A cooling area is provided on the housing near the air outlet. The inner side of the cooling area is thermally connected to the cooling conductor, and the outer side is exposed to the wearing space.

[0006] In one alternative embodiment, the neckband includes two fans; the two fans are disposed at both ends of the housing along the length of the housing, with the air outlet sides of the two fans facing each other.

[0007] In one alternative embodiment, the cooling element comprises a plurality of cooling elements arranged sequentially along the length of the housing, and the hot ends of the plurality of cooling elements are thermally connected to a heat sink.

[0009] The heat sink, the cooling component, and the cooling conductor are positioned between the air outlet sides of the two fans.

[0010] In one alternative embodiment, the air inlets are respectively provided at both ends of the housing along its length; the heat dissipation vent is provided between the two air inlets and spaced apart from the air inlets;

[0011] One of the air inlets is connected to the air intake side of one of the fans, and the airflow blown out from the air outlets of the two fans passes through the heat sink and flows out from the heat sink.

[0012] In one alternative embodiment, the heat sink is provided with a plurality of airflow gaps along the length of the housing. The airflow gaps are respectively connected to the air outlet side of a fan at both ends of the housing along the length of the housing. The airflow outlet of the airflow gap is located on the side away from the cooling component, and the airflow outlet is connected to the heat dissipation port.

[0013] In one alternative embodiment, air outlets are provided at both ends of the housing along its length on the side of the housing near the wearing space, and the cooling area is provided in the middle of the air outlets at both ends.

[0014] The cooling components located at both ends of the housing along its length are respectively provided with multiple airflow channels, wherein the air outlet side corresponding to one fan and the air outlet adjacent thereto are connected through the airflow channel of one cooling component; the air outlet side corresponding to another fan and the air outlet adjacent thereto are connected through the airflow channel of another cooling component.

[0015] In one alternative, the sidewall of the air outlet slopes relative to the normal of the housing wall towards the cooling zone from the side closer to the cooling element to the side farther away.

[0019] This embodiment of the invention features a fan installed at the neckband. The fan's outlet is aligned with the heat sink and the cooling conductor. The airflow from the outlet is divided into two streams: one stream flows over the surface of the heat sink, dissipating the heat generated on the cooling component into the external environment through the vent, ensuring timely removal of heat from the cooling component, preventing heat short-circuiting, and improving cooling efficiency; the other stream passes through the cooling conductor, where it cools down upon contact with the surface, becoming cold air. This cold air flows out from the outlet and blows towards the back of the neck, accelerating the airflow around the skin and cooling the skin, preventing localized stuffiness. Simultaneously, the cold air, upon contact with the skin, carries away sweat, preventing sweat accumulation in the cooling area and keeping the surface dry.

[0040] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0041] Please see Figures 1-10 , Figure 1A perspective view of an embodiment of the neck-hanging air conditioner 100 of this utility model is shown. The neck-hanging air conditioner 100 includes: a neck-hanging part 101 and two handle parts 102 respectively connected to both ends of the neck-hanging part 101 in the length direction. The handle parts 102 and the neck-hanging part 101 enclose a wearing space 103. Figure 4 As shown, the neckpiece 101 includes a housing 1 and a fan 2, a cooling component 4, a cooling conductive component 5, and a heat dissipation component 3 installed within the housing; as Figure 2 As shown, the side of the housing 1 away from the wearing space 103 is provided with an air inlet 10 and a heat dissipation vent 12, as... Figure 3 As shown, an air outlet 11 is provided on the side near the wearing space 103; as Figure 6 As shown, the hot end of the heat sink 3 and the cooling component 4 are thermally connected, and the cold end of the cooling component 4 is thermally connected; the air inlet side 22 and the air inlet 10 of the fan 2 are connected to drive airflow from the outside into the fan 2, and the air outlet side 21 of the fan 2 is arranged facing the heat sink 3 and the cold end of the cooling component 5 to blow airflow from the air outlet side 21 to the heat sink 3 and the cold end of the cooling component 5. Part of the airflow flows out from the heat sink 12 after passing through the heat sink 3, and the other part of the airflow flows out from the air outlet 11 after passing through the cold end of the cooling component 5; as shown Figure 3 As shown, a cooling area 15 is provided near the air outlet 11 on the housing 1. The inner side of the cooling area 15 is thermally connected to the cooling conductor 5, and the outer side is exposed to the wearing space 103. In this embodiment, a fan 2 is provided on the neckband 101. The air outlet 21 of the fan 2 is directed towards the heat sink 3 and the cooling conductor. The airflow from the air outlet 21 is divided into two streams: one stream flows over the surface of the heat sink 3 and discharges the heat generated on the cooling component 4 from the heat sink 12 to the outside environment, ensuring that the heat on the cooling component 4 can be discharged to the outside in time and improving the cooling efficiency; the other stream passes through the cooling conductor 5 and becomes cold air when it comes into contact with the surface of the cooling conductor 5. The cold air flows out from the air outlet 11 and blows towards the back of the neck, accelerating the airflow speed around the skin and cooling the skin on the back of the neck to avoid local stuffiness. At the same time, after the cold air comes into contact with the skin, it can remove the sweat on the skin surface, preventing sweat from accumulating in the cooling area and keeping the surface of the cooling area dry.

