Description

Technical Field

[0001] This utility model relates to the field of radar protection structure technology, and in particular to a millimeter-wave radar thermal protection structure for fire-fighting robots. Background Technology

[0002] Millimeter-wave radar is a type of radar that operates in the millimeter-wave band. Millimeter waves typically refer to the 30–300 GHz frequency range (wavelength 1–10 mm). Since the wavelength of millimeter waves falls between microwaves and centimeter waves, millimeter-wave radar combines some advantages of microwave radar and photoelectric radar. In autonomous driving, millimeter-wave radar sensors have become one of the mainstream detection sensors due to their moderate cost, strong environmental adaptability, and good long-range detection capabilities. Currently, millimeter-wave radar used in firefighting robots is generally mounted on the vehicle body. However, because firefighting robots operate in extremely high-temperature environments, these high temperatures can lead to increased radar measurement errors, signal transmission obstruction, and even damage. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a millimeter-wave radar thermal protection structure for firefighting robots, thereby solving the problems mentioned in the background art.

[0004] To solve the above problems, this utility model provides the following solution:

[0005] A heat protection structure for millimeter-wave radar used in firefighting robots includes a heat insulation shell 1, a heat dissipation plate 2, and a sealing plate 3;

[0006] The heat insulation shell 1 has an inner cavity 11;

[0007] The heat sink 2 has a rectangular groove with a radar mounting hole 22 inside. A first inlet 24 is provided at the corner of the rectangular groove away from the radar mounting hole 22. The heat sink 2 also has a cooling channel 23, a water inlet 32 ​​and a water outlet 33. Fixing holes 21 are provided around the heat sink 2.

[0008] The second inlet 31 on the sealing plate 3;

[0009] The heat sink 2 is fixed to the inner shell 6 of the robot through the fixing hole 21;

[0010] The portion of the heat insulation shell 1, excluding the inner cavity 11, is tightly attached to the inner side of the robot's outer shell 5 and is pressed and fixed by the heat dissipation plate 2. The sealing plate 3 is fixedly connected to the heat dissipation plate 2 by soldering.

[0011] The radar body 4 is installed in the inner cavity 11 of the heat insulation shell 1 and the rectangular groove of the heat dissipation plate 2.

[0012] The radar body 4 is fixedly connected to the heat sink 2 through the radar mounting hole 22;

[0013] The other end of the cable connected to the radar body 4 is connected to external equipment through the first inlet 24 and the second inlet 31 to ensure that the radar signal transmission and power supply functions are not affected.

[0014] Cooling water enters the cooling channel 23 through the inlet 32 ​​and flows out from the outlet 33, carrying away heat and achieving the heat dissipation function.

[0015] The material of the heat insulation shell 1 is quartz;

[0016] In high-temperature environments, the heat insulation shell 1 primarily serves to block external high temperatures, reducing heat transfer to the interior. Simultaneously, the cooling channel 23 in the heat sink 2 introduces water through the inlet 32. The water flows within the channel, absorbing heat from the heat sink 2, and then flows out from the outlet 33, carrying away the heat and achieving heat dissipation. The radar body 4 is mounted on the heat sink 2 through the radar mounting hole 22. With the combined effects of heat insulation and heat dissipation, it can maintain a suitable operating temperature range and operate normally. Connections to external equipment via cables ensure that radar signal transmission and power supply functions are not affected. The second cable inlet 31 on the sealing plate 3 and the sealing design of the entire protective structure prevent dust and moisture from entering, protecting the working environment of the radar body 4.

[0017] It includes a heat sink and a heat insulation shell. The heat insulation shell is located on the outside of the radar and has an inner cavity. The heat sink has a cooling channel on its inner side.

[0018] As a preferred embodiment, the inner cavity is arc-shaped, and a rectangular protrusion is provided on the side of the inner cavity near the water outlet, which can better adapt to the shape of the radar and make the heating more uniform, avoiding local overheating.

[0019] In a preferred embodiment, the heat sink is provided with multiple mounting holes around its perimeter and radar mounting holes inside the heat sink for easy installation.

[0020] As a preferred embodiment, a sealing plate is also included, which is disposed inside the heat sink plate and has an inlet and an outlet for sealing the cooling channel.

[0021] In a preferred embodiment, the sealing plate is also provided with a cable inlet hole, and the heat sink is also provided with a cable inlet hole that matches the sealing plate, which facilitates radar wiring and installation.

[0022] In a preferred embodiment, the cooling channels are distributed in a meandering pattern, which can increase the heat dissipation area and achieve uniform heat dissipation.

[0023] This utility model has the following beneficial effects:

[0024] This invention provides a thermal protection structure for millimeter-wave radar used in firefighting robots. When the firefighting robot operates in a high-temperature environment for extended periods, the heat-insulating shell provides thermal protection for the radar, allowing it to maintain a normal operating temperature range even under high-temperature conditions. This extends the radar's lifespan and reduces maintenance costs. Simultaneously, a meandering cooling channel further cools the radar, effectively dissipating heat accumulated within the protective structure and preventing overheating, thus ensuring stable radar operation. Water is introduced through the back of the heat sink for cooling, preventing the radar from overheating due to operational and environmental factors. The heat-insulating shell protects the radar from external high temperatures and impacts, maintaining it at its operating temperature and ensuring normal operation, thereby extending its lifespan.
