The heat generated during the use of all kinds of electrical equipment is often encountered in life. High temperature will cause temperature-sensitive semiconductors, electrolytic capacitors and other components to accelerate material aging, increase internal mechanical stress and other problems, and may cause internal problems. The part catches fire, so why does the electrical equipment heat up when it is used? Electrical equipment is a kind of machinery and equipment driven by electrical energy, and when electrical energy is converted into other energy, it will be accompanied by loss. A large part of this part of energy is dissipated in the form of heat. This is also caused by the operation of electrical equipment. One of the causes of fever.
Heat-dissipating silicone sheet is a widely used material in thermally conductive filling materials. With its excellent thermal conductivity, it is accepted and applied by consumers. The heat-dissipating silicone sheet is made of silicone oil as the base material and added with a gap made of temperature-resistant and thermally conductive materials. The filled thermal pad has the characteristics of high thermal conductivity, low interface thermal resistance, insulation, compressibility, etc., because of its softer hardness, it can realize a smaller thermal resistance under low pressure conditions, and at the same time Eliminate the air between the contact surfaces and fully fill the rough surfaces between the contact surfaces to improve the heat conduction effect of the contact surfaces.
Heating of machinery and equipment is common, because when current flows through the resistor, heat is generated, and the internal heat of the device is not easy to circulate, which may easily cause local temperature rise. In order to ensure that the device can run for a long time, a heat dissipation module will be installed above the heat source. The heat is directed from the heat source to the heat dissipation module, thereby reducing the temperature.
Battery application and research is the main core of the current development of the times. It is the most widely used in the field of new energy, ranging from micro-robots to large space stations. There are battery applications. It can be said that the development of the battery industry is a sunrise industry today. Large and small batteries fill people’s lives and work, and people’s clothing, food, housing, and transportation are inseparable from their existence. While they provide power for machinery and equipment or electronic consumer products, they have many potential safety hazards, such as high temperature, fire, malfunction and malfunction. , The service life drops sharply, etc., among which high-temperature fire is the most deadly.
The core of a pure electric vehicle is its battery pack, and the battery generates a lot of heat during the driving process. If the temperature is not controlled in time, it will cause the car battery to run out of control, which will cause a chain reaction, and there are great safety risks. Therefore, battery heat is required. management. In pure electric vehicles, hybrid electric vehicles and other power systems that use batteries as the power source, battery thermal management mainly includes: air cooling, liquid cooling, thermoelectric cooling, heat pipe cooling, and phase change material thermal management. To put it simply, it is to monitor the temperature of the battery, including heating and heat dissipation, to ensure that the battery is in a suitable working environment and to ensure its performance and service life.
In order to ensure that the machinery and equipment can run for a long time, a radiator is usually installed above the power consumption components to guide the heat from the heat source to the radiator, so as to dissipate heat in time, so that the machinery and equipment can operate within a stable temperature range. There are gaps between the heat source and the radiator, and the air between the gaps will hinder the transfer of heat. Therefore, it is necessary to fill the heat transfer material between the two to remove the air at the interface, so that the heat can quickly pass through the heat transfer material to the radiator. Large machinery and equipment or some high-precision instruments require high voltages, and their internal voltages are often too high. Common heat-conducting materials are extremely easy to be ionized, so that the heat-conducting materials are broken down, and the heat-conducting materials make them work. Thermally conductive materials with breakdown voltage, such as heat dissipation insulators.
The heat of machinery and equipment is inevitable, because in reality there will be losses when electric energy is converted into other energy. A large part of this lost energy is dissipated to the outside in the form of heat. This is why heat is generated when current passes through the resistor. . The conductivity of heat in the air is low, and it is easy to accumulate inside the equipment and cannot be effectively dissipated to the outside, causing the internal temperature to rise, which affects the equipment.
