[0026] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings.

[0029] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0030] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] like Figure 1 As shown, the utility model provides a temperature conductor 2, which can be a radiator or a heat dissipation or cooling device arranged on other equipment that needs to conduct temperature. The temperature conductor 2 conducts temperature through fins 3. The temperature conductor 2 in the embodiment of the utility model includes at least two fins 3. Among them, at least one through groove 4 is arranged on the fin 3, and an airflow channel is formed between two adjacent fins 3; at least one spoiler 6 is arranged in the airflow channel, and the formation of the airflow boundary layer is continuously destroyed by arranging the spoiler 6 in the airflow channel.

[0033] The through slot 4 is a through hole structure that runs through the two sides of the fin 3, and its shape can be circular, square, triangular, etc., and the utility model does not make specific restrictions. In a specific implementation, the through slot 4 can be a square through hole. The through slot 4 is provided so that the gas between two adjacent air flow channels can flow. A plurality of through slots 4 can be distributed along the length direction on a fin 3.

[0034] Among them, the through slots 4 on the same fin 3 include multiple ones, and the arrangement direction thereof is arranged along the length direction (X direction). The spoiler 6 on each fin 3 can be set on the inner side of the through slot 4, and the position and number of the through slots 4 on each fin 3 are the same. The spoiler 6 is fixedly mounted on the fin 3. In this embodiment, the temperature conductor 2 is used in conjunction with a power unit that can generate wind force, and the heat or cold on the fin 3 is taken away by the wind force. In this process, the wind force forms an airflow channel between the fins 3. The spoiler 6 in the airflow channel will change the direction of part of the airflow, disrupt the airflow in the channel, continuously destroy the formation of the airflow boundary layer, and enhance the heat exchange efficiency of the airflow. In a specific implementation, the number of through slots 4 on each fin 3 may be different, and the size is not specifically limited. The spoiler 6 is fixedly connected to the fin 3. Due to the different number of through slots 4 on different fins 3, the heat dissipation performance of each fin 3 is different, and the airflow channel pressure between the fins 3 is different. The wind force between adjacent airflow channels can interact through the through slots 4, thereby disrupting the airflow in the channel, continuously destroying the formation of the airflow boundary layer, and enhancing the heat exchange efficiency of the airflow. In this embodiment, the through slots 4 and the spoiler 6 jointly achieve the effect of destroying the formation of the airflow boundary. In another specific implementation, the position of the through slots 4 on each fin 3 is different, and the spoiler 6 is fixedly connected to the fin 3. Similarly, when the position of the through slots 4 on each fin 3 is different, the airflow pressure of a section of the airflow channel is different from that of the adjacent airflow channel. The two adjacent airflow channels usually exchange gas to destroy the formation of the airflow boundary and enhance the heat exchange efficiency of the airflow.

[0035] Wherein, the number of spoilers 6 can be multiple, and they can be arranged on at least one side of the fin 3 and / or on the substrate, and their arrangement direction is arranged along the length direction (X direction). Wherein, the spoiler 6 is arranged on the fin 3, which will change part of the airflow in the airflow channel to flow along the extension direction of the spoiler 6. The spoiler 6 can be arranged on the same side of the same fin 3, or on both sides. Wherein, the substrate is a component at the bottom of the temperature conductor 2 for supporting the fin 3. In a specific implementation, when multiple spoilers 6 are arranged on the same side of the fin 3, the interval between them is not fixed, and the multiple spoilers 6 are not on the same straight line. In another specific implementation, when multiple spoilers 6 are arranged on both sides of the fin 3, the spoilers 6 on the two sides can be symmetrically arranged or asymmetrical, and the embodiment of the utility model does not make specific restrictions. In another specific implementation, the angle between the spoiler 6 and the fin 3 is 20°-30°. When the spacing between the fins 3 is constant, as the angle of the spoiler 6 increases, the amount of air flowing through the fins 3 decreases, while the amount of air flowing along the spoiler 6 increases, resulting in enhanced heat exchange. However, at the same time, the influence area of ​​the thermal wake zone behind the spoiler 6 will also change, resulting in weakened heat exchange. When the angle between the spoiler 6 and the fin 3 is 20°-30°, the thermal wake zone can be effectively disrupted, reducing the impact of the thermal wake zone on heat exchange.

[0036] Wherein, the spoilers 6 in an airflow channel may be the same or different in position and quantity, and the setting direction may also be the same or different. Wherein, in a specific implementation, the extension direction of the spoilers 6 in the same airflow channel may be sequentially ordered, such as when the extension direction of the spoilers 6 is along the X direction, a plurality of spoilers 6 are arranged in sequence along the positive X direction and the reverse X direction. In another specific implementation, the extension direction of some spoilers 6 distributed along the direction of the fin 3 in an airflow channel is opposite to the direction of the remaining spoilers 6; wherein, the spoilers 6 may be divided into two groups, one group of spoilers 6 extending in the positive X direction, and the other group of spoilers 6 extending in the reverse X direction, and the two groups of spoilers 6 are respectively arranged at both ends of the fin 3 or the substrate. In another specific implementation, the spoilers 6 may be arranged on the fin 3 or the substrate, and the setting direction of the spoilers 6 in the same airflow channel may be disordered, for example, a spoiler 6 is first set to extend in the positive X direction, and then two spoilers 6 are set to extend in the reverse X direction, and so on.

