Description

[0001] This application is a divisional application of Chinese patent application filed on May 10, 2024, with application number 202421001869.3, entitled "Air Guide Device and Thermal Management Unit". Technical Field

[0002] This application relates to the field of refrigeration and air conditioning technology, specifically to an air guide device and a thermal management unit including the air guide device. Background Technology

[0003] Due to space constraints, energy storage equipment such as energy storage containers and battery cabinets are often placed close together. This may result in air conditioners between adjacent rows of energy storage equipment being arranged side by side or facing each other. Energy storage air conditioners are generally door-mounted. During cooling operation, the condenser fan needs to exhaust hot air to the outside, usually horizontally. However, when energy storage containers are densely arranged or even facing each other, the condenser fans of each energy storage air conditioner blow air into each other and affect each other, which can cause short circuits in the air field and affect the operation of the thermal management unit. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the main objective of this application is to provide an air guiding device and a thermal management unit.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A thermal management unit, comprising:

[0007] The main body is provided with a first air outlet and an air inlet, with the air inlet located below the first air outlet;

[0008] An air guide plate is installed at the first air outlet. The air guide plate includes a frame, and the frame is connected to a plurality of arrayed louvers. The louvers have an upward tilt angle, and there are air guide holes between adjacent louvers.

[0009] The louvers and air guide holes in this embodiment allow the air discharged from the first air outlet of the thermal management unit to flow upwards, thereby reducing the risk of hot air discharged from the first air outlet being re-drawn in and affecting condensation. At the same time, the upward tilt of the louvers can also reduce the mutual airflow and interference between adjacent thermal management units, reduce the occurrence of airflow short circuits, and ensure the normal operation of the thermal management units.

[0010] Accordingly, this application also provides an air guiding device for an energy storage thermal management unit, comprising:

[0011] Air guide plate, the air guide plate having a frame;

[0012] Louvers, with multiple louvers arranged in an array and connected to the frame;

[0013] The louvers have an upward tilt angle, and there are air guide holes between adjacent louvers.

[0014] The upward-sloping louvers of this application allow the air discharged from the first air outlet of the thermal management unit to flow upward, thereby reducing the risk of hot air discharged from the first air outlet being re-inhaled and affecting condensation. They also reduce the mutual airflow and interference between adjacent thermal management units, reduce the occurrence of airflow short circuits, and ensure the normal operation of the thermal management units.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more, and the term "various types" refers to two or more; the terms "connection," "fixed," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0043] Energy storage battery containers and cabinets are generally placed in open outdoor areas far from city centers, where the climate is unpredictable, especially in areas with frequent sandstorms. The harsh weather conditions seriously affect the cooling effect and service life of air conditioners.

[0044] Currently, thermal management units on the market, such as air conditioning units, generally use external filter screens to cope with the above-mentioned weather conditions. However, this solution has the following drawbacks: firstly, it affects the appearance; secondly, it requires regular replacement, which is inconvenient to operate; and thirdly, due to site limitations, energy storage equipment such as energy storage containers and energy storage battery cabinets are often placed densely. This may result in air conditioners being arranged side by side or facing each other between adjacent rows of energy storage equipment, causing mutual airflow and interference between the air conditioners, which may lead to short circuits in the air field and affect the operation of the air conditioning units.

[0045] Reference Figures 1 to 3 As shown, an embodiment of this application discloses a thermal management unit, which includes a main body 200 and an air guiding device 100. The main body 200 includes a housing 201, a partition 202, a compressor 203, a condenser 204, an evaporator 205, an external fan 206, an internal fan 207, an electric heater 209, and an electrical control box 208. The partition 202 is disposed inside the housing 201 and connected to the inner wall of the housing 201 to divide the housing 201 into a first cavity and a second cavity. The housing 201 has a first air outlet 201a and a second air outlet (not shown in the figure). The first air outlet 201a is located in the first cavity, and the second air outlet is located in the second cavity. The compressor 203, the condenser 204, and the external fan 206 are respectively installed in the first cavity, and the evaporator 205 and the internal fan 207 are respectively installed in the second cavity, and the compressor 203, the condenser 204, and the evaporator 205 are connected in sequence. The electrical control box 208 is connected to the compressor 203, the outdoor fan 206, and the indoor fan 207 respectively, and is used to control the operation of the compressor 203, the outdoor fan 206, and the indoor fan 207. The air guide device 100 is mounted at the first air outlet 201a of the housing 201, and is used to guide the air discharged from the thermal management unit in a first direction, which intersects with the horizontal direction. In this embodiment, the air guide device 100 is used to guide the air discharged from the thermal management unit above the thermal management unit.

