Abstract
Description
Technical Field
[0001] This invention relates to the field of heat dissipation, and more specifically to a housing device and a heat dissipation system. Background Technology
[0002] Electrical components tend to generate significant heat after operating for a period of time, especially when their density is high. The heat generated by the electrical modules formed after installation increases considerably. Currently, most electrical components are housed in container-like enclosures or cabinets, arranged vertically. These enclosures or cabinets are typically equipped with external backpack-style air conditioners for cooling. Generally, the exhaust and intake vents of these air conditioners are spaced vertically, resulting in faster heat dissipation for components closer to the exhaust vents and slower cooling for those further away. This uneven heat dissipation affects the lifespan of the electrical components. This is particularly problematic when the electrical components are batteries. Significant temperature variations exist between different locations within the enclosure, leading to poor temperature uniformity and inconsistent temperature differences between the front and rear ends of the battery. Over long-term system operation, this can cause uneven battery aging, affecting the overall charging and discharging performance of the system and posing a higher risk to system operation. Summary of the Invention

The second air vent includes several first return air vents and second return air vents. Each first return air vent is located between the air inlet cavity and the second return air vent.

In technical solution four, the housing assembly includes at least two housing frames arranged along the second direction. Adjacent housing frames are spaced apart, and the two ends of the spaced apart along the third direction are shielded to form a first gap. Each housing frame houses electrical components in layers along the first direction, and a second gap is formed between electrical components in adjacent layers on each housing frame. The second gaps on the same layer are connected to the first gaps to form the third air duct. When each electrical component is housed in each housing frame, it forms the electrical module. The second direction is perpendicular to the first sidewall and the third sidewall. The first direction is perpendicular to the second direction and the third direction.
[0009] Based on technical solution four, technical solution five is also provided. In technical solution five, the accommodating frame is provided with a plurality of shelves extending along a third direction along a first direction. The shelves accommodate the electrical components. Each shelf is provided with a first baffle plate and a second baffle plate at both ends along the third direction to form a second gap between the electrical components of adjacent shelves, allowing airflow to flow along the second direction.

In technical solution eight, the cabinet is further provided with a first partition and a second partition; the accommodating component extends from the first end to the second end along the second direction; the first partition connects the first end of the accommodating component and the first side wall, and the second partition connects the second end of the accommodating component and the third side wall, so that the electrical module and the fourth side wall form a compartment isolated from the second air duct; the surface of the first partition facing the second side wall forms the cavity wall of the air inlet chamber, the cavity wall of the air outlet chamber, and the side wall of the air passage chamber.

[0014] Technical solution ten, a heat dissipation system, comprising a housing device as described in any one of technical solutions one to nine, a plurality of electrical components and a cooling component, wherein the housing assembly houses each of the electrical components in layers along a first direction to form an electrical module, and the cooling component is provided with an exhaust port and an intake port; the cooling component is mounted on a first side wall and the exhaust port is connected to the intake port, and the intake port is connected to the outlet port.
[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. In technical solution one, when the accommodating component houses various electrical components to form an electrical module, airflow flows from the first air inlet into the air inlet cavity, through the first air outlet to the first air duct, then into the second air duct, then into the third air duct, and finally through the air chamber to the second air outlet, and then out to the air outlet. Since the airflow in the first, second, and third air ducts all passes over the outer surface of the electrical components, the airflow basically flows around the outside of the electrical components, which is more conducive to removing heat from the electrical components. Since the first air outlet is opened along the third direction, the airflow from the first air outlet does not blow directly onto the electrical components, but blows towards the first air duct corresponding to the second and / or fourth side walls. Accordingly, the electrical components adjacent to the first air duct dissipate heat quickly because they are in the air duct. After the airflow gathers in the second air duct, it is concentrated and blown towards each of the third air ducts. Therefore, electrical components adjacent to the second air duct also dissipate heat quickly because they are located within the air duct. When airflow passes through each of the third air ducts, the heat on the adjacent surfaces of the electrical components is carried away by the airflow. That is, the housing device of the present invention is suitable for electrical components that dissipate heat mainly through heat conduction. In the present invention, the heat of the electrical components is dissipated to the outer surface and then carried away by the airflow flowing through each surface, thereby making the heat dissipation of the electrical components more even. In the present invention, the airflow converges in the second air duct and then blows concentratedly towards each of the third air ducts to carry away the heat on the surface of the electrical components, making the airflow flowing through each electrical component more even. Since the air inlet and air outlet are along the first direction The first and second air inlets are also arranged along the first direction. The airflow from the third air duct opposite to the air inlet flows along the first direction to the second air inlet, and the airflow from the third air duct opposite to the air outlet flows directly to the second air inlet. That is, in this invention, the length of the airflow path into the electrical component opposite to the air inlet and the length of the airflow path into the electrical component opposite to the air outlet are not much different, thus making the heat dissipation of each electrical component more balanced. In summary, when the electrical components mainly dissipate heat through heat conduction, the temperature of each electrical component is more balanced when using this technical solution, thereby effectively protecting the life of the electrical components.
