Title:
HEAT EXCHANGER UNIT
Document Type and Number:
Japanese Patent JP2008121984
Kind Code:
A
Abstract:
To solve a problem wherein an operation mode disabling maximum capacity exhibition of a heat exchanger exists due to a coolant flowing only to a specific line although the coolant is in an overaccumulated state in the heat exchanger because the amount of heat exchanger differs by the presence/absence of condensed water sticking to the surface of the heat exchanger.
The coolant flows to either the balance tube 15a or balance tube 15b side by a branch unit 14 having an opening/closing device. The passage resistance of the balance tubes can thereby be changed according to each operating state to improve overaccumulation of the coolant in the heat exchanger and the flow of the coolant only to the specific line.
