SPIRAL BAFFLE BOARDS –SEPARATE TYPE / STRAIGHT TYPE–
■ GUIDE FOR SPIRAL BAFFLE BOARDS ● Features • Cooling water in spirals can cool down the core more efficiently than those on normal baffle boards. • Since it is plastic, rust will not be plugged in the cooling water path. • It can be cut including tip shape to fit into cooling space. On the other hand, it does not bend easily since it includes glass fiber. (Pull strength about 490N/mm 2 {50kgf/mm 2 }).

■ Notes on handling ● Notes Water leakage sometimes occurs even when the baffle boards are installed according to the recommended dimensions in the below installation hole forming example.
Conceivable causes are as follows. • Deformation of the mounting board • Large distance between the fixing position of the mounting board and the spiral baffle board (The retaining force is reduced.) • Random variations between O–rings In such a case, increase the number of fixing points and also seal the periphery of the mounting location using an O–ring. Make the mounting hole somewhat shallower than the recommended value, and perform adjustment using additional forming. ● Example
