Description

Technical Field

[0001] The utility model relates to the technical field of cooling fans, in particular to a modular TEC refrigeration mechanism. Background Art

[0002] With the improvement of living standards, people's outdoor travel activities have increased, and desktop and movable cooling fans for cooling are used frequently. The designs of the cooling structures of these cooling fans are also diverse. In current technology, cooling fans mainly rely on the following methods to achieve cooling:

[0003] 1. Simply rely on circulating the water in the bottom water tank to cool it down;

[0004] 2. Add a small ice crystal box to the bottom water tank, and cool it down by circulating a small amount of ice crystals and water;

[0005] 3. Add a small salt water box to the bottom water tank, and cool it down by circulating a small amount of salt water with water;

[0006] 4. Place a water curtain filter at the connection with the water tank, and the wind blown out by the fan directly acts on the filter.

[0007] In the above technical solution, a small amount of ice crystals placed in water cannot achieve a significant cooling effect, and a small amount of salt water placed in water cannot achieve a significant cooling effect either. The cooling duration is limited, and it is inconvenient to carry and store, which has major defects. Utility Model Content

Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0029] The modular TEC refrigeration mechanism of the preferred embodiment of the utility model is as follows Figure 1 As shown, it includes a sealed shell 10. Specifically, the sealed shell 10 is a square shell structure. A first window 20 is provided on the sealed shell 10. A first heat pipe heat conducting component 30, a first fan 40, a TEC refrigeration sheet 50 and an ultrasonic atomization component 60 are provided in the sealed shell 10. Among them, the ultrasonic atomization component 60 is generally an ultrasonic atomizer. The first heat pipe heat conducting component 30 is located between the first fan 40 and the first window 20. The cold end of the TEC refrigeration sheet 50 is connected to the first heat pipe heat conducting component 30. The ultrasonic atomization component 60 is arranged at the bottom of the sealed shell 10 and is located on the side of the first heat pipe heat conducting component 30 away from the first window 20. The water inlet end of the ultrasonic atomization component 60 passes through the bottom of the sealed shell 10 to achieve water-electricity separation; a heat dissipation component 70 for dissipating heat for the hot end of the TEC refrigeration sheet 50 is provided on the outer wall of the sealed shell 10 to reduce the hot end temperature of the TEC refrigeration sheet 50 to ensure that it can perform efficient cooling work;

[0030] The overall structure is simple, and each component is encapsulated by a sealed shell 10 to form a modular design. It has a small size and can be used not only alone, but also in conjunction with an ordinary fan or humidifier. It is easy to carry, has a good cooling effect and can continue to cool for a long time, and has high adaptability and practicality.

[0031] Specifically, when in use, a water box 100 can be set at the lower end of the sealed shell 10, the water inlet end of the ultrasonic atomization component 60 is immersed in water, and the equipment is started. The first heat pipe thermal conductive component 30 is cooled and cooled through the cold end of the TEC refrigeration plate 50, and the ultrasonic atomization component 60 sprays water mist to the first heat pipe thermal conductive component 30. At the same time, the first fan 40 also blows the water mist to the first heat pipe thermal conductive component 30 and sprays it through the first window 20, so that the temperature of the water mist passing through the first heat pipe thermal conductive component 30 is reduced by the low-temperature first heat pipe thermal conductive component 30, so that the user can not only feel the cool feeling of the wind when using it, but also feel the cool feeling brought by the cool water mist. Water can also be replenished while blowing, and the surrounding environment can be humidified, which provides a better user experience.

[0032] In this embodiment, a recess 80 for mounting the heat dissipation assembly 70 is provided on the sealed housing 10, and the recess 80 is opposite to the first window 20 front and back, thereby increasing the compactness of the overall structure, further reducing the overall thickness front and back, and maximizing the distance between the cold-end air outlet of the TEC refrigeration plate 50 and the heat dissipation airflow at the hot end to avoid mutual influence, thereby optimizing the structural layout and making the overall appearance of the mechanism have a symmetrical aesthetic.

[0033] In this embodiment, the heat dissipation assembly 70 includes a second heat pipe heat conduction assembly 71, and a second fan 72 for blowing air to dissipate heat from the second heat pipe heat conduction assembly 71. A second window 81 is provided on the bottom surface of the recess 80 for the TEC refrigeration sheet 50 to pass through, and the hot end of the TEC refrigeration sheet 50 is connected to the second heat pipe heat conduction assembly 71 through the second window 81. The second heat pipe heat conduction assembly 71 includes a rear heat conduction plate 711 that seals the second window 81, and heat dissipation fins 712 provided on the rear heat conduction plate 711. The rear heat conduction plate 711 seals the second window 81 to avoid interference between the hot and cold air in front and behind the sealed housing 10. The heat dissipation fins 712 and the second fan 72 are both located on a side wall of the rear heat conduction plate 711 away from the second window 81. The bottom surfaces of the rear heat conduction plate 711 and the recess 80 are both square in shape and fit each other to increase stability after assembly and facilitate early installation. The second fan 72 continuously blows on the heat dissipation fins 712 to quickly take away the heat from the hot end of the TEC cooling sheet 50, thereby ensuring the cooling effect.

[0034] In this embodiment, a plurality of heat dissipation fins 712 are provided and arranged around the second fan 72. In practice, the heat dissipation fins 712 can be arranged radially with the second fan 72 as a circle to improve the heat dissipation efficiency so that each heat dissipation fin 712 can be sufficiently cooled.

[0035] In this embodiment, the heat dissipation fins 712 and the second fan 72 are both located in the recess 80, and are flush with the rear side wall of the sealed housing 10 after assembly, so as to enhance the overall aesthetics of the mechanism, provide a better feel when the user holds it, and avoid protruding edges that are easily scratched.

[0036] In this embodiment, the first heat pipe heat conduction component 30 includes a front heat conduction plate 31 that is attached to the cold end of the TEC refrigeration plate 50, a heat dissipation grille 32 disposed between the front heat conduction plate 31 and the first window 20, and a heat conduction heat pipe 33 that connects the front heat conduction plate 31 and the heat dissipation grille 32. The heat conduction heat pipe 33 can transfer the low temperature on the cold end of the TEC refrigeration plate to each heat dissipation grille 32 in the fastest way, so that the temperatures of the two are gradually close; the ultrasonic atomization component 60 is located between the heat dissipation grille 32 and the first fan 40, so that the water mist sprayed by it can be sprayed to the heat dissipation grille 32 and fill the entire interior of the sealed housing 10.

[0037] In this embodiment, the outer diameter of the heat dissipation grille 32 is greater than the outer diameter of the first window 20, so that the airflow and water mist flowing out through the edge of the first window 20 can exchange heat with the heat dissipation grille 32 to reduce the temperature.

[0038] In this embodiment, the first fan 40 is a cross-flow fan and is arranged along the length or width direction of the first window 20 to ensure that the wind is blown evenly, so that the water mist can be evenly distributed at various positions of the heat dissipation grille, and the cooling area of ​​the heat dissipation grille is fully utilized. Furthermore, the first fan is located below the recess to fully utilize the internal space, which can further reduce the overall volume.

[0039] In this embodiment, a guide weir 90 surrounding the first window 20 is provided on the sealed housing 10 to increase the speed of the blown air flow.

[0040] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
