As a result, due to the structure in close contact with the pipe, not only the performance for keeping warm is excellent but also the assembly and disassembly with the pipe is easy, so the detachability is excellent and there is no fear that the heater heating wire itself will be disconnected even when the detachable work is reversed. The advantage is that the life is extended.

Since the heating units 110 applied in the present embodiment have the same or similar structure to each other, the same or similar reference numerals are given to the heating units 110 below.

As shown in FIG. 1, the pair of heating units 110 are connected to one body by the connection part 120.

For the purpose of explanation, the term 'heating unit' used in the specification may be used to mean a pair or one, and the 'heating block' may also be used as a pair or one. In addition, for the purpose of explanation, the term 'heating object' refers to various pipes (straight pipe, elbow pipe, bending pipe, T-shaped pipe), and valves (VCR valve, three-way valve, or valves) mounted on the pipe. Four-way valve), and / or MFC.

The connection part 120 may be any one of various structures such as a hinge, a hinge, a clip, a band, an O-ring, and the like, but is not limited thereto. . For example, a pair of heating units 110 may be connected to each other using a material such as a string instead of the connection part 120. In the case of using a string, a pair of heating units 110 may be provided with holes (not shown) facing each other, and a pair of heating units 110 may be connected to each other by passing a string through the holes. .

1 and 2, the heating unit 110 according to an embodiment of the present invention may include a heating block 130, a heat insulating material 140, and a heater 150.

Just as a pair of heating unit 110 can be provided in an assembly type, the pipe heating block 130, the heat insulating material 140 and the heater 150 can also be assembled and used in parts, that is, parts (part) In this way, it is possible to adaptively cope with various arrangement conditions, shapes and structures of the pipe. In particular, as will be described in detail below, since the pipe heating block 130 may be manufactured and used in various ways according to the type and shape of the pipe, it is possible to adaptively cope with various arrangement conditions, shapes, and structures of the pipe.

Piping that may be used in embodiments of the present invention may be industrial tubing of any size and structure. Industrial piping refers to piping used for various purposes, such as semiconductor devices or boilers, the specifications may also vary. In the case of this embodiment, the piping of a straight type (or "date") is illustrated.

Pipe heating block 130 is a portion that substantially supports while wrapping the pipe.

A pipe accommodating part 131 is formed in the central region of the pipe heating block 130 to accommodate at least a portion of the straight pipe. The pipe accommodating part 131 may have a substantially hemispherical shape, and may be processed intaglio to maintain close contact with the pipe.

On both sides of the pipe accommodating part 131, the flange part 132 is formed in a large area around the pipe accommodating part 131. The flange portion 132 serves to double the effect of thermal insulation by covering the pipe accommodated in the pipe accommodation portion 131 with a large area as if it is a blanket.

An end portion of the flange portion 132 is further provided with a stepped portion 133 which is provided to be more lifted than the other surface. The pipe heating block 130 may be manufactured by plastic working using a metal material having excellent thermal conductivity.

Pipe heating block 130 according to an embodiment of the present invention, as described above, can be manufactured (molded or processed) in a structure that can be in close contact with the shape of the piping structures to maximize the heat transfer efficiency.

Aluminum or stainless steel may be used to maximize heat transfer efficiency, but other metals such as copper, negative, or engineering plastics may also be used.

The pipe heating block 130 may be applied to a straight pipe as in the present embodiment, may be applied to pipes of other shapes as in the following embodiments, and may be manufactured by other methods other than plastic working using a press. . For example, it can manufacture by various methods, such as plastic working of presses, extrusion etc., melt working of castings, cutting processing of lathes, milling, etc.

In the present embodiment, a plastic working method using a press is selected from various processing methods. In the case of the press working method, depending on the physical properties (ductility, malleability, etc.) of the metal itself, the type of metal that can be used is limited, and the thickness applicable to each metal may be limited, but such limitations are advantageous in the embodiments of the present invention. It can work.

However, in order for the pipe heating block 130 to be applied to various types of pipes as in the present embodiment, the production should be easy and simple, and such a point should be sufficiently considered.

The reason why the stepped portion 133 is formed at the end of the pipe heating block 130 is that the pipe heating block 130 has a clearance structure of a slightly floating shape when the pipe heating block 130 overlaps with the pipe, so that the machining dimension error during the pipe production. (Including both '+' and '-' tolerances) and the total length change due to warpage of pipe geometry installed at the site depending on the situation.

The heat insulator 140 is provided on the outside of the pipe heating block 130 to insulate the pipe from the outside air.

