Description

Technical Field

[0001] The utility model relates to the technical field of data transmission radios, and particularly to a heat dissipation device for an unmanned aerial vehicle (UAV) data transmission radio. Background Art

[0002] A data transmission radio, also known as a wireless data transmission radio or a wireless data transmission module, is a high-performance professional data transmission device realized by using digital signal processing (DSP) technology and radio technology. It is mainly used for wireless data transmission and can realize point-to-point or point-to-multipoint data communication within a certain distance.

[0003] During the use of the existing UAV data transmission radios, when they work at high frequency for a long time, a large amount of heat will be generated inside. Generally, the UAV data transmission radios are of a sealed type. However, to prevent dust from entering and affecting the normal operation of the internal components, ventilation holes are not provided on their shells, so that the heat dissipation method only relies on the heat dissipation fins on the shells for heat dissipation. This heat dissipation method has a poor heat dissipation effect. A poor heat dissipation effect will cause the machine components to short-circuit and unable to operate normally, affecting the use. Summary of the Utility Model

[0004] To solve the technical problems existing in the above background art, the utility model provides a heat dissipation device for a UAV data transmission radio.

[0005] The technical solution of the utility model is as follows:

[0006] A heat dissipation device for a UAV data transmission radio is arranged inside the shell of the UAV data transmission radio. A central processor of the UAV data transmission radio is arranged inside the shell, heat dissipation fins are arranged outside the shell, a heat pipe is arranged inside the shell, and the heat pipe includes a condensation section and an evaporation section. The evaporation section is arranged on the heat dissipation surface of the central processor through a heat dissipation copper seat. A fixing frame is arranged above the heat pipe, the middle of the fixing frame is clamped with the heat pipe, and both ends of the fixing frame are detachably connected to the bottom plate of the shell;

[0007] The condensation section extends inside the shell towards the side close to the heat dissipation fins and is connected to the inner side surface of the shell close to the heat dissipation fins. The lower surface of the condensation section is detachably connected to the bottom plate through a heat dissipation support plate.

[0008] By arranging a heat pipe inside the shell of the UAV data transmission radio, the evaporation section of the heat pipe is in contact connection with the heat dissipation surface, and the condensation section of the heat pipe is in contact connection with the heat dissipation fins of the shell. Utilizing the characteristics of the heat pipe, the heat of the central processor can be quickly transferred to the shell, and then the heat is dissipated to the outside of the shell through the heat dissipation fins.

[0009] The installation position of the above heat pipe in the housing is that an installation groove is provided on the inner side of the housing close to the heat dissipation fins. The heat pipe includes an integrally formed first pipe section and a second pipe section. The first pipe section is located between the heat dissipation surface and the inner side surface, and the second pipe section is arranged in the installation groove along the length direction of the installation groove. The second pipe section has the condensation section of the heat pipe, and the second pipe section is arranged in the installation groove that can facilitate the rapid transfer of the heat of the heat pipe to the housing.

[0010] The specific structure of the above heat dissipation support plate is that the heat dissipation support plate is an L-shaped plate. The L-shaped plate includes a long plate and a short plate that are vertically connected. The length direction of the long plate is the same as the length direction of the first pipe section, and the upper surface of the long plate is connected to the lower surface of the heat pipe through thermal conductive silicone.

[0011] Regarding the specific structure of the long plate, the width of the long plate is greater than the width of the heat pipe, which is convenient for supporting the heat pipe. And the length of the long plate is located within 1 / 3 - 2 / 3 of the length of the first pipe section, which can support the first pipe section within a certain length, improve the stability of the first pipe section, and transfer the heat of the first pipe section to the bottom plate of the housing.

[0012] The connection structure between the above L-shaped plate and the bottom plate is that a connecting plate is provided on the side of the short plate away from the heat dissipation copper seat. The connecting plate is located directly below the long plate and is detachably connected to the bottom plate through a connecting member. Such a setting of the position of the connecting plate can reduce the occupied space of the L-shaped plate on the bottom plate for installing other components of the UAV data transmission radio.

[0013] Regarding the specific structure of the fixing frame, a positioning groove is provided on the lower surface of the middle part of the fixing frame. The positioning groove is adapted to the first pipe section, the length direction of the positioning groove is the same as the length direction of the first pipe section, and both sides of the positioning groove are open.