[0017] 2. In technical solution two, the air passage area of the second return air inlet is larger than that of the first return air inlet. That is, the air passage area of the second air inlet, which is furthest from the air inlet cavity, is the largest. This is conducive to directing the airflow to the third air duct that is far away from the air inlet cavity in the first direction, so that the airflow to the electrical components near the air inlet cavity and far away from the air inlet cavity is larger, and the heat dissipation is more balanced.
[0018] 3. In technical solution three, each first return air outlet is opposite to at least part of the third air duct in the first direction, so that the airflow velocity of the third air duct corresponding to the first return air outlet is faster and it is easier to flow into the first return air outlet.
[0019] 4. In technical solution four, the housing component includes at least two housing frames, which are easy to install, and the housing component formed by the combination of multiple housing frames is more flexible and less expensive; the second gap on the same layer is connected to the first gap to form a third air duct, and the airflow can flow in the first direction in the first gap, so that the airflow in the second gap of the adjacent layer is more balanced, thus making it easier to achieve temperature uniformity.
[0020] 5. In technical solution five, each shelf is provided with a first wind baffle and a second wind baffle at both ends along the third direction. The first wind baffle and the second wind baffle cooperate with the adjacent electrical components to form a second gap, so that the airflow basically flows in the second direction within the second gap, the flow rate is faster, and the electrical module cooperates with the second side wall and / or the fourth side wall to form a first air duct.
[0021] 6. In technical solution six, the arrangement of two mounting plates facilitates the fixation of adjacent mounting brackets to each other, making them easy to assemble and disassemble, and ensuring the formation of the first gap.
[0022] 7. In technical solution seven, the first air vent is opposite to the second side wall, and the electrical module and the second side wall form a first air duct. The electrical module and the fourth side wall form a compartment isolated from the second air duct. When there is a heat dissipation difference between the two ends of the electrical component along the third direction, that is, when the electrical component is provided with a vent near the fourth side wall, the formation of the compartment prevents the airflow from rushing into the compartment, making it easier for the airflow to flow to the third air duct. The airflow speed is faster in the third air duct, and the airflow only flows into the vent of the electrical component near the fourth side wall in the third air duct, making the temperature difference between the two ends of the electrical component along the third direction more uniform.
[0023] 8. In technical solution eight, the setting of the first partition and the second partition is conducive to forming a compartment, and the structure is simple and practical; the surface of the first partition facing the second side wall forms the cavity wall of the air inlet chamber, the cavity wall of the air outlet chamber and the side wall of the air passage chamber, which is ingenious and makes it easier for the airflow of the second air duct to be concentrated and blown to the third air duct.
[0024] 9. In technical solution nine, the cabinet is equipped with a storage slot for installing monitoring devices or switches. The location of the storage slot makes maintenance easier. The electrical component is a battery. The battery has a ventilation opening near the fourth side wall, which allows the airflow from the third air duct to also blow into the battery to dissipate heat. Since the ventilation opening is close to the fourth side wall, the heat dissipation efficiency of the end of the electrical module near the fourth side wall is also high. This results in a smaller temperature difference between the end of the electrical module near the second side wall and the end near the fourth side wall, thus avoiding inconsistent battery aging and effectively extending the battery's lifespan.
[0025] 10. In technical solution ten, the present invention also discloses a heat dissipation system, including the above-mentioned housing device, several electrical components and a cooling component, wherein the temperature of each electrical component is more uniform, thereby effectively protecting the lifespan of the electrical components.

[0044] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."
[0045] See Figure 1-11 , Figure 1-11 A heat dissipation system is shown, including a housing, several electrical components 30, and a cooling component 40.
