The holding elements (16,18) are in channel form arranged in the spacer plate (10) on the same side as the truncatedly conical spacer humps (14) and deep enough to enclose the pipes (22) at least half way round. The humps are arranged equi-spaced in lines and columns and the channels (16) for the humps also in lines and columns as opposed to the supplementary channels (18) which extend diagonally to the lines and columns of channels. A circular channel between every four humps ensures that the humps coincide in pairs with the lines and columns of pipes, using the pipes for heating and cooling medium. |
