Insert for heat exchanger
First Claim
1. An insert for a heat exchanger having a plurality of tubes, the insert comprising:
- a base; and
a plurality of blades extending from the base, whereinat least one of the blades has a spring portion, which is resiliently deformable and configured to be resiliently inserted between two of the tubes,the spring portion includes two arms,one of the two arms has one thin portion defining one recess dented in one direction in a thickness direction,an other of the two arms has an other thin portion defining an other recess dented in an other direction in the thickness direction, andthe one thin portion and the other thin portion are resiliently movable in a width direction within a clearance formed by the recesses, while overlapping one another in the thickness direction, whereinthe one thin portion and the other thin portion have a flash therebetween, before the one thin portion and the other thin portion are resiliently moved in the width direction, andthe one thin portion and the other thin portion are configured to overlap one another in the thickness direction, when resiliently moved in the width direction, while crushing the flash.

Abstract
An insert is configured to be inserted into a heat exchanger having a plurality of tubes. The insert includes a base and a multiple blades. The blades are extended from the base. At least one of the blades has a spring portion. The spring portion is resiliently deformable and configured to be resiliently inserted between two of the tubes. The spring portion includes two arms. One of the two arms has one thin portion defining one recess dented in one direction in a thickness direction. The other of the two arms has the other thin portion defining the other recess dented in the other direction in the thickness direction. The one thin portion and the other thin portion are resiliently movable in a width direction within a clearance formed by the recesses, while overlapping one another in the thickness direction.