Automated industrial production is the trend of the times. Most enterprises and factories have developed to a fully automated production model, which can not only improve production efficiency, but also reduce labor costs, and machine-produced products can effectively guarantee their quality, so fully automated Assembly line production is the main force of the future social production mode. Machinery and equipment can work 24/7, but there will be heat during the operation of machinery and equipment. If it is not effectively controlled, long-term high-temperature operation will cause damage to machinery and equipment. In severe cases, it may crash or even catch fire, so timely heat dissipation It is one of the keys to maintain long-term working of machinery and equipment.
What is the thermal conductive material? Many people in society may not be able to fully say what it means. Thermally conductive materials are industrial materials. Their characteristics make them suitable for various environments and requirements. They have appropriate countermeasures for possible thermal conduction problems and are highly integrated with equipment. , And ultra-small and ultra-thin provide powerful heat dissipation support. Although thermal conductive materials are industrial materials, they are closely related to the items used in our lives. Mobile phones are one of the more widely used electronic products. It can be said that every adult has at least 1-2 mobile phones, and people use them. In the process of the mobile phone, the back of the mobile phone is often found to be very hot. If it is used for a long time, it may cause the mobile phone to crash or even catch fire, so it needs to be cooled.
Energy vehicles are a hot field in today’s society. When major well-known auto manufacturers are developing their own traditional vehicles, they also begin to develop new energy vehicles. At present, the world-renowned representative of new energy automakers is Tesla. Because pure electric vehicles have a high reputation in various countries, many domestic manufacturers have begun to develop electric vehicles, so electric vehicles will become a means of transportation for people in the future.
People cannot change the heat generated during the operation of the equipment, because in reality, the energy conversion process is accompanied by loss. Most of the lost energy is dissipated in the form of heat, so it appears that people will generate heat when using the equipment. However, the internal space of machinery and equipment is small, and heat cannot be quickly transferred to the outside. This causes the internal temperature to rise and affects the performance and service life of the machinery and equipment. If it is serious, it will cause the machinery and equipment to crash or even catch fire. Therefore, temperature control is necessary.
Although it is a normal process to generate heat during the operation of electrical equipment, its internal space heat transfer efficiency is low, and the heat is easy to accumulate and cause the temperature to rise. High temperature is a factor that consumes the service life of the equipment and affects its performance. At the same time, it will cause the equipment to be serious. It crashes or even catches fire, so heat dissipation is required.
The heat generated during the operation of the equipment is a phenomenon that people often encounter in production and life. It is mainly due to the loss when the electric energy is converted into the target energy. Most of the energy lost in this part is in the form of heat. When machinery and equipment are running, heat will be dissipated. Although it is normal to generate heat, excessive temperature will affect the performance and service life of machinery and equipment, so it is necessary to control the temperature. Installing the radiator above the heat source can effectively guide the heat around the heat source to the radiator and play a role in controlling the temperature, but in fact the heat dissipation effect will not reach the expected effect, because there is a gap between the radiator and the heat source. Even if the two surfaces are smooth and flat, there is still a gap where the two are attached. The air in the gap will hinder the heat transfer, so the heat transfer to the radiator is blocked, which affects the heat dissipation effect.
Electrical equipment is frequently used in modern people’s production work. While it brings convenience to people, it also has potential safety hazards. Heat will be emitted during the operation of electrical equipment, even if it is placed in a ventilated and shaded place or an air-conditioned room. It will not solve the problem of heat generation, mainly because the conversion of electric energy into target energy will be accompanied by loss, and most of the lost energy is in the form of heat, so it will be accompanied by heat dissipation during operation.
In order to effectively control the temperature, people will install a radiator above the heat source to guide the heat to the radiator in time to ensure that the temperature of the heat source remains within a stable range. However, if the radiator is installed directly, the heat dissipation effect is not good, mainly because of the heat source There is a gap between the radiator and the radiator, even if the gap is invisible to the naked eye, there is still a gap, so the heat transfer through the gap is reduced, resulting in a decrease in heat dissipation efficiency.