[0014] To improve the heat dissipation effect of the heat dissipation surface of the central processing unit, at least two groups of heat pipes are provided. The evaporation sections of the two groups of heat pipes are arranged staggered on the heat dissipation surface, the condensation sections of the two groups of heat pipes are arranged in the reverse direction, and both extend towards the heat dissipation fins on both sides of the housing.

[0015] The arrangement positions of the above two groups of heat pipes are that the two groups of heat pipes have the same structure, and the first pipe sections of the two groups of heat pipes are arranged in parallel, which can be arranged in the same direction to avoid unreasonable arrangement positions of the two first pipe sections, occupying the internal space of the housing and affecting the installation of other components.

[0016] Regarding the setting position and specific structure of the heat dissipation fins, heat dissipation fins are provided on both sides of the housing along the length direction of the first pipe section. The heat dissipation fins include a plurality of heat dissipation grooves distributed up and down. The length direction of the heat dissipation grooves is the same as the length direction of the installation groove, and the cross section of the heat dissipation grooves is triangular.

[0017] The beneficial effects of the present utility model are as follows;

[0018] The evaporation section of the heat pipe is in contact connection with the heat dissipation surface of the central processing unit of the UAV data transmission radio through a heat dissipation copper seat. The heat dissipation copper seat and the heat dissipation surface can be connected through thermal conductive silicone. The heat dissipation copper seat has the function of heat conduction and dissipation, and can transfer the heat of the heat dissipation surface to the heat pipe, and then transfer the heat to the shell through the heat pipe, and dissipate the heat through the heat dissipation fins. The prior art is not convenient to transfer the heat of the central processing unit to the shell, and can only rely on the heat dissipation surface to dissipate the heat to the inside of the shell. The utility model can accelerate the dissipation of the heat inside the UAV data transmission radio to the outside of the shell;

[0019] The L-shaped plate can support the first pipe section within a certain length, improve the stability of the first pipe section, and can also transfer the heat of the first pipe section to the bottom plate of the shell, and assist in heat dissipation through the bottom plate to increase the heat dissipation area;

[0020] To improve the heat dissipation effect of the heat dissipation surface of the central processing unit, at least two groups of heat pipes are provided, and the evaporation sections of the two groups of heat pipes are staggered on the heat dissipation surface, which can transfer the heat inside the UAV data transmission radio to different positions of the shell and improve the heat dissipation effect.

Detailed Description of the Invention

[0027] See Figure 1 and Figure 2As shown in the figure, a heat dissipation device for a UAV data radio is arranged inside the housing 1 of the UAV data radio. A central processor 4 of the UAV data radio is provided inside the housing 1. Heat dissipation fins 2 are provided outside the housing 1. A heat pipe 3 is provided inside the housing 1. The heat pipe 3 includes a condensation section 321 and an evaporation section 311. The heat pipe 3 is a prior art. The evaporation section 311 is arranged on the heat dissipation surface of the central processor 4 through a heat dissipation copper seat 10. The heat dissipation copper seat 10 is in a plate-shaped structure. The lower surface of the heat dissipation copper seat 10 is connected to the heat dissipation surface through thermal conductive silicone. The upper surface of the heat dissipation copper seat 10 is in contact connection with the evaporation section 311 of the heat pipe 3. A fixing frame 5 is provided above the heat pipe 3. The middle part of the fixing frame 5 is clamped with the heat pipe 3. The two ends of the fixing frame 5 are detachably connected to the bottom plate 11 of the housing 1.

[0028] See Figure 3 As shown in the figure, the installation position of the above heat pipe 3 inside the housing 1 is that an installation groove 12 is opened on the inner side surface of the housing 1 close to the heat dissipation fins 2. The heat pipe 3 includes an integrally formed first pipe section 31 and a second pipe section 32. The first pipe section 31 is located between the heat dissipation surface and the inner side surface. The second pipe section 32 is arranged inside it along the length direction of the installation groove 12. The first pipe section 31 has an evaporation section 311. The second pipe section 32 has a condensation section 321 of the heat pipe 3. The second pipe section 32 is arranged in the available installation groove 12. The length direction of the second pipe section 32 can be consistent with the length direction of the installation groove 12, which is convenient for the heat of the heat pipe 3 to be quickly transferred to the housing 1.

