Description
본 발명은 에어콘등의 열교환기용으로 이용되는 적층형 증발기를 형성함에 있어서, 상기 증발기를 형성하는 각 플레이트에 상호 대칭되는 유로벽을 다단으로 형성하고 이 유로벽들의 사이에는 여러개의 요철부를 형성하여 상기 유로를 따라 흐르는 냉매의 방열작용을 하도록 하므로서 상기 유로벽에 의한 증발기의 유로 전체의 냉매 압력강하량을 동일할 수 있도록 한 열교환기용 적층형 증발기의 유로에 관한 것이다.The present invention is to form a multi-layer evaporator used for heat exchangers, such as air conditioner, the flow path wall symmetrical to each other forming the plate forming the evaporator in a multi-stage and formed a plurality of uneven parts between the flow path wall to form the It relates to a flow path of a stacked evaporator for a heat exchanger so that the refrigerant pressure drop of the entire flow path of the evaporator by the flow path wall to be the same so as to perform a heat radiation action of the refrigerant flowing along.
일반적으로 에어콘 등의 열교환기에 설치되어 방열작용을 하면서 열교환을 하는 증발기는 냉매 유입구와 배출구를 구비하고 이들 사이에는 상기 냉매가 순환되는 유로를 구비하며 이 유로를 통하여 냉매가 순환될 때 열교환이 이루어지게 되고 상기 증발기에서 열을 방열시키도록 구성되어 있었다.In general, an evaporator installed in a heat exchanger such as an air conditioner to perform heat dissipation and having a heat dissipation has a refrigerant inlet and an outlet, and a flow path through which the refrigerant is circulated therebetween, so that heat exchange occurs when the refrigerant is circulated through the passage. And dissipate heat in the evaporator.
한편, 상기와 같이 구성되는 종래의 열교환기용 증발기는 양단에 냉매 유입구와 배출구를 형성하고 이들 사이에 냉매순환용 튜브를 지그재그 형태로 형성하여 설치하며 상기 냉매순환용 튜브의 외측에는 다수의 방열핀(Fin)을 설치하여 구성되어 있고 상기 냉매순환용 튜브를 따라 냉매가 순환을 할 때 발생되는 열을 상기 방열핀으로써 방열시키도록 구성되어 있었다.Meanwhile, the conventional heat exchanger evaporator configured as described above forms a refrigerant inlet and an outlet at both ends, and forms a refrigerant circulation tube in a zigzag form therebetween, and a plurality of heat dissipation fins outside the refrigerant circulation tube. And heat radiation generated when the coolant circulates along the coolant circulation tube.
그러나, 상기와 같은 종래의 것은 냉매의 순환을 위하여 설치되는 튜브가 지그재그 형상으로 되어 있으면서 이들의 방열을 위하여 적정한 간격을 유지시켜야 하므로써 상기 증발기의 전체적인 부피가 크게 되었고 상기 튜브들의 사이에 다수의 방열핀을 설치해야 하기 때문에 상기 방열핀들의 설치작업이 매우 난해하면서도 복잡하게 되는 폐단이 있었으며, 상기 방열핀들이 일정한 간격이 유지되지 않을 경우, 상기 방열핀에 의한 방열작용이 고르게 형성되지 않아 방열효과가 약화되는 폐단이 있었다.However, the above-described conventional method has a large zigzag tube to maintain the proper spacing for the heat dissipation of the tube is installed in the zigzag shape for the circulation of the refrigerant has increased the overall volume of the evaporator and a plurality of heat dissipation fins between the tubes Since the installation work of the heat dissipation fins has to be installed very difficult and complicated, there was a closed end, and if the heat dissipation fins were not kept at regular intervals, there was a closed end that the heat dissipation effect by the heat dissipation fins was not formed uniformly, and the heat dissipation effect was weakened. .
