Description

Technical Field

[0001] This utility model relates to the field of power supply for laser wind measurement radar, specifically a power supply device for airborne laser wind measurement radar. Background Technology

[0002] In the aviation field, airborne laser wind radar plays a crucial role in acquiring accurate meteorological data, ensuring flight safety, and improving flight efficiency. The power supply unit, as the energy source for the stable operation of the laser wind radar, directly affects the reliability of the radar's operation.

[0003] Traditional airborne laser wind radar power supplies have many shortcomings. In outdoor conditions, the power supply will experience different ambient temperatures, and the charging and discharging performance of the battery is easily affected by temperature. If the power supply lacks effective thermal management measures, the battery may overheat in high-temperature environments, leading to battery capacity decay, reduced charging and discharging efficiency, and even safety hazards. In low-temperature environments, the battery's internal resistance increases, and its charging and discharging performance deteriorates, making it unable to provide sufficient power to the laser wind radar and seriously affecting the normal operation of the radar. Therefore, it is necessary to design an airborne laser wind radar power supply to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a power supply device for an airborne laser wind measuring radar to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power supply device for an airborne laser wind measuring radar, comprising a housing, wherein heat-conducting blocks are installed through both sides of the housing, and multiple heat dissipation fins are installed on the outer side of the heat-conducting blocks, and a heat-conducting pad is provided on the side of the heat-conducting blocks that passes through the housing.

[0006] The housing cavity contains two battery bodies. The housing cavity is equipped with two drive components for moving the battery bodies. A baffle is installed on one side of each battery body. Multiple second heat dissipation holes are opened on one side of the housing. The baffle is used to block the second heat dissipation holes. A heating component is installed in the middle of the housing cavity.

[0007] Preferably, a cover is installed on the top surface of the housing.

[0008] Preferably, the thermal pad is bonded to the surface of the thermal block, and the thermal pad is made of silicone material.

[0009] Preferably, the drive assembly includes an electric push rod, the outer rod of which is installed on one side of the inner cavity of the housing, and a connecting block is installed at one end of the inner rod of the electric push rod, the connecting block being fixed to the battery body.

[0010] Preferably, a plurality of first heat dissipation holes are provided on one side of the housing, and the connecting block is used to block the first heat dissipation holes.

[0011] Preferably, the heating element is a T-shaped contact plate, and a heating wire is disposed inside the T-shaped contact plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The power supply device for this airborne laser wind measuring radar, when the ambient temperature is high, controls the electric push rod to retract, driving the connecting block to move. The connecting block drives the battery body and the baffle to move. The connecting block moves to a position that does not block the first heat dissipation hole, and the baffle moves to a position that does not block the second heat dissipation hole, thereby promoting ventilation and heat dissipation inside the casing. One side of the battery body moves to a position that contacts the thermal pad. The heat generated by the battery body is conducted to the surface of the heat dissipation fins through the thermal pad and thermal block, which helps the battery body to dissipate heat quickly and ensures the charging and discharging efficiency of the battery body.

[0014] 2. The power supply device for this airborne laser wind radar, when the ambient temperature is low, controls the extension of the electric push rod, causing the connecting block, battery body and baffle to move. The connecting block moves to the position blocking the first heat dissipation hole, and the baffle moves to the position blocking the second heat dissipation hole, thereby reducing the airflow inside the casing and helping to keep the temperature. The battery body moves to the position of contacting the surface of the T-shaped contact plate, and the two battery bodies are in close proximity. The heat generated by the T-shaped contact plate can increase the temperature of the battery body, which helps to improve the temperature of the battery body and ensure the charging and discharging efficiency of the battery body.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides a power supply device for an airborne laser wind measuring radar, including a housing 1, heat-conducting blocks 3 are installed through both sides of the housing 1, multiple heat dissipation fins 4 are installed on the outside of the heat-conducting blocks 3, a heat-conducting pad 5 is provided on the side of the heat-conducting blocks 3 that passes through the inside of the housing 1, and a cover 2 is installed on the top surface of the housing 1.

[0022] The inner cavity of the housing 1 is provided with two battery bodies 6. The inner cavity of the housing 1 is equipped with two drive components for moving the battery bodies 6. A baffle 10 is installed on one side of the battery body 6. Multiple second heat dissipation holes 11 are opened on one side of the housing 1. The baffle 10 is used to block the second heat dissipation holes 11. A heating component is installed in the middle of the inner cavity of the housing 1.

[0023] Specifically, the heat-conducting block 3, heat dissipation fins 4, and heat-generating components facilitate the heating and cooling of the battery body 6, ensuring that the battery body 6 is maintained within a reasonable charging and discharging temperature range.

[0024] Among them: the thermal pad 5 is bonded to the surface of the thermal block 3. The thermal pad 5 is made of silicone material. The thermal pad 5 can conduct the heat of the battery body 6 to the thermal block 3, which helps to dissipate heat through the heat dissipation fins 4.

[0025] The drive assembly includes an electric push rod 7. The outer rod of the electric push rod 7 is installed on one side of the inner cavity of the housing 1. A connecting block 8 is installed at one end of the inner rod of the electric push rod 7. The connecting block 8 is fixed to the battery body 6. Multiple first heat dissipation holes 9 are opened on one side of the housing 1. The connecting block 8 is used to block the first heat dissipation holes 9. The extension and retraction of the electric push rod 7 can drive the connecting block 8 and the battery body 6 to move, thereby facilitating the change of the position of the battery body 6. When heat dissipation of the battery body 6 is required, the connecting block 8 moves to a position that does not block the first heat dissipation holes 9, promoting air circulation and heat dissipation inside the housing 1. When heat preservation is required, the connecting block 8 moves to a position that blocks the first heat dissipation holes 9.

[0026] Specifically, the heating component is a T-shaped contact plate 12, which has a heating wire inside. The heating wire generates heat, which raises the temperature of the T-shaped contact plate 12 and then heats the battery body 6 that is in contact with the T-shaped contact plate 12.

[0027] Working principle: This utility model is a power supply device for an airborne laser wind measuring radar. When the ambient temperature is high, the electric push rod 7 is controlled to retract, which drives the connecting block 8 to move. The connecting block 8 drives the battery body 6 and the baffle 10 to move. The connecting block 8 moves to a position that does not block the first heat dissipation hole 9, and the baffle 10 moves to a position that does not block the second heat dissipation hole 11, thereby promoting ventilation and heat dissipation inside the housing 1. One side of the battery body 6 moves to a position that contacts the heat-conducting pad 5. The heat generated by the battery body 6 is conducted to the surface of the heat dissipation fins 4 through the heat-conducting pad 5 and the heat-conducting block 3, which helps the battery body 6 to dissipate heat quickly and ensures the charging and discharging efficiency of the battery body 6.

[0028] When the ambient temperature is low, the electric push rod 7 is extended, causing the connecting block 8, battery body 6 and baffle 10 to move. The connecting block 8 moves to the position of blocking the first heat dissipation hole 9, and the baffle 10 moves to the position of blocking the second heat dissipation hole 11, thereby reducing the air flow inside the housing 1 and helping to keep the temperature. The battery body 6 moves to the position of contacting the surface of the T-shaped contact plate 12. Since the two battery bodies 6 are in close proximity, the heat generated by the T-shaped contact plate 12 can increase the temperature of the battery body 6, which helps to improve the temperature of the battery body 6 and ensure the charging and discharging efficiency of the battery body 6.
