[0002] With the increasing demands for quality of life and the growing need for portable cooling devices, wearable temperature control devices have emerged as a new type of personal cooling equipment. These devices, with their ease of use and ability to provide localized cooling anytime, anywhere, have garnered widespread attention in outdoor activities, commuting, and other scenarios.

[0003] These types of devices typically use thermoelectric coolers as the core cooling component. However, thermoelectric coolers have limited cooling capacity and generate heat during the cooling process. If the heat generated at the hot end of the thermoelectric cooler cannot be dissipated quickly, it will affect the cooling effect at the cold end of the thermoelectric cooler. Therefore, improving the cooling efficiency of thermoelectric coolers has become an urgent problem to be solved. Utility Model Content

Similarly, the surface of the second heat sink facing the heat dissipation outlet is recessed to form a plurality of spaced-apart second heat dissipation ducts, which also guide the airflow generated by the adjacent first fan to the air guide structure.

[0009] In an embodiment of this utility model, the temperature control component further includes a cooler, which is located on the side of the cooling component near the wearable space and is thermally connected to the cold end of the cooling component. The neckband is provided with a cold air outlet on the side near the wearable space, which is provided corresponding to the cooler.

[0010] In an embodiment of this utility model, the surface of the cooler facing the wearable space is recessed to form a plurality of spaced-apart cold air channels, and the two ends of the cold air channels are respectively directed toward the two first fans.

[0011] In an embodiment of this utility model, the cold air channel includes a first sub-air duct and a second sub-air duct that are staggered with each other. The air inlet side of the first sub-air duct faces the air outlet side of one of the adjacent first fans, and the air inlet side of the second sub-air duct faces the air outlet side of another adjacent first fan.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, and bottom) in this utility model embodiment are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly. Furthermore, the term "vertical" in the utility model embodiments and claims refers to an angle of 90° between two components or a deviation of -5° to +5°, and the term "parallel" refers to an angle of 0° between two components or a deviation of -5° to +5°.

[0034] In this embodiment of the invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0035] Reference Figure 1, Figure 2 and Figure 7 As shown in the figure, a wearable temperature regulating device 1 provided by this utility model embodiment includes: a housing 10, including a neck strap 110 and handles 112 located at both ends of the neck strap 110, the neck strap 110 and the two handles 112 forming a wearing space 101. The wearing space 101 is used to wear around the user's neck. The housing 10 can be made of, for example, a plastic material with good ductility, which can deform to a certain extent when worn to adapt to different users.

[0036] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the wearable temperature-regulating device 1 includes a temperature-regulating component 20, located within the neckband 110. The temperature-regulating component 20 includes a cooling element 202 and a heat sink 204. The heat sink 204 is located on the side of the neckband 110 away from the wearing space 101 and is thermally connected to the hot end of the cooling element 202. A heat dissipation outlet 108 is provided on the side of the neckband 110 away from the wearing space 101, corresponding to the heat sink 204. The side of the cooling element 202 closest to the wearing space 101 is the cold end, and the cold energy generated at the cold end is transferred to the cooler 206, which then transfers the cold energy to the user's skin to generate a cooling sensation. The side of the cooling element 202 away from the wearing space 101 is the hot end, and the heat sink 204 dissipates the heat generated at the hot end outside the housing 10 for heat dissipation. The cooling element 202 can be, for example, a sheet-like semiconductor cooling chip, and the cooler 206 and heat sink 204 can be made of copper or aluminum, which have good thermal conductivity. The heat dissipation outlet 108 is located on the side of the housing 10 away from the wearable space 101 to prevent hot airflow from blowing towards the user.

[0037] Reference Figure 3 and Figure 5As shown, the wearable temperature control device 1 also includes two first fans 302, which are located inside the housing 10. One first fan 302 is located on the side of the cooling component 202 facing one of the handle portions 112, and the other first fan 302 is located on the side of the cooling component 202 facing the other handle portion 112. The air outlet sides of the two first fans 302 are respectively facing the heat sink 204. A guide structure 1141 is provided in the neckband 110 corresponding to the heat dissipation outlet 108. The guide structure 1141 divides the heat sink 204 into two parts that are close to the two first fans 302. The airflow generated by each first fan 302 blows towards the adjacent part of the heat sink 204 and is guided to the heat dissipation outlet 108 by the guide structure 1141. Specifically, since the two first fans 302 are located on opposite sides of the cooling component 202 and blow air towards the heat sink 204 respectively, the air guide structure 1141 is set at the heat dissipation outlet 108 to isolate the airflow blown out by the two first fans 302, avoiding turbulence caused by collision at the heat sink 204, thus preventing noise. At the same time, it can also quickly guide hot air to the outside, improving heat dissipation efficiency.

