Description
TECHNICAL FIELD
[0001] The utility model relates to antenna thermal management technical field especially relates to a TR module's heat management radiating assembly. BACKGROUND
[0002] Phased array antenna refers to the antenna that changes the shape of the radiation pattern by controlling the feeding phase of the radiating unit in the array antenna. Controlling the phase can change the pointing of the antenna pattern maximum value to achieve the purpose of beam scanning. At present, phased array antennas are more and more widely used in JS and civil applications, and there are hundreds of TR components distributed on an antenna array surface. In the aircraft environment, they are arranged compactly, the heat dissipation space is small, and the system integration coupling degree is high, which makes the heat flux density of the antenna array surface very large. If these heat cannot be taken away from the antenna array surface in time, the temperature of the antenna array surface will rise, causing the performance of the T / R component to decline or even fail, and even the components in the TR component may be burned out, thereby affecting the normal operation of the entire system. At present, liquid cooling plates are used to cool the TR components of the antenna, and the liquid cooling plate is attached to the TR component for heat dissipation. This heat dissipation method is limited by the contact area of the liquid cooling plate and the TR component, and it is difficult to further improve the heat dissipation efficiency, so it needs to be improved.

[0016] As Figs. 1-3As shown, a thermal management and heat dissipation component of a TR module includes a TR module 100, a fan 1, a radiator 2, several liquid cooling pipes 3, a liquid cooling plate 4 and a clamp 5. The fan 1 is installed on the radiator 2, and one end of several liquid cooling pipes 3 passes through the radiator 2 in parallel and spaced apart. The other end of the liquid cooling pipe 3 is connected to the liquid cooling plate 4. The liquid cooling plate 4 is provided with several heat conducting fins 41 on the side facing away from the liquid cooling pipe 3. The heat conducting fins 41 are inserted into the TR module 100. The outer ring of the TR module 100 is locked by the clamp 5, and the clamp 5 is detachably connected to the edge of the liquid cooling plate 4. Specifically, in this embodiment, the TR module 100 is a chip package, and one end of the TR module 100 is released from the liquid cooling plate 4. When the coolant circulates in the liquid cooling plate 4, it can take away the heat conducted by the TR module 100. In order to improve the heat dissipation efficiency, it is necessary to increase the contact area between the liquid cooling plate 4 and the TR module 100. We have provided a plurality of heat-conducting fins 41 on the plate surface of the liquid cooling plate 4. The heat-conducting fins 41 are inserted into the TR module 100. In order to ensure good contact between the inner side wall of the TR module 100 and the heat-conducting fins 41 and avoid gaps, we use a clamp 5 to lock the periphery of the TR module 100, and the clamp 5 is also connected to the liquid cooling plate 4 by bolts, so that the TR module 100 is tightly fixed on the liquid cooling plate 4, with good stability. The liquid cooling plate 4 is connected to the radiator 2 through the liquid cooling pipe 3. The liquid cooling pipe 3 is integrated with a circulation pump for pumping coolant. When the coolant circulates between the liquid cooling pipe 3 and the liquid cooling plate 4, it can transport the heat generated by the TR module 100. When the heat is transported to the radiator 2, the fan 1 is started to take away the heat in the radiator 2, completing the cooling process of the TR module 100.
[0017] like Figs. 1-3 As shown, the heat sink 2 includes an outer frame 21 and a plurality of heat dissipation fins 22. The heat dissipation fins 22 are installed side by side and spaced apart on one side of the outer frame 21. The fan 1 is installed on the other side of the outer frame 21. The airflow direction of the fan 1 is in the same direction as the extension direction of the heat dissipation fins 22. Specifically, when the fan 1 is started, the airflow flows through the plate surface of the heat dissipation fins 22, thereby removing the heat accumulated therein and improving the heat dissipation efficiency.
[0018] like Figs. 1-3 As shown, the TR module 100 has a notch 101 on the side facing the liquid cooling plate 4, and the thermal fins 41 are inserted into the notch 101. Specifically, the notch 101 matches the thermal fins 41 to increase the contact area between the TR module 100 and the liquid cooling plate 4, and ensure that the contact surface between the TR module 100 and the liquid cooling plate 4 remains flat, with high integration and good stability.
[0019] Specifically, a flow-disturbing spike is further provided in the liquid cooling plate 4. If the flow-disturbing spike passes through the liquid cooling plate 4, the coolant will flow disorderly when flowing in the liquid cooling plate 4, thereby improving the heat exchange efficiency.
[0020] As shown in Figs. 1-3 The four-corner positions of the liquid cooling plate 4 are provided with fixing ears 43, and the bolts pass through the clamps 5 and are connected with the fixing ears 43, specifically, the clamps 5 are connected with the fixing ears 43 at the four-corner positions of the liquid cooling plate 4, so that the metal connecting pieces are avoided to be integrated on the TR module 100, and the weight is reduced.
[0021] The above-mentioned embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
