일반적으로 난방용수는 보일러에 의해 가열되어 순환되며, 이러한 난방용수를 샤워나 기타 가정내에서 필요한 온수로서 사용하기에 과도하게 가열된 상태여서 부적합하므로 난방용수와는 별도로 온수를 공급할 필요가 있으며, 온수를 사용하는 동안에는 난방용수 공급이 중단되는 문제가 있게 된다. 이러한 문제를 해결하기 위하여 난방용수는 그 배관을 지나는 동안 보일러 버너에 의해 직접 가열되게 하는 한편, 그 난방용수와 열교환을 통해 직수를 간접가열하여 온수로서 사용할 수 있도 록 하는 온수열교환기를 보일러에 설치하고 있다.In general, the heating water is heated and circulated by the boiler, and it is necessary to supply hot water separately from the heating water because the heating water is not suitable because it is excessively heated to be used as a hot water necessary for a shower or other household. There is a problem that the heating water supply is interrupted while using. In order to solve this problem, the heating water is directly heated by the boiler burner while passing through the pipe, while the hot water heat exchanger is installed in the boiler so that it can be used as hot water by indirectly heating the water through the heat exchange with the heating water. have.

이러한 종래의 온수열교환기의 예로서 본 출원인의 실용신안등록 제20-0310318호의 "보일러용 온수열교환기" 에는 도 1의 분해사시도와 도 2의 난방수 유로를 보여주는 단면도, 도 3의 온수 유로를 보여주는 단면도에서 볼 수 있듯이, 열교환면적을 증대시키기 위한 요철비드(50)가 전역에 걸쳐 포밍된 열교환판(10)들과, 상기 열교환판(10)들의 상부에 배치되며 직수 입ㆍ출구(21)(22) 및 난방수 입ㆍ출구(23)(24)가 코너부위에 형성된 상판(20)과, 상기 상판(20)의 직수 입구(21)와 대응하는 상기 열교환판(10)들의 코너부위에 형성되어 상기 직수유로(40)들을 상호 연통시키는 제1연통공(11)과, 상기 상판(10)의 직수 출구(22)와 대응하는 상기 열교환판(10)들의 코너부위에 형성되어 상기 직수유로(40)들을 상호 연통시키는 제2연통공(12)과, 상기 상판(20)의 난방수 입구(23)와 대응하는 상기 열교환판(10)들의 코너부위에 형성되어 상기 난방수유로(30)들을 상호 연통시키는 제3연통공(13)과, 상기 상판(20)의 난방수 출구(24)와 대응하는 상기 열교환판(10)들의 코너 부위에 형성되어 상기 난방수유로(30)들을 상호 연통시키는 제4연통공(14)을 갖춘 보일러용요부와 융기부가 번갈아 형성된 동일 형상의 열교환판들이 서로 반대방향으로 배치되는 방식으로 적층되어 용접됨으로써 열교환판들 사이에 용접되어 난방수유로(30)와 직수유로(40)가 상호 번갈아가면서 형성된 구성이 개시되어 있다.As an example of such a conventional hot water heat exchanger, the "hot water heat exchanger for boilers" of Korean Patent Application No. 20-0310318 of the applicant has a cross-sectional view showing an exploded perspective view of FIG. 1 and a heating water flow path of FIG. As can be seen in the cross-sectional view, the uneven bead 50 for increasing the heat exchange area is formed over the heat exchange plate 10 and the heat exchange plate 10 formed on the whole, and the direct inlet and outlet 21 (22) and heating water inlet / outlet (23) (24) formed at the corners of the upper plate 20, and the corner portion of the heat exchange plate (10) corresponding to the direct inlet (21) of the upper plate (20) A first communication hole 11 formed to communicate with the direct flow passages 40, and formed at a corner of the heat exchange plates 10 corresponding to the direct outlet 22 of the upper plate 10. The second communication hole 12 for communicating with each other (40), and the heating water inlet 23 of the upper plate 20 and A third communication hole 13 formed at corners of the corresponding heat exchange plates 10 to communicate the heating water passages 30 with the heating water outlet 24 of the upper plate 20. Heat exchanger plates having the same shape and alternately formed with a main recess and a ridge having a fourth communication hole 14 formed at corners of the heat exchanger plates 10 to communicate the heating water flow passages 30 with each other are arranged in opposite directions. Laminated and welded in such a way as to be welded between the heat exchange plate is disclosed a configuration in which the heating water channel 30 and the direct water channel 40 are formed alternately with each other.

