Description

유해 전자파방지 전열선Hazardous Electromagnetic Wave Heaters

본 고안은 전기장판, 요, 카페트 등에 적용되어 열원을 제공하는 전열선(ELECTRIC HEATING WIRE)에 관한 것으로, 특히 열선과 온도감지선이 일체로 된 기존의 전열선에 유해전자파를 감쇠되도록 한 수단을 부설시키므로서 열선으로 부터 방출되는 열잡음성 유해전자파를 중화되도록 함과 동시에, 외부접지로 방출할수 있도록 한 유해전자파 방지 전열선에 관한 것이다.The present invention relates to a heating wire (ELECTRIC HEATING WIRE) that is applied to electric blankets, urine, carpets, etc. to provide a heat source, and in particular, by laying a means for attenuating harmful electromagnetic waves to existing heating wires in which the heating wire and the temperature sensing wire are integrated. The present invention relates to a noxious electromagnetic wave prevention heating wire which is capable of neutralizing the thermally noisy noxious electromagnetic waves emitted from the thermal wires, and at the same time, it can be emitted to an external ground.

종래의 전기장판, 요, 카페트 등에 적용되는 전열선은 도 1로 도시된 바와 같이 열선(1)을 적어도 복수가닥의 절연사(2a-2c)로 꼬운다음 그 둘레에 온도감지센서(3)를 일정간격으로 권선하고, 다시 권선된 온도감지선(3)의 외둘레에 일정두께 절연피(4)를 피복하여 구성된 것이다.As a heating wire applied to a conventional electric plate, yaw, carpet, etc., as shown in FIG. 1, the heating wire 1 is twisted with at least a plurality of strands of insulated yarns 2a-2c, and then the temperature sensor 3 is fixed around the heating wire 1. Winding at intervals, it is configured to coat a constant thickness insulating skin (4) on the outer circumference of the temperature sensing line (3) again wound.

이와같은 종래의 전열선은 열선(1) 양 끝단에 입력전원을 연결하고, 온도감지선(3)의 양 끝단은 도시 생략된 전자제어회로에 연결한 후, 전원을 공급하면 열선(1)으로 부터는 전기에너지를 열에너지로 변환하여 열원을 제공하게 되고, 그 열원은 온도감지선(3)에 의해 감지되어 도시 생략된 전자제어회로에 전기신호로서 전달된다.Such a conventional heating wire is connected to the input power at both ends of the heating wire (1), and both ends of the temperature sensing wire (3) is connected to the electronic control circuit (not shown), and then supplying power from the heating wire (1) The electrical energy is converted into thermal energy to provide a heat source, which is sensed by the temperature sensing line 3 and transmitted as an electric signal to an electronic control circuit (not shown).

이와같은 동작은 전자제어회로내에 설정된 온도이하에서 반복적으로 동작하게 되는데, 즉 설정온도 이하에서는 상기와 같이 전원이 열선에 공급되어 발열동작하고, 설정온도에 도달하면 열선(1)에 공급하던 전원을 차단하도록 동작한다.This operation is repeatedly operated below the temperature set in the electronic control circuit, that is, below the set temperature, the power is supplied to the heating wire as described above to generate heat, and when the set temperature is reached, the power supplied to the heating wire 1 is supplied. It works to block.

그러나, 이와같은 종래의 전열선은 상기한 바와같이 열선 둘레에 온도감지선이 권착되어 전자제어회로의 제어에 의해 항상 일정한 온도를 제공할 수가 있는 장점은 있으나, 통상 열선은 전기에너지를 열에너지로 변환하는 금속성 발열 도체이므로 온도가 상승할수록 열에 의한 전자나 이온이 불규칙한 전자적인 교란작용에 의해 열잡음성 전자기파가 발생된다.However, such a conventional heating wire has a merit that a temperature sensing wire is wound around the heating wire as described above to provide a constant temperature at all times by the control of the electronic control circuit. However, the heating wire converts electrical energy into thermal energy. As it is a metallic heating conductor, thermal noise electromagnetic waves are generated due to irregular electronic disturbances caused by heat and electrons or ions due to heat.

