Description
본 고안은 온수가열통의 상부 중앙부와 순환수저장통의 하부 중앙부에 역지밸브 또는 플로트밸브를 결합시켜 버너 등의 가열기로 가열시킨 온수가열통 내부의 가열수에 의하여 발생되는 고온의 증기를 이용하여 열교환 효율을 최대한 높일 수 있도록 고안된 증기압을 이용한 난방용 간이 열교환기에 관한 것이다.The present invention combines the check valve or the float valve in the upper center portion of the hot water heater and the lower center of the circulation water reservoir to heat the heat using hot steam generated by the heating water inside the hot water heater heated by a heater such as a burner. The present invention relates to a simple heat exchanger for heating using steam pressure designed to maximize efficiency.
종래에 난방용 간이열교환기에 있어서의 증기압을 이용한 열교환기는 없었다. 그러나 온수보일러형 열교환기는 제안된바 있었다. 이와같은 종래의 온수보일러형 열교환기에 있어서는 가열통과 기화통 및 냉각통을 흡입관과 냉각수유출관으로 결합하여 기화실에는 시이소형 구조의 냉각수공급장치를 설치하여 별도의 냉각수를 공급하여 주므로서 냉각수가 가열통 내부의 증기압에 의해 응축작용(삼투작용)을 하면서 가열수가 시차적으로 열교환 할 수 있도록 결합된 구조로서 가열통과 기화통 및 냉각통의 물의 용적비율의 정도에 따라 작동하게 되므로, 기화통 내부의 중량추와 냉각수 공급장치의 구조가 복잡함은 물론 고도의 정밀성이 요구되었다.In the past, there was no heat exchanger using vapor pressure in a simple heat exchanger for heating. However, hot water boiler type heat exchangers have been proposed. In the conventional hot water boiler type heat exchanger, the heating tank, the vaporization cylinder, and the cooling cylinder are combined with the suction pipe and the cooling water outlet tube, and the cooling water is supplied by supplying a separate cooling water by installing a coolant supply device having a seesaw type structure in the vaporization chamber. The condensation action (osmotic action) is caused by the steam pressure inside the tank, so that the heated water can be heat-exchanged differentially.It operates according to the volumetric ratio of the water in the heating cylinder, the vaporization cylinder, and the cooling cylinder. The complexity of the weight and coolant supply was required as well as a high degree of precision.
이와 같은 종래의 온수 보일러형 열교환기는 구조가 복잡하여 제작 비용이 많아 비경제적인 결점이 있었으며, 특히 가열수에 의하여 열교환을 하고 있으므로 열교환의 효율이 미흡한 결점이 있었다.Such a conventional hot water boiler type heat exchanger has a complicated structure and a large manufacturing cost, and thus has an uneconomical disadvantage. In particular, since the heat exchange is performed by heated water, there is a disadvantage that the efficiency of heat exchange is insufficient.
본 고안의 종래의 결점을 적게 하기 위하여 온수가열통과 순환수저장통 간에 역지밸브를 결합시킨 순환수 송출관을 설치하되, 역지밸브를 결합시킨 순환수 송출관을 순환수 저장통 내부 용적수의 중량과 온수가열통 내부의 증기압 정도에 의한 가열수의 가상수위에 가까운 가열수의 정상수위의 하부에 위치하도록 설치하여 부피를 최소화 할 수 있는 간단한 구조로서 가열수의 정상수위 상부가 되는 증기압부에서 발생되는 고온의 증기압에 의하여 열교환의 효율을 극대화 할 수 있도록 하며, 일반가정에서나 캠핑시에 텐트의 내부바닥 등 실내외에 구애됨이 없이 난방용 침구나 방석 등의 난방용 열교환기(증기 순환호스)로서 간이용으로 간편하고 용이하게 사용할 수 있도록 함에 목적이 있다.In order to reduce the conventional drawbacks of the present invention, a circulating water discharge pipe combining a check valve is installed between a hot water heating tank and a circulating water storage tank, and the weight of the volumetric water inside the circulating water reservoir and the hot water It is a simple structure that can minimize the volume by installing the heater at the lower part of the normal level of the heating water close to the virtual level of the heating water by the degree of steam pressure inside the heater. The high temperature generated in the steam pressure part that is the upper part of the normal level of the heating water. It is possible to maximize the efficiency of heat exchange by the steam pressure, and it is convenient for simple use as a heat exchanger (steam circulation hose) for heating bedding and cushion, etc. The purpose is to make it easy to use.

이와 같은 본 고안은 증기압실(A)을 형성하는 온수가열통(1)의 저면부를 버너등의 가열기(11)에 의하여 가열하게 되면 급속가열판(11a)에 의하여 온수가열통(1) 내부의 가열수(14)가 급속 가열되어 가열수의 정상수위(15)의 상부인 증기압실(A)에 증기압이 발생된다.The present invention is such that when the bottom portion of the hot water heater (1) forming the vapor pressure chamber (A) is heated by a heater 11 such as a burner, the heating inside the hot water heater (1) by the rapid heating plate (11a). The water 14 is rapidly heated to generate steam pressure in the vapor pressure chamber A, which is the upper part of the normal water level 15 of the heated water.
이와 같은 증기압은 순환수 송출관(5a)의 내부에 설치된 역지밸브(5)를 가압하면서 역지밸브(5)를 밀폐시키고, 고온 상태의 수증기로서 개폐콕(18)이 개방된 증기이송관(7)으로 가압이송되어 내열성 중간호스(8)에 의하여 내열성 난방용 호스인 열교환기(9)를 따라 통과하면서 열교환 됨으로서 텐트(12)의 내부바닥에 깔아놓은 자리판(9a)을 데워주게 된다.Such steam pressure pressurizes the check valve 5 installed inside the circulating water delivery pipe 5a to seal the check valve 5, and the steam transfer pipe 7 having the opening and closing cock 18 open as steam at a high temperature. The heat transfer is carried out by the heat-resistant intermediate hose (8) to pass through the heat exchanger (9) which is a heat-resistant heating hose to heat the seat plate (9a) laid on the inner bottom of the tent (12).
