Description

Technical Field

[0001] This invention relates to the field of radar chassis technology, and in particular to a transceiver chassis mounted on a radar antenna mount and a heat dissipation method thereof. Background Technology

[0002] With the rapid development of information technology and electronic technology, the types and quantities of components that make up radar enclosures are increasing, but the requirements for size and weight are getting smaller, the scope of use is getting wider, the working environment is getting more complex, and the requirements for the precision and reliability of the equipment are getting higher. Therefore, radar enclosure structure design has developed into a comprehensive application technology involving multiple disciplines such as mechanics, thermodynamics, electrical engineering, and materials.

[0003] Currently, traditional radar enclosures primarily use aluminum sheet metal assembly or cast aluminum milling to ensure the structural strength and light weight requirements; additionally, the good thermal conductivity of aluminum enclosures is used to meet heat dissipation requirements. However, due to space limitations on the antenna mount, it is often necessary to make separate enclosures for receiving and transmitting; and to achieve the purposes of use and maintenance, sheet metal components are usually required to create transition interfaces, resulting in complex door panel structures and demanding sealing structures, which contributes to the high overall weight of the enclosure. Summary of the Invention

[0004] To address the shortcomings of existing manufacturing technologies, the applicant provides a radar antenna mount transceiver chassis and its heat dissipation method. By rationally distributing the internal space, the transmitting and receiving modules are integrated and installed inside the chassis, and a layered structure with double hinges is used to achieve orderly disassembly and maintenance of each component. At the same time, the formed inner frame unit enables the introduced cold air to be concentrated on dissipating heat from the main heat source, the transmitting module, preventing the cold air from spreading into other cavities and affecting the heat dissipation efficiency, thus greatly improving the heat dissipation efficiency of the entire chassis.

[0005] The technical solution adopted in this invention is as follows: A transceiver chassis mounted on a radar antenna mount includes upper and lower matching outer shell units and a base. An inner frame unit is mounted on the base. The inner frame unit is a cavity structure with an open front end, and is sequentially divided from bottom to top to form a bottom mounting cavity, a middle cooling cavity, and a top mounting cavity. A polarization module is assembled in the bottom mounting cavity, a transmitting module is assembled in the middle cooling cavity, and a receiving module, a power supply module, and a digital receiver are assembled on the top mounting cavity. An air duct is provided at the rear end of the inner frame unit, and the air duct faces the middle cooling cavity. A fan mounting base is provided on the air inlet side of the air duct, and a fan is mounted on the fan mounting base. The fan sends cold air into the middle cooling cavity through the air duct.

[0006] As a further improvement to the above technical solution:

[0007] Preferably, the inner frame unit has the following structure: it includes a first vertical plate and a second vertical plate arranged vertically at intervals, the tops of the first vertical plate and the second vertical plate are connected by a top plate, and the first vertical plate, the second vertical plate and the top plate together form a “┏┓” frame structure; a partition plate parallel to the top is installed horizontally between the first vertical plate and the second vertical plate; the cavity between the bottom of the partition plate and the top of the base is a bottom mounting cavity; the cavity between the top of the partition plate and the bottom of the top plate is a middle cooling cavity; and the cavity between the top of the top plate and the outer shell unit is a top mounting cavity.

[0008] Preferably, a baffle is provided at the rear end of the inner frame unit. The baffle has the following structure: a first baffle arranged horizontally, a second baffle arranged above one side of the first baffle, and a third baffle arranged above the other side; the through window formed between the second baffle and the third baffle is an air guide.

[0009] Preferably, the bottom surface of the top plate is evenly distributed with grooves, and heat dissipation teeth are installed below the top plate; the heat dissipation teeth and the grooves in the middle match each other to form a ventilation cavity.

[0010] Preferably, the bottom mounting cavity has vent holes on both sides, and the middle cooling cavity has rectangular grooves on both sides.

[0011] Preferably, a second hinge is provided at the connection between the top plate and the second vertical plate.

[0012] Preferably, the structure of the outer shell unit is as follows: it includes a shell, a door panel is installed on the top of the shell, an air inlet is provided at the bottom of the shell, and air outlets are provided on both sides of the top of the shell; cold air is introduced from the air inlet by a fan and passes through the central cooling cavity to exchange heat with the transmitting module, and after the heat exchange is completed, it passes out from the air outlet.

[0013] Preferably, a first hinge is provided at the connection between one side of the door panel and the housing, and a sealing strip is provided at the contact end between the lower part of the door panel and the housing.

