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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A fixing structure for fixing a heat exchanger to a case, the heat exchanger having 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, wherein the fixing structure comprising:   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, wherein   the fixing portion is disposed at a position where a composite vibration mode of not greater than 1000 Hz is minimum, except for four corners of the heat exchange surface and except for a position corresponding to an antinode part of a natural vibration mode of the heat exchanger.   
     
     
         2 .- 4 . (canceled) 
     
     
         5 . The fixing structure according to  claim 1 , wherein the fixing portion is disposed at the position where a frequency of a vibration mode of the heat exchanger is different from a natural frequency of a wall surface of the case.