[0038] Reference Figure 10 and Figure 11 As shown, two first fans 302 simultaneously blow air onto the heat sink 204, improving the heat dissipation efficiency of the hot end of the cooling component 202, thereby improving the cooling efficiency of the cold end of the cooling component 202. The first fan 302 includes a partition 3023 and a fan 3024. The partition 3023 forms a heat dissipation channel 12 and a cooling channel 14 on opposite sides of the fan 3024 along the thickness direction of the housing 10. Part of the fan 3024 is located within the heat dissipation channel 12, and part is located within the cooling channel 14. For example, the partition 3023 can be a double-layered volute, forming two non-interfering heat dissipation channels 12 and cooling channels 14 with the fan 3024. The first fan 302 includes a first air outlet 3021 and a second air outlet 3022. The first air outlet 3021 is connected to the heat dissipation channel 12, and the second air outlet 3022 is connected to the cooling channel 14.

[0039] The temperature control assembly 20 also includes a cooler 206 connected to the cold end of the cooling component 202. The fan 3024 drives airflow from the second air outlet 3022 into the cooler duct 14. Within the cooler duct 14, the airflow exchanges heat with the cooler 206, which lowers the airflow temperature. The cooled airflow is then blown towards the user, lowering the ambient temperature and creating a cooling sensation. The hot end of the cooling component 202 continuously generates heat. Simultaneously, the fan 3024 drives airflow from the first air outlet 3021 into the heat dissipation duct 12. Within the heat dissipation duct 12, the airflow exchanges heat with the radiator 204, carrying away heat from the radiator 204 and effectively dissipating heat from the cooling component 202, ensuring a cooling effect.

[0040] Reference Figure 1 , Figure 2 and Figure 3 As shown, the handle portion 112 also includes two second fans 304, each located at one end of the handle portion 112 away from the neckband portion 110. Each second fan 304 is a single-partition fan, forming an airflow duct 3048 within the handle portion 112. The second fan of the second fan 304 is located within the airflow duct 3048. The second fan 304 includes a third air inlet 3043, located on the side of the handle portion 112 away from the wearing space 101, and is connected to the airflow duct 3048. The handle portion 112 also includes a third air outlet 3045, located within the handle portion 112 containing the second fan 304 and close to the neckband portion 110, and is also connected to the airflow duct 3048. The second fan 304 draws in air through two third air inlets 3043, and blows it out through the third air outlet 3045 via the air duct 3048, making contact with the user's skin. The air duct 3048 does not contain a temperature control component 20; it is used to create a gentle breeze circulation around the user's neck, providing a cooling sensation. The other second fan 304 is configured similarly and will not be described in detail here.

[0041] In the embodiments of this utility model, reference is made to Figure 4 and Figure 12 As shown, the radiator 204 includes a first heat sink 2040 and a second heat sink 2041 arranged at intervals. The first heat sink 2040 is located near one of the first fans 302, and the second heat sink 2041 is located near the other first fan 302. An air guide structure 1141 is located between the first heat sink 2040 and the second heat sink 2041. The airflow generated by one of the first fans 302 blows towards the first heat sink 2040 and is then guided by the air guide structure 1141 to the heat dissipation outlet 108. The airflow generated by the other first fan 302 blows towards the second heat sink 2041 and is then guided by the air guide structure 1141 to the heat dissipation outlet 108. In this embodiment, the first heat sink 2040 and the second heat sink 2041 are two independently arranged components. The air guide structure 1141 can be arranged on the first heat sink 2040 or the second heat sink 2041, or the air guide structure 1141 can be a separate component independent of the first heat sink 2040 and the second heat sink 2041. Of course, in other embodiments, the air guide structure 1141 may also be integrated with the first heat sink 2040 and the second heat sink 2041.

