Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a tube-type heater mounting device that requires cooling in order to remove the heat accumulated inside the reflector of the heater.

[Conventional technology]

The tube-type heater is attached to a pipe that allows a low-temperature fluid to flow inside, and cools the heat stored inside the reflector to the low-temperature fluid inside the pipe by radiating heat to keep the reflector temperature below the allowable temperature. There is a need. In this mounting method, a tube-type heater is mounted on a cooling pipe consisting of a simple pipe. Note that, as a device related to this kind of device, for example, Japanese Utility Model Laid-Open No. 55-75009 can be cited.

[Problems to be solved by the device]

In the above-mentioned prior art, since the tube-type heater is simply attached to the pipe, there is a risk that the cooling pipe to which the heater is attached may be displaced in the axial mounting position and fall off at the time of attachment. However, there is a problem in that it is necessary to check the mounting position when the heater is removed for the special support structure and maintenance, and the heater is mounted again.

The present invention is intended to simplify a positioning method for mounting a tube-type heater requiring cooling on a cooling tube.

[Means for Solving the Problems]

The above-mentioned object is a cooling pipe with fins in which fins are continuously provided on the outer surface of the cooling pipe in the longitudinal direction of the pipe, and a fin notch for mounting a tube type heater is provided in the fin of the cooling pipe with fins in the longitudinal direction of the pipe. This can be achieved by providing the heater at a predetermined interval and attaching a tube heater to the fin notch portion of the finned cooling pipe.

[Action]

By mounting the tube-type heater in the fin notch portion of the finned cooling pipe, the positioning method when mounting the heater can be simplified, and it can be prevented from dropping during mounting and displacement after mounting. .

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. 1 is a tube heater, 2 is a fin 2a provided on the outer surface, and a tube heater is attached at a predetermined interval corresponding to the heater attachment position. Finned cooling pipe with fin notch 2b for
Is a cooling pipe supporting device, in which the tube heater 1 is fitted into the fin notch 2b, and the mounting member 1a is fastened with the mounting bolts 4, so that the tube heater 1 is cooled with fins at predetermined intervals. Can be attached to 2. Also, the cooling pipe with fin 2
Is fixed in place by fastening the fins 2a and the cooling pipe support device 3 with the mounting bolts 5. The reason why the cooling pipe with fins is used in the present invention is that it is easy to determine the mounting position when mounting the tube-type heater at multiple points in the longitudinal direction of the cooling pipe or when remounting the heater after removal. In addition, it is to reduce the number of installation work steps. That is, it is to simplify the positioning method at the time of mounting. In addition, since a thin circular pipe is generally used for the cooling pipe due to the heat transfer performance requirement, the method of welding the heater fixing bracket to the outside of the circular pipe is not easy to weld, and the metal of the pressure resistant portion of the pipe is not welded. It has the drawback that it has a thermal effect on the structure and that it cannot reliably inspect for welding defects. As a method for solving this drawback, a cooling pipe with fins is adopted as a cooling pipe, a notch is provided at a predetermined position of the fin, and a heater is fixed.

[Effect of device]

ADVANTAGE OF THE INVENTION According to this invention, a heater can be reliably attached to a predetermined position, and it can prevent falling off at the time of attachment,
Further, it is possible to prevent the positional deviation after attachment and to fix the cooling pipe with fins to the cooling pipe supporting device via the fins, so that the cooling pipe supporting structure can be simplified. it can.
