Description

Technical Field

[0001] This utility model belongs to the field of phased array antenna technology, and specifically relates to a heat dissipation structure for a tile-type phased array antenna and a tile-type phased array antenna. Background Technology

[0002] A phased array antenna is an antenna that changes its radiation pattern shape by controlling the feed phase of the radiating elements in the array. Controlling the phase can change the direction of the maximum radiation value of the antenna pattern to achieve beam scanning. Since a phased array antenna consists of a large number of active components and electronic devices, these components generate a lot of heat during operation, especially the receiving and transmitting antenna arrays. Therefore, a heat dissipation structure is required on the phased array antenna to ensure its continuous and stable operation.

[0003] Most existing phased array antennas use heat dissipation measures such as heat spreaders and liquid cooling to ensure their normal operation, but they have disadvantages such as high heat dissipation costs, complex overall structure, and large size, which cannot meet the increasing market demand.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a heat dissipation structure for a tile-type phased array antenna, including a support frame, a first heat dissipation duct, a second heat dissipation duct, a first fan, and a second fan.

[0007] Both the first and second heat dissipation ducts are located on the lower side of the support frame and penetrate the side wall of the support frame.

[0008] Furthermore, the receiving antenna array and the first heat dissipation tooth are vertically aligned, and the transmitting antenna array and the second heat dissipation tooth are vertically aligned.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0029] One embodiment of this utility model provides a heat dissipation structure for a tile-type phased array antenna, such as... Figures 1 to 3As shown, the heat dissipation structure includes a support frame 1, a first heat dissipation duct, a second heat dissipation duct, a first fan 2, and a second fan 3; wherein, the first fan and the second fan can be high-speed cooling fans, and the support frame can be made of aluminum alloy, which has the characteristics of good thermal conductivity, light weight, and high strength.

[0030] Specifically, both the first and second heat dissipation ducts are located on the lower side of the support frame 1 and penetrate the side wall of the support frame 1. That is, the first and second heat dissipation ducts are arranged parallel to the support frame 1. The air inlets of the first and second heat dissipation ducts are located on one side wall of the support frame 1, and the air outlets of the first and second heat dissipation ducts are located on the other side wall of the support frame 1. The first fan 2 is used to send air into the first heat dissipation duct to bring in low-temperature airflow from the outside for heat exchange. The second fan 3 is used to send air into the second heat dissipation duct to bring in low-temperature airflow from the outside for heat exchange.

[0031] Furthermore, the first heat dissipation duct is equipped with multiple first heat dissipation teeth 4 arranged along the airflow direction, meaning the length of the first heat dissipation teeth 4 is aligned with the airflow direction within the first heat dissipation duct. Similarly, the second heat dissipation duct is equipped with multiple second heat dissipation teeth 5 arranged along the airflow direction, meaning the length of the second heat dissipation teeth 5 is aligned with the airflow direction within the second heat dissipation duct. By providing the first heat dissipation teeth 4 and the second heat dissipation teeth 5, the contact area between the heat dissipation duct and the airflow can be increased, thereby improving the heat dissipation capacity of the heat dissipation structure. The number, area, and layout of the first and second heat dissipation teeth can be adjusted as needed.

[0032] In addition, the support frames 1 on both sides of the first heat dissipation duct and the support frames 1 on both sides of the second heat dissipation duct are used to arrange the frequency conversion module, receiving module, power supply module and control module of the phased array antenna. The upper side of the support frame 1 is used to arrange the receiving antenna array, transmitting antenna array and navigation antenna of the phased array antenna, so that the first heat dissipation duct and the second heat dissipation duct are embedded in the phased array antenna. In this way, the heat generated by the phased array antenna can be quickly conducted to the heat dissipation duct through the support frame 1, the first heat dissipation tooth 4 and the second heat dissipation tooth 5, and carried away by the low temperature fluid in the heat dissipation duct.

[0033] In summary, the heat dissipation structure of this embodiment, by setting up a closed embedded air duct combined with a fan, can achieve efficient heat dissipation of the phased array antenna, and greatly reduce the overall height and weight of the antenna. This results in a low profile, lightweight design, low production cost, and stable heat dissipation capacity, thus improving the antenna's integration. In addition, by setting up heat dissipation teeth, the heat dissipation area is increased, further improving the heat dissipation capacity of the heat dissipation structure and effectively ensuring the stability of the antenna's performance indicators.

[0034] In this embodiment, as Figure 1 and Figure 3 As shown, the positions of the receiving antenna array and the first heat dissipation tooth 4 are vertically aligned, and the positions of the transmitting antenna array and the second heat dissipation tooth 5 are vertically aligned. Since the receiving antenna array and the transmitting antenna array are the main heat-generating components of the phased array antenna, the above-mentioned structural arrangement can ensure that most of the heat generated by the phased array antenna can be quickly conducted into the heat dissipation duct and carried away by the low-temperature fluid, making the heat dissipation efficiency of the heat dissipation structure higher.