또한, 상기 방열핀들과 상기 냉매순환용 튜브의 접촉부위가 매우 작기 때문에 상기 방열핀으로의 열전달 면적이 적게 되고 상기 방열핀의 설치에 비하여 방열효과가 매우 적게 되는 등의 결점이 있었고 상기 방열핀들이 박판상으로 형성되어 있기 때문에 작은 충격에도 상기 방열핀이 쉽게 손상되는 점 등의 문제점이 있었다.In addition, since the contact portion between the heat dissipation fins and the refrigerant circulation tube is very small, the heat transfer area to the heat dissipation fin is reduced, and the heat dissipation fin is very thin as compared with the installation of the heat dissipation fin. Since there is a problem such that the heat radiation fin is easily damaged even with a small impact.

이상과 같이 구성된 본 발명은 상기 에어콘등의 열교환기용으로 이용되는 적층형 증발기를 형성함에 있어서, 상기 증발기를 형성하는 각 플레이트(1)에 상호 대칭되는 유로벽(2)을 여러개 형성하여 유로(3)를 구성하고 이 유로(3)의 양방에는 유입부(4)와 유출부(5)가 대각방향으로 형성되도록 하며, 상기 유로벽(2)에 의하여 형성되는 유로상에는 여러개의 요철부(6)를 형성하고 상기 유로벽(2)과 유로(3) 및 요철부(6)가 형성된 각각의 플레이트(1)들을 상호 대향되는 상태로 결합하여 코어를 구성하게 되는 것으로, 상기 유입부(4)를 통하여 냉매가 플레이트(1)의 유로(3)상으로 유입되면, 상기 유로벽(2)에 의하여 유출부(5)까지 대각방향으로 냉매가 흐르게 되며 상기 유로(3)의 초입으로 유입된 냉매는 하방과 측면으로 흐르게 되면서 상기 유로벽(2)을 따라 타측으로 이동하게 되어 유출부(5)에 도달하게 되므로 상기 플레이트(1)의 전체적인 압력강하량이 거의 동일하게 되고 상기 요철부(6)에 의하여 유로(3)와 유로벽(2)을 따라 흐르는 냉매의 방열작용이 이루어지게 된다.According to the present invention configured as described above, in forming a laminated evaporator used for a heat exchanger such as an air conditioner, a plurality of flow path walls 2 symmetrically formed on each plate 1 forming the evaporator may be provided. The inflow part 4 and the outflow part 5 are formed in diagonal directions on both sides of this flow path 3, and several uneven parts 6 are formed on the flow path formed by the flow path wall 2, respectively. And each of the plates 1 on which the flow path wall 2, the flow path 3, and the uneven part 6 are formed to face each other is configured to form a core. When the coolant flows into the flow path 3 of the plate 1, the coolant flows in the diagonal direction to the outlet portion 5 by the flow path wall 2, and the coolant flowed into the inlet of the flow path 3 is downward. While flowing to the side and the other side along the flow path wall (2) Since the total pressure drop of the plate 1 is almost equal to the outlet part 5 and reaches the outlet part 5, the refrigerant flowing along the flow path 3 and the flow path wall 2 by the uneven part 6 is formed. The heat dissipation is achieved.
또, 상기 본 발명의 다른 실시예에서와 같이 상기 유로(3)를 형성함에 있어서, 유로패턴에 따라 서로 대향되도록 격벽(7)을 상기 일부의 유로벽(2)에 연장형성하여 냉매의 흐름이 지그재그로 이루어질 수 있도록 구성하게 되면, 냉매의 흐름패턴을 지그재그로 할 수 있게 되고 압력강하량이 전체적으로 동일하게 되면서 여러개의 유로벽(3)이 하나의 유로패턴을 이루게 할 수 있다.Further, in forming the flow path 3 as in the other embodiment of the present invention, the partition 7 extends to the part of the flow path walls 2 so as to face each other according to the flow path pattern so that the flow of the coolant flows. When configured to be zigzag, it is possible to zigzag the flow pattern of the refrigerant and the pressure drop amount is the same as the entire flow path wall (3) can form a single flow path pattern.
