Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a cooling fan. Background Technology

[0002] In the prior art, a cooling fan includes a fan body, on which a cooling fin and a cooling fan are disposed. The cooling fin is located at the air outlet of the cooling fan. When airflow passes through the cooling fin, it can reduce the temperature of the airflow, thereby achieving the effect of cold air. When the cooling fin is in use, it needs to conduct heat through a heat-conducting plate, and the heat on the heat-conducting plate is carried away by a cooling fan. However, when the cooling fan carries away the heat on the heat-conducting plate, it generates hot airflow. When the hot airflow is discharged, it is easy to mix with the cold airflow, thereby affecting its cooling effect. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a cooling fan that uses two independently set gas channels to separate the hot airflow and the cold airflow, thereby avoiding the mixing of hot and cold airflows and making it more effective during use.

[0004] This utility model discloses a cooling fan, comprising a fan body, on which a cooling fan, a cooling fan, a cooling plate, and a heat-conducting plate are disposed. The fan body is characterized by: a guide seat within the fan body, on which independently disposed cold air channels and cooling channels are provided; the cooling fan is disposed on the cold air channels, and the cooling plate is disposed at the outlet end of the cold air channels; the fan body also has a cold air outlet, the outlet end of the cold air channels being connected to the cold air outlet; the heat-conducting plate is disposed on one side of the cooling plate and located within the cooling channels; the cooling fan is disposed at the cooling channels, and the outlet end of the cooling fan faces the heat-conducting plate; and the fan body also has heat dissipation holes for hot air from the cooling channels to be blown out.

[0005] A further feature of this invention is that the outlet end of the cold air flow channel is located at the top of the guide seat, and the outlet end of the heat dissipation flow channel is located at the bottom of the guide seat.

[0006] A further feature of this invention is that the cooling fan is a worm gear fan, and the left and right sides of the fan body are provided with first air inlets that cooperate with the cooling fan. The cold air outlet is provided on the front side of the fan body. The fan body is also provided with a second air inlet for the cooling fan to enter. The second air inlet is located on the front side of the fan body and below the cold air outlet.

[0007] A further feature of this invention is that the fan body is also provided with a battery, a circuit board, and a control switch for driving the cooling fan and the heat dissipation fan. The battery, the cooling fan, the heat dissipation fan, and the control switch are all electrically connected to the circuit board.

[0008] A further feature of this invention is that the upper end of the fan body is hollowed out to form a handle, and the cold air outlet is located on the front side of the handle.

[0009] The specific beneficial effects of this utility model are as follows: When in use, the cooling fan drives the airflow in the cold air channel, and the air temperature drops as it passes through the cooling plate, and is blown out from the cold air outlet, achieving the effect of a cooling fan. At the same time, the heat generated by the cooling plate is conducted to the heat dissipation channel through the heat conduction plate. At this time, the heat dissipation fan works, thereby driving the airflow in the heat dissipation channel and carrying away the heat on the heat conduction plate, and blowing it out from the heat dissipation hole. The use of two independently set gas channels to separate the hot airflow and the cold airflow can avoid the mixing of the hot and cold airflows, making it more effective when in use.

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] This utility model discloses a cooling fan, including a fan body 1. The fan body 1 is provided with a cooling fan 2, a cooling fan 3, a cooling plate 4, and a heat-conducting plate 5. In an embodiment of this utility model, a guide seat 6 is provided inside the fan body 1. The guide seat 6 is provided with an independently provided cold air flow channel 61 and a heat dissipation flow channel 62. The cooling fan 2 is provided on the cold air flow channel 61, and the cooling plate 4 is provided at the outlet end of the cold air flow channel 61. The fan body 1 is also provided with a cold air outlet 7. The outlet end of the cold air flow channel 61 is connected to the cold air outlet 7 (preferably through the inner cavity of the fan body 1). The heat-conducting plate 5 is provided on one side of the cooling plate 4 and is located in the heat dissipation flow channel 62. The cooling fan 3 is provided at the heat dissipation flow channel 62, and the air outlet end of the cooling fan 3 is set towards the heat-conducting plate 5, so that it can blow air directly onto the heat-conducting plate 5 for heat dissipation. The fan body 1 is also provided with heat dissipation holes 8 for hot air to be blown out of the heat dissipation flow channel 62.

[0019] Using the above technical solution, when in use, the cooling fan 2 drives the airflow in the cold air channel 61, and the air temperature drops after passing through the cooling plate 4, and is blown out from the cold air outlet 7, achieving the effect of a cooling fan. At the same time, the heat generated by the cooling plate 4 is conducted to the heat dissipation channel 62 through the heat conduction plate 5. At this time, the cooling fan 3 works, thereby driving the airflow in the heat dissipation channel 62 and carrying away the heat on the heat conduction plate 5, and blowing it out from the heat dissipation hole 8. By using two independently set air channels to separate the hot airflow and the cold airflow, the mixing of the hot and cold airflow can be avoided, making it more effective when in use.

[0020] The outlet end of the cold air flow channel 61 is located at the top of the guide seat 6, and the outlet end of the heat dissipation flow channel 62 is located at the bottom of the guide seat 6, which further prevents the hot air of the heat dissipation flow channel 62 from mixing with the cold air of the cold air flow channel 61, resulting in a better cooling effect during use.

[0021] The cooling fan 2 has a worm gear blade. The fan body 1 has a first air inlet 9 on the left and right sides that cooperates with the cooling fan 2. The cold air outlet 7 is located on the front side of the fan body 1. The fan body 1 also has a second air inlet 10 for the cooling fan 3 to enter. The second air inlet 10 is located on the front side of the fan body 1 and below the cold air outlet 7. With this layout, the cooling fan 3 can draw in some cold air when it enters the fan, thereby increasing its heat dissipation effect. In addition, the use of worm gear blades can facilitate the intake of air from both sides and blow it out from the top, which can avoid directly drawing in the hot air from the heat dissipation holes 8, thereby increasing the cooling effect. The structural layout is relatively reasonable.

[0022] The fan body 1 is also equipped with a battery 20, a circuit board 30, and a control switch 40 for driving the cooling fan 2 and the heat dissipation fan 3. The battery 20, the cooling fan 2, the heat dissipation fan 3, and the control switch 40 are all electrically connected to the circuit board 30. The battery 20 is preferably a rechargeable battery. Using the battery 20 for power supply makes it easier to carry and use, and it is more convenient to use. Furthermore, the control switch 40 makes it easy to start and stop.

[0023] The upper end of the fan body 1 is hollowed out to form a handle 50, and the cold air outlet 7 is located on the front side of the handle 50, which makes the product easy to carry and allows the accessories to be placed at the bottom to prevent it from tipping over, making it more stable during use.
