Referring to fig. 1 and 2, an efficient and energy-saving heat dissipation fan comprises a fan body 1 and a flow guiding member 2, wherein the fan body 1 is detachably and fixedly connected to the top surface of a heat dissipation module 3. The heat source of some existing electrical or electronic devices is provided with a heat dissipation module 3, and the fan main body 1 can be fixedly connected with the heat dissipation modules 3. Such a heat dissipating module 3 generally includes a base and a plurality of heat dissipating fins 31 disposed on the base. The air flow is blown to the top of the heat dissipation module 3, enters the inside from the gaps between the heat dissipation fins 31 at the two sides and flows out laterally from the positions of the two sides close to the lower side, and the two sides are the air outlet sides.
The guide piece 2 of the above embodiment is detachably and fixedly connected to the fan main body 1, a guide channel is arranged in the guide piece 2, an air inlet and an air outlet which are communicated with the guide channel are respectively arranged at the upper end and the lower end of the guide piece 2, an inclined first guide plate 21 is further arranged at the air outlet of the guide piece 2, the first guide plate 21 is positioned at the air outlet side of the heat radiation module 3, so that the airflow transversely blown out from the air outlet side of the heat radiation module 3 is changed into oblique downward, and an inclined second guide plate 22 is further arranged in the guide channel, so that the airflow flowing through the guide channel is blown to the upper end of the air outlet side of the heat radiation module 3.
When the fan body 1 of the above embodiment works, air flow is generated to blow the heat dissipation module 3, so that heat of the heat dissipation module 3 is taken away and is transversely blown out from the air outlet side, which is main heat dissipation. The direction of the hot air flowing through the first guide plate 21 is changed into an inclined downward direction, the fast flowing hot air flow generates low pressure to drive the cold air flow above to flow into the guide channel from the air inlet, and the cold air flow is blown to the upper end of the air outlet side of the heat radiation module 3 through the second guide plate 22, so that the heat radiation module 3 is assisted in heat radiation. The heat dissipation effect of the heat dissipation fan is improved as a whole. The hot air flow is reused to generate new cold air flow for heat dissipation, so that the reused air flow can realize the same heat dissipation effect with lower energy consumption, and the energy utilization rate is high and the energy is saved.
In an embodiment, referring to fig. 1 and 2, the air guide member 2 is provided with a cover plate 23 inclined to the fan main body 1 at an air inlet, the air inlet includes a plurality of air inlet holes 24, and the air inlet holes 24 are uniformly arranged on the cover plate 23. In addition, the cover plate 23 is provided with diversion trenches 25 facing the fan main body 1 at positions between the adjacent air inlet holes 24. Thus, part of the air flow flowing to the air inlet enters the diversion channel from the air inlet 24, the rest flows to the fan main body 1, the air quantity of the fan main body 1 is improved, and the diversion trench 25 arranged on the air flow can concentrate the air flow relatively better, so that the air flow flows to the fan main body 1. The baffles 281 extending toward the fan body 1 are arranged on the flow guiding members 2 positioned on two sides of the cover plate 23, so that air flow can be better concentrated at the cover plate 23 for use.
In an embodiment, referring to fig. 1 and 2, the flow guiding channel of the flow guiding member 2 is surrounded by an inner side plate 26, an outer side plate 27 and two side plates 28, the inner side plate 26 is close to the fan main body 1, the outer side plate 27 is far away from the fan main body 1 and is spaced from the inner side plate 26, the two side plates 28 are respectively and fixedly connected to two sides of the inner side plate 26 and the outer side plate 27, and the bottom surface of the inner side plate 26 is flush with the bottom surface of the fan main body 1. The fan main body 1 adopts the prior art, and comprises a shell 11 with an air duct 111 and a fan assembly 12 positioned in the air duct 111, wherein a part between an upper plate and a lower plate of the shell 11 outside the air duct 111 is of a hollowed-out structure, so that the bottom surface of the inner side plate 26 and the bottom surface of the fan main body 1 are arranged to be flush, and air flow is prevented from flowing away from between the upper plate and the lower plate, and the heat dissipation efficiency is reduced.
In the above embodiment, the second baffle 22 is transversely disposed on the inner side surface of the outer side plate 27, and a space is left between the end of the second baffle 22 and the inner side plate 26, so that the air flow flows out, and the connection between the second baffle 22 and the outer side plate 27 is higher, so that the air flow can blow down obliquely to the upper portion of the heat dissipation module 3. Because the fan main body 1 blows directly to the top of the heat dissipation module 3, the air flow can flow to the lower part of the rapid heat dissipation module 3, and thus the air flow does not flow out from the upper part of the air outlet side, and basically flows out from the lower part of the air outlet side, because the influence of the high-speed air flow at the upper part in the heat dissipation module 3, the low pressure for sucking the air flow in the diversion channel to flow to the upper part of the air outlet side can be generated, and the effect of the second diversion plate 22 can basically enable the air flow in the diversion channel to flow to all the upper parts of the air outlet side. The end of the second deflector 22 is preferably disposed close to the air outlet side of the heat dissipation module 3, so that the air flow can flow to the heat dissipation module 3 better, and the low pressure of the air flow at the upper part of the heat dissipation module 3 can be utilized to increase the air flow flowing into the channel better.
In an embodiment, through holes for screws to pass through are formed on two sides of the top surface of the fan body 1 and are in threaded connection with the heat dissipation module 3, and a strip-shaped hole 29 corresponding to the through hole on one side of the guide member 2 is formed on the guide member 2. The strip-shaped hole 29 is convenient for installing the diversion piece 2, when the heat radiation module 3 is larger than the fan main body 1, the diversion piece 2 can be moved outwards, and then the heat radiation module 3 is locked by threaded connection of the strip-shaped hole 29 and the through hole through screws.
The above-described embodiments are merely illustrative of the present invention and are not intended to be limiting, and modifications may be made to the embodiments by those skilled in the art without creative contribution as required after reading the present specification, but are protected by patent laws within the scope of the appended claims.