[0042] like Figure 1 As shown, two handles 102 are respectively connected to the two ends of the neckband 101 in the length direction, forming a U-shaped neckband air conditioner 100. At least one fan 2 is provided in each of the two handles 102. An air inlet 10 is provided on the side of the handle 102 away from the wearing space 103, and an air outlet 11 is provided on the side closer to the wearing space 103. The fan 2 draws air from the air inlet 10 into the handle 102 and blows it from the air outlet 11 towards the wearing space 103, so that the neckband air conditioner 100 can vent air from the two handles 102, thereby providing multi-directional airflow to the human body.

[0043] The shell 1 has a hollow structure inside. An air inlet 10 and a heat dissipation vent 12 are provided on the side of the shell 1 away from the wearing space 103, and an air outlet 11 is provided on the side of the shell 1 close to the wearing space 103. The air inlet 10 is connected to the air outlet 11 and the heat dissipation vent 12 through the hollow structure of the shell 1. The cooling component 4 is installed inside the housing 1. The cold end of the cooling component 4 faces the air outlet 11 and is in contact with the cooling guide 5. The side of the cooling guide 5 away from the cold end of the cooling component 4 is opposite to the air outlet 11. The hot end of the cooling component 4 is in contact with the heat sink 3. The side of the heat sink 3 away from the hot end of the cooling component 4 is connected to the heat dissipation port 12. The air outlet side 21 of the fan 2 is located on the side close to the cooling component 4. The airflow blown out by the air outlet side 21 blows along the length of the housing 1 to the sides of the cooling guide 5 and the heat sink 3, so that the airflow is split into two parts. One part of the airflow flows through the surface of the heat sink 3 away from the hot end of the cooling component 4 and flows out from the heat dissipation port 12. The other part of the airflow flows through the surface of the cooling guide 5 for cooling and then flows out from the air outlet 11.

[0044] One implementation method of this embodiment is as follows: Figure 4 As shown, the housing 1 includes an upper housing 13 and a lower housing 14. An air inlet 10 and a heat dissipation outlet 12 are provided on the upper housing 13. A cooling component 4 is disposed between the upper housing 13 and the lower housing 14, and a heat dissipation component 3 is disposed between the upper housing 13 and the cooling component 4. A cooling conductive component 5 is disposed between the lower housing 14 and the cooling component 4. A cooling zone 15 and an air outlet 11 are provided on the lower housing 14. Figure 5 As shown, a partition plate 63 is also provided inside the housing 1, such as Figure 7 As shown, the isolation plate 63 is disposed between the air outlet side 21 of the fan 2 and the cooling component 4. The upper housing 13 and the isolation plate 63 form a first channel 16, and the lower housing 14 and the isolation plate 63 form a second channel 17. The first channel 16 is connected to the heat dissipation port 12 and the heat dissipation component 3 is disposed between the first channel 16 and the heat dissipation port 12. The second channel 17 is connected to the air outlet 11 and the cooling component 5 is placed between the second channel 17 and the air outlet 11.

