PROBLEM TO BE SOLVED: To provide an ebullient cooler for circulating condensate to a refrigerant tank even at the time of inclining without bringing about a large scale in size of a constitution. SOLUTION: A radiator 4 has a lower tank coupled to an upper part of a refrigerant tank 3, and a plurality of radiating tubes 7 laminated on the upper part of the lower tank. The lower tank is partitioned therein by a refrigerant flow control plate 11 into an inlet chamber 12 and an outlet chamber 13. The laminated tubes 7 communicate with communicating parts 7a, 7b provided at both ends in a longitudinal direction in a laminating direction to form an inlet side communicating part and an outlet side communicating part. And, communicating ports 7a for communicating with refrigerant passages communicate in the laminating direction to form communicating passages between channels at the respective tubes 7. The passages between the channels communicate with the chamber 13 in the lower tank, The plate 11 guides refrigerant vapor obtained by ebullition in the tank 3 to the inlet side communicating part even at the time of inclining, and guides condensate dripping from the passages between the channels to a liquid return passage 5a in the tank 3. |
