Boosters provide additional thrust or torque to devices that previously required human power or other power sources, increasing their efficiency or expanding their operating range. Boosters continuously generate heat during use, making their heat dissipation structure crucial. Current booster cooling methods rely on grilles, which have poor heat dissipation efficiency, and some hot air bypasses the grilles, resulting in low overall cooling efficiency.

[0013] Another technical solution of this utility model is implemented as follows:

[0014] An auxiliary device includes an auxiliary device body and a heat dissipation structure, wherein the auxiliary device body and the heat dissipation structure are connected in cooperation.

[0015] Compared with the prior art, this utility model sets the grille assembly and the fan cover on the heat dissipation housing, so that the fan cover and the heat dissipation housing form a heat dissipation channel.

[0024] Example 1

[0025] Embodiment 1 of this utility model provides a heat dissipation structure for an amplifier, see [link to embodiment 1]. Figures 1 to 4 It includes a heat dissipation housing 1, a grid assembly 2 and a fan shroud 3 disposed on the heat dissipation housing 1, and the fan shroud 3 and the heat dissipation housing 1 together form a heat dissipation channel 4; when in use, the heat generated by the booster passes through the heat dissipation channel 4 and the grid assembly 2 in sequence, thereby achieving heat dissipation of the booster.

[0026] By adopting the above solution, the present invention sets the grille assembly 2 and the fan cover 3 on the heat dissipation housing 1, so that the fan cover 3 and the heat dissipation housing 1 form a heat dissipation channel 4. The gas can pass through the heat dissipation channel 4 and the grille assembly 2 in sequence, thereby achieving heat dissipation of the booster. The present invention uses the heat dissipation channel 4 for the first heat dissipation and the grille assembly 2 for the second heat dissipation, so that the present invention has high heat dissipation efficiency and good heat dissipation effect. The present invention has a simple structure and low cost, and is worth promoting and using.

[0027] See Figures 1 to 4 In a specific implementation of Embodiment 1 of this utility model, the grille assembly 2 further includes a plurality of grille bodies 21, and the gap formed between two adjacent grille bodies 21 is connected to the heat dissipation channel 4. The gap formed between two adjacent grille bodies 21 increases the heat dissipation area and enhances the heat dissipation effect; at the same time, the grille body 21 can accelerate the flow rate of hot air and enhance the heat dissipation efficiency.

[0028] See Figure 2 In a specific implementation of Embodiment 1 of this utility model, a first guiding surface 211 for guiding heat in the heat dissipation channel 4 is further provided on one end of the grille body 21 near the shroud 3. The first guiding surface 211 is set at an inclined angle, which conforms to fluid mechanics, increases the contact area of ​​hot air, and plays a guiding role.

[0029] See Figure 2 In a specific implementation of Embodiment 1 of this utility model, a second guiding surface 212 is further provided at one end of the grille body 21 away from the heat dissipation channel 4 for guiding the heat between two adjacent grille bodies 21. The second guiding surface 212 is set at an inclined angle; when the hot air between two adjacent grille bodies 21 flows to the second guiding surface 212, the second guiding surface 212 guides the hot air into the air, thus enhancing the heat dissipation effect.

[0030] See Figure 4 In a specific implementation of Embodiment 1 of this utility model, a groove 11 is further provided on the heat dissipation housing 1, and the fan cover 3 is disposed on the groove 11. The groove 11 is a mounting groove for the fan cover 3, so that the fan cover 3 can be stably disposed on the heat dissipation housing 1.

[0031] See Figure 1 and Figure 4 In a specific implementation of Embodiment 1 of this utility model, the fan cover 3 is further provided with a diversion component 31 for diverting the heat in the heat dissipation channel 4.

[0032] In this embodiment of the utility model, the flow divider 31 is set to one, but in reality, it can be set to several; the more flow dividers 31 there are, the faster the gas flow rate in the heat dissipation channel 4, and the better the cooling effect.

[0033] See Figure 1 , Figure 3 as well as Figure 4 In a specific implementation of Embodiment 1 of this utility model, the heat dissipation housing 1 further includes a first housing 12 and a second housing 13, with the first housing 12 connected to the second housing 13. The grille body 21 and the fan shroud 3 are both disposed on the first housing 12. The first housing 12 is used to support the heat dissipation channel 4 and the grille assembly 2, and the second housing 13 is used to connect the booster.

[0034] The working principle of the heat dissipation structure provided in Embodiment 1 of this utility model is as follows:

[0035] See Figures 1 to 4First, the heat generated by the booster is transferred to the end of the first housing 12 through the second housing 13 and flows into the heat dissipation channel 4. After passing through the heat dissipation channel 4, the flow rate increases. Then, some of the hot air flows into the air through the first guide surface 211. The remaining hot air passes between two adjacent grille bodies 21. Finally, the remaining hot air flows into the air from the second guide surface 212, completing the heat dissipation process.

[0036] Example 2

[0037] An auxiliary device is provided in Embodiment 2 of this utility model, see [link]. Figure 5 It includes a heat dissipation structure as described in Embodiment 1 and an booster body 5, wherein the booster body 5 is connected to the heat dissipation structure.

[0038] See Figure 5 In a specific implementation of Embodiment 2 of this utility model, the booster body 5 further includes a lifting structure 51 and a booster wheel 52, both of which are connected to the second housing 13. The lifting structure 51 lifts the booster wheel 52 through the second housing 13; the booster wheel 52 is used to assist the bicycle tires; and the heat dissipation structure is used to dissipate heat from the lifting structure 51.

[0039] By applying the heat dissipation structure in Example 1 to the existing booster body 5, the problem of poor heat dissipation effect of the heat dissipation structure in the prior art can be solved.

[0040] In summary, this utility model places the grille body 21 and the fan shroud 3 on the heat dissipation housing 1, so that the fan shroud 3 and the heat dissipation housing 1 form a heat dissipation channel 4, allowing gas to pass through the heat dissipation channel 4 and the grille assembly 2 in sequence, thereby achieving heat dissipation for the booster. This utility model utilizes the heat dissipation channel 4 for the first heat dissipation, and at the same time utilizes the gap between two adjacent grille bodies 21 for the second heat dissipation, making the heat dissipation efficiency high and the heat dissipation effect good. This utility model has a simple structure and low cost, and is worth promoting and using.