[0046] During refrigeration, the refrigerant is compressed into a high-temperature, high-pressure gaseous refrigerant by the compressor 203 and then enters the condenser 204. The gaseous refrigerant undergoes heat exchange in the condenser 204 and becomes a liquid refrigerant. After passing through the throttling element, it enters the evaporator 205. The refrigerant undergoes heat exchange in the evaporator 205 and becomes a gaseous refrigerant before entering the compressor 203. The indoor fan 207 is used to deliver the air with a lower temperature after heat exchange with the evaporator 205 to the room through the second air outlet. The outdoor fan 206 is used to deliver the air with a higher temperature after heat exchange with the condenser 204 to the outside through the first air outlet 201a.

[0047] Reference Figure 4 and Figure 5As shown, the air guiding device 100 includes an air guiding plate 101 and an air guiding structure 102 disposed on the air guiding plate 101. The air guiding plate 101 is installed at the first air outlet 201a, and the outer surface of the air guiding plate 101 is flush with the outer surface of the housing 201. The air guiding structure 102 includes a louvered plate 102b and an air guiding hole 102a. The air guiding hole 102a is opened in the air guiding plate 101. The louvered plate 102b is connected to the air guiding plate 101 and located on the outside of the air guiding plate 101. The louvered plate 102b is located at the air guiding hole 102a, so that the air discharged from the first air outlet 201a can be guided in a first direction through the cooperation of the louvered plate 102b and the air guiding hole 102a. In this embodiment, the outer surface of the air guiding plate 101 is flush with the outer surface of the housing 201, thereby maintaining the shape of the thermal management unit itself, resulting in a small size and lower air resistance.

[0048] Specifically, the position of the first air outlet 201a corresponds to the position of the condenser 204, and a flow channel 300 is provided between the air guide plate 101 and the condenser 204. An outlet 302 is provided at the lower part of the air guide plate 101, and the outlet 302 communicates with the flow channel 300. The height of the bottom wall of the flow channel 300 near the outlet 302 is lower than the height of the end away from the outlet 302. In this embodiment, through the arrangement of the flow channel 300 and the outlet 302, sand, dust, rainwater, etc., entering the main body 200 can be effectively diverted through the flow channel 300 to the outlet 302 and discharged from the outlet 302. This prevents rainwater from accumulating at the bottom of the air guide device and overflowing back into the thermal management unit, and also prevents sand particles from accumulating at the bottom of the air guide device and causing blockage of the unit. Meanwhile, the bottom wall of the diversion channel 300 is set such that the height of the end near the outlet 302 is lower than the height of the end away from the outlet 302, which is conducive to the smooth discharge of rainwater and dust and avoids the accumulation at the bottom that blocks the outlet.

[0049] In this embodiment, the louver 102b has its opening facing upwards, and the angle between the louver 102b and the air guide plate 101 is α, where α is an acute angle. For example, the angle α can be 30°, 45°, 60°, etc. In this embodiment, the air inlet of the first cavity is located below the first air outlet. In order to prevent the hot air discharged from the first air outlet from being sucked into the first cavity by the external fan from the air inlet and affecting the condensation process, the louver is set to face upwards. In other embodiments, it can also face other directions.

[0050] To prevent dust and impurities from entering the main body 200 and affecting the normal operation of the components inside the main body 200, the main body 200 also includes a filter plate 301. At least a portion of the filter plate 301 is disposed between the air guide plate 101 and the condenser 204. The condenser 204 can be installed on the filter plate 301 and connected to the periphery of the first air outlet 201a. It is a closed connection structure so as to prevent dust and impurities from entering the main body 200 through the filter plate 301.

[0051] The thermal management unit in this embodiment is equipped with two protective barriers. The air guide device 100 can serve as the first external air barrier, and the filter plate 301 can serve as the second barrier. The two barriers can resist dust and sand at the same time and achieve a filtering effect, which helps to extend the service life of the thermal management unit.

