Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning energy conservation and emission reduction, in particular to a radar electronic equipment integrated cabinet and a control system thereof. Background Art

[0002] Electronic equipment such as transceivers and power supplies are important components of the radar system. The radar electronic equipment cabinet is the main carrier of radar electronic equipment. The cabinet's heat dissipation capacity directly affects whether the radar system can work properly.

[0003] Existing radar electronic equipment cabinets are primarily categorized as cradle-type and pull-out types. These cabinets often house two rows of multi-layered, high-power radar electronic equipment, generating significant heat. Currently, commonly used cooling methods include air cooling and liquid cooling. Liquid cooling offers high heat dissipation efficiency, but it also comes with complex structural design, high initial investment costs, high safety requirements, and the risk of leakage. Therefore, air cooling has become the preferred cooling method for radar electronic equipment cabinets.

[0004] However, existing air cooling is usually in the following forms: (1) computer room air conditioning, which has no air duct layout and lacks the ability to accurately control the temperature of specific areas inside the cabinet. This can easily cause uneven heat dissipation of equipment components far away from the air conditioner, resulting in high temperature alarms on the equipment and the inability of the radar to operate normally; (2) placing the fan on the top of the cabinet and on the cradle, and the cabinet is sealed, forming an internal closed heat dissipation flow channel inside the cabinet. This method has limited heat dissipation capacity and high power consumption, making it difficult to meet the ever-increasing heat dissipation and energy-saving needs.

[0005] In addition, all the plug-in cables of the radar electronic equipment cabinet are arranged centrally at the rear of the cabinet. Especially for the plug-in radar electronic equipment cabinet, when the cables are maintained and disassembled, the electronic equipment must be pulled out of the cabinet from the front before subsequent operations can be performed. Therefore, the cooling and heat dissipation structure of the radar electronic equipment cabinet must also take into account the function of facilitating maintenance.

[0006] It can be seen that there is an urgent need for an intelligent, efficient and convenient cooling and air supply solution to solve the heat dissipation problem of radar electronic equipment cabinets. Utility Model Content

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A radar electronic equipment integrated cabinet includes a housing, an air conditioner, an air supply duct, and a door. The air conditioner and the air supply duct are integrated into the housing, the air conditioner is connected to the air supply duct, and multiple layers of radar electronic equipment are installed in the housing from top to bottom in a height direction.

[0011] The main pipeline and the connecting pipeline are of a split structure. When the door body is closed, the main pipeline can be connected to the connecting pipeline. When the door body is opened, the main pipeline can be disconnected from the connecting pipeline.

[0012] Furthermore, the multiple layers of radar electronic equipment are divided into two rows and arranged in the casing, and the connecting pipes include a first connecting pipe and a second connecting pipe. One end of the first connecting pipe is provided with an air inlet end, and the other end forms two branch pipes. The end of each branch pipe is provided with an air outlet end, the air inlet end is connected to the air conditioner, and the two air outlet ends are respectively connected to one second connecting pipe, and the two second connecting pipes are respectively connected to one main pipe.

[0013] Furthermore, each of the main pipes and each of the second connecting pipes is provided with a connecting flange at the connection between the two, and a sealing structure is provided on the connecting flange.

[0014] Furthermore, the first connecting pipe is provided with a plurality of air balancing plates at the air outlet end.

[0015] Furthermore, a slanted pressure regulating plate is provided in the main pipeline.

[0016] Furthermore, the door body is a mesh door or a grid door with through holes.

[0017] The present utility model also relates to a control system for an integrated cabinet of radar electronic equipment, the control system comprising an air conditioner control module and a temperature sensor, the temperature sensor being used to sample the temperature value at the air outlet of the radar electronic equipment and report the sampled temperature value to the air conditioner control module, the air conditioner control module controlling the start or stop of the air conditioner according to the temperature value and a set temperature value.

DETAILED DESCRIPTION

[0035] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below 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 creative work are within the scope of protection of the present invention.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] Example 1

[0038] A radar electronic equipment integrated cabinet, see Figures 1-4 The air conditioner 3 is located at the bottom of the housing 1 and below the radar electronic equipment 2. The air conditioner 3 is located below the radar electronic equipment 2. The air conditioner 3 includes a main duct 41 and a connecting duct. The air conditioner 3 is connected to the main duct 41 via the connecting duct. The main duct 41 is provided with a plurality of air outlets 411. Each radar electronic equipment 2 is provided with an air inlet 21 on the side near the air supply duct 4. Each air outlet 411 corresponds to the air inlet 21 of the radar electronic equipment 2. The cold air blown out by the air outlet 411 can be directly supplied to the radar electronic equipment 2 through the air inlet 21.