[0014] Preferably, multiple fan mounting bases are evenly distributed along the horizontal direction, and each fan mounting base is equipped with a fan.

[0015] Preferably, the outer casing unit is installed with the base via a snap-fit ​​mechanism.

[0016] A method for heat dissipation of a transceiver chassis mounted on a radar antenna mount, comprising the following steps:

[0017] Step 1: Turn on the fan to draw in cool air from outside through the air inlet;

[0018] Step 2: Install a baffle on the air outlet side of the fan. The baffle blocks the bottom mounting cavity, forming a "┕┙" shaped structure that is high on both sides and low in the middle, so that the air guide is directly facing the central cooling cavity.

[0019] Step 3: The fan draws in external cold air, which can only enter the central cooling chamber through the air vent;

[0020] Step 4: The cold air entering the central cooling chamber cools the internal launch module;

[0021] Step 5: The cold air is also guided by the toothed grooves, heat dissipation teeth and rectangular grooves in the central cooling cavity, increasing the heat dissipation area in the central cooling cavity.

[0022] Step Six: After completing the heat exchange with the launch module, the cool air flows out from the opening at the front of the inner frame unit and finally exits from the air outlet on the outer shell unit.

[0023] The beneficial effects of this invention are as follows:

[0024] This invention features a compact and rationally distributed structure. An outer frame is formed by an outer shell unit and a base, while an inner frame unit is set on the base to form an inner frame. The cavities of the inner frame are divided to form three independent spatial cavities. This allows for the application of a rational spatial division principle for layout and installation, and a baffle is matched at the rear end. This not only improves space utilization but also directs the air inlet to the central cooling cavity through the baffle, forcing air cooling to act directly on the core heat source components. The cool air is not dispersed, and the heat dissipation efficiency is greatly improved.

[0025] The present invention also has the following advantages:

[0026] (1) Multiple fans are arranged horizontally on the outer side of the baffle of the present invention, while the baffle has only one air guide opening facing the central cooling cavity. In this way, the cold air introduced from the outside by multiple fans is introduced into the central cooling cavity through the air guide opening, which greatly increases the cold air flow rate and further improves the cooling effect.

[0027] (2) The present invention has evenly distributed toothed grooves on the bottom plate surface of the top plate, and heat dissipation teeth are installed below the top plate. The heat dissipation teeth and the toothed grooves in the middle match each other to form a ventilation cavity. At the same time, rectangular grooves are also provided on both sides of the central cooling cavity. After the cold air is introduced into the central cooling cavity, it will pass through the toothed grooves, ventilation cavity and rectangular grooves to increase the heat dissipation area.

[0028] (3) The present invention provides a first hinge at the connection between the door panel and the shell, the outer shell unit and the base are connected by a snap fastener, and a second hinge is provided at the connection between the top plate and the second vertical plate so that the inner frame unit can be opened by the hinge when needed, which facilitates daily inspection and maintenance, and greatly improves the maintainability of the product.

[0044] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0045] like Figures 1 to 11As shown, the radar antenna mount in this embodiment is equipped with a transceiver chassis, including an upper and lower matching outer shell unit 1 and a base 2. An inner frame unit 3 is mounted on the base 2. The inner frame unit 3 is a cavity structure with an open front end, and is divided into a bottom mounting cavity, a middle cooling cavity, and a top mounting cavity from bottom to top. A polarization module 4 is assembled in the bottom mounting cavity, a transmitting module 5 is assembled in the middle cooling cavity, and a receiving module 6, a power module 7, and a digital receiver 8 are assembled on the top mounting cavity. An air duct 11 is provided at the rear end of the inner frame unit 3. The air duct 11 faces the middle cooling cavity. A fan mounting seat 9 is provided on the air inlet side of the air duct 11, and a fan 10 is mounted on the fan mounting seat 9. The fan 10 sends cold air into the middle cooling cavity through the air duct 11.

[0046] In this embodiment, the inner frame unit 3 has the following structure: it includes a first vertical plate 301 and a second vertical plate 302 arranged vertically at intervals. The tops of the first vertical plate 301 and the second vertical plate 302 are connected by a top plate 303. The first vertical plate 301, the second vertical plate 302, and the top plate 303 together form a “┏┓” frame structure. A partition plate 304 parallel to the top plate 303 is installed horizontally between the first vertical plate 301 and the second vertical plate 302. The cavity between the bottom of the partition plate 304 and the top of the base 2 is the bottom mounting cavity. The cavity between the top of the partition plate 304 and the bottom of the top plate 303 is the middle cooling cavity. The cavity between the top of the top plate 303 and the outer shell unit 1 is the top mounting cavity. Through the cooperation of the inner frame unit 3 and the base 2, three independent spatial cavities are formed, which greatly improves the space utilization rate.

