China's navy released the first international standard electronic chart

[China Ship Network ( CnshipNet China)] Recently, the Navy officially launched the international standard version of the China Sea Electronic Chart at the National Convention Center. This is the first time that China has officially released the electronic chart of the international standard of China Sea Area.

In addition to ensuring the navigation of ships, electronic charts are also widely used in marine engineering construction, fisheries, marine exploration and other fields. At present, electronic charts used by some domestic ships are non-standard electronic charts, even pirated charts, because the information is not Standard and content are not standardized, and there are hidden dangers to the safety of the ship. As the official sea channel measurement agency and the only official official maritime book publishing institution in China, the Navy is obliged to provide Chinese official electronic charts to users all over the world.

Li Pengcheng, the director of the Naval Command of the Naval Command, introduced the basic situation of the official electronic chart of China. The electronic chart adopts an international update mode, and an update file is released every week. The user only needs to import the update file into the "electronic chart display and information system" to update the electronic chart data. As long as the electronic chart is loaded in the "electronic chart display and information system", the system can automatically display the position of the ship acquired by the GPS positioning device on the map, effectively overcoming the information caused by the manual drawing of the paper chart. Hysteresis, superimposed with the radar image, can fully grasp the sea area around the ship, and also has the functions of planned route plotting, actual track record, navigation hazard alarm, etc., as long as the navigation notice is received remotely by satellite or radio. The automatic updating of the chart greatly increases the safety and convenience of the ship's navigation.

According to the regulations of the International Maritime Organization, starting from July 1, 2012, new passenger ships of 500 gross tonnage and above and tankers of 3000 gross tonnage and above shall be equipped with an electronic chart display and information system. With the mandatory installation of the system on ships built in different tonnages, different types and at different times, and the superiority of electronic charts, ship navigation will rely more on electronic charts.

Lieutenant General Du Jingchen, Deputy Chief of Staff of the Navy, Major General Leng Zhenqing, Ministry of Foreign Affairs, General Administration of Press and Publication, National Bureau of Surveying and Mapping, National Oceanic Administration, China Geological Survey, Maritime Safety Administration, Ministry of Agriculture, Fisheries Bureau, Fishing Department The inspection bureau, the Military Commission Legal Affairs Bureau, the General Surveying and Mapping Bureau, the General Political Propaganda Department and other representatives of the relevant military departments attended the launching event.

Aluminum Heat Sink

Aluminum Heat Sink is a type of heat exchanger that is used to dissipate heat from electronic devices. It is made of high-quality aluminum alloy, which has excellent thermal conductivity and is lightweight, making it ideal for use in electronic devices.The aluminum heat sink is designed to increase the surface area of the electronic device, allowing for more efficient heat dissipation. It works by transferring heat from the device to the fins of the heat sink, which are then cooled by the surrounding air.Aluminum Heat Sink is widely used in various electronic devices such as computers, LED lights, power supplies, and audio amplifiers. It is available in different shapes, sizes, and designs to suit different applications.The heat sink is easy to install and maintain, making it a popular choice among electronic manufacturers. It is also durable and long-lasting, ensuring that electronic devices perform optimally for an extended period.
Overall, Aluminum Heat Sink is an essential component in electronic devices, ensuring that they operate efficiently and reliably.What is a heat sink?Heat sinks help dissipate heat from heat sources to ambient air by using increased surface area to maximize heat transfer. Heat sinks come in a variety of constructions, but all include collecting heat into a base, conducting heat to the fins, and using the added surface to dissipate heat. Heat sinks are devices that enhance heat dissipation from a hot surface, usually the case of a heat generating component, to a cooler ambient, usually air. For the following discussions, air is assumed to be the cooling fluid. In most situations, heat transfer across the interface between the solid surface and the coolant air is the lead efficient within the system, and the solid-air interface represents the greatest barrier for heat dissipation. A heat sink lowers this barrier mainly by increasing the surface area that is in direct contact with the coolant. This allows more heat to be dissipated and/or lowers the device operating temperature. The primary purpose of a heat sink is to maintain the device temperature below the maximum allowable temperature specified by the device manufacturer. Remgar Metal company produces a wide variety of Standard Extruded Heat Sink options for quick solutions optimized for board level devices like TO packages, BGA/FPGA devices, and even CPUs & GPUs. These standard heat sinks are available with different mounting methods and some come with pre-applied thermal interface materials to streamline assembly into your PCB.
