Abstract

Abstract The invention relates to a heat exchanger for an electronics cabinet with a folded surface profile in which, alternatingly on both faces every other fold is closed off gastight or dustproof by a cross cover. With such an air/air heat exchanger the waste heat from the interior of an electronics cabinet can be dissipated to the outside when the electronics cabinet is closed dusttight. To facilitate production of the folded surface profile, the cross covers are integrally formed onto the folds. Such a folded surface profile, in which the folds and the cross covers form one integral component, is preferably produced as a deepdrawn part, so it is possible to make the component from plastic. In another embodiment, the folded surface profile can be a plastic injection molding.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 89 words
In an electronics cabinet, a heat exchanger comprising a folded surface profile having a depth of each fold of the folded surface profile approximately six times a width of each fold of the folded surface profile to facilitate forming in a single deep drawing operation from a single piece of plastic material, wherein alternatingly on both faces, every other fold is closed gastight by a cross cover, the cross covers being integrally formed also from the single piece of plastic material, onto the folds of the folded surface profile.
Claim 2
Dependent Claim 89 words
In an electronics cabinet, a heat exchanger comprising a folded surface profile having a depth of each fold of the folded surface profile approximately six times a width of each fold of the folded surface profile to facilitate forming in a single deep drawing operation from a single piece of plastic material, wherein alternatingly on both faces, every other fold is closed gastight by a cross cover, the cross covers being integrally formed also from the single piece of plastic material, onto the folds of the folded surface profile.
Claim 3
Dependent Claim 26 words
The heat exchanger according to claim 1, further comprising a plate-shaped tab provided on one face of the folded surface profile, parallel to its side surfaces.
Claim 4
Dependent Claim 31 words
The heat exchanger according to claim 1, further comprising a cover for one of the side surfaces of the folded surface profile, wherein the cover is provided with a plate-shaped tab.
Claim 5
Dependent Claim 14 words
The heat exchanger according to claim 1, further comprising bellows walls provided with obstructions.
Claim 6
Dependent Claim 43 words
The heat exchanger according to claim 4, wherein the distance between the bellows walls in the folded surface profile is selected as a function of the intended flow velocity of the air in the folds so a turbulent flow develops in the folds.
