[0064] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0065] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.
[0066] In the existing technology, during the charging, discharging, capacity testing and self-discharge processes of the battery, the ambient temperature needs to be maintained at 25℃±3℃ through a cooling air conditioning system; while during the high-temperature immersion and high-temperature aging processes of the battery, the ambient temperature needs to be maintained at 50℃±5℃ and 65℃±5℃ respectively through a heating air conditioning system.
[0067] The refrigeration and air conditioning system cools the production environment by exchanging heat between chilled water and the air, and then discharges the waste heat generated during the heat exchange to the outside through a cooling tower. However, the system uses steam or electricity to heat the air in the production environment, resulting in significant energy consumption required to maintain both low and high temperatures simultaneously.
[0068] To overcome the deficiencies in the prior art, the air handling system provided in this application includes a cold air handling unit, a hot air handling unit, and a heat exchange unit. The cold air handling unit and the hot air handling unit are respectively disposed in a first space and a second space. The heat exchange unit is disposed on the cold air handling unit and the hot air handling unit. When the cold air handling unit processes and delivers the first airflow to the first space, the heat exchange unit can absorb heat from the first airflow to cool down the first airflow, thereby maintaining a low-temperature environment in the first space through the first airflow. At the same time, when the hot air handling unit processes and delivers the second airflow to the second space, the heat exchange unit releases the heat absorbed from the first airflow to the second airflow to heat up the second airflow, thereby maintaining a high-temperature environment in the second space through the second airflow. Therefore, compared to the existing technology which requires two separate air handling systems—a refrigeration air conditioning system and a heating air conditioning system—to maintain low-temperature and high-temperature environments respectively, resulting in higher overall energy consumption, this application can maintain both low-temperature and high-temperature environments simultaneously with just one air handling system. This consumes less energy than two separate air handling systems. Furthermore, at least part of the energy used to maintain the high-temperature environment in the second space comes from the energy generated when maintaining the low-temperature environment in the first space, allowing this portion of energy to be recovered and reused. This results in higher energy utilization and a reduction in overall energy consumption.
[0069] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.
[0070] Reference Figures 1 to 4 As shown, this application provides an air handling system, including:
[0071] A cold air handling unit 100 is provided in the first space 400 to deliver a first airflow to the first space 400.
[0072] Hot air processing unit 200 is provided in the second space 500 to deliver a second airflow into the second space 500.
[0073] Heat exchange unit 300, part of which is disposed in cold air handling unit 100 and the other part is disposed in hot air handling unit 200;
[0074] The heat exchange unit 300 is configured to absorb heat from the first airflow when the cold air handling unit 100 delivers the first airflow, and to release the heat absorbed from the first airflow to the second airflow when the hot air handling unit 200 delivers the second airflow.
[0075] It is understood that the cold air handling unit 100 is located in the first space 400 where a low temperature environment (25℃±3℃) needs to be maintained, and the hot air handling unit 200 is located in the second space 500 where a high temperature environment (50℃±5℃ or 65℃±5℃) needs to be maintained. The heat exchange unit 300 is partially located in the cold air handling unit 100 and the hot air handling unit 200 respectively, so as to connect the cold air handling unit 100 and the hot air handling unit 200.
[0076] When this air handling system is in operation, the cold air handling unit 100 can process the first airflow and deliver it to the first space 400. When the first airflow flows through the cold air handling unit 100, some of the heat exchange units 300 installed in the cold air handling unit 100 can absorb heat from the first airflow, thereby reducing the temperature of the first airflow. Then, by delivering the low-temperature first gas to the first space 400, the first space 400 is maintained in a low-temperature environment.
[0077] Meanwhile, the hot air processing unit 200 can process the second airflow and deliver it to the first space 400. The heat exchange unit 300 transfers the heat absorbed from the first airflow to the heat exchange units 300 located in the hot air processing unit 200. When the second airflow flows through the hot air processing unit 200, the heat exchange units 300 located in the hot air processing unit 200 can release heat to the second airflow, raising the temperature of the second airflow. Then, by delivering the high-temperature second gas to the second space 500, the second space 500 is maintained in a high-temperature environment.
