VAPOR COOLING HEAT EXCHANGER - TOYOTA JIDOSHOKKI KK

Title:

VAPOR COOLING HEAT EXCHANGER

Document Type and Number:

WIPO Patent Application WO/2011/058924

Kind Code:

A1

Abstract:

A vapor cooling heat exchanger is provided with: a partition wall (19) for partitioning path (21) for a fluid to be cooled through which a fluid to be cooled flows, and path (24) for a refrigerant through which a refrigerant for cooling the fluid to be cooled flows; and fins which are disposed within path (21) for a fluid to be cooled, and which is thermally connected to the partition wall (19). The fins constitute a first fin (31) and a second fin (30), the local heat flux of which on the partition wall (19) is smaller than the first fin (31). The first fin (31) and the second fin (30) are arranged on the basis of the relationship between the local heat flux on the partition wall (19) and the heat flux limit of the refrigerant. As a consequence, the occurrence of local burn-outs on the vapor cooling heat exchanger is suppressed.