[0046] The housing device is used to house several electrical components 30, including a cabinet 10 and a housing assembly 20.
[0047] like Figure 2-3 As shown, the cabinet 10 has a first side wall 11, a second side wall 12, a third side wall 13, and a fourth side wall 14; the first side wall 11 is opposite to the third side wall 13, and the second side wall 12 is opposite to the fourth side wall 14; see also Figure 5-6 The cabinet 10 is provided with an air inlet chamber 01, an air outlet chamber 02, and an air passage chamber 03. The air inlet chamber 01 has an air inlet 011 and a first air passage 012; the air outlet chamber 02 has an air outlet 021 and a second air passage 022 opposite to the third side wall 13; the air passage chamber 03 connects only the first air passage 012 and the second air passage 022; the air inlet 011 and the air outlet 021 are located on the first side wall 11 and arranged along a first direction; the first air passage 012 is opened along a third direction. In this embodiment, the first side wall 11 and the third side wall 13 are both perpendicular to the second direction, and the second side wall 12 and the fourth side wall 14 are both perpendicular to the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. In this embodiment, the first direction is mainly a vertical first direction, and the second direction and the third direction are both horizontal directions.
[0048] See Figure 6 There are at least three second air vents 022, each arranged along a first direction. Each second air vent 022 includes several first return air vents 0221 and second return air vents 0222. Each first return air vent 0221 is located between the air inlet chamber 01 and the second return air vent 0222. The air passage area of the second return air vent 0222 is larger than that of the first return air vent 0221. In this embodiment, the air passage areas of each first return air vent 0221 are equal to facilitate processing and thus reduce costs.
[0049] See Figure 6-7 The cabinet 10 is also provided with a receiving slot 1571 located between the air inlet cavity 01 and the air outlet cavity 02. The opening of the receiving slot 1571 faces the air outlet cavity 03. The receiving slot 1571 is used to install monitoring devices or switches. The position of the receiving slot 1571 makes it easier to maintain.
[0050] In this embodiment, the air inlet cavity 01, the receiving groove 1571, and the air outlet cavity 02 are arranged sequentially along the first direction, wherein the air inlet cavity 01 is located at the top and the air outlet cavity 02 is located at the bottom. The area inside the cabinet 10 other than the air inlet cavity 01, the air outlet cavity 02, and the receiving groove 1571 forms an air passage cavity 03.
[0051] See Figure 2-4 The accommodating component 20 is placed in the air passage cavity 03, and it accommodates each electrical component 30 in layers along the first direction to form an electrical module. The electrical module is basically cuboid in shape. A first air duct 04 is formed between the electrical module and the second side wall 12 and / or the fourth side wall 14, which connects to the first air passage 012. A second air duct 05 is also formed between the electrical module and the third side wall 13, which connects to the first air duct 04. An air passage chamber 07 is also formed between the electrical module and the first side wall 11. The air passage chamber 07 is adjacent to the air inlet cavity 01 and the air outlet cavity 02 and connects to the second air passage 022. A third air duct 06 is also formed between the electrical components 30 in adjacent layers, which only connects the second air duct 05 and the air passage chamber 07.
[0052] In this embodiment, the electrical component 30 has a ventilation opening 31 near the fourth side wall. The first air vent 012 is opposite to the second side wall 12, and a first air duct 04 is formed between the electrical module and the second side wall 12. A compartment 08, isolated from the second air duct 05, is formed between the electrical module and the fourth side wall. Specifically, the electrical component 30 is cuboid in shape, with its length direction being the third direction and its width direction being the second direction. A ventilation opening 31 is provided on each of the two side walls near the end of the electrical component 30 closest to the fourth side wall 14. It should be understood that air can only enter the electrical component 30 through the ventilation openings 31; air cannot enter from other locations.