[0078] The heat exchange unit 300 is partially installed in the cold air handling unit 100 to cool the first airflow instead of using conventional chilled water, and another part is installed in the hot air handling unit 200 to replace conventional steam or electric heating. It also realizes the secondary use of the heat generated by cooling the first airflow to heat the second airflow, achieving dual utilization of cold and hot airflows, with high energy utilization and low overall energy consumption.
[0079] The cold air treatment unit 100 processes the first airflow, and the hot air treatment unit 200 processes the second airflow. The processing here includes, but is not limited to, filtering the airflow to remove dust or floating matter mixed in the airflow and improve the cleanliness of the airflow. In addition, the airflow can be humidified or dried to adjust the moisture content of the airflow to meet the humidity requirements of the production environment. Alternatively, the flow rate and velocity of the airflow can be processed and adjusted. This application does not limit this.
[0080] Therefore, the air handling system provided in this application embodiment includes a cold air handling unit 100, a hot air handling unit 200, and a heat exchange unit 300. The cold air handling unit 100 and the hot air handling unit 200 are respectively disposed in the first space 400 and the second space 500. The heat exchange unit 300 is disposed on the cold air handling unit 100 and the hot air handling unit 200. When the cold air handling unit 100 processes and delivers the first airflow to the first space 400, the heat exchange unit 300 can absorb heat from the first airflow to cool down the first airflow and maintain a low temperature environment in the first space 400 through the first airflow. At the same time, when the hot air handling unit 200 processes and delivers the second airflow to the second space 500, the heat exchange unit 300 releases the heat absorbed from the first airflow to the second airflow to heat up the second airflow and maintain a high temperature environment in the second space 500 through the second airflow.
[0081] Compared to existing technologies that require two separate air handling systems—one for cooling and one for heating—to maintain low and high temperature environments respectively, resulting in higher overall energy consumption, this application achieves simultaneous maintenance of both low and high temperature environments with only one air handling system. This consumes less energy than two separate systems. Furthermore, the energy used to maintain the 500°C high temperature environment in the second space is at least partially derived from the energy generated when maintaining the 400°C low temperature environment in the first space, allowing this portion of energy to be recovered and reused. This results in higher energy utilization and a reduction in overall energy consumption.
[0082] Furthermore, it allows for greater integration of air conditioning equipment, a smaller footprint, and easier disassembly and maintenance.
[0083] Furthermore, it should be noted that, based on experimental verification, taking the maintenance of the first space 400 temperature at 25℃-28℃ and the second space 500 temperature at 45℃-50℃ throughout the year as an example, the air handling system provided in this application embodiment can achieve an annualized energy saving rate of over 50% compared to conventional refrigeration and heating air conditioning systems.
[0084] Reference Figures 1 to 4 As shown, in some embodiments, the heat exchange unit 300 includes:
[0085] Heat absorption element 310 is disposed in cold air processing unit 100 to absorb heat from the first airflow when the cold air processing unit 100 delivers the first airflow.
[0086] Heat-dissipating element 320 is disposed in hot air treatment unit 200 to release heat to the second airflow when the hot air treatment unit 200 delivers the second airflow;
[0087] The heat transfer element 330 connects the heat absorption element 310 and the heat release element 320 to transfer the heat absorbed by the heat absorption element 310 to the heat release element 320.
[0088] It is understandable that by configuring the heat absorber 310, heat releaser 320, and heat transferr 330, the heat transferr 330 can be used to achieve directional energy transfer between the heat absorber 310 and the heat releaser 320, thereby directionally transferring heat from the first airflow to the second airflow, thus achieving temperature regulation of the first and second airflows. Furthermore, the heat transfer process fully utilizes the heat absorbed by the heat absorber 310 during the cooling of the first airflow, avoiding heat waste, and allows the heat releaser 320 to use heat that might otherwise be wasted to heat the second airflow, improving the overall energy efficiency of the system.
