Heat exchanging apparatus

According to the present invention there is provided a small-sized thermosiphon free from deterioration in its cooling efficiency caused by pressure loss of a refrigerant and in which a two-phase flow of a fluid to be cooled is sure to be distributed uniformly. The thermosiphon includes a cooling cylinder 1 having a plurality of independent refrigerant tanks 2 formed by partition walls 1c which are disposed between fluid inlet port 1a and outlet port 1b inside the cylinder, and a plate fin type heat exchanger 50 extending inside the cylinder through the partition walls 1c hermetically sealably. Under this construction, it is not necessary to use pipes for the circulation of refrigerant C between the refrigerant tanks 2 and refrigerant circulation paths 54 in the heat exchanger 50, thus preventing the deterioration of the cooling efficiency caused by pressure loss of the refrigerant. Besides, it also becomes unnecessary to use a to-be-cooled fluid pipe for the connection between plural refrigerant tanks, whereby a two-phase flow of the fluid to be cooled is sure to be distributed uniformly and the deterioration of the cooling efficiency is prevented, thus permitting reduction in the size of the thermosiphon.
