Difference between temperature transmitter cooling rod and heat sink

We understand what a temperature transmitter is (a temperature transmitter is an instrument that converts temperature variables into a standardized output signal that can be transmitted. It is mainly used for the measurement and control of temperature parameters in industrial processes) and we understand the temperature transmitter Cooling method?

The speed of heat dissipation has a great impact on the temperature transmitter. Generally, there are two types of cooling methods we choose: cooling rods and fins.

So what's the difference between a heat sink and a heat sink?

When the range is below 300 ° C and the dimensions are the same, the heat dissipation effect of the heat sink is better than that of the heat sink. The contact area between the heat sink and the air is much larger than the heat sink, so the heat dissipation effect is better.

When the measuring range is greater than 300 ℃, especially when the temperature is 500 ℃ or higher, and there is no requirement for the shape length, the heat dissipation effect of the heat sink is better than the heat sink, because the number of metal processing of the heat sink is limited, not more than 10, and the processing cost is high And, the higher the temperature, the worse the heat dissipation effect, and the cooling rod is simple and convenient to process, the cost is low, there are no too many restrictions on the length, as small as several tens of millimeters, as large as several tens of centimeters.
