하부판(40)에 설치되는 격벽(43)은 냉각수의 흐름에 와류가 발생되지 않도록 안내하여 유로(42)를 통해 냉각수가 빠르게 흐를 수 있도록 형성되며, 가장자리를 따라 형성된 밀폐부재(44)는 발열판(50)이 설치된 형태에 맞게 설치된다.The bulkhead 43 installed on the lower plate 40 guides the flow of the cooling water so that no vortex is generated so that the cooling water can flow quickly through the flow path 42, and the sealing member 44 formed along the edge is a heating plate ( 50) is installed according to the installed form.

상부판(30)은 하부판(40)과 상하 대칭되는 형태로 설치됨에 따라 다수의 격벽(33)과, 격벽(33)에 의한 유로(32) 및 가장자리를 따라 설치되는 밀폐부재(44)가 동일하게 설치될 수 있다.As the upper plate 30 is installed in a vertically symmetrical manner with the lower plate 40, the plurality of partition walls 33, the passage 32 by the partition walls 33, and the sealing member 44 installed along the edge are the same. can be installed appropriately.

발열판(50)을 상,하부판(30)(40)에 설치함에 있어 본 발명에서는 도 5에서와 같이 냉각수가 가운데 발열판(50)을 두고 하부에서 상부로 흐르는 곡면유로부가 형성되는 것임에 따라 발열판(50)이 상,하부판(30)(40)의 결합으로 형성되는 몸체(10) 전체면적에 설치되지 않고 냉각수가 회전할 수 있는 곡선유로부(60)를 형성하기 위해 도 3에서와 같이 간격을 두고 설치된다.In installing the heating plate 50 to the upper and lower plates 30 and 40, in the present invention, as shown in FIG. 5, the heating plate 50 is placed in the middle and a curved flow path portion in which cooling water flows from the bottom to the top is formed. 50) is not installed on the entire area of the body 10 formed by the combination of the upper and lower plates 30 and 40, but is spaced apart as shown in FIG. left and installed

발열판(50)이 설치되는 상,하부판(30)(40)의 가장자리에는 냉각수의 누수방지를 위한 밀폐부재(44)가 설치되며, 발열판(50)이 설치되지 않고 상,하부판(30)(40)의 상하결합에 의해 밀폐가 이루어지는 부분은 돌출면(45)이 형성된다.A sealing member 44 is installed at the edge of the upper and lower plates 30 and 40 where the heating plate 50 is installed to prevent leakage of cooling water, and the heating plate 50 is not installed and the upper and lower plates 30 and 40 are installed. ) The protruding surface 45 is formed in the part where the sealing is made by the upper and lower coupling.

상기 돌출면(45)은 상,하부판(30)(40)에 각각 형성되어 상,하부판(30)(40)의 상하결합시 맞닿게 되어 밀폐가 이루어지며, 밀폐부재(44)의 설치면보다 각각 돌출되어 형성됨에 따라 발열판(50)의 설치에 관계없이 밀착결합이 이루어진다.The protruding surfaces 45 are formed on the upper and lower plates 30 and 40, respectively, and come into contact with each other when the upper and lower plates 30 and 40 are coupled up and down, so that sealing is achieved, and the sealing member 44 is installed. As it is formed by protruding, it is closely coupled regardless of the installation of the heating plate 50 .
