Description

Technical Field

[0001] The invention belongs to the technical field of communication equipment and relates to a heat dissipation device of a radar cabinet, in particular to a heat dissipation system of a parallel radar cabinet. Background Art

[0002] Cabinets are a crucial component of radar systems, housing back-end data processing equipment and providing a cooling environment for electronic equipment, ensuring they operate within their permissible operating temperature range. Existing cabinets are typically placed within shelters or computer rooms. They draw in cool air from the shelter or computer room environment, exchange heat with the electronic equipment within, and then exhaust the heated air directly back into the shelter or computer room, dissipating the heat.

[0003] With the rapid development of radar phased array technology, the number of back-end data processing devices is increasing, and the heat flux density of each device is also increasing, which requires increasingly higher heat dissipation efficiency and reliability. In addition, because cabinets are often located in the same cabin or computer room as operators, traditional cabinet cooling structures lack dedicated cold and hot air ducts. The fans generate high fan noise when air is drawn in or out, and the hot air after heat exchange is directly discharged into the cabin or computer room, potentially blowing directly at the operators, causing uneven internal ambient temperature and affecting the operator's work experience. Summary of the Invention

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes a parallel radar cabinet cooling system. Through independent air duct design and dynamic air volume adjustment, it solves the problems of low heat dissipation efficiency, high noise and hot air affecting the operating environment of traditional cabinets.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] like Figure 1As shown, the present invention provides a parallel radar cabinet cooling system, comprising: an air cavity cabinet 1 and two parallel cabinets 2. In actual use, the number of air cavity cabinets 1 and parallel cabinets 2 can be reasonably selected according to actual conditions. In this embodiment, the air cavity cabinet 1 is arranged between the two parallel cabinets 2, and the electronic equipment is installed in the inner cavity of the two parallel cabinets 2. The air cavity cabinet 1 simultaneously introduces cold air into the two parallel cabinets 2 and discharges the hot air generated after heat exchange in the two parallel cabinets 2, thereby achieving cooling and heat dissipation of the electronic equipment in the parallel cabinet 2.

[0032] like Figure 2-3 As shown, the inner cavity of the air cavity cabinet 1 is divided into a cold air channel 12 and a hot air channel 13 by a partition 11. The cold air channel 12 of the air cavity cabinet 1 is directly connected to the air outlet of the cabin or computer room air conditioner through a pipe from the top surface to supply cold air into the cold air channel 12. The hot air channel 13 of the air cavity cabinet 1 is directly connected to the external exhaust port of the cabin or computer room through a pipe from the top surface to discharge the hot air in the hot air channel 13. Cold air outlets 14 and hot air inlets 15 are provided on the left side wall and the right side wall of the air cavity cabinet 1. The cold air outlet 14 is connected to the cold air channel 12, and the hot air inlet 15 is connected to the hot air channel 13.

[0033] The cold air outlets 14 on the left and right sides of the air chamber cabinet 1 are each equipped with a set of electric shutters. The opening angle of the electric shutters can be adjusted from 0 degrees to 90 degrees to achieve precise control of the cold air output volume. The opening angle of the electric shutters on the left and right sides of the air chamber cabinet 1 is independently adjusted via an angle control switch. The hot air inlet 15 on the left and right sides of the air chamber cabinet 1 is each equipped with a fan array consisting of multiple fans. The fan speed can be adjusted from 500 rpm to 3000 rpm to achieve precise control of the hot air inlet volume. The fan speed on the left and right sides of the air chamber cabinet 1 is independently adjusted via a speed control switch. The two angle control switches and the two speed control switches are both mounted on the control panel 17 on the side wall of the air chamber cabinet 1.

[0034] like Figure 4 As shown, the parallel cabinet 2 is connected to the left / right side of the air cavity cabinet 1, and two opposite first mounting interfaces 16 are provided on the left and right side walls of the air cavity cabinet 1. Two opposite second mounting interfaces 23 are provided on the side wall on which the parallel cabinet 2 is connected to the air cavity cabinet 1. The second mounting interface 23 of the parallel cabinet 2 is adapted to be docked with the first mounting interface 16 of the air cavity cabinet 1 and fixed by bolts to realize the assembly of the air cavity cabinet 1 and the parallel cabinet 2.

