BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a control system for a heating medium oil using a sealed heating and cooling apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hermetically sealed heating and cooling apparatus, and more particularly, to a hermetic type heating and cooling apparatus which is capable of rapidly heating or quenching thermal oil used for press- And more particularly, to a heat medium oil temperature control system using the apparatus.

In general, a printed circuit board (PCB) refers to a component that is integrated with a wiring board on an insulating substrate so that various components can be mounted or an electrical connection between the components can be performed. Examples of the component include a ram, a main board, , LAN cards, and the like.

The printed circuit board is manufactured by the copper-clad laminate 1 as shown in Fig. A copper clad laminate is a basic material for producing a printed circuit board, and is referred to as a CCL (copper clad laminate) original plate.

That is, the printed circuit board is formed by cutting a CCL disc to form a working panel, and a circuit is formed on one or both sides of the working panel to arrange a plurality of PCB panels, and then the outer edges of the PCB panels are processed.

At this time, the CCL circular plate is a laminate of copper foil attached to the upper and lower portions of the free legs containing epoxy or phenolic resin in the glass fiber, and when a circuit is formed on the working panel, a plurality of unit substrates are arranged on the PCB panel .

As shown in Fig. 1, the copper-clad laminate 1 has a structure in which conductive layers 3 and 4 made of copper are laminated on both sides of an insulating member 2 made of an epoxy resin material. The wiring of the copper-clad laminate 1 (referred to as a printed circuit board) is formed by a circuit pattern formed by etching the conductive layers 3 and 4, Is referred to as a single-sided printed circuit board, and a printed circuit board on which wiring is formed on both sides of the insulating member 2 is referred to as a double-sided printed circuit board.

Although not shown in the drawing, a heating and cooling apparatus for press-molding a PCB original plate according to the prior art has an expansion tank at the top of the pipe due to the nature of the expansion tank and the system structure. Therefore, There is a drawback in that it is limited.

As a result, it is impossible to install a heating and cooling device in a low-height building and the height of a limited building can not be lowered. Therefore, the building is required to be highly constructed when a new building is constructed, or the existing building structure must be changed.

In addition, since the expansion tank is not formed in a hermetically sealed structure, when the original plate of the PCB is press-molded, there is a problem that other harmful vapor and vent may be generated due to the volume change due to expansion and contraction of the expansion tank.

Korean Patent Registration No. 10-1110706 discloses an original plate for a printed circuit board and a manufacturing method thereof.

Accordingly, the embodiments of the present invention relate to a heat medium oil temperature control system using a hermetically sealed heating and cooling device, in which a sealed expansion tank can be installed without being restricted by a building height, thereby realizing practical use.

The inlet side is communicated with the second control valve 60 and the outlet side is communicated with any position of the upstream side heating pipe 30 of the heating device 50. After being cooled by the heat exchanger 100, And a branch pipe 120 for preventing the heated heat medium oil, which is heated by the heating device 50 and then moved to the second pump 80 side, from colliding with each other can do.

A closed expansion tank 130 (reflex expansion tank) communicating with the heat exchanger 100;

The inlet side is connected to the inflow conduit 10 through the conduit L-14 or the inlet port is connected to the heating conduit 30 between the heating device 50 and the second control valve 60 through the conduit L- Or a vent tank 140 through which the inlet side communicates with the heating device 50 through a conduit L-150.

In this case, a closed expansion tank 130 for preventing a portion of the piping system having a relatively low internal pressure from being ruptured or leaking due to the control of the pressure in the piping during expansion or contraction according to the temperature change of the heat medium oil, It is noted that the vent tank 140 for maintaining the pressure in the tank at the set pressure is a technical content used in the technical field of the present invention, and thus detailed description of the construction and operation thereof is omitted.

In the drawings, reference numeral 150 denotes a heat medium oil which is heated by the heating device 50 when the heat medium oil cooled by the heat exchanger 100 is supplied to an arbitrary facility via the multi-channel heat exchanger 70 It is a check valve to prevent it from mixing with the heat medium that is moved and cooled.

Hereinafter, a heat medium oil temperature control system using a hermetically sealed heating and cooling device according to an embodiment of the present invention will be described in detail.

(A) Heating oil for use in a certain facility is heated at a high temperature (for example, about 200 to 300 캜).

2 and 3, when the heat medium oil discharged from an arbitrary facility (not shown) flows through the inlet portion (not shown) of the inflow conduit 10 (L-1), the inflow conduit 10 The heat medium oil is moved to the heating pipe 30 by the first control valve 20 provided at the outlet side.

That is, by switching the ball (not shown) of the first control valve 20, the heating channel 30 (L-2) is connected to the inlet channel 10 (L-1) The cooling line 90 (L-9) is kept closed with respect to the inflow conduit 10 (L-1).

