Description

Technical Field

[0001] The utility model relates to the field of meteorological monitoring, in particular to a ventilation and cooling device for a cloud measuring radar fuselage. Background Art

[0002] Cloud radar is an active remote sensing device specially designed to detect cloud structure, microphysical properties and vertical distribution. Its core function is to achieve high-precision and high-resolution observation of clouds by transmitting microwave or millimeter wave signals and receiving backscattered echoes from cloud particles (water droplets, ice crystals, etc.). Cloud radar usually integrates electronic components such as transmitters, receivers, signal processing modules, and power supplies in a sealed antenna cover and main frame structure. These devices generate a lot of heat during operation. In order to avoid overheating of the equipment and accumulation of moisture that affects the normal operation of the radar host, ventilation devices (fans or duct systems) are usually required. The heat dissipation and moisture-proofing of electronic equipment ensure that the system can operate stably in a closed radome. Since the radome needs to be sealed to prevent water, dust, and salt spray, the setting of fans and ventilation paths requires reserved holes to be opened on the circular mounting plate of the main frame. It is necessary to meet the needs of ventilation and heat dissipation while considering the wiring requirements, so that the overall structure seeks a balance between sealing and ventilation. A sealing ring is usually set between the radome and the mounting plate to prevent rain, snow, wind and sand from entering. However, the sealing ring is prone to aging in high temperature environments. If it is not replaced in time, it will directly affect the sealing of the radome and affect the normal operation of the electronic components inside the radome. Therefore, a radar fuselage ventilation and cooling device is needed that does not affect the sealing of the radome while also achieving a good ventilation and cooling effect. Utility Model Content

[0003] In order to overcome the shortcomings of the above-mentioned existing technologies that are unable to achieve good cooling of the cloud measuring radar antenna cover without affecting its sealing, the utility model provides a cloud measuring radar fuselage ventilation and cooling device, including a cooling shell, the cooling shell is a barrel-shaped double-layer structure, a cavity is formed between the double layers of the cooling shell, an air guide device is fixed in the cavity, and a narrow air guide channel outlet is formed between adjacent air guide devices.

[0004] Preferably, the cooling shell is composed of two half shells with the same structure, and the half shells include an outer shell and an inner shell. The outer shell and the inner shell are coaxially arranged and form a cavity communicating with each other from top to bottom.

[0005] Preferably, both end surfaces of the half shell are provided with connecting plates, and threaded holes are spaced apart from top to bottom on the connecting plates.

[0006] Preferably, the air guide device is located at the top of the cavity of the cooling shell, the top of the air guide device is provided with a bilaterally symmetrical inclined surface, and the bottom is an inverted triangle.

[0007] Preferably, the height of the air guide device exceeds 1 / 2 of the height of the cooling shell.

[0008] Preferably, the inner diameter of the cooling shell is 1 to 5 centimeters larger than the inner diameter of the cloud measuring radar main box.

[0009] Preferably, heat-reflecting heat-insulating paint is sprayed on the outer wall of the cooling shell.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The barrel-shaped structure of the cooling shell of this device is convenient for it to be put on the outside of the cloud detection radar host, preventing direct sunlight from shining on the host and causing temperature rise, and also preventing rain from entering the cloud detection radar host and affecting the normal operation of its internal electrical components;

[0012] The cavity structure of the cooling shell creates a narrow air flow channel around the cloud radar host, creating a chimney effect. The hot air around the cloud radar host is discharged from the cavity at the top of the cooling shell, and the cold air is drawn in from the cavity at the bottom of the cooling shell, thus forming a continuous air flow that does not require external mechanical power. The naturally circulating air will cool the cloud radar host.

[0013] A number of narrow air outlet channels are formed between the air guide devices in the cooling shell cavity, so that the air flow in the cooling shell cavity is divided into several air branches, reducing the buoyancy and pressure gradient force generated by the density difference between cold and hot air, so that the cold and hot air can be quickly mixed, further accelerating the rapid passage of cold and hot air through the cooling shell cavity, and further improving the cooling effect.