[0052] This application, without altering the external dimensions of the thermal management unit, utilizes a specially designed air guide device to change the airflow direction of the unit. This directs the hot air blown out by the thermal management unit to the upper or slightly above it, where airflow is better. This prevents the air outlets of two energy storage devices from blowing directly onto each other when they are densely placed, thus avoiding poor heat dissipation. It also prevents hot air blown horizontally from being re-inhaled into the air inlet of the thermal management unit, causing a short circuit in the airflow and affecting the cooling performance. Furthermore, the air guide device can form an air barrier on the outside of the thermal management unit, acting as a dust and sand filter, thereby extending the unit's lifespan.

[0053] Accordingly, embodiments of this application also disclose another thermal management assembly, referring to Figure 6 and Figure 7 As shown, the thermal management unit includes a main body 200 and an air guiding device 100. The main body 200 includes a shell, a partition, a compressor, a condenser, an evaporator, an outdoor fan, an indoor fan, an electric heater, and an electrical control box. The partition is disposed inside the shell and connected to the inner wall of the shell to divide the shell into a first cavity and a second cavity. The shell has a first air outlet and a second air outlet, with the first air outlet located in the first cavity and the second air outlet located in the second cavity. The compressor, condenser, and outdoor fan are respectively installed in the first cavity, and the evaporator and indoor fan are respectively installed in the second cavity, and the compressor, condenser, and evaporator are connected in sequence. The electrical control box is connected to the compressor, outdoor fan, and indoor fan respectively, and is used to control the operation of the compressor, outdoor fan, and indoor fan. The air guiding device 100 is assembled at the first air outlet of the main body 200 to guide the air discharged from the thermal management unit in a first direction, which intersects with the horizontal direction.

[0054] The outdoor fan is used to deliver the hot air, which has exchanged heat with the condenser, to the outside through the first air outlet.

[0055] Reference Figure 8As shown, the air guiding device 100 includes an air guiding plate 101, a connecting plate 2, a first air guiding structure 3, and a third air guiding structure 5. The connecting plate 2 is connected to both sides of the air guiding plate 101 to form an air guiding channel. The air guiding plate 101 has a first air guiding part 11 and a second air guiding part 12. The first air guiding part 11 and the second air guiding part 12 are integrally formed or fixedly connected, and a preset included angle θ is provided between the second air guiding part 12 and the first air guiding part 11. The included angle θ is an obtuse angle, and the included angle θ can be 100°, 120°, 150°, etc. The first air guiding structure 3 is disposed on the first air guiding part 11 and is used to guide the air discharged from the main body 200 in a first direction. The third air guiding structure 5 is disposed on the second air guiding part 12 and is used to guide the air discharged from the main body 200 in a second direction. The second direction intersects with the horizontal direction, and the second direction and the first direction can be the same direction.

[0056] In this embodiment, the connection plate 2 is provided to prevent hot air discharged from the thermal management unit from being blown out from the side of the air guide device, thus preventing short circuit in the air field. At the same time, by providing the first air guide structure 3 and the third air guide structure 5, a portion of the hot air can be discharged through the first air guide structure 3, while a portion of the hot air continues to move upward and is discharged through the third air guide structure 5, which can effectively increase the air outlet area and improve the heat dissipation efficiency.

[0057] In this embodiment, the first air guide 11 and the second air guide 12 are integrally formed or fixedly connected, and the included angle θ between the second air guide 12 and the first air guide 11 is an obtuse angle. It can be understood that in other embodiments, the included angle θ between the second air guide 12 and the first air guide 11 can also be a right angle, as shown in the reference... Figures 18 to 20 As shown.

[0058] Reference Figure 9 and Figure 10 As shown, the first air guiding structure 3 includes a first louver 32 and a first air guiding hole 31. The first air guiding hole 31 is opened in the first air guiding section 11. The first louver 32 is connected to the air guiding plate 101 and is located on the outside of the air guiding plate 101. The first louver 32 is located at the first air guiding hole 31. The first louver 32 and the first air guiding hole 31 can guide the air discharged from the main body 200 in a first direction. The third air guiding structure 5 is a third air guiding hole 51, which is opened in the first air guiding section 11.

[0059] In this embodiment, the angle between the first louver 32 and the first air guide 11 is α, and the angle α is an acute angle. For example, the angle α can be 30°, 45°, 60°, etc. (Refer to...) Figure 11 As shown.

