Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted hot and cold cup technology, specifically to a heat dissipation air duct structure for a vehicle-mounted hot and cold cup. Background Technology

[0002] A car-mounted hot / cold mug is a smart cup that can be heated and cooled using the vehicle's power supply, allowing people to enjoy beverages at a comfortable temperature while driving long distances. Currently, most car-mounted hot / cold mugs use semiconductor materials as cooling elements. Based on the Peltier effect, when current passes through the semiconductor module, heat is absorbed on one side (cooling) and released on the other side (requiring a cooling fan). However, the existing heat dissipation and ventilation structures of car-mounted hot / cold mugs are complex, resulting in a large size and poor airflow within the cup, leading to ineffective cooling. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a heat dissipation duct structure for a vehicle-mounted hot and cold cup that is simple and compact, small in size, portable, has good air flow effect, and can effectively improve the cooling response speed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A heat dissipation duct structure for a vehicle-mounted hot and cold cup includes an upper housing, a radiator disposed within the upper housing, a lower housing, and a heat dissipation fan disposed within the lower housing. The radiator includes a base and fins. The bottom wall of the upper housing is formed with a cavity for accommodating the base, and a through hole is provided in the cavity for the fins to pass through.

[0006] The lower housing includes a large-diameter section, a platform section, and a small-diameter section. The fins are located in the large-diameter section, and the cooling fan is located in the small-diameter section. Several sets of air inlets are opened on the small-diameter section, and several sets of air outlets are opened on the large-diameter section. A connecting frame is provided on the platform section, and ventilation holes are opened on the connecting frame. The air inlets, the cooling fan, the ventilation holes, the fins, and the air outlets are sequentially connected to form a cooling air duct.

[0007] As a further improvement to the above technical solution:

[0008] The top of the connecting frame is formed with an upper air guide wall surrounding the outer periphery of the lower end of the fins, and the bottom of the connecting frame is formed with a lower air guide wall surrounding the outer periphery of the output end of the cooling fan.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] The heat dissipation duct structure of this vehicle-mounted hot / cold cup includes an upper shell, a radiator, a lower shell, and a cooling fan. The base of the radiator is embedded in the cavity of the upper shell, and the fins of the radiator extend through the upper shell and into the large-diameter section of the lower shell. The cooling fan is located in the small-diameter section of the lower shell. Multiple sets of air inlets are opened on the small-diameter section, and multiple sets of air outlets are opened on the large-diameter section. This makes the space occupied by the radiator base in the upper shell small. At the same time, the fins of the radiator and the cooling fan are both set in the lower shell. The cold air output by the cooling fan blows directly onto the fins, which can effectively increase the air flow speed at the fins and improve the convective heat transfer efficiency, thereby reducing the temperature of the semiconductor cooling chip and improving the cooling speed. It has the advantages of simple and compact structure, small size, good portability, and good air flow effect, and can effectively improve the cooling response speed. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 5As shown, the heat dissipation duct structure of the vehicle-mounted hot and cold cup in this embodiment includes an upper shell 1, a radiator 2 disposed in the upper shell 1, a lower shell 3, and a heat dissipation fan 4 disposed in the lower shell 3. The radiator 2 includes a base 201 and fins 202. The bottom wall of the upper shell 1 is formed with a cavity 101 for accommodating the base 201. A through hole 102 for the fins 202 to pass through is provided in the cavity 101. The lower shell 3 includes a large diameter section 301, a platform section 302, and a small diameter section 303. The fins 202 are located in the large diameter section 301, and the heat dissipation fan 4 is located in the small diameter section 303. Several sets of air inlets 5 are provided on the small diameter section 303, and several sets of air outlets 6 are provided on the large diameter section 301. A connecting frame 7 is provided on the platform section 302, and a ventilation hole 701 is provided on the connecting frame 7. The air inlets 5, the heat dissipation fan 4, the ventilation hole 701, the fins 202, and the air outlets 6 are sequentially connected to form a heat dissipation duct. The heat dissipation duct structure of this vehicle-mounted hot and cold cup includes an upper shell 1, a radiator 2, a lower shell 3, and a cooling fan 4. The base 201 of the radiator 2 is embedded in the cavity 101 of the upper shell 1. The fins 202 of the radiator 2 extend out of the upper shell 1 and into the large-diameter section 301 of the lower shell 3. The cooling fan 4 is located in the small-diameter section 303 of the lower shell 3. Multiple sets of air inlets 5 are opened on the small-diameter section 303, and multiple sets of air outlets 6 are opened on the large-diameter section 301. This makes the base 201 of the radiator 2 occupy less space in the upper shell 1. At the same time, the fins 202 of the radiator 2 and the cooling fan 4 are both set in the lower shell 3. The cold air output by the cooling fan 4 blows directly onto the fins 202, which can effectively increase the air flow speed at the fins 202, improve the convective heat transfer efficiency, thereby reducing the temperature of the semiconductor cooling chip and improving the cooling speed. It has the advantages of simple and compact structure, small size, good portability, and good air flow effect, which can effectively improve the cooling response speed.

[0020] Preferably, the top of the connecting frame 7 is formed with an upper air guide wall 702 surrounding the lower outer periphery of the fin 202, and the bottom of the connecting frame 7 is formed with a lower air guide wall 703 surrounding the outer periphery of the output end of the cooling fan 4. In this embodiment, the cold air blown out from the output end of the cooling fan 4 is guided by the lower air guide wall 703 and will not flow outwards within the small diameter section 303, reducing airflow loss and air velocity reduction. The cold air is blown towards the large diameter section 301 through the ventilation hole 701, and after being guided by the upper air guide wall 702, it will not flow outwards within the large diameter section 301, so that the cold air is concentrated and blown towards the fin 202, which can effectively improve the heat dissipation efficiency of the fin 202, rapidly reduce the temperature of the semiconductor cooling chip, and improve the cooling speed.

[0021] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