[0029] See Figure 3 As shown in the figure, the specific structure of the above fixing frame 5 is that the fixing frame 5 includes a horizontal plate 51 and vertical plates 52 arranged at both ends of the horizontal plate 51. The horizontal plate 51 is arranged parallel to the bottom plate 11. The vertical plates 52 are vertically arranged on the bottom plate 11 and are connected to the bottom plate 11 through bolts. A positioning groove 511 is opened on the lower surface of the middle part of the horizontal plate 51. The positioning groove 511 is adapted to the first pipe section 31. The length direction of the positioning groove 511 is consistent with the length direction of the first pipe section 31. And both sides of the positioning groove 511 are open, which is convenient for directly clamping the positioning groove 511 on the upper part of the heat pipe 3 when fixing the heat pipe 3, avoiding the heat pipe 3 from detaching or shifting from the heat dissipation copper seat 10 and the heat dissipation surface due to the vibration of the UAV data radio. The length direction of the positioning groove 511 is consistent with the length direction of the first pipe section 31, which can play a limiting role in the width direction of the first pipe section 31.

[0030] See Figure 2As shown, the condensation section 321 at the other end of the heat pipe 3 extends inside the housing 1 towards the side close to the heat dissipation fins 2 and is connected to the inner side surface of the housing 1 close to the heat dissipation fins 2. The lower surface of the condensation section 321 is detachably connected to the bottom plate 11 through a heat dissipation support plate. The specific structure of the above heat dissipation support plate is that the heat dissipation support plate is an L-shaped plate, and the L-shaped plate includes a long plate 6 and a short plate 7 that are vertically connected. The length direction of the long plate 6 is the same as the length direction of the first pipe section 31. The upper surface of the long plate 6 and the lower surface of the heat pipe 3 are connected through thermal conductive silicone. Regarding the specific structure of the long plate 6, the width of the long plate 6 is greater than the width of the heat pipe 3, which is convenient for supporting the heat pipe 3. And the length of the long plate 6 is located within 1 / 3 - 2 / 3 of the length of the first pipe section 31, which can support the first pipe section 31 within a certain length, improve the stability of the first pipe section 31, and transfer the heat of the first pipe section 31 to the bottom plate 11 of the housing 1.

[0031] See Figure 2 As shown, the connection structure between the above L-shaped plate and the bottom plate 11 is that a connecting plate 8 is provided on the side of the short plate 7 away from the heat dissipation copper seat 10. The connecting plate 8 is located directly below the long plate 6 and is detachably connected to the bottom plate 11 through a connecting member 9. The connecting member 9 can be a connecting bolt. Such a setting of the position of the connecting plate 8 can reduce the occupied space of the L-shaped plate on the bottom plate 11 for installing other components of the UAV data transmission radio.

[0032] Regarding the setting position and specific structure of the heat dissipation fins 2, heat dissipation fins 2 are provided on both sides of the housing 1 along the length direction of the first pipe section 31. The heat dissipation fins 2 include a plurality of heat dissipation grooves 21 distributed up and down. Fins are formed between adjacent heat dissipation grooves 21. The length direction of the heat dissipation grooves 21 is the same as the length direction of the installation groove 12. The cross-section of the heat dissipation groove 21 is triangular, and the bottom surface of the triangle is the bottom surface of the heat dissipation groove 21, which can increase the heat dissipation area of the fins.

[0033] In this embodiment, to improve the heat dissipation effect of the heat dissipation surface of the central processing unit 4, at least two groups of heat pipes 3 are provided. The evaporation sections 311 of the two groups of heat pipes 3 are staggered on the heat dissipation surface. The condensation sections 321 of the two groups of heat pipes 3 are arranged in the opposite direction and both extend towards the heat dissipation fins 2 on both sides of the housing 1. The arrangement positions of the above two groups of heat pipes 3 are that the two groups of heat pipes 3 have the same structure, and the first pipe sections 31 of the two groups of heat pipes 3 are arranged in parallel, which can be arranged in the same direction, avoiding unreasonable setting positions of the two first pipe sections 31, occupying the space inside the housing 1, and affecting the installation of other components.