또한, 본 출원인의 등록실용신안 20-0437768호의 "보일러용 온수열교환기의 열교환판"에서는 도 4에 도시된 바와같이 열교환판(10a)(10b)들의 상부에 V자 형으로 다수개가 일정간격으로 형성된 요철부(50)와, 상기 요철부(50)의 상부에 일정간 격으로 물이 잘 흐르도록 유로홈(51)을 형성하고, 상기 요철부(50)와 요철부(50) 사이의 홈에 일정간격으로 돌출되게 돌출리브(52)를 형성하여 난방수와 직수가 상기 유로홈(51)을 통하여 직선으로도 통과하도록 형성하였다.In addition, in the applicant's registered utility model No. 20-0437768, "Heat exchanger plate of hot water heat exchanger for boiler", as shown in Figure 4, a plurality of V-shaped on the top of the heat exchange plate (10a) (10b) at regular intervals. The concave and convex portions 50 and the concave and convex portions 50 are formed on the upper portions of the concave and convex portions 50 so that water flows well at regular intervals, and the grooves between the concave and convex portions 50 and the concave and convex portions 50 are formed. Protruding ribs 52 were formed to protrude at a predetermined interval in the heating water and the direct water was also formed to pass through the flow path groove 51 in a straight line.

그러나, 상기 등록고안들에서 동일한 열교환판들을 적층한 구조로 되어 난방수 인입구와 배출구 사이의 직선 유로를 중심으로 난방수와 직수가 유동하게 되므로 열교환판 전체 면적에 대해 균일하게 열교환이 이루어지지 못하게 됨에 따라 열교환 효율이 낮기 때문에 난방용수와 직수의 흐름이 열교환판 전체 면적에 대해 보다 균일하게 분산되어 유동할 수 있도록 함으로써 열교환 효율의 향상 및 온수를 보다 신속히 생성할 수 있는 구조 개선이 요구되었다.However, since the same design of the heat exchanger plates are laminated in the registration proposals, the heating water and the direct water flow around the straight flow path between the heating water inlet and the outlet so that heat exchange is not uniformly performed over the entire area of the heat exchanger plate. Accordingly, since the heat exchange efficiency is low, the flow of heating water and direct water are more uniformly distributed over the entire area of the heat exchange plate, thereby improving the heat exchange efficiency and improving the structure to generate hot water more quickly.

본 발명의 목적은 상기한 종래의 보일러용 온수열교환기에서의 열교환판에 대한 문제점을 해결하여 난방수와 직수의 흐름을 분산시켜 열교환판 전체 면적에서 열교환이 이루어지도록 개선된 구조의 온수 열교환기용 열교환판을 제공하는 것이다.An object of the present invention is to solve the problem of the heat exchange plate in the conventional hot water heat exchanger for the boiler by distributing the flow of heating water and direct water heat exchanger for the hot water heat exchanger of the improved structure so that the heat exchange in the entire area of the heat exchange plate To provide a plate.

본 발명의 다른 목적은 상기한 개선된 구조의 열교환판을 이용하여 보다 신속하게 온수를 생성하도록 개선된 온수 열교환기를 제공하는 것이다.Another object of the present invention is to provide an improved hot water heat exchanger to produce hot water more quickly by using the heat exchanger plate of the improved structure described above.

상기 목적을 달성하기 위한, 본 발명의 온수 열교환기용 열교환판은 직수와 난방수 인입, 배출구들이 형성되고 요부와 마루 부분들이 형성된 온수열교환기용 열교환판에 있어서, 상면에 평탄한 마루부분들이 일정 간격으로 이격되어 형성됨과 함께 그 마루부분들에서 전측으로 동일 평면상으로 연장된 연장부분들이 일정 간격 이격되어 형성되며, 상기 연장부들 사이는 요홈으로 형성되어 그 저면측에 형성되는 난방수 유로의 압력강하가 완화되도록 된 것을 특징으로 하여 구성된다.In order to achieve the above object, the heat exchanger plate for hot water heat exchanger of the present invention is a heat exchanger plate for hot water heat exchanger having direct water and heating water inlet, outlets formed and recesses and floor portions, wherein the flat floor portions on the upper surface are spaced at regular intervals. While extending from the floors, the extending parts extending in the same plane from the floor are spaced apart at regular intervals, and the pressure drop of the heating water flow path formed on the bottom side of the extension parts is relieved. It is characterized by the above-mentioned.