[0053] Specifically, see Figure 5 The first side wall 11 of the cabinet 10 is provided with a rectangular ventilation hole 111, see also Figure 2-3 and Figure 6-7The cabinet 10 also includes a first partition 151, a second partition 152, a third partition 153, a fourth partition 154, a fifth partition 155, a sixth partition 156, and a receiving element 157. The first partition 151, second partition 152, and third partition 153 are all parallel to the second side wall 12 and the fourth side wall 14. The first partition 151 and second partition 152 are respectively connected to the first side wall 11 and the third side wall 13 and are spaced apart along the second direction. The first partition 151 and third partition 153 are spaced apart along the third direction and are both connected to the first side wall 11. The height of the first partition 151 is higher than the height of the third partition 153. The fourth partition 156... 54 and the fifth partition 155 are parallel to the first sidewall 11 and are spaced apart along the first direction. The fourth partition 154 is located above the fifth partition 155. The fifth partition 155 connects the first partition 151 and the third partition 153. The sixth partition 156 is perpendicular to the first direction and connects the first partition 151, the fifth partition 155 and the third partition 153. The receiving member 157 is basically a box-shaped structure with one end open and the opening facing the air passage 03. The receiving groove 1571 is formed in the receiving member 157. The receiving member 157 is placed in the gap between the fourth partition 154 and the fifth partition 155 and is connected to the first partition 151 and the sixth partition 156. In this embodiment, the first sidewall 11, the first partition 151, the fourth partition 154, the sixth partition 156, the top wall of the cabinet 10, and the outer wall of the accommodating member 157 cooperate to form an air inlet cavity 01. The gap between the third partition 153 and the top wall of the cabinet 10 forms a first air outlet 012, that is, the first air outlet 012 is opposite to the second sidewall 12. The ventilation hole 111 located above the sixth partition 156 forms an air inlet 011. The first sidewall 11, the first partition 151, the fifth partition 155, the third partition 153, the sixth partition 156, and the bottom wall of the cabinet 10 cooperate to form an air outlet cavity 02. The second air outlet 022 is opened on the fifth partition 155 along the second direction. The ventilation hole 111 located below the sixth partition 156 forms an air outlet 021. The second air outlet 022 extends along the third direction. That is, the surface of the first partition 151 facing the second side wall 12 forms the cavity wall of the air inlet cavity 01, the cavity wall of the air outlet cavity 02, and the side wall of the air passage chamber 07.
[0054] In this embodiment, the housing component 20 extends from the first end to the second end along the second direction; the first partition 151 connects the first end of the housing component 20 and the first sidewall 11, and the second partition 152 connects the second end of the housing component 20 and the third sidewall 13, so that a compartment 08 isolated from the second air duct 05 is formed between the electrical module and the fourth sidewall 14. It can be seen that the compartment 08 can maximize the concentration of airflow from the second air duct 05 towards the third air duct 06, and avoid the temperature difference between the two ends of the electrical component 30 along the third direction. However, it should be understood that the first partition 151 can also connect the first end of the housing component 20 and the fourth sidewall 14, and the second partition 152 can also connect the second end of the housing component 20 and the fourth sidewall 14.
[0055] See Figure 11 The cooling component 40 is provided with an exhaust port 41 and an intake port 42; see also Figure 1-4 The cooling component 40 is mounted on the first side wall 11, with the exhaust port 41 connected to the air inlet 011 and the air intake port 42 connected to the air outlet 021. In this embodiment, the cooling component 40 is a backpack-style air conditioner, with the exhaust port 41 and the air intake port 42 arranged vertically at intervals. In a specific implementation, the cooling component 40 is embedded in the first side wall 11, and the sixth partition 156 is positioned to avoid the cooling component 40. The exhaust port 41 is opposite to the air inlet 011, and the air intake port 42 is opposite to the air outlet 021.
[0056] See Figure 5 and Figure 8 The accommodating assembly 20 includes at least two accommodating frames 21 arranged along the second direction, see [reference]. Figure 2-4 Adjacent housing frames 21 are spaced apart, and the two ends of the spacer along a third direction are shielded to form a first gap 061. Each housing frame 21 accommodates electrical components 30 in layers along the first direction, and a second gap 062 is formed between electrical components 30 in adjacent layers on each housing frame 21. The second gap 062 in the same layer communicates with the first gap 061 to form a third air duct 06. When each electrical component 30 is accommodated in each housing frame 21, it forms an electrical module. The housing assembly 20 includes at least two housing frames 21, which is easy to install, and the housing assembly 20 formed by the combination of multiple housing cavities is more flexible and less expensive. The second gap 062 in the same layer communicates with the first gap 061 to form a third air duct 06, and the airflow can flow along the first direction in the first gap 061, making the airflow in the second gap 062 of adjacent layers more balanced, thereby making it easier to achieve temperature uniformity.
