[0025] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0026] Please refer to Figure 1 and Figure 2 , a sealed flow-guiding heat dissipation component of the present utility model includes an outer ring body 1, an inner ring body 2, rib strips 3 and a flow-guiding component 4. The central axes of the outer ring body 1, the inner ring body 2 and the flow-guiding component 4 coincide with each other;

[0027] The inner ring body 2 is located inside the outer ring body 1, and the rib strips 3 connect the inner ring body 2 and the outer ring body 1;

[0028] The rib strips 3 are provided with positioning grooves 31, and the positioning grooves 31 are arranged on the upper surface of the rib strips 3;

[0029] The flow-guiding component 4 is in the shape of an annular body with upper and lower openings. The flow-guiding component 4 includes an upper opening 41 and a lower opening 42, and the upper opening 41 is connected to the inner ring body 2;

[0030] The inner ring body 2 and the flow guide member 4 form a main air duct for air circulation.

[0031] Specifically, in this embodiment, the outer ring body 1 and the inner ring body 2 are arranged on the same central axis. The number of rib strips 3 is multiple. The rib strips 3 are used to connect the outer ring body 1 and the inner ring body 2. The spacing between two adjacent rib strips 3 is set so that a gap is formed between the outer ring body 1 and the inner ring body 2 for air flow. The upper end surfaces of the rib strips 3 are flush with the upper end surface of the outer ring body 1. The rib strips 3 and the outer ring body 1 are used to fix the external LED circuit board 100. The setting of the positioning groove 31 further fixes the external LED circuit board 100 to improve the installation stability. The flow guide member 4 is located directly below the inner ring body 2. The flow guide member 4 is in a horn shape. An external cooling fan 300 is installed below the flow guide member 4 to improve the fluidity of the air flow. The horn-shaped setting of the flow guide member 4 increases the fluidity of the air flow.

[0032] By providing a closed flow guide type heat dissipation member composed of the outer ring body 1, the inner ring body 2, the rib strips 3 and the flow guide member 4, the channels for air flow are increased, the effect of guiding the flow is achieved, and the purpose of rapid cooling is achieved.

[0033] The number of the rib strips 3 is multiple. The multiple rib strips 3 are arranged in a ring array around the central axis of the outer ring body 1, which improves the stability of the connection structure between the outer ring body 1 and the inner ring body 2. At the same time, the supporting force for the external LED circuit board 100 is increased, and the assembly firmness is improved.

[0034] The upper end surface of the inner ring body 2 is lower than the upper end surface of the outer ring body 1. The external LED circuit board 100 is arranged with a gap from the inner ring body 2, which increases the flowable space of the air flow and improves the fluidity of the air flow.

[0035] The closed flow guide type heat dissipation member further includes a convex column 5. The convex column 5 is arranged on the inner surface of the inner ring body 2. The setting of the convex column 5 increases the heat dissipation area of the inner ring body 2 and improves the heat dissipation efficiency.

[0036] The caliber of the upper opening 41 is smaller than the caliber of the lower opening 42, which increases the flowable space of the air flow and accelerates the air flow.

[0037] The flow guide member 4 and the inner ring body 2 are integrally formed. The outer ring body 1 and the rib strips 3 are integrally formed. The rib strips 3 are inserted into the inner ring body 2.

[0038] The working principle of the closed flow guide type heat dissipation member is as follows: As Figure 3As shown in the figure, an external transparent cover 200 and an external base 400 are connected to form a receiving cavity. The transparent cover 200 is provided with a first air duct 201, and the base 400 is provided with a number of second air ducts 401. The first air duct 201 is communicated with the receiving cavity, and the second air duct 401 is communicated with the receiving cavity. The external LED circuit board 200 is installed on the upper surface of the airtight flow guiding heat sink. The flow guiding member 4 is connected to the external heat dissipation fan 300. That is, the external LED circuit board 200, the airtight flow guiding heat sink and the heat dissipation fan 300 are installed in the receiving cavity. During the working process, the external cold air flows through the first air duct 201 of the transparent cover 200 and enters the receiving cavity. The heat dissipation fan 300 drives the air to flow rapidly. The cold air carries the hot air generated by the LED circuit board 100 and flows downward through the inner ring body 2 into the flow guiding member 4 and flows out through the second air duct 401, so as to achieve the flow of the air and the purpose of rapid heat dissipation.

[0039] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present invention.