[0089] The heat absorption temperature of the heat-absorbing element 310 can be set between 10°C and 20°C, while the heat release temperature of the heat-releasing element 320 can be set between 60°C and 80°C. The specific temperature can be determined according to the temperature requirements of the first space 400 and the second space 500, and this application does not impose any restrictions on this.
[0090] In practice, the heat-absorbing component 310 can be an evaporator, the heat-releasing component 320 can be a condenser, and the heat-transfer component 330 can be a compressor or other heat pump device.
[0091] Furthermore, refer to Figures 1 to 4 As shown, the heat exchange unit 300 also includes:
[0092] The connecting pipe 340 is used to fill the heat exchange medium. The heat absorption element 310 and the heat release element 320 are both connected to the heat transfer element 330 through the connecting pipe 340.
[0093] Control valve 350 is installed on connecting pipe 340 to control the flow rate of heat exchange medium in connecting pipe 340.
[0094] The heat exchange medium filled in the connecting pipe 340 serves as the carrier for heat transfer, effectively ensuring efficient heat transfer. Furthermore, the connecting pipe 340 can be arranged more freely, allowing for a more flexible arrangement of the positions of the heat absorber 310, heat transfer element 330, and heat release element 320. This enables the heat absorber 310 to be placed within the cold air handling unit 100 and the heat release element 320 within the hot air handling unit 200, avoiding problems caused by space constraints in heat transfer, optimizing the heat transfer path of the entire heat exchange unit 300, and improving heat transfer efficiency.
[0095] The control valve 350 can precisely control the flow rate of the heat exchange medium in the connecting pipe 340. When it is necessary to improve the heat exchange efficiency, the opening of the control valve 350 is increased, allowing more heat exchange medium to participate in the heat transfer process and accelerating the transfer of heat from the heat absorber 310 to the heat releaser 320. Conversely, when it is necessary to reduce the heat exchange efficiency, the opening of the control valve 350 is decreased, reducing the flow rate of the heat exchange medium.
[0096] In specific implementation, the heat exchange medium can be conventional refrigerants such as R410A, R32, R134a or R407C, or other unmentioned refrigerants, and the control valve 350 can be an electronic expansion valve, which is not limited in this application.
[0097] Among them, reference Figures 2 to 4 As shown, the connecting pipe 340 includes:
[0098] The first pipe 341 is connected in sequence to the outlet side of the heat absorption element 310, the heat transfer element 330, and the inlet side of the heat release element 320.
[0099] The second pipe 342 connects the outlet side of the heat-releasing element 320 and the inlet side of the heat-absorbing element 310, and the control valve 350 is installed on the second pipe 342.
[0100] It is understandable that the arrow on the connecting pipe 340 indicates the flow direction of the heat exchange medium inside the connecting pipe 340.
[0101] In this way, the connecting pipe 340 forms a closed loop between the heat-absorbing element 310, the heat-releasing element 320, and the heat-transfer element 330. The heat exchange medium continuously circulates in this loop, continuously absorbing heat from the first airflow at the heat-absorbing element 310, and then transferring it to the heat-releasing element 320 through the heat-transfer element 330, releasing heat to the second airflow. This achieves a continuous and stable heat exchange process, ensuring the continuous and efficient operation of the entire heat exchange unit 300.
[0102] Furthermore, the first pipe 341 and the second pipe 342 allow the heat exchange medium to flow in an orderly manner along the designed path. After absorbing heat from the heat absorber 310, the heat is transferred to the heat releaser 320 through the first pipe 341, and then returns to the heat absorber 310 through the second pipe 342, avoiding chaotic flow of the medium and improving the efficiency and stability of heat transfer.
[0103] In some embodiments, reference is made to Figure 4 As shown, the heat exchange unit 300 also includes:
[0104] Pressure detection element 360 is installed in the connecting pipe 340 to detect the pressure of the heat exchange medium in the connecting pipe 340;
[0105] Temperature sensing element 370 is installed in connecting pipe 340 to detect the temperature of the heat exchange medium inside connecting pipe 340.
