Causes of easy heating of industrial tablet computers
Anyone who has used a tablet computer knows that the computer will become very hot after a period of use. The heat dissipation problem has always been a big problem since the birth of the industrial tablet computer, because the industrial tablet computer is basically a fanless design, and the heat dissipation is usually It is conducted to the body through heat transfer and other methods. Therefore, the heat dissipation of the industrial tablet computer is related to the service life and stability of the machine. What makes the industrial tablet computer easy to heat? Let's take a look together next.
Under normal circumstances, the temperature of the motherboard is about 40℃-60℃, which depends on different motherboard brands and chipsets. The chip is the part that generates a lot of heat, but the temperature is much lower than that of the CPU and the graphics card. Generally, it will not exceed 50°C; if the motherboard temperature has exceeded 60°C, please check whether the motherboard heat sink is loose. Normally the CPU temperature is 45℃-65℃ or lower. If it is higher than 75℃-80℃, check the CPU The front baffle, the baffle plate opens the mold to install the I/O interface and the power switch, etc. The black part is aluminum alloy profile, and the fin-type design is mainly for heat dissipation to increase the heat dissipation area. In terms of heat dissipation, our fanless industrial computer uses aluminum profiles. The design of this aluminum profile is to increase the heat dissipation area and stabilize the operating performance of the industrial computer. According to the editor’s question to our structural engineers, we learned that our industrial computer is applied to this type of aluminum profile. First, the aluminum alloy is in the state of half melting point, through the modeling frame, and the half melting point of the aluminum alloy is poured and extruded. The formed concave-convex strip shell.
When we are making fins, our structural engineers have taken into account the assembly of our products. When assembling, the back of the heat sink fins of the industrial computer are machined with holes and slots, which is convenient for us to assemble the front and rear baffle and the installation of the motherboard. The heat dissipation of the industrial computer of the fanless industrial computer relies on the design of large-area aluminum fins, and the heat is transferred to the fins through the heat dissipation block of the CPU, which can achieve efficient heat dissipation.
Normally, it is 50°C-70°C (or lower). When running large 3D games or playing high-definition video, the temperature can reach about 100°C. Generally, it is considered normal that the temperature does not exceed 110°C under high load. If the temperature exceeds 70 degrees, especially when the high temperature occurs at the start of the machine, you must check whether the heat sink is normal. In addition, the dust left by long-term use is also an important cause of high temperature. If the temperature of the graphics card exceeds 90 degrees, please shut down and check immediately to prevent the high temperature from burning the graphics card core or video memory and other components.
Fanless industrial tablet PCs are integrated CPUs. Generally, CPUs are big heat generators. However, many people have always believed that CPUs are the most heat-generating part of industrial tablet PCs. In fact, the heat emitted by the CPU only accounts for 7% of the overall internal heat generation. about. The reason why the processor's heat dissipation method is emphasized is that it is a concentrated heat dissipation product and is a high-frequency multi-core processor that is currently widely used. If the heat dissipation of the CPU is improperly handled, it may cause the CPU to burn out, so we focus on the heat dissipation performance of the industrial panel computer.