[0045] Specifically, the isolation plate 63 is disposed at one end of the cooling component 4 along the length of the housing 1. An upper cavity is formed between the side of the cooling component 4 facing away from the wearing space 103 and the upper housing 13. A first channel 16 is formed between the side of the isolation plate 63 facing away from the wearing space 103 and the upper housing 13. A lower cavity is formed between the side of the cooling component 4 near the wearing space 103 and the lower housing 14. A second channel 17 is formed between the side of the isolation plate 63 near the wearing space 103 and the lower housing 14. The air outlet side 21 of the fan 2 faces the first channel 16 and the second channel 17. After being accelerated by the fan 2, the airflow flows out from the air outlet side 21 and towards the first channel 16 and the second channel 17. The first channel 16 and the heat dissipation port 12 are connected through the upper cavity. Part of the airflow from the air outlet 21 enters the upper cavity through the first channel 16 and comes into contact with the surface of the heat dissipation component 3 before flowing out from the heat dissipation port 12, thereby dissipating heat from the hot end of the cooling component 4. The second channel 17 and the air outlet 11 are connected through the lower cavity. Part of the airflow from the air outlet 21 enters the lower cavity through the second channel 17 and comes into contact with the surface of the cooling component 5 before flowing out from the air outlet 11, blowing cool air onto the skin of the back of the neck and keeping the skin surface dry.

[0046] An isolation plate 63 is disposed between the fan 2 and the cooling component 4. A first channel 16 and a second channel 17 are formed on both sides of the isolation plate 63. The airflow is divided into two parts by the isolation plate 63, and the two parts of the airflow are directed to the heat sink 3 and the cooling conductor 5 respectively. The fan 2 dissipates heat from the hot end of the cooling component 4 and blows cool air to the user's neck skin. Furthermore, the cooperation between the fan 2 and the isolation plate 63 ensures that the airflow to the heat sink 3 and the cooling conductor 5 is relatively even, avoiding insufficient airflow to the heat sink 3, which would result in untimely heat dissipation, or insufficient airflow to the cooling conductor 5, which would result in insufficient cool air flowing out of the air outlet 11, thus affecting the cooling effect.

[0047] In one implementation, such as Figure 6As shown, the neckband 101 includes two fans 2; the two fans 2 are disposed on both sides of the cooling component 4 and the heat sink 3, with the air outlet sides 21 of the two fans 2 facing each other. The two fans 2 are disposed at both ends of the housing 1 along its length, with the air outlet sides 21 of the two fans 2 facing each other. The heat sink 3, cooling component 4, and heat sink 3 are disposed between the two opposing air outlet sides 21, and the airflow from the two air outlet sides 21 flows from both ends of the heat sink 3 towards the middle. By setting a fan 2 at each end of the length of the housing 1, the airflow to the heat sink 3 and the cooling component 5 can be increased, quickly cooling the heat sink 3 and ensuring the heat dissipation effect of the cooling component 4. At the same time, it ensures that the airflow of cold air blown to the user is sufficient, improving the user experience of the neck air conditioner 100. In addition, it also avoids uneven heat dissipation of the heat sink 3, ensuring that the heat at each position on the heat sink 3 can be effectively removed. Finally, setting the fans 2 at both ends of the length of the housing 1 allows the neck part 101 to maintain balance when worn, preventing the neck air conditioner 100 from shifting to the heavier end due to excessive weight on one end.

[0048] like Figure 2 As shown, air inlets 10 are provided at both ends of the housing 1 along the length direction; heat dissipation vents 12 are provided between the two air inlets 10 and spaced apart from the air inlets 10; one air inlet 10 is connected to the air inlet side 22 of a fan 2, and the airflow blown out by the air outlet side 21 of the two fans 2 flows out from the heat dissipation vent 12 after passing through the heat dissipation component 3 respectively.

[0049] like Figure 7 As shown, a mounting cavity 64 is provided at each end of the housing 1 along its length. Each mounting cavity 64 is connected to an air inlet 10, and the fan 2 is installed in the mounting cavity 64. The air inlets 10 are located at both ends of the housing 1 along its length, and a large distance is maintained between the air inlets 10 at both ends to avoid mutual interference between the airflow paths of the two airflow paths during the process of airflow entering the mounting cavity 64 from the air inlet 10.