[0106] Pressure detection element 360 and temperature detection element 370 are both installed on the first pipeline 341, and pressure detection element 360 and temperature detection element 370 can be installed between heat absorption element 310 and heat transfer element 330, and between heat transfer element 330 and heat release element 320.
[0107] The pressure sensor 360 can monitor the pressure of the heat exchange medium in the connecting pipe 340 in real time. When the pressure exceeds the normal range, it may indicate problems such as blockage in the connecting pipe 340, leakage of the heat exchange medium, or failure of other components in the system. The temperature sensor 370 can obtain the temperature information of the heat exchange medium in real time. If the temperature is too high, it may damage the performance of the heat exchange medium itself or cause thermal damage to the pipes and equipment; if the temperature is too low, the expected heat exchange effect may not be achieved.
[0108] Pressure sensors 360 and temperature sensors 370 are respectively installed between the heat absorber 310 and the heat transfer element 330, and between the heat transfer element 330 and the heat release element 320. This allows for segmented monitoring of the heat exchange process, and adjustment of operating parameters based on real-time pressure and temperature monitoring data. For example, if a segment's heat exchange efficiency is found to be low, optimization can be achieved by adjusting the flow rate of the control valve 350, or by adjusting the flow rate of the first or second airflow, thereby improving the overall performance of the entire heat exchange unit 300. Furthermore, when the heat exchange unit 300 malfunctions, the pressure and temperature monitoring data from different locations can help personnel quickly pinpoint the fault.
[0109] In addition, refer to Figure 2 As shown, the heat exchange unit 300 also includes a tube groove 380, which connects the cold air handling unit 100 and the hot air handling unit 200, and at least part of the connecting pipe 340 is disposed in the tube groove 380.
[0110] The duct groove 380 is specifically fixedly connected to the first housing 110 of the cold air handling unit 100 and the second housing 210 of the hot air handling unit 200, and the orientation of the duct groove 380 is consistent with that of the connecting pipe 340. By setting the duct groove 380, a physical protective barrier is provided for the connecting pipe 340, which can prevent the connecting pipe 340 from being impacted, squeezed, and scratched by external objects, reduce the risk of pipe damage and leakage caused by external forces, and extend the service life of the connecting pipe 340.
[0111] Furthermore, the tube groove 380 can provide a certain degree of insulation, reducing heat loss of the heat exchange medium in the connecting pipe 340 during the transmission process. Especially during the heat transfer process from the heat absorber 310 to the heat releaser 320, good insulation can enable more heat to be effectively transferred to the target location, improving the heat transfer efficiency of the entire heat exchange unit 300.
[0112] Furthermore, refer to Figure 2 As shown, a water receiving tray 381 is provided inside the pipe groove 380, and the water receiving tray 381 is correspondingly located below the heat absorption member 310.
[0113] During heat exchange, condensation may occur on the surface of the heat absorber 310 due to temperature changes, producing condensate. If the condensate drips directly onto other equipment, pipelines, or the ground below, it may cause corrosion, affecting the normal service life and performance of the equipment. The drip tray 381 can collect this condensate in a timely manner, preventing direct contact between the condensate and the equipment, thereby protecting other equipment inside the pipe groove 380 from condensate corrosion.
[0114] In some embodiments, refer to Figures 1 to 3 As shown, the cold air handling unit 100 includes:
[0115] The first housing 110 has a first air inlet cavity 111 and a first air outlet cavity 112 that communicate with each other. The first air inlet cavity 111 is used to communicate with at least one of the first space 400 and the outside world, and the first air outlet cavity 112 is used to communicate with the first space 400.
[0116] A cold air treatment assembly 120 is disposed in at least one of a first air inlet chamber 111 and a first air outlet chamber 112, so as to sequentially deliver filtered first airflow to the first space 400 through the first air inlet chamber 111 and the first air outlet chamber 112.
[0117] The heat-absorbing element 310 is disposed in the first air inlet cavity 111 or the first air outlet cavity 112.