[0057] Specifically, see Figure 8 The housing 21 is provided with a plurality of shelves 211 extending in a third direction along the first direction. The shelves 211 house electrical components 30. (See also...) Figure 9Each shelf 211 has a first baffle plate 2111 and a second baffle plate 2112 at both ends along the third direction to form a second gap 062 between the electrical components 30 of adjacent shelves, allowing airflow to flow in the second direction. The arrangement of the first baffle plate 2111 and the second baffle plate 2112 also ensures that the electrical module cooperates with the second side wall 12 to form a first air duct 04, and cooperates with the fourth side wall 14 to form a compartment 08. It can be seen that the side of the cuboid electrical module opposite to the second side wall 12 and the side opposite to the fourth side wall 14 cannot receive or discharge air, only the side opposite to the third side wall 13 can receive air, and the side opposite to the first side wall 11 can discharge air. See [reference]. Figure 2-4 An air passage chamber 07 is formed between the electrical module and the fourth partition 154, the fifth partition 155, and the housing 157. In practical applications, each shelf 211 may include only two guide rails spaced apart along the second direction and extending along the third direction, or it may include two of the aforementioned guide rails and a shelf 2113 located between the two guide rails. The electrical component 30 is slidably mounted on the two guide rails to be housed in the housing 21. In this embodiment, the shelf 211 includes two guide rails and a shelf 2113 located between the two guide rails. The first baffle plate 2111 and the second baffle plate 2112 extend downward from both ends of the shelf 2113, and the shelf 2113 has several through holes along the first direction to facilitate airflow and heat dissipation for the electrical component 30.
[0058] See Figure 8 The accommodating frame 21 has mounting plates 212 at both ends along a third direction facing adjacent accommodating frames 21. The two mounting plates 212 cooperate with the two adjacent accommodating frames 21 to form a first gap 061. In specific implementation, each accommodating frame 21 is formed by four columns, several beams, several trusses, and shelves 211 fixedly connected together. Each shelf 211 is fixedly connected to four columns; this part is prior art and will not be described further in this embodiment. The two mounting plates 212 are correspondingly formed on the two columns of the accommodating frame 21. In this embodiment, see [reference needed]. Figure 2-3 The mounting plate 212 is a C-shaped groove. The opening of the C-shaped mounting plate 212 is away from the adjacent mounting frame. The bottom walls of the two mounting plates 212 of the two adjacent housing frames 21 are in contact with each other, which is more conducive to the fixed connection of the adjacent housing frames 21, more conducive to disassembly and assembly, and ensures the formation of the first gap 061.
[0059] In this embodiment, the air inlet cavity 01 and the air outlet cavity 02 are respectively connected to the top and bottom of the cabinet 10. Specifically, the upper and lower ends of the first partition 151 and the second partition 152 are respectively connected to the top and bottom walls of the cabinet 10, the bottom end of the third partition 153 is connected to the bottom wall of the cabinet 10, and the upper end of the fourth partition 154 is connected to the top wall of the cabinet 10. Thus, the air passage area of the first air outlet 012 is large, and the number of second air outlets 022 is relatively large. There are gaps between the upper and lower ends of each housing rack 21 and the top and bottom walls of the cabinet 10 to facilitate airflow. Similarly, the two ends of the gap along the third direction are also blocked to allow the airflow to flow in the second direction.
[0060] In this embodiment, each first return air inlet 0221 is opposite to at least a portion of the third air duct 06 in a first direction, so that the airflow velocity of the third air duct 06 corresponding to the first return air inlet 0221 is faster and it is easier to flow into the first return air inlet 0221.
[0061] In this embodiment, the electrical component 30 is a battery, and each shelf 211 houses one electrical component 30.
[0062] In practical applications, the cabinet 10 is also provided with an installation cavity 09 that is isolated from the air passage cavity 03. The installation cavity 09 can be equipped with control components to control each electrical component 30, and power distribution components to supply power to each electrical component.
[0063] In practical applications, the second side wall 12 and the fourth side wall 14 of the cabinet 10 can be formed by cabinet doors, allowing maintenance of the electrical components 30 when the cabinet doors are opened.
