exchange.

[0021] like Figure 5 , Figure 6 , Figure 7 As shown, the outer wall of the heat pipe 5 is provided with annular fins 51 to increase the heat exchange area; the fins 51 significantly improve the heat transfer efficiency by increasing the heat exchange area, making the heat exchange more rapid and complete.

[0022] like Figure 5 , Figure 6 As shown, the diverter plate 3 is configured as a wave-shaped structure that increases the contact area between the heat pipe and the air and improves the heat exchange efficiency; it increases the contact area and time between the air and the heat pipe 5, which is beneficial to improving the heat exchange efficiency and further optimizing the airflow path and heat exchange effect.

[0023] The indoor temperature sensor 10 includes at least three sets, which are respectively installed at the top, middle and near the heat dissipation vents of the equipment in the computer room 13; it can comprehensively and accurately reflect the temperature conditions at different locations in the computer room 13.

[0024] Work process:

[0025] Indoor temperature sensor 10 collects real-time temperature data inside the computer room 13, while outdoor temperature sensor 11 collects ambient temperature data outside the computer room 1. The collected temperature data is transmitted to controller 12. Controller 12 receives the signals and analyzes and compares them. Based on the comparison results, controller 12 determines whether the fresh air energy-saving system needs to be activated for heat exchange. If controller 12 determines that the system needs to be activated, the first fan 7 and the second fan 9 begin operation. The first fan 7 operates, allowing hot air from inside the computer room 13 to enter the heat exchange housing 1 through the first air duct 2. Before entering the lower chamber, hot air passes through the first filter 6. The first filter 6 filters the air entering the heat exchange shell 1 from inside the machine room 13, preventing dust and other impurities in the machine room 13 from affecting the heat exchange efficiency of the heat pipe 5 and the normal operation of the system. The second fan 9 operates, drawing outdoor cold air into the upper chamber of the heat exchange shell 1 through the second air duct 4. Similarly, the cold air passes through the second filter 8 before entering the upper chamber. The second filter 8 filters the outdoor air entering the heat exchange shell 1, blocking outdoor dust, pollen, particulate matter, and other pollutants. Pollutants enter the heat exchange shell 1, ensuring the cleanliness of the air inside. The hot air entering the lower chamber comes into contact with the evaporation section of the heat pipe 5. Since the heat pipe 5 is filled with a phase change working fluid, the heat from the hot air causes the phase change working fluid to absorb heat in the evaporation section and evaporate into a gaseous state. The gaseous phase change working fluid rises along the heat pipe 5 to the condensation section, where it exchanges heat with the cold air in the upper chamber, releases heat, and then condenses back into a liquid state. The liquid phase change working fluid flows back to the evaporation section due to gravity. This cycle repeats, realizing the process of transferring heat from the indoor hot air to the outdoor cold air. During this process, the annular fins 51 on the outer wall of the heat pipe 5 increase the contact area between the heat pipe and the air, improving the heat exchange efficiency. The flow divider 3 is set with a wave-shaped structure, which further increases the contact area between the heat pipe and the air, also helping to improve the heat exchange efficiency. After heat exchange, the air temperature in the upper chamber rises and is discharged to the outside through the air outlet 14 on the side of the upper chamber. The air temperature in the lower chamber decreases and is discharged to the outside through the air outlet 14 on the side of the lower chamber. The indoor temperature sensor 10 and the outdoor temperature sensor 11 continuously collect temperature data and transmit it to the controller 12. The controller 12 dynamically adjusts the speed of the first fan 7 and the second fan 9 according to the real-time temperature data to ensure that the temperature in the machine room 13 is always maintained within a suitable range. If the indoor and outdoor temperature difference decreases, the controller 12 reduces the fan speed; if the temperature difference increases, the controller 12 increases the fan speed to enhance the heat exchange effect.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