[0050] like Figure 2 As shown, the heat dissipation vent 12 is located between the two air inlets 10 on the upper housing 13. Airflow flows into the housing 1 from the air inlet 10 and flows out from the heat dissipation vent 12. The air inlet 10 and the heat dissipation vent 12 are spaced apart to prevent the airflow flowing out from the heat dissipation vent 12 from re-entering the housing 1 from the air inlet 10, ensuring that the airflow entering the housing 1 from the two air inlets 10 is at room temperature.

[0051] like Figure 9 As shown, the heat sink 3 is provided with multiple airflow gaps 32 along the length of the housing 1. The airflow gaps 32 are connected to the air outlet side 21 of a fan 2 at both ends of the housing 1 along the length. The airflow outlet of the airflow gap 32 is located on the side away from the cooling component 4, and the airflow outlet is connected to the heat sink 12.

[0052] Multiple heat sinks 31 are arranged on the side of the heat sink 3 away from the cooling component 4. These heat sinks 31 are regularly arranged along the length of the housing 1, with an airflow gap 32 between adjacent heat sinks 31. The length of the airflow gap 32 is parallel to the length of the housing 1. The airflow gap 32 connects to both ends of the housing 1 along its length via a first channel 16 and the exhaust side 21 of a fan 2, respectively. Airflow enters the first channel 16 from the exhaust side 21 and then flows through the airflow gap 32, contacting the surfaces of two adjacent heat sinks 31 and reducing their surface temperature. The airflow between adjacent heat sinks 31 flows from the side closer to the cooling component 4 to the side farther away, exiting through the airflow gap 32 and then flowing out through the heat dissipation port 12. By arranging the multiple heat sinks 31 on the heat sink 3 to form the airflow gap 32, the airflow flows within the airflow gap 32, increasing the surface contact area between the airflow and the heat sink 3, enabling rapid heat dissipation from the heat sink 3, and ensuring the normal temperature of the cooling component 4.

[0053] In one implementation of this embodiment, such as Figure 6 As shown, the neckband 101 includes multiple cooling components arranged sequentially along the length of the housing. The hot ends of these components are connected to a heat sink via thermal conductivity. The multiple cooling components are arranged along the length of the housing, dividing the interior into an upper and lower cavity. This ensures that the airflow used to dissipate heat from the heat sink and the airflow used to cool the cooling components and blown towards the body from the outlet do not mix. Simultaneously, the multiple cooling components are arranged to form a curve that conforms to the back of the neck, improving the fit between the overall curve of the neckband 101 and the back of the neck. Furthermore, the cooling of different components can be controlled according to the varying cold sensitivity of different areas of the back of the neck. A heat sink is connected to the hot ends of the multiple cooling components via thermal conductivity. When the hot end of one cooling component overheats, the heat from that component can be transferred to other parts of the heat sink, thus adjusting the temperature of the hot end of the cooling component in a timely manner.

[0054] In one implementation of this embodiment, such as Figure 6 As shown, the neck hanging part 101 includes multiple cooling elements, which are arranged sequentially along the length of the shell, and the cooling elements 5 and the cooling elements 4 are arranged in a one-to-one correspondence.

[0055] like Figure 6As shown, multiple cooling elements 5 are arranged along the length of the housing 1. The cold end of each cooling element 4 is thermally connected to a cooling element 5. Airflow from the outlet side 21 of the first end fan 2 along the length of the housing enters the lower cavity through the second channel 17, flows through the first end cooling element 5, and exits from the outlet 11. Airflow from the outlet side 21 of the second end fan 2 along the length of the housing enters the lower cavity through the second channel 17, flows through the second end cooling element 5, and exits from the outlet 11, rapidly reducing the temperature of the airflow. The cooling element 5 located in the middle is thermally connected to the cold end of the cooling element 4 on one side and connected to the inner wall of the cooling area 15 of the lower housing 14 on the other side, so as to transfer the cold air on the cooling element 5 to the cooling area 15, reducing the temperature of the cooling area 15. When the skin is in contact with the cooling area 15, it can cool down in time. Meanwhile, the middle cooling guide 5 and the side wall of the lower housing 14 are directly attached to each other, which prevents the airflow at the first end and the second end from colliding with the middle cooling guide 5 and causing the airflow direction to change. This allows the airflow in the lower cavity to flow smoothly out of the air outlet 11, ensuring that the amount of cold air blown to the back of the neck is sufficient.

