surface load and surface temperature

Relationship between surface load and surface temperature of electric heat pipe placed in metal

Heating tube placed in metal heating is also a very common working state, such as: casting heater is the casting heating tube;

The mold hole is heated, and the heating tube is inserted into the hole. The smaller the hole clearance is, the better;

, etc.

So today I'm also going to tell you about the surface temperature of the tube when it's heated in metal.

If the heating tube is cast in metal to heat.

The heating tube is cast in brass to form a copper casting heating block. The surface load of the heating block should be selected from 0.1-5w/cm2. We obtain the relation curve between the surface temperature of the heating plate and the surface load of the tube by test method.

In the test, when the surface temperature of the heating block reaches 500℃, the heat state inside the heating tube placed in the metal is the same as that in the air.

From the data given in the graph, you can see the electrical power of the heating block when it reaches the required temperature.