상기 마루부분들은 난방수 인입구와 배출구 사이의 직선 영역에서의 마루부분의 폭(d1)이 그 반대쪽의 곡선 영역에서의 마루부분의 폭(d2) 보다 작게 형성된 것이 바람직하며, 상기 열교환판의 상면에 형성되는 직수체적보다 저면측에 형성되는 난방수용 체적이 더 크게 형성되는 것이 바람직하다.Preferably, the floor portions are formed such that the width d1 of the floor portion in the linear region between the heating water inlet and the outlet is smaller than the width d2 of the floor portion in the curved region on the opposite side thereof. It is preferable that the volume for heating water formed on the bottom face side is larger than the formed water volume.

본 발명에 의한 열교환판을 이용한 온수 열교환기는, 직수와 난방수 인입, 배출구들이 형성되고 요부와 마루 부분들이 형성된 복수개의 열교환판들을 이격되게 적층 배치하여 그 열교환판들 사이에 난방수와 직수 유로가 형성되어 보잉러에 의해 가열되어 공급되는 난방수와의 열교환에 의해 온수를 생성하도록 된 온수열교환기에 있어서, 상면에 평탄한 마루부분들이 일정 간격으로 이격되어 형성됨과 함께 그 마루부분들에서 전측으로 동일 평면상으로 연장된 연장부분들이 일정 간격 이격되어 형성되며, 상기 연장부들 사이는 요홈으로 형성되어 그 저면측에 형성되는 난방수 유로의 압력강하가 완화되도록 된 열교환판을 피시본 형태로 요철부가 형성된 열교환판을 교대로 이격되게 적층배치하여 형성된 것을 특징으로 하여 구성된다.Hot water heat exchanger using a heat exchanger plate according to the present invention, the heat and direct flow path between the heat exchanger plate is formed by stacking a plurality of heat exchanger plates formed with direct water and heating water inlet, outlets and recesses and floors are spaced apart In the hot water heat exchanger is formed to generate hot water by heat exchange with the heating water supplied by the Boeing Boiler, the flat floors on the top surface is formed spaced at regular intervals and the same plane in front of the floor parts The extended portions extending upward are spaced apart at regular intervals, and the heat exchange plate having the uneven portion in the form of a fishbone is formed in the heat exchange plate to form a recess between the extension portions to reduce the pressure drop of the heating water flow path formed on the bottom surface side thereof. The plates are alternately spaced apart from each other and formed.

본 발명에 따른 열교환판은 열교환판 전체에 걸쳐 유체가 고르게 분산되고, 저면측의 난방수의 흐름이 상면측의 직수의 흐름보다 더 원활하게 이루어지도록 형성되며, 이러한 열교환판을 기존의 피시본 형태의 열교환판과 결합하여 구성되는 온수 열교환기는 난방수와 직수의 온도차가 크게 유지되어 열교환 효율이 향상되고 온수가 신속히 형성되는 효과가 있다. The heat exchange plate according to the present invention is formed so that the fluid is evenly distributed throughout the heat exchange plate, and the flow of heating water on the bottom side is made more smoothly than the flow of the direct water on the upper side. The hot water heat exchanger is configured in combination with the heat exchanger plate of the hot water is directly maintained the temperature difference between the heating water is improved heat exchange efficiency and there is an effect that the hot water is formed quickly.

일반적으로, 판을 사이에 두고 이루어지는 열전달 열량은 아래 식으로 표현될 수 있다.In general, the heat transfer amount of heat formed between the plates can be expressed by the following equation.

q= (Ka ×ΔT×A)/ΔXaq = (Ka × ΔT × A) / ΔXa

여기서, q는 이동열량, Ka는 판의 열전달계수, ΔT는 온도차, A는 판의 면적, ΔXa는 판두께이다.   Where q is the amount of heat transferred, Ka is the heat transfer coefficient of the plate, ΔT is the temperature difference, A is the area of the plate, and ΔXa is the plate thickness.

위 식으로부터 판을 사이에 두고 이루어지는 열전달에서 이동열량은 판 양측에서의 온도차와 면적에 비례함을 알 수 있으므로, 열교환기에서의 열전달율은 난방수와 직수와의 접촉면적과 난방수와 직수의 온도차에 비례함을 알 수 있다. 난방수 온도가 동일한 경우 난방수가 열교환판의 인입구로 인입되어 배출구를 통해 유동하는 동안 난방수가 열교환에 의해 온도가 저하될 것이므로 난방수의 유속이 증가되면 상기 난방수와 직수의 온도차를 보다 크게 유지할 수 있게 될 것이고 이에 따라 열교환 효율도 개선될 것이다. From the above equation, it can be seen that the amount of heat transfer in the heat transfer between the plates is proportional to the temperature difference and the area on both sides of the plate. Therefore, the heat transfer rate in the heat exchanger is the contact area between the heating water and the direct water, and the temperature difference between the heating water and the direct water. It can be seen that it is proportional to. If the heating water temperature is the same, the heating water will be lowered by the heat exchange while the heating water enters the inlet of the heat exchange plate and flows through the outlet, so that the temperature difference between the heating water and the direct water can be kept larger when the flow rate of the heating water is increased. This will improve heat exchange efficiency.