[0056] like Figure 3 As shown, air outlets 11 are provided at both ends of the housing 1 along its length on the side of the housing 1 near the wearing space 103, and a cooling area 15 is provided in the middle of the air outlets 11 at both ends; Figure 9 and 10 As shown, the cooling guides 5 located at both ends of the housing 1 along the length direction are respectively provided with multiple airflow channels 52. The air outlet side 21 of one fan 2 and the air outlet 11 adjacent to it are connected through the airflow channel 52 of one cooling guide 5; the air outlet side 21 of another fan 2 and the air outlet 11 adjacent to it are connected through the airflow channel 52 of another cooling guide 5.

[0057] like Figure 9 and 10As shown, multiple cooling fins 51 are respectively provided on the first end and the second end of the cooling guide 5 along the length direction of the shell. An airflow channel 52 is formed between two adjacent cooling fins 51. The airflow channel 52 is arranged along the length direction of the shell 1. One end of the cooling guide 5 away from the middle position is connected to the second channel 17. The side of the airflow channel 52 near the air outlet 11 is open, so that the airflow channel 52 and the air outlet 11 are connected. The airflow discharged by the fan 2 at the first end along the length direction of the shell enters the airflow communication of the cooling guide 5 through the second channel 17 at the first end, flows over the surface of the cooling guide 5 at the first end, and flows out from the air outlet 11 at the first end. The airflow discharged by the fan 2 at the second end along the length direction of the shell enters the airflow communication of the cooling guide 5 through the second channel 17 at the second end, flows over the surface of the cooling guide 5 at the second end, and flows out from the air outlet 11 at the second end. The cooling guide 5 located in the middle separates the space at the left and right ends of the lower cavity along the length of the shell, preventing airflow from colliding in the lower cavity and ensuring that the airflow can flow out smoothly from the corresponding air outlet 11.

[0058] like Figure 3 As shown, the cooling compress area 15 is set between the air outlet at the first end and the air outlet 11 at the second end along the length of the shell. By setting the cooling compress area 15, the temperature of the part of the lower shell 14 that is close to the wearing space 103 and in contact with the skin of the back of the neck is kept low, so as to avoid the skin from getting stuffy and sweating due to the contact between the shell 1 and the skin. At the same time, air outlets 11 are set at both ends of the lower shell between the cooling compress area 15, so that the airflow can flow through the cooling conductor 5 and then flow out from the air outlets 11, blowing towards the back of the neck, keeping the skin of the back of the neck dry and removing the heat from the surface of the skin of the back of the neck in time.

[0059] like Figure 6 As shown, a metal part 19 is provided on the lower housing 14. Along the length of the housing 1, the cooling conductor 5 located in the middle is thermally connected to the inner wall of the metal part 19. This thermal connection between the metal part 19 and the cooling conductor 5 allows for rapid temperature reduction of the metal part 19. Skin contact with the metal part 19 achieves rapid cooling of the skin surface. The cooling conductor 5 at the first and second ends along the length of the housing is connected to the inner wall of the metal part 19 on the side away from the cooling component 4. An airflow channel 52 on the cooling conductor 5 connects to the air outlet 11 on the side away from the cooling component 4. As the airflow flows along the airflow channel 52, it passes over the surface of the cooling conductor 5 and is blown onto the skin surface from the air outlet 11, ensuring smooth airflow out of the lower cavity. By utilizing the metallic properties of the metal part 19, the cooling effect is ensured, improving the usability of the neck-mounted air conditioner 100.

