Abstract

In a rectangular heat exchanger for electronic equipment wherein part of said equipment is placed on one end wall of the heat exchanger while air is brought into the heat exchanger by fan means located towards the other end wall and said air is channeled in the heat exchanger by a plurality of guide vanes extending generally radially outwards from a zone surrounding said fan means, the improvement therein wherein said heat exchanger includes an elongated resilient strip which has the inner end resting on a bottom wall of the heat exchanger, with the center portion thereof going around said fan means zone and the outer end extends across the mouths of flow channels which it is desired to cut off thereby increasing the air flow to the other channels to enhance the cooling to the electronic components.

Claims

1. In a rectangular heat exchanger for electronic equipment wherein part of said equipment is placed on one end wall of the heat exchanger while air is brought into the heat exchanger by fan means located towards the other end wall and said air is channeled in the heat exchanger by a plurality of guide vanes extending generally radially outwards from a zone surrounding said fan means, the improvement therein wherein said heat exchanger includes an elongated resilient spiral strip which has the inner end resting on a bottom wall of the heat exchanger, with the center portion thereof going around said fan means zone and the outer end extends across the mouths of flow channels which it is desired to cut off thereby increasing the airflow to the other channels to enhance the cooling to the electronic components.

2. In a heat exchanger as claimed in claim 1, including a lower outlet in said zone to allow water to drip therethrough, a tab in the center portion of said strip designed to fit in said outlet.

3. In a heat exchanger as claimed in claim 2, said strip outer end having a three-pronged grip to engage one of said guide vanes.

4. In a heat exchanger as claimed in claim 3, said strip inner end having a hairpin bend to increase the resilient effect.
