BGA heat sink

In more extreme lighting situations, some type of  active cooling  may be required. This may be due to high heat flux from nearby leds, small size or surface area that is unable to  conduct natural convection , or extremely high ambient temperature conditions. Any of these conditions may change the thermal budget of certain areas and require  active cooling systems . Various "standard methods" for  active electronic cooling  have been proposed or are also used for leds, although some special conditions apply to active   LED cooling . To date, the  led cooling system  has used or recommended the use of simple dc rotating fans, thermoelectric coolers (TEC), piezoelectric fans (PZF), synthetic jets (SJ) and   liquid cooling   (such as microchannels). Each of these has specific advantages, but there are also some disadvantages to the cooling lighting system. Active cooling of lighting has special requirements that are not required for every semiconductor application. For exa

Power battery is used in new energy vehicles to provide power for the battery, power battery for the general battery for higher technical requirements, higher requirements on the sustainability of the battery, the current domestic power battery manufacturers everywhere, appeared on the surface of comprehensive development, a good scene.Power battery pack liquid cooling heatsink experts believe that the power battery pack industry will be from everywhere to the polarization of the situation into a period of time, power battery enterprise polarization is significant, bibcock with bibcock pattern is basically determined. Throughout the development of power batteries in China, the battery capacity is expanding rapidly, which leads to the continuous oversupply of lithium batteries in China.From the perspective of quality, there is a lot of low-quality production capacity, but there is still a lack of high-quality production capacity. The concentration degree of power battery industry wil

There are a lot of electrical and electronic devices that need heat sink in life, the heat sink shell required by specific products in all walks of life is different in size, material, specification and shape, etc. So the choose and buy the cooling were often are looking for  heat sink manufacturer , put forward concrete production requirements to customized processing. Business scope Lori has 15 years history, the main production and processing all kinds of aluminum automotive amplifier heat sink,  aluminum heat sinks and aluminum LED lamp heat sink , heat pipe heat sink, skived heat sink, bonded fin heat sink, liquid cold plate and engaged in processing all kinds of aluminum products, hardware and electronic accessories, heat sink special terminal products, such as the production of the products are widely used in automotive, lighting, electronics, construction and other industries. The strength of the company Since the establishment of  this heat  sink manufacture

Do you know the harm caused by IGBT module overheating?   IGBT module itself has a certain power, the module itself will generate heat, the overall performance and reliability of IGBT module are affected by temperature.   Design rules are often used to compare failure rate figures.According to the design guidelines, one of the design rules shows that the failure rate will double for every 10 ℃ rise in temperature when the component is operating in an environment above 65 ℃ .So cooling IGBT module is also extremely important work! IGBT module is high power semiconductor devices, loss power makes the heat more, combined with the IGBT junction temperature should not exceed 125 ℃, should not be long   term work at higher temperatures, usually large current through the IGBT module, switching frequency is higher, leads to the wastage of the IGBT device is big also, if the heat is not spread out in time, make the device junction temperature over 125 ℃, IGBT module should not be long-term w

Collection mode heat pipe and zipper fins at present there are mainly two kinds, respectively is welding (Solder) and wear a Fin (Fin Penetration), welding process of the interface zipper resistance is low, but the cost is higher, such as aluminum fins and copper heat pipe welding, basic need to electroplating processing of heat pipe, can with aluminum fins welded together, and welding is high also to craft requirement, welding uneven or internal bubble, heat transfer efficiency will be significantly impaired. Fin piercing is to let heat pipe directly through the Fin by mechanical means. This process is simple, but the technical requirements are no lower than that of welding, because it requires the heat Fin to have close contact with the heat pipe. If Fin piercing fails, not only the zipper efficiency will be greatly reduced, but the  zipper Fin  may even fall off directly.At the same time, in order to ensure that Fin array does not deform, Fin piercing process is often used in con

S kiving heat   sinks  are involved in many fields (such as large servers, computers, frequency converters, automobiles, refrigerators, large machines, medical, communications, radio and television equipment, military industry, etc.). S kiving fin technology originated from abroad, mainly used in aerospace, military, precision machine tools, electronic equipment and other sophisticated or high-precision industries.With the progress of science and technology and processing technology, S kiving fin  technology   has been gradually transferred to civilian use and applied to IT and  industrial heat sink   manufacturing industry.The principle is a whole piece of copper or aluminum according to needs, with a professional skived fin  machine cut out the standard spacing of heat sink fin, because of the use of precise skived fin  technology, integrated manufacturing, heat transfer medium stability, heat sink thickness is greatly reduced, under the same conditions the heat t ransfer   effect i