이러한 전자기파는 인체에 도움이 되는 원적외선도 포함되어 있지만, 인체에 지극히 유해한 전자파도 포함된 상태로서 전자기복사의 이론과 파동의 성질에 의해 다른 영역의 공간으로 전파되는 성질을 갖고 있으므로서 장시간 사용자에게는 이 유해전자파로 부터 치명적인 영향을 주게되는 결점이 있다.These electromagnetic waves contain far infrared rays that are helpful to the human body, but they also contain extremely harmful electromagnetic waves, which propagate to other areas due to the theory and the nature of electromagnetic radiation. There is a flaw that has a lethal effect from harmful electromagnetic waves.

이와 같은 결점, 즉 상기한 전열선을 적용한 전기요(모포)의 열선으로 부터 유해전자파를 해소하기 위한 방안으로 본인이 선출원한 실용신안등록번호 제108921호가 있다.There is a utility model registration No. 108921 filed by the applicant himself in order to solve the harmful electromagnetic waves from the above-mentioned shortcomings, that is, the heating wire of the electric wire (foam) to which the heating wire is applied.

즉, 이 고안은 도 2로 도시된 바와같이 열선(1)의 외둘레에 온도감지선(3)과, 이 온도감지선(3)의 외둘레에 피복된 절연피(4)가 구성되고, 재차 절연피(4)로 코일형태의 에나멜선(10)을 권선한후, 절연피(20)로 피복구성하여 열선(1)에서 발생되는 열잡음성 전자기파를 코일형태의 에나멜선(10)에 유기되도록하여 전원단의 접지극을 통해 외부로 방출하도록 한 것이다.That is, this design consists of a temperature sensing line 3 on the outer circumference of the heating wire 1, and the insulating skin 4 coated on the outer circumference of the temperature sensing line 3, as shown in FIG. After winding the enameled wire 10 in the form of a coil again with an insulating sheath 4, it is coated with an insulating sheath 20 to induce thermal noise electromagnetic waves generated in the heating wire 1 to the coiled enameled wire 10. It is to be discharged to the outside through the ground electrode of the power terminal.

그러나, 상기한 고안은 열선으로 부터 발생되는 유해전자파에 대한 문제는 어느정도 해소할수 있는 효과는 있었으나, 에나멜선이 코일형태를 취하며 단선으로 구성됨에 따라 그 자계의 세기가 상대적으로 미약해지게되고, 이에 유해전자파의 감쇠영역이 한정되어지므로 효율성이 저하되는 문제점은 그대로 상존시키는 것이었으며, 특히 유동성을 갖는 전열선이 사용중 꺾임되거나 외부충격을 받으므로서 단선으로 이루어진 에나멜선이 쉽게 파손, 절단되는 등 내구성 저하로 인한 제품손실의 문제점 또한 상당한 것이었다However, the above-described design has an effect that can solve the problem of harmful electromagnetic waves generated from the hot wire to some extent, but the strength of the magnetic field becomes relatively weak as the enamel wire takes the form of a coil and is composed of single wire. Since the attenuation area of harmful electromagnetic waves is limited, the problem of decreasing efficiency remains as it is.In particular, durability is degraded, such that the enameled wire made of a single wire is easily broken and cut off due to the bending or external impact of the fluidized heating wire. The problem of product loss due to

따라서, 본 고안은 종래 유해 전자파 방지 전열선의 제반적인 문제점을 해결하고자 창안된 것으로;Therefore, the present invention was devised to solve the general problems of the conventional harmful electromagnetic wave protection heating wire;

본 고안의 목적은 열선에서 발생되는 열잡음성 전자기파를 넓은영역 범위내에서 중화, 감쇠되도록하여 효율성을 향상시키고, 이에 인체에 해로운 유해전자파의 발생을 원초적으로 억제되도록하며, 특히 내구성을 갖는 구조로서 외부영향에 의한 에나멜선의 파손으로 부터 제품이 손실되는 등의 문제점을 해결되도록 한 유해 전자파 방지 전열선을 제공함에 있다.The purpose of the present invention is to improve the efficiency by neutralizing and attenuating the thermal noise electromagnetic waves generated in the hot wire within a wide range, thereby preventing the generation of harmful electromagnetic waves harmful to the human body, and in particular as a durable structure It is to provide a harmful electromagnetic wave prevention heating wire to solve the problems such as product loss from breakage of the enameled wire by the influence.

