For example, the fire detection unit 100 may be installed in an engine room of an aircraft, an automobile, a train, a ship, or the like, and may be installed in a form of winding around an engine. The fire detection unit 100 is designed by applying a Seebeck effect, which is one of the thermoelectric properties of a material, and a thermoelectromotive force due to a potential difference when a part of a sensing line receives heat in a specific temperature range. To detect fire. The detailed configuration of the fire detection unit 100 will be described later.

The control unit 200 recognizes the fine thermal power generated by the fire detection unit 100, amplifies it, calculates it after the operation, and determines whether a fire has occurred. to be. To this end, the controller 200 includes various electronic circuits, and a program for calculating a potential difference generated by the fire detection unit 100 and determining whether a fire has occurred may be built in. The detailed configuration of the control unit 200 will be described later.

2 is a perspective view of a fire detection unit according to a preferred embodiment of the present invention, Figure 3 is a left side view of Figure 2, Figure 4 is a right side view of FIG. 5 is a cross-sectional view of FIG. 2.

2 to 5, the fire detection unit 100 according to the preferred embodiment of the present invention includes a sensing line assembly 110, a sensing line plug assembly 120, and a sensing line socket assembly 150. Is formed.

The sensing line assembly 110 is formed to include the first conductor line 112, the second conductor line 114, the mineral oxide insulator 116, and the shell 118.

The first conductor wire 112 may be formed of any one of chrommel, iron, copper, and nicrosil, but is not limited thereto. The material, length, size, and resistance of the first conductor wire 112 are not limited to a specific value. Therefore, the first conductor wire 112 may be formed in various lengths and sizes according to the scale of the target to detect the fire.

The second conductor line 114 may be formed of any one of alumel, constantan, and nisil, but is not limited thereto. The second conductor line 114 is spaced apart from the first conductor line 112 at regular intervals and disposed in parallel to each other, and is surrounded by the mineral oxide insulator 116 and insulated from the first conductor line 112. The second conductor wire 114 is also not limited in material, length, size, and resistance, and preferably has the same length as the first conductor wire 112.

In one example, the first conductor wire-second conductor wire may be combined such as chromel-alumel, chromel-constantan, iron-constantan, copper-constantan, nicrosil-nisyl. Specifically, the first conductor wire-second conductor wire has a temperature sensing range of approximately -270 to 1370 degrees Celsius when it is a chromel-alumel combination. In addition, the chromel-constantan combination has a range of approximately -270 to 1000 degrees Celsius, and the iron-constantan combination is approximately -270 to 400 degrees Celsius (Type T) and -210 to 1200 degrees Celsius (Type J).

The chromel-alumel combination can be used even at high temperatures and has a relatively good corrosion resistance but is somewhat vulnerable to carbon dioxide and sulfurous acid gas. The iron-constantan combination is the best in the limited temperature range for Type T and is suitable for active gases and vacuum conditions. Type J is suitable for atmospheric oxidation and vacuum, and has strong characteristics against hydrogen and carbon monoxide. In addition, the Cromel-Constantan combination can be used in low oxygen and high temperature vacuums. It is desirable to produce the mineral oxide insulator by selecting the optimal combination that satisfies the required properties.

The mineral oxide insulator 116 stabilizes the thermoelectric power generated by the first conductor wire 112 and the second conductor wire 114, so that the numerical value of the thermoelectric power at a specific temperature can exhibit a constant value. For this purpose, the mineral oxide insulator 116 is preferably manufactured by mixing a specific oxide in a specific component range.

Mineral oxide insulator 116 includes MnO, NiO, CrO components.

At this time, the mineral oxide insulator can be manufactured with a component ratio of MnO 98%, NiO 1.2%, CrO 0.8%, in this case has an optimum detection performance in the temperature range of 220 ~ 250 degrees.

In addition, the mineral oxide insulator 116 may further include CuO and SiO ₂ components. Preferably, the mineral oxide insulator 116 is manufactured with the following components and compounding ratios.

ingredient % By weight MnO 94.2-99.18 NiO 0.65 ~ 4.8 CrO 0.15-0.95 CuO 0.01 ~ 0.1 SiO ₂ 0.01 ~ 0.1

As a result of the test, when the mineral oxide insulator was manufactured with the above component blending ratio, the resistance value was fixed below a specific value, indicating that the thermoelectric power was stabilized.

Envelope 118 wraps around mineral oxide insulator 116 to protect sensing line assembly 110. As the outer shell 118, stainless steel is suitable, and the outer diameter may be manufactured in various standards such as 0.5 mm, 1.0 mm, 1.6 mm, 2.3 mm, 3.2 mm, 4.8 mm, 6.4 mm, 8.0 mm, 12.7 mm. Here, the specification of the outer shell 118 is not limited.

When the first conductor wire 112 is aluminel, the resistance between the aluminel and the shell is about 10 kΩ or more, when the second conductor wire 114 is cromel, the resistance between the cromel and the sheath is about 10 kΩ or more, and the aluminel and cromel It is also preferable that the resistance between the two is about 10 kΩ or more. As described above, in order to stabilize the resistance value between the aluminel and the outer shell, the cromel and the outer shell, the aluminel and the cromel, it is necessary to adjust the component ratio of the mineral oxide insulator. In addition, it is preferable that the resistance of the aluminum wire itself is 4 m / 75 Ω or less, and the resistance of the chrome wire itself is 4 m / 175 Ω or less.

Originally, the Seebeck effect means that in a circuit composed of two different types of metal conductors, if there is a temperature difference at the junction of the two metals, a potential difference occurs at both ends.

When a metal has a temperature gradient, the electrons at the hot end of the metal rod have a higher kinetic energy than the electrons in the cold zone. Thus, the electrons have a thermal driving force that tries to flow from the hot zone to the cold zone in order to reduce their average kinetic energy. As the electrons diffuse toward the cold region, a Seebeck voltage is generated in the metal rod, which tries to send the electrons back to the hot end of the rod. Equilibrium is obtained when the Seebeck potential is exactly balanced with the thermal drive force for the electron flow.

However, according to such a structure, since heat is generated when heat is applied to the joint portions of two different metals, there is a problem that only a fire of a specific location and area can be detected.

According to the present invention, the thermoelectric power is generated for a specific range of temperature depending on the type of the first conductor wire, the second conductor wire, and the mineral oxide insulator, regardless of the length and size of the sensing wire and regardless of the part and region to which heat is applied. Let's go.

In addition, since there is no physical or chemical change in the detection line even after the fire detection, it can be used semi-permanently unless the detection line is damaged by external force. In addition, the reaction speed is fast and accurate because the fire is detected by recognizing the potential potential difference by calculating the voltages of the chromel and aluminel lines generated by chemical reaction of the internal mineral oxide element in proportion to the temperature change. In addition, it is possible to set the desired temperature range according to the blending ratio of the mineral oxide component.