[0035] Furthermore, such as Figure 1 As shown, multiple first grooves 6 and multiple second grooves 7 are formed on the upper side of the support frame 1. These grooves are arranged in an array. The first grooves 6 accommodate the thermal pads of the receiving antenna array, and the second grooves 7 accommodate the thermal pads of the transmitting antenna array. It should be noted that both the receiving and transmitting antenna arrays are composed of power chips. When fixing the power chips to the support frame 1, thermal pads need to be placed between the power chips and the support frame 1 to allow the heat generated by the power chips to be quickly conducted to the support frame 1. The placement of the first grooves 6 and second grooves 7 not only facilitates the positioning of the thermal pads but also increases the contact area between the thermal pads and the support frame 1, resulting in higher heat conduction efficiency.

[0036] In this embodiment, as Figure 2 and Figure 3 As shown, the heat dissipation structure for the Watt phased array antenna includes a first air duct cover plate 8, a second air duct cover plate 9, two first isolation plates 10, and two second isolation plates 11.

[0037] Specifically, the first air duct cover 8, the two first isolation plates 10, and the lower side of the support frame 1 constitute the first heat dissipation air duct. The first air duct cover 8 is fixed to the first isolation plate 10 with screws, and each first heat dissipation tooth 4 is provided on the lower side of the support frame 1. The second air duct cover 9, the two second isolation plates 11, and the lower side of the support frame 1 constitute the second heat dissipation air duct. The second air duct cover 9 is fixed to the second isolation plate 11 with screws, and each second heat dissipation tooth 5 is provided on the lower side of the support frame 1. The first and second heat dissipation air ducts are detachable, facilitating cleaning and maintenance. Both the first and second isolation plates can be integrally integrated with the support frame.

[0038] Furthermore, each of the first and second heat dissipation fins is integrally integrated with the support frame, making the heat dissipation structure easier to manufacture and reducing its manufacturing cost. Alternatively, in other embodiments, each of the first and second heat dissipation fins is a separate component from the support frame, meaning the first and second heat dissipation fins are manufactured separately and then welded onto the support frame.

[0039] In addition, such as Figure 2 and Figure 3As shown, the first fan 2 is located at the air inlet of the first heat dissipation duct, and a first dust cover 12 is provided on the air inlet side of the first fan 2. The second fan 3 is located at the air inlet of the second heat dissipation duct, and a second dust cover 13 is provided on the air inlet side of the second fan 3. The dust cover not only protects the fan, but also prevents dust and lint from entering the duct when the fan draws in outside air.

[0040] In this embodiment, the heat dissipation structure for the Watt phased array antenna also includes an antenna radome (not shown in the figure) and a base plate (not shown in the figure).

[0041] Specifically, the radome is fixed to the upper side of the support frame to protect the receiving antenna array, transmitting antenna array, and navigation antenna on the upper side of the support frame, while the base plate is fixed to the lower side of the support frame to seal and protect the antenna module on the lower side of the support frame.

[0042] Furthermore, such as Figures 1 to 3 As shown, the inner side wall of the support frame 1 is provided with multiple screw-hole posts 14, each with screw holes. The radome and the base plate are fixed to the support frame 1 through the screw holes and screws / bolts. The screw-hole posts 14 not only provide internal fixing positions for the radome and the base plate, making the appearance of the heat dissipation structure more regular and concise, but also enhance the strength of the side wall of the support frame 1.

[0043] In addition, such as Figures 1 to 3 As shown, the support frame 1 has multiple pipeline holes 15 on its side wall. The pipeline holes 15 are used for the antenna wire harness to pass through the heat dissipation structure. Of course, the pipeline holes 15 can also be used to fix the antenna wire harness connector or wire harness connector base.

[0044] Another embodiment of this utility model provides a watt-type phased array antenna, specifically including a navigation antenna, a receiving antenna array, a transmitting antenna array, and the heat dissipation structure for the watt-type phased array antenna in the above embodiment.

[0045] The navigation antenna, receiving antenna array, and transmitting antenna array are all arranged on the upper side of the support frame. This watt-type phased array antenna has advantages such as low profile, lightweight, low production cost, stable heat dissipation, and high integration, thus possessing high adaptability to multiple platforms and high market competitiveness.

[0046] The above description is merely a specific embodiment of this utility model. Under the teachings of this utility model, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this utility model, and the scope of protection of this utility model should be determined by the scope of the claims.