이상, 상기 목적을 달성하기 위한 본 고안의 구체적인 수단으로는;As described above, specific means of the present invention for achieving the above object;

열선을 적어도 복수가닥의 절연사로 꼬운다음 그 둘레에 온도감지선을 일정간격으로 권선하고, 다시 권선된 온도감지선의 외둘레에 일정두께의 절연피를 피복한 전열선에 있어서,In the heating wire twisting the heating wire with at least a plurality of strands of insulating thread, and then wound the temperature sensing wire around a predetermined interval, and coated a certain thickness of insulating skin on the outer circumference of the wound temperature sensing wire,

상기 절연피의 외둘레 열선의 길이방향으로 다수가닥의 에나멜선을 망상체로 엮어 연속 꼬임되게 권선한후, 2차로 절연피를 피복하며, 또 다르게는 절연피의 외둘레, 즉 열선의 길이방향으로 도체성 박막지인 알루미늄띠를 밀착되게 권회한후, 2차 절연피로 피복하므로서 달성된다.After winding multiple strands of enameled wire in the longitudinal direction of the outer circumferential heating wire of the insulated skin and twisting the wire in a continuous twisting manner, the insulating skin is covered secondly, and the outer circumference of the insulated skin, that is, the conductor in the longitudinal direction of the hot wire This is achieved by winding the aluminum strip, which is a thin film, in close contact, and then covering it with secondary insulating skin.

이하, 본 고안에 따른 유해 전자파 방지 전열선의 바람직한 실시예를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the harmful electromagnetic wave prevention heating wire according to the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 고안에 따른 일실시예로서 전열선 외관도를 나타낸 것이고, 도 4 및 도 5는 본 고안에 따른 일실시예로서 전열선의 부분 확대 단면도 및 종 단면도를 각각 나타낸 도면이다.3 is a view showing the outer appearance of the heating wire as an embodiment according to the present invention, Figures 4 and 5 is a view showing a partial enlarged cross-sectional view and a longitudinal cross-sectional view of the heating wire as an embodiment according to the present invention, respectively.

즉, 도 2 내지 도 5로 도시된 바와같이 본 고안의 전열선은 열선(1)과 적어도 복수가닥의 절연사(2a-2c)를 나선형태로 꼬운다음 그 둘레에 온도감지선(3)을 일정간격으로 권선하고, 다시 권선된 온도감지선의 외둘레에 일정두께의 절연피(4)를 피복한 전열선에 있어서, 상기 절연피(4)의 외둘레에 열선(1)의 길이방향으로 다수가닥의 에나멜선(10)을 망상체로 엮어 꼬임된 형태로 연속 권선한후, 2차로 절연피(20)을 피복하여서 구성된 것이다.That is, as shown in FIGS. 2 to 5, the heating wire of the present invention twists the heating wire 1 and at least the plurality of strands of insulated yarns 2a-2c in a spiral shape, and then heats the temperature sensing wire 3 around the wire. In the heating wire wound at intervals and coated with a constant thickness insulating skin (4) on the outer circumference of the temperature sensing wire wound again, a plurality of strands in the longitudinal direction of the heating wire (1) on the outer circumference of the insulating skin (4) After enameled wire 10 is woven into a reticular body and continuously wound in a twisted form, it is constructed by covering the insulating skin 20 secondly.

이에, 상기 다수가닥로 엮음되는 에나멜선(10)의 권선간격은 온도감지선(3)의 권선간격보다 좁은 형태의 망상체로 조밀하게 권선되어지므로서, 그 권선량에 의해 자계의 세기가 증대되어 유해 전자파의 감쇠 영역범위를 확대시키게 되는 것이고, 또한 꺾임 등의 외부충격에 대해서도 에나멜선이 다수가닥에 의해 엮음 권선되어지므로서 전열선이 절단 또는 쉽게 손상되지 않는 강인한 내구성을 갖게 되는 것이며, 이때 전열선을 형성되게하는 구성으로서 절연사(2a-2c) 및 절연피(4)(20)는 내열성이 강하고 구부림이 유연한 경질의 합성수지를 사용하게 되는 것이다.Accordingly, since the winding interval of the enameled wire 10 woven in the multiple strands is densely wound into a reticular body having a shape narrower than the winding interval of the temperature sensing line 3, the strength of the magnetic field is increased by the winding amount. The attenuation area of harmful electromagnetic waves is expanded, and the enameled wire is wound by multiple strands against external shock such as bending, so that the heating wire has strong durability that is not cut or easily damaged. The insulating yarns 2a-2c and the insulating skins 4 and 20 are formed of hard synthetic resins having strong heat resistance and flexible bending.