[0118] It should be noted that the dashed arrows in the first space 400 indicate the direction of the first airflow, that is, the first airflow enters the first air inlet cavity 111 from the outside or the first space 400, flows from the first air inlet cavity 111 to the first air outlet cavity 112, and then flows into the first space 400 from the first air outlet cavity 112.
[0119] The first air inlet cavity 111 can communicate with at least one of the first space 400 and the outside, thereby allowing the cold air handling component 120 to draw air from the first space 400 for indoor air circulation and cooling, or to draw air from the outside to bring fresh air into the room, providing a flexible air intake method for the cold air handling unit 100. For example, when the air quality in the first space 400 is good but the temperature is high, only the air in the first space 400 can be introduced for processing to achieve internal air circulation and rapid cooling; when the outside air quality is good and the temperature is suitable, outside air can be introduced to improve the air quality in the first space 400; or air from both the first space 400 and the outside can be introduced simultaneously, flexibly adjusting the air intake ratio according to actual needs.
[0120] The first air outlet cavity 112 is connected to the first space 400, so that the first airflow entering the first housing 110 from the first space 400 can be processed and returned to the first space 400, forming a complete airflow delivery, which helps to quickly adjust the temperature and air quality in the first space 400, improve the cooling and air purification efficiency, and keep the environment in the first space 400 stable and comfortable.
[0121] The cold air handling assembly 120 is disposed in at least one of the first air inlet chamber 111 and the first air outlet chamber 112, and can at least filter the incoming first airflow, or can also regulate the humidity of the first airflow. When filtering, the cold air handling assembly 120 can remove impurities such as dust, pollen, smoke, and bacteria from the air, effectively improving the air quality in the first space 400, and reducing the adhesion of impurities on the surface of each device in the first housing 110, thus extending the service life of each device.
[0122] The heat absorber 310 is disposed in the first air inlet cavity 111 or the first air outlet cavity 112, and can fully exchange heat with the first airflow. When the heat absorber 310 is disposed in the first air inlet cavity 111, it can absorb heat from the air in the initial stage of the air entering the cold air treatment unit 100, reducing the air temperature and providing a better foundation for subsequent cold air treatment. When the heat absorber 310 is disposed in the first air outlet cavity 112, it can further cool and regulate the cold air to be delivered, ensuring that the temperature of the delivered cold air meets the requirements and improving the cooling effect. By setting the heat absorber 310 to work in conjunction with the cold air treatment component 120, the heat absorber 310 can achieve heat exchange more efficiently, transferring heat from the air to the heat exchange medium in the connecting pipe 340, thereby achieving the purpose of cooling.
[0123] In some embodiments, refer to Figure 2 and Figure 3 As shown, the cold air handling assembly 120 includes:
[0124] A cold air filter assembly 121 is disposed in at least one of the first air inlet chamber 111 and the first air outlet chamber 112 to filter the first airflow.
[0125] The first air supply assembly 122 is disposed in the first air outlet cavity 112 or the first air inlet cavity 111 to draw and deliver the first airflow.
[0126] The cold air filter assembly 121 is disposed in at least one of the first air inlet chamber 111 and the first air outlet chamber 112, and can filter the first airflow.
[0127] The first air supply component 122 is disposed in the first air outlet cavity 112 or the first air inlet cavity 111, and can provide power for the flow of the first airflow. When disposed in the first air inlet cavity 111, it can actively draw air from the first space 400 or the outside into the cold air treatment unit 100 to ensure that there is enough air to enter for processing; when disposed in the first air outlet cavity 112, it can quickly and efficiently deliver the processed cold air into the first space 400 to achieve effective air circulation.
[0128] Furthermore, refer to Figure 2 and Figure 3 As shown, the cold air filter assembly 121 includes:
[0129] The first cold air filter 1211 is disposed on the air inlet side of the first air inlet cavity 111.
