Abstract

A heat exchanger has a rectangular parallelepiped shape in which refrigerant flows. When sides configuring the heat exchanger having the rectangular parallelepiped shape include a first side, a second side, and a third side, a length of the third side is shortest. A surface surrounded by the first side and the second side is a heat exchange surface of the heat exchanger. A fixing structure for fixing the heat exchanger to a case includes at least one fixing portion disposed on at least one of a surface surrounded by the first side and the third side and a surface surrounded by the second side and the third side. The fixing portion is disposed at a position where a composite vibration mode of not greater than 1000 Hz is minimum.

Description

CROSS REFERENCE TO RELATED APPLICATION

[0001] This application is based on Japanese Patent Application No. 2012-262209 filed on Nov. 30, 2012, the disclosure of which is incorporated herein by reference.TECHNICAL FIELD

[0002] The present disclosure relates to a fixing structure for a heat exchanger in which refrigerant flows.BACKGROUND ART

[0003] Patent literature 1 describes a cooling evaporator in an air conditioning unit for a vehicle, and the cooling evaporator is mounted in an air conditioning unit case through elastic members at four corners of the evaporator. The elastic member absorbs vibration of the evaporator. When the vibration absorbing action will be described in more detail, the evaporator is coupled with a compressor in an engine compartment of the vehicle through a refrigerant piping, and the compressor is fitted to an engine of the vehicle and driven by the engine. For that reason, the compressor vibrates integrally with the engine. The compressor per se vibrates due to ...
