Abstract

The utility model discloses a tubular heat transfer element for the air. The heat transfer element comprises a coiled tube, two ends of the coiled tube are respectively fixedly connected with binding posts, a spiral resistance wire is arranged in the coiled tube, a gap exists between the spiral resistance wire and the inner wall of the coiled tube, magnesium oxide power is filled into the gap, and two ends of the spiral resistance wire are respectively electrically connected with the binding posts at the two ends of the coiled tube. The tubular heat transfer element is simple in structure, small in volume, high in thermal efficiency, resistant to high temperature and high voltage, uniform in heating, simple in installation, long in service life and safe and reliable in performance; and the magnesium oxide powder with good thermal conduction and insulation performance is filled into the coiled tube, so that the highest work temperature of the tubular heat transfer element can reach about 350 DEG C.

Description

Air send thermal element with tubulose
Technical field
The utility model relates to the electrical heating elements field, and specifically a kind of air send thermal element with tubulose.
Background technology
Electrical heating elements is electric energy conversion to be become the components and parts of heat energy, is widely used on the industry such as Injection Industry, chemical industry, auxiliary heating and the electrical equipment such as Household electric oven, vertical air conditioner.In chemical industry, need to come material drying by baking oven, the baking oven endogenous pyrogen comes from its inside electric heating tube is installed, effective area of dissipation is little, power consumption large, the inhomogeneous defective of generating heat but electric heating tube exists.
The utility model content
The purpose of this utility model is to provide the large air of a kind of efficiently radiates heat area and send thermal element with tubulose, is arranged in the blowing pipeline of baking oven heating system, for blow warm air in baking oven.
The technical solution of the utility model is as follows:
A kind of air send thermal element with tubulose, it is characterized in that: include coiled pipe, the two ends of described coiled pipe are fixedly connected with respectively binding post, be provided with spiral resistance wire in coiled pipe, has the space between the inwall of described spiral resistance wire and coiled pipe, and being filled with magnesia powder, the two ends of spiral resistance wire are electrically connected to the binding post at coiled pipe two ends respectively.
Described air send thermal element with tubulose, it is characterized in that: described coiled pipe is the stainless steel metal pipe.
Described air send thermal element with tubulose, it is characterized in that: described binding post is fixedly connected on the two ends of coiled pipe by securing member.
The beneficial effects of the utility model:
The utility model is simple in structure, and volume is little, high temperature high voltage resistant, and the heat efficiency is high, heating is even, simple installation, long service life, safe and reliable, the heat conductivility of inserting in coiled pipe and insulation property are good magnesia powder all, and its maximum operating temperature can reach 350 ℃ of left and right.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of air send thermal element with tubulose, include coiled pipe 1, the two ends of coiled pipe 1 are fixedly connected with binding post 2 by securing member 5 respectively, be provided with spiral resistance wire 3 in coiled pipe 1, have the space between the inwall of spiral resistance wire 3 and coiled pipe 1, and be filled with magnesia powder 4, the two ends of spiral resistance wire 3 are electrically connected to the binding post at coiled pipe 1 two ends respectively.
In the utility model, coiled pipe 1 is the stainless steel metal pipe.
During binding post 2 energising, under the water conservancy diversion of the spiral resistance wire 3 in coiled pipe 1, drainage, its heat that gives out becomes undulation reach, fully carries out heat exchange with the surface of coiled pipe 1 simultaneously, makes to dry that ducted air-flow obtains rapidly, high-efficiency heating.
