Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to air-cooled cooling devices and cooling equipment. Background Technology

[0002] During the cigarette production process, the continuous operation of various large-scale equipment generates a large amount of heat, which seriously affects production efficiency and product quality. Cooling equipment is used to cool down various large-scale equipment.

[0003] Currently, cooling equipment typically consists of multiple air-cooled cooling units. These units rely on a single air intake path to draw in outdoor air for heat dissipation. When the ambient temperature is too high, the high-temperature outdoor air cannot meet the demand for efficient heat dissipation, resulting in a significant decrease in cooling efficiency. This leads to significant fluctuations in indoor humidity, severely disrupting the stable temperature and humidity environment required for production, and consequently affecting product quality. The indoor temperature rise caused by the equipment operation forces the need to turn on the air conditioning system for cooling, significantly increasing energy costs. It is difficult to balance energy efficiency and stability while ensuring cooling performance.

[0004] Currently, there is an urgent need for air-cooled cooling devices and equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an air-cooled cooling device with multiple air inlet channels that can be flexibly switched to avoid the impact of high-temperature outdoor wind on cooling efficiency, stabilize indoor temperature and humidity, and balance cooling efficiency with energy-saving stability.

[0038] This embodiment discloses an air-cooled cooling device and cooling equipment, such as Figure 1As shown, the cooling device includes at least two air-cooled cooling units as described in this embodiment. The air-cooled cooling units in this embodiment are, for example... Figures 2-3 As shown, the air-cooled cooling device includes a first air inlet channel 11, a first air valve 21, a three-way connector, a second air inlet channel 12, a second air valve 22, a cooling mechanism 3, an air supply channel 13, and an exhaust channel 14. The first end of the first air inlet channel 11 can introduce outdoor air. The first air valve 21 is installed on the first air inlet channel 11 and can disconnect the first air inlet channel 11. The first end of the three-way connector is connected to the second end of the first air inlet channel 11. The first end of the second air inlet channel 12 can introduce indoor air. The second air valve 22 is installed on the second air inlet channel 12 and can disconnect the second air inlet channel 12. The second end of the three-way connector is connected to the second end of the second air inlet channel 12. The cooling mechanism 3 is used to reduce the temperature of the air. The two ends of the air supply channel 13 are respectively connected to the third end of the three-way connector and the input end of the cooling mechanism 3. The first end of the exhaust channel 14 is connected to the output end of the cooling mechanism 3, and the second end of the exhaust channel 14 can discharge air.

[0039] The air-cooled cooling device disclosed in this embodiment operates as follows: During the transitional seasons of spring, autumn, and winter, when the outdoor temperature is lower than the indoor temperature, outdoor air is introduced through the first air inlet channel 11, the first air valve 21 is opened, and the second air valve 22 is closed. The outdoor air is input into the cooling mechanism 3 through the first air inlet channel 11 and the air supply channel 13, and after being cooled by the cooling mechanism 3, it is output through the exhaust channel 14. During the non-transitional season of summer, when the outdoor temperature is higher than the indoor temperature, indoor air is introduced through the second air inlet channel 12, the first air valve 21 is closed, and the second air valve 22 is opened. The indoor air is input into the cooling mechanism 3 through the second air inlet channel 12 and the air supply channel 13, and after being cooled by the cooling mechanism 3, it is output through the exhaust channel 14. This air-cooled cooling device can flexibly switch the air inlet channel according to the season, making full use of natural cold sources and the low indoor temperature environment, avoiding the impact of high-temperature outdoor air on cooling efficiency, stabilizing indoor temperature and humidity, reducing the frequency of indoor air conditioning system operation, reducing energy consumption costs, and balancing high cooling efficiency with energy-saving and stable operation.

[0040] The cooling device disclosed in this embodiment adopts the above-mentioned air-cooled cooling device, which can switch the air intake according to the season, stabilize the indoor temperature and humidity, and has both high-efficiency cooling and energy saving.

