The heat exchanger comprises a pipe 2 having an outer wall, the pipe being divided into a plurality of elongate sections by one or more dividing walls. The dividing walls permit the transfer of heat between fluids flowing in the elongate sections, and the heat exchanger permits fluid to flow in a first direction along at least one of the elongate sections while subsequently permitting fluid to flow in a second, opposing direction along at least one of the other elongate sections. The heat exchanger may include end caps 1,3 on either end of the pipe, the end caps providing both inlets 'a','c' and outlets 'b','d' for the fluids. Portions of the outer wall may be removed to provide additional fluid inlets and/or outlets. The heat exchanger may be used as a skirting board made from extruded aluminium, high-density ceramics or PVC as part of a ventilation system of a building, the fluids being stale and fresh air, or any other gas or liquid. |
