Description
Technical Field
[0001] This utility model relates to the field of temperature regulation, and in particular to a cooling device. Background Technology
[0002] In daily life, to meet the cooling needs of people during outdoor activities and other living scenarios, a variety of cooling devices have emerged on the market, such as those that incorporate semiconductors for cooling within fans. To improve the cooling efficiency of fans, they are generally combined with both airflow and cooling functions, enabling fans to both blow air and provide cooling.
[0003] Currently, semiconductor fans generate a lot of heat when they are running, and usually require a dedicated cooling fan inside. This heat accumulates inside the neck fan and needs a dedicated air duct to exhaust it outwards. The air blowing part also needs a dedicated air duct to blow air onto the body to cool it down. Setting up multiple air ducts in a limited space will lead to poor heat dissipation and airflow efficiency. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a cooling device that can improve heat dissipation efficiency to achieve rapid cooling.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A cooling device includes a housing, which is bent to form a wearing space. The side of the housing closest to the wearing space is the inner side, and the side of the housing furthest from the wearing space is the outer side. The thickness direction of the housing is from the inner side to the outer side. A cooling component and a heat-conducting component are disposed inside the housing. The heat-conducting component is disposed on the inner side and exposed in the wearing space. The cold end of the cooling component is thermally connected to the heat-conducting component. A heat dissipation duct and a blowing duct are provided separately along the thickness direction inside the housing. A heat dissipation component is disposed in the heat dissipation duct and is thermally connected to the hot end of the cooling component. The heat dissipation duct has a heat dissipation port, and the blowing duct has a blowing port. A fan is disposed inside the housing. The air generated by the fan passes through the heat dissipation duct and the blowing duct and is blown out from the heat dissipation port and the blowing port.
[0007] As a further improvement to this solution, the heat dissipation vent and the air blowing vent are located on different sides of the housing.
[0008] As a further improvement to this solution, the heat dissipation vent is located on the outer side, and the heat dissipation duct extends through to the outer side of the housing and communicates with the heat dissipation vent.
[0009] As a further improvement to this solution, the housing is provided with an air guide plate, which divides the interior of the housing. The air duct on the side of the air guide plate near the cooling component is the heat dissipation air duct, and the air duct on the side of the air guide plate away from the cooling component forms the blowing air duct. The air guide plate is provided with a through hole, and a partition is provided on the side of the through hole near the blowing air duct. The partition surrounds the through hole and extends to the heat dissipation port to form an extension channel. The extension channel is connected to the heat dissipation air duct and the heat dissipation port.
[0010] As a further improvement to this solution, the heat sink includes a base plate and a plurality of fins disposed on the base plate. The base plate is thermally connected to the hot end of the cooling component. The fins are disposed on the side of the base plate away from the cooling component. Along the length direction of the fins, a baffle is provided inside the housing. The baffle is disposed on the end of the base plate away from the fan and guides the airflow passing through the fins to the heat dissipation port.
[0011] As a further improvement to this solution, the base plate is provided with fixing structures on opposite sides for fixing the heat sink. The fixing structures extend and fold away from the fins and are located outside the heat dissipation duct.
[0012] As a further improvement to this solution, the housing includes a first side and a second side opposite to each other, the first side and the second side being connected to the inner side and the outer side of the housing, respectively. The air guide plate is provided with an air duct plate on the side near the air blowing duct, the air duct plate dividing the air blowing duct into an upper air duct and a lower air duct. The first side of the housing is provided with an air blowing port connected to the upper air duct, and the second side of the housing is provided with an air blowing port connected to the lower air duct.
[0013] As a further improvement to this solution, the upper air duct and the lower air duct are spaced apart, and the heat dissipation air duct is located between the upper air duct and the lower air duct.
[0014] As a further improvement to this solution, the housing is provided with a vortex shell, which is located on one side of the air guide plate along the length direction of the housing. The fan is located inside the vortex shell. The vortex shell has two openings, which are spaced apart by the air duct plate. The two openings correspond to the upper air duct and the lower air duct, respectively.