[0039] An air outlet 411 is provided on the air supply duct 4 at a position corresponding to the air inlet 21 of the radar electronic device 2 to ensure that cold air can be blown evenly and directly toward the radar electronic device 2, thereby reducing unnecessary heat transfer and loss and improving cooling efficiency.

[0040] The connecting pipe is fixedly connected to the air cooler 3. The main pipe 41 and the connecting pipe are of a separate structure. The main pipe 41 is fixedly mounted on the inner surface of the door 5, which is located on the front of the housing 1. The main pipe 41 can be connected to or disconnected from the connecting pipe as the door 5 is closed or opened. Specifically, when the radar electronic equipment integrated cabinet is in normal operation, the door 5 remains closed, and the main pipe 41 can be connected to the connecting pipe. At this time, the cold air generated by the air cooler 3 can be transported to the radar electronic equipment 2 through the main pipe 41, quickly cooling the electronic equipment. When the equipment malfunctions and the door needs to be opened for maintenance or replacement of the radar electronic equipment 2, the door 5 is usually opened. At this time, the main pipe 41 is disconnected from the connecting pipe and moves with the door 5 to a hidden position, ensuring that the radar electronic equipment 2 is exposed for easy maintenance or replacement. This design is more suitable for plug-in radar electronic equipment cabinets. When the radar electronic equipment 2 is pulled out of the cabinet, it will not be interfered with by the main pipe. The door 5 can be opened manually or automatically.

[0041] In this embodiment, the radar electronic equipment 2 is divided into two rows and arranged in the housing 1. In order to achieve uniform supply of cold air, ensure uniform heat dissipation of the radar electronic equipment and improve cooling efficiency, see Figure 5-Figure 6The connecting pipe includes a first connecting pipe 42 and a second connecting pipe 43. One end of the first connecting pipe 42 is provided with an air inlet end 421, and the other end forms two branch pipes. The end of each branch pipe is provided with an air outlet end 422. The air inlet end 421 is connected to the air conditioner 3, and the two air outlet ends 422 are respectively connected to one second connecting pipe 43. The two second connecting pipes 43 are respectively connected to one main pipe 41, which is used to evenly supply cold air to the two rows of radar electronic equipment 2.

[0042] The first connecting pipe 42 and the second connecting pipe 43 can be an integrated structure or a split structure. The split structure can reduce manufacturing costs and facilitate installation or removal of the pipes.

[0043] like Figure 6 As shown, each of the main pipes 41 and each of the second connecting pipes 43 is provided with a connecting flange 44 at the connection between the two. A sealing structure is provided on the connecting flange 44. The connecting flange 44 and the sealing structure can increase the contact area of ​​the joint and ensure good sealing, avoid cold air leakage, and ensure the smoothness and reliability of the connection.

[0044] like Figure 5 As shown, a number of air balancing plates 423 are provided at the air outlet end 422 of the first connecting pipe 42, which can effectively evenly distribute and guide the airflow entering the connecting pipe, thereby preventing the airflow from forming vortices or dead corners therein, reducing energy loss, and improving the overall ventilation efficiency; at the same time, the setting of the air balancing plates 423 also has a certain noise reduction effect, which can reduce the noise generated when the airflow passes through the first connecting pipe 42 to a certain extent, thereby improving the user experience.

[0045] like Figure 7-Figure 8 As shown, the main pipe 41 has an inclined pressure regulating plate 413, and the pressure regulating plate 413 and the inner wall of the main pipe 41 form a gas circulation pipe 412. The cross-sectional area of ​​the gas circulation pipe 412 gradually decreases along the gas flow direction, which can balance the wind speed and wind pressure at various locations in the pipe, thereby ensuring that the wind pressure and wind speed of each air outlet 411 are basically consistent, significantly improving the uniformity of airflow distribution.

[0046] In addition, the door body 5 is a mesh door, a lattice door, etc. with through holes, and the cold air in the machine room can enter the cabinet through the through holes of the door body 5 to cool the radar electronic equipment 2. In this embodiment, the cooling mode can be switched according to the temperature conditions in the cabinet. Specifically, when the heat dissipation demand of the radar electronic equipment 2 is high, such as in a high temperature environment in summer or when the temperature in the cabinet is high, the door body 5 is ensured to be in a closed state, and the air conditioner 3 is controlled to work. At this time, the main pipe 41 is connected to the connecting pipe, and the cold air generated by the air conditioner 3 is transported to the air inlet 21 of the radar electronic equipment 2 through the main pipe 41, thereby realizing targeted cold air supply and effectively reducing the temperature of the radar electronic equipment 2. At this time, the cold air in the computer room can simultaneously enter the radar electronic equipment 2 through the door body 5, and the two form a superimposed effect, greatly improving the cooling efficiency. When the heat dissipation demand of the radar electronic equipment 2 is low, such as in winter or when the temperature in the cabinet is low, the door body 5 can be in either an open state or a closed state. At this time, the air conditioner 3 is controlled to stop working. Under the suction action of the fan inside the electronic equipment, only the cold air in the computer room passes through the door body 5 and the air inlet 21 into the radar electronic equipment 2, thereby achieving cooling of the electronic equipment. By intelligently switching between the two cooling modes, the temperature inside the radar electronic equipment 2 is always kept at a low level without the need for the air conditioner to continuously supply cold air throughout the day / year, thereby achieving efficient use and effective conservation of energy while ensuring heat dissipation effects.