[0060] Continue to refer to Figure 8As shown, to facilitate the discharge of rainwater, sand, etc., the lower part of the air guide device 100 is also provided with an outlet 302, through which rainwater, sand, etc. can be discharged. In this embodiment, the bottom of the air guide device 100 is set to a completely open state, thereby preventing rainwater from accumulating at the bottom of the air guide device and overflowing into the thermal management unit, and also preventing wind and sand particles from accumulating at the bottom of the air guide device and causing the unit to become dirty and clogged.

[0061] This application employs a special design for the air guide device to alter the airflow direction of the thermal management unit, thereby preventing short circuits in the airflow field. Furthermore, the air guide device also serves to prevent dust and sand, by adding a protective barrier to one side of the thermal management unit to filter a certain amount of dust and sand, which helps improve the efficiency of the thermal management unit and extend its service life.

[0062] Based on the above embodiments, this application also discloses another specific implementation method, referring to... Figure 12 and Figure 13 As shown, in this embodiment, the air guiding device 100 further includes a second air guiding structure 4. The first air guiding section 11 has a first region 111 and a second region 112. The second region 112 is located on the first side of the first region 111, and the second air guiding section 12 is located on the second side of the first region 111. The first air guiding structure 3 is disposed in the first region 111, and the second air guiding structure 4 is disposed in the second region 112. The arrangement density of the second air guiding structure 4 is less than the arrangement density of the first air guiding structure 3, that is, the distance between two adjacent second air guiding structures 4 is greater than the distance between two adjacent first air guiding structures 3. The first air guiding structure 3 and the second air guiding structure 4 can guide the air discharged from the main body 200 in a first direction. A third air guiding structure 5 is disposed in the second air guiding section 12 so that the air discharged from the main body 200 can be guided in a second direction.

[0063] Continue to refer to Figure 12 As shown, the first air guide hole 31 is opened in the first region 111. The first louver 32 is connected to the air guide plate 101 and located outside the air guide plate 101, and the first louver 32 is located at the first air guide hole 31. The first louver 32 and the first air guide hole 31 can guide the air discharged from the main body 200 in the first direction. The second air guide structure 4 includes a second louver 42 and a second air guide hole 41. The second air guide hole 41 is opened in the second region 112. The second louver 42 is connected to the air guide plate 101 and located outside the air guide plate 101, and the second louver 42 is located at the second air guide hole 41. The second louver 42 and the second air guide hole 41 can guide the air discharged from the main body 200 in the first direction.

[0064] Reference Figure 14As shown, the angle between the second louver 42 and the first air guide 11 is β, and the angle β is an acute angle. For example, the angle β can be 30°, 45°, 60°, etc.

[0065] In this embodiment, the air guiding device is arranged in a dense upper and sparse lower air guiding structure, which can effectively increase the air guiding area and make the exhaust smoother.

[0066] Based on the above embodiments, this application also discloses another specific implementation method, referring to... Figure 15 and Figure 16 As shown, in this embodiment, the second air guiding structure 4 includes a guide plate 44 and a guide hole 43. The guide hole 43 is opened in the second region 112. The guide plate 44 is connected to the air guiding plate 101 and is located inside the air guiding plate 101. The guide plate 44 is located at the guide hole 43. The guide plate 44 and the guide hole 43 can guide the air discharged from the main body 200 to the first direction.

[0067] Reference Figure 17 As shown, the air guide plate 44 is set with its opening facing downwards, and the angle between the air guide plate 44 and the first air guide part 11 is γ, which is an acute angle. For example, the angle γ can be 30°, 45°, 60°, etc.

[0068] In this embodiment, the deflector plate 44 is designed to guide the airflow to the upper and middle air outlet areas, thereby improving the uniformity of the airflow and thus improving the air guiding efficiency.

[0069] Reference Figure 21 , 22 As shown, in another embodiment, in order to reduce wind resistance, the air guide plate 101 can retain only a basic frame, with multiple louvers 102b arrayed in the middle. The louvers 102b are formed by bending sheet metal to create an upward tilt angle, and there are air guide holes between adjacent louvers 102b. This arrangement can effectively reduce wind resistance and effectively improve the situation of short circuit in the wind field.