간이콕(21)은 필요시에 더운물을 사용할 때 개폐할 수 있다. 다음은 온수가열통(1) 내부의 가열수의 정상수위(15)가 높은 상태이고 순환수 저장통(2)내부의 순환수의 정상수위(17)가 낮은 상태를 시점으로 하여 작용상태를 설명한다.The simple cock 21 can be opened and closed when hot water is used if necessary. Next, the operation state will be described with a state in which the normal water level 15 of the heating water inside the hot water heating tank 1 is high and the normal water level 17 of the circulating water in the circulation water storage tank 2 is low. .
온수가열통(1)내부의 가열수(14)를 가열함으로서 발생되는 증기압실(A)의 고온의 증기(Aa)를 가압송출시킴에 따라 텐트(12)의 내부바닥에 깔아놓은 자리판(9a)을 데워주면서, 열교환된 고온의 증기(Aa)는 열교환기(9)를 통과하는 동안 열교환 된 후 순환수(16)로서 순환수 환수관(6)을 통하여 계속하여 순환수 저장탱크(2)의 내부로 입수되어 순환수 저장탱크(2) 내부의 순환수의 정상수위(17)가 점차 높아지는 반면에 온수가열통(1) 내부의 가열수(14)의 정상수위(15)는 점차 낮아지게 되는데, 이때 상기 순환수(16)의 정상수위(17)와 가열수(14)의 정상수위(15)의 높고 낮음이 되는 순환수(16)의 입수량은 가열수(14)를 가열하여 고온의증기(Aa)상태로 송출되어 열교환된 후 액화상태의 액화량과 동일한 비율로 작용하게 된다.The seat plate 9a laid on the inner bottom of the tent 12 by pressurizing the hot steam Aa of the vapor pressure chamber A generated by heating the heated water 14 inside the hot water heater 1. ), The heat exchanged high temperature steam (Aa) is heat exchanged while passing through the heat exchanger (9), and then continues through the circulating water return pipe (6) as the circulating water (16) circulating water storage tank (2) The normal water level 17 of the circulating water in the circulation water storage tank 2 is gradually increased while the normal water level 15 of the heating water 14 inside the hot water heating tank 1 is gradually lowered. In this case, the amount of the circulating water 16 which is high and low of the normal water level 17 of the circulating water 16 and the normal water level 15 of the heating water 14 is heated to a high temperature by heating the heating water 14. After being sent to the steam (Aa) state and heat exchanged, it acts at the same ratio as the liquefaction amount of the liquefied state.
이와 같은 작용을 계속하면서 온수가열통(1) 내부의 가열수의 정상수위(15)가 낮아지면서 가열수의 가상수위(15a)에 까지 이르게 됨에 따라서 순환수저장통As the normal water level 15 of the heating water inside the hot water heating tank 1 is lowered while the operation is continued, the circulation water storage tank reaches the virtual water level 15a of the heating water.
(2) 내부의 순환수의 정상 수위(17)가 높아지게 되어 순환수의 가상수위(17a)까지 이르게되면, 순환수(16)의 수압이 높아지게 됨에따라 가열수의 가상수위(15a)의 상부인 증기압실(A)로부터 발생되는 고온의 증기압의 응축작용에 의하여 순환수(16)의 수압이 순환수송출관(5a)을 통하여 온수가열통(1)의 중앙 최상내부(3)에 설치한 역지밸브(5)를 가압하여 역지밸브(5)를 개방시킴과 동시에 순환수 저장통(2) 내부의 순환수(16)가 온수가열통(1)의 내부로 흡입하게 되어 상기 온수가열통(1) 내부의 가열수의 가상수위(15a)가 다시 가열수의 정상수위(15)의 상태로 이르게 된다.(2) When the normal water level 17 of the circulating water is increased to reach the virtual water level 17a of the circulating water, the water pressure of the circulating water 16 is increased, which is the upper part of the virtual water level 15a of the heating water. The check valve provided with the water pressure of the circulating water 16 at the uppermost inner center 3 of the hot water heating tube 1 through the circulating water delivery pipe 5a by the condensation action of the high temperature steam pressure generated from the vapor pressure chamber A. (5) pressurizes to open the check valve (5) and at the same time the circulating water 16 in the circulation water reservoir (2) is sucked into the hot water heater (1) inside the hot water heater (1) The virtual water level 15a of the heated water again leads to the state of the normal water level 15 of the heated water.
이와 같은 작용을 계속하면서 가열되는 가열수(14)를 가열하면서 발생되는 고온의 증기(Aa)를 개폐콕(18)이 개방된 증기이송관(7)으로 이송시키면서 계속하여 상기의 열교환 작용을 반복 연속한다.The above heat exchange operation is continuously repeated while transferring the high temperature steam Aa generated while heating the heated water 14 to be heated while continuing the above operation to the steam transfer pipe 7 with the opening / closing cock 18 open. do.
이와 같은 작용은 상기 역지밸브(5)를 밀폐 개방하고 있는 온수가열통(1)의 증기압실(A)에서 발생되는 증기압과 순환수저장통(2)의 순환수(16)의 용량에 의한 수압과의 상관 관계에 의하여 이루어진다.This action is due to the water pressure due to the steam pressure generated in the steam pressure chamber (A) of the hot water heating tank (1), which opens and closes the check valve (5), and the capacity of the circulating water (16) of the circulation water storage tank (2). By correlation.
