A multi-walled material 1, has tubing 2, inserted into channels 3, from one open end to the other. At each end the tubing is curved back typically 180 degrees forming a loop to run through another empty channel in parallel within the same multi-walled material. This process is repeated until the desired amount of tubing is inserted into the multi-walled material. To secure the exposed turnaround of each loop of tubing 4, they are laid into a pre formed channel, 5. Any suitable design of preformed section or component supports the tubing and facilitates free passage of fluid without tube deformation such as depicted in 6, with cover examples 7, with the purpose of securing the tubing 2 in position. |
