Summary of the invention
The utility model is intended to the technological deficiency for prior art, provides a kind of combined efficient anti-explosion electric heater, thus solves the technical problem that in prior art, anti-explosion electric heater pyroconductivity is poor.
Another technical problem that the utility model solves is the frame for movement simplifying anti-explosion electric heater on the basis ensureing the efficiency of heating surface.
For realizing above technical purpose, the utility model by the following technical solutions:
A kind of combined efficient anti-explosion electric heater, comprise mount pad, described mount pad is provided with electric heating tube, and described electric heating tube is provided with some baffle plates, and what be parallel to each other between adjacent described baffle plate is staggered, described baffle plate is semi-circular, described baffle plate is provided with some through holes, is provided with filter screen in described through hole, and described electric heating tube material is nickel Lip river alloy, the radius of described semi-ring is 20 ~ 30mm, has spiral helicine streak line at described electric heating tube outer wall.
Preferably, the thickness of described baffle plate is 2 ~ 3mm.
Preferably, described through-hole wall has rifling.
Preferably, described filter screen is 40 mesh sieves.
Preferably, the radius of described semi-ring is 23mm.
Because described electric heating tube is provided with some baffle plates, what be parallel to each other between adjacent described baffle plate is staggered, and fluid fully can be contacted with electrical heating group, improve heat conduction efficiency, in addition, described baffle plate is provided with some through holes, is provided with filter screen in described through hole, can improve the flow velocity of fluid, and avoid the impurity in fluid to flow out, the effect of filtration can be played, thus, use convenient.In addition, arranging striped at electric heating tube outer wall can lifting heat transfer efficiency, can not increase the complexity of structure simultaneously.The utility model achieves outstanding technique effect with relatively simple technological improvement, and cost is lower simultaneously, is easy to realize, and therefore has outstanding promotion prospect.