[0060] This embodiment allows for independent control of the cooling intensity in different areas (such as the left, middle, and right sides of the neck) by setting up cooling components 4, adapting to the temperature sensitivity of different locations on the back of the neck. Furthermore, a malfunction in a single cooling component 4 will not affect the normal operation of the others. The arrangement of multiple cooling components 4 and multiple cooling conductors 5 along the length of the housing 1 better conforms to the curve of the back of the neck. Additionally, the number of cooling components 4 activated can be selectively controlled according to the user's cooling needs. Three cooling conductors 5 and three cooling components 4 are arranged along the length of the housing 1. The cold ends of each cooling conductor 5 and each cooling component 4 are thermally connected. The cooling conductors 5 located at the first and second ends along the length of the housing are used to cool the airflow and control the airflow from the airflow channel 52 to the air outlet 11 and towards the user. The cooling conductor 5 located in the middle is used for thermal conduction with the inner wall of the metal component 19 to reduce the perceived temperature of the metal component 19, achieving rapid cooling through contact between the metal component 19 and the skin.

[0061] In another implementation of this embodiment, the neck-mounted air conditioner 100 includes a cooling component 4 and a cooling conductor 5. The cooling conductor 5 has multiple cooling fins 51 at both ends along the length of the housing 1. An airflow channel 52 is formed between adjacent cooling fins 51. The air outlet sides 21 of the two fans 2 blow air towards both ends of the cooling fins 51, causing some airflow to enter the airflow channel 52 along the second channel 17 and contact the surface of the cooling fins 51 for rapid cooling. The airflow then blows from the air outlet 11 towards the skin on the back of the neck. The cooling conductor 5 is thermally connected to the lower housing 14 at its middle position, or thermally connected to the inner wall of the metal component 19 at its middle position, to reduce the temperature of the cooling area 15 on the lower housing 14 or the metal component 19, so that the cooling area 15 can cool the skin when it is in contact with the skin. By using a longer cooling component 4 and a cooling conductor 5, the overall cooling efficiency of the air conditioner is improved. At the same time, the internal circuitry of the casing 1 and the fixing structure of the cooling component 4 and the cooling conductor 5 are reduced, thereby reducing the overall weight of the neck-mounted air conditioner 100.

[0062] In one implementation of this embodiment, such as Figure 3 and Figure 8 As shown, the sidewall of the air outlet slopes towards the cooling area from the side closest to the cooling component to the side furthest away from the housing wall. In other words, the airflow direction of the air outlet is tilted towards the cooling area. As the cooled airflow flows out of the air outlet 11 via the sidewall 18, which slopes from the side closest to the cooling component to the side furthest away from the cooling component, the sidewall 18 guides the airflow towards the back of the neck corresponding to the cooling area. This allows the airflow to come into contact with more skin surface during its flow, achieving more effective cooling. Simultaneously, by guiding the airflow, it ensures that the airflow can contact the skin of the back of the neck where the cooling area 15 is in contact, carrying away sweat from the skin surface and preventing the area from not drying properly due to contact with the cooling area 15.

[0063] like Figure 3 As shown, the air outlets 11 at both ends of the cooling area 15 along the length of the housing 1 are staggered along the height of the housing 1. That is, the air outlets 11 at the first end and the second end of the housing 1 are staggered along the height of the housing 1. By tilting the sidewalls 18 of the air outlets 11 from the side closer to the cooling element to the side farther away from the cooling element, the airflow from the first end and the second end is guided to blow towards the back of the neck. This causes the airflow from the air outlets 11 at both ends to collide, resulting in a change in the airflow direction and affecting the cooling effect on the skin of the back of the neck. By staggering the air outlets 11 at both ends of the cooling area along the height of the housing 1, the airflow from the air outlet 11 at the higher position blows towards the skin of the back of the neck in the higher area, and the airflow from the air outlet 11 at the lower position blows towards the skin of the back of the neck in the lower area. The airflow from the air outlets 11 at both ends contacts the skin of the back of the neck as much as possible, improving the cooling effect of the neck hanger 101 on the back of the neck. When the neck-mounted air conditioner 100 is worn on the back of the user's neck, the height direction of the housing 1 is parallel to the height direction of the human body. At the same time, the cooling airflow guides 5, which are set at the first and second ends of the housing along the length direction, are offset in the height direction of the housing 1. The air outlet side 21 of the fan 2 at the first and second ends is offset in the height direction of the housing 1. The second channel 17 at the first and second ends is offset in the height direction of the housing 1. This ensures that the airflow enters the airflow channel 52 of the cooling airflow guide 5 from the air outlet side 21 to the second channel 17, flows from the airflow channel 52 to the air outlet 11, and blows towards the user from the air outlet 11, ensuring smooth airflow along this airflow path.