[0047] The main pipe 41 is further provided with an air outlet pipe 45. Figure 7-Figure 8 The air outlet 411 is arranged at the end of the air outlet duct 45. This arrangement can effectively guide the flow of cold air in the main duct 41, so that the cold air can flow more concentratedly to the air inlet 21 of the radar electronic equipment 2, thereby achieving higher cooling efficiency.

[0048] The main pipe 41 is detachably connected to the door body 5. The door body 5 is not limited to the traditional door opening method of rotating along the door axis, but can also be a sliding door or other various forms of openable and closable door mechanisms. The connection between the door body 5 and the main pipe 41 can be connected by means of buckles, screws, etc., so that when the door body 5 needs to be repaired or replaced, or when the main pipe 41 fails, it can be quickly and conveniently disassembled and assembled, thereby greatly improving the efficiency and convenience of maintenance.

[0049] Example 2

[0050] This embodiment relates to a control system for the above radar electronic equipment integrated cabinet, including an air conditioner control module and a temperature sensor. The radar electronic equipment 2 also includes an air outlet 22. Figure 4The air outlet 22 is arranged on the opposite side of the air inlet 21 of the radar electronic device 2, and a plurality of temperature sensors are arranged near the air outlet 22. The temperature sensors are used to sample the temperature value at the air outlet 21 and report the sampled temperature value to the air conditioner control module. The air conditioner control module can control the start or stop of the air conditioner 3 according to the temperature value and the set temperature value.

[0051] The temperature sensor reports the detected temperature value to the air conditioner control module, and the air conditioner control module realizes efficient switching of the air conditioner working state according to the relationship between the temperature value and the set temperature value set by the control system.

[0052] Specifically, (1) if the temperature value is less than the set temperature value, the air conditioner control module controls the air conditioner 3 to shut down for 3 minutes, and then continues to perform the temperature detection step; (2) if it is detected that the temperature value is greater than the set temperature value, the air conditioner control module controls the air conditioner 3 to start and continue to provide cooling for a certain time, for example, 6 minutes; then, the temperature sensor continues to detect the temperature value at the air outlet 21. If the temperature value is lower than the set temperature value, the air conditioner control module controls the air conditioner 3 to shut down. If the temperature value is still higher than the set temperature value, the air conditioner control module controls the air conditioner 3 to continue to provide cooling for a certain time, and the above steps are executed in a cycle.

[0053] The control system further includes a door status detection module, which is used to detect the open or closed state of the door 5. The air conditioner control module can also control the start or stop of the air conditioner 3 according to the open or closed state of the door 5. Specifically, during the operation of the air conditioner, when the door 5 is opened, the door status detection module detects that the door 5 is in the open state, and then the door status detection module uploads the door status information to the air conditioner control module, and the air conditioner control module controls the air conditioner 3 to be synchronously shut down; when the door 5 is closed, the door status detection module detects that the door 5 changes from the open state to the closed state, and then the door status detection module uploads the door status information to the air conditioner control module, and the air conditioner control module controls the air conditioner 3 to be synchronously started.

[0054] Specifically, the radar electronic equipment integrated cabinet includes a high-precision door switch sensor and an air conditioner controller. The door switch sensor can be of any type, including a magnetic field sensor, a photoelectric sensor, a piezoelectric sensor, an ultrasonic sensor, and the like. The door switch sensor is signal-connected to the air conditioner controller. When a user opens door 5, the door switch sensor immediately detects that door 5 is open and reports this to the air conditioner controller. Upon receiving this signal, the air conditioner controller sends a shutdown command to air conditioner 3, causing it to stop operating. When a user closes door 5, the door switch sensor immediately detects the change in state from open to closed and sends a signal to the air conditioner controller. Upon receiving this signal, the air conditioner controller sends a start command to air conditioner 3, causing it to automatically start and continue executing the original command.

[0055] The control system disclosed in this embodiment is provided with an air conditioner control module and a door status detection module, realizing the linkage between the door and the air conditioner, and can respond to the switch status of the door 5 in real time, realize the intelligent control of the cabinet heat dissipation system, avoid the waste of cold air when the door is accidentally opened or repaired, and can also automatically control the air conditioner to start after the inspection is completed, timely and effectively dissipate heat for the cabinet, reduce the user's operating burden, and improve the user experience.

[0056] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein.