본 발명의 열교환판은 상기한 관점에서 직수와 비교하여 상대적으로 난방수의 흐름이 더 크게 하여 열전달율을 개선하고 이로써 온수를 보다 신속히 생성될 수 있도록 한 것이다.The heat exchanger plate of the present invention has a larger flow of heating water in comparison with direct water, thereby improving heat transfer rate and thereby generating hot water more quickly.

본 발명에 의한 열교환판은 도 5의 사시도와 도 6의 평면도에서 볼 수 있듯이 열교환판(110) 상면에 평탄한 마루부분(111)들이 일정 간격으로 이격되어 형성됨과 함께 그 마루부분들에서 전측으로 동일 평면상으로 연장된 연장부분(112)들이 일정 간격 이격되어 형성되어 상면과 저면측에서 유동하는 직수와 난방수의 접촉면적이 증대되도록 하고, 상기 연장부분(112)들은 직수의 흐름을 상면에서 전체 면적으로 분산되도록 중심으로부터 외측 방향으로 경사지게 형성되며, 상기 연장부분(112)들 사이는 오목하게 형성된다. The heat exchange plate according to the present invention is formed on the top surface of the heat exchange plate 110 as shown in the perspective view of FIG. 5 and the top view of FIG. Extension parts 112 extending in a plane are formed at regular intervals so that the contact area between the direct flow and the heating water flowing from the upper surface and the bottom surface is increased, and the extension portions 112 allow the entire flow of the straight water to flow from the upper surface. It is formed to be inclined in an outward direction from the center so as to be dispersed in an area, and the extension portions 112 are formed concave.

또한, 상기 열교환판은 난방수 인입구에서 배출구 사이의 직선 영역에서의 마루부분(121)들의 폭(d1)이 인입구와 배출구의 곡선영역의 마루부분들의 폭(d2) 보다 더 작게 형성함으로써, 상측에 접합되는 열교환판의 요부 저면과 용접되는 면적이 더 폭(d2)의 대응된 부분에서 상대적으로 더 크게 되어 그에 인접한 부분에서의 유체의 흐름 저항이 상대적으로 더 크게 되고, 상기 연장부분들의 수가 곡선 영역에서 보다 직선 영역에서 더 많게 형성함으로써 곡선 영역에서의 직수의 흐름이 직선 영역에서의 흐름 보다 원활하게 되어 결국 직수가 열교환판 전체 면적에 걸쳐 분산되어 유동할 수 있게 된다. In addition, the heat exchange plate has a width d1 of the floor portions 121 in the straight region between the outlet and the outlet of the heating water inlet smaller than the width d2 of the floor portions of the curved region of the inlet and the outlet. The area welded with the recess bottom of the heat exchanger plate to be joined is relatively larger in the corresponding portion of the width d2, so that the flow resistance of the fluid in the adjacent portion is relatively larger, and the number of the extension portions is curved. By forming more in the linear region than in the flow of the direct water in the curved region is smoother than the flow in the linear region so that the direct water can be dispersed and flowed over the entire heat exchange plate area.

본 발명에 따라, 상기한 본 발명의 열교환판(110)을 이용한 열교환기(200)가 도 7에 도시되어 있으며, 난방수 입출구(201,202)와, 온수로서 가열될 직수 유입구(203), 온수 배출구(204)들이 형성되고 측단부에는 하방으로 플랜지가 형성된 상판(110)과, 차례로 통상의 피시본(fishbone)형의 열교환판(210)과 본 발명에 따른 열교환판(110)이 교대로 이격 배치되어 이루어지며, 상기 열교환판(210)의 요부의 저면은 열교환판(110)의 상면의 마루부분(121)에 통상의 방법으로 용접에 의해 접합되며, 그 접합부분을 도 6에서 점으로 표시되었다.According to the present invention, the heat exchanger 200 using the heat exchanger plate 110 of the present invention is shown in FIG. 7, and the heating water inlet and outlet 201 and 202, a direct water inlet 203 to be heated as hot water, and a hot water outlet. 204 are formed and the upper end portion 110 is flanged downward at the side end, and in turn, the normal fishbone heat exchange plate 210 and the heat exchange plate 110 according to the present invention are alternately spaced apart The bottom surface of the recessed portion of the heat exchange plate 210 is joined to the floor portion 121 of the top surface of the heat exchange plate 110 by welding in a conventional manner, and the junction portion is indicated by a dot in FIG. 6. .