[0064] like Figure 6 and Figure 7 As shown, the neck hanger 101 includes a bracket 6, which is placed between the upper housing 13 and the lower housing 14. The bracket 6 includes an upper bracket 61 and a lower bracket 62. The upper bracket 61 is located between the heat sink 3 and the upper housing 13 and is fixedly connected to the upper housing 13. The lower bracket 62 is located between the lower housing 14 and the cooling component 5 and is fixedly connected to the lower housing 14. The heat sink 3, the cooling component 4, and the cooling component 5 are fixedly connected to the lower bracket 62. The upper housing 13 and the lower housing 14 form mounting cavities 64 at both ends of the housing 1 along the length direction. The fan 2 is placed in the mounting cavity 64.

[0065] The lower bracket 62 is fixed to the lower housing 14, such as Figure 9As shown, mounting grooves 641 are provided at both ends of the lower bracket 62 along the length of the housing 1. The fan 2 is placed in the mounting groove 641 and connected to the lower bracket 62. The sidewall of the mounting groove 641 extends from the lower bracket 62 to the upper bracket 61, and is open on the side near the cooling component 4 to form the air outlet side 21 of the fan 2. Baffles 65 are provided on both sides of the air outlet side 21, pointing from the air outlet side 21 of the fan 2 to the cooling component 4. An isolation plate 63 is provided between the two baffles 65. A second channel 17 is formed between the lower bracket 62, the isolation plate 63 and the two baffles 65. A first channel 16 is formed between the upper bracket 61, the isolation plate 63 and the two baffles 65. The cooling component 4 is embedded in the lower bracket 62. The heat dissipation component 3, the heat conduction component 5, etc. are fixedly connected to the lower bracket 62 by bolts and other fasteners. The upper bracket 61 is fixedly connected to the lower bracket 62 to form an upper cavity and a lower cavity. The mounting groove 641 and the upper bracket 61 form a mounting cavity 64. An opening is provided on the upper bracket 61 at the position corresponding to the air inlet 10 and the heat dissipation port 12, so as to connect the air inlet 10 and the mounting cavity 64, and connect the heat dissipation port 12 and the upper cavity through the opening, so as to ensure that the airflow can flow normally along the airflow path in the neck part 101. In this embodiment, a bracket 6 is installed inside the housing 1 to stably fix the fan 2, cooling component 4, heat sink 3, and cooling conductor 5 via an upper bracket 61 and a lower bracket 62. At the same time, the upper bracket 61 and the lower bracket 62 are fixedly connected, and the two baffles 65 and the isolation plate 63 ensure that the airflow from the outlet side 21 of the fan 2 flows stably to the heat sink 3 and the cooling conductor 5. This achieves a balance between efficient heat dissipation of the heat sink 3 and stable blowing of cool air onto the back of the neck from the air outlet 11, preventing hot air in the upper cavity from flowing back to the cooling zone in the lower cavity. The baffles 65 and the isolation plate 63 prevent the airflow from the outlet side 21 from scattering, ensuring that the airflow can accurately flow to the cooling conductor 5 and the heat sink 3.

[0066] In another implementation of this embodiment, both the upper housing 13 and the lower housing 14 are provided with air inlets 10. The air inlet sides 22 of the fan 2 are on both sides of the fan's axial direction. The air inlet side 22 near the upper housing 13 is connected to the air inlet 10 of the upper housing 13, and the air inlet side 22 near the lower housing 14 is connected to the air inlet 10 of the lower housing 14, realizing air intake from both sides of the fan 2 and increasing the airflow rate discharged from the air outlet side 21. The air inlet 10 and the air outlet on the lower housing 14 are spaced apart to prevent the cold air flowing out of the air outlet 11 from entering the mounting cavity 64 through the air inlet 10. The air inlets 10 of the upper housing 13 and the lower housing 14 are connected to the mounting cavity 64, increasing the airflow rate in the mounting cavity 64 and ensuring that the airflow rate from the air outlet side 21 to the heat sink 3 and the cooling conductor 5 is sufficiently large.
