This article will explain in detail how to solve the heating problem of the power chip in big data. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

When the chip is working, if it is overheated and hot, it depends on whether it is abnormal or normal.

Some power chips are indeed very hot when they are close to full load, which should be solved by increasing the heat dissipation copper skin and adding a heat sink; if some non-power chips are badly hot, they should consider whether they are caused by abnormal circuits. 1 to solve the heat dissipation problem by increasing the heat dissipation copper skin. For some power chips and power chips, greater heat will be generated when they flow through a larger current, this is normal, and the chip needs to be treated by heat dissipation. If it is a patch chip, it generally has a large area pin, which plays a good role in heat dissipation. When designing the circuit, it is necessary to make the copper skin connected to the pad larger. Let the heat generated by the chip dissipate as soon as possible, so as not to affect the performance of the chip. Now I would like to share with you the heat dissipation design of the power chip. The LM2596 shown in the figure below is a typical example.

two。 Solve the problem of heat dissipation by adding heat sink

For inline chips, such as TO-220 packaging, a fixed hole will be left on the chip to facilitate users to add heat sink according to the estimated heat when in use. In order to better heat dissipation, when installing the heat sink, the chip and the heat sink should be coated with heat dissipation silicone grease, which is conducive to heat conduction.

The figure below is a typical example of adding a heatsink.

The above two cases, are power chips, power chips, are normal heating conditions. Sometimes because of the abnormal heating caused by circuit design and welding problems, it is necessary to find and solve the problem. 3 the heat caused by the abnormal use of the chip in the event of abnormal heating of the integrated circuit, the power should be cut off immediately, first check whether the power supply is normal, whether the voltage meets the requirements, and whether the power supply is reversed; once again, check whether the power pin of the chip is short-circuited, whether the power pin is reconnected, and finally check whether there is a problem with the parameters of the components of the circuit or the chip selection.

Power chips are widely used in power electronics, power supply, automation and other industries, and the chip is very sensitive to temperature. The greater the current, the more serious the heat of the chip. Only by doing a good job of heat dissipation of the chip, can the chip work stably and normally. This is how to solve the heating problem of the power chip in big data. I hope the above content can be helpful to you and learn more knowledge.