[0130] The second cold air filter 1212 is disposed in the first air inlet cavity 111 and located between the first cold air filter 1211 and the first air outlet cavity 112, or the second cold air filter 1212 is disposed on the air outlet side of the first air outlet cavity 112.
[0131] The first cold air filter 1211 is located on the air inlet side of the first air inlet chamber 111. It can perform primary filtration on the incoming first airflow to intercept larger particulate impurities in the first airflow, such as dust, hair, and paper scraps, effectively protecting the subsequent second cold air filter 1212 and other equipment components.
[0132] The second cold air filter 1212 can be disposed within the first air inlet cavity 111 (located between the first cold air filter 1211 and the first air outlet cavity 112), or disposed on the air outlet side of the first air outlet cavity 112. Regardless of the arrangement, the second cold air filter 1212 is located on the downwind side of the first cold air filter 1211 to further refine the first airflow after its initial filtration by the first cold air filter 1211. The specific location of the second cold air filter 1212 can be flexibly adjusted according to the actual usage scenario and filtration requirements; this application does not impose any limitations on this. In this embodiment, the second cold air filter 1212 is specifically disposed on the air outlet side of the first air outlet cavity 112.
[0133] The first cold air filter element 1211 and the second cold air filter element 1212 can use different types of filter materials and filter technologies to form a combined filter and improve the filtration effect.
[0134] In some embodiments, refer to Figure 2 , Figure 3 and Figure 5 As shown, the first air supply assembly 122 includes a plurality of first air supply elements 1221 arranged in parallel. The first air supply elements 1221 are disposed in the first air outlet cavity 112 and located between the heat absorption element 310 and the first air inlet cavity 111.
[0135] The parallel operation of multiple first air supply components 1221 can significantly increase the total air volume and improve the air pressure to a certain extent. Furthermore, the parallel configuration of multiple first air supply components 1221 ensures that if one or more of the first air supply components 1221 fail, the others can continue to operate, thus guaranteeing the reliability and stability of the cold air handling unit 100.
[0136] In practice, the first air supply component 1221 is a volute-less electronically commutated fan.
[0137] The volute-less electronic commutator fan has poor high-temperature resistance and is suitable for low-temperature first space 400. It has high efficiency and can precisely adjust the speed according to actual needs.
[0138] The volute-less structure makes the first air supply component 1221 smaller and lighter, effectively saving installation space.
[0139] Furthermore, in some embodiments, reference is made to Figure 2 As shown, the heat transfer element 330 is disposed in the first air inlet cavity 111.
[0140] By placing the heat transfer element 330 inside the first air inlet cavity 111, the first airflow entering the first air inlet cavity 111 can cool the heat transfer element 330, avoiding the inability of the heat transfer element 330 to dissipate heat when placed in a closed space. At the same time, it improves the energy efficiency of the heat transfer element 330 and extends the service life of the heat exchange unit 300.
[0141] Furthermore, in some embodiments, reference is made to Figures 1 to 4 As shown, the hot air processing unit 200 includes:
[0142] The second housing 210 has a connected second air inlet cavity 211 and a second air outlet cavity 212, both of which are used to communicate with the second space 500.
[0143] Hot air processing assembly 220 is disposed in at least one of the second air inlet chamber 211 and the second air outlet chamber 212 to sequentially deliver filtered second airflow to the second space 500 through the second air inlet chamber 211 and the second air outlet chamber 212.
[0144] The heat dissipation element 320 is disposed in the second air inlet cavity 211 or the second air outlet cavity 212.
[0145] The overall structure and layout of the hot air handling unit 200 can be referenced from the cold air handling unit 100. The dashed arrows in the second space 500 indicate the direction of the second airflow, that is, the second airflow enters the second air inlet cavity 211 from the second space 500, flows from the second air inlet cavity 211 to the second air outlet cavity 212, and then flows into the second space 500 from the second air outlet cavity 212.
[0146] The second air inlet chamber 211 and the second air outlet chamber 212 are both connected to the second space 500, forming an air circulation channel to promote the circulation of air inside the second space 500, avoid air stagnation, and ensure a balanced temperature distribution.
