The order of internal structure of many substances changes under certain circumstances. For example, iron can be ordered in a magnetic field environment to form N-poles and S-poles. Thermal magnetic materials can also be arranged in a thermal field environment to form heat. Extreme and cold. First, the working principle of the thermomagnetic radiator When the current passes through the wire, a spiral magnetic field is formed around the wire; likewise, when the heat flows through the strip-shaped thermomagnetic material, a spiral heat field is formed around the strip-shaped thermo-magnetic material, under the action of the spiral thermal field. The formation of hot gas flow, we call it the hot field gas flow. The hot field airflow forms an active exchange with the cold air to achieve the purpose of heat dissipation. Therefore, the thermomagnetic heat sink belongs to the dynamic heat dissipation category. Second, the characteristics of thermal magnetic radiator Compared with traditional heat sink: LED heat sink application of thermal magnetic heat dissipation material / magnetic cooling heat sink material, can achieve LED100W light source heat sink weight less than 2 kg, reduce metal weight 5-10 times, temperature rise less than 20 degrees, make LED become true temperature Low, long life, low cost, and affordable new light source. The material synthesis is simple: a small amount of thermal magneton additive is added to the heat-dissipating material such as copper or aluminum to form a thermo-magnetic heat-dissipating material. Since the specific component of the additive is close to pure aluminum and the melting point is lower than 400 ° C, the synthesis of the material is very simple. Dynamic heat dissipation: The thermal magnetic radiator is a dynamic heat dissipation type and has a very strong exchange capacity with cold air. The heat dissipation effect is much better than the ordinary copper and aluminum radiators. Strip-shaped heat dissipation: After adding the thermo-optical material to the heat sink, the surface of the heat sink will form a hot-field airflow that moves laterally with the direction of heat propagation. If we design many strips on the heat sink that are parallel to the direction of heat propagation, A strip of spiral heat field flow around the strip is created, which increases the heat exchange area and capacity of the hot and cold air. Therefore, we recommend that the thermomagnetic heat sink be designed in the shape of a strip. Phonon characteristics: Most of the thermomagnetic materials have phonon characteristics at the same time, which will generate sinusoidal oscillations under thermal motion, thus generating thermal radiation. In the thermal magnetic radiator, the thermal radiation of the phonon features also increases the heat dissipation effect of the heat sink. Surface treatment: The surface treatment of the thermomagnetic radiator can also be done by baking or electrostatic spray. The thermal magnetic radiator is cooled by a spiral heat field airflow. Just as baking paint and electrostatic spray do not affect the magnetic field, baking paint and electrostatic spray will not affect the generation and flow of the heat field. Instead, the paint can be used. And the high electrostatic emission rate of the electrostatic spray to improve the heat dissipation effect. For example, when the exposed thermomagnet heat sink temperature is 45 ° C, the surface temperature of the heat sink can be reduced to 41 ° C after surface treatment with baking paint and electrostatic spray. * Light efficiency and power stability: Since the temperature of the chip will experience a low-to-high process after each ignition of the LED, the luminous efficiency of the LED chip decreases as the temperature of the chip increases, and the operating voltage of the LED chip also follows the temperature of the chip. Increase and decrease (power reduction). Therefore, the light efficiency and power of the LED after each ignition are lowered as the temperature increases. The temperature rise of ordinary aluminum radiators is very high, the light efficiency and power of LEDs are much lower, and the temperature rise of thermomagnetic radiators is very low, so the light efficiency and power are relatively stable. LED light decays and has a long life: the temperature rise of the thermomagnetic radiator is generally controlled at 5-15 ° C, which is 25-30 ° C lower than that of ordinary aluminum radiators. Therefore, the light decay of the LED is very small, which greatly prolongs the service life of the LED light source. Light weight, low consumables, low carbon emissions for manufacturing: Thermomagnetic heat sinks are very lightweight, have very few consumables, and require only 8-15 grams of heat sink per W power consumption, which is equivalent to ordinary aluminum. The 1/5-1/10 of the radiator greatly reduces the carbon footprint of the material manufacturing process. The wind resistance is very small: the streetlight with a thermomagnetic radiator has a very small wind resistance. The side wall area of ​​the 200W VII radiator is only 0.035m2, and the windward surface is a 30 degree vertebra, which is spread over the strip hole. The wind resistance is less than 1/5~1/10 of the traditional street lamps, which is very suitable for areas with frequent coastal typhoons. High production efficiency: The thermal magnetic radiator is stamped and manufactured by adding hot magnetic material. The production efficiency is very high, and the production efficiency is ten times higher than that of the heat sink manufacturing process such as die casting and extrusion. Low cost: The material cost of the thermomagnetic radiator is slightly lower than that of ordinary aluminum, and at the same time it has the characteristics of light weight, low consumables and high processing efficiency. Therefore, the total cost of the radiator is much lower than that of the ordinary aluminum radiator. . The plate type heat sink with the heat transfer layer combined with the heat dissipation layer and the heat sink directly fixes the LED on the plate heat sink by the SMD method, and opens the LED package first, completely solving the world-class problem of LED heat generation, high cost and difficulty in installation. World lighting will officially enter the era of LED lighting.
