Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology, specifically, it relates to a palm heat sink. Background Technology

[0002] Excessive sweating and overheating of the palms are common problems in daily life and work, causing many inconveniences. From making touchscreens unresponsive and phones slippery when holding electronic devices, to interfering with precision in delicate tasks like painting and handicrafts, sweat negatively impacts hand comfort and the convenience and accuracy of various operations. To address these issues, the market has seen the emergence of chemical antiperspirants, physical sweat-absorbing devices, and localized cooling products such as miniature cooling fans.

[0003] In practical use, it has been found that existing palm cooling and hand sweat removal devices cannot simultaneously meet the needs of cooling and sweat removal. Multiple devices are required, which creates a conflict between energy efficiency and portability. Semiconductor cooling devices have high power consumption, short battery life, and large size. Cold compresses need to be replaced frequently. Ordinary fans lack targeted airflow design, making it difficult to concentrate airflow on the palms, resulting in low cooling efficiency. They also cannot adjust the speed according to the degree of hand sweat, making it difficult to meet different scenarios.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0006] A palm heat sink includes a main body in the shape of a dumbbell. An upper shell and a lower shell are respectively installed at both ends of the main body. An active heat dissipation unit for cooling the palm is installed at the lower end of the main body.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] Example 1:

[0025] like Figures 1 to 6 As shown, a palm heat sink includes a main body 1, which is dumbbell-shaped. An upper shell 2 and a lower shell 3 are respectively installed at both ends of the main body 1. An active heat dissipation unit for cooling the palm is installed at the lower end of the main body 1. A control circuit board 5 for controlling the operation of the active heat dissipation unit and a battery 8 for powering the active heat dissipation unit are installed at the upper end of the main body 1. A plurality of first air outlets 13 and a plurality of second air outlets 14 are opened on the main body 1, and a plurality of air inlets 12 are opened on the lower shell 3. In this configuration, the outer shell 1 is dumbbell-shaped and serves as the main frame of the entire heat sink, supporting and protecting the internal components. Its shape is designed to conform to ergonomic grip. The upper shell 2 and lower shell 3 are respectively installed at both ends of the outer shell 1 to further protect the internal structure. Together with the outer shell 1, they form a closed space to maintain the stability of the air duct structure. The active cooling unit is installed at the lower end of the outer shell 1 and is responsible for generating cool air and guiding it to the palm, thus achieving the function of cooling the palm. The control circuit board 5 is installed at the upper end of the outer shell 1 and is used to control the operating status of the active cooling unit, such as adjusting the fan speed. The battery 8 is also located at the upper end of the outer shell 1, providing power support for the active cooling unit and ensuring the normal operation of the device. The first air outlet 13 and the second air outlet 14 are opened on the outer shell 1 and serve as channels for the exhaust of cool air, guiding the cool air generated by the active cooling unit to the palm. The air inlet 12 is located on the lower shell 3 and serves as the entrance for outside air to enter the device, providing an air source for the active cooling unit.

[0026] like Figures 1 to 6As shown, in a specific embodiment, the active cooling unit includes a fan 6, and a motor 16 is mounted on the back of the fan 6. In this configuration, the fan 6 is an active cooling unit that rotates at high speed under the drive of the motor 16, generating airflow and forming cool air. It is a key component for cooling the palm of the hand. The motor 16 is mounted on the back of the fan 6 to provide power for the rotation of the fan 6 and to control the speed of the fan 6 to adjust the airflow intensity.

[0027] like Figures 1 to 6 As shown, furthermore, four buckles 9 are provided at both ends of the outer shell body 1, and four slots 10 are provided on both the upper shell 2 and the lower shell 3. The buckles 9 and the slots 10 cooperate with each other. In this configuration, the buckles 9 are located at both ends of the outer shell body 1 and cooperate with the slots 10 on the upper shell 2 and the lower shell 3 to fix the upper shell 2 and the lower shell 3, making the entire equipment structure stable, ensuring that all parts of the equipment are tightly connected, and preventing loosening.

