Background

The relay is an electric control device, is usually applied to an automatic control circuit, is an 'automatic switch' which uses a small current to control a large current to operate, and plays the roles of automatic regulation, safety protection, circuit conversion and the like in the circuit. When the relay works, as long as a certain voltage is added at the two ends of the coil, a certain current can flow in the coil, so that an electromagnetic effect is generated, and then the movable spring is pushed by the push rod until the movable spring is attracted with the static spring. When the coil is powered off and the electromagnetic attraction is small, the armature returns to the original position, and the movable spring is separated from the static spring.

When the relay is in the circular telegram use, because mutual inductance generates heat for the temperature of relay is higher, leads to the relay to damage very easily, and because the size restriction relay is inside can not set up heat dissipation mechanism mostly, so just need the heat dissipation base to come to dispel the heat to it, but current relay heat dissipation base all carries out the heat dissipation through the form of seting up the louvre basically, but the relay generally all installs in indoorly, and the air circulation nature is not very good, so the radiating effect is general.