[0042] Specifically, the housing 10 includes a mounting bracket 114, an air guide structure 1141 disposed in the middle of the mounting bracket 114, and a heat sink 204 mounted on the mounting bracket 114. The air guide structure 1141 is isolated between the first heat sink 2040 and the second heat sink 2041. The mounting bracket 114 isolates the first heat sink 2040 and the second heat sink 2041, preventing mutual interference of heat between the two heat sinks. At the same time, the air guide structure 1141 blocks the airflow between adjacent first heat sinks 2040 and second heat sinks 2041, preventing airflow from colliding with the first heat sink 2040 and the second heat sink 2041. Furthermore, each heat sink can complete more heat dissipation cycles within a fixed time, thus shortening the overall heat dissipation cycle time and effectively improving the overall heat dissipation efficiency.

[0043] In the embodiments of this utility model, reference is made to Figure 12 As shown, the air guiding structure 1141 includes a first air guiding surface 1142 and a second air guiding surface 1144. The first air guiding surface 1142 faces the first heat sink 2040, and the second air guiding surface 1144 faces the second heat sink 2041. The first air guiding surface 1142 and the second air guiding surface 1144 are arranged in an arc shape. The arc-shaped arrangement of the first air guiding surface 1142 and the second air guiding surface 1144 is more conducive to gently guiding the airflow to the heat dissipation outlet 108 and avoiding noise generation.

[0044] In the embodiments of this utility model, reference is made to Figure 5 and Figure 7 As shown, the surface of the first heat sink 2040 facing the heat dissipation outlet 108 is recessed to form several spaced first heat dissipation air ducts 121. The first heat dissipation air ducts 121 guide the airflow generated by the adjacent first fan 302 to the air guide structure 1141. The surface of the second heat sink 2041 facing the heat dissipation outlet 108 is recessed to form several spaced second heat dissipation air ducts 122. The second heat dissipation air ducts 122 guide the airflow generated by the adjacent first fan 302 to the air guide structure 1141. Both the first heat dissipation air ducts 121 and the second heat dissipation air ducts 122 are connected to the heat dissipation air duct 12. Through the first heat dissipation air ducts 121 and the second heat dissipation air ducts 122, the airflow generated by the two first fans 302 is better guided to the air guide structure 1141.

[0045] Specifically, the first heat sink 2040 and the second heat sink 2041 include a heat sink 2042 and multiple heat sink fins 2044. The heat sink 2042 is connected to the side of the cooling component 202 away from the wearable space 101. The multiple heat sink fins 2044 are located on the side of the heat sink 2042 away from the cooling component 202. The multiple heat sink fins 2044 are arranged at intervals, and a first heat dissipation channel 121 and a second heat dissipation channel 122 are formed between adjacent heat sink fins 2044. The cooling component 202 transfers the generated heat to the heat sink 2042, and the heat sink 2042 then transfers the heat to the multiple heat sink fins 2044 through the first heat dissipation channel 121 and the second heat dissipation channel 122, thereby increasing the contact area between the airflow and the heat sink 204 and improving the efficiency of heat exchange.

[0046] In the embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, the temperature control component 20 also includes a cooler 206. The cooler 206 is located on the side of the cooling component 202 near the wearing space 101 and is heat-conducted to the cold end of the cooling component 202. The neckband 110 is provided with a cold air outlet 106 on the side near the wearing space 101. The cold air outlet 106 is set corresponding to the cooler 206. Part of the airflow generated by each first fan 302 blows towards the radiator 204, and the other part blows towards the cooler 206 and flows out from the cold air outlet 106.

[0047] Reference Figure 3 , Figure 5 and Figure 6 As shown, the fan 3024 of the first fan 302 is partially located within the heat dissipation duct 12 and partially within the cooling duct 14. The partition 3023 allows the first fan 302 to simultaneously generate two independent airflows for both airflow and heat dissipation. Each first fan 302 can simultaneously dissipate heat and blow air onto both sides of the temperature control component 20, eliminating the need for additional cooling fans that would occupy space within the housing 10. This achieves both airflow and heat dissipation within a limited space. Furthermore, the space saved from installing an additional cooling fan can be used to enlarge the size of the heat sink 204. A larger heat sink 204 allows for an increase in the number of heat dissipation fins 2044, significantly increasing the heat dissipation area and enabling rapid heat transfer to the outside. The use of the first fan 302 to simultaneously generate two airflows within a limited space not only reduces the number of fans required, lowering manufacturing costs, but also further improves heat dissipation efficiency and ensures effective cooling.

