ABSTRACT:
A cooling apparatus having a plurality of heat pipes is improved to reduce the condensation capacity of selected heat pipes when ambient air temperature is low, so as to facilitate start-up of the cooling apparatus from a state in which the working fluid in the heat pipes has been frozen. The cooling apparatus has a block of a high heat conductivity in which one end of each heat pipe serving as an evaporation section of the heat pipe is embedded. Heat radiation fins are attached to portions of the heat pipes exposed from the block, so that the exposed portions of the heat pipes serve as condensation sections of the respective heat pipes. There are two types of heat radiation fins: a first type of fins which are attached to all the heat pipes and a second type of fins which are attached only to selected heat pipes.