[0015] As a further improvement to this solution, air inlets are provided on the inner side and the outer side, with the air inlet on the inner side penetrating the temperature-conducting component, and the fan being arranged opposite to the air inlet.
[0016] The beneficial effects of this invention are as follows: The housing is divided into three layers along its thickness direction, forming a cooling component, a heat dissipation duct, and a blowing duct. This allows the heat dissipation component to be made thinner, ensuring sufficient contact surface between the cooling component and the heat dissipation component. A larger contact area means a wider "entry point" for heat to enter the radiator, allowing the heat from the cooling component to diffuse more quickly and evenly throughout the entire radiator base. Simultaneously, it reduces the thermal resistance along the heat transfer path per unit area. Furthermore, the blowing duct, combined with the design of the airflow channel, increases heat dissipation efficiency within the limited space of the housing while simultaneously cooling the user through the airflow.

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0025] Reference Figures 1 to 5 This utility model provides a cooling device, including a housing 1. The housing 1 is bent to form a wearing space for a user to wear. The housing 1 has a length direction, a thickness direction, and a height direction, with the wearing space formed by bending along the length direction. The side of the housing 1 closest to the wearing space is the inner side, which is the side away from the wearing space when the user wears the device; the side of the housing 1 furthest from the wearing space is the outer side. The thickness direction of the housing 1 is from the inner side to the outer side. The housing 1 is designed to effectively accommodate internal components and provide a comfortable user experience.
[0026] The housing 1 contains a cooling component 3 and a heat-conducting component 2. The cooling component 3 is a device that utilizes the thermoelectric effect of semiconductor materials to achieve cooling, based on the Peltier effect. The heat-conducting component 2 is located inside the housing 1 and exposed in the wearing space. The cold end of the cooling component 3 is thermally connected to the heat-conducting component 2, facilitating direct contact with the wearer's skin for rapid heat conduction and cooling. A fan is also included inside the housing 1 to generate airflow for cooling the cooling component 3, while some airflow is directed directly at the user for further cooling.
[0027] The housing 1 contains a heat dissipation duct 101 and a blowing duct 102, which are separated from each other and are arranged side by side along the thickness direction. The heat dissipation duct 101 carries hot airflow for cooling the cooling component 3, while the blowing duct 102 carries ordinary airflow for direct cooling to the user. A fan generates airflow to propel the air through the heat dissipation duct 101 and the blowing duct 102. The two ducts, each with a different function, are separated to ensure independent and efficient airflow. Furthermore, to ensure the heat dissipation effect of the cooling component 3, a heat sink 4 is provided within the heat dissipation duct 101. The heat sink 4 is thermally connected to the hot end of the cooling component 3, quickly carrying away the heat generated by the cooling component 3 and preventing the internal temperature of the device from becoming too high. The heat dissipation duct 101 has a heat dissipation port 12, and the blowing duct 102 has a blowing port 11, allowing the airflow within the ducts to exit through the heat dissipation port 12 and the blowing port 11 respectively. The airflow blows through the heat sink 4 in the heat dissipation duct 101, carrying away the heat on the heat sink 4, and then exhausts it from the heat dissipation port 12 and the air outlet 11, ensuring the heat dissipation effect on the semiconductor cooling component 3.
[0028] The housing 1 is divided along its thickness into a three-layer structure: a cooling component 3, a heat dissipation duct 101, and a blowing duct 102. This ensures sufficient contact surface between the cooling component 3, the heat-conducting component 2, and the heat dissipation component 4. A larger contact area means a wider "entry point" for heat to enter the radiator, allowing the heat from the cooling component 3 to diffuse more quickly and evenly throughout the entire radiator base. Simultaneously, it reduces the thermal resistance along the heat transfer path per unit area. Furthermore, the blowing duct, combined with the design of the airflow channel, increases heat dissipation efficiency within the limited space of the housing 1 while simultaneously cooling the user through the airflow.