[0041] like Figures 2-3As shown, the air-cooled cooling device also includes a fan 4, which is installed on the first air inlet channel 11. The fan 4 is used to draw outdoor air into the first air inlet channel 11. On the one hand, by installing the fan 4 on the first air inlet channel 11, the suction power of the outdoor air can be effectively improved. With the active air delivery of the fan 4, the problem of insufficient natural wind pressure can be compensated, ensuring that the low-temperature outdoor air in the transitional seasons of spring, autumn and winter is stably input into the cooling mechanism 3 through the first air inlet channel 11 and the air delivery channel 13, further improving the cooling effect, ensuring the stability of the indoor temperature and humidity environment, and enhancing the air circulation efficiency. On the other hand, relying on the controllable operation of the fan 4, the air intake volume can be flexibly adjusted according to the actual outdoor temperature, optimizing the utilization efficiency of the natural cold source.

[0042] It is worth noting that in this embodiment, seasons with ambient temperatures below 22 degrees Celsius are defined as transitional seasons, namely spring, autumn, and winter. Figure 2 The diagram shows the state of the air-cooled cooling device during the transitional season. Fan 4 is on, first air valve 21 is on, and second air valve 22 is closed. The season with an ambient temperature higher than or equal to 22 degrees Celsius is defined as the non-transitional season, i.e., summer. Figure 3 The image shows the state of the air-cooled cooling device during the transitional season. Fan 4 is in the off state, first air valve 21 is in the off state, and second air valve 22 is in the open state.

[0043] In this embodiment, the fan 4 is an explosion-proof silent fan. On the one hand, it meets the safety requirements for use in flammable and explosive environments. The explosion-proof design effectively avoids the danger caused by electrical sparks during operation, improving the safety and reliability of the air-cooled cooling device. On the other hand, the silent characteristics of the explosion-proof silent fan can reduce noise pollution during operation, creating a quieter working environment.

[0044] In this embodiment, both the first air valve 21 and the second air valve 22 are opposing multi-leaf air valves. On the one hand, the opposing multi-leaf air valves can precisely control the air intake by adjusting the blade angle. That is, the first air valve 21 can finely regulate the air intake during the transitional season, and the second air valve 22 can finely regulate the air intake during the non-transitional season. It can also achieve flexible switching between the air intake channels during the transitional and non-transitional seasons. On the other hand, the opposing multi-leaf structure has good sealing performance, which can effectively prevent outdoor air from entering the second air intake channel 12 from the first air intake channel 11, or indoor air from the second air intake channel 12 from entering the first air intake channel 11. This ensures that outdoor or indoor air is stably input into the cooling mechanism 3 according to a preset path, improving the reliability of the air-cooled cooling device.

[0045] like Figures 2-3As shown, a single-layer louvered air vent 121 is provided at the end of the second air intake channel 12, which allows for adjustable airflow in the second air intake channel 12. The airflow guiding effect of the single-layer louvered air vent 121 optimizes the intake efficiency of indoor air. The intake direction and airflow volume of the indoor air can be adjusted by the angle of the louvers of the single-layer louvered air vent 121, adapting to the needs of introducing indoor air in summer during non-transitional seasons. This ensures that the airflow enters the second air intake channel 12 evenly, ensuring a stable airflow to the cooling mechanism 3 via the air supply channel 13, enhancing the continuity and uniformity of the cooling process, and thus ensuring a constant indoor temperature and humidity environment. This improves the practicality of the device while supporting efficient cooling and energy-saving operation. At the same time, it prevents debris or large dust particles from entering the second air intake channel 12, improving the purity of the incoming air.

[0046] like Figures 2-3 As shown, the air-cooled cooling device also includes an air inlet protective louver 51 and an exhaust protective louver 52. The air inlet protective louver 51 is located at the first end of the first air inlet channel 11, and the exhaust protective louver 52 is located at the second end of the exhaust channel 14. The air inlet protective louver 51 can effectively block rainwater from entering the first air inlet channel 11, preventing damage to the internal components of the device due to rainwater intrusion, and improving the waterproof performance of the device in outdoor environments. At the same time, it does not affect the normal air circulation, ensuring that outdoor air is smoothly drawn into the first air inlet channel 11 through the air inlet protective louver 51 during the transition season. It can also reduce the entry of external debris and dust into the first air inlet channel 11, maintaining the cleanliness of the internal airflow. The exhaust louver 52 can effectively block water from entering the exhaust duct 14, preventing damage to the internal components of the device due to water intrusion, and improving the waterproof performance of the device in outdoor environments. During non-transitional seasons, the airflow cooled by the exhaust louver 52 is stably discharged, which can also reduce the entry of external debris and dust into the exhaust duct 14, maintain the cleanliness of the internal airflow, and enable the air-cooled cooling device to maintain efficient and stable cooling performance under different climatic conditions.

