Repairing or replacing a heat-generating instrument in a heat collector entails providing an electromagnetic valve on an upstream side of a fluid passage for supplying fluid pressure to a heat-collecting diaphragm (101). The heat collector has a heat-collecting diaphragm (101) for deforming upon receipt of a fluid pressure to contact a radiating surface of the heat-generating instrument, a heat collector casing fixing the heat-collecting diaphragm thereon for defining a pressure chamber to apply the fluid pressure to the heat-collecting diaphragm and a valve device provided on a fluid inlet side of the pressure chamber for opening and closing a fluid passage. The heat collector can be detached from a heat-generating instrument without draining a heat medium out of the heat collector. The heat collector is applicable to a cooling system for cooling electric apparatuses inside, say, a cellular phone base station.
