Description

Technical Field

[0001] This utility model relates to the field of diodes, and more particularly to anti-reverse diodes used in new energy equipment. Background Technology

[0002] A reverse protection diode is a semiconductor device with unidirectional conductivity. It is mainly used to prevent the current in the circuit from flowing in the opposite direction, thereby protecting other components in the equipment from damage caused by reverse current. Reverse protection diodes are widely used in various new energy equipment.

[0003] Existing reverse-biased diodes utilize the characteristics of a PN junction to achieve unidirectional conduction. When a forward voltage is applied, the P-region is positive and the N-region is negative. The external electric field weakens the built-in electric field of the PN junction, and the carriers diffuse to form a forward current, causing the diode to conduct. When a reverse voltage is applied, the N-region is positive and the P-region is negative. The external electric field strengthens the built-in electric field, and the carriers are pulled away from the PN junction. The PN junction widens and becomes a high-resistance state, preventing current from passing through. The diode is cut off, preventing the current from flowing in the reverse direction and protecting the circuit components. However, existing reverse-biased diodes are often soldered onto related components, making the installation and removal of the diode time-consuming and cumbersome. Utility Model Content

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides an anti-reverse diode for new energy equipment, comprising a diode body 1, a heat sink 2 fixedly connected to the lower surface of the diode body 1, a fixing block 3 fixedly connected to the upper surface of the heat sink 2, a rotating shaft 5 fixedly connected to the inner wall of the fixing block 3, a rotating block 8 rotatably connected to the outer wall of the rotating shaft 5, a reset spring 7 provided on the inner wall of the heat sink 2, a pressure block 10 provided on the upper surface of the rotating block 8, a sliding component provided on the outer wall of the pressure block 10, the sliding component being used to limit the movement trajectory of the pressure block 10, a limit component provided on the inner wall of the heat sink 2, the limit component being used to limit the position of the diode body 1, the limit component being connected to the fixing block 3, the limit component being connected to the rotating block 8, and the limit component being connected to the diode body 1;

[0026] Specifically, pressing the pressure block 10 causes the sliding component to move synchronously. The sliding component is used to limit the movement of the pressure block 10 and prevent it from deviating. Then, the rotating block 8 rotates around the rotating shaft 5 under the action of the pressure block 10. The rotating block 8 disengages from the inside of the limiting component. At the same time, the second reset spring 7 undergoes elastic deformation under the action of the rotating block 8. The second reset spring 7 is used to assist the pressure block 10 in resetting. Then, the limiting component disengages from the inside of the diode body 1. The fixing block 3 can be separated from the diode body 1. Since the heat sink 2 is fixedly connected to the fixing block 3, the diode body 1 can be separated from the heat sink 2. Finally, the purpose of quick installation and removal of the heat sink 2 is achieved, which can facilitate the user to replace and maintain the diode body 1.

[0027] Reference Figure 3 The sliding component includes a slider 11, the outer wall of which is fixedly connected to the outer wall of the pressure block 10. A groove 12 is provided inside the fixed block 3, and the outer wall of the slider 11 is slidably connected to the inner wall of the fixed block 3 through the groove 12.

[0028] Specifically, since the slider 11 is fixedly connected to the pressure block 10, the slider 11 slides inside the fixed block 3 through the slide groove 12 under the drive of the pressure block 10.

[0029] Reference Figure 3 The limiting component includes a reset spring 6, the bottom end of which is disposed on the inner wall of the heat sink 2, and a locking block 9 is disposed on the top end of the reset spring 6. The outer wall of the locking block 9 is disposed on the inner wall of the diode body 1, and the outer wall of the rotating block 8 is disposed on the inner wall of the locking block 9.

[0030] Specifically, when the rotating block 8 disengages from the inside of the locking block 9, the reset spring 6 pushes the locking block 9 back, and at the same time moves the locking block 9 to remove it from the diode body 1.

[0031] Reference Figure 3 The outer wall of the reset spring 7 is set on the inner wall of the rotating block 8, and the outer wall of the pressure block 10 is slidably connected to the inner wall of the fixed block 3.

[0032] Specifically, the reset spring 7 is used to assist the rotating block 8 in resetting, while the fixed block 3 is used to provide a fulcrum for the sliding of the pressure block 10.

[0033] Reference Figure 4 and Figure 5A second heat sink 13 is fixedly connected to the lower surface of heat sink 2. The second heat sink 13 includes a second coating 14, a first thermally conductive layer 15, a second thermally conductive layer 16, and a first coating 4. The outer wall of the second coating 14 is fixedly connected to the outer wall of the first thermally conductive layer 15, the outer wall of the first thermally conductive layer 15 is fixedly connected to the outer wall of the second thermally conductive layer 16, and the outer wall of the second thermally conductive layer 16 is fixedly connected to the outer wall of the first coating 4. The second coating 14 is made of polyimide, the first coating 4 is made of polyimide, the first thermally conductive layer 15 is made of aluminum, and the second thermally conductive layer 16 is made of boron nitride.

[0034] Specifically, heat sink 13 is constructed by combining multiple layers of materials. The outermost layer of heat sink 13 consists of coating 14 and coating 4, both of which are made of polyimide. Polyimide is a high-performance synthetic polymer with good thermal conductivity and mechanical properties, giving heat sink 13 excellent heat dissipation capabilities. A thermally conductive layer 15 is installed inside coating 14. This layer is made of aluminum, which has good thermal conductivity, improving the heat dissipation capacity of the diode surface and also providing corrosion and oxidation resistance. A thermally conductive layer 16 is made of boron nitride, an inorganic compound composed of nitrogen and boron atoms. Boron nitride possesses electrical insulation, good thermal conductivity, high temperature resistance, and wear resistance, making heat sink 13 less prone to wear and extending its lifespan. This further enhances the heat dissipation performance of heat sink 13, thus assisting in the heat dissipation of the diode body 1, preventing damage due to temperature increases after prolonged operation, and improving the lifespan of the diode body 1.

[0035] Working principle: Pressing the pressure block 10 causes the slider 11 to slide, and then the rotating block 8 rotates under the action of the pressure block 10. The rotating block 8 disengages from the inside of the locking block 9. At the same time, the second reset spring 7 undergoes elastic deformation under the action of the rotating block 8. The second reset spring 7 is used to assist the pressure block 10 in resetting, and then the rotating block 8 disengages from the inside of the locking block 9. The first reset spring 6 pushes the locking block 9 back, and at the same time, it moves the locking block 9 to remove the locking block 9 from the diode body 1. The fixing block 3 can be separated from the diode body 1, and then the diode body 1 can be separated from the heat sink 2. This achieves the effect of quickly disassembling and assembling the diode body 1, and makes it convenient for users to replace and maintain the diode body 1 with damaged or dusty surfaces.

[0036] The heat sink 13 is constructed by combining multiple layers of materials. The outermost layer of the heat sink 13 consists of a second coating 14 and a first coating 4. Both the first coating 4 and the second coating 14 are made of polyimide, which gives the heat sink 13 good heat dissipation capabilities. A thermally conductive layer 15 is installed on the inner side of the second coating 14. The thermally conductive layer 15 is made of aluminum, which can improve the heat dissipation capabilities of the heat sink 13. The thermally conductive layer 16 is made of boron nitride, which makes the heat sink 13 less prone to wear and tear, extends its lifespan, and further enhances its heat dissipation performance. This can effectively disperse the heat generated by the diode body 1 during operation, prevent the diode body 1 from being damaged due to increased temperature after long-term operation, and improve the service life of the diode body 1.