상기와 같이 구성되기 까지 전열선의 제조공정에 있어서는, 제5도에 나타낸 바와같이 보빈(30a)에 감긴 열선(1)과, 또 다른 보빈(30b-30d)에 감긴 절연사(2a-2c)를 꼬임기(35)에 넣은 상태에서 일정속도로 꼬임기(35)를 동작시키면 열선(1)과 절연사(2a-2c)는 나선형태로 꼬임되면서 꼬임의 절연사(2a-2c)에 의한 열선(1)은 외부로 붙터 밀봉된 상태가 된다.In the manufacturing process of a heating wire until it is comprised as mentioned above, as shown in FIG. 5, the heating wire 1 wound by the bobbin 30a, and the insulating yarn 2a-2c wound by another bobbin 30b-30d are wound. When the twister 35 is operated at a constant speed while being put in the twister 35, the heating wire 1 and the insulated yarns 2a-2c are twisted in a spiral shape while being heated by the insulated yarns 2a-2c of the twist. (1) is stuck to the outside and is sealed.

이와같이 밀봉 꼬임된 열선(1)과 절연사(2a-2c)는 다음 공정의 권선 및 피복기(40)를 통해서 절연사(2a-2c) 외둘레에 온도감지선(3)을 일정간격으로 권선함과 동시 온도감지선(3)이 권선된 외둘레를 일정두께의 절연피(4)로 압착피복하여 열선(1)과 온도감지선(3)이 일체로 된 전열선이 형성된다.The sealed twisted heating wire 1 and the insulated yarn 2a-2c are wound around the temperature sensing wire 3 at a predetermined interval on the outer circumference of the insulated yarn 2a-2c through the winding and sheath 40 of the following process. The outer circumference at which the temperature sensing wire 3 is wound is crimped and coated with an insulating sheath 4 having a predetermined thickness to form a heating wire in which the heating wire 1 and the temperature sensing wire 3 are integrated.

이후, 다음공정으로 열선(1)과 온도감지선(3)이 일체로 된 전열선과, 또 다른 보빈(30a)에 감긴 다수가닥의 에나멜선(10)을 권선 및 피복기(45)에 공급하면 권선 및 피복기(45)는 절연피의 외둘레에 에나멜선(10)을 망상체로 엮으며 조밀하게 권선함과 동시 권선된 외둘레를 별도의 수지공급에 의해 절연피(20)로 피복구성하여 본 고안의 전열선을 제조한다.Subsequently, when the heating wire 1 and the temperature sensing wire 3 are integrated into the next process, and a plurality of strands of enameled wire 10 wound on another bobbin 30a are supplied to the winding and the covering device 45. Winding and sheathing machine 45 is entwined enameled wire 10 in the outer periphery of the insulating skin, the winding tightly and the outer winding wound at the same time with a separate resin supply to cover the insulating skin (20) The heating wire of the invention is manufactured.

이와같은 공정에 의해 제조된 전열선의 작용 및 효과를 사용실시예로서 설명하면,Referring to the operation and effect of the heating wire produced by such a process as a working example,

먼저, 도 3내지 도 4와 같은 본 고안의 전열선의 열선(1) 양 끝단에 기존과 같이 입력전원을 연결하고, 온도감지선(3)의 양 끝단은 도시생략된 전자제어회로에 연결한 후, 전원을 공급하면 열선(3)으로 부터는 전기에너지를 열에너지로 변환하여 열원을 제공하게 되고, 그 열원은 온도감지센서(3)에 의해 감지되어 도시생략된 전자회로에 전기신호로서 전달된다.First, the input power is connected to both ends of the heating wire (1) of the heating wire of the present invention as shown in FIGS. 3 to 4, and both ends of the temperature sensing wire (3) are connected to the electronic control circuit, not shown. When the power is supplied, the electric wire is converted into heat energy from the heat wire 3 to provide a heat source, and the heat source is sensed by the temperature sensor 3 and transmitted to the electronic circuit, not shown.