[0035] A cold air inlet 21 and a hot air outlet 22 are provided on the side wall of the parallel cabinet 2. When the parallel cabinet 2 is connected and fixed to the air cavity cabinet 1, the cold air outlet 14 of the air cavity cabinet 1 is adapted to be connected with the cold air inlet 21 of the parallel cabinet 2, so that the cold air in the cold air channel 12 of the air cavity cabinet 1 enters the parallel cabinet 2 through this, and the hot air outlet 22 of the parallel cabinet 2 is adapted to be connected with the hot air inlet 15 of the air cavity cabinet 1, so that the hot air in the parallel cabinet 2 is discharged into the hot air channel 13 of the air cavity cabinet 1 through this.

[0036] In particular, the two opposite first mounting interfaces 16 on the air cavity cabinet 1 are respectively arranged on the outside of the cold air outlet 14 and the hot air inlet 15. Correspondingly, the two opposite second mounting interfaces 23 on the parallel cabinet 2 are respectively arranged on the outside of the cold air inlet 21 and the hot air outlet 22. At the same time, a sealing rubber ring is provided at the connection between the air cavity cabinet 1 and the parallel cabinet 2. The sealing rubber ring surrounds the outside of the cold air outlet 14 and the hot air inlet 15 to play a sealing role, reduce the leakage of cold air and hot air, improve the heat dissipation efficiency and reduce the impact on the environment of the other cabin or computer room.

[0037] like Figure 5 As shown, when the present invention is working, the cold air output from the air outlet of the air conditioner in the cabin or the computer room is directly and dynamically introduced into the cold air channel 12 of the air cavity cabinet 1, and flows into the parallel cabinets 2 on both sides through the electric shutters of the cold air outlet 14 on both sides of the air cavity cabinet 1, and performs heat exchange with the electronic equipment in the parallel cabinet 2 to dissipate heat and cool the electronic equipment. After the heat exchange, the temperature of the cold air increases and becomes hot air, and then the hot air in the parallel cabinets 2 on both sides is respectively vented by the fan arrays of the hot air inlet 15 on both sides of the air cavity cabinet 1. The air is sucked into the hot air duct 13 of the air cavity cabinet 1, and finally discharged to the outside of the cabin or computer room from the external exhaust port through the hot air duct 13. The entire heat exchange process is completed between the air cavity cabinet 1 and the two parallel cabinets 2. It has separate cold and hot air ducts, which are completely isolated from the environment of the cabin or computer room, reducing the impact on ambient temperature and noise. At the same time, the cold air can directly enter the two parallel cabinets 2, improving the heat dissipation efficiency, which is of great significance in the layout and environmental control of equipment in electronic cabins, computer rooms, etc.

[0038] In addition, the heat consumption of the electronic equipment in the two parallel cabinets 2 can be different. The specific indicators of the cold air intake and hot air outlet of the two parallel cabinets 2 can be calculated according to the heat dissipation requirements of the electronic equipment in the two parallel cabinets 2, so that the heat dissipation work of the two parallel cabinets 2 can be independently controlled through the control panel 17 on the side wall of the air cavity cabinet 1. Specifically, the opening angles of the two groups of electric blinds are adjusted respectively through the two angle control switches on the control panel 17, thereby changing the effective air outlet area of the cold air outlet 14 on both sides of the air cavity cabinet 1, thereby realizing independent adjustment of the cold air intake volume of the two parallel cabinets 2, and the fan speed of the two groups of fan arrays is adjusted respectively through the two speed control switches on the control panel 17, thereby changing the suction working capacity of the fan, thereby realizing independent adjustment of the hot air outlet volume of the two parallel cabinets 2.

[0039] Temperature sensors are installed in both parallel cabinets 2. The temperature sensors are in communication with the control panel 17 and send the collected temperature data to the control panel 17 for display in real time, so that the staff can understand the temperature conditions in the parallel cabinets 2 at any time.

[0040] In summary, this is only one specific combination of the present invention. In addition to the combination of the air cavity cabinet 1 and the parallel cabinet 2 described in this embodiment, it can also be a combination of an air cavity cabinet 1 and a parallel cabinet 2, such as Figure 6 As shown, at this time, only the electric shutters and fan arrays on the side of the air cavity cabinet 1 connected to the parallel cabinet 2 are adjusted, and the electric shutters and fan arrays on the other side are closed. In addition to the two combinations mentioned above, the combination of air cavity cabinets 1 and parallel cabinets 2 can also be expanded to a series connection of N air cavity cabinets 1 and N+1 parallel cabinets 2 with intervals between them, such as Figure 7 As shown, any parallel cabinet 2 connected between two air cavity cabinets 1 is provided with cold air inlet 21 and hot air outlet 22 on both side walls thereof and connected to the air cavity cabinets.

Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the scope of protection of the present invention.
