Description

전기히터{Electric heater}Electric heater

본 고안은 전기히터에 관한 것으로, 특히 U자형 가열부를 매개로 유체를 직접 가열하도록 된 전기히터에 관한 것이다.The present invention relates to an electric heater, and more particularly to an electric heater adapted to directly heat the fluid through the U-shaped heating unit.

주지된 바와 같이, 전기히터는 전류에 의한 발열을 이용해서 가열하는 기구로서, 사용 목적과, 설치 대상, 가열매체의 종류, 처리용량 등의 요건에 따라서 다양한 형태의 것들이 개발되어 이미 널리 활용되고 있다.As is well known, electric heaters are a mechanism for heating by using heat generated by electric current, and various types of electric heaters have been developed and widely used according to the purpose of use, requirements for installation, types of heating media, processing capacity, and the like. .

이중, U자형 가열부를 매개로 유체를 직접 가열하도록 된 종래 전기히터는, 도 1에 도시된 바와 같이, 가열실(10a)과, 가열실(10a)에 연통되는 입·출구(11,12)가 구비되어진 하우징(10)과 ; 전기단자(20a)를 갖추고서 하우징(10)에 고정되는 연결부(20) 및; 전기단자(20a)에 접속되어진 전기 발열체가 내설되고, 하우징(10)의 가열실(10a) 내부에 배치되어, 가열실(10a) 내부의 유체를 직접 가열하는 U자 형태의 가열부(30)로 이루어진 구조를 이룬다.Among them, a conventional electric heater that directly heats a fluid via a U-shaped heating unit, as illustrated in FIG. 1, has an inlet and outlet 11 and 12 communicating with the heating chamber 10a and the heating chamber 10a. The housing 10 is provided; A connection part 20 having an electric terminal 20a and fixed to the housing 10; An electric heating element connected to the electric terminal 20a is installed inside the heating chamber 10a of the housing 10 and is U-shaped heating unit 30 for directly heating the fluid inside the heating chamber 10a. It consists of a structure consisting of.

이러한 종래 전기히터의 작동상태를 설명해 보면 다음과 같다.Referring to the operation of the conventional electric heater as follows.

상기 연결부(20)가 임의의 구조물에 고정되어진 상태에서, 전기단자(20a)를 통해서 전력 공급이 이루어지면, 전기단자(20a)에 접속되어진 전기 발열체가 가열되어서 이를 감싸고 있는 U자 형태의 가열부(30)가 고온으로 가열된다.In a state where the connection part 20 is fixed to an arbitrary structure, when power is supplied through the electric terminal 20a, an electric heating element connected to the electric terminal 20a is heated to surround the U-shaped heating part. 30 is heated to high temperature.

따라서, 상기 하우징(10)의 입구(11)를 통해서 외부로부터 가열실(10a) 내부로 유입되어진 유체는 가열부(30)에 직접 접촉되면서 고온으로 가열된 후에 하우징(10)의 출구(12)를 통해서 외부로 배출된다.Therefore, the fluid introduced into the heating chamber 10a from the outside through the inlet 11 of the housing 10 is heated to a high temperature while being in direct contact with the heating unit 30, and then the outlet 12 of the housing 10. It is discharged to the outside through.

그러나, 이러한 종래 전기히터는, 매끄럽게 표면처리된 U자 형태의 가열부(30)를 이용하고 있어서, 전열면적이 작고, 유체가 가열실(10a)로 별다른 저항없이 빠르게 유출입되므로, 열교환이 제대로 이루어지지 못하는 문제가 초래된다.However, such a conventional electric heater uses a U-shaped heating part 30 which is smoothly surface-treated, so that the heat transfer area is small and the fluid flows into and out of the heating chamber 10a quickly without any resistance. A lack of support will result.

이러한 문제를 해소하기 위해, 가열실(10a)의 면적을 확대해서 가열실(10a) 내에서의 유체의 흐름이 자연스럽게 천천히 흐르도록 하거나, 가열실(10a)로의 유량공급을 줄여서 유체가 천천히 공급되고 천천히 배출되도록 하고 있다.To solve this problem, the area of the heating chamber 10a is enlarged so that the flow of the fluid in the heating chamber 10a flows slowly, or the fluid is supplied slowly by reducing the flow rate to the heating chamber 10a. It is being discharged slowly.

