Steam Heaters Have High Heat Transfer Coefficient
May 31, 2017


The steam heater includes an upper cover, a heater main body and a lower cover, the heater main body includes a frame body and a heater substrate fixedly connected at one end of the frame body, Steam (heat Exchanger) Electric Heater and the one end of the frame body and the heater substrate is die-molded with a U-shaped electric heating pipe The upper cover and the lower cover are fixedly fastened on both sides of the heater main body and exposed to the temperature measurement contact part to form an upper steam channel and a lower steam channel, the upper steam channel and the lower layer A steam outlet is provided between the steam passages and a steam outlet corresponding to the upper and lower steam passages. Steam (heat Exchanger) Electric Heater The position of the heater substrate near the steam outlet is provided with a staggered arrangement The cylinder, the steam outlet has a passivation layer. This structure of the steam heater, heat fast, high heat utilization, adaptability, suitable for flip operations, while avoiding the steam outlet blockage, reducing manufacturing costs.

Steam heater as a heating device, now in a number of areas have been a lot of applications. Because it is different from the air heater, Steam (heat Exchanger) Electric Heater so today we need to come to a good study in order to know what kind of heater should be used where the analysis is described below.

Steam heater is made of steel and aluminum composite finned tube as a heat exchanger, so it combines the steel pipe pressure and aluminum high thermal conductivity, excellent heat transfer performance, Steam (heat Exchanger) Electric Heater and has a certain degree of corrosion resistance, and its compact structure, Easy to clean.

Steam heater specific features are:

(1) The heat transfer element uses the spiral fins, and the fins are integrally pressed once, so the connection with the base pipe is good, the contact resistance is small, and the heat transfer coefficient is high.

(2) It maintains a constant low resistance value over a wide range of temperatures and has good resistance to temperature and vibration.

(3) finned tube is wrong layout, so the heat transfer area, heat transfer coefficient is also high.

(4) pipe design distribution is very reasonable, Steam (heat Exchanger) Electric Heater and the air flow is very uniform.

(5) steam heater in the factory has been hydrostatic test to ensure that no leakage phenomenon.

Steam heater installation is also an important part, can not be ignored, the specific are:

(1) steam heater should be used before the inspection, mainly to see whether the collision or injury, if damaged, should be repaired, and the need for re-testing and testing.

(2) should be carried out according to the provisions of lifting and installation, lifting lifting to be smooth, to prevent distortion of the components deformation, or hit the fins.

(3) After the steam heater is installed, clean up the debris, Steam (heat Exchanger) Electric Heater including all the places, to prevent clogging the fins, affecting the normal operation.

(4) steam heater is not used, the internal water should be drained clean, so as not to freeze the tube in winter, affecting the use.