[0037] Among them, Figure 1 and Figure 2As shown, the spoiler 6 is a sheet-like structure, and the sheet-like structure is at a preset angle with the side. The spoiler 6 can be a sheet-like structure such as a wave-shaped, rectangular, triangular, or diamond-shaped structure. It needs to meet the airflow to achieve the diversion effect, and the material of the spoiler 6 is not required, as long as it can maintain a stable shape. One side of the sheet-like structure is set on the side of the fin 3, wherein the spoiler 6 of the sheet-like structure can be set near the through slot 4, or it can be set separately from the through slot 4. Among them, as Figure 3 and Figure 4 As shown, in a specific implementation, the spoiler 6 is a rectangular structure, and one side of the spoiler 6 is arranged at the inner edge of the through slot 4 to form a window structure with the through slot 4. The spoiler 6 is located within the projection range of the through slot 4 to form a window structure with the through slot 4, that is, the spoiler 6 is torn from the body of the fin 3, so that it is more convenient to process and form the spoiler 6 on the fin 3. Since the pressure of the part of the airflow in the airflow channel located at the spoiler 6 is uneven with that of the adjacent airflow channel, and the through slot 4 is located at the spoiler 6, the airflow in the airflow channel flows to the adjacent airflow channel, thereby destroying the formation of the airflow boundary layer.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment of the utility model, the shape of the spoiler 6 can also be an irregular shape. In this embodiment, the spoiler 6 includes a connecting piece 602 and a spoiler 601 that is not in the same plane as the connecting piece 602; one end of the connecting piece 602 is connected to the spoiler 601; the other end of the connecting piece 602 is fixedly connected to the side of the fin 3, so that; the connecting piece 602 is inclined relative to the side of the fin 3, and the spoiler 601 is parallel to the side of the fin 3 or inclined outward relative to the side of the fin 3.

[0039] Wherein, the connecting piece 602 and the spoiler 601 are both rectangular, and the first side of the spoiler 601 is connected to the second side of the connecting piece 602, so that the angle between the connecting piece 602 and the spoiler 601 is an obtuse angle. And the arrangement direction between the connecting piece 602 and the spoiler 601 is perpendicular to the length direction of the airflow channel, that is, the connecting piece 602 and the spoiler 601 are arranged along the width direction of the fin 3. In one implementation, one end of the connecting piece 602 is fixedly connected to the side of the fin 3, and the angle between the connecting piece 602 and the fin 3 can be 20°-30°, and the spoiler 601 is parallel to the side of the fin 3. After the airflow meets the spoiler 6, part of the airflow flows along the shape of the spoiler 6, thereby disrupting the airflow in the channel, so as to continuously destroy the formation of the airflow boundary layer and enhance the heat exchange efficiency of the airflow. In another implementation, one end of the connecting piece 602 is fixedly connected to the side of the fin 3. At this time, a certain inclination angle or direct verticality is provided between the spoiler 601 and the side of the fin 3, which can also achieve the effect of destroying the formation of the airflow boundary layer.

[0040] like Figure 5-Figure 7 As shown, the utility model also provides a neck-hanging air conditioner, including the above-mentioned temperature conductor. The neck-hanging air conditioner also includes an inner shell 7, an outer shell 5 and a bracket 8, wherein the bracket 8 is located between the outer shell 5 and the inner shell 7, and the bracket 8 is provided with a mounting groove for accommodating the refrigerator 1, so that the heating end of the refrigerator 1 faces the first accommodating cavity formed by the bracket 8 and the outer shell 5, and the cooling end of the refrigerator 1 faces the second accommodating cavity formed by the bracket 8 and the inner shell 7; the inner shell 7 is provided with a first air outlet 702 and a first air inlet 703, and the outer shell 5 is provided with a second air outlet 701 and a second air inlet 704.

[0041] Among them, the temperature conductor 2 is connected to the heating end and the cooling end of the refrigerator 1 by heat conduction, and the external air is guided to flow in the cold / hot air outlet and the cold / hot air inlet through the centrifugal fan. The refrigerator 1 is arranged in the installation groove on the bracket 8, so that the cooling end and the heating end of the refrigerator 1 are respectively located on the two sides of the bracket 8, and the structure of the bracket 8 matches the inner shell 7 and the outer shell 5, so as to separate the first accommodating cavity from the second accommodating cavity. Therefore, the heat dissipation duct and the cooling duct formed by the centrifugal fan and the two sides of the refrigerator 1 are completely isolated, thereby improving the efficiency of cooling and heat dissipation.

[0042] Among them, the outer shell 5 and the inner shell 7 are both unclosed annular structures, and the structural shape of the temperature conductor 2 matches the shape of the inner shell 7 and the outer shell 5. The inner shell 7 is arranged on the side close to the human skin, and the outer shell 5 is arranged on the side away from the human skin. The first air outlet 702 and the first air inlet 703 are arranged on the inner shell 7. In this embodiment, the first air outlet 702 is arranged on the upper part of the inner shell 7 so that the cold air blows toward the head of the human body, and the first air inlet 703 is arranged in the middle part of the inner shell 7. During the process of inhaling air, the outside air can help reduce the temperature at the neck. The second air outlet 701 and the second air inlet 704 are arranged on the outer shell 5 so that the hot air blown out is away from the human skin.