이와같은 동작은 기존과 같이 전자제어회로에 의해 설정된 온도이하에서는 전원을 열선(1)에 공급하여 발열 동작하도록 하고, 설정온도에 도달하면 열선(1)에 공급하던 전원을 차단하도록 동작한다.In this operation, the power is supplied to the heating wire 1 at a temperature lower than the temperature set by the electronic control circuit as described above, and when the set temperature is reached, the power supply to the heating wire 1 is cut off.

이때에도 기존과 마찬가지로 설정된 온도 이하에서 발열동작되는 열선(1)으로 부터는 온도가 상승할수록 열에 의한 전자나 이온이 불규칙한 전자적인 교란작용에 의해 열잡음성 전자기파가 발생하게 된다.In this case, as in the prior art, as the temperature rises from the heating wire 1 that generates heat below the set temperature, thermal noise electromagnetic waves are generated by the electromagnetic disturbance of irregular electrons or ions due to heat.

이에, 열선(1)에서 발생되는 열잡음성 전자기파는 전자기복사의 이론과 파동의 성질에 의해 다른 영역의 공간으로 전파되는 성질을 갖고 있으므로서, 이 전자기파는 열선(1)의 다른 영역에 있는 즉 절연피(4)의 외둘레에 망상체로 엮이며 권선된 에나멜선(10)측에 전파유도된다.Therefore, the thermal noise electromagnetic wave generated in the heating wire 1 has the property of propagating to the space of another region according to the theory of electromagnetic radiation and the nature of the wave, so that the electromagnetic wave is in the other region of the heating wire 1, that is, is insulated. It is woven into a mesh on the outer circumference of blood (4) and is propagated to the wound enamel wire 10 side.

이때 에나멜선(10)에 전파 유도되는 전자기파는 열선(1)의 온도증감 작용에 따라 온도감지선(3)의 온도감지전류가 변화되는 제백효과(열전기력)에 의해 온도가 변화되는 에나멜선(10)의 임의점으로부터 열전기력 또는 열전류로 형성되어 흐르게 되며, 그 열전기력 또는 열전류의 흐름방향은 플레밍의 왼손법칙에 의해 에나멜선(10)의 힘을 받는 방향의 직각방향이면서 자력선(자계)의 위상보다 90°앞선 방향으로 흐르게 된다.At this time, the electromagnetic wave propagated to the enamel wire 10 is enameled wire (temperature of which is changed by the Seebeck effect (thermoelectric force) in which the temperature sensing current of the temperature sensing wire 3 changes according to the temperature increase and decrease action of the heating wire 1) It is formed by a thermoelectric force or a thermal current from any point of 10), and the flow direction of the thermoelectric force or the thermal current is perpendicular to the direction of receiving the force of the enamel wire 10 by the Fleming's left-hand rule, It will flow 90 ° ahead of phase.

이에 따른 망상체로 엮임되며 연속 권선된 에나멜선(10)은 이에 흐르는 열전기력 또는 열전류에 의해 자력선(자계)을 생성하게 되는데, 이 자력선(자계)은 전술한 바와 같이 열선(1)의 온도변화와, 이 온도변화에 비례적으로 변화 생성되는 열기전력 또는 열전류를 늘리거나, 줄이게 되며 그에 따라 증감되는 작용으로 생성되며, 생성된 자력선(자계)의 방향은 에나멜선(10)이 힘을 받는 방향의 직각방향이면서 열전기력 또는 열전류 방향보다 위상이 90°뒤진 방향으로 흐르게 된다.In this way, the enameled wire 10 woven in the reticular structure and continuously wound generates a magnetic force line (magnetic field) by a thermoelectric force or a thermal current flowing therethrough, and the magnetic force line (magnetic field) is formed as described above with respect to the temperature change of the heating wire 1. In addition, the increase or decrease of the thermal power or thermal current generated in proportion to the change in temperature is generated by the action of increasing or decreasing accordingly, and the direction of the generated magnetic force line (magnetic field) is the direction in which the enamel line 10 receives the force. It is perpendicular and flows in a direction 90 ° behind the thermoelectric or thermal current.

