我们知道,电视机工作时机内温度较高,特别是大幕彩电更是如此。机内的热量主要来自电源电路、行输出电路、场输出电路和显像管管颈,其中电源电路发出的热量最多。过高的机内温度不仅增加了元器件的故障几率,而且增加了功耗,浪费了电能。现代新型大屏幕彩电的设计已经考虑到这一问题,并采取了改进措施,收到了较好的效果。本文就电源电路的降温减耗措施给大家做一介绍。 We know that the TV set has a higher temperature in the working hours, especially the big screen TV. Machine heat mainly from the power circuit, the line output circuit, field output circuit and tube neck, of which the power circuit emits the most heat. Excessive temperature inside the machine not only increases the probability of failure of components, but also increases the power consumption, wasted power. The design of the modern new large-screen TV has taken this issue into consideration and taken improvement measures and received good results. This article on the power circuit cooling measures for everyone to make an introduction.