[0048] Reference Figure 2 and Figure 3As shown, the cold air outlet 106 is located on the side of the cooler 206 near the wearable space 101, and is connected to the cooling duct 14. The cold air outlet 106 may be, for example, a plurality of vertical strip-shaped through holes arranged at intervals. The lengths of the vertical strip-shaped through holes may be the same or different. The cold air outlet 106 is adjacent to the back of the neck, which can quickly reduce the local temperature of the user's neck, significantly improving the efficiency of cold air transfer and allowing the user to feel cool more quickly, effectively enhancing the cooling sensation and preventing the cold air from being absorbed by the surrounding ambient temperature due to a long transmission path.

[0049] Reference Figure 4 As shown, in some embodiments, the contact area between the heat sink 204 and the cooling component 202 is larger than the contact area between the cooler 206 and the cooling component 202. Specifically, the heat sink 204 includes a heat dissipation plate 2042, which connects to the side of the cooling component 202 away from the wearing space 101. The cooler 206 includes a cooler plate 2062, which connects to the side of the cooling component 202 close to the wearing space 101. In this embodiment, the size of the heat dissipation plate 2042 is larger than the size of the cooler plate 2062. With the same contact area of ​​the cooling component 202, the larger heat dissipation plate 2042 can distribute heat over a larger area, increasing the heat dissipation area and effectively improving heat dissipation efficiency. When the cooling capacity of the cooling component 202 is limited, the increased heat dissipation area can reduce the temperature of the cooling component 202 more quickly, helping to improve the energy efficiency ratio of the cooling component 202, enabling the cooling system to provide better cooling effect with the same energy consumption, while extending the service life of the cooling component 202.

[0050] In the embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, the surface of the cooler 206 facing the wearable space 101 is recessed to form several spaced-apart cold air channels 140, with both ends of the cold air channels 140 facing the two first fans 302 respectively. The cooler 206 includes a cooler plate 2062 and multiple cooler fins 2064. The cooler plate 2062 is connected to the side of the cooling component 202 near the wearable space 101, and the multiple cooler fins 2064 are located on the side of the cooler plate 2062 away from the cooling component 202. The multiple cooler fins 2064 are spaced apart, and a cold air channel 140 is formed between two adjacent cooler fins 2064. The cold air channel 140 is connected to the cooler air duct 14. The cooling component 202 transfers the generated cooling energy to the cooler plate 2062, and the cooler plate 2062 transfers the cooling energy to the multiple cooler fins 2064 through the cold air channel 140, thereby increasing the contact area between the airflow and the cooler 206 and enhancing the cooling effect.

[0051] In some embodiments, refer to Figure 4As shown, the area of ​​a single heat dissipation fin 2044 is larger than that of a single heat conduction fin 2064. The larger area of ​​a single heat dissipation fin 2044 provides a larger heat dissipation surface area and a larger contact area with airflow, accelerating the conduction and dissipation of heat, thereby effectively improving heat dissipation efficiency.

[0052] In some embodiments, refer to Figure 1 , Figure 5 , Figure 7 and Figure 12 As shown, the housing 10 includes a neck section 110 and handle sections 112 respectively connected to both ends of the neck section 110. The temperature control component 20 is located in the middle of the neck section 110, and the width of the middle part of the neck section 110 is greater than the width of the ends of the neck section 110. The housing 10 extends outward from the middle part of the neck section 110, making the usable area of ​​the temperature control component 20 larger. In this embodiment, the size of the radiator 204 is enlarged, increasing the contact area with airflow, allowing heat to be transferred from the radiator 204 to the outside air more quickly, thus accelerating the heat dissipation speed.

[0053] In the embodiments of this utility model, reference is made to Figure 6 and Figure 8 As shown, the cold air duct 140 includes a first sub-duct 141 and a second sub-duct 142 that are staggered with each other. The air inlet side of the first sub-duct 141 faces the air outlet side of one of the adjacent first fans 302, and the air inlet side of the second sub-duct 142 faces the air outlet side of the other adjacent first fan 302. The airflow from the second air outlet 3022 of one of the first fans 302 passes through the first sub-duct 141, and the airflow from the second air outlet 3022 of the other first fan 302 passes through the second sub-duct 142. The paths of the multiple cold air ducts 140 in the first sub-duct 141 and the second sub-duct 142 are staggered to avoid the collision and turbulence of the airflow from the two first fans 302.