따라서, 상기와 같이 에나멜선(10)에서 생성되는 자력선(자계)은 망상체로 엮음 권선된 에나멜선(10)이 인덕턴스로 작용하여 열선(1)에서 다른 영역으로 방출되는 전파성 열잡음 전자기파를 1차적으로 감쇠 및 중화시키는 작용을 하게 된다.Therefore, the magnetic force line (magnetic field) generated by the enamel wire 10 as described above primarily acts as an inductance of the enamel wire 10 wound into a reticular body and induces radio wave thermal noise electromagnetic waves emitted from the heating wire 1 to another region. It acts as attenuation and neutralization.

이와 동시에 에나멜선(10)에 흐르는 열기전력 또는 열전류는 전원단의 접지극에 연결되어 있을 경우에는 2차적으로 전원단의 접지극을 통해 건물대지의 접지로 흐르도록 동작하게 된다.At the same time, the thermoelectric power or the thermal current flowing through the enamel wire 10 is secondly operated to flow to the ground of the building ground through the ground electrode of the power terminal when connected to the ground electrode of the power terminal.

In this configuration, the aluminum strip 10 'has the same function as the reticulated enamel wire 10 of the above-described embodiment, and the insulation strip 4 is squeezed in a wide cross section so that harmful electromagnetic waves are neutralized and attenuated in a wide range. The wide band-like structure makes it possible to have durability that is not easily cut or damaged even against external impact such as bending.

또한, 이와같은 또 다른 실시예로서의 유해전자파 방지 전열선의 제조방법은 전술한 일실시예로서의 유해전자파 방지 전열선의 제조방법과 동일한 것으로, 단지 그 제조공정에 있어, 일실시예로서의 에나멜선(10)이 감긴 다수개의 보빈(30f-30m)을 알루미늄띠가 감긴 단일개의 보빈으로 교체하여 작업을 실시하므로서 이루어지고, 이에 따라 형성된 또 다른 실시예로서의 유해전자방지 전열선의 기능원리 및 사용관계 또한 전술한 일시예와 동일하게 인덕턴스로 작용되며 열선(1)에서 다른 영역으로 방출되는 전파성 열잡음 전자기파를 1차적으로 감쇠 및 중화시키는 작용을 하게 되고,In addition, the manufacturing method of the harmful electromagnetic wave protection heating wire as another embodiment as described above is the same as the manufacturing method of the harmful electromagnetic wave preventing heating wire as one embodiment described above, only in the manufacturing process, a number of wound enamelled wire 10 as an embodiment This is done by replacing the two bobbins (30f-30m) with a single bobbin wound around the aluminum strip, and the functional principle and use relationship of the anti-hazardous heating element as another embodiment thus formed are also the same as the above-described It acts as an inductance and acts primarily to attenuate and neutralize the propagating thermal noise electromagnetic waves emitted from the heating wire 1 to other areas,

이와 동시에 알루미늄띠(10')에 흐르는 열기전력 또는 열전류는 전원단의 접지극에 연결되어 있을 경우에는 2차적으로 전원단의 접지극을 통해 건물대지의 접지로 흐르도록 동작하게 된다.At the same time, when the thermoelectric power or the thermal current flowing through the aluminum strip 10 'is connected to the ground electrode of the power supply terminal, the thermoelectric power or the thermal current flows to the ground of the building ground through the ground electrode of the power supply terminal.

이상에서 설명한 바와 같이 본 고안의 전열선은 열선의 외둘레에 온도감지선과, 이 온도감지선의 외둘레에 망상체로 엮음된 에나멜선 내지 알루미늄띠를 권선한후, 절연피로 피복구성하여 열선에서 발생되는 열잡음성 전자기파를 전파유기되도록 하고, 또한 전원단의 접지극을 통해 외부방출이 이루어 지도록 하므로서 인체에 해로운 유해 전자파를 원초적으로 억제할수 있도록 한 것일뿐만 아니라, 에나멜선의 망상체 엮음구성 내지 알루미늄띠에 의한 구성으로 그 내구성을 향상되게하여, 전열선이 유동되며 꺾임되거나 외부충격을 받을경우에도 견고한 권선구성으로 제품의 사용수명을 연장시키는 등의 효과 또한 제공하게 되는 것이다.As described above, the heating wire of the present invention has a temperature sensing wire on the outer circumference of the heating wire, and an enamel wire or an aluminum strip wound with a reticulated body on the outer circumference of the heating wire, and then covered with insulation to form a thermal noise generated from the heating wire.