[0147] The hot air handling assembly 220 is disposed in at least one of the second air inlet chamber 211 and the second air outlet chamber 212, and is capable of filtering the second airflow entering the second space 500 to improve the air quality of the second space 500.
[0148] Furthermore, refer to Figures 1 to 4 As shown, the hot air handling assembly 220 includes:
[0149] Hot air filter assembly 221 is disposed in at least one of the second air inlet chamber 211 and the second air outlet chamber 212 to filter the second airflow.
[0150] The second air supply component 222 is disposed in the second air inlet cavity 211 or the second air outlet cavity 212 to draw and deliver the second airflow.
[0151] The hot air filter assembly 221 is disposed in at least one of the second air inlet chamber 211 and the second air outlet chamber 212, and can filter the second airflow when it enters or exits the second space 500.
[0152] The second air supply component 222 is disposed within the second air inlet cavity 211 or the second air outlet cavity 212, and can generate a suction force to drive the second airflow to circulate between the second air inlet cavity 211, the second air outlet cavity 212, and the second space 500. It should be noted that, since the second space 500 is a high-temperature space and the temperature of the second airflow is high, the second air supply component 222 can be a high-temperature resistant fan other than a volute-less electronically commutated fan, to ensure stable operation of the second air supply component 222 in a high-temperature environment.
[0153] Furthermore, refer to Figures 2 to 4 As shown, the hot air filter assembly 221 includes:
[0154] The first hot air filter element 2211 is disposed on the air inlet side of the second air inlet cavity 211.
[0155] The second hot air filter 2212 is disposed in the second air inlet cavity 211 and located between the first hot air filter 2211 and the second air outlet cavity 212, or the second hot air filter 2212 is disposed on the air outlet side of the second air outlet cavity 212.
[0156] The first hot air filter 2211 is disposed on the air inlet side of the second air inlet cavity 211, and can perform preliminary filtration on the second airflow as soon as it enters the hot air processing unit 200. The second hot air filter 2212 further performs fine filtration on the air. In a specific implementation, the second hot air filter 2212 is disposed inside the second air inlet cavity 211 and located between the first hot air filter 2211 and the second air outlet cavity 212.
[0157] The first cold air filter 1211 and the first hot air filter 2211 can both be conventional pre-filters such as plate filters, pleated filters or automatic roll filters, while the second cold air filter 1212 and the second hot air filter 2212 can be conventional medium-efficiency filters such as bag filters or combination filters. This application does not limit the specific type of the above filter elements, and they can be selected according to the specific filtration requirements.
[0158] In some embodiments, refer to Figure 2 and Figure 3As shown, the second air supply component 222 is disposed in the second air inlet cavity 211 and is located between the heat dissipation component 320 and the second air outlet cavity 212.
[0159] When the second air supply component 222 is in operation, it accelerates the flow of the second airflow heated by the heat dissipation component 320. Since the second air supply component 222 is located between the heat dissipation component 320 and the second air outlet cavity 212, it allows the air to mix thoroughly in this area, resulting in a more uniform air temperature.
[0160] Furthermore, in some embodiments, reference is made to Figure 2 and Figure 3 As shown, the hot air treatment assembly 220 also includes an auxiliary heating element 223, which is disposed in the second air inlet chamber 211 and located between the heat dissipation element 320 and the second air outlet chamber 212.
[0161] It is understandable that when the heat provided by the heat-dissipating element 320 is insufficient, the auxiliary heating element 223 can be turned on to supplement the heating, ensuring that the temperature of the hot air delivered from the second air outlet 212 can meet the needs of different scenarios.
[0162] Furthermore, the auxiliary heating element 223 can reheat the air on top of the heating by the heat-releasing element 320, accelerating the temperature rise of the second airflow. Especially in the initial stage of system startup or when a rapid increase in hot air temperature is required, the auxiliary heating element 223 can quickly take effect, enabling the second airflow to reach the set temperature in a short time, thus improving the response speed and working efficiency of the entire hot air processing unit 200.