[0047] In this embodiment, a baffle 305 is provided at the rear end of the inner frame unit 3. The structure of the baffle 305 is as follows: a first baffle 30501 is arranged horizontally, a second baffle 30502 is arranged above one side of the first baffle 30501, and a third baffle 30503 is arranged above the other side; the through window formed between the second baffle 30502 and the third baffle 30503 is an air guide 11.

[0048] In this embodiment, the bottom plate surface of the top plate 303 is evenly distributed with toothed grooves 306, and heat dissipation teeth 307 are installed below the top plate 303; the heat dissipation teeth 307 and the toothed grooves 306 in the middle match each other and form a ventilation cavity; the bottom mounting cavity is provided with relief holes 308 on both sides, and the middle cooling cavity is provided with rectangular grooves 309 on both sides.

[0049] like Figure 1 As shown, in this embodiment, a second hinge 310 is provided at the connection between the top plate 303 and the second vertical plate 302. When needed for actual work, the top plate 303 can be opened through the second hinge 310 for easy maintenance.

[0050] In this embodiment, the structure of the outer shell unit 1 is as follows: it includes a shell 101, a door panel 102 is installed on the top of the shell 101, an air inlet 106 is provided at the bottom of the shell 101, and air outlets 107 are provided on both sides of the top of the shell 101; cold air is introduced from the air inlet 106 by the fan 10 and passes through the central cooling cavity to exchange heat with the transmitting module 5. After the heat exchange is completed, it passes out from the air outlet 107; a first hinge 103 is provided at the connection between one side of the door panel 102 and the shell 101, and a sealing strip 104 is provided at the contact end between the lower part of the door panel 102 and the shell 101, which improves the sealing of the interior of the outer shell unit 1, prevents cold air from passing out from the top after being introduced, and further restricts the flow direction of cold air.

[0051] In this embodiment, multiple fan mounting bases 9 are evenly distributed along the horizontal direction, and each fan mounting base 9 is equipped with a fan 10. Multiple fans 10 work at the same time, which greatly improves the efficiency of cold air introduction. Furthermore, since the baffle 305 has an air guide 11 facing the central cooling cavity, all the cold air introduced by the fan 10 enters the central cooling cavity from the air guide 11, thus limiting the direction of cold air flow.

[0052] In this embodiment, the outer shell unit 1 and the base 2 are installed together by a snap fastener 105. When maintenance is required, the outer shell unit 1 can be opened directly through the snap fastener 105 to facilitate observation and repair of the internal structure.

[0053] like Figure 11 As shown, in this embodiment, the heat dissipation method of the present invention is as follows:

[0054] The steps are as follows:

[0055] Step 1: Turn on the fan 10 to introduce external cold air through the air inlet 106;

[0056] Step 2: Install a baffle 305 on the air outlet side of the fan 10. The baffle 305 blocks the bottom mounting cavity, forming a "┕┙" shaped structure with high sides and low middle, so that the air guide 11 is directly facing the middle cooling cavity.

[0057] Step 3: Fan 10 introduces external cold air, which can only enter the central cooling chamber through air vent 11;

[0058] Step 4: The cold air entering the central cooling chamber cools the internal transmitting module 5;

[0059] Step 5: The cold air is also guided by the toothed grooves 306, heat dissipation teeth 307 and rectangular grooves 309 in the central cooling cavity, increasing the heat dissipation area in the central cooling cavity.

[0060] Step 6: After completing the heat exchange with the launch module 5, the cold air flows out from the opening at the front end of the inner frame unit 3 and finally exits from the air outlet 107 on the outer shell unit 1.

[0061] In this embodiment, for example, the air outlet 107 can be a louver structure.

[0062] The present invention has a reasonable structure and a reasonable distribution of internal space. The outer frame is formed by the outer shell unit 1 and the base 2, and the inner frame unit 3 is set on the base 2 to form the inner frame. The cavity of the inner frame is divided to form three independent spatial cavities, thereby applying the principle of reasonable space division for layout and installation, which greatly improves the space utilization rate. At the same time, the present invention also installs a baffle 305 on the air inlet side of the inner frame unit 3, so that the air guide 11 is directly facing the central cooling cavity, which limits the flow direction of the cold air and directly acts on the core heat source device, namely the emitting module 5. The cold air will not be dispersed in the central cooling cavity, and the heat dissipation efficiency is greatly improved.