하지만, 이러한 경우에도 열전도율 문제는 해소되지 못하여, 일정량의 유체를 일정한 온도로 가열하는데 많은 시간이 소요된다.However, even in such a case, the thermal conductivity problem cannot be solved, and it takes a long time to heat a certain amount of fluid to a constant temperature.

이에 본 고안은 상기와 같은 문제를 해소하기 위해서 안출된 것으로, 열전도율이 크게 향상시킬 수 있는 단순한 구조의 전기히터를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, the object of the present invention is to provide an electric heater of a simple structure that can significantly improve the thermal conductivity.

And; It forms a structure consisting of a metal foil 40 surrounding the circumferential surface of the heating unit 30.

상기 연결부(20)는 주변 구조물에 전기히터를 고정하거나, 전력공급을 위하여 전기소켓에 연결하기 위한 부분으로, 그 구조는 주변 구조물이나 전기소켓의 구조에 따라서 다양하게 변형될 수 있다.The connection part 20 is a part for fixing the electric heater to the peripheral structure, or for connecting to the electric socket for power supply, the structure can be variously modified according to the structure of the peripheral structure or the electric socket.

상기 가열부(30)는 열전도율이 우수하면서 잘 부식되지 않는 금속재질의 U자형 관에 전기 발열체가 내설되어진 구조를 이루는데, 전기 발열체는 통상 니켈·크롬 합금(니크롬선), 철·크롬·알루미늄 합금, 니켈·크롬·철 합금 등으로 제조된다.The heating part 30 has a structure in which an electric heating element is embedded in a U-shaped tube made of a metal material which is excellent in thermal conductivity and does not corrode well. Alloy, nickel, chromium, iron alloy and the like.

따라서, 상기 하우징(10)의 입구(11)를 통해서 외부로부터 가열실(10a) 내부로 유입되어진 유체는 가열부(30)와 금속박(40)에 직접 접촉되면서 빠르게 고온으로 가열된 후에 하우징(10)의 출구(12)를 통해서 외부로 배출된다.Therefore, the fluid introduced into the heating chamber 10a from the outside through the inlet 11 of the housing 10 is heated directly to a high temperature while directly contacting the heating unit 30 and the metal foil 40, and then the housing 10. Is discharged to the outside through the outlet (12).

본 고안에 따른 전기히터는, 가열부(30)의 둘레면이 금속박(40)을 매개로 감싸여진 구조를 이루므로, 전열면적의 증가로 인해서 열전도율이 크게 향상되고, 유체가 빠르게 고온으로 가열된다.In the electric heater according to the present invention, since the circumferential surface of the heating part 30 forms a structure surrounded by the metal foil 40, the thermal conductivity is greatly improved due to the increase in the heat transfer area, and the fluid is quickly heated to a high temperature. .

한편, 도 3에 도시된 바와 같이, 띠형태를 이루는 금속박(40)을 일정 간격(g2)이 유지되도록 가열부(30,30')에 나선형으로 감싸면, 입구(11)를 통해서 유입되어진 유체가 나선형의 금속박(40)에 부딪히면서 출구(12)쪽으로 자연스럽게 유도되고, 금속박(40) 사이의 간격(g2)을 통해 자유롭게 유출입되어 가열실(10a) 내부에 와류가 발생된다.Meanwhile, as shown in FIG. 3, when the metal foil 40 having a band shape is spirally wrapped in the heating parts 30 and 30 ′ so that a predetermined distance g2 is maintained, the fluid introduced through the inlet 11 is While hitting the spiral metal foil 40, it is naturally guided toward the outlet 12, and freely flows in and out through the gap g2 between the metal foils 40 to generate vortices inside the heating chamber 10a.

따라서, 본 실시예에 따르면 유체의 가열이 보다 빠르고 효과적으로 이루어지게 된다.Therefore, according to this embodiment, the heating of the fluid is made more quickly and effectively.