[0064] When the housing assembly 20 houses the electrical components 30 to form an electrical module, airflow flows from the first air inlet 011 into the air inlet cavity 01, passes through the first air outlet 012 to the first air duct 04, then flows into the second air duct 05, then into the third air duct 06, and then through the air chamber 07 to the second air outlet 022, finally exiting through the air outlet 021. Since the airflow from the first air duct 04, the second air duct 05, and the third air duct 06 all passes over the outer surface of the electrical components 30, the airflow basically flows around the outside of the electrical components 30, which is more conducive to removing the heat from the electrical components 30. Since the first air outlet 012 is opposite to the second side wall 12, the airflow from the first air outlet 012 does not blow directly onto the electrical components 30, but blows towards the first air duct 04 corresponding to the second side wall 12. Accordingly, the electrical components 30 adjacent to the first air duct 04 dissipate heat quickly because they are in the air duct. After the airflow gathers in the second air duct 05, it is concentrated and blown towards each of the third air ducts 06. Therefore, the electrical component 30 adjacent to the second air duct 05 also dissipates heat quickly because it is located in the air duct. When the airflow flows through each of the third air ducts 06, the heat on the adjacent surfaces of the electrical component 30 is carried away by the airflow. That is, the housing device of the present invention is suitable for electrical components 30 that dissipate heat mainly by heat conduction. After the heat of the electrical component 30 is dissipated to the outer surface, it is carried away by the airflow flowing through each surface, thereby making the heat dissipation of the electrical component 30 more balanced. In the present invention, the airflow converges in the second air duct 05 and then blows it towards each of the third air ducts 06 to carry away the heat on the surface of the electrical component 30, making the airflow flowing through each electrical component 30 more balanced. Since the first air outlet 012 and the second air outlet 022 are also arranged along the first direction, the airflow flowing out of the third air duct 06 opposite to the air inlet cavity 01 flows along the first direction to the second air outlet 022, and the airflow flowing out of the third air duct 06 opposite to the air outlet cavity 02 flows directly to the second air outlet 022. The airflow path lengths to the second air vent 022, i.e., to the electrical component 30 opposite to the air inlet cavity 01 and the electrical component 30 opposite to the air outlet cavity 02, are not significantly different, thus making the heat dissipation of each electrical component 30 more balanced. In this invention, a compartment 08 is formed between the electrical module and the fourth side wall 14, which prevents airflow from rushing in and makes it easier for the airflow to flow to the third air duct 06. The airflow velocity is faster in the third air duct 06, and the airflow only flows into the ventilation port 31 of the electrical component 30 near the fourth side wall 14 in the third air duct 06 to dissipate heat from the electrical component 30. Since the ventilation port 31 is close to the fourth side wall 14, the heat dissipation efficiency of the end of the electrical module near the fourth side wall 14 is also higher, thus making the temperature difference between the end of the electrical module near the second side wall 12 and the end near the fourth side wall 14 smaller, thereby avoiding inconsistent battery aging and effectively extending the battery's service life.Since the air passage area of the second return air inlet 0222 is larger than that of the first return air inlet 0221, that is, the air passage area of the second air passage inlet 022 at the bottom is the largest, it is beneficial to make the airflow flow to the third air duct 06 at the bottom, so that the airflow of the electrical components 30 near the air inlet cavity 01 and far away from the air inlet cavity 01 is larger, and the heat dissipation is more balanced.
[0065] In practical applications, if the surface of the electrical component 30 does not have ventilation openings, or if the ventilation openings are only on the upper or lower surface of the electrical component 30, a first air passage 012 opposite to the fourth side wall 14 can be opened on the first partition 151, that is, there are two first air passages 012. In this case, the second partition 152 can be omitted, so that a first air duct connected to the first air passage 012 is formed between the electrical module and the fourth side wall 14. At this time, after the airflow from the air inlet cavity 01 flows out, it can flow along the first air duct 04 corresponding to the second side wall 12 and the first air duct 04 corresponding to the fourth side wall 14, and then gather in the second air duct 05 corresponding to the third side wall 13, and then be concentrated and blown to each third air duct 06 and then flow to the air outlet cavity 02 through the air passage chamber 07. At this time, the airflow can basically flow through each surface of the electrical component 30. After the heat of the electrical component 30 is dissipated to the outer surface, it is carried away by the airflow flowing through each surface, and the heat dissipation is more balanced.
[0066] In summary, the heat dissipation system of the present invention provides a more uniform temperature distribution among electrical components 30 when the electrical components 30 primarily dissipate heat through thermal conduction, thereby effectively protecting the lifespan of the electrical components 30.