상기 열교환판(110)의 저면과 그 하측에 배치되는 피시본 형태의 열교환판(210) 상면으로 이루어지는 난방수 흐름 공간에서는 상기 열교환판(110)의 마루부분(121)과 동일 평면상의 연장부분(122)들이 형성되고, 연장부분들 사이는 요홈으로 형성되는 구조로, 상기 열교환판(110)의 상측과 하측으로 동일 높이로 이루어지는 하측의 난방수 체적이 상측의 직수 체적 보다 더 크게 된다. In the heating water flow space consisting of a bottom surface of the heat exchange plate 110 and an upper surface of the heat exchange plate 210 of a fishbone type disposed below the heat exchange plate 110, an extended portion coplanar with the floor portion 121 of the heat exchange plate 110 ( 122) are formed, and between the extension portions are formed in the groove, the lower heating water volume consisting of the same height to the upper side and the lower side of the heat exchange plate 110 is larger than the direct volume of the upper side.

상기 열교환판(110)의 마루부분들과 연장부들 및 그 연장부들 사이의 요홈 구조(도 9 참조)로 난방수와 직수의 전열 면적이 증대된다. The heat transfer area of the heating water and the direct water is increased by the floor portions and the extension parts of the heat exchange plate 110 and the groove structure (see FIG. 9) between the extension parts.

또한, 열교환판(110) 저면측의 공간으로 이루어지는 난방수 흐름 공간이 도 8의 단면도에서 볼 수 있듯이 증대되어 피시본 형태의 열교환판(210) 상면의 요철부분(211,212)을 타고 넘어 유동하는 난방수의 압력 강하가 종래 피시본 형태의 열교환판(210)들만으로 이루어지는 경우보다 완화되어 난방수의 흐름이 보다 원활하게 되고 열교환으로 인한 난방수 온도 저하가 상대적으로 작게 됨으로써, 결국 열교환판(110) 상면의 유로에서 유동하는 직수와의 온도 차가 종래의 열교환판(210)들만으로 이루어지는 경우 보다 크게 된다. 따라서, 열교환판(110)을 통해 전달되는 열량이 증대됨에 따라 열교환 효율이 향상되며, 온수 생성이 보다 신속히 이루어질 수 있게 된다.In addition, the heating water flow space consisting of the space on the bottom surface side of the heat exchange plate 110 is increased, as shown in the cross-sectional view of Figure 8 heating to flow over the uneven portions 211,212 of the upper surface of the heat exchange plate 210 of the fishbone type The pressure drop of the water is alleviated compared to the case of only the heat exchange plate 210 of the conventional fishbone type, so that the flow of the heating water becomes smoother, and the temperature decrease of the heating water due to the heat exchange is relatively small, resulting in the upper surface of the heat exchange plate 110. The temperature difference with the direct flow flowing in the flow path is larger than that of the conventional heat exchange plate 210 only. Therefore, as the amount of heat transferred through the heat exchange plate 110 is increased, heat exchange efficiency is improved, and hot water is generated more quickly.

또한, 상기한 실시예는 본 발명의 열교환판(110)들을 기존의 피시본 형태의 열교환판(210)과 함께 사용할 수 있음을 보여주는 것이나, 본 발명의 열교환판들만 으로 열교환기를 구성하거나 다른 형태의 종래 열교환판들과 함께 사용할 수 있음은 당연하다.In addition, the above embodiment shows that the heat exchange plate 110 of the present invention can be used together with the heat exchange plate 210 of the existing fishbone form, but the heat exchanger alone or other forms of heat exchange plate of the present invention Of course, it can be used with conventional heat exchange plates.

본 발명의 제 2 열교환판은 난방수 유동 체적이 직수(온수) 체적 보다 더 크게 되어 전열 효율이 향상되고 열교환판 전체 영역에 걸쳐 난방수와 직수 흐름이 분산됨으로써 이러한 제 2 열교환판을 이용한 열교환기는 열교환 효율이 향상되고 온수가 보다 신속히 생성될 수 있게 된다.In the second heat exchanger plate of the present invention, the heating water flow volume is larger than the direct water (hot water) volume, so that the heat transfer efficiency is improved and the heating water and the direct water flow are dispersed over the entire heat exchanger plate. Heat exchange efficiency is improved and hot water can be produced more quickly.