[0029] Preferably, the heat dissipation vent 12 and the air blowing vent 11 are located on different sides of the housing 1, so that the two air ducts blow air in different directions, avoiding the convergence and mixing of two airflows of different temperatures on the outside, and preventing the user from being affected by hot air when using the air blowing vent for cooling. Specifically, the heat dissipation vent 12 is located on the outside, and the heat dissipation air duct 101 extends through the housing 1 from the thickness direction to the outside and connects with the heat dissipation vent 12. The heat dissipation vent 12 is located away from the wearing space, so that heat is blown out in a direction away from the wearing space, preventing hot air from entering the wearing area and thus affecting the wearer's comfort.
[0030] To separate the interior of housing 1 into two distinct air ducts, an air guide plate 5 is installed inside housing 1. The air guide plate 5 is arranged along the length of housing 1, dividing the interior of housing 1 into two sides along its thickness. Specifically, the air duct on the side closer to the cooling component 3 forms a heat dissipation air duct 101, responsible for timely dissipation of heat generated during the cooling process. The air duct on the side away from the cooling component 3 forms a blowing air duct 102, used to blow the airflow generated by the fan to the outside to cool the user.
[0031] Furthermore, the air guide plate 5 is provided with a through hole 51, which communicates with the heat dissipation duct 101, allowing the airflow in the heat dissipation duct 101 to be blown out through the through hole 51, thereby improving the airflow direction of the hot air duct. The through hole 51 causes the hot air duct to blow towards the blowing duct 102. To avoid the airflow of the hot air duct and the airflow of the blowing duct 102 interfering with each other, a partition 52 is provided on the air guide plate 5. The partition 52 is located on the side close to the blowing duct 102 and surrounds the through hole 51, forming an extended channel. The extended channel extends towards the heat dissipation port 12 on the outside of the housing 1, connecting the heat dissipation duct 101 and the heat dissipation port 12. This ensures that the hot air in the heat dissipation duct 101 can be smoothly guided to the outside of the housing 1, effectively avoiding the cross-influence of hot air and the blowing duct 102, thereby improving the heat dissipation effect of the cooling device and effectively separating and guiding the hot and cold airflows.
[0032] Preferably, to increase the heat dissipation efficiency of the heat sink 4 and thus improve the cooling efficiency of the cooling component 3, the heat sink 4 includes a base plate and several fins disposed on the base plate. The base plate transfers the heat generated by the cooling component 3 to the fins, and the fins accelerate heat dissipation by increasing their surface area. The base plate covers the hot end of the cooling component 3, and the two are thermally connected. The fins are disposed on the side of the base plate away from the cooling component 3, allowing more heat to be released from the heat sink 4 into the heat dissipation duct 101 and then carried away by airflow.
[0033] To further optimize the airflow path, a baffle is provided inside the housing 1 along the length of the fins. The baffle guides the hot airflow passing over the fins. Located at the end of the bottom plate away from the fan, the baffle directs the airflow over the fins to the side of the heat dissipation vent 12, and after passing through the extension channel, it exits from the heat dissipation vent 12. The baffle ensures that hot air does not directly rush towards other areas inside the housing 1 besides the heat dissipation duct 101, but is guided to the heat dissipation vent 12. After passing over the fins, the airflow blows directly towards the baffle, which changes the direction of the airflow, causing the hot air to flow along a specific path. This ensures smooth flow of hot air from the heat dissipation duct 101 to the extension channel, further optimizing the overall efficiency of the cooling system.