[0047] Specifically, in this embodiment, the installation process of the air inlet protective louver 51 is roughly as follows: the glass on the window is removed to form an installation opening; a hood is installed at the end of the installation opening facing indoors and connected to the first air inlet channel 11; the air inlet protective louver 51 is installed at the end of the installation opening facing outdoors. On the one hand, the air inlet protective louver 51 facing outdoors can allow outdoor air to flow in while blocking rainwater from entering, ensuring the smooth airflow and waterproofing of the external circulation air structure. The hood facing indoors, connected to the first air inlet channel 11, can guide outdoor air into the first air inlet channel 11, optimizing the airflow path and improving air circulation efficiency. On the other hand, by utilizing the existing window to modify the installation opening, there is no need to open an additional wall structure, reducing installation complexity and allowing the device to be tightly integrated with the building window structure, enhancing the overall rational use of space.

[0048] In this embodiment, the cooling mechanism 3 includes a heat exchanger for absorbing heat from outdoor or indoor air. By absorbing heat from the outdoor air introduced through the first air inlet channel 11 or the indoor air introduced through the second air inlet channel 12, the cooling mechanism 3 can cool the air and provide reliable temperature control.

[0049] like Figures 2-3 As shown, the first air intake channel 11 is formed by sequentially connecting a first air intake pipe 111, a main air duct 112, and branch air ducts 113. The first end of the first air intake pipe 111 can introduce outdoor air into the main air duct 112. The main air duct 112 can deliver outdoor air to multiple branch air ducts 113 connected to the main air duct 112. Each branch air duct 113 is equipped with a first air valve 21 and is connected to the air supply channel 13. On one hand, this graded duct structure can efficiently introduce outdoor air into the main air duct 112 and evenly distribute it to multiple branch air ducts 113, expanding the air intake coverage area and improving the delivery efficiency and uniformity of outdoor air. The connection between the branch air ducts 113 and the air supply channel 13 allows outdoor air to quickly and efficiently enter the cooling mechanism 3, enhancing the system response speed. On the other hand, the first air valve 21 on the branch air duct 113 can independently adjust the airflow of each branch, flexibly adapting to the cooling needs of different areas and avoiding insufficient local cooling or energy waste due to uneven airflow distribution.

[0050] like Figures 2-3 As shown, the main air duct 112 is equipped with six branch air ducts 113 connected to it. The air-cooled cooling device includes six T-joints, six second air inlet channels 12, six air supply channels 13, three cooling mechanisms 3, and three exhaust channels 14. The three ends of any T-joint are respectively connected to the branch air duct 113, the second air inlet channel 12, and the air supply channel 13 corresponding to its position. The two input ends of any one of the three cooling mechanisms 3 are respectively connected to the two adjacent air supply channels 13, and the three exhaust channels 14 are respectively connected to the output ends of the corresponding cooling mechanisms 3. An air-cooled cooling device includes three cooling mechanisms 3. The two input ends of each cooling mechanism 3 are respectively connected to the two adjacent air supply channels 13, and the three output ends of the three cooling mechanisms 3 are respectively connected to the three corresponding exhaust channels 14, ensuring that the outdoor air input to the cooling mechanisms 3 from the six branch air ducts 113 can be quickly cooled, and the cooled airflow can be quickly discharged, maintaining a stable air-cooling cycle.

[0051] like Figure 1As shown, the cooling equipment in this embodiment includes two air-cooled cooling devices, one of which has a main air duct 112 that can be connected in series with the other air-cooled cooling device's main air duct 112. This cooling equipment effectively expands the air intake coverage area and enhances the adaptability of the cooling system to different scales. This design not only improves the overall cooling capacity but also meets the temperature control requirements of larger spaces or higher loads.

[0052] In other embodiments, the number of air-cooled cooling devices in the cooling equipment can be three, four, five, etc., and no specific limitation is made here.

[0053] In this embodiment, the cooling equipment includes six cooling units 3, one of which has a circulating air volume of 1200 cubic meters per hour, and the other five cooling units 3 have a circulating air volume of 1000 cubic meters per hour. Every three cooling units 3 share one fan 4 to guide outdoor air into the first air intake channel 11. Each fan 4 has an air volume of 3500 cubic meters per hour and an air pressure of 80 Pa. The types of cooling units 3 and fans 4 are not specifically limited here.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
