System that the device of body, especially pipe and this electric heater unit are constituted reaches.Favourable improvement scheme of the invention is each
The theme of a dependent claims.
Electric heater unit according to the present invention is used for Heating body, and the main body has outer diameter D and cross section Q, and excellent
Selection of land has determined pipe.Electric heater unit has shell, and the shell is especially preferably made of metal.In the inner space of shell
In be so disposed at least one electrical heating elements so that the electrical heating elements are electrically insulated with shell.
It is important to the present invention that electric heater unit has at least one section being adapted to the outer diameter of main body, the portion
The curvature of section so adapts to the outer diameter of main body, so that electric heater unit can so be placed into main body or (especially from vertical
Directly in the direction of the direction of extension of main body, the direction is previously given by the central axis of pipe in the case of a tube) main body can be shifted onto
On, so that there are plane contacts between a part of outer diameter and the adaptation section of electric heater unit, and electrical heating elements have
There is corresponding curvature.
Electrical heating elements especially have corresponding curvature when it is with such section, these sections are substantially in locking portion
It is stretched on the circumferencial direction of section and therefore on the circumferencial direction of main body and with the outer surface approximately constant distance away from main body,
The bent section of electrical heating elements is fitted on the outer surface of main body.Therefore in particular, also have ignored by main body herein
Curvature difference caused by the interval of actually very little between outer radius and electrical heating elements.
It is proved particularly advantageously, electric heater unit has U-shaped cross-section, and the U-shaped cross-section has arcuate segments
With two legs, wherein the outer profile of U-shaped cross-section is previously given by the section of shell, wherein the inside radius r of arcuate segments
It is the one medium-sized of the outer diameter D of main body, electric heater unit is applied to the heating of main body, thus by providing the cloth in main body to be heated
In the case where having set electric heater unit, the half of the cross section of main body is accommodated in arcuate segments or is more specifically accommodated in it
In interior arch, and leg substantially extends in the tangential direction towards the outer profile of main body.
Therefore, shell is understood that or is described as the profile material tube with U-tube inner space, even if it can be with its other party
Formula is formed as U-shaped especially by forming rectangular tube or oval pipe.Therefore, shell has U-shaped Internal periphery, U-shaped foreign steamer
Exterior feature, the U-shaped Internal periphery and the U-shaped outer profile are connected to each other with connect segment respectively on leg.
Therefore, the arcuate segments of shell can be interpreted as annulus section, which, which is especially covered in polar coordinates, describes
180 ° of angular range, wherein the inside radius of the annulus section adapts to the outer diameter of main body to be heated.With annulus section adjoining
It then substantially tangentially stretches in main body to be heated and generally parallel to each other leg, wherein " substantially " it is meant that inclined lower than 5 °

According to the requirement of each self-application it can be beneficial that at least two electrical heating elements independent of each other are horizontal from U-shaped
It arranges and/or is partly overlapped with offseting one from another on the Internal periphery in section to the direction of the outer profile of U-shaped cross-section.Therefore, this
A little electrical heating elements are at least stacked in the housing to section in this arrangement.
But the advantages of also can have is, at least two electrical heating elements independent of each other are arranged in U-shaped cross-section not
With in section, that is to say, that adjacent to each other in the housing or different in polar coordinates diagram even with respect to main center's axis
Indicate ground configuration in different polar angle regions.These electrical heating elements especially can symmetrically be implemented；But especially when making
With electrical heating elements with different electric operation conditions, such as operate the various operation voltages of electrical heating elements independent of each other
It also can be reasonably, to place the various sizes of section with independent electrical heating elements and therefore provide different numbers when work
The structure space of amount.
One especially to available heating power with positive influence according to the present invention is advantageously improved scheme and mentions
Out, at least one electrical heating elements is partially positioned in the leg in arcuate segments and being partially positioned in U-shaped cross-section