또한, 도 5에서와 같은 실시예는 상기 유입부(4)와 유출부(5)는 대각방향으로 형성되도록 한 상태에서 상기 유로벽(201)들을 대각선 방향으로 형성하여 이를 따라 흐르는 냉매가 대각상태로 흐르도록 하므로서 상기 유입구에서 유출구측에 이르는 유로를 직접 연결하는 방식이 형성되며 이에 따라 상기 유로에서의 압력강하량이 고르게 되도록 한 것이다.In addition, in the embodiment as shown in FIG. 5, the inflow part 4 and the outflow part 5 are formed in a diagonal direction, and the flow path walls 201 are formed in a diagonal direction so that the refrigerant flowing therefrom is in a diagonal state. In order to flow in the form of a method of directly connecting the flow path from the inlet to the outlet side is formed so that the pressure drop in the flow path is even.
이상과 같은 본 발명은 상기와 같이하여 열교환기용 적층형의 증발기를 구성함에 있어서, 상기 각 플레이트(1)에 대각방햐으로 냉매가 흐르도록 하는 유로벽(2)과 유로(3)를 형성하고 이들 사이에는 방열작용을 하는 요철부(6)를 형성하도록 하므로써 상기 플레이트(1)의 유로를 따라 흐르는 냉매의 압력강하량이 상기 플레이트(1) 전체에서 고르게 분포되도록 할 수 있게 되며, 이에 따라 상기 유입부(4)와 유출부(5) 부근의 압력강하량이 거의 동일하게 되어 열교환면적이 상기 플레이트(1)의 전체에서 고르게 이루어지게 된다.The present invention as described above forms a flow path wall 2 and a flow path 3 through which the refrigerant flows diagonally in each plate 1 in the stack type evaporator for a heat exchanger as described above. By forming the concave-convex portion 6 to dissipate therebetween, the pressure drop of the refrigerant flowing along the flow path of the plate 1 can be evenly distributed throughout the plate 1, and thus the inlet portion The pressure drop amounts near (4) and the outlet portion (5) are almost the same so that the heat exchange area is evenly made throughout the plate (1).
따라서, 상기와 같은 열교환기용 적층형 증발기를 구성하므로써 이 증발기의 열교환 효율을 크게 향상시킬 수 있게 되고, 종래에 비하여 상기 증발기의 부피를 크게 줄일 수 있게 되며 상기 각 플레이트상에 형성된 유로를 통하여 냉매가 원활하게 순환하도록 하므로써 냉매순환에 따른 열교환이 효과적으로 이루어지게 되고 또한, 상기 각 플레이트에 형성된 다수개의 요철부가 방열작용을 하도록 하므로써 종래와 같이 별도의 방열핀을 설치할 필요가 없게 되며, 상기 요철부에 의하여 상기 플레이트의 열을 직접방식으로 방열시킬 수 있게 되므로 방열효과를 크게 향상시킬 수 있게 되고 이에 따라 상기 증발기의 효율을 크게 증대시킬 수 있게 되는 점 등의 특징을 지닌 것이다.Therefore, by configuring the laminated evaporator for the heat exchanger as described above, the heat exchange efficiency of the evaporator can be greatly improved, and the volume of the evaporator can be greatly reduced as compared with the conventional one, and the refrigerant is smoothly flowed through the flow path formed on each plate. The heat exchange according to the refrigerant circulation is effectively made by circulating in a circulating manner, and the plurality of uneven parts formed on the respective plates have a heat dissipation effect, so that a separate heat dissipation fin does not need to be installed as in the related art. Since it is possible to heat the heat of the direct method, it is possible to greatly improve the heat dissipation effect and accordingly have the characteristics such that it can greatly increase the efficiency of the evaporator.