[0034] Furthermore, the base plate of the heat sink 4 is provided with a fixing structure 41 for fixing the heat sink 4. The fixing structure 41 is fixedly connected to the temperature conducting element 2, and simultaneously clamps the cooling element 3 between the heat sink 4 and the temperature conducting element 2, thereby forming a tight fit between the heat sink 4, the cooling element 3, and the temperature conducting element 2. The fixing structure 41 is located on opposite sides of the base plate. To avoid the fixing structure 41 affecting the airflow path within the heat dissipation duct 101, the fixing structure 41 extends and folds away from the fins, so that the fixing structure 41 is located outside the heat dissipation duct 101, ensuring that the airflow is not obstructed, thereby improving the heat dissipation performance.
[0035] The housing 1 includes a first side and a second side, which are opposite to each other. Figure 5 The upper and lower sides shown, the first side and the second side are respectively connected to the inner and outer sides of the housing 1. The two sides of the first side are connected to the inner and outer sides of the housing 1, and the two sides of the second side are also connected to the inner and outer sides of the housing 1, so that the housing 1 forms a closed space.
[0036] To optimize airflow, the air guide plate 5 is provided with an air duct plate 53 on the side near the air blowing duct 102. The air duct plate 53 divides the air blowing duct 102 into an upper air duct 103 and a lower air duct 104. With this design, the upper and lower air ducts each undertake different airflow paths, which can achieve effective airflow delivery in different directions.
[0037] To further enhance airflow guidance and control, the housing 1 is equipped with air duct plates 53. These air duct plates 53 structurally serve to isolate and guide airflow, allowing it to pass through each air duct more evenly and orderly, thus avoiding irregularities and waste. The first side of the housing 1 has an air outlet 11 connected to the upper air duct 103, and the second side of the housing 1 has an air outlet 11 connected to the lower air duct 104. Air will flow out from the upper and lower air ducts 104 respectively, thereby achieving airflow diffusion in two different directions.
[0038] The upper air duct 103 and the lower air duct 104 are spaced apart and separated from each other by the air duct plate 53, avoiding cross-interference of airflow between the two air ducts. The heat dissipation air duct 101 is set between the upper air duct 103 and the lower air duct 104. This avoids interference between the heat dissipation air duct 101 and the blowing air duct 102, and avoids the negative impact of heat on airflow.
[0039] The housing 1 is equipped with a vortex 6, which is located on one side of the air guide plate 5 along the length of the housing 1. A fan is installed inside the vortex 6 and drives the airflow by rotation. The vortex 6 has two openings, which are spaced apart by an air duct plate 53. The function of the air guide plate 5 is to separate the airflow paths between the two openings. The two openings correspond to the upper air duct 103 and the lower air duct 104, respectively, effectively avoiding mutual interference between airflows and ensuring that each airflow maintains an independent and smooth flow path.
[0040] Furthermore, the vortex shell 6 includes vortex tongues, with each of the two openings corresponding to a vortex tongue. The main function of the vortex tongues is to guide and control the direction of airflow. A transition section is provided on the side of the opening away from the vortex tongues, connecting the vortex tongues and the air guide plate 5. Through a reasonable transition design, the airflow can gradually adapt to the shape of the air duct of the air guide plate 5, thereby avoiding sharp turns and airflow turbulence.
[0041] The fan needs to draw in airflow from the air inlet 13 and blow it into the housing 1. Air inlets 13 are provided on both the inner and outer sides of the housing 1, corresponding to the two sides of the fan. The two air inlets 13 effectively increase the air intake and improve the ventilation efficiency of the system.
[0042] Meanwhile, the air inlet 13 located on the inner side penetrates the temperature-conducting element 2, allowing external airflow to pass through the temperature-conducting element 2 before entering the housing 1. Since the temperature-conducting element 2 is thermally connected to the cold end of the cooling element 3, the airflow can be further cooled after passing through the temperature-conducting element 2 before entering the housing 1 for heat dissipation or being blown out, achieving a good cooling effect and further improving the heat dissipation efficiency. Furthermore, to prevent the user from blocking the air inlet 13 while wearing the cooling device, the air inlet 13 of the temperature-conducting element 2 is located at the end along its length, and the airflow generated at the air inlet 13 will make the user feel cooler and more breathable during use.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model.
