A heat exchanger (100) is disclosed for exchanging heat with a medium across a substantially planar surface. The exchanger (100) comprises: a heat exchanging panel (101); a fluid circuit comprising a first chamber (104) disposed at a first end of the panel (101), a second chamber (105) disposed at a second end of the panel (101), a plurality of passages (103) which extend along the panel between the first and second chambers (104,105), and a duct (107) which extends between the first and second chamber (104,105); a fluid disposed within the circuit; wherein, the plurality of passages (103) are arranged in thermal communication with the panel (101) and are arranged to communicate the fluid from the first chamber (104) to the second chamber (15), and the duct (107) is arranged to communicate fluid from the second chamber (105) to the first chamber (104). |
