Abstract: This disclosure relates to an adjustable heat source simulation assembly includes at least one first simulation heater, a second simulation heater and a power output module. The at least one first simulation heater and the second simulation heater are configured to be disposed in a server chassis. The power output module is electrically connected to the at least one first simulation heater and the second simulation heater so as to control heating power of the at least one first simulation heater and the second simulation heater.

Abstract: A method for fabricating a heat-dissipating base structure is disclosed.

Abstract: A heat dissipating base structure includes a base; a plurality of heat dissipating fins disposed on the base and arranged in parallel to each other, each of the heat dissipating fins being formed with at least a first through hole and a second through hole corresponding to the first through hole; and at least a U-shaped heat pipe having a bending portion and two pipe leg portions extending from two ends of the bending portion respectively. The cross section of the pipe leg portions is smaller than the size of the first and second through holes. Each of the pipe leg portions is fixedly disposed in the first and second through holes at one side thereof respectively, and can move freely in the holes before being fixedly disposed.