The heat insulator 140 can be used as long as it has a material property that satisfies insulation, heat resistance, self-extinguishing property, and the like. For example, most commonly a polymer material such as silicone rubber may be used, but various kinds of engineering plastics may be used.

Although the heat insulating material 140 of the hemispherical shape is illustrated in this embodiment, the shape is only one example, and the scope of the present invention is not necessarily limited to the hemispherical shape. The shape of the heat insulating material may depend on the shape of the pipe heating block. For example, when a straight pipe heating block is used, the insulation has a shape surrounding the straight pipe heating block, and when an elbow pipe heating block is used, the heat insulating material has a shape surrounding the elbow pipe heating block. When the block is used, the insulation has a shape surrounding the bent pipe heating block, if the T-shaped pipe heating block is used the insulation will have a shape surrounding the T-shaped pipe heating block. The heater to be described later may also depend on the shape of the pipe heating block.

The connector fastening part 141 is provided outside the heat insulating material 140, and the wire fastening part 143 is provided at the connector fastening part 141.

The connector fastening part 141 and the wire fixing part 143 may be manufactured in various forms. If the external appearance of the connector fastening part 141 and the wire fixing part 143 is provided as a compact structure, it may be advantageous to avoid interference with peripheral structures. For example, as shown in the drawings, the connector fastening portion 141 may have a substantially block structure, and the wire fixing portion 143 may be provided as a hole in the form of a long hole, but their shapes and structures may vary.

The heater 150 is a substantial heating means provided between the pipe heating block 130 and the heat insulator 140, and the heat from the heater 150 is transmitted to the pipe heating block 130, so that the pipe can be kept warm. .

Heater 150 according to an embodiment of the present invention may be a heater having a planar heating structure, for example, Kapton heater (Kapton Heater), silicon rubber heater (Silicone Rubber Heater), or mica heater (Mica Heater) This can be applied. It is a matter of course that the present invention is not limited to such heaters.

According to an embodiment of the present invention, the heater 150 having a planar heating structure is typically formed with a heat generating pattern by a chemical etching method using a thin metal plate of the same material (Nichrome ㄾ, STS, etc.).

The temperature sensor 151 may be variously applied such as a thermocouple, an RTD, a thermostat, and the like.

On the other hand, when using the Kapton heater according to an embodiment of the present invention, it can exhibit various advantages when using the temperature sensor 151. For example, even if the temperature sensor 151 is attached on the insulating polymer surface, its thermal response characteristics are excellent, so that the temperature sensor 151 can be used without any deterioration in performance, and thus the convenience of not having to directly attach the temperature sensor to the heating object can be exerted. have.

On the other hand, the controller 160 controls the operation of the heater 150 of the industrial pipe heating apparatus according to the present embodiment. As shown in FIG. 3, the controller 160 includes a central processing unit 161 (CPU), a memory 162 (MEMORY), and a support circuit 163 (SUPPORT CIRCUIT). The CPU 161 may be one of various computer processors that can be industrially applied to control the industrial piping heating apparatus of the present embodiment. The memory 162 is connected to the CPU 161 in operation. The memory 162 may be a computer-readable recording medium and may be located locally or remotely and may be any of various types of storage devices, including, for example, a random access memory (RAM), a ROM, a floppy disk, At least one or more memories. The support circuit 163, SUPPORT CIRCUIT, is operatively coupled with the CPU 161 to support typical operation of the processor. Such a support circuit 163 may include a cache, a power supply, a clock circuit, an input / output circuit, a subsystem, and the like.

For example, the process according to the on / off operation of the heater 150 in the industrial pipe heating apparatus according to the present embodiment may be stored in the memory 162. Typically, a software routine may be stored in the memory 162. The software routine may also be stored or executed by another CPU (not shown), which may be located remotely from the industrial piping heating apparatus.

Although processes according to the present invention are described as being performed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

With this configuration, as shown in FIG. 1, the pair of heating units 110 are opened with the connecting portion 120 as an axis, and the pipes are positioned therebetween to arrange the pipes in the pipe receiving portion 131 of the heating unit 110. After the connection, the other heating unit 110 is pinched in the direction of the arrow with the connecting portion 120 as the axis.

Then, by fastening the detachable coupling portion 125 it is possible to easily install the industrial pipe heating apparatus of the present embodiment.

After the assembly is completed, when the operation of the heater 150 is turned on, heat from the heater 150 is transmitted to the pipe through the pipe heating block 130, thereby maintaining the pipe's warmth.

As described above, according to the present embodiment, not only the work for keeping the pipes warm and easy to recycle is also possible, and in particular, it is possible to adaptively cope with various arrangement conditions, shapes, and structures of the pipes.
