Description

Technical Field

[0001] This utility model relates to the field of cooling devices, and in particular to a portable cooling device. Background Technology

[0002] Currently, with the advancement of technology and the improvement of people's living standards, many people enjoy traveling, picnicking, and other outdoor sports. At the same time, high-temperature working environments are prevalent in many industries and fields, such as fire fighting, metallurgy, tunnels, and coal mines, requiring more and more workers to engage in high-temperature operations. Furthermore, with the greenhouse effect intensifying, temperatures are getting hotter year by year, especially in summer when outdoor temperatures can reach as high as 40 degrees Celsius. Due to the limited regulatory functions of the human body, prolonged walking or working in high-temperature environments can not only affect the user's physical health but also lead to a decline in the user's comprehension and other intelligent operational abilities due to excessively high body surface temperature, resulting in problems such as heatstroke and dehydration, which can even be life-threatening in severe cases.

[0003] Existing technologies for outdoor cooling primarily involve standing fans, handheld fans, and neck fans. However, the airflow from these fans is easily affected by the outdoor temperature, resulting in hot air being blown out and poor cooling performance. Furthermore, although some fan products have a cavity for storing liquid, allowing the fan to carry liquid with it when blowing out the air to improve the cooling effect, these fans require frequent refilling of the liquid after prolonged use, which is cumbersome and inconvenient.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

It utilizes the first and second heat pipe groups to connect the cold end and hot end of the TEC cooler to the copper plate and the cooling fan respectively, thereby improving the cooling effect of the copper plate and the heat dissipation and temperature control effect of the hot end of the TEC cooler. This is beneficial for users to use outdoors or in high-temperature environments, ensuring the stability of the product, providing excellent cooling effect, and having a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The inner end of the copper plate 11 is restricted by the positioning step 102. The outer wall of the connecting edge 111 is connected and fixed to the inner wall of the chamber 101.

[0041] The TEC cooler 14 has a cold end and a hot end. The cold end of the TEC cooler 14 is located on one side of the copper plate 11, and the cooling fan 15 is located on the hot end side of the TEC cooler 14. The first heat pipe assembly 12 is located between the copper plate 11 and the cold end, and the second heat pipe assembly 13 is located between the hot end and the cooling fan 15.

[0042] It also includes a conductive mechanism 18, which is disposed on the chamber 101 and located next to the cooling fan 15.

In this way, through the design of each component, the cold end and hot end of the TEC cooler are connected to the copper plate and the cooling fan respectively by the first and second heat pipe groups, which improves the cooling effect of the copper plate and the heat dissipation and temperature control effect of the hot end of the TEC cooler. This is beneficial for users to use outdoors or in high-temperature environments, ensures the stability of the product, has a clever and reasonable structural design, is easy to use, has a good cooling effect, and is widely applicable.

[0043] In this embodiment, a partition 16 extending towards the opening is provided on the chamber 101. Four partitions 16 are arranged sequentially around the inner wall of the chamber 101, forming a mounting groove 161. The first heat pipe assembly 12, the second heat pipe assembly 13, the TEC cooler 14, and the cooling fan 15 are all mounted on the mounting groove 161. The outer end of the partition 16 contacts and is positioned with the inner end of the copper plate 11. The positioning step 102 is formed on the outer end of the partition 16. Specifically, a reinforcing edge 162 is provided between the outer wall of the partition 16 and the inner wall of the chamber 101. Several reinforcing edges 162 are provided and arranged at intervals along the length of the partition 16. In this way, the setting of the reinforcing edge improves the structural strength of the partition in the chamber, which helps to reduce the impact of the shell on the components inside the chamber when it is hit, thereby ensuring the stability and usability of the components in the chamber.

[0044] Furthermore, the chamber 101 has a positioning post 104 extending toward the cooling fan, and the cooling fan 15 is provided with a positioning groove 151 that matches and positions the positioning post. Both the positioning post 104 and the positioning groove 151 are provided with connecting holes.

[0046] Preferably, a heat sink 172 is provided on the end face of the heat sink 171 away from the second heat pipe assembly 13. Multiple heat dissipation protrusions 173 are provided on both sides of the heat sink 172, and heat dissipation channels 174 are formed between adjacent heat dissipation protrusions 173. Several second heat dissipation holes 105 are provided and are arranged corresponding to the heat dissipation channels 174. The heat dissipation protrusions 173 are spaced from the inner end face of the chamber 101. In this way, the arrangement of the heat sink effectively increases the heat dissipation surface area, increases the speed at which heat is dissipated towards the air, and further improves the heat dissipation efficiency.

[0047] The key design feature of this utility model is that, through the design of each component, the cold end and hot end of the TEC cooler are connected to the copper plate and the cooling fan respectively by the first and second heat pipe groups. This improves the cooling effect of the copper plate and the heat dissipation and temperature control effect of the hot end of the TEC cooler, which is beneficial for users to use outdoors or in high-temperature environments. It ensures the stability of the product, has a clever and reasonable structural design, is easy to use, has a good cooling effect, and is widely applicable.

[0048] Secondly, the design of connecting edges and positioning steps facilitates the assembly and positioning of the copper plate on the housing, simplifying operation and assembly and improving production efficiency. At the same time, the reinforced edges enhance the structural strength of the partition in the chamber, reducing the impact of collisions on the internal components of the chamber and ensuring the stability and usability of each component in the chamber.

[0049] Furthermore, the placement of positioning posts and slots facilitates the assembly and positioning of the cooling fan within the chamber. The combination of three positioning posts and three positioning slots ensures foolproof assembly of the cooling fan within the chamber, guaranteeing accurate positioning and ensuring the effective heat dissipation of the second heat pipe assembly. Simultaneously, the heat dissipation structure utilizes the contact between the heat sink and the second heat pipe assembly to enhance its heat dissipation, facilitating rapid cooling of the hot end of the TEC cooler. Additionally, the placement of heat sinks effectively increases the heat dissipation surface area, accelerating heat dissipation towards the air and further improving heat dissipation efficiency.
