Document Type and Number:
Japanese Patent JP2015152244
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cooling device capable of improving efficiency in a heating operation of an air conditioning cycle.SOLUTION: A cooling device 100 is connected to an air conditioning cycle 100c through a switch valve 2. The switch valve 2 is disposed at a downstream side of a first outdoor heat exchanger 3, and switches flow of a refrigerant flowing out from the first outdoor heat exchanger 3. The cooling device 100 includes a second outdoor heat exchanger 5 exchanging heat between the refrigerant and outside air, and a cooling portion 30 radiating heat generated by a heating source to the refrigerant. The switch valve 2 switches a flow channel of the refrigerant so that the cooling portion 30 is connected to an upstream side of the second outdoor heat exchanger 5 in a cooling operation of the air conditioning cycle 100c, and the cooling portion 30 is connected to a downstream side of the second outdoor heat exchanger 5 in a heating operation of the air conditioning cycle 100c.