[0018] The following will be combined with the drawings in the specification of the embodiment of the present invention to clearly and completely describe the technical solutions in the embodiment of the present invention. Obviously, the embodiment described is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] See also Figure 1 - Figure 3 The utility model provides a ventilation and cooling device for a cloud measuring radar fuselage, including a cooling shell 1. The cooling shell 1 is a barrel-shaped double-layer structure. A cavity is formed between the double layers of the cooling shell 1. An air guide device 4 is fixed in the cavity. A narrow air outlet channel 402 is formed between adjacent air guide devices 4.

[0020] It should be noted that the barrel-shaped structure of the cooling shell 1 makes it convenient to put it on the outside of the cloud measuring radar host to prevent direct sunlight from shining on the host and causing the temperature to rise, and also to prevent rain from entering the cloud measuring radar host and affecting the normal operation of its internal electrical components; and the cavity structure of the cooling shell 1 is used to form a narrow air flow channel (chimney effect) around the cloud measuring radar host, and cold air continuously enters the cavity at the bottom of the cooling shell 1 and is then discharged from the top of the cavity, thereby forming a continuous air flow, and the hot air generated around the cloud measuring radar host will be continuously inhaled from the bottom of the cooling shell 1 cavity with the air flow, and then discharged from the top of the cooling shell 1 cavity. Since the density of hot air is lower than that of cold air, the hot air is more easily lifted upward by the cold air, which accelerates its The air flow formed by the device from bottom to top in the cavity of the cooling shell 1 does not require external mechanical power, and can quickly remove the hot air generated by the cloud measuring radar host, thereby having a good cooling effect on the cloud measuring radar host; and a plurality of narrow air outlet channels 402 are formed between the air guide devices 4 in the cavity of the cooling shell 1, so that the air flow in the cavity of the cooling shell 1 is divided into a plurality of air branches, reducing the buoyancy and pressure gradient force generated by the density difference between the cold and hot air, so that the cold and hot air can be quickly mixed, further accelerating the rapid passage of the cold and hot air through the cavity of the cooling shell 1, and further improving the cooling effect; without the need for additional power and without affecting the overall sealing of the cloud measuring radar antenna cover, the device can have a good ventilation and cooling effect on the cloud measuring radar fuselage.

[0021] See attached Figures 1 to 2As shown, the cooling shell 1 is composed of two half shells 2 with the same structure. The outer wall of the cooling shell 1 is sprayed with heat-reflecting heat-insulating paint. The half shell 2 includes an outer shell 201 and an inner shell 202. Both end faces of the half shell 2 are provided with connecting plates 3. Threaded holes 5 are spaced apart from top to bottom on the connecting plates 3. The outer shell 201 and the inner shell 202 are coaxially arranged and form a cavity connected up and down. An air guide device 4 is fixed on the top of the cavity; the two half shells 2 are bolted and connected through the threaded holes 5 on the connecting plates 3 at their two end faces. The detachable connection method is conducive to the processing and maintenance of the cooling shell 1. The outer wall of the cooling shell 1 is sprayed with heat-reflecting heat-insulating paint to solve the problem of temperature rise caused by direct sunlight and prevent the cooling shell 1 from heating up due to sunlight and affecting the electrical components inside the cloud measuring radar host.

[0022] See attached Figure 3 As shown, the top of the air guide device 4 is provided with a bilaterally symmetrical inclined surface 401, and the bottom is an inverted triangle. The inclined surface 401 and the inverted triangle bottom are arranged so as to convert the temperature difference, pressure difference and density difference between the cold and hot air into a controllable airflow in an orderly and rapid manner, thereby accelerating the air flow and air velocity in the cavity of the cooling shell 1 and improving the cooling effect on the cloud detection radar fuselage.

[0023] See attached Figure 1 As shown, in order to ensure the effect of the air guide device 4 in the cavity, the height of the air guide device 4 exceeds 1 / 2 of the height of the cooling shell 1.

[0024] Furthermore, the inner diameter of the cooling shell 1 is 1 to 5 centimeters larger than the inner diameter of the cloud measuring radar main box, which makes it easy to sleeve the cooling shell 1 on the outside of the cloud measuring radar main box.