Therefore, the heat medium oil flowing into the inlet pipe 10 (L-1) passes through the first control valve 20, and is then sucked by the suction force of the first pump 40 installed on the middle side of the heating pipe 30 And is moved to the heating device 50 via the check valve 150 and the first pump 40 in turn.

That is, the heat medium oil flowing into the inlet pipe 10 (L-1) from the arbitrary equipment is supplied to the first control valve 20 through the L-2 check valve 150 and the heating pipe 30 The first pump 40 and the L-4 constituting the heating pipe 30 are sequentially moved to the heating device 50. The L-

The heat medium oil transferred to the heating device 50 may be heated to a certain temperature by a hot source (for example, electricity, steam, or the like may be used).

Here, the technical content of the heating device 50 for heating the heating medium oil to a certain temperature by the heat source is used in the related art, and thus detailed description of the configuration thereof is omitted.

The heating fluid heated to be raised to a certain temperature by the heating device 50 is moved along the L-5 forming the heating pipe 30 and is moved to the second control valve 60.

At this time, the L-6 of the heating pipe 30 is connected to the L-5 of the heating pipe 30 by being switched to the ball (not shown) of the second control valve 60, The branch passage 120 (L-12) is kept closed with respect to the L-5 of the branch passage 120 (L-12).

The heating fluid heated by the heating device 50 is moved along the L-5 of the heating pipe 30 and moved to the second control valve 60 and then the multi-channel line 70 (L-7) 6-multi-channel line 70 (L-7) of the heating line 30 by the suction force of the second pump 80 installed in the channel between the discharge line 110 and the discharge line 110 (L-8) (L-8), and is supplied to an arbitrary facility.

As described above, the heat medium oil discharged from an arbitrary facility and requiring heating at a certain temperature is supplied to the inlet pipe 10 (L-1) - the first control valve 20 - the heating pipe 30 (L-2) The valve 150 is connected to the heating pipe 30 and the first pump 40 to the heating pipe 30 and the heating device 50 to the heating pipe 30, The second control valve 60 is connected to the heating pipe 30 through the multi-pipe 70 and the second pump 80 through the discharge pipe 110 and the pipe L-8. And may be fed to any facility after being moved in turn.

B) Cooling the thermal oil for use in any facility will be described with reference to the accompanying drawings.

2 and 4, when the heat medium oil discharged from an arbitrary facility (not shown) flows through the inlet portion (not shown) of the inflow conduit 10 (L-1), the inflow conduit 10 The heat medium oil is moved to the cooling pipe 90 by the first control valve 20 provided at the outlet side.

That is, by switching the ball (not shown) of the first control valve 20, the cooling line 90 (L-9) is connected to the inlet line 10 (L-1) The heating channel 30 (L-2) is kept closed with respect to the inflow conduit 10 (L-1).

Accordingly, the heat medium oil flowing into the inlet pipe 10 (L-1) passes through the first control valve 20, and is then transferred to the heat exchanger 100 installed in the cooling pipe 90.

Therefore, the heat medium oil flowing into the heat exchanger 100 exchanges heat with the cooling source flowing in and out along the inlet pipe (a) and the outlet pipe (b).

At this time, the technical content of the heat exchanger 100 for heating the heat medium oil discharged from the arbitrary facility by mutual heat exchange with the cooling water is used in the related art, and therefore detailed description of the structure thereof will be omitted.

The heat medium oil that has been heat-exchanged with the cooling water in the heat exchanger 100 and cooled to a certain temperature is discharged from the heat exchanger 100 and then discharged through the multi pipe line L-7 and the discharge pipe line 110 (L-8) (L-10), the multi-channel line 70 (L-7), the second pump 80, and the discharge line passage 110 (refer to FIG. 1) by the suction force of the second pump 80 installed in the channel between the cooling channel 90 L-8) are sequentially moved to be supplied to an arbitrary facility.

At this time, the second control valve 60 is changed over to the ball so that the heating channel 30 (L-6) remains closed with respect to the heating channel 30 (L-5) -5), the branch passages 120 (L-12) are kept in a communicated state.

Accordingly, the heating medium oil heated to a predetermined temperature by the heating device 50 flows through the heating pipe 30 (L-5), the second control valve 60, the branch pipe 120, the first pump 40, The process of circulation to the heating device 50 is repeated.

Accordingly, the refrigerant is cooled to a predetermined temperature by the heat exchanger 100 and then moved along the multi-channel line 70 (L-7) - the second pump 80 - the discharge line 110 (L-8) It is possible to prevent the supplied heat medium oil from mixing with the heat medium oil heated to a certain temperature by the heating device 50. [

As shown in FIG. 5, when the temperature is controlled through the heating device 50 or the heat exchanger 100, the heating oil discharged from an arbitrary facility is controlled at a predetermined temperature Heating, or cooling, and then re-supplied to any facility.

It is needless to say that the temperature control for heating or cooling the heat medium oil can be controlled automatically or manually by the control unit 160.