[0054] In the embodiments of this utility model, reference is made to Figure 6 , Figure 8 and Figure 9As shown, a first baffle plate 1130 is provided on the air outlet side of the housing 10 corresponding to the first sub-air duct 141. The first baffle plate 1130 is used to guide the airflow of the first sub-air duct 141 to the cold air outlet 106. A second baffle plate 1131 is provided on the air outlet side of the housing 10 corresponding to the second sub-air duct 142. The second baffle plate 1131 is used to guide the airflow of the second sub-air duct 142 to the cold air outlet 106. A clearance portion 20611 is provided on the cooling plate 2062. The clearance portion 20611 is located on the air outlet side of the first sub-air duct 141 and the second sub-air duct 142. The first baffle plate 1130 and the second baffle plate 1131 are located in the clearance portion 20611. Airflow from the second air outlet 3022 flows through the cold air channel 140 and forms cold air in the cooler 206. After passing through the cold air outlet 106, the flow direction of the cold air is changed by the first baffle 1130 and the second baffle 1131, guiding it back and passing through the cold air outlet 106 again. The first baffle 1130 and the second baffle 1131 better guide the cold air to the cold air outlet 106. The cold air passes through the cold air outlet 106 twice in the first sub-air channel 141 and the second sub-air channel 142, prolonging the contact time between the cold air and the area near the cold air outlet 106. This allows more cold air to be transferred to the wearing space 101 in the same amount of time, increasing the amount of cold air directly acting on the user and thus significantly enhancing the user's cooling sensation.

[0055] In the embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, each of the first fans 302 has an air inlet 102 on the side of the housing 10 facing the wearable space 101. Both air inlets 102 and the cold air outlet 106 are located on the side of the housing 10 facing the wearable space 101, with the two air inlets 102 positioned on either side of the cold air outlet 106. Part of the cold air blown out of the cold air outlet 106 dissipates after passing through the user's skin, while the remaining cold air is drawn into the cooling duct 14 by the air inlets 102 located on either side of the cold air outlet 106 to achieve the next cooling cycle. Recycling and reusing a portion of the cold air from the cold air outlet 106 reduces the additional cooling energy required to achieve the same cooling effect. Under the premise of achieving the same cooling effect, this reduces overall energy consumption, improves cooling efficiency, and enhances the cooling sensation.

[0056] Reference Figure 1 and Figure 3As shown, the side surface of the housing 10 away from the wearable space 101 is also provided with an air inlet 102 corresponding to each of the first fans 302. The two air inlets 102 are respectively located at both ends of the heat sink 204. The heat dissipation outlet 108 is arranged adjacent to the air inlets 102, which greatly shortens the distance between each air inlet 102 and the heat dissipation outlet 108, making the time for the airflow to complete a heat dissipation cycle shorter. In a unit of time, more airflow can participate in the heat dissipation cycle, and the heat generated by the heat sink 204 can be removed more quickly, thereby significantly improving the heat dissipation efficiency. The two air inlets 102 of the first fan 302 are located on opposite sides of it to prevent the hot airflow after heat exchange by the heat sink 204 from being sucked in by the air inlets 102 located close to the wearable space 101, thus increasing the load on the cooling component 202.

[0057] In the embodiments of this utility model, reference is made to Figure 2 As shown, the housing 10 has a plurality of protrusions 116 on the side surface facing the wearing space 101, and the plurality of protrusions 116 are spaced apart at the cold air outlet 106 and the air inlet 102. When the user uses the wearable temperature regulating device 1, the plurality of protrusions 116 can effectively prevent the user's skin from coming into contact with or blocking the cold air outlet and the air inlet, so that the airflow can enter and exit the device without obstruction.

[0058] In the embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, the neckband 110 and the two handles 112 form a C-shape. There are two cooling components 202, arranged adjacent to each other, forming an angle greater than 90° and less than 180° on the side facing the wearing space 101. This angle between the two cooling components 202 better suits the C-shaped housing, facilitating the airflow generated by each first fan 302 to be directed towards the heat sink 204. The two cooling components 202 are arranged along the curvature of the housing 10 to form a first heat sink 2040 and a second heat sink 2041, effectively increasing the number of heat dissipation fins 2044 within the limited space of the housing 10, thereby increasing the contact area with the airflow. A larger contact area allows more heat to be transferred from the heat dissipation fins 2044 to the external environment, accelerating heat dissipation.

Provided that the technical features do not conflict, the structure is not contradictory, and the inventive purpose of this utility model is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.