[0028] like Figures 1 to 6 As shown, the main body 1 has a mounting cavity 7, in which a battery 8, a lithium polymer battery, is installed. The main body 1 also has a charging interface 15 for charging the battery 8, which is a Type-C interface. In this configuration, the mounting cavity 7, located within the main body 1, is used to install the battery 8, providing positioning and protection. The lithium polymer battery 8 powers the device, ensuring its stable operation over extended periods. The charging interface 15, located on the main body 1 and using a Type-C interface, facilitates connection to an external power source for charging the lithium polymer battery 8.

[0029] like Figures 1 to 6 As shown, a through hole 11 is provided on the upper housing 2, and a switch 4 is installed in the through hole 11. The switch 4 is connected to the control circuit board 5. In this configuration, the through hole 11 is provided on the upper housing 2 to install the switch 4, allowing the switch 4 to contact the outside for easy user operation. The switch 4 is installed in the through hole 11 and connected to the control circuit board 5. The user controls the opening and closing of the equipment and adjusts the operating level by operating the switch 4.

[0030] like Figures 1 to 6 As shown, several first air outlets 13 and several second air outlets 14 all adopt a sunken honeycomb mesh design, and several air inlets 12 are spiral tapering air ducts with guide fins covering the inner wall. In this configuration, the sunken honeycomb mesh design of the first air outlets 13 and second air outlets 14 ensures uniform airflow over the palm-covered area when the device is held, making the cool air more concentrated and evenly blown towards the palm, thus improving the heat dissipation effect. The spiral tapering air ducts and the guide fins covering the inner wall of the air inlets 12 accelerate the intake air and reduce turbulence, ensuring that the air entering the device can be utilized efficiently, thus improving the working efficiency of the active cooling unit.

[0031] Example 2:

[0032] The difference between this embodiment and the previous one is that the active cooling unit includes a thermoelectric cooler and a miniature cooling fan. In this configuration, the thermoelectric cooler and the miniature cooling fan work together to actively cool the device through the Peltier effect, which can replace the pure air cooling mode. The added cooler, in conjunction with the fan, accelerates heat exchange, achieving a lower temperature difference output, making it suitable for scenarios where hand temperature is more sensitive.

[0033] Example 3:

[0034] The difference between this embodiment and the previous one is that the active cooling unit includes a heat pipe and a fan. In this design, similar to the heat pipe and coolant design of a mobile phone radiator, a copper micro-heat pipe is added, filled with a phase-change coolant. The coolant absorbs heat from the palm through circulation, and the fan accelerates evaporation and heat dissipation, thus improving the duration of cooling.

[0035] Example 4:

[0036] The difference between this embodiment and the previous one is that the active cooling unit includes a bladeless fan and a water-cooled sponge. In this configuration, the built-in water-cooled sponge serves as a water storage medium. When in use, the fan is activated after the sponge is wetted, and the cooling effect is enhanced through water evaporation, thus achieving both temperature reduction and humidity regulation.

[0037] The implementation principle of a palm-shaped heat sink in this embodiment is as follows: This palm-shaped heat sink integrates aerodynamics, ergonomics, and electronic circuit control principles. All components work together to achieve efficient palm cooling and sweat removal. After the device is turned on, the motor 16 drives the fan 6 to rotate at high speed, creating a negative pressure at the bottom of the fan 6. External air is drawn in through the air inlet 12 of the spiral-shaped converging air duct in the lower housing 3. The air is then reduced and accelerated by the guide fins, and blown towards the palm through the first air outlet 13 and the second air outlet 14 of the recessed honeycomb grid design in the outer shell 1. Utilizing the principle of evaporative heat absorption, different fan speed settings achieve corresponding functions, with the first setting providing protection against heat loss. The device features three speed settings: static sweating, active cooling at a certain ambient temperature, and rapid sweat evaporation. It adopts a dumbbell-shaped symmetrical design, approximately 110mm in length, with a cylindrical grip area in the middle (35-38mm in diameter). Weighing less than 200g, the weight is balanced at both ends. The grip area in the middle of the main body 1 is made of non-slip silicone. The fan 6, battery 8, and control circuit board 5 are separately and independently packaged, ensuring a comfortable grip while avoiding localized heat generation and airflow interference. The control circuit board 5 integrates multiple functional modules, allowing for three speed settings via a single button on the top. The built-in lithium polymer battery 8, along with the charging port 15, supports Type-C fast charging.
